HSBC USA Inc. Trigger Autocallable Contingent Yield Notes

$10,683,960 Notes Linked to the Least Performing of the iShares^® Russell 2000 ETF and iShares^® MSCI Emerging Markets ETF due on January 31, 2025

Investment Description

These Trigger Autocallable Contingent Yield Notes (the “Notes”) are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”) with returns linked to the Least Performing of the iShares^® Russell 2000 ETF and iShares^® MSCI Emerging Markets ETF (each, an “Underlying” and together, the “Underlyings”). The Notes will rank equally with all of our other unsecured and unsubordinated debt obligations. HSBC will pay a quarterly Contingent Coupon if the Official Closing Price of each Underlying on the applicable Coupon Observation Date (including the Final Valuation Date) is equal to or greater than its Coupon Barrier. Otherwise, no coupon will be paid for the quarter. HSBC will automatically call the Notes if the Official Closing Price of each Underlying on any quarterly Call Observation Date, commencing on January 29, 2021, is equal to or greater than its Initial Price. If the Notes are called, HSBC will pay you the Principal Amount of your Notes plus the Contingent Coupon for the applicable quarter, and no further amounts will be owed to you under the Notes. The Underlying with the lowest Underlying Return is the “Least Performing Underlying.” If the Notes are not called prior to maturity and the Final Price of the Least Performing Underlying is equal to or greater than its Downside Threshold, HSBC will pay you a cash payment at maturity equal to the Principal Amount of your Notes. If the Final Price of the Least Performing Underlying is less than its Downside Threshold, HSBC will pay you less than the full Principal Amount, if anything, resulting in a loss on your initial investment that is proportionate to the negative performance of the Least Performing Underlying over the term of the Notes, and you may lose up to 100% of your Principal Amount.

Investing in the Notes involves significant risks. HSBC may not pay any Contingent Coupons on the Notes. You may lose some or all of your Principal Amount. You will be exposed to the market risk of each Underlying on each Coupon Observation Date and any decline in the price of one Underlying may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the price of the other Underlying. Generally, the higher the Contingent Coupon Rate on a Note, the greater the risk of loss on that Note. The contingent repayment of principal only applies if you hold the Notes to maturity. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of HSBC. If HSBC were to default on its payment obligations, you may not receive any amounts owed to you under the Notes and you could lose your entire investment.

Features

q Contingent Coupon: HSBC will pay a quarterly Contingent Coupon payment if the Official Closing Price of each Underlying on the applicable Coupon Observation Date is equal to or greater than its Coupon Barrier. Otherwise, no coupon will be paid for the quarter.

q Automatically Callable: HSBC will automatically call the Notes and pay you the Principal Amount of your Notes plus the Contingent Coupon otherwise due for that applicable quarter if the Official Closing Price of each Underlying on any quarterly Call Observation Date, commencing on January 29, 2021, is equal to or greater than its Initial Price. If the Notes are not called, investors will potentially lose a portion of their Principal Amount at maturity.

q Contingent Repayment of Principal Amount at Maturity: If the Notes have not been previously called and the Official Closing Price of the Least Performing Underlying is not less than its Downside Threshold on the Final Valuation Date, HSBC will pay you the Principal Amount per Note at maturity plus the final Contingent Coupon. If the Official Closing Price of the Least Performing Underlying on the Final Valuation Date is less than its Downside Threshold, HSBC will pay a cash amount that is less than the Principal Amount, if anything, resulting in a loss on your initial investment that is proportionate to the decline in the Official Closing Price of the Least Performing Underlying from the Trade Date to the Final Valuation Date. The contingent repayment of principal only applies if you hold the Notes until maturity. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of HSBC.

Contingent Coupon payments on the Notes are not guaranteed. HSBC will not pay you the Contingent Coupon for any Coupon Observation Date on which the Official Closing Price of any Underlying is less than its Coupon Barrier.

Payment at Maturity (per $10 Note)       If the Notes are not called, you will receive a payment on the Maturity Date calculated as follows:   If the Final Price of the Least Performing Underlying is equal to or greater than its Downside Threshold, HSBC will pay you a cash payment on the Maturity Date equal to $10 per $10 Principal Amount of Notes, plus the final Contingent Coupon.³   If the Final Price of the Least Performing Underlying is less than its Downside Threshold, HSBC will pay you a cash payment on the Maturity Date that is less than the Principal Amount, equal to:   $10 × (1 + Underlying Return of the Least Performing Underlying).  

¹ Each Coupon Observation Date, Call Observation Date, Coupon Payment Date, the Final Valuation Date and Maturity Date are subject to postponement in the event of a Market Disruption Event or non-trading day, as described under “Additional Terms of the Notes—Valuation Dates” and “—Coupon Payment Dates, Call Payment Dates and Maturity Date” in the accompanying ETF underlying supplement. Each Coupon Observation Date on and after January 29, 2021 will also be a Call Observation Date.

² Contingent Coupons will be payable to the holders of record at the close of business on the business day immediately preceding the applicable Coupon Payment Date, provided that the Contingent Coupon payable upon Automatic Call or at maturity, as applicable, will be payable to the person to whom the principal amount upon Automatic Call or the Payment at Maturity, is payable. These Coupon Payment Dates are also Call Settlement Dates if the Notes are called on the related Call Observation Date.

³ Contingent repayment of principal is dependent on the ability of HSBC USA Inc. to satisfy its obligations when they come due.

	In this case, you will have a loss of principal that is proportionate to the decline in the Final Price of the Least Performing Underlying from its Initial Price and you will lose some or all of your Principal Amount.
Least Performing Underlying	The Underlying with the lowest Underlying Return.
Underlying Return	For each Underlying, calculated as follows: Final Price - Initial Price
	Initial Price
Downside Threshold	For each Underlying, 70% of its Initial Price, as indicated on the cover hereof.
Coupon Barrier	For each Underlying, 70% of its Initial Price, as indicated on the cover hereof.
Initial Price	For each Underlying, its Official Closing Price on the Trade Date, as indicated on the cover hereof.
Final Price	For each Underlying, its Official Closing Price on the Final Valuation Date.
Calculation Agent	HSBC USA Inc. or one of its affiliates.
Estimated Initial Value	The Estimated Initial Value of the Notes is less than the price you pay to purchase the Notes. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your Notes in the secondary market, if any, at any time. See “Key Risks — The Estimated Initial Value of the Notes, Which Was Determined by Us on the Trade Date, Is Less than the Price to Public and May Differ from the Market Value of the Notes in the Secondary Market, if Any.”

Investment Timeline

	The Initial Price of each Underlying was observed and the final terms of the Notes were determined.
	If the Official Closing Price of each Underlying is equal to or greater than its Coupon Barrier on any Coupon Observation Date, HSBC will pay you a Contingent Coupon on the applicable Coupon Payment Date. The Notes will automatically be called if the Official Closing Price of each Underlying on any Call Observation Date, commencing on January 29, 2021, is equal to or greater than its Initial Price. If the Notes are called, HSBC will pay you a cash payment per Note equal to $10.00 plus the Contingent Coupon otherwise due on that date.
	The Final Price and Underlying Return of each Underlying are determined on the Final Valuation Date. If the Notes have not been called and the Final Price of the Least Performing Underlying is equal to or greater than its Downside Threshold, HSBC will repay the Principal Amount equal to $10.00 per Note, plus the final Contingent Coupon. If the Notes have not been called and the Final Price of the Least Performing Underlying is below its Downside Threshold, HSBC will pay you a cash payment at maturity that will be less than the Principal Amount, if anything, resulting in a loss of principal proportionate to the decline of the Least Performing Underlying, equal to a return of: $10 × (1 + Underlying Return of the Least Performing Underlying) per Note

Investing in the Notes involves significant risks. You may lose some or all of your Principal Amount. Any payment on the Notes, including any repayment of principal, is subject to the creditworthiness of HSBC. If HSBC were to default on its payment obligations, you may not receive any amounts owed to you under the Notes and you could lose your entire investment.

You will be exposed to the market risk of each Underlying on each Coupon Observation Date and any decline in the price of one Underlying may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the price of the other Underlying. Generally, the higher the Contingent Coupon Rate on a Note, the greater the risk of loss on that Note.

Key Risks

An investment in the Notes involves significant risks. Some of the risks that apply to the Notes are summarized here. However, HSBC urges you to read the more detailed explanation of risks relating to the Notes generally in the “Risk Factors” section of the accompanying ETF underlying supplement and the accompanying prospectus supplement. HSBC also urges you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes.

¨ Risk of Loss at Maturity — The Notes differ from ordinary debt securities in that HSBC will not necessarily pay the full Principal Amount of the Notes. If the Notes are not called, HSBC will only pay you the Principal Amount of your Notes in cash if the Final Price of the Least Performing Underlying is greater than or equal to its Downside Threshold, and will only make that payment at maturity. If the Notes are not called and the Final Price of the Least Performing Underlying is less than its Downside Threshold, you will lose some or all of your initial investment in an amount proportionate to the decline in the Final Price of the Least Performing Underlying from its Initial Price. You may lose some or all of your Principal Amount at maturity.

¨ The Contingent Repayment of Principal Applies at Maturity — You should be willing to hold your Notes to maturity. If you are able to sell your Notes prior to maturity in the secondary market, you may have to sell them at a loss relative to your initial investment even if the price of each Underlying at that time is above its Downside Threshold.

¨ You May Not Receive any Contingent Coupons — HSBC will not necessarily make periodic coupon payments on the Notes. If the Official Closing Price of any Underlying on a Coupon Observation Date is less than its Coupon Barrier, HSBC will not pay you the Contingent Coupon applicable to that Coupon Observation Date. If the Official Closing Price of any Underlying is less than its Coupon Barrier on each of the Coupon Observation Dates, HSBC will not pay you any Contingent Coupons during the term of, and you will not receive a positive return on, your Notes. Generally, this non-payment of the Contingent Coupon coincides with a period of greater risk of principal loss on your Notes.

¨ The Estimated Initial Value of the Notes, Which Was Determined by Us on the Trade Date, Is Less than the Price to Public and May Differ from the Market Value of the Notes in the Secondary Market, if Any — The Estimated Initial Value of the Notes was calculated by us on the Trade Date and is less than the price to public. The Estimated Initial Value reflects our internal funding rate, which is the borrowing rate we pay to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the Notes may be lower if it were based on the prices at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the Notes to be more favorable to you. We determined the value of the embedded derivatives in the Notes by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the Notes that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your Notes in the secondary market (if any exists) at any time.

¨ The Price of Your Notes in the Secondary Market, if Any, Immediately After the Trade Date Will Be Less than the Price to Public — The price to public takes into account certain costs. These costs will include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes and the costs associated with structuring and hedging our obligations under the Notes. These costs, except for the underwriting discount, will be used or retained by us or one of our affiliates. If you were to sell your Notes in the secondary market, if any, the price you would receive for your Notes may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the prices of the Underlyings and changes in market conditions, and cannot be predicted with accuracy. The Notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Notes to maturity. Any sale of the Notes prior to maturity could result in a loss to you.

¨ If One of Our Affiliates Were to Repurchase Your Notes Immediately After the Settlement Date, the Price You Receive May Be Higher than the Estimated Initial Value of the Notes — Assuming that all relevant factors remain constant after the Settlement Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that may initially be used for customer account statements, if any, may exceed the Estimated Initial Value on the Trade Date for a temporary period expected to be approximately 9 months after the Settlement Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes that we will no longer expect to incur over the term of the Notes. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the Notes and any agreement we may have with the distributors of the Notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Settlement Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

¨ Reinvestment Risk — If your Notes are called early, the term of the Notes will be reduced and you will not receive any payment on the Notes after the applicable Call Settlement Date. There is no guarantee that you would be able to reinvest the proceeds from an automatic call of the Notes at a comparable rate of return for a similar level of risk. To the extent you are able to reinvest such proceeds in an investment comparable to the Notes, you may incur transaction costs. The Notes may be called as early as 12 months after issuance.

7

¨ The Notes Are Subject to the Credit Risk of the Issuer — The Notes are senior unsecured debt obligations of HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the Notes will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the Notes, including any Contingent Coupon payment or any repayment of principal at maturity or upon an automatic call, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the Notes and, in the event HSBC were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes and could lose your entire investment.

¨ Higher Contingent Coupons or Lower Downside Thresholds Are Generally Associated with an Underlying with Greater Expected Volatility and Therefore Can Indicate a Greater Risk of Loss —"Volatility" refers to the frequency and magnitude of changes in the price of an Underlying. The greater the expected volatility with respect to an Underlying on the Trade Date, the higher the expectation as of the Trade Date that the Underlying could close below its Coupon Barrier on a Coupon Observation Date, resulting in no Contingent Coupons payable on the Notes, or below its Downside Threshold on the Final Valuation Date, resulting in the loss of some or all of your investment. This greater expected risk will generally be reflected in a higher Contingent Coupon than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as a lower Downside Threshold or a higher Contingent Coupon) than for similar securities linked to the performance of an Underlying with a lower expected volatility as of the Trade Date. You should therefore understand that a relatively higher Contingent Coupon may indicate an increased risk of loss. Further, a relatively lower Downside Threshold may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of an Underlying can change significantly over the term of the Notes. The price of an Underlying for your Notes could fall sharply, which could result in a significant loss of principal, and the non-payment of one or more Contingent Coupons. You should be willing to accept the downside market risk of the Least Performing Underlying and the potential to lose some or all of your principal at maturity.

¨ Because the Notes Are Linked to the Performance of More Than One Underlying, There Is a Greater Risk of Contingent Coupons Not Being Paid and of You Sustaining a Significant Loss on Your Investment — The risk that you will not receive any Contingent Coupons and lose some or all of your initial investment in the Notes at maturity is greater if you invest in the Notes as opposed to substantially similar Notes that are linked to the performance of only one Underlying. With two Underlyings, it is more likely that the Official Closing Price of any Underlying will be less than its Coupon Barrier on a Coupon Observation Date or less than its Downside Threshold on the Final Valuation Date. Therefore it is more likely that you will not receive any Contingent Coupons and that you will suffer a significant loss on your investment at maturity.

In addition, movements in the prices of the Underlyings may be correlated or uncorrelated at different times during the term of the Notes, and such correlation (or lack thereof) could have an adverse effect on your return on the Notes. The correlation of a pair of Underlyings represents a statistical measurement of the degree to which the ratios of the returns of those Underlyings were similar to each other over a given period of time. The correlation between a pair of Underlyings is scaled from 1.0 to -1.0, with 1.0 indicating perfect positive correlation (i.e., the value of both Underlyings are increasing together or decreasing together and the ratio of their daily returns has been constant), 0 indicating no correlation (i.e., there is no statistical relationship between the daily returns of that pair of Underlyings) and -1.0 indicating perfect negative correlation (i.e., as the value of one Underlying increases, the value of the other Underlying decreases and the ratio of their daily returns has been constant).

The lower (or more negative) the correlation between two Underlyings, the less likely it is that those Underlyings will move in the same direction and, therefore, the greater the potential for one of those Underlyings to close below its Coupon Barrier or Downside Threshold on a Coupon Observation Date or the Final Valuation Date, respectively. This is because the less positively correlated a pair of Underlyings are, the greater the likelihood that at least one of the Underlyings will decrease in value. This results in a greater potential for a Contingent Coupon not to be paid during the term of the Notes and for a loss of principal at maturity. However, even if two Underlyings have a higher positive correlation, one or both of those Underlyings might close below its Coupon Barrier or Downside Threshold on a Coupon Observation Date or the Final Valuation Date, as both of those Underlyings may decrease in value together.

HSBC determines the Contingent Coupon Rate for the Notes based, in part, on the correlation among the Underlyings, calculated using internal models at the time the terms of the Notes are set. As discussed above, increased risk resulting from lower correlation will be reflected in a higher Contingent Coupon Rate than would be payable on notes that have a higher degree of correlation.

¨ Your Return Will Be Based on the Individual Return of Each Underlying — Unlike notes linked to a basket of underlyings, the Notes will be linked to the individual performance of each Underlying. Because the Notes are not linked to a basket, in which case the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the prices of the Underlyings to the same degree for each Underlying. The amount payable on the Notes, if any, depends on the performance of the Least Performing Underlying regardless of the performance of the other Underlying. You will bear the risk that either of the Underlyings will perform poorly.

¨ Limited Return on the Notes — The return potential of the Notes is limited to the Contingent Coupon Rate regardless of any appreciation of any Underlying. In addition, your total return on the Notes will vary based on the number of Coupon Observation Dates for which the Contingent Coupons are payable and may be less than the Contingent Coupon Rate, or even zero. Further, the return potential of the Notes is limited by the automatic call feature in that you will not receive any further payments after the Notes are called. Your Notes could be called as early as January 29, 2021, and your return could be minimal. If the Notes are not called, you may be exposed to the decline in the price of the Least Performing Underlying even though you cannot participate in any potential appreciation in the price of any Underlying. In addition, if the Notes have not been previously called and if the price of any Underlying is less than its Initial Price, as the Maturity Date approaches and the remaining number of Coupon Observation Dates decreases, the Notes are less likely to be automatically called, as there will be a shorter period of time remaining for the price of an Underlying to

8

increase to its Initial Price. As a result, the return on an investment in the Notes could be less than the return on a direct investment in securities represented by the Underlyings.

¨ No Assurance that the Return Strategy of the Notes Will Be Successful — While the Notes are structured to provide Contingent Coupons as long as the Official Closing Price of each Underlying on the relevant Coupon Observation Date does not decline below its Coupon Barrier, we cannot assure you of the economic environment during the term of the Notes, or at maturity. As a result, you may not receive a Contingent Coupon on any Coupon Payment Date, and you may lose some or all of your initial investment in the Notes.

¨ Lack of Liquidity — The Notes will not be listed on any securities exchange or quotation system. One of HSBC’s affiliates intends to offer to purchase the Notes in the secondary market, but is not required to do so and may cease any such market-making activities at any time without notice. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which one of HSBC’s affiliates is willing to buy the Notes, and therefore you may have to sell your Notes at a significant discount.

¨ An Underlying and Its Underlying Index Are Different – The performance of an Underlying may not exactly replicate the performance of its underlying index, because the Underlying will reflect transaction costs and fees that are not included in the calculation of its underlying index. It is also possible that an Underlying may not fully replicate or may in certain circumstances diverge significantly from the performance of its underlying index due to the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments contained in the Underlying or due to other circumstances. An Underlying may use futures contracts, options, swap agreements, currency forwards and repurchase agreements in seeking performance that corresponds to its underlying index and in managing cash flows.

¨ The Underlyings Are Subject to Management Risk – The Underlyings are not managed according to traditional methods of “active” investment management, which involve the buying and selling of securities based on economic, financial and market analysis and investment judgment. Instead, the Underlyings, utilizing a “passive” or indexing investment approach, attempt to approximate the investment performance of the Underlyings’ applicable underlying index by investing in a portfolio of securities that generally replicate its applicable underlying index. Therefore, unless a specific security is removed from its underlying index, the Underlyings generally would not sell a security because the security’s issuer was in financial trouble. In addition, the Underlyings are subject to the risk that the investment strategy of the Underlyings’ investment advisor may not produce the intended results.

¨ The Performance and Market Value of an Underlying During Periods of Market Volatility May Not Correlate with the Performance of its Underlying Index as well as the Net Asset Value per Share of that Underlying – During periods of market volatility, securities underlying an Underlying may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of that Underlying and the liquidity of the Underlying may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares of that Underlying. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of an Underlying. As a result, under these circumstances, the market value of shares of an Underlying may vary substantially from the net asset value per share of that Underlying. For all of the foregoing reasons, the performance of an Underlying may not correlate with the performance of its Underlying Index as well as the net asset value per share of the Underlying, which could materially and adversely affect the value of the Notes in the secondary market and/or reduce your payment at maturity.

¨ Owning the Notes Is Not the Same as Owning the Stocks Included in an Underlying — The return on your Notes may not reflect the return you would realize if you actually owned the stocks included in an Underlying. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the stocks included in any Underlying would have. Furthermore, an Underlying and the stocks included in an Underlying may appreciate substantially during the term of your Notes, and you will not participate in such appreciation.

¨ Potentially Inconsistent Research, Opinions or Recommendations by HSBC, UBS Financial Services Inc. or Their Respective Affiliates — HSBC, UBS Financial Services Inc., and their respective affiliates may publish research, express opinions or provide recommendations that are inconsistent with investing in or holding the Notes, and which may be revised at any time. Any such research, opinions or recommendations could affect the price of an Underlying, and therefore, the market value of the Notes.

¨ Potential HSBC and UBS Financial Services Inc. Impact on an Underlying — Trading or transactions by HSBC, UBS Financial Services Inc., or any of their respective affiliates in an Underlying or in futures, options, exchange-traded funds or other derivative products on an Underlying, may adversely affect the price of that Underlying, and, therefore, the market value of your Notes.

¨ Potential Conflicts of Interest — HSBC, UBS Financial Services Inc., or any of their respective affiliates may engage in business with the issuers of the stocks included in an Underlying, which may present a conflict between the obligations of HSBC or UBS Financial Services Inc., and you, as a holder of the Notes. HSBC, as the Calculation Agent, will determine on each applicable Coupon Observation Date whether the Contingent Coupon is to be paid, and whether the Notes are to be called, based on the Official Closing Price of each Underlying. The Calculation Agent can postpone the determination of the Official Closing Price on a Coupon Observation Date and the corresponding Coupon Payment Date or Call Settlement Date, as applicable, if a Market Disruption Event exists on that Coupon Observation Date. Furthermore, the Calculation Agent can postpone the determination of the Final Price and the Maturity Date if a Market Disruption Event occurs and is continuing on the Final Valuation Date.

¨ Economic and Market Factors Affecting the Terms and Market Price Prior to Maturity or Call — Because structured notes, including the Notes, can be thought of as having a debt and derivative component, factors that influence the values of debt instruments and options and other derivatives also affect the terms and features of the Notes at issuance and the market price of the Notes prior to maturity or call. These factors include the prices of the Underlyings; the volatility of the Underlyings; the dividend rate

9

paid on stocks included in the Underlyings; the time remaining to the maturity of the Notes; interest rates in the markets in general; geopolitical conditions and economic, financial, political, regulatory, judicial or other events; and the creditworthiness of HSBC. These and other factors are unpredictable and interrelated and may offset or magnify each other.

¨ The Notes Are Not Insured or Guaranteed by any Governmental Agency of the United States or any Other Jurisdiction —The Notes are not deposit liabilities or other obligations of a bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency or program of the United States or any other jurisdiction. An investment in the Notes is subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations as they become due, you may not receive any amount owed to you under the Notes and could lose your entire investment.

¨ The Amount Payable on the Notes Is Not Linked to the Prices of the Underlyings at Any Time Other Than on the Coupon Observation Dates, Including the Final Valuation Date — The return on the Notes will be based on the Official Closing Price of each Underlying on the Coupon Observation Dates, subject to postponement for non-trading days and certain Market Disruption Events. Even if the price of an Underlying appreciates prior to the applicable Call Observation Date or Coupon Observation Date but then drops on that day to a price that is less than the Initial Price or Coupon Barrier, the Notes will not be called, the Contingent Coupon may not be payable, and the return on the Notes will be less, and may be significantly less, than it would have been had the Notes been linked to the price of that Underlying prior to such decrease. Although the actual price of an Underlying on the Maturity Date or at other times during the term of the Notes may be higher than its Official Closing Price on any Coupon Observation Date, the return on the Notes will be based solely on the Official Closing Price of each Underlying on the applicable Coupon Observation Dates, including the Final Valuation Date.

¨ Small-Capitalization Companies Risk — The IWM tracks companies that may be considered small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the market price of the IWM may be more volatile than an investment in stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also generally more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded, making it difficult for the IWM to track them. In addition, small-capitalization companies are typically less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and fewer competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

¨ The Notes Are Subject to Emerging Markets Risk – An investment in the Notes will involve risks not generally associated with investments which have no emerging market component. In particular, many emerging nations are undergoing rapid change, involving the restructuring of economic, political, financial and legal systems. Regulatory and tax environments may be subject to change without review or appeal. Many emerging markets suffer from underdevelopment of capital markets and tax regulation. The risk of expropriation and nationalization remains a threat. Guarding against such risks is made more difficult by low levels of corporate disclosure and unreliability of economic and financial data.

¨ Risks Associated with Non-U.S. Companies – The price of the EEM depends upon the stocks of non-U.S. companies, and thus involves risks associated with the home countries of those non-U.S. companies. The prices of these non-U.S. stocks may be affected by political, economic, financial and social factors in the home country of each applicable company, including changes in that country's government, economic and fiscal policies, currency exchange laws or other laws or restrictions, which could affect the value of the securities. These foreign securities may have less liquidity and could be more volatile than many of the securities traded in U.S. or other securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may affect trading levels or prices and volumes in those markets. The other special risks associated with foreign securities may include, but are not limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; different accounting and disclosure standards; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of any Underlying and, as a result, the value of the Notes.

¨ The Prices of the EEM are Subject to Currency Exchange Risk – Because the price of the EEM are related to the U.S. dollar value of stocks underlying the relevant indices, holders of the Notes will be exposed to currency exchange rate risk with respect to each of the currencies in which such component securities trade. Exchange rate movements for a particular currency are volatile and are the result of numerous factors including the supply of, and the demand for, those currencies, as well as relevant government policy, intervention or actions, but are also influenced significantly from time to time by political or economic developments, and by macroeconomic factors and speculative actions related to the relevant region. An investor’s net exposure will depend on the extent to which the currencies of the component securities strengthen or weaken against the U.S. dollar and the relative weight of each currency. If, taking into account such weighting, the dollar strengthens against the currencies of the component securities represented in the relevant indices, the price of the EEM will be adversely affected and the payment at maturity on the Notes may be reduced.

Of particular importance to potential currency exchange risk are:

– existing and expected rates of inflation;

– existing and expected interest rate levels;

– the balance of payments; and

– the extent of governmental surpluses or deficits in the countries represented in the relevant indices and the United States.

10

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of various countries represented in the relevant indices and the United States and other countries important to international trade and finance.

¨ Changes Affecting an Underlying — The policies of an Underlying’s sponsor concerning additions, deletions and substitutions of the stocks included in that Underlying and the manner in which the sponsor takes account of certain changes affecting those stocks may adversely affect the price of that Underlying. The policies of a sponsor with respect to the calculation of the relevant Underlying could also adversely affect the price of that Underlying. A sponsor may discontinue or suspend calculation or dissemination of the relevant Underlying. Any such actions could have an adverse effect on the value of the Notes.

¨ Uncertain Tax Treatment — There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one reasonable approach, the Notes should be treated as contingent income-bearing pre-paid executory contracts with respect to the Underlyings. HSBC intends to treat the Notes consistent with this approach and pursuant to the terms of the Notes, you agree to treat the Notes under this approach for all U.S. federal income tax purposes. See “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated as Executory Contracts” in the accompanying prospectus supplement for the U.S. federal income tax considerations applicable to securities that are treated as contingent income-bearing pre-paid executory contracts.

In addition, the Notes are not intended for purchase by any investor that is not a United States person, as that term is defined for U.S. federal income tax purposes, and the underwriters will not make offers of the Notes to any such investor. If, however, a Note is transferred to a non-U.S. holder (as defined in the accompanying prospectus supplement) in the secondary market, because the tax treatment of the Contingent Coupons is unclear, such non-U.S. holder may be subject to 30% withholding tax applicable to any Contingent Coupon, subject to reduction or elimination by applicable treaty, unless income from such Contingent Coupon is effectively connected with your conduct of a trade or business within the United States. HSBC will not pay any additional amounts in respect of such withholding.

In Notice 2008-2, the Internal Revenue Service (“IRS”) and the Treasury Department requested comments as to whether the purchaser of an exchange traded note or pre-paid forward contract (which may include the Notes) should be required to accrue income during its term under a mark-to-market, accrual or other methodology, whether income and gain on such a note or contract should be ordinary or capital, and whether foreign holders should be subject to withholding tax on any deemed income accrual. Accordingly, it is possible that regulations or other guidance could provide that a U.S. holder (as defined in the accompanying prospectus supplement) of a Note is required to accrue income in respect of the Notes prior to the receipt of payments with respect to the Notes or their earlier sale. Moreover, it is possible that any such regulations or other guidance could treat all income and gain of a U.S. holder in respect of the Notes as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder of the Notes could be subject to U.S. withholding tax in respect of the Notes. It is unclear whether any regulations or other guidance would apply to the Notes (possibly on a retroactive basis). Prospective investors are urged to consult with their tax advisors regarding Notice 2008-2 and the possible effect to them of the issuance of regulations or other guidance that affects the U.S. federal income tax treatment of the Notes.

For a more complete discussion of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “What Are the Tax Consequences of the Notes?” herein and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

Hypothetical Scenario Analysis and Examples at Maturity

The scenario analysis and examples below are hypothetical and provided for illustrative purposes only. They do not purport to be representative of every possible scenario concerning increases or decreases in the price of any Underlying relative to its Initial Price. The hypothetical terms used below are not the actual terms that will apply to the Notes. The actual terms are indicated on the cover of this pricing supplement. We cannot predict the Final Price or the Official Closing Price of any Underlying on any Coupon Observation Date or Call Observation Date. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of any Underlying. The numbers appearing in the examples below may have been rounded for ease of analysis. The following scenario analysis and examples illustrate the Payment at Maturity or upon earlier automatic call per $10.00 Note on a hypothetical offering of the Notes, based on the following assumptions:

Investment term:	5 years (unless earlier called)
Initial Prices:	$100.00 for each Underlying
Contingent Coupon Rate:	6.00% per annum (or 1.50% per quarter)
Contingent Coupon:	$0.15 per quarter
Coupon Observation Dates:	Quarterly
Call Observation Dates:	Quarterly, commencing on January 29, 2021
Coupon Barriers:	$70.00 for each Underlying (70% of its Initial Price)
Downside Thresholds:	$70.00 for each Underlying (70% of its Initial Price)

Example 1 — Notes are Called on the First Call Observation Date, Which Corresponds to the Fourth Coupon Observation Date

Date	Official Closing Price	Payment (per Note)
First Coupon Observation Date	IWM: $105.00 (above Coupon Barrier and Initial Price) EEM: $115.00.00 (above Coupon Barrier and Initial Price)	$0.15 (Contingent Coupon) – Notes are not automatically called
Second and Third Coupon Observation Dates	Various (the Official Closing Price of at least one Underlying below Coupon Barrier; below Initial Price)	$0.00
Fourth Coupon Observation Date and First Call Observation Date	IWM: $110.00 (above Coupon Barrier and Initial Price) EEM: $120.00.00 (above Coupon Barrier and Initial Price)	$10.15 (Settlement Amount)
	Total Payment: $10.30 (3.00% return)

Since the Notes are called on the fourth Coupon Observation Date (which is the first Call Observation Date), HSBC will pay you on the Call Settlement Date a total of $10.15 per Note, reflecting your Principal Amount plus the applicable Contingent Coupon. When added to the Contingent Coupon payment of $0.15 received in respect of the first Coupon Observation Date, HSBC will have paid you a total of $10.30 per Note, for a 3.00% total return on the Notes. No further amount will be owed to you under the Notes.

Example 2 — Notes are NOT Called and the Final Price of Each Underlying Is at or Above Its Coupon Barrier and Downside Threshold

Date	Official Closing Price	Payment (per Note)
First Coupon Observation Date	IWM: $105.00 (above Coupon Barrier and Initial Price) EEM: $115.00.00 (above Coupon Barrier and Initial Price)	$0.15 (Contingent Coupon) – Notes are not automatically called
Second and Third Coupon Observation Dates	Various (the Official Closing Price of at least one Underlying below Coupon Barrier; below Initial Price)	$0.00
Fourth Coupon Observation Date (and first Call Observation Date)	IWM: $90.00 (at or above Coupon Barrier; below Initial Price) EEM: $120.00 (above Coupon Barrier and Initial Price)	$0.15 (Contingent Coupon) – Notes are not automatically called
Fifth through Nineteenth Coupon Observation Dates	Various (the Official Closing Price of at least one Underlying below Coupon Barrier; below Initial Price)	$0.00
Final Valuation Date	IWM: $95.00 (at or above Coupon Barrier and Downside Threshold; below Initial Price) EEM: $155.00 (above Coupon Barrier, Downside Threshold and Initial Price)	$10.15 (Payment at Maturity)
	Total Payment: $10.45 (4.50% return)

At maturity, HSBC will pay you a total of $10.15 per Note, reflecting your Principal Amount plus the applicable Contingent Coupon. When added to the Contingent Coupon payments of $0.15 received in respect of each of the first and fourth Coupon Observation Dates, HSBC will have paid you a total of $10.45 per Note, for a 4.50% total return on the Notes.

12

Example 3 — Notes are NOT Called and the Final Price of the Least Performing Underlying Is Below Its Coupon Barrier and Downside Threshold

Date	Official Closing Price	Payment (per Note)
First Coupon Observation Date	IWM: $105.00 (above Coupon Barrier and Initial Price) EEM: $115.00.00 (above Coupon Barrier and Initial Price)	$0.15 (Contingent Coupon) – Notes are not automatically called
Second and Third Coupon Observation Dates	Various (the Official Closing Price of at least one Underlying below Coupon Barrier; below Initial Price)	$0.00
Fourth Coupon Observation Date (and first Call Observation Date)	IWM: $90.00 (at or above Coupon Barrier; below Initial Price) EEM: $120.00 (above Coupon Barrier and Initial Price)	$0.15 (Contingent Coupon) – Notes are not automatically called
Fifth through Nineteenth Coupon Observation Dates	Various (the Official Closing Price of at least one Underlying below Coupon Barrier; below Initial Price)	$0.00
Final Valuation Date	IWM: $40.00 (below Coupon Barrier, Downside Threshold and Initial Price) EEM: $155.00 (above Coupon Barrier, Downside Threshold and Initial Price)	$10.00 × (1 + Underlying Return) =$10.00 × (1 + -60%) =$10.00 - $6.00 =$4.00 (Payment at Maturity)
	Total Payment $4.30 (-57.00% return)

Since the Notes are not called and the Final Price of the Least Performing Underlying is below its Downside Threshold, HSBC will pay you at maturity $4.00 per Note. In addition, the final Contingent Coupon will not be payable because the Final Price of the Least Performing Underlying is also below its Coupon Barrier. When added to the Contingent Coupon payments of $0.15 received in respect of each of the first and fourth Coupon Observation Dates, HSBC will have paid you $4.30 per Note, for a loss on the Notes of 57.00%.

Information About the Underlyings

The iShares^® Russell 2000 ETF

Description of the IWM

We have derived all information contained in this document regarding the iShares^® Russell 200 ETF (the “IWM”), including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by, iShares, Inc. (iShares). Neither we nor any of our affiliates has undertaken any independent review or due diligence of such information.

The IWM is an investment portfolio maintained and managed by iShares and advised by BlackRock Fund Advisors (“BFA”). iShares is a registered investment company that consists of numerous separate investment portfolios, including the IWM. The shares of the IWM are listed and trade on the NYSE Arca, Inc. under the ticker symbol “IWM.”

Information provided to or filed with the SEC by iShares pursuant to the Securities Act of 1933 and the Investment Company Act of 1940 can be located by reference to SEC file numbers 333-92935 and 811-09729, respectively, through the SEC’s website at http://www.sec.gov. Information from outside sources is not incorporated by reference in, and should not be considered a part of, this document. Neither we nor any of our affiliates has undertaken any independent review or due diligence of such information. In addition, information may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As a prospective purchaser, you should undertake an independent investigation of the IWM as in your judgment is appropriate to make an informed decision with respect to an investment linked to the IWM.

Investment Objective and Strategy

The IWM seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the small capitalization sector of the U.S. equity market as measured by the Russell 2000^® Index (the “RTY”). The RTY was developed by FTSE Russell (“Russell”) as an equity benchmark representing the approximately 2,000 smallest companies in the Russell 3000^® Index. The Russell 3000^® Index is composed of the 3,000 largest U.S. companies as determined by market capitalization and represents approximately 98% of the U.S. equity market. The returns of the IWM may be affected by certain management fees and other expenses, which are detailed in its prospectus.

Representative Sampling

The IWM pursues a “representative sampling” strategy in attempting to track the performance of the RTY, meaning the IWM invests in a representative sample of securities that collectively has an investment profile similar to the RTY. Securities selected are expected to have aggregate investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the RTY.

The IWM generally invests at least 90% of its assets in securities of the RTY and in depositary receipts representing securities of the RTY. The IWM may invest the remainder of its assets in certain futures, options and swap contracts, cash and cash equivalents, including money market funds advised by BFA or its affiliates, as well as in securities not included in the RTY, but which BFA believes will help the IWM track the RTY.

Correlation

The RTY is a theoretical financial calculation, while the IWM is an actual investment portfolio. The performance of the IWM and the RTY will vary somewhat due to fees and expenses, transaction costs, un-invested cash, timing variances, and actions taken by the fund to maintain certain regulatory or tax treatments among other causes. The divergence between IWM’s performance and the RTY is called “tracking error.” The divergence between IWM’s performance and the RTY is called “tracking error.” The IWM, using a representative sampling strategy, can be expected to have a greater tracking error than a fund using replication strategy. Replication is a strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the RTY.

Industry Concentration Policy

The IWM will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries only to approximately the same extent that the RTY is so concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Description of the Russell 2000^® Index

We have derived all information relating to the Russell 2000^® Index (the “RTY”), including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, Russell. Neither we nor any of our affiliates has undertaken any independent review or due diligence of such information. Russell has no obligation to continue to publish, and may discontinue the publication of, the RTY at any time.

General

The RTY is an index calculated, published, and disseminated by Russell, and measures the composite price performance of stocks of 2,000 companies determined by Russell to be part of the U.S. equity market. All 2,000 stocks are traded on a major U.S. exchange, and form a part of the Russell 3000^® Index. The Russell 3000^® Index is composed of the 3,000 largest U.S. companies as determined by market capitalization.

The RTY consists of the smallest 2,000 companies, by market capitalization, included in the Russell 3000^® Index. The RTY is designed to track the performance of the small capitalization segment of the U.S. equity market. The inception date of the RTY is January 1, 1984.Members of the RTY are determined each year during the annual reconstitution and are enhanced quarterly with the addition of initial public offerings (IPOs). The RTY is one of the Russell U.S. indices.

Defining Eligible Securities

All companies that are determined to be part of the U.S. equity market under Russell’s country-assignment methodology are included in the Russell U.S. indices. If a company is incorporated in, has a stated headquarters location in, and also trades in the same country (American Depositary Receipts and American Depositary Shares are not eligible), the company is assigned to the equity market of its country of incorporation. If any of the three do not match, Russell then defines three Home Country Indicators (“HCI”): country of Incorporation, country of headquarters, and country of the most liquid exchange as defined by two-year average daily dollar trading volume from all exchanges within a country. Using the HCIs, Russell cross-compares the primary location of the company’s assets with the three HCIs. If the primary location of the company’s assets matches any of the HCIs, then the company is assigned to its primary asset location. If there is insufficient information to determine the country in which the company’s assets are primarily located, Russell will use the

14

primary location of the company’s revenues for the same cross-comparison and will assign the company to the appropriate country in a similar fashion. Russell uses an average of two years of asset or revenue data for analysis to reduce potential turnover. If conclusive country details cannot be derived from assets or revenue, Russell assigns the company to the country where its headquarters are located unless the country is a benefit driven incorporation (“BDI”) country; in which case, the company will be assigned to the country of its most liquid stock exchange. Russell lists the following countries as BDIs: Anguilla, Antigua and Barbuda, Aruba, Bahamas, Barbados, Belize, Bermuda, Bonaire, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Curacao, Guernsey, Gibraltar, Isle of Man, Jersey, Liberia, Marshall Islands, Panama, Saba, Sint Eustatius, Sint Maarten, and Turks and Caicos Islands. For any companies incorporated or headquartered in a U.S. territory, including countries such as Puerto Rico, Guam, and U.S. Virgin Islands, a U.S. HCI is assigned. If a company is designated as a Chinese “N Share”, it will not be considered for inclusion within the Russell US Indexes. An “N Share” company is a company controlled by Mainland Chinese entities, companies or individuals, incorporated outside of China and traded on the New York Stock Exchange, the Nasdaq exchange, or the NYSE American with a majority of its revenue or assets derived from People’s Republic of China.

Preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights, installment receipts and trust receipts are not eligible for inclusion in the Russell U.S. Indices. All securities eligible for inclusion in Russell U.S. indices must trade on an eligible U.S. exchange. The eligible U.S. exchanges are: NYSE, NYSE American, Nasdaq and ARCA. Bulletin board, pink-sheets, and over-the-counter (“OTC”) traded securities are not eligible for inclusion, including securities for which prices are displayed on the FINRA ADF. Royalty trusts, U.S. limited liability companies, closed-end investment companies, blank check companies, special-purpose acquisition companies, and limited partnerships are also not eligible for inclusion in the Russell U.S. Indices. Business development companies, exchange traded funds and mutual funds are also excluded.

If an eligible company trades under multiple share classes, Russell will review each share class independently for U.S. index inclusion. Stocks must trade at or above $1.00 (on its primary exchange) on the last trading day in May of each year to be eligible for inclusion in the RTY during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing member’s closing price is less than $1.00 on the last day of May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the month of May is equal to or greater than $1.00. If an existing index member does not trade on the last trading day in May, it must price at $1.00 or above on another eligible U.S. exchange to remain eligible. A stock added during the quarterly IPOs process is considered a new index addition and therefore must have a close price on its primary exchange at or above $1.00 on the last day of the IPO eligibility period in order to qualify for index inclusion. Companies with a total market capitalization of less than $30 million are not eligible for inclusion in the Russell U.S. indices. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible for the Russell U.S. indices.

Annual Reconstitution

Annual reconstitution is the process by which all Russell Indexes are completely rebuilt. Reconstitution is a vital part of the creation of a benchmark which accurately represents a particular market segment. Companies may get bigger or smaller over time, or periodically undergo changes in their style characteristics. Reconstitution ensures that companies continue to be correctly represented in the appropriate Russell indices.

On the rank day in May each year (timetable is announced each spring), all eligible securities are ranked by their total market capitalization. Total market capitalization is determined by multiplying total outstanding shares by the last price traded on the primary exchange on the rank day in May. All share classes for a company, including unlisted shares, are aggregated and considered total shares outstanding.

Reconstitution occurs on the last Friday in June. However, at times this date is too proximal to exchange closures and abbreviated exchange trading schedules when market liquidity is exceptionally low. In order to ensure proper liquidity in the markets, when the last Friday in June falls on the 29th or 30th, reconstitution will occur on the preceding Friday.

Eligible IPOs are added to the Russell U.S. indices quarterly to ensure that new additions to the institutional investing opportunity set are reflected in the representative indices. Russell focuses on IPOs each quarter because it is important to reflect market additions between reconstitution periods. Companies filing an initial public offering registration statement (or the local equivalent when outside the United States) and listing with the same quarter on an eligible U.S. exchange are reviewed for eligibility regardless of previous trading activity (exceptional or unique events may induce extraordinary treatment which will be communicated appropriately); a one month window is used to ensure that companies submitting the requisite filings just outside of the quarter are not excluded from eligibility. Companies currently trading on foreign exchanges or OTC markets will be reviewed for eligibility if: (1) the company files an initial public offering statement for an eligible U.S. exchange; (2) the offering is announced to the market and confirmed by Russell’s vendors as an IPO; and (3) the security is not currently a member of the Russell Global Index (eligibility and country assignment are reviewed at reconstitution).

Capitalization Adjustments

After membership is determined, a security’s shares are adjusted to include only those shares available to the public, which is often referred to as “free float.” The purpose of this adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set. Stocks are weighted in the Russell U.S. indices by their available (also called “float-adjusted”) market capitalization, which is calculated by multiplying the primary closing price by the available shares. Adjustments to shares are reviewed at reconstitution, during quarterly update cycles, and for corporate actions such as mergers.

Certain types of shares are restricted and removed from total market capitalization to arrive at free float or available market capitalization, such as shares directly owned by State, Regional, Municipal and Local governments (excluding shares held by independently managed pension schemes for governments), shares held by directors, senior executives and managers of the company, and by their family and direct relations, and by companies with which they are affiliated, shares subject to a lock-in clause, and shares subject to on-going contractual agreements (such as swaps), et cetera.

Corporate Action-Driven Changes

Russell defines a corporate action as an action on shareholders with a prescribed ex-date (e.g., rights issue, special dividend, stock split). The share price and indexes in which the company is included will be subject to an adjustment on the ex-date. This is a mandatory event. Russell defines a corporate event as a reaction to company news (event) that might impact the index depending on the index rules. Russell applies corporate actions and events to its indexes on a daily basis. Depending upon the time an action is determined to be final, Russell will either (1) apply the action before the open on the ex-date, or (2) apply the action providing appropriate notice if it is deemed to be “actionable” for passive index managers.

For merger and spin-off transactions that are effective between rank day in May and the Friday prior to annual reconstitution in June, the market capitalizations of the impacted securities are recalculated and membership is reevaluated as of the effective date of the corporate action. For corporate events that occur during the final week of reconstitution (during which reconstitution is finalized Friday after U.S. market close), market capitalizations and memberships will not be reevaluated. Non index members that have been considered ineligible as of rank day will not be reevaluated in the event of a subsequent corporate action that occurs between rank day and the reconstitution effective date.

If a company distributes shares of an additional share class to its existing shareholders through a mandatory corporate action, Russell evaluates the additional share class for separate index membership. The new share class will be deemed eligible if the market capitalization of the distributed shares meets minimum

15

size requirement (above the minimum market capitalization breakpoint defined as the smallest member of the Russell 3000E Index from previous rebalance, adjusted for performance to date.) Index membership of additional share classes that are added due to corporate actions will mirror that of the pricing vehicle, as will style and stability probabilities. If the distributed shares of an additional share class do not meet eligibility requirements, they will not be added to the index (the distributed shares may be added to the index temporarily until they are settled and listed to enable index replication).

“No Replacement” Rule: Securities that leave a Russell U.S. index for any reason (e.g., mergers, acquisitions or other similar corporate activity) are not replaced. Thus, the number of securities in a Russell U.S. index over the year will fluctuate according to corporate activity.

To maintain representativeness and maximize the available investment opportunity for index managers, the Russell U.S. indices are reviewed quarterly for updates to shares outstanding and to free floats used within the index calculation. The changes are implemented quarterly, on the third Friday of the month (after the close). The June reconstitution will continue to be implemented on the last Friday of June (unless the last Friday occurs on the 29th or 30th, when reconstitution will occur on the Friday prior).

Correlation of the Underlyings

The following graph sets forth the historical performances of the iShares^® Russell 2000 ETF and iShares^® MSCI Emerging Markets ETF from January 29, 2010 through January 29, 2020, based on the daily Official Closing Prices of the Underlyings. For comparison purposes, each Underlying has been normalized to have a closing price of 100.00 on January 29, 2010 by dividing the Official Closing Price of that Underlying on each day by the Official Closing Price of that Underlying on January 29, 2010 and multiplying by 100.00.

We obtained the Official Closing Prices used to determine the normalized closing prices set forth below from Bloomberg, without independent verification. Historical performance of the Underlyings should not be taken as an indication of future performance. Future performance of the Underlyings may differ significantly from historical performance, and no assurance can be given as to the Official Closing Prices of the Underlyings during the term of the Notes, including on any Coupon Observation Date or Call Observation Date, or on the Final Valuation Date. We cannot give you assurance that the performances of the Underlyings will result in the return of any of the Principal Amount.

Historical Performance of the iShares^® Russell 2000 ETF and iShares^® MSCI Emerging Markets ETF

PAST PERFORMANCE OF THE UNDERLYINGS IS NOT INDICATIVE OF FUTURE RESULTS.

The closer the relationship of the daily returns of the Underlyings over a given period, the more positively correlated those Underlyings are. The graph above illustrates the historical performance of each of the Underlyings relative to the other Underlying over the time period shown and provides an indication of how close the relative performance of the daily returns of one Underlying has historically been to another. For additional information, see the information set forth above under “Key Risks –Because the Notes Are Linked to the Performance of More Than One Underlying, There Is a Greater Risk of Contingent Coupons Not Being Paid and of You Sustaining a Significant Loss on Your Investment.”

The lower (or more negative) the correlation between two Underlyings, the less likely it is that those Underlyings will move in the same direction and, therefore, the greater the potential for one of those Underlyings to close below its Coupon Barrier or Downside Threshold on a Coupon Observation Date or the Final Valuation Date, respectively. This is because the less positively correlated a pair of Underlyings are, the greater the likelihood that at least one of the Underlyings will decrease in value. This results in a greater potential for a Contingent Coupon not to be paid during the term of the Notes and for a loss of principal at maturity. However, even if two Underlyings have a higher positive correlation, one or both of those Underlyings might close below its Coupon Barrier or Downside Threshold on a Coupon Observation Date or the Final Valuation Date, as both of those Underlyings may decrease in value together.

The terms of the Notes will be based, in part, on the correlation among the Underlyings, calculated using internal models at the time the terms of the Notes are set. As discussed above, increased risk resulting from lower correlation will be reflected in a higher Contingent Coupon Rate than would be payable on notes that have a higher degree of correlation.

What Are the Tax Consequences of the Notes?

You should carefully consider, among other things, the matters set forth in the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement. The following discussion summarizes the U.S. federal income tax consequences of the purchase, beneficial ownership, and disposition of the Notes. This summary supplements the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement and supersedes it to the extent inconsistent therewith.

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes. Under one reasonable approach, the Notes should be treated as contingent income-bearing pre-paid executory contracts with respect to the Underlyings. HSBC intends to treat the Notes consistent with this approach, and pursuant to the terms of the Notes, you agree to treat the Notes under this approach for all U.S. federal income tax purposes. Subject to certain limitations described in the accompanying prospectus supplement, and based on certain factual representations received from HSBC, in the opinion of HSBC’s special U.S. tax counsel, Mayer Brown LLP, it is reasonable to treat the Notes in accordance with this approach. Pursuant to this approach, HSBC intends to treat any gain or loss upon maturity or an earlier sale, exchange or call as capital gain or loss in an amount equal to the difference between the amount you receive at such time (other than with respect to a Contingent Coupon) and your tax basis in the Note. Any such gain or loss will be long-term capital gain or loss if you have held the Note for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a Note generally will equal your cost of the Note. In addition, the tax treatment of the Contingent Coupons is unclear. Although the tax treatment of the Contingent Coupons is unclear, HSBC intends to treat any Contingent Coupon paid by HSBC, including on the Maturity Date or upon automatic call, as ordinary income includible in income by you at the time it accrues or is received in accordance with your normal method of accounting for U.S. federal income tax purposes. See “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated Executory Contracts” in the accompanying prospectus supplement for the U.S. federal income tax considerations applicable to securities that are treated as contingent income-bearing pre-paid executory contracts.

The Notes are not intended for purchase by any investor that is not a United States person, as that term is defined for U.S. federal income tax purposes, and the underwriters will not make offers of the Notes to any such investor. If, however, a Note is transferred to a non-U.S. holder in the secondary market, because the tax treatment of the Contingent Coupons is uncertain, the entire amount of the Contingent Coupons will be subject to U.S. federal income tax withholding at a 30% rate (or at a lower rate under an applicable income tax treaty), unless the income from such Contingent Coupon is effectively connected with your conduct of a trade or business within the United States. We will not pay any additional amounts in respect of such withholding. In order to claim an exemption from or a reduction in the 30% withholding tax, a non-U.S. holder of the Notes must comply with certification requirements to establish that it is not a U.S. person and is eligible for a reduction of, or an exemption from, withholding under an applicable tax treaty. If you are a non-U.S. holder, you should consult your tax advisors regarding the tax treatment of the Notes, including the possibility of obtaining a refund of any withholding tax and the certification requirement described above.

Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes, other characterizations and treatments are possible and the timing and character of income in respect of the Notes might differ materially and adversely from the treatment described above. For example, the Notes could be treated as debt instruments that are “contingent payment debt instruments” for U.S. federal income tax purposes, subject to the treatment described under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes — Contingent Notes” in the accompanying prospectus supplement.

In Notice 2008-2, the IRS and the Treasury Department requested comments as to whether the purchaser of an exchange traded note or pre-paid forward contract (which may include the Notes) should be required to accrue income during its term under a mark-to-market, accrual or other methodology, whether income and gain on such a note or contract should be ordinary or capital, and whether foreign holders should be subject to withholding tax on any deemed income accrual. Accordingly, it is possible that regulations or other guidance could provide that a U.S. holder of a Note is required to accrue income in respect of the Notes prior to the receipt of payments with respect to the Notes or their earlier sale. Moreover, it is possible that any such regulations or other guidance could treat all income and gain of a U.S. holder in respect of the Notes as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder of the Notes could be subject to U.S. withholding tax in respect of the Notes. It is unclear whether any regulations or other guidance would apply to the Notes (possibly on a retroactive basis). Prospective investors are urged to consult with their tax advisors regarding Notice 2008-2 and the possible effect to them of the issuance of regulations or other guidance that affects the U.S. federal income tax treatment of the Notes.

We will not attempt to ascertain whether the Underlyings or any of the entities whose stock is included in the Underlyings would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the Underlyings or entities whose stock is included in the Underlyings were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the Underlyings or entities whose stock is included in the Underlyings and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Underlyings is or becomes a PFIC or USRPHC.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, Internal Revenue Service guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2023. Based on the Issuer’s determination that the Notes are not “delta-one”

19

instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Underlyings or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the Underlyings or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

PROSPECTIVE PURCHASERS OF THE NOTES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE U.S. FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES.

20

Events of Default and Acceleration

If the Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Notes, the Calculation Agent will determine the accelerated payment due and payable at maturity in the same general manner as described herein, except that the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for the purposes of determining the Final Price and if a Contingent Coupon is payable. If a Market Disruption Event exists with respect to an Underlying on that scheduled trading day, then the accelerated Final Valuation Date for that Underlying will be postponed for up to five scheduled trading days (in the same manner used for postponing the originally scheduled Final Valuation Date). The accelerated Maturity Date will also be postponed by an equal number of business days. For the avoidance of doubt, if no Market Disruption Event exists with respect to an Underlying on the scheduled trading day preceding the date of acceleration, the determination of such Underlying’s Underlying Return will be made on such date, irrespective of the existence of a Market Disruption Event with respect to any other Underlying occurring on such date.

If the Notes have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the Notes. For more information, see “Description of Debt Securities — Senior Debt Securities — Events of Default” in the accompanying prospectus.

Supplemental Plan of Distribution (Conflicts of Interest)

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc., an affiliate of HSBC, will purchase the Notes from HSBC for distribution to UBS Financial Services Inc. (the “Agent”). HSBC Securities (USA) Inc. has agreed to sell to the Agent, and the Agent has agreed to purchase, all of the Notes at the price to public less the underwriting discount indicated on the cover hereof. HSBC has agreed to indemnify the Agent against liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Agent may be required to make relating to these liabilities as described in the prospectus supplement and the prospectus. The Agent may allow a concession to its affiliates not in excess of the underwriting discount set forth on the cover hereof.

Subject to regulatory constraints, HSBC USA Inc. (or an affiliate thereof) intends to offer to purchase the Notes in the secondary market, but is not required to do so and may cease making such offers at any time. HSBC or its affiliate will enter into swap agreements or related hedge transactions with one of its other affiliates or unaffiliated counterparties, which may include UBS Financial Services Inc., in connection with the sale of the Notes and UBS Financial Services Inc. and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use this pricing supplement in market-making transactions after the initial sale of the Notes, but is under no obligation to make a market in the Notes and may discontinue any market-making activities at any time without notice.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-61 in the accompanying prospectus supplement.

Validity of the Notes

In the opinion of Mayer Brown LLP, as counsel to the Issuer, when this pricing supplement has been attached to, and duly notated on, the master note that represents the Notes pursuant to the Senior Indenture referred to in the prospectus supplement dated February 26, 2018, and issued and paid for as contemplated herein, the Notes offered by this pricing supplement will be valid, binding and enforceable obligations of the Issuer, entitled to the benefits of the Senior Indenture, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith). This opinion is given as of the date hereof and is limited to the laws of the State of New York, the Maryland General Corporation Law (including the statutory provisions, all applicable provisions of the Maryland Constitution and the reported judicial decisions interpreting the foregoing) and the federal laws of the United States of America. This opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the Senior Indenture and the genuineness of signatures and to such counsel’s reliance on the Issuer and other sources as to certain factual matters, all as stated in the legal opinion dated March 1, 2018, which has been filed as Exhibit 5.4 to the Issuer’s registration statement on Form S-3 dated February 26, 2018.
