HSBC USA Inc. Trigger GEARS

Linked to the iShares^® MSCI EAFE ETF due on or about May 17, 2021

Investment Description

These Trigger GEARS (the “Securities”) are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”) with returns linked to the performance of the iShares^® MSCI EAFE ETF (the “Underlying Index Fund”). The Securities will rank equally with all of our other unsecured and unsubordinated debt obligations. If the Underlying Index Fund Return is greater than zero, HSBC will repay the Principal Amount at maturity plus a return equal to the product of (i) the Principal Amount multiplied by (ii) the Underlying Index Fund Return multiplied by the Upside Gearing of between 1.75 and 1.78 (the actual Upside Gearing will be determined on the Trade Date). If the Underlying Index Fund Return is less than or equal to zero, HSBC will either repay the full Principal Amount at maturity or, if the Final Price is less than the Downside Threshold, HSBC will pay less than the full Principal Amount at maturity, if anything, resulting in a loss of principal that is proportionate to the negative Underlying Index Fund Return. Investing in the Securities involves significant risks. You will not receive interest or dividend payments during the term of the Securities. You may lose some or all of your Principal Amount. The contingent repayment of principal applies only if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal at maturity, 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 Securities and you could lose your entire investment.

Features

¨Enhanced Growth Potential: If the Underlying Index Fund Return is greater than zero, HSBC will repay the Principal Amount at maturity plus a return equal to the Underlying Index Fund Return multiplied by the Upside Gearing. If the Underlying Index Fund Return is less than zero, investors may be exposed to the negative Underlying Index Fund Return at maturity.

¨Contingent Repayment of Principal at Maturity: If the Underlying Index Fund Return is equal to or less than zero and the Final Price is not less than the Downside Threshold, HSBC will repay the Principal Amount at maturity. However, if the Final Price is less than the Downside Threshold, HSBC will pay less than the full Principal Amount, if anything, resulting in a loss of principal that is proportionate to the negative Underlying Index Fund Return. The contingent repayment of principal applies only if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of HSBC.

Investor Suitability

The Securities may be suitable for you if: ¨ You fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ¨   You can tolerate a loss of all or a substantial portion of your Principal Amount and are willing to make an investment that may have the same downside market risk as the Underlying Index Fund. ¨   You believe the Underlying Index Fund will appreciate over the term of the Securities and you would be willing to invest in the Securities if the Upside Gearing was set equal to the bottom of the range indicated on the cover hereof (the actual Upside Gearing will be set on the Trade Date). ¨   You understand and accept the risks associated with the Underlying Index Fund. See “Key Risks” beginning on page 6 of this document for additional information. ¨   You are willing to accept the risk and return profile of the Securities versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating. ¨   You do not seek current income from your investment and are willing to forgo dividends paid on the Underlying Index Fund or the stocks included in the Underlying Index Fund. ¨   You seek an investment with returns based on the performance of foreign developed market companies. ¨   You are willing to hold the Securities to maturity and accept that there may be little or no secondary market for the Securities. ¨   You are willing to assume the credit risk of HSBC, as Issuer of the Securities, and understand that if HSBC defaults on its obligations, you may not receive any amounts due to you, including any repayment of principal.

The Securities may not be suitable for you if: ¨   You do not fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ¨   You cannot tolerate a loss of all or a substantial portion of your Principal Amount, and you are not willing to make an investment that may have the same downside market risk as the Underlying Index Fund. ¨   You believe that the price of the Underlying Index Fund will decline during the term of the Securities and is likely to close below the Downside Threshold on the Final Valuation Date. ¨   You would be unwilling to invest in the Securities if the Upside Gearing was set equal to the bottom of the range indicated on the cover hereof (the actual Upside Gearing will be set on the Trade Date). ¨   You do not understand or accept the risks associated with the Underlying Index Fund. See “Key Risks” beginning on page 6 of this document for additional information. ¨   You prefer the lower risk, and therefore accept the potentially lower returns, of conventional debt securities with comparable maturities issued by HSBC or another issuer with a similar credit rating. ¨   You seek current income from your investment or prefer to receive the dividends paid on the Underlying Index Fund or the stocks included in the Underlying Index Fund. ¨   You do not seek an investment with returns based on the performance of foreign developed market companies. ¨   You are unable or unwilling to hold the Securities to maturity or you seek an investment for which there will be an active secondary market. ¨   You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Securities, for any payment on the Securities, including any repayment of principal.

The suitability considerations identified above are not exhaustive. Whether or not the Securities are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the suitability of an investment in the Securities in light of your particular circumstances. You should also carefully review “Key Risks” beginning on page 6 of this free writing prospectus and “Risk Factors” beginning on page S-1 of the ETF Underlying Supplement and beginning on page S-1 of the prospectus supplement.

Investment Timeline

The Initial Price and the Downside Threshold are determined and the Upside Gearing is set.

The Final Price and Underlying Index Fund Return are determined on the Final Valuation Date. If the Underlying Index Fund Return is greater than zero, HSBC will pay you a cash payment per Security that provides you with the $10 Principal Amount plus a return equal to the product of (i) the Principal Amount multiplied by (ii) the Underlying Index Fund Return multiplied by the Upside Gearing, calculated as follows: $10 + [$10 × (Underlying Index Fund Return × Upside Gearing)]. If the Underlying Index Fund Return is less than or equal to zero and the Final Price is greater than or equal to the Downside Threshold on the Final Valuation Date, HSBC will pay you a cash payment of $10 per $10 Security. If the Final Price is less than the Downside Threshold on the Final Valuation Date, HSBC will pay you a cash payment at maturity that will be less than the Principal Amount of $10 per Security, resulting in a loss of principal that is proportionate to the negative Underlying Index Fund Return, equal to: $10 + ($10 × Underlying Index Fund Return). Under these circumstances, you will lose a significant portion, and could lose all, of your Principal Amount.

Key Risks

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

¨ Risk of Loss at Maturity – The Securities differ from ordinary debt securities in that HSBC will not necessarily pay the full Principal Amount of the Securities at maturity. The return on the Securities at maturity is linked to the performance of the Underlying Index Fund and will depend on whether, and to the extent which, the Underlying Index Fund Return is positive or negative and if the Underlying Index Fund Return is negative, whether the Final Price is below the Downside Threshold. If the Final Price is below the Downside Threshold, you will be fully exposed to any negative Underlying Index Fund Return and HSBC will pay you less than the Principal Amount at maturity, if anything, resulting in a loss of principal that is proportionate to the decline in the Final Price as compared to the Initial Price. Under these circumstances, you will lose a significant portion, and could lose all, of the Principal Amount.

¨ The Contingent Repayment of Principal Applies Only if You Hold the Securities to Maturity – You should be willing to hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, you may have to sell them at a loss even if the share price of the Underlying Index Fund is above the Downside Threshold.

¨ The Upside Gearing Applies Only if You Hold the Securities to Maturity – You should be willing to hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, the price you receive will likely not reflect the full economic value of the Upside Gearing or the Securities themselves, and the return you realize may be less than the return of the Underlying Index Fund, even if that return is positive. You can receive the full benefit of the Upside Gearing from HSBC only if you hold your Securities to maturity.

¨ The Securities Are Subject to the Credit Risk of the Issuer –The Securities are senior unsecured debt obligations of the Issuer, 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 Securities 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 Securities, including any repayment of principal at maturity, 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 Securities 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 Securities and you could lose your entire investment.

¨ The Estimated Initial Value of the Securities, Which Will Be Determined by Us on the Trade Date, Will Be Less than the Price to Public and May Differ from the Market Value of the Securities in the Secondary Market, if Any – The Estimated Initial Value of the Securities will be calculated by us on the Trade Date and will be less than the price to public. The Estimated Initial Value will reflect 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 Securities. 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 Securities may be lower if it were based on the levels 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 Securities to be more favorable to you. We will determine the value of the embedded derivatives in the Securities 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 Securities 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 Securities in the secondary market (if any exists) at any time.

¨ The Price of Your Securities 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 Securities and the costs associated with structuring and hedging our obligations under the Securities. 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 Securities in the secondary market, if any, the price you would receive for your Securities 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 Securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the price of the Underlying Index Fund and changes in market conditions, and cannot be predicted with accuracy. The Securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Securities to maturity. Any sale of the Securities prior to maturity could result in a loss to you.

¨ If One of Our Affiliates Were to Repurchase Your Securities Immediately After the Settlement Date, the Price You Receive May Be Higher than the Estimated Initial Value of the Securities – 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 Securities in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed the Estimated Initial Value on the Trade Date for a temporary period expected to be approximately 12 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 Securities and other costs in connection with the Securities that we will no longer expect to incur over the term of the Securities. 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 Securities and any agreement we may have with the distributors of the Securities. The amount of our estimated costs which we effectively reimburse to investors in this way

6

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 Securities based on changes in market conditions and other factors that cannot be predicted.

¨ No Interest Payments – HSBC will not make any interest payments with respect to the Securities.

¨ Owning the Securities Is Not the Same as Owning the Underlying Index Fund or the Stocks Comprising the Underlying Index Fund – The return on your Securities may not reflect the return you would realize if you actually owned the Underlying Index Fund or the stocks included in the Underlying Index Fund. As a holder of the Securities, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the stocks included in the Underlying Index Fund would have. The Underlying Index Fund Return excludes any cash dividend payments paid on the securities held by the Underlying Index Fund.

¨ The Securities Are Not Insured or Guaranteed by any Governmental Agency of the United States or any Other Jurisdiction – The Securities 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 Securities is subject to the credit risk of HSBC, and in the event HSBC is unable to pay its obligations when due, you may not receive any amounts owed to you under the Securities and you could lose your entire investment.

¨ Lack of Liquidity – The Securities will not be listed on any securities exchange or quotation system. One of our affiliates may offer to repurchase the Securities 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 Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which one of our affiliates is willing to buy the Securities. This price, if any, will exclude any fees or commissions paid when the Securities were purchased and therefore will generally be lower than such purchase price.

¨ There Is Limited Anti-Dilution Protection – For certain events affecting the Underlying Index Fund, such as stock splits or extraordinary dividends, the Calculation Agent may make adjustments to the Final Price which may affect your Payment at Maturity. However, the Calculation Agent is not required to make an adjustment for every corporate action that affects the Underlying Index Fund. If an event occurs that does not require the Calculation Agent to adjust the Final Price, the market price of the Securities and the Payment at Maturity may be materially and adversely affected.

¨ An Underlying Index Fund and Its Underlying Index Are Different – The performance of an Underlying Index Fund may not exactly replicate the performance of its underlying index, because the Underlying Index Fund will reflect transaction costs and fees that are not included in the calculation of its underlying index. It is also possible that an Underlying Index Fund 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 Index Fund or due to other circumstances. An Underlying Index Fund 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 Performance and Market Value of the Underlying Index Fund 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 the Underlying Index Fund – During periods of market volatility, securities underlying the Underlying Index Fund may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of the Underlying Index Fund and the liquidity of the Underlying Index Fund may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares of the Underlying Index Fund. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the Underlying Index Fund. As a result, under these circumstances, the market value of shares of the Underlying Index Fund may vary substantially from the net asset value per share of the Underlying Index Fund. For all of the foregoing reasons, the performance of the Underlying Index Fund may not correlate with the performance of the Underlying Index as well as the net asset value per share of the Underlying Index Fund, which could materially and adversely affect the value of the Securities in the secondary market and/or reduce your payment at maturity.

¨ The Probability that the Underlying Index Fund Will Fall Below the Downside Threshold on the Final Valuation Date Will Depend on the Volatility of the Underlying Index Fund – “Volatility" refers to the frequency and magnitude of changes in the price of the Underlying Index Fund. Greater expected volatility with respect to the Underlying Index Fund reflects a higher expectation as of the Trade Date that the Underlying Index Fund could close below its Downside Threshold on the Final Valuation Date, resulting in the loss of some or all of your investment. However, an index fund's volatility can change significantly over the term of the Securities. The level of the Underlying Index Fund could fall sharply, which could result in a significant loss of principal.

¨ The Underlying Index Fund Is Subject to Management Risk – The Underlying Index Fund is 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 Underlying Index Fund, utilizing a ‘‘passive’’ or indexing investment approach, attempts to approximate the investment performance of the Underlying Index Fund’s underlying index by investing in a portfolio of securities that generally replicate its underlying index. Therefore, unless a specific security is removed from its underlying index, the Underlying Index Fund generally would not sell a security because the security’s issuer was in financial trouble. In addition, the Underlying Index Fund is subject to the risk that the investment strategy of the Underlying Index Fund’s investment advisor may not produce the intended results.

¨ Potential Conflicts of Interest – HSBC, UBS Financial Services Inc., or any of our or their respective affiliates may engage in business with the issuers of the stocks comprising the Underlying Index Fund, which could affect the price of such stocks or the price of the Underlying Index Fund and thus, may present a conflict between the obligations of HSBC and you, as a holder of the

7

Securities. Additionally, potential conflicts of interest may exist between the Calculation Agent, which may be HSBC or any of its affiliates, and you with respect to certain determinations and judgments that the Calculation Agent must make, which include determining the Payment at Maturity based on the Final Price as well as whether to 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.

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

¨ The Amount Payable on the Securities Is Not Linked to the Price of the Underlying Index Fund at any Time Other than on the Final Valuation Date – The Final Price will be based on the Official Closing Price of the Underlying Index Fund on the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the price of the Underlying Index Fund appreciates prior to the Final Valuation Date but then decreases on the Final Valuation Date to a price that is below the Downside Threshold, the Payment at Maturity will be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the price of the Underlying Index Fund prior to such decrease. Although the actual price of the Underlying Index Fund on the Maturity Date or at other times during the term of the Securities may be higher than the Final Price, the Payment at Maturity will be based solely on the Official Closing Price of the Underlying Index Fund on the Final Valuation Date.

¨ Risks Associated with Non-U.S. Companies – The price of the Underlying Index Fund 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 the Underlying Index Fund and, as a result, the value of the Securities.

¨ The Price of the Underlying Index Funds is Subject to Currency Exchange Risk – Because the price of the Underlying Index Fund is related to the U.S. dollar value of stocks underlying the MSCI EAFE Index, holders of the Securities 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 MSCI EAFE Index, the price of the Underlying Index Fund will be adversely affected and the payment at maturity on the Securities 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 MSCI EAFE Index and the United States.

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 MSCI EAFE Index and the United States and other countries important to international trade and finance.

¨ Economic and Market Factors Affecting the Terms and Market Price Prior to Maturity – Because structured notes, including the Securities, can be thought of as having a debt and derivative component, factors that influence the values of debt instruments and options and other derivatives will also affect the terms and features of the Securities at issuance and the market price of the Securities prior to maturity. These factors include the price of the Underlying Index Fund; the volatility of the stocks held by the Underlying Index Fund; the dividend rate paid on stocks held by the Underlying Index Fund; the time remaining to the maturity of the Securities; 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.

¨ Potential HSBC and UBS Impact on Price –Trading or transactions by HSBC, UBS Financial Services Inc. or any of their respective affiliates in shares of the Underlying Index Fund, the stocks comprising the Underlying Index Fund or in futures, options, exchange-traded funds or other derivative products on these securities, may adversely affect the market value of the stocks comprising the Underlying Index Fund, the price of the Underlying Index Fund, and, therefore, the market value of your Securities.

¨ Uncertain Tax Treatment – Significant aspects of the tax treatment of the Securities are uncertain. You should consult your tax advisor about your own tax situation. See “What Are the Tax Consequences of the Securities?” beginning on page 11 of this free writing prospectus and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

Scenario Analysis and Examples at Maturity

The scenario analysis and examples below are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the price of the Underlying Index Fund relative to the Initial Price. We cannot predict the Final Price. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Underlying Index Fund. The numbers appearing in the examples below have been rounded for ease of analysis. The following scenario analysis and examples illustrate the Payment at Maturity for a $10.00 Security on a hypothetical offering of the Securities, with the following assumptions^*:

Investment term:	Five years
Hypothetical Initial Price:	$60.00
Hypothetical Downside Threshold:	$45.00 (75.00% of the hypothetical Initial Price)
Hypothetical Upside Gearing:	1.75 (the low end of the range of 1.75 to 1.78)

^* The actual Initial Price, Downside Threshold and Upside Gearing for the Securities will be determined on the Trade Date.

Example 1— The price of the Underlying Index Fund increases from an Initial Price of $60.00 to a Final Price of $66.00. The Underlying Index Fund Return is greater than zero and expressed as a formula:

Underlying Index Fund Return = ($66.00 - $60.00) / $60.00 = 10.00%

Payment at Maturity = $10 + [$10 × (10.00% × 1.75)] = $11.75

Because the Underlying Index Fund Return is equal to 10.00%, the Payment at Maturity is equal to $11.75 per $10.00 Principal Amount of Securities, and the return on the Securities is 17.50%.

Example 2— The Final Price is equal to an Initial Price of $60.00. The Underlying Index Fund Return is zero and expressed as a formula:

Underlying Index Fund Return = ($60.00 - $60.00) / $60.00 = 0.00%

Payment at Maturity = $10.00

Because the Underlying Index Fund Return is zero, the Payment at Maturity per Security is equal to the original $10.00 Principal Amount per Security (a return of zero percent).

Example 3— The price of the Underlying Index Fund decreases from an Initial Price of $60.00 to a Final Price of $51.00. The Underlying Index Fund Return is negative and expressed as a formula:

Underlying Index Fund Return = ($51.00 - $60.00) / $60.00 = -15.00%

Payment at Maturity = $10.00

Because the Underlying Index Fund Return is less than zero, but the Final Price is greater than or equal to the Downside Threshold on the Final Valuation Date, HSBC will pay you a Payment at Maturity equal to $10.00 per $10.00 Principal Amount of Securities (a return of zero percent).

Example 4— The price of the Underlying Index Fund decreases from an Initial Price of $60.00 to a Final Price of $12.00. The Underlying Index Fund Return is negative and expressed as a formula:

Underlying Index Fund Return = ($12.00 - $60.00) / $60.00 = -80.00%

Payment at Maturity = $10 + ($10 × -80.00%) = $2.00

Because the Underlying Index Fund Return is less than zero and the Final Price is below the Downside Threshold on the Final Valuation Date, the Securities will be fully exposed to any decline in the price of the Underlying Index Fund on the Final Valuation Date. Therefore, the return on the Securities is -80.00%. In this case, you would incur a loss of 80.00% on the Securities.

If the Final Price is below the Downside Threshold on the Final Valuation Date, the Securities will be fully exposed to any decline in the Underlying Index Fund, and you will lose some or all of your Principal Amount at maturity.

What Are the Tax Consequences of the Securities?

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 each of the Securities. 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 Securities. Under one reasonable approach, the Securities should be treated as pre-paid cash settled executory contracts with respect to the Underlying Index Fund. HSBC intends to treat the Securities consistent with this approach and pursuant to the terms of the Securities, you agree to treat the Securities 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, Morrison & Foerster LLP, it is reasonable to treat the Securities in accordance with this approach. Pursuant to this approach, and subject to the discussion below regarding “constructive ownership transactions,” HSBC does not intend to report any income or gain with respect to the Securities prior to their maturity or an earlier sale or exchange and HSBC intends to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Security for more than one year at such time 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 as Executory Contracts" in the accompanying prospectus supplement for certain U.S. federal income tax considerations applicable to Securities that are treated as pre-paid cash-settled executory contracts.

Despite the foregoing, U.S. holders (as defined in the accompanying prospectus supplement) should be aware that the Internal Revenue Code of 1986, as amended (the “Code”) contains a provision, Section 1260 of the Code, which sets forth rules which are applicable to what it refers to as “constructive ownership transactions.” Due to the manner in which it is drafted, the precise applicability of Section 1260 of the Code to any particular transaction is often uncertain. In general, a “constructive ownership transaction” includes a contract under which an investor will receive payment equal to or credit for the future value of any equity interest in a regulated investment company (such as shares of the Underlying Index Fund (the “Underlying Shares”)). Under the “constructive ownership” rules, if an investment in a Security is treated as a “constructive ownership transaction,” any long-term capital gain recognized by a U.S. holder in respect of the Security will be recharacterized as ordinary income to the extent such gain exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Code) (the “Excess Gain”). In addition, an interest charge will also apply to any deemed underpayment of tax in respect of any Excess Gain to the extent such gain would have resulted in gross income inclusion for the U.S. holder in taxable years prior to the taxable year of the sale, exchange or maturity of the Security (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale, exchange or maturity of the Security). Furthermore, unless otherwise established by clear and convincing evidence, the “net underlying long-term capital gain” is treated as zero.

Although the matter is not clear, there exists a risk that an investment in a Security will be treated as a “constructive ownership transaction.” If such treatment applies, it is not entirely clear to what extent any long-term capital gain recognized by a U.S. holder in respect of a Security will be recharacterized as ordinary income. It is possible, for example, that the amount of the Excess Gain (if any) that would be recharacterized as ordinary income in respect of each Security will equal the excess of (i) any long-term capital gain recognized by the U.S. holder in respect of such a Security over (ii) the “net underlying long-term capital gain” such U.S. holder would have had if such U.S. holder had acquired a number of the Underlying Shares at fair market value on the original issue date of such Security for an amount equal to the “issue price” of the Security and, upon the date of sale, exchange or maturity of the Security, sold such Underlying Shares at fair market value (which would reflect the percentage increase in the value of the Underlying Shares over the term of the Security). Accordingly, it is possible that all or a portion of any gain on the sale or settlement of the Security after one year could be treated as “Excess Gain” from a “constructive ownership transaction,” which gain would be recharacterized as ordinary income, and subject to an interest charge. U.S. holders should consult their tax advisors regarding the potential application of the “constructive ownership” rules.

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 Securities, other characterizations and treatments are possible and the timing and character of income in respect of the Securities might differ from the treatment described above. For example, the Securities 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 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 Securities) 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 Security is required to accrue income in respect of the Security prior to the receipt of payments with respect to the Security or its 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 a Security as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder (as defined in the accompanying prospectus supplement) of the Security could be subject to U.S. withholding tax in respect of a Security. It is unclear whether any regulations or other guidance would apply to the Securities (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 Securities.

We will not attempt to ascertain whether the Underlying Index Fund or any of the entities whose stock is owned by the Underlying Index Fund 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 the Underlying Index Fund or one or more of the entities whose stock is owned by the Underlying Index Fund were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to

11

information filed with the SEC and other authorities by the Underlying Index Fund the entities whose stock is owned by the Underlying Index Fund and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is owned by the Underlying Index Fund is or becomes a PFIC or USRPHC.

Under current law, while the matter is not entirely clear, individual non-U.S. holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, the Securities are likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their tax advisors regarding the U.S. federal estate tax consequences of investing in the Securities.

Recently finalized Treasury Regulations provide that withholding on “dividend equivalent” payments (as discussed in the accompanying prospectus supplement), if any, will not apply to Securities issued before January 1, 2017. Additionally, the IRS has announced that withholding under the Foreign Account Tax Compliance Act (as discussed in the accompanying prospectus supplement) on payments of gross proceeds from a sale, exchange, redemption or other disposition of the Securities will only apply to dispositions after December 31, 2018.

PROSPECTIVE PURCHASERS OF SECURITIES 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 SECURITIES.

Events of Default and Acceleration

If the Securities have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the Securities, the Calculation Agent will determine the accelerated payment due and payable at maturity in the same general manner as described in “Indicative Terms” in this free writing prospectus. In that case, the scheduled trading day preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the Underlying Index Fund Return. If a Market Disruption Event exists with respect to the Underlying Index Fund on that scheduled trading day, then the accelerated Final Valuation Date for the Underlying Index Fund 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.

If the Securities have become immediately due and payable following an event of default, you will not be entitled to any additional payments with respect to the Securities. 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 Securities from HSBC for distribution to UBS Financial Services Inc. (the “Agent”). HSBC will agree to sell to the Agent, and the Agent will agree to purchase, all of the Securities at the price indicated on the cover of the pricing supplement, which is the document that will be filed pursuant to Rule 424(b)(2) containing the final pricing terms of the Securities. 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 of this free writing prospectus.

Subject to regulatory constraints, HSBC USA Inc. (or an affiliate thereof) intends to offer to purchase the Securities 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 the Agent, in connection with the sale of the Securities and the Agent 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 the pricing supplement related to this free writing prospectus in market-making transactions after the initial sale of the Securities, but is under no obligation to make a market in the Securities and may discontinue any market-making activities at any time without notice.
