GENERAL

This pricing supplement relates to the offering of Notes identified on the cover page. The purchaser of a Note will acquire a senior unsecured debt security of HSBC USA Inc. Although the offering of Notes relates to the Underlyings, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to either Underlying or any component security included in any Underlying or as to the suitability of an investment in the Notes.

You should read this document together with the prospectus dated March 5, 2015, the prospectus supplement dated March 5, 2015 and the Equity Index Underlying Supplement dated March 5, 2015. If the terms of the Notes offered hereby are inconsistent with those described in the accompanying prospectus supplement, prospectus or Equity Index Underlying Supplement, the terms described in this pricing supplement shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-7 of this pricing supplement, beginning on page S-1 of the prospectus supplement and beginning on page S-2 of the Equity Index Underlying Supplement, as the Notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, prospectus supplement and Equity Index Underlying Supplement) with the SEC for the offering to which this pricing supplement relates. Before you invest, you should read the prospectus, prospectus supplement and Equity Index Underlying Supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering. You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov. Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and Equity Index Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

PS-4

PAYMENT ON THE NOTES

Call Feature

The Notes will be automatically called if the Official Closing Value of each and every Underlying is at or above its Initial Value on any Call Observation Date. If the Notes are automatically called, investors will receive a cash payment, per $1,000 Principal Amount of Notes, equal to the Principal Amount, plus the applicable Contingent Coupon.

Contingent Coupon

We will pay a quarterly Contingent Coupon payment on a Coupon Payment Date if the Official Closing Level of each Underlying on the applicable Coupon Observation Date is equal to or greater than its Coupon Trigger. Otherwise, no coupon will be paid on such Coupon Payment Date. For information regarding the record dates applicable to the Contingent Coupons payable on the Notes, please see the section entitled “Recipients of Interest Payments” beginning on page S-12 in the accompanying prospectus supplement. The Contingent Coupon Rate is 5.00% per annum ($12.50 per $1,000 in Principal Amount per quarter, if payable, payable in equal installments).

Maturity

Unless the Notes are automatically called, on the Maturity Date and for each $1,000 Principal Amount of Notes, you will receive a cash payment equal to the final coupon payment (if applicable) plus the Final Settlement Value determined as follows:

4 If a Trigger Event does not occur, 100% of the Principal Amount.

4 If a Trigger Event occurs and the Final Return of the Least Performing Underlying is positive or zero, 100% of the Principal Amount.

4 If a Trigger Event occurs and the Final Return of the Least Performing Underlying is negative, 100% of the Principal Amount multiplied by the sum of one plus the Final Return of the Least Performing Underlying, which will result in a Final Settlement Value less than the Principal Amount.

Observation Period

The period from but excluding the Trade Date to and including the Final Valuation Date, subject to adjustment as described under “Additional Terms of the Notes―Observation Periods” in the accompanying Equity Index Underlying Supplement.

Calculation Agent

We or one of our affiliates will act as calculation agent with respect to the Notes.

Reference Sponsors

With respect to the SPX, S&P Dow Jones Indices LLC, a division of S&P Global, is the reference sponsor. With respect to the RTY, FTSE Russell is the reference sponsor.

PS-5

INVESTOR SUITABILITY

The Notes may be suitable for you if:

4 You believe that the Official Closing Level of each of the Underlyings will not be below its Barrier Level on any trading day during the Observation Period.

4 You are willing to accept that the quarterly Contingent Coupon is payable only if the Official Closing Level of each Underlying is greater than or equal to its Coupon Trigger on the applicable Coupon Observation Date.

4 You do not seek an investment that provides an opportunity to participate in the appreciation of either Underlying.

4 You are willing to make an investment that is exposed to the potential downside performance of the Least Performing Underlying on a 1-to-1 basis if the Final Return of the Least Performing Underlying is less than -25%.

4 You are willing to hold Notes that will be automatically called on any Call Observation Date on which the Official Closing Level of each Underlying is at or above its Initial Level, or you are otherwise willing to hold the Notes to maturity.

4 You do not seek an investment for which there will be an active secondary market.

4 You are willing to forgo dividends or other distributions paid to holders of the stocks included in the Underlyings.

4 You are willing to accept the risk and return profile of the Notes versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating.

4 You are comfortable with the creditworthiness of HSBC, as Issuer of the Notes.

The Notes may not be suitable for you if:

4 You believe that the Official Closing Level of one or both of the Underlyings will be below its Barrier Level on any trading day during the Observation Period.

4 You believe the Contingent Coupons will not provide you with your desired return.

4 You seek an investment that provides an opportunity to participate in the appreciation of either Underlying.

4 You are unwilling to make an investment that is exposed to the potential downside performance of the Least Performing Underlying on a 1-to-1 basis if the Final Return of the Least Performing Underlying is less than -25%.

4 You are unable or unwilling to hold Notes that will be automatically called on any Call Observation Date on which the Official Closing Level of each Underlying is at or above its Initial Level, or you are otherwise unable or unwilling to hold the Notes to maturity.

4 You prefer to receive guaranteed periodic interest payments on the Notes.

4 You seek an investment for which there will be an active secondary market.

4 You are not willing to forgo dividends or other distributions paid to holders of the stocks included in the Underlyings.

4 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.

4 You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Notes.

PS-6

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 in the accompanying prospectus supplement and beginning on page S-2 of the accompanying Equity Index Underlying Supplement. Investing in the Notes is not equivalent to investing directly in any of the stocks included in either Underlying. You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying prospectus, prospectus supplement and Equity Index Underlying Supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and Equity Index Underlying Supplement including the explanation of risks relating to the Notes described in the following sections:

4 “—Risks Relating to All Note Issuances” in the prospectus supplement; and

4 “—General Risks Related to Indices” in the Equity Index Underlying Supplement.

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

The Notes do not guarantee return of principal and you may lose all of your Principal Amount.

The Notes do not guarantee any return of principal. The Notes differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount of your Notes if the Notes are not automatically called and the Final Level of the Least Performing Underlying is less than its Barrier Level. In this case, the Payment at Maturity you will be entitled to receive will be less than the Principal Amount of the Notes and you will lose 1% for each 1% that the Final Return of the Least Performing Underlying is less than its Initial Level. You may lose up to 100% of your investment at maturity.

You may not receive any Contingent Coupons.

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

Your return on the Notes is limited to the principal amount plus the Contingent Coupon, if any, regardless of any appreciation in the level of either Underlying.

If the Notes are called, for each $1,000 in principal amount, you will receive $1,000 at maturity plus the Contingent Coupon, regardless of any appreciation in the level of either Underlying, which may be significant. Accordingly, an investment in the Notes may have a lower return than an investment in the stocks represented by an Underlying during the term of the Notes.

The Notes are subject to the credit risk of HSBC USA Inc.

The Notes 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 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 Coupons and any return of principal at maturity or upon early redemption, as applicable, 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 the amounts owed to you under the terms of the Notes.

Changes that affect the Underlyings may affect the market value of the Notes and the amount you will receive at maturity.

The policies of the reference sponsor of each Underlying concerning additions, deletions and substitutions of the constituents included in that Underlying and the manner in which the reference sponsor takes account of certain changes affecting those constituents may affect the level of that Underlying. The policies of the reference sponsor with respect to the calculation of the relevant Underlying could also affect the level of that Underlying. The reference sponsor may discontinue or suspend calculation or dissemination of the relevant Underlying. Any such actions could affect the value of the Notes and their return.

If the Notes are not called and a Trigger Event occurs with respect to any Underlying, your return will be based on the Final Return of the Least Performing Underlying.

The performance of either of the Underlyings may cause a Trigger Event to occur. If a Trigger Event occurs and the Notes are not automatically called, your return will be based on the Final Return of the Least Performing Underlying without regard to the performance of the other Underlying or which Underlying caused the Trigger Event to occur. As a result, you could lose all or some of your initial investment if the Final Return of the Least Performing Underlying is negative and a Trigger Event occurs, even if there is an increase in the level of the other Underlying. This could be the case even if the other Underlying caused the Trigger Event to occur or the other Underlying increased by an amount greater than the decrease in the Least Performing Underlying.

PS-7

Since the Notes are linked to the performance of more than one Underlying, you will be fully exposed to the risk of fluctuations in the level of each Underlying.

Since the Notes are linked to the performance of more than one Underlying, the Notes will be linked to the individual performance of each Underlying. Because the Notes are not linked to a weighted basket, in which 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 level of each Underlying. For example, in the case of notes linked to a weighted basket, the return would depend on the weighted aggregate performance of the basket components reflected as the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component, as scaled by the weightings of such basket components. However, in the case of these Notes, the individual performance of each of the Underlyings would not be combined to calculate your return and the depreciation of either Underlying would not be mitigated by the appreciation of the other Underlying. Instead, your return would depend on the Least Performing Underlying.

The Notes may be automatically called prior to the Maturity Date.

If the Notes are automatically called early, the holding period could be as little as 6 months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are automatically called prior to the Maturity Date.

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 the payments due on the Notes.

The Estimated Initial Value of the Notes, which was determined by us on the Pricing 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 Pricing 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 Pricing Date may be less than the price to public.

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, 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. 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 levels 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 we were to repurchase your Notes immediately after the Original Issue 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 Original Issue 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 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 Pricing Date for a temporary period expected to be approximately 12 months after the Original Issue 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

PS-8

reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

The Notes lack liquidity.

The Notes will not be listed on any securities exchange. HSBC Securities (USA) Inc. is not required to offer to purchase the Notes in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. 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 HSBC Securities (USA) Inc. is willing to buy the Notes.

Potential conflicts of interest may exist.

HSBC and its affiliates play a variety of roles in connection with the issuance of the Notes, including acting as calculation agent and hedging our obligations under the Notes. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the Notes. We will not have any obligation to consider your interests as a holder of the Notes in taking any action that might affect the value of your Notes.

The Notes are subject to small-capitalization risk. 

The RTY tracks companies that are 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 level of the RTY may be more volatile than an investment in stocks issued by large-capitalization companies. Stock prices of small-capitalization companies may also be 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 RTY to track them. In addition, small-capitalization companies are often 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. These companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

Uncertain tax treatment.

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

ILLUSTRATIVE EXAMPLES

The following table and examples 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 level of either Underlying relative to its Initial Level. We cannot predict the Official Closing Level of either Underlying on any Coupon Observation Date or the Final Valuation Date. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Underlyings or return on the Notes.

The table and examples below illustrate how the Final Settlement Value on a $1,000 investment in the Notes for a hypothetical range of Final Returns of the Least Performing Underlying from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Notes” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount to $1,000. The potential returns described here assume that the Notes have not been automatically called prior to maturity and that the Contingent Coupon is payable on every Coupon Payment Date. You should consider carefully whether the Notes are suitable to your investment goals. If the Official Closing Level of each Underlying on every Coupon Observation Date is greater than or equal to its Coupon Trigger and the Notes are not automatically called, the Contingent Coupons payable over the term of the Notes would total $75.00 per $1,000 Principal Amount (based on the Contingent Coupon Rate of 5.00% per annum). The numbers appearing in the following table and examples have been rounded for ease of analysis. The following table and examples are based on the following terms:

4	Principal Amount:	$1,000
4	Hypothetical Coupon Trigger:	1,500 with respect to the SPX and 825 with respect to the RTY (each of which is 75% of its Hypothetical Initial Level)
4	Hypothetical Barrier Level:	1,500 with respect to the SPX and 825 with respect to the RTY (each of which is 75% of its Hypothetical Initial Level)
4	Contingent Coupon Rate:	5.00% per annum (1.25% for each quarter)

¹ The Official Closing Level of each Underlying never falls below its respective Barrier Level on any trading day during the Observation Period.

² The Official Closing Level of either Underlying falls below its Barrier Level on any trading day during the Observation Period.

³ Assuming the Notes have been held to maturity, and the Underlying has not fallen below 75% of the Initial Level on a Coupon Observation date, the total amount of the coupons paid on the Notes as of the Maturity Date will equal $75.00, with coupon payments of $12.50 made on each Coupon Payment Date.

The examples provided herein are for illustration purposes only. The actual Final Settlement Value, if any, will depend on whether the Notes are automatically called and if a Trigger Event occurs and, if so, the Final Return of the Least Performing Underlying. You should not take these examples as an indication of potential payments. It is not possible to predict whether the Notes will be automatically called and if a Trigger Event will occur and, if so, whether and to what extent the Final Return of the Least Performing Underlying will be less than zero.

Example 1: The Notes are not automatically called and the Official Closing Level of at least one Underlying falls below its Barrier Level during the Observation Period, therefore a Trigger Event occurs. Additionally, the Final Return of the Least Performing Underlying is less than zero.

Underlying	Initial Level	Lowest Official Closing Level During the Observation Period	Final Level
SPX	2,000.00	1,300.00 (65% of Initial Level)	1,300.00 (65% of Initial Level)
RTY	1,100.00	605.00 (55% of Initial Level)	660.00 (60% of Initial Level)

Since each of the Official Closing Levels of SPX and RTY are below their respective Barrier Levels during the Observation Period, a Trigger Event occurs. RTY is the Least Performing Underlying.

Therefore, the Final Return of the Least Performing Underlying =

    Final Level of RTY – Initial Level of RTY    
Initial Level of RTY

= (660.00 – 1,100.00) / 1,100.00= -40.00%

Final Settlement Value = Principal Amount of the Notes × (1 + Final Return of the Least Performing Underlying)

= $1,000 × (1 + -40%) = 600.00

Therefore, the total payment on the Notes is $600.00 in addition to any contingent coupons paid out over the term of the Notes.

Example 2: The Notes are not automatically called and a Trigger Event occurs, even though the Least Performing Underlying is not below its Barrier Level on the Final Valuation Date. Additionally, the Final Return of the Least Performing Underlying is less than zero.

Underlying	Initial Level	Lowest Official Closing Level During the Observation Period	Final Level
SPX	2,000.00	1,700.00 (85% of Initial Level)	1,760.00 (88% of Initial Level)
RTY	1,100.00	605.00 (55% of Initial Level)	1,045.00 (95% of Initial Level)

Since the Official Closing Level of RTY is below its Barrier Level during the Observation Period, a Trigger Event occurs. SPX is the Least Performing Underlying, even though its Official Closing Level never falls below its Barrier Level.

Therefore, the Final Return of the Least Performing Underlying =

    Final Level of SPX – Initial Level of SPX    
Initial Level of SPX

= (1,760.00 – 2,000.00) / 2,000.00= -12.00%

Final Settlement Value = Principal Amount of the Notes × (1 + Final Return of the Least Performing Underlying)

= $1,000 × (1 + -12%) = $880.00

Therefore, the total payment on the Notes is $880.00 in addition to any contingent coupons paid out over the term of the Notes.

PS-11

Example 3: The Notes are not automatically called and a Trigger Event does not occur.

Underlying	Initial Level	Lowest Official Closing Level During the Observation Period	Final Level
SPX	2,000.00	1,700.00 (85% of Initial Level)	1,800.00 (90% of Initial Level)
RTY	1,100.00	990.00 (90% of Initial Level)	990.00 (90% of Initial Level)

Since the Official Closing Level of each Underlying was not below its Barrier Level during the Observation Period, a Trigger Event does not occur.

Therefore, the Final Settlement Value equals $1,000.

Therefore, the total payment on the Notes is $1,000.00 in addition to any contingent coupons paid out over the term of the Notes.

Example 4: The Notes are automatically called on the first Call Observation Date.

Underlying	Initial Level	Official Closing Level on the first Call Observation Date
SPX	2,000.00	2,100.00
RTY	1,100.00	1,210.00

Since the Official Closing Level of both Underlyings was at or above their respective Initial Levels, the Notes were automatically called and you are no longer entitled to receive any Final Settlement Value. Therefore, on the corresponding Call Payment Date you would receive your $1,000 Principal Amount of Notes plus the coupon payment of $12.50 owed to you on that date. As a result, on the first Call Payment Date, you would be entitled to receive a total payment of $1,012.50. Once the Notes are automatically called, they will no longer remain outstanding and there will not be any further coupon payments on the Notes.

INFORMATION RELATING TO THE UNDERLYINGS

Description of the SPX   The SPX is a capitalization-weighted index of 500 U.S. stocks. It is designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries.   As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the SPX. Constituents of the SPX prior to July 31, 2017 with multiple share class lines have been grandfathered in and will continue to be included in the SPX. If a constituent company of the SPX reorganizes into a multiple share class line structure, that company will remain in the SPX at the discretion of the S&P Index Committee in order to minimize turnover.   The top 5 industry groups by market capitalization as of December 29, 2017 were: Information Technology, Financials, Health Care, Consumer Discretionary and Industrials.   For more information about the SPX, see “The S&P 500^Ò Index” beginning on page S-44 of the accompanying Equity Index Underlying Supplement. Historical Performance of the SPX   The following graph sets forth the historical performance of the SPX based on the daily historical closing levels from January 2, 2008 through January 26, 2018. We obtained the closing levels below from the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service.  

The historical levels of the SPX should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the SPX on any Coupon Observation Date or the Final Valuation Date.

Description of the RTY   The RTY is designed to track the performance of the small capitalization segment of the United States equity market. All 2,000 stocks are traded on the New York Stock Exchange or NASDAQ, and the RTY consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 3000^® Index is composed of the 3,000 largest United States companies as determined by market capitalization and represents approximately 98% of the United States equity market.   RTY constituents are required to have greater than 5% of the company’s voting rights (aggregated across all of its equity securities, including, where identifiable, those that are not listed or trading) in the hands of unrestricted shareholders in order to be eligible for index inclusion. Current constituents who do not meet this requirement will have until the September 2022 review to meet the requirement or they will be removed from the RTY.   The top 5 industry groups by market capitalization as of December 31, 2017 were: Financial Services, Health Care, Producer Durables, Consumer Discretionary, and Technology.   For more information about the RTY, see “The Russell 2000^Ò Index” beginning on page S-36 of the accompanying Equity Index Underlying Supplement. Historical Performance of the RTY   The following graph sets forth the historical performance of the RTY based on the daily historical closing levels from January 1, 2008 through January 26, 2018. We obtained the closing levels below from the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service.  

The historical levels of the RTY should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the RTY on any Coupon Observation Date or the Final Valuation Date.

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 in the same general manner as described in this pricing supplement except that in such a case, the scheduled trading day immediately preceding the date of acceleration will be used as the final Coupon Observation Date and the Final Valuation Date. If a market disruption event exists with respect to an Underlying on that scheduled trading day, then the accelerated Final Valuation Date 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 following the postponed accelerated Final Valuation Date. 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 Final Level will be made on such date, irrespective of the existence of a market disruption event with respect to the 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)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the Notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the Notes from HSBC at the price to public less the underwriting discount set forth on the cover page of this pricing supplement for distribution to other registered broker-dealers or will offer the Notes directly to investors. HSBC Securities (USA) Inc. will offer the Notes at the price to public set forth on the cover page of this pricing supplement. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 1.875% and referral fees of up to 0.90% per $1,000 Principal Amount of Notes in connection with the distribution of the Notes to other registered broker-dealers. In no case will the sum of the underwriting discounts and referral fees exceed 2.40% per $1,000 Principal Amount.

An affiliate of HSBC has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the Notes.

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.

Delivery of the Notes will be made against payment for the Notes on the Original Issue Date set forth on the inside cover page of this document, which is more than two business days following the Trade Date. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than two business days prior to the Original Issue Date will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-59 in the prospectus supplement.

No Prospectus (as defined in Directive 2003/71/EC, as amended (the “Prospectus Directive”)) will be prepared in connection with these Notes. Accordingly, these Notes may not be offered to the public in any member state of the European Economic Area (the “EEA”), and any purchaser of these Notes who subsequently sells any of these Notes in any EEA member state must do so only in accordance with the requirements of the Prospectus Directive, as implemented in that member state.

The Notes are not intended to be offered, sold or otherwise made available to, and should not be offered, sold or otherwise made available to, any retail investor in the EEA. For these purposes, the expression “offer" includes the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe the Notes, and a “retail investor” means a person who is one (or more) of: (a) a retail client, as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended (“MiFID II”); or (b) a customer, within the meaning of Insurance Distribution Directive 2016/97/EU, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (c) not a qualified investor as defined in the Prospectus Directive. Consequently, no key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”), for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared, and therefore, offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

PS-14

U.S. FEDERAL INCOME TAX CONSIDERATIONS

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 approach, a Note should be treated as a contingent income-bearing pre-paid executory contract with respect to the Underlyings. We intend to treat the Notes consistent with this approach. 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 the limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Morrison & Foerster LLP, it is reasonable to treat a Note as a contingent income-bearing pre-paid executory contract with respect to the Underlyings. 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 from the treatment described herein. 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.

We will not attempt to ascertain whether 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 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 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 a USRPHC.

U.S. Holders. Please see the discussion under the heading “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 further discussion of U.S. federal income tax considerations applicable to U.S. holders (as defined in the accompanying prospectus supplement). Pursuant to the approach discussed above, we intend 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, we intend to treat any Contingent Coupon, including on the Maturity Date, 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.

Non-U.S. Holders. Please see the discussion under the heading “U.S. Federal Income Tax Considerations—Tax Treatment of Non-U.S. Holders” in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to non-U.S. holders (as defined in the accompanying prospectus supplement). Because the U.S. federal income tax treatment (including the applicability of withholding) 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). We will not pay any additional amounts in respect of such withholding.

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, 2019. Based on the Issuer’s determination that the Notes are not “delta-one” 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 an Underlying 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 an Underlying 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.

PS-15

Foreign Account Tax Compliance Act. The Internal Revenue Service 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 Notes will only apply to dispositions after December 31, 2018.

For a discussion of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

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

VALIDITY OF THE NOTES

In the opinion of Morrison & Foerster 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 March 5, 2015, 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 5, 2015, which has been filed as Exhibit 5.3 to the Issuer’s registration statement on Form

S-3 dated March 5, 2015.
