due April 5, 2022

Buffered Performance Upside Securities^SM
Principal at Risk Securities

The Dual Directional Buffered Participation Securities are senior unsecured debt securities of HSBC USA Inc. (“HSBC”), will not pay interest, provide for a maximum return of 13% of the principal amount at maturity and have the terms described in the accompanying Equity Index Underlying Supplement, prospectus supplement and prospectus, as supplemented or modified by this pricing supplement. All references to “Reference Asset” in the prospectus supplement and the Equity Index Underlying Supplement shall refer to the “underlying index” herein. At maturity, if the level of the underlying index has remained the same or appreciated, investors will receive the stated principal amount of their investment plus the upside performance of the underlying index, subject to the maximum payment at maturity. If the level of the underlying index has depreciated by no more than 10%, the investor will receive the stated principal amount plus an unleveraged positive return equal to the absolute value of the percentage decline, which will effectively be limited to a positive return of 10%. However, if the level of the underlying index has depreciated by more than the buffer amount of 10%, investors will lose 1% of the stated principal amount for every 1% decline in the level of the underlying index beyond the buffer amount. These Buffered Participation Securities are for investors who seek an equity index-based return and who are willing to risk their principal and forgo current income and upside above the maximum payment at maturity in exchange for the leverage feature, which applies to a limited range of positive performance of the underlying index, and the unleveraged absolute return feature, which applies to a limited range of negative performance of the underlying index. Investors may lose some or a significant portion (up to 90%) of the stated principal amount of the Buffered Participation Securities. All payments on the Buffered Participation Securities are subject to the credit risk of HSBC.

Investment Summary

Dual Directional Buffered Participation Securities
Principal at Risk Securities

The Dual Directional Buffered Participation Securities Based on the Level of the Nasdaq-100 Index^® due April 5, 2022 (the “Buffered Participation Securities”) can be used:

§ As an alternative to direct exposure to the underlying index that captures 1:1 returns for any positive performance of the underlying index, subject to the maximum payment at maturity

§ To obtain an unleveraged positive return for a limited range of negative performance of the underlying index

§ To potentially outperform the underlying index in a moderately bearish scenario to the extent that the final level is less than the initial level by an amount equal to or less than the buffer amount

§ To obtain a buffer against a specified level of negative performance in the underlying index

Maturity:	Approximately 18 months
Leverage factor:	100%
Maximum payment at maturity:	$11.30 per Buffered Participation Security (113% of the stated principal amount)
Minimum payment at maturity:	$1, subject to the credit risk of HSBC
Buffer amount:	10%.

Key Investment Rationale

The Buffered Participation Securities offer a 1:1 exposure on the positive performance of the underlying index, and an unleveraged positive return on the absolute value of a limited range of negative performance of the underlying index. At maturity, if the level of the underlying index has remained the same or appreciated, investors will receive the stated principal amount of their investment plus a return reflecting the unleveraged upside performance of the underlying index, subject to the maximum payment at maturity. If the level of the underlying index has depreciated by no more than 10%, investors will receive the stated principal amount plus an unleveraged positive return equal to the absolute value of the percentage decline, which will effectively be limited to a positive return of 10%. However, if the level of the underlying index has declined from the initial level by more than the buffer amount as of the valuation date, investors will lose 1% for every 1% decrease in the level of the underlying index by more than the buffer amount. Investors may lose some or a significant portion (up to 90%) of the stated principal amount of the Buffered Participation Securities.

These Trigger Participation Securities are for investors who seek an equity index-based return and who are willing to risk up to 90% of their principal and forgo current income and upside in excess of the maximum payment at maturity in exchange for the unleveraged absolute return feature, which applies to a limited range of negative performance of the underlying index. All payments on the Buffered Participation Securities are subject to the credit risk of HSBC.

1:1 Upside Performance	The Buffered Participation Securities offer investors an opportunity to capture 1:1 returns for any positive performance relative to a direct investment in the securities included in the underlying index, subject to the maximum payment at maturity.
Absolute Return Feature	The Buffered Participation Securities enable investors to obtain an unleveraged positive return if the final level is less than the initial level by an amount equal to or less than the buffer amount.
Buffer Feature	At maturity, even if the level of the underlying index has declined over the term of the Buffered Participation Securities, you will receive your stated principal amount, but only if the level of the underlying index has declined by no more than the buffer amount from the initial level.
Upside Scenario if the Underlying Index Remains the Same or Appreciates	The final level of the underlying index is greater than or equal to the initial level and, at maturity for each Buffered Participation Security, we will pay the stated principal amount of $10 plus 100% of the index percent change, subject to the maximum payment at maturity of $11.30 per Buffered Participation Security (113% of the stated principal amount).
Absolute Return Scenario	The final level is less than the initial level by an amount equal to or less than the buffer amount. In this case, investors receive a 1% positive return on the Buffered Participation Securities for each 1% decline in the level of the underlying index. For example, if the final level is 10% less than the initial level, the Buffered Participation Securities will provide a total positive return of 10% at maturity. The maximum return you may receive in this scenario is a positive 10% return at maturity.

Principal at Risk Securities

Downside Scenario The level of the underlying index depreciates from the initial level by more than 10%, and, at maturity for each Buffered Participation Security, you will lose 1% for every 1% that the level of the underlying index has decreased by more than 10%. For example, if the final level is 70% less than the initial level, the payment on the Trigger Participation Securities will result in a loss of 60% of principal at $4.00, or 40% of the stated principal amount.

How the Buffered Participation Securities Work

Payoff Diagram

The payoff diagram below illustrates the payment at maturity on the Buffered Participation Securities are based on the following terms:

Buffered Participation Securities Payoff Diagram

How it works

§ Upside Scenario: If the final level is greater than the initial level, investors would receive the $10 stated principal amount plus 100% of the appreciation of the underlying index, subject to the maximum payment at maturity.

§ For example, with the leverage factor of 100%, if the underlying index appreciates 10%, investors would receive a 10.00% return, or $11.00 per Buffered Participation Security.

§ For example, if the level of the underlying index appreciates 50%, the investors would receive only the maximum payment at maturity of $11.30 per Buffered Participation Security, or 113% of the stated principal amount.

§ Absolute Return Scenario: If the final level is less than the initial level by an amount equal to or less than the buffer amount, investors would receive a 1% positive return on the Buffered Participation Securities for each 1% decline in the underlying index.

§ For example, if the level of the underlying index declines by 10%, investors would receive a 10% return, or $11.00 per Buffered Participation Security.

§ The maximum return under this scenario is a positive 10% return at maturity, or $11.00 per Buffered Participation Security.

§ Downside Scenario: If the final level is less than the initial level by an amount greater than the buffer amount, investors would receive an amount that is less than the stated principal amount of $10 by an amount that is proportionate to the decrease in the level of the underlying index beyond the buffer amount.

§ For example, if the underlying index declines by 40%, investors would lose 30% of their principal and receive only $7.00 per Buffered Participation Security at maturity, or 70% of the stated principal amount. You may lose some or a significant portion (up to 90%) of your principal.

Risk Factors

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

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 Buffered Participation Securities described in the following sections:

“— Risks relating to all note issuances” in the prospectus supplement; and

“— 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.

§ Buffered Participation Securities do not pay interest. The terms of the Buffered Participation Securities differ from those of ordinary debt securities in that the Buffered Participation Securities do not pay interest, and will provide for the return of only 10% of the principal amount at maturity. If the level of the underlying index depreciates from the initial level by more than 10%, you will receive for each Buffered Participation Security that you hold a payment at maturity that is less than the stated principal amount by an amount proportionate to the decline in the level of the underlying index beyond the buffer amount, subject to the credit risk of HSBC. You may lose up to 90% of the stated principal amount of the Buffered Participation Securities.

§ The appreciation potential of the Buffered Participation Securities is limited by the maximum payment at maturity. The appreciation potential of the Buffered Participation Securities is limited by the maximum payment at maturity of $11.30 per Buffered Participation Security (113% of the stated principal amount). Although the leverage factor provides 100% exposure to any amount by which the final level is greater than the initial level, because the payment at maturity will be limited to 113% of the stated principal amount for the Buffered Participation Securities, any increase in the final level over the initial level by more than 13% of the initial level will not further increase the return on the Buffered Participation Securities.

§ Credit risk of HSBC USA Inc. The Buffered Participation 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 Buffered Participation 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 Buffered Participation Securities 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 Buffered Participation Securities 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 Buffered Participation Securities.

§ The market price will be influenced by many unpredictable factors. Several factors will influence the value of the Buffered Participation Securities in the secondary market and the price at which HSBC Securities (USA) Inc. may be willing to purchase or sell the Buffered Participation Securities in the secondary market, including: the value, volatility and dividend yield, as applicable, of the underlying index and the securities comprising the underlying index, interest and yield rates, time remaining to maturity, geopolitical conditions and economic, financial, political and regulatory or judicial events and any actual or anticipated changes in our credit ratings or credit spreads. Generally, the longer the time remaining to maturity, the more the market price of the Buffered Participation Securities will be affected by the other factors described above. The level of the underlying index may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. See “Information about the Nasdaq-100 Index^®” below. You may receive less, and possibly significantly less, than the stated principal amount per Buffered Participation Security if you try to sell your Buffered Participation Securities prior to maturity.

§ Investing in the Buffered Participation Securities is not equivalent to investing in the underlying index. Investing in the Buffered Participation Securities is not equivalent to investing in the underlying index or its component securities. Investors in the Buffered Participation Securities will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the securities comprising the underlying index.

§ Non-U.S. Securities Risk. Some of the equity securities included in the NDX are issued by non-U.S. companies. Investments in securities linked to the value of such non-U.S. equity securities, such as the Buffered Participation Securities, involve risks associated with the home countries of the issuers of those non-U.S. equity securities. The prices of securities in non-U.S. markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws

§ Adjustments to the underlying index could adversely affect the value of the Buffered Participation Securities. Nasdaq, Inc., the reference sponsor of the underlying index, may add, delete or substitute the stocks comprising the underlying index. In addition, the reference sponsor of the underlying index may make other methodological changes that could change the level of the underlying index. Further, the reference sponsor of the underlying index may discontinue or suspend calculation or publication of the underlying index at any time. Any such actions could affect the value of and the return on the Buffered Participation Securities.

§ The estimated initial value of the Buffered Participation Securities, 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 Buffered Participation Securities in the secondary market, if any. The estimated initial value of the Buffered Participation Securities 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 Buffered Participation Securities. This internal funding rate is typically lower than the rate we would pay 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 Buffered Participation Securities 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 Buffered Participation Securities to be more favorable to you. We determined the value of the embedded derivatives in the Buffered Participation 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 Buffered Participation 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 Buffered Participation Securities in the secondary market (if any exists) at any time.

§ The price of your Buffered Participation Securities in the secondary market, if any, immediately after the pricing date is expected to 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 Buffered Participation Securities, the underwriting discount and the costs associated with structuring and hedging our obligations under the Buffered Participation 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 Buffered Participation Securities in the secondary market, if any, the price you would receive for your Buffered Participation 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 Buffered Participation Securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the underlying index and changes in market conditions, and cannot be predicted with accuracy. The Buffered Participation Securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Buffered Participation Securities to maturity. Any sale of the Buffered Participation Securities prior to maturity could result in a loss to you.

§ If HSBC Securities (USA) Inc. were to repurchase your Buffered Participation Securities immediately after the original issue date, the price you receive may be higher than the estimated initial value of the Buffered Participation Securities. 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 Buffered Participation 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 pricing date for a temporary period expected to be approximately 1 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 Buffered Participation Securities and other costs in connection with the Buffered Participation Securities that we will no longer expect to incur over the term of the Buffered Participation 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 Buffered Participation Securities and any agreement we may have with

September 2020 Page 8

Dual Directional Buffered Participation Securities Based on the Level of the Nasdaq-100 Index^® due April 5, 2022

Buffered Performance Upside Securities^SM

Principal at Risk Securities

the distributors of the Buffered Participation Securities. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the original issue date of the Buffered Participation Securities based on changes in market conditions and other factors that cannot be predicted.

§ The amount payable on the Buffered Participation Securities is not linked to the level of the underlying index at any time other than the valuation date. The final level will be based on the official closing level of the underlying index on the valuation date, subject to postponement for non-trading days and certain market disruption events. Even if the level of the underlying index appreciates prior to the valuation date but then decreases by the valuation date, the payment at maturity may be less, and may be significantly less, than it would have been had the payment at maturity been linked to the level of the underlying index prior to that decrease. Although the actual level of the underlying index on the stated maturity date or at other times during the term of the Buffered Participation Securities may be higher than the final level, the payment at maturity will be based solely on the official closing level of the underlying index on the valuation date.

§ The Buffered Participation Securities will not be listed on any securities exchange and secondary trading may be limited. The Buffered Participation Securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the Buffered Participation Securities. HSBC Securities (USA) Inc. may, but is not obligated to, make a market in the Buffered Participation Securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Buffered Participation Securities easily. Because we do not expect that other broker-dealers will participate significantly in the secondary market for the Buffered Participation Securities, the price at which you may be able to trade your Buffered Participation Securities is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to transact. If, at any time, HSBC Securities (USA) Inc. were to cease making a market in the Buffered Participation Securities, it is likely that there would be no secondary market for the Buffered Participation Securities. Accordingly, you should be willing to hold your Buffered Participation Securities to maturity.

§ The calculation agent, which is HSBC or one of its affiliates, will make determinations with respect to the Buffered Participation Securities. As calculation agent, HSBC or one of its affiliates has determined the initial level and will determine the final level and the amount of cash, if any, that you will receive at maturity. Moreover, certain determinations made by HSBC or one of its affiliates in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or the calculation of the final level in the event of a discontinuance of the underlying index. These determinations, which may be subjective, may adversely affect the payout to you at maturity. Although the calculation agent has made and will make all determinations and take all action in relation to the Buffered Participation Securities in good faith, it should be noted that such discretion could have an impact (positive or negative) on the value of your Buffered Participation Securities. The calculation agent is under no obligation to consider your interests as a holder of the Buffered Participation Securities in taking any actions, including the determination of the initial level, that might affect the value of your Buffered Participation Securities. See “Additional Terms of the Notes—Discontinuance or Modification of an Index” and “—Market Disruption Event” in the Equity Index Underlying Supplement.

§ Hedging and trading activity by our affiliates could potentially adversely affect the value of the Buffered Participation Securities. One or more of our affiliates and/or third-party dealers have carried out and will continue to carry out hedging activities related to the Buffered Participation Securities (and possibly to other instruments linked to the underlying index or its component stocks), including trading in the stocks that constitute the underlying index as well as in other instruments related to the underlying index. As a result, these entities may be unwinding or adjusting hedge positions during the term of the Buffered Participation Securities and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches. Some of our affiliates also trade those stocks and other financial instruments relating to the underlying index on a regular basis as part of their general broker-dealer and other businesses. Any of these hedging or trading activities on or prior to the pricing date could have increased the initial level and, therefore, could have increased the level at which the underlying index must close so that an investor does not suffer a loss on the investor’s initial investment in the Buffered Participation Securities. Additionally, hedging or trading activities during the term of the Buffered Participation Securities, including on the valuation date, could adversely affect the level of the underlying index on the valuation date and, accordingly, the amount of cash, if any, an investor will receive at maturity.

Additional Information About the Buffered Participation Securities

Please read this information in conjunction with the final terms on the cover page of this document.

General Information
Listing:	The Buffered Participation Securities will not be listed on any securities exchange.
CUSIP:	40438Q829
ISIN:	US40438Q8298
Minimum ticketing size:	$1,000 / 100 Buffered Participation Securities
Denominations:	$10 per Buffered Participation Security and integral multiples thereof
Interest:	None
Tax considerations:	There is no direct legal authority as to the proper tax treatment of each Buffered Participation Security, and therefore significant aspects of the tax treatment of each Buffered Participation Security are uncertain as to both the timing and character of any inclusion in income in respect of each Buffered Participation Security. Under one approach, each Buffered Participation Security could be treated as a pre-paid executory contract with respect to the underlying index. We intend to treat each Buffered Participation Security consistent with this approach. Pursuant to the terms of each Buffered Participation Security, you agree to treat each Buffered Participation Security 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, Mayer Brown LLP, it is reasonable to treat each Buffered Participation Security as a pre-paid executory contract with respect to the underlying index. Pursuant to this approach, we do not intend to report any income or gain with respect to each Buffered Participation Security prior to maturity or an earlier sale or exchange, and we intend 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 Buffered Participation Securities for more than one year at such time for U.S. federal income tax purposes. In Notice 2008-2, the Internal Revenue Service (“IRS”) and the Treasury Department requested comments as to whether the purchaser of certain securities (which may include the Buffered Participation 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 security 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 Buffered Participation Security is required to accrue income in respect of the Buffered Participation Securities prior to the receipt of payments under the Buffered Participation Securities or its earlier sale or exchange. 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 Buffered Participation Security as ordinary income (including gain on a sale or exchange). Finally, it is possible that a non-U.S. holder (as defined under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement) of the Buffered Participation Securities could be subject to U.S. withholding tax in respect of a Buffered Participation Security. It is unclear whether any regulations or other guidance would apply to the Buffered Participation 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 Buffered Participation Securities. We will not attempt to ascertain whether any of the entities whose stock is included in the underlying index would be treated as a passive foreign investment company (a “PFIC”) or United States real property holding corporation (a “USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the underlying index were so treated, certain adverse U.S. federal income tax consequences might apply to a U.S. holder in the case of a PFIC and to a non-U.S. holder in the case of a USRPHC. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in the underlying index and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the underlying index is or becomes a PFIC or a USRPHC. A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2023. Based on the Issuer’s determination that the Buffered Participation Securities are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under a Buffered Participation Security. However, it is possible that the Buffered Participation Securities could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the underlying index or the Buffered Participation Securities, and following such occurrence the Buffered Participation Securities could be treated as subject to withholding on dividend equivalent payments.

	Non-U.S. holders that enter, or have entered, into other transactions in respect of the underlying index or the Buffered Participation Securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Buffered Participation Securities 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. 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 Buffered Participation 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 Buffered Participation Securities. For a further discussion of U.S. federal income tax consequences related to each Buffered Participation Security, see the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.
Calculation agent:	HSBC USA Inc., or one of its affiliates.
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 Buffered Participation Securities from HSBC for distribution to Morgan Stanley Wealth Management. HSBC Securities (USA) Inc. will act as agent for the Buffered Participation Securities and will receive a fee of $0.25 per $10 stated principal amount and will pay Morgan Stanley Wealth Management a fixed sales commission of $0.20 for each Buffered Participation Security they sell. Of the amount per $10 stated principal amount received by HSBC Securities (USA) Inc., acting as agent for HSBC, HSBC Securities (USA) Inc. will pay Morgan Stanley Wealth Management a structuring fee of $0.05 for each Buffered Participation Security. 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 Buffered Participation Securities, but is under no obligation to make a market in the Buffered Participation Securities and may discontinue any market-making activities at any time without notice. Delivery of the Buffered Participation Securities will be made against payment for the Buffered Participation Securities on the original issue date set forth on the cover page of this document, which is more than two business days following the pricing 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 Buffered Participation Securities 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-61 in the prospectus supplement.
Events of default and acceleration:	If the Buffered Participation Securities have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the Buffered Participation Securities, the calculation agent will determine the accelerated payment at maturity due and payable in the same general manner as described in “payment at maturity” in this pricing supplement. In such a case, the third scheduled trading day for the underlying index immediately preceding the date of acceleration will be used as the valuation date for purposes of determining the accelerated final level. If a market disruption event exists on that scheduled trading day, then the accelerated valuation date will be postponed for up to five scheduled trading days (in the same general manner used for postponing the originally scheduled valuation date). The accelerated maturity date will be the fifth business day following such accelerated postponed valuation date. For more information, see “Description of Debt Securities — Senior Debt Securities — Events of Default” in the accompanying prospectus.
Where you can find more information:	This pricing supplement relates to an offering of the Buffered Participation Securities linked to the underlying index. The purchaser of a Buffered Participation Security will acquire a senior unsecured debt security of HSBC USA Inc. Although the offering of Buffered Participation Securities relates to the underlying index, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the underlying index or any security comprising the underlying index or as to the suitability of an investment in the Buffered Participation Securities. HSBC has filed a registration statement (including a prospectus, a 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.
