Trigger Participation Performance Upside Securities^SMPrincipal at Risk Securities

The Dual Directional Trigger Participation Securities are senior unsecured debt securities of HSBC USA Inc. (“HSBC”), will not pay interest, do not guarantee any return of principal 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 10%, investors will be negatively exposed to the full amount of the percentage decline in the underlying index and will lose 1% of the stated principal amount for every 1% decline in the underlying index from the pricing date to the valuation date. These Trigger 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 upside payment, 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.

Investment Summary

Dual Directional Trigger Participation Securities
Principal at Risk Securities

The Dual Directional Trigger Participation Securities Based on the Level of the S&P 500^® Index due August 3, 2022 (the “Trigger 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 but is greater than or equal to the trigger level

Maturity:	Approximately 18 months
Leverage factor:	100%
Maximum payment at maturity:	$11.57 per Trigger Participation Security (115.70% of the stated principal amount)
Minimum payment at maturity:	None. You may lose your entire initial investment in the Trigger Participation Securities.
Trigger level:	90% of the initial level
Coupon:	None

Key Investment Rationale

The Trigger 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 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 decreased by more than 10%, investors will lose 1% of the principal amount for every 1% that the level has declined in the final level from the initial level. Investors may lose up to 100% of the stated principal amount of the Trigger Participation Securities.

These Trigger 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 in excess of the maximum payment at maturity in exchange for the upside payment, 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. All payments on the Trigger Participation Securities are subject to the credit risk of HSBC.

Upside Performance	The Trigger 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 Trigger Participation Securities enable investors to obtain an unleveraged positive return if the final level is less than the initial level but is greater than or equal to the trigger 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 Trigger 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 $11.57 per Trigger Participation Security (115.70% of the stated principal amount).
Absolute Return Scenario	The final level is less than the initial level but is greater than or equal to the trigger level, which is 90% of the initial level. In this case, investors receive a 1% positive return on the Trigger 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 Trigger 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.

Downside Scenario

The final level is less than the trigger level, at maturity for each Trigger Participation Security, we will pay less than the stated principal amount in an amount that is proportionate to the decline in the final level of the underlying index from the initial level. This amount will be less than $9.00 per Trigger Participation Security. 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 70% of principal at $3.00, or 30% of the stated principal amount. There is no minimum payment at maturity on the Trigger Participation Securities.

How the Trigger Participation Securities Work

Payoff Diagram

The payoff diagram below illustrates the payment at maturity on the Trigger Participation Securities assuming the following terms:

Stated principal amount:	$10 per Trigger Participation Security
Leverage factor:	100%
Maximum payment at maturity:	$11.57 per Trigger Participation Security (115.70% of the stated principal amount).
Trigger level:	90% of the initial level

Trigger 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 of $11.57 per Trigger Participation Security. Under the terms of the Trigger Participation Securities, an investor would realize the maximum payment at maturity at a final index level of 115.70% of the initial level.

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 Trigger Participation Security.

For example, if the level of the underlying index appreciates 50%, the investors would receive only the maximum payment at maturity of $11.57 per Trigger Participation Security, or 115.70% of the stated principal amount.

Absolute Return Scenario: If the final level is less than the initial level but is greater than or equal to the trigger level, investors would receive a 1% positive return on the Trigger Participation Securities for each 1% decline in the underlying index.

For example, if the level of the underlying index declines by 5%, investors would receive a 5% return, or $10.50 per Trigger Participation Security.

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

Downside Scenario: If the final level is less than the trigger level, investors would receive an amount that is less than the stated principal amount, based on a 1% loss of principal for each 1% decline in the level of the underlying index. This amount will be less than $9.00 per Trigger Participation Security. There is no minimum payment at maturity on the Trigger Participation Securities.

For example, if the underlying index declines by 40%, investors would lose 40% of their principal and receive only $6.00 per Trigger Participation Security at maturity, or 60% of the stated principal amount.

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 Trigger 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 Trigger Participation Securities and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Trigger 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 Trigger 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.

Risks Relating to the Structure or Features of the Trigger Participation Securities

Trigger Participation Securities do not pay interest and may result in a loss of principal. The terms of the Trigger Participation Securities differ from those of ordinary debt securities in that the Trigger Participation Securities do not pay interest or guarantee payment of the principal amount at maturity. If the final level is less than the trigger level (which is 90% of the initial level), the absolute return feature will no longer be available and you will receive for each Trigger Participation Security that you hold a payment at maturity that is at least 10% less than the stated principal amount of each Trigger Participation Security. In this case, you will lose a portion of your principal amount equal to the percentage decline in the level of the underlying index from the initial level to the final level, subject to the credit risk of HSBC. There is no minimum payment on the Trigger Participation Securities and you may lose up to 100% of the stated principal amount.

The appreciation potential of the Trigger Participation Securities is limited by the maximum payment at maturity. The appreciation potential of the Trigger Participation Securities is limited by the maximum payment at maturity of $11.57 per Trigger Participation Security (115.70% 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 115.70% of the stated principal amount for the Trigger Participation Securities (based on the maximum payment at maturity of $11.57), any increase in the final level over the initial level by more than 15.70% of the initial level will not further increase the return on the Trigger Participation Securities.

The amount payable on the Trigger 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 Trigger 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.

Risks Relating to the Underlying Index

Investing in the Trigger Participation Securities is not equivalent to investing in the underlying index. Investing in the Trigger Participation Securities is not equivalent to investing in the underlying index or its component securities. Investors in the Trigger 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.

Adjustments to the underlying index could adversely affect the value of the Trigger Participation Securities. S&P Dow Jones Indices LLC, 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 Trigger Participation Securities.

General Risk Factors

Credit risk of HSBC USA Inc. The Trigger 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 Trigger 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 Trigger 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 Trigger 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 Trigger Participation Securities.

The estimated initial value of the Trigger 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 Trigger Participation Securities in the secondary market, if any. The estimated initial value of the Trigger 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 Trigger 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 Trigger 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 Trigger Participation Securities to be more favorable to you. We determined the value of the embedded derivatives in the Trigger 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 Trigger 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 Trigger Participation Securities in the secondary market (if any exists) at any time.

The price of your Trigger 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 our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Trigger Participation Securities, the underwriting discount and the costs associated with structuring and hedging our obligations under the Trigger 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 Trigger Participation Securities in the secondary market, if any, the price you would receive for your Trigger 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 Trigger 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 Trigger Participation Securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Trigger Participation Securities to maturity. Any sale of the Trigger Participation Securities prior to maturity could result in a loss to you.

If HSBC Securities (USA) Inc. were to repurchase your Trigger Participation Securities immediately after the original issue date, the price you receive may be higher than the estimated initial value of the Trigger 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 Trigger 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 9 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 Trigger Participation Securities and other costs in connection with the Trigger Participation Securities that we will no longer expect to incur over the term of the Trigger 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 Trigger Participation Securities and any agreement we may have with the distributors of the Trigger 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 Trigger Participation Securities based on changes in market conditions and other factors that cannot be predicted.

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

The calculation agent, which is HSBC or one of its affiliates, will make determinations with respect to the Trigger Participation Securities. As calculation agent, HSBC or one of its affiliates has determined the initial level, the trigger level and will determine the final level, including whether the value of the underlying index has decreased to or below the trigger level, and will calculate the amount of cash, if any, that you will receive at maturity. 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, if any. Although the calculation agent will make all determinations and take all action in relation to the Trigger Participation Securities in good faith, it should be noted that such discretion could have an impact (positive or negative) on the value of your Trigger Participation Securities. The calculation agent is under no obligation to consider your interests as a holder of the Trigger Participation Securities in taking any actions, including the determination of the initial level, that might affect the value of your Trigger Participation Securities.

Hedging and trading activity by our affiliates could potentially adversely affect the value of the Trigger Participation Securities. One or more of our affiliates and/or third-party dealers have carried out and expect to continue to carry out hedging activities related to the Trigger 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 Trigger 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 Trigger Participation Securities. Additionally, hedging or trading activities during the term of the Trigger 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.

The market price will be influenced by many unpredictable factors. Several factors will influence the value of the Trigger Participation Securities in the secondary market and the price at which HSBC Securities (USA) Inc. may be willing to purchase or sell the Trigger 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 Trigger 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 S&P 500^® Index” below. You may receive less, and possibly significantly less, than the stated principal amount per Trigger Participation Security if you try to sell your Trigger Participation Securities prior to maturity.

Additional Information About the Trigger Participation Securities

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

General Information
Listing:	The Trigger Participation Securities will not be listed on any securities exchange.
CUSIP:	40438Q175
ISIN:	US40438Q1756
Minimum ticketing size:	$1,000 / 100 Trigger Participation Securities
Denominations:	$10 per Trigger Participation Security and integral multiples thereof
Interest:	None
Tax considerations:	There is no direct legal authority as to the proper tax treatment of each Trigger Participation Security, and therefore significant aspects of the tax treatment of each Trigger Participation Security are uncertain as to both the timing and character of any inclusion in income in respect of each Trigger Participation Security. Under one approach, each Trigger Participation Security could be treated as a pre-paid executory contract with respect to the underlying index. We intend to treat each Trigger Participation Security consistent with this approach. Pursuant to the terms of each Trigger Participation Security, you agree to treat each Trigger 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 Trigger 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 Trigger 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 Trigger 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 Trigger 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 Trigger Participation Security is required to accrue income in respect of the Trigger Participation Security prior to the receipt of payments under the Trigger Participation Security 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 Trigger 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 Trigger Participation Securities could be subject to U.S. withholding tax in respect of a Trigger Participation Security. It is unclear whether any regulations or other guidance would apply to the Trigger 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 Trigger 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 Trigger 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 Trigger Participation Security. However, it is possible that the Trigger 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 Trigger Participation Securities, and following such occurrence the Trigger 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 Trigger Participation Securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Trigger 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 Trigger 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 Trigger Participation Securities. For a further discussion of U.S. federal income tax consequences related to each Trigger 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 Trigger Participation Securities from HSBC for distribution to Morgan Stanley Wealth Management. HSBC Securities (USA) Inc. will act as agent for the Trigger 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 Trigger 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 Trigger Participation Security. In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use this pricing in market-making transactions after the initial sale of the Trigger Participation Securities, but is under no obligation to make a market in the Trigger Participation Securities and may discontinue any market-making activities at any time without notice. Delivery of the Trigger Participation Securities will be made against payment for the Trigger 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 Trigger 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. References in the accompanying prospectus and prospectus supplement to any European law, regulation or directive (or, in each case, any part thereof) shall, in respect of the United Kingdom, be to such European law, regulation or, as the case may be, directive (or part thereof) as it forms part of United Kingdom domestic law at the time of the relevant offer, sale or making available of the Trigger Participation Securities (and as amended, supplemented or superseded from time to time).
Events of default and acceleration:	If the Trigger Participation Securities have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the Trigger 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 Trigger Participation Securities linked to the underlying index. The purchaser of a Trigger Participation Security will acquire a senior unsecured debt security of HSBC USA Inc. Although the offering of Trigger 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 Trigger 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.
