HSBC USA Inc. Airbag Performance Securities

$878,000 Linked to the S&P 500^® Index due September 30, 2022

Investment Description

These Airbag Performance Securities Linked to the S&P 500^® Index (the "Index") are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”), which we refer to as the “Securities”. The Securities will rank equally with all of our other unsecured and unsubordinated debt obligations. If the Index Return is positive, HSBC will repay the Principal Amount at maturity plus a return equal to the Index Return times the Participation Rate of 187.50%. If the Index Return is zero or negative but greater than or equal to the Threshold Percentage, HSBC will repay the full Principal Amount at maturity. However, if the Index Return is negative and is less than the Threshold Percentage, HSBC will pay less than the full Principal Amount at maturity, if anything, resulting in a loss of 2% of principal for each 1% that the Index Return is less than -50%, up to a loss of your entire investment. Investing in the Securities involves significant risks. HSBC will not pay any interest on the Securities. You may lose some or all of your Principal Amount. The contingent repayment of principal only applies if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of HSBC. If HSBC were to default on its payment obligations you may not receive any amounts owed to you under the Securities and you could lose your entire investment.

Features

q Participation in Positive Index Returns: If the Index Return is greater than zero, HSBC will repay your Principal Amount at maturity plus a return equal to the Index Return multiplied by the Participation Rate. If the Index Return is less than zero, investors may be exposed to the downside market risk of the Index at maturity.

q Contingent Repayment of Principal at Maturity: If the Index Return is zero or negative, but is greater than or equal to the Threshold Percentage, HSBC will repay your Principal Amount at maturity. However, if the Index Return is less than the Threshold Percentage, HSBC will pay less than the full Principal Amount at maturity, if anything, resulting in a loss of 2% of the Principal Amount for each 1% that the Index Return is less than -50%, up to a loss of your entire investment. The contingent repayment of principal applies only if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of HSBC.

The Securities may not be suitable for you if: ¨You do not fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ¨You cannot tolerate a loss of all or a substantial portion of your investment and are unwilling to make an investment that can have up to the full downside market risk of the Index. ¨You seek an investment that provides a full return of principal at maturity. ¨You believe that the level of the Index will decline during the term of the Securities and that the Index Return is likely to be below the Threshold Percentage on the Final Valuation Date. ¨You are unwilling to invest in the Securities based on the Participation Rate of 187.50%. ¨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 that would pay interest at prevailing market rates. ¨You seek current income from this investment or prefer to receive the dividends paid on the stocks included in the Index. ¨You are unable or unwilling to hold the Securities to maturity, a term of approximately ten years, or you seek an investment for which there will be an active secondary market. ¨You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Securities, for any payment on the Securities, including any repayment of principal.

Investment Timeline

 

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

Key Risks

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

¨ Your Investment in the Securities May Result in a Loss – The Securities differ from ordinary debt securities in that the Issuer will not necessarily pay the full Principal Amount of the Securities at maturity. HSBC will only pay you the Principal Amount of your Securities in cash if the Index Return is greater than or equal to the Threshold Percentage and only at maturity. If the Index Return is below the Threshold Percentage of -50%, you will lose 2% of the Principal Amount for each 1% that the Index Return is less than -50%. Accordingly, if the Index Return is below the Threshold Percentage, the amount of cash you receive will be less than the Principal Amount resulting in a loss of some or all of the Principal Amount.

¨ The Contingent Repayment of Principal Applies Only if You Hold the Securities to Maturity – You should be willing to hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, you may have to sell them at a loss relative to your initial investment even if the return of the Index at that time is above the Threshold Percentage.

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

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

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

¨ The Securities Lack Liquidity – The Securities will not be listed on any securities exchange or quotation system. An affiliate of HSBC intends to offer to repurchase the Securities in the secondary market but is not required to do so and may cease any such market-making activities at any time without notice. Because other dealers are not likely to make a secondary market for the Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which an affiliate of HSBC is willing to buy the Securities. The price, if any, will exclude any fees or commissions paid by brokerage account holders when the Securities were purchased and therefore will generally be lower than such purchase price.

¨ Owning the Securities Is Not the Same as Owning the Stocks Comprising the Index – The return on your Securities may not reflect the return you would realize if you actually owned the stocks included in the Index. As a holder of the Securities, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the stocks included in the Index would have.

¨ Market Price Prior to Maturity – The market price of the Securities will be influenced by many unpredictable and interrelated factors, including the level of the Index; the volatility of the Index; dividends paid on the stocks included in the Index; the time remaining to the maturity of the Securities; interest rates in the markets in general; geopolitical conditions and economic, financial, political, regulatory, judicial or other events; and the creditworthiness of HSBC.

¨ The Securities Are Subject to Risks Associated with Foreign Securities Markets – Because foreign companies may be included in the Index, which may be publicly traded in the applicable foreign countries and are denominated in currencies other than U.S. dollars, investments in the Securities involve particular risks. For example, the foreign securities markets may be more volatile than the U.S. securities markets, and market developments may affect these markets differently from the United States or other securities markets. Direct or indirect government intervention to stabilize the securities markets outside the United States, as well as cross-shareholdings in certain companies, may affect trading prices and trading volumes in those markets. Also, the public availability of information concerning the foreign issuers may vary depending on their home jurisdiction and the reporting requirements imposed by their respective regulators. In addition, the foreign issuers may be subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to United States reporting companies.

Securities prices generally are subject to political, economic, financial and social factors that apply to the markets in which they trade and, to a lesser extent, foreign markets. Securities prices outside the United States are subject to political, economic, financial and social factors that apply in foreign countries. These factors, which could negatively affect foreign securities markets, include the possibility of changes in a foreign government’s economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities and the possibility of fluctuations in the rate of exchange between currencies. Moreover, foreign economies may differ favorably or unfavorably from the United States economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

4

¨ Exchange Rate Risk – The Index may include stocks that are issued by foreign companies that also issue equity securities denominated in foreign currencies. The value of such stocks may be subject to a high degree of fluctuation due to changes in interest rates, the effects of monetary policies issued by the United States, foreign governments, central banks or supranational entities, the imposition of currency controls or other national or international political or economic developments. However, the value of your Securities will not be adjusted for exchange rate fluctuations between the U.S. dollar and the currencies in which the stocks composing the Index are based. Therefore, if the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the Securities, you will not receive any additional payment or incur any reduction in your return, if any, at maturity.

¨ Impact of Fees and Hedging Costs on Secondary Market Prices – Generally, the price of the Securities in the secondary market, if any, is likely to be lower than the initial offering price since the issue price includes, and the secondary market prices are likely to exclude commissions, hedging costs or other compensation paid with respect to the Securities.

¨ Changes Affecting the Index – The policies of the reference sponsor concerning additions, deletions and substitutions of the stocks included in the Index and the manner in which the reference sponsor takes account of certain changes affecting those stocks included in the Index may adversely affect the level of the Index. The policies of the reference sponsor with respect to the calculation of the Index could also adversely affect the level of the Index. The reference sponsor may discontinue or suspend calculation or dissemination of the Index. Any such actions could have an adverse effect on the value of the Securities.

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

¨ Potential Conflict of Interest – HSBC, UBS Financial Services Inc., or any of their respective affiliates may engage in business with the issuers of the stocks comprising the Index, which could affect the price of such stocks or the level of the Index and thus, may present a conflict between the obligations of HSBC and you, as a holder of the Securities. Additionally, potential conflicts of interest may exist between the Calculation Agent, which may be HSBC or any of its affiliates, and you with respect to certain determinations and judgments that the Calculation Agent must make, which include determining the Payment at Maturity based on the Final Level as well as whether to postpone the determination of the Final Level and the Maturity Date if a Market Disruption Event occurs and is continuing on the Final Valuation Date.

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

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

¨ Uncertain Tax Treatment – Significant aspects of the tax treatment of the Securities are uncertain. You should consult your tax advisor about your own tax situation. See “What Are the Tax Consequences of the Securities?” beginning on page 8.

Scenario Analysis and Examples at Maturity

The scenario analysis and examples below are provided for illustrative purposes only and are purely hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the level of the Index relative to the Initial Level. We cannot predict the Final Level. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Index. The numbers set forth in the examples below have been rounded for ease of analysis. The following scenario analysis and examples illustrate the Payment at Maturity for a $1,000 Principal Amount of Securities.

Term:	10 years
Principal Amount:	$1,000
Initial Level:	1,441.59
Threshold Percentage:	-50%
Participation Rate:	187.50%
Threshold Multiplier:	2

Example 1: The Final Level is 1,585.75 for an Index Return of 10%.

Since the Index Return is positive, the Payment at Maturity per Security will be calculated as follows:

$1,000 + ($1,000 × 10% × 187.50%) = $1,187.50 per Security

Example 2: The Final Level is 1,009.11 for an Index Return of -30%.

Since the Index Return is negative but greater than the Threshold Percentage of -50%, HSBC will repay the full Principal Amount and the Payment at Maturity is equal to $1,000 per Security (a zero percent return).

Example 3: The Final Level is 576.64 for an Index Return of -60%.

Since the Index Return is negative and less than the Threshold Percentage of -50%, the Securities will be exposed to the negative Index Return beyond the Threshold Percentage multiplied by the Threshold Multiplier. Therefore, the Payment at Maturity per Security will be calculated as follows:

$1,000 + [$1,000 × (-60% + 50%) × 2] = $800 per Security

If the Index Return is below the Threshold Percentage on the Final Valuation Date, your investment in the Securities will be exposed to the downside market risk of the Index and you will lose some or all of your principal at maturity.

What are the tax consequences of the Securities?

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

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Securities. Under one reasonable approach, the Securities should be treated as pre-paid executory contracts with respect to the Index. HSBC intends to treat the Securities consistent with this approach and pursuant to the terms of the Securities, you agree to treat the Securities under this approach for all U.S. federal income tax purposes. Subject to certain limitations described in the accompanying prospectus supplement, and based on certain factual representations received from HSBC, in the opinion of HSBC’s special U.S. tax counsel, Morrison & Foerster LLP, it is reasonable to treat the Securities in accordance with this approach. Pursuant to this approach, HSBC does not intend to report any income or gain with respect to the Securities prior to their maturity or an earlier sale or exchange and HSBC intends to treat any gain or loss upon maturity or such earlier sale or exchange as long-term capital gain or loss, provided that you have held the Security for more than one year at such time for U.S. federal income tax purposes. See "U.S. Federal Income Tax Considerations — Certain Equity-Linked Notes — Certain Notes Treated as Forward Contracts or Executory Contracts" in the prospectus supplement for certain U.S. federal income tax considerations applicable to Securities that are treated as pre-paid cash-settled executory contracts.

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

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

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

The S&P 500^® Index

Events of Default and Acceleration

If the Securities have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the Securities, the Calculation Agent will determine the accelerated Payment at Maturity due and payable in the same general manner as described in “Final Terms” in this pricing supplement. In that case, the scheduled trading day preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the accelerated Index Return. If a market disruption event exists on that scheduled trading day, then the accelerated Final Valuation Date will be postponed for up to five scheduled trading days (in the same general manner used for postponing the originally scheduled Final Valuation Date). The accelerated Maturity Date will also be postponed by an equal number of business days.

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

We or our affiliate will enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties, which may include the Agent, in connection with the sale of the Securities and the Agent and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions.
