HSBC USA Inc. Trigger Performance Securities

Linked to an International Fund Basket due on or about May 31, 2016

Investment Description

These Trigger Performance Securities (the “Securities”) are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”) with returns linked to the performance of a weighted Basket of exchange traded funds (weighted as described herein), which we refer to as the “Basket,” consisting of the iShares® MSCI EAFE Index Fund (“EFA”) and the iShares® MSCI Emerging Markets Index Fund (“EEM”), each of which we refer to as an “index fund,” and together, the “index funds.” The Securities will rank equally with all of our other unsecured and unsubordinated debt obligations. If the Basket Return is greater than zero, HSBC will repay the Principal Amount at maturity plus pay a return equal to the product of (i) the Principal Amount multiplied by (ii) the Basket Return multiplied by the Participation Rate of between 102.00% and 110.00% (the actual Participation Rate will be determined on the Trade Date). If the Basket Return is less than or equal to zero, HSBC will either repay the full Principal Amount at maturity or, if the Basket Ending Level is less than the Trigger Level, you will be fully exposed to the Basket's decline and HSBC will pay less than the full Principal Amount at maturity, if anything, resulting in a loss to investors that is proportionate to the negative Basket Return. Investing in the Securities involves significant risks. You will not receive interest or dividend payments during the term of the Securities. You may lose some or all of your Principal Amount. The contingent repayment of principal applies only if you hold the Securities to maturity. Any payment on the Securities, including any contingent repayment of principal at maturity, is subject to the creditworthiness of HSBC. If HSBC were to default on its payment obligations, you may not receive any amounts owed to you under the Securities and you could lose your entire investment.

Features

Participation in Positive Basket Returns: If the Basket Return is greater than zero, HSBC will repay the Principal Amount at maturity plus pay a return equal to the Basket Return multiplied by the Participation Rate. If the Basket Return is less than or equal to zero, investors may be exposed to the negative Basket Return at maturity.

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

THE SECURITIES ARE SIGNIFICANTLY RISKIER THAN CONVENTIONAL DEBT INSTRUMENTS. THE TERMS OF THE SECURITIES MAY NOT OBLIGATE HSBC TO REPAY THE FULL PRINCIPAL AMOUNT OF THE SECURITIES. THE SECURITIES CAN HAVE DOWNSIDE MARKET RISK SIMILAR TO THE INDEX FUNDS AND RESULTING BASKET, WHICH CAN RESULT IN A LOSS OF SOME OR ALL OF YOUR INVESTMENT AT MATURITY. THIS MARKET RISK IS IN ADDITION TO THE CREDIT RISK INHERENT IN PURCHASING A DEBT OBLIGATION OF HSBC. YOU SHOULD NOT PURCHASE THE SECURITIES IF YOU DO NOT UNDERSTAND OR ARE NOT COMFORTABLE WITH THE SIGNIFICANT RISKS INVOLVED IN INVESTING IN THE SECURITIES.

YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED UNDER ‘‘KEY RISKS’’ BEGINNING ON PAGE 6 OF THIS FREE WRITING PROSPECTUS AND THE MORE DETAILED ‘‘RISK FACTORS’’ BEGINNING ON PAGE US4-2 OF THE ACCOMPANYING UNDERLYING SUPPLEMENT NO. 4 AND BEGINNING ON PAGE S-3 OF THE ACCOMPANYING PROSPECTUS SUPPLEMENT BEFORE PURCHASING ANY SECURITIES. EVENTS RELATING TO ANY OF THOSE RISKS, OR OTHER RISKS AND UNCERTAINTIES, COULD ADVERSELY EFFECT THE MARKET VALUE OF, AND THE RETURN ON, YOUR SECURITIES.

Additional Information about HSBC USA Inc. and the Securities

This free writing prospectus relates to the offering of Securities linked to the Basket identified on the cover page. The Basket described in this free writing prospectus is a reference asset as defined in the underlying supplement no. 4 and the prospectus supplement, and the Securities being offered hereby are “notes” for purposes of the underlying supplement no. 4 and the prospectus supplement. As a purchaser of a Security, you will acquire a senior unsecured debt instrument linked to the Basket that will rank equally with all of our other unsecured and unsubordinated debt obligations. Although the offering of Securities relates to the Basket identified on the cover page, you should not construe that fact as a recommendation of the merits of acquiring an investment linked to the Basket, any index fund or index underlying any index fund (each an “Underlying Index” and together the “underlying indices”), or any stocks comprising an Underlying Index, or as to the suitability of an investment in the Securities. Your investment is linked to a Basket that consists of the index funds and is not linked to any Underlying Index.

You should read this document together with the prospectus dated April 2, 2009, the prospectus supplement dated April 9, 2009 and the underlying supplement no. 4 dated October 22, 2010.

You should carefully consider, among other things, the matters set forth in “Key Risks” on page 6 of this free writing prospectus and in “Risk Factors” beginning on page US4-2 of the underlying supplement no. 4 and beginning on page S-3 of the prospectus supplement, as the Securities involve risks not associated with conventional debt securities. You are urged to consult your investment, legal, tax, accounting and other advisors before you invest in the Securities.

Investor Suitability
The Securities may be suitable for you if: ¨ You fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ¨ You can tolerate a loss of all or a substantial portion of your investment and are willing to make an investment that may have similar downside market risk as an investment in the Index Funds included in the Basket. ¨ You are willing to hold the Securities to maturity, a term of 5 years, and accept that there may be little or no secondary market for the Securities. ¨ You believe the Basket will appreciate over the term of the Securities and you would be willing to invest in the Securities if the Participation Rate was set equal to the bottom of the range indicated on the cover hereof (the actual Participation Rate will be set on the Trade Date). ¨ You do not seek current income from your investment and are willing to forego dividends paid on the Index Funds included in the Basket. ¨ You are comfortable with the creditworthiness of HSBC, as Issuer of the Securities, and understand that if HSBC defaults on its obligations you may not receive any amounts due to you including any repayment of principal.		The Securities may not be suitable for you if: ¨ You do not fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment. ¨ You cannot tolerate a loss of all or a substantial portion of your investment, and you are not willing to make an investment that may have similar downside market risk as an investment in the Index Funds included in the Basket. ¨ You believe that the level of the Basket will decline during the term of the Securities and is likely to close below the Trigger Level on the final valuation date. ¨ You require an investment designed to provide a full return of principal at maturity. ¨ You prefer the lower risk, and therefore accept the potentially lower returns, of conventional debt securities with comparable maturities issued by HSBC or another issuer with a similar credit rating. ¨ You seek current income from your investment or prefer to receive the dividends paid on the Index Funds included in the Basket. ¨ You are unable or unwilling to hold the Securities to maturity, a term of 5 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.

The suitability considerations identified above are not exhaustive. Whether or not the Securities are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the suitability of an investment in the Securities in light of your particular circumstances. You should also review “Key Risks” on page 6 of this free writing prospectus and “Risk Factors” on page US4-2 of the underlying supplement no. 4 and on page S-3 of the prospectus supplement.

What are the tax consequences of the Securities?

You should carefully consider, among other things, the matters set forth in the section “Certain U.S. Federal Income Tax Considerations” in the prospectus supplement. The following discussion summarizes certain of the material U.S. federal income tax consequences of the purchase, beneficial ownership, and disposition of each of the Securities. This summary supplements the section “Certain U.S. Federal Income Tax Considerations” in the prospectus supplement and supersedes it to the extent inconsistent therewith. This summary does not address the tax consequences that may be relevant to persons that own in the aggregate, directly or indirectly (including by reason of investing in the Securities), more than 5% of any index fund or any entity owned by the index funds. Notwithstanding any disclosure in the accompanying prospectus supplement to the contrary, HSBC’s special U.S. tax counsel in this transaction is Sidley Austin llp.

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 forward or other executory contracts with respect to the Basket. 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 prospectus supplement, and based on certain factual representations received from HSBC, in the opinion of HSBC’s special U.S. tax counsel, Sidley Austin llp, it is reasonable to treat the Securities in accordance with this approach. Pursuant to this approach, and subject to the discussion below regarding “constructive ownership transactions”, HSBC does not intend to report any income or gain with respect to the Securities prior to their maturity or an earlier sale or exchange and HSBC intends to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Security for more than one year at such time for U.S. federal income tax purposes. See “Certain 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 forward or other executory contracts.

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

Although the matter is not clear, there exists a risk that an investment in the Securities will be treated as a “constructive ownership transaction.” If such treatment applies, it is not entirely clear to what extent any long-term capital gain recognized by a U.S. holder in respect of a Security will be recharacterized as ordinary income. Accordingly, U.S. holders should consult their tax advisors regarding the potential application of the “constructive ownership” rules.

HSBC will not attempt to ascertain whether the issuer of any stock owned by one or more of the index funds would be treated as a passive foreign investment company (“PFIC”), as defined for U.S. federal income tax purposes. In the event that the issuer of any stock owned by one or more of the index funds were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the issuers of stock owned by the index funds and consult your tax advisor regarding the possible consequences to you in the event that one or more issuers of stock owned by one or more of the index funds is or becomes a PFIC.

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 “Certain 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 of a Security is required to accrue income in respect of the Securities prior to the receipt of payments with respect to the Securities or their 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 the Securities as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder (as defined under “Certain U.S. Federal Income Tax Considerations” in the prospectus supplement) of the Securities could be subject to U.S. withholding tax in respect of the Securities. 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.

Key Risks

An investment in the Securities involves significant risks. Some of the risks that apply to the Securities are summarized here, but you are urged to read the more detailed explanation of risks relating to the Securities generally in the “Risk Factors” section of the accompanying underlying supplement no. 4 and the accompanying prospectus supplement. You are also urged you to consult your investment, legal, tax, accounting and other advisors before you invest in the Securities.

Risk of Loss at Maturity – The Securities differ from ordinary debt securities in that HSBC will not necessarily pay the full Principal Amount of the Securities at maturity. The return on the Securities at maturity is linked to the performance of the Basket and will depend on whether, and to the extent which, the Basket Return is positive or negative and if the Basket Return is negative, whether the Basket Ending Level is less than the Trigger Level. If the Basket Ending Level is less than the Trigger Level, you will be fully exposed to any negative Basket Return and HSBC will pay you less than your initial investment, if anything, resulting in a loss that is proportionate to the decline in the Basket Ending Level as compared to the Basket Starting Level. Under these circumstances, you will lose a significant portion, and could lose all, of your initial investment.

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 level of the Basket at the time of sale is above the Trigger Level.

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 Basket's return even if such return is positive. You can receive the full benefit of the Participation Rate from HSBC only if you hold your Securities to maturity.

Certain Built-in Costs are Likely to Adversely Affect the Value of the Securities Prior to Maturity – You should be willing to hold your Securities to maturity. The Securities are not designed to be short-term trading instruments. The price at which you will be able to sell your Securities to HSBC, its affiliates or any party in the secondary market prior to maturity, if at all, may be at a substantial discount from the Principal Amount of the Securities, even in cases where the Basket has appreciated since the Trade Date.

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

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

No Dividend Payments or Voting Rights – Owning the Securities is not the same as owning the index funds or the stocks comprising each index fund’s Underlying 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 shares of the index funds or stocks held by the index funds would have.

Price Prior to Maturity – The market price of the Securities will be influenced by many factors including the price of the index funds, price volatilities, dividends, the time remaining to maturity of the Securities, interest rates, geopolitical conditions, economic, political, regulatory or judicial events, and the creditworthiness of HSBC.

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 HSBC is unable to pay its obligations when due, you may not receive any amounts owed to you under the Securities.

Lack of Liquidity – The Securities will not be listed on any securities exchange or quotation system. One of our affiliates may offer to repurchase the Securities in the secondary market but is not required to do so and may cease any such market-making activities at any time without notice. Because other dealers are not likely to make a secondary market for the Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which one of our affiliates is willing to buy the Securities, which will exclude any fees or commissions you paid when you purchased the Securities.

Impact of Fees on Secondary Market Prices – Generally, the price of the Securities in the secondary market 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.

Potential Conflict of Interest – HSBC or its affiliates may engage in business with the issuers of the stocks comprising an Underlying Index, which may present a conflict between the obligations of HSBC and you, as a holder of the Securities. The Calculation Agent, which may be HSBC or any of its affiliates, will determine the Payment at Maturity based on the observed Basket Ending Level. The Calculation Agent can postpone the determination of the Basket Ending Level or the maturity date if a market disruption event occurs and is continuing on the final valuation date.

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

An Index Fund and its Underlying Index are Different – The performance of an index fund may not exactly replicate the performance of the respective Underlying Index, because such index fund will reflect transaction costs and fees that are not included in the calculation of the respective Underlying Index. It is also possible that an index fund may not fully replicate or may in certain circumstances diverge significantly from the performance of the respective Underlying Index due to the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments contained in such fund or due to other circumstances. An index fund may use futures contracts, options, swap agreements, currency forwards and repurchase agreements in seeking performance that corresponds to the respective Underlying Index and in managing cash flows. Your investment is linked to the

Basket which consists of the index funds. Any information relating to the relevant Underlying Index is only relevant to understanding the index that the relevant index fund seeks to replicate.

Management Risk – The index funds are not managed according to traditional methods of ‘‘active’’ investment management, which involve the buying and selling of securities based on economic, financial and market analysis and investment judgment. Instead, the index funds, utilizing a ‘‘passive’’ or indexing investment approach, attempt to approximate the investment performance of their respective Underlying Index by investing in a portfolio of securities that generally replicate the respective Underlying Index. Therefore, unless a specific security is removed from the respective Underlying Index, an index fund generally would not sell a security because the security’s issuer was in financial trouble. In addition, an index fund is subject to the risk that the investment strategy of the fund’s investment adviser may not produce the intended results. Your investment is linked to the Basket which consists of the index funds. Any information relating to the relevant Underlying Index is only relevant to understanding the index that the relevant index fund seeks to replicate.

There is Limited Anti-dilution Protection – The Calculation Agent will adjust the Final Value of an index fund, which will affect the Basket Return and, consequently, the Payment at Maturity, for certain events affecting the shares of such index fund, such as stock splits and corporate actions. The Calculation Agent is not required to make an adjustment for every corporate action which affects the shares of the index funds. If an event occurs that does not require the Calculation Agent to adjust the prices of the shares of the index funds, the market price of the Securities may be materially and adversely affected. See “Antidilution and Reorganization Adjustments” in the accompanying underlying supplement no. 4 for additional information.

Changes in the Value of One or More Index Funds May Offset Each Other – Price movements in the index funds may not correlate with each other. Even if the value of one of the index funds increases, the value of the other index fund may not increase as much or may even decrease. Therefore, in calculating the Basket Ending Level, increases in the value of one of the index funds may be moderated, or wholly offset, by lesser increases or declines in the value of the other index fund.

HSBC Cannot Control Actions by the Companies Whose Stocks or Other Equity Securities are Held By the Index Funds – Our affiliate, HSBC Holdings plc, is one of the companies whose stock is held by the EFA and is one of the companies that make up its Underlying Index. HSBC is not affiliated with any of the other companies whose stock is held by the index funds. HSBC will have no ability to control the actions of HSBC Holdings plc or any of such other companies, including its affiliate, including actions that could affect the value of the stocks held by the index funds, or your Securities. None of the money you pay HSBC will go to any of the companies whose stock is held by the index funds, and none of those companies will be involved in the offering of the Securities in any way. Those companies will have no obligation to consider your interests as a holder of the Securities in taking any corporate actions that might affect the value of your Securities.

The Securities are Subject to Risks Associated with Foreign Securities Markets – Because foreign companies or foreign equity securities held by EFA and EEM 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.

The Securities are Subject to Emerging Markets Risk — Investments in securities linked directly or indirectly to emerging market equity securities, such as the EEM, involve many risks, including, but not limited to: economic, social, political, financial and military conditions in the emerging market; regulation by national, provincial, and local governments; less liquidity and smaller market capitalizations than exist in the case of many large U.S. companies; different accounting and disclosure standards; and political uncertainties. Stock prices of emerging market companies may be more volatile and may be affected by market developments differently than U.S. companies. Government interventions to stabilize securities markets and cross-shareholdings may affect prices and volume of trading of the securities of emerging market companies. Economic, social, political, financial and military factors could, in turn, negatively affect such companies’ value. These factors could include changes in the emerging market government’s economic and fiscal policies, possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to the emerging market companies or investments in their securities, and the possibility of fluctuations in the rate of exchange between currencies. Moreover, emerging market economies may differ favorably or unfavorably from the U.S. economy in a variety of ways, including growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency. You should carefully consider the risks related to emerging markets, to which the Securities are highly susceptible, before making a decision to invest in the Securities.

Exchange Rate Risk – Because EFA and EEM will hold stocks denominated in foreign currencies, changes in currency exchange rates may negatively impact such index funds’ returns. The values of the foreign currencies 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. Therefore, exposure to exchange rate risk may result in reduced returns to EFA and EEM.

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; 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 credit worthiness of HSBC.

Potential HSBC Impact on Price – Trading or transactions by HSBC USA Inc. or any of its affiliates in the stocks held by the index funds or in shares of the index funds, or in futures, options, exchange-traded funds or other derivative products on the stocks held by the index funds or shares of the index funds, may adversely affect the market value of the stocks held by the index funds or shares of the index funds, and, therefore, the market value of the Securities.

Uncertain Tax Treatment – There is no direct legal authority as to the proper tax treatment of the Securities, and therefore significant aspects of the tax treatment of the Securities are uncertain as to both the timing and character of any inclusion in income in respect of the Securities. Under one reasonable approach, the Securities should be treated as pre-paid forward or other executory contracts with respect to the Basket. 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. See “Certain 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 forward or other executory contracts.

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

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

Scenario Analysis and Examples at Maturity

The below scenario analysis and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the level of the Basket relative to the Basket Starting Level. We cannot predict the Basket Ending Level on the Final Valuation Date. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Basket. The numbers appearing in the examples below have been rounded for ease of analysis. The following scenario analysis and examples illustrate the payment at maturity for a $10.00 security on a hypothetical offering of the Securities, with the following assumptions*:

Investment term:	5 years

Basket Starting Level:	100.00

Trigger Level:	55.00 (55% of the Basket Starting Level)

Hypothetical Participation Rate:	106.00% (the midpoint of the range of 102.00% to 110.00%)

* The actual Participation Rate for the Securities will be determined on the Trade Date.

Example 1— The level of the Basket increases from a Basket Starting Level of 100.00 to a Basket Ending Level of 110.00. The Basket Return is greater than zero and expressed as a formula:

Basket Return = (110.00 - 100.00) / 100.00 = 10.00%

Payment at Maturity = $10 + ($10 × (10.00% × 106.00%)) = $11.06

Because the Basket Return is equal to 10.00%, the Payment at Maturity is equal to $11.06 per $10.00 Principal Amount of Securities, and the return on the Securities is 10.60%.

Example 2— The Basket Ending Level is equal to the Basket Starting Level of 100.00. The Basket Return is zero and expressed as a formula:

Basket Return = (100 – 100) / 100 = 0.00%

Payment at Maturity = $10.00

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

Example 3— The level of the Basket decreases from a Basket Starting Level of 100.00 to a Basket Ending Level of 70.00. The Basket Return is negative and expressed as a formula:

Basket Return = (70.00 - 100.00) / 100.00 = -30.00%

Payment at Maturity = $10.00

Because the Basket Return is less than zero, but the Basket Ending Level is greater than or equal to the Trigger Level on the Final Valuation Date, HSBC will pay you a Payment at Maturity equal to $10.00 per $10.00 Principal Amount of Securities (a zero return).

Example 4— The level of the Basket decreases from a Basket Starting Level of 100.00 to a Basket Ending Level of 40.00. The Basket Return is negative and expressed as a formula:

Basket Return = (40.00 - 100.00) / 100.00 = -60.00%

Payment at Maturity = $10 + ($10 × -60.00%) = $4.00

Because the Basket Return is less than zero and the Basket Ending Level is below the Trigger Level on the Final Valuation Date, the Securities will be fully exposed to any decline in the level of the Basket on the Final Valuation Date. Therefore, the return on the Securities is -60.00%. In this case, you would incur a loss of 60% on your Securities.

If the Basket Ending Level is below the Trigger Level on the Final Valuation Date, the Securities will be fully exposed to any decline in the Basket, and you will lose some or all of your Principal Amount at maturity.

Scenario Analysis – hypothetical Payment at Maturity for each $10.00 Principal Amount of Securities.

Events of Default and Acceleration

If the Securities have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the Securities, the Calculation Agent will determine the accelerated payment due and payable at maturity in the same general manner as described in “Indicative Terms” in this free writing prospectus. In that case, the scheduled trading day preceding the date of acceleration will be used as the final valuation date for purposes of determining the Basket Ending Level. If a market disruption event exists with respect to an index fund on that scheduled trading day, then the accelerated final valuation date for such index fund will be postponed for up to five scheduled trading days (in the same manner used for postponing the originally scheduled final valuation date). The accelerated maturity date will then be the fourth business day following the postponed accelerated final valuation date. For the avoidance of doubt, if no market disruption event exists with respect to an index fund on the scheduled trading day preceding the date of acceleration, the determination of such index fund’s Final Value will be made on such date, irrespective of the existence of a market disruption event with respect to one or more of the other index funds occurring on such date.

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 — Events of Default” and “— Events of Default; Defaults” in the prospectus.

Supplemental Plan of Distribution (Conflicts of Interest)

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc., an affiliate of HSBC, will purchase the Securities from HSBC for distribution to UBS Financial Services Inc. (the “Agent”), HSBC will agree to sell to the Agent, and the Agent will agree to purchase, all of the Securities at the price indicated on the cover of the pricing supplement, which is the document that will be filed pursuant to Rule 424(b)(2) containing the final pricing terms of the Securities. HSBC has agreed to indemnify the Agent against liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Agent may be required to make relating to these liabilities as described in the prospectus supplement and the prospectus. The Agent may allow a concession not in excess of the underwriting discount set forth on the cover of this free writing prospectus to its affiliates.

Subject to regulatory constraints, HSBC USA Inc. (or an affiliate thereof) intends to offer to purchase the Securities in the secondary market, but is not required to do so and may cease making such offers at any time. HSBC or its affiliate will enter into swap agreements or related hedge transactions with one of its other affiliates or unaffiliated counterparties, which may include the Agent, in connection with the sale of the Securities and the Agent and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions.
