Key Investment Rationale

The Buffered PLUS offer 200% leveraged upside on the positive performance of the underlying shares, subject to a maximum payment at maturity of $11.80 to $12.20 per Buffered PLUS (118% to 122% of the stated principal amount), and provide a buffer against a decline of 10% in the underlying shares, ensuring a minimum payment of $1.00 per Buffered PLUS at maturity subject to the credit risk of HSBC.

Leveraged Performance	The Buffered PLUS offer investors an opportunity to capture enhanced returns for a certain range of positive performance relative to a direct investment in the underlying shares.
Payment Scenario 1	The underlying shares increase in price and, at maturity, the Buffered PLUS redeem for the stated principal amount of $10 plus 200% of the share percent increase, subject to a maximum payment at maturity of $11.80 to $12.20 per Buffered PLUS (118% to 122% of the stated principal amount).
Payment Scenario 2	The underlying shares decline in price by no more than 10% and, at maturity, the Buffered PLUS redeem for the stated principal amount of $10.
Payment Scenario 3	The underlying shares decline in price by more than 10% and, at maturity, the Buffered PLUS redeem for less than the stated principal amount by an amount that is proportionate to the percentage decrease of the underlying shares from the initial share price, plus the buffer amount of 10%.  (Example: if the underlying shares decrease in price by 20%, the Buffered PLUS will redeem for $9.00, or 90% of the stated principal amount.)  The minimum payment at maturity is $1.00 per Buffered PLUS subject to the credit risk of HSBC.

General Information
Listing:	The Buffered PLUS will not be listed on any securities exchange.
CUSIP:	40433K579
ISIN:	US40433K5790
Minimum ticketing size:	100 Buffered PLUS
Tax considerations:	There is no direct legal authority as to the proper tax treatment of each Buffered PLUS, and therefore significant aspects of the tax treatment of each Buffered PLUS is uncertain as to both the timing and character of any inclusion in income in respect of each Buffered PLUS. Under one approach, each Buffered PLUS could be treated as a pre-paid forward or other executory contract with respect to the underlying shares. We intend to treat each Buffered PLUS consistent with this approach. Pursuant to the terms of each Buffered PLUS, you agree to treat each Buffered PLUS under this approach for all U.S. federal income tax purposes. Notwithstanding any disclosure in the accompanying product supplement to the contrary, our special U.S. tax counsel in this transaction is Sidley Austin llp. 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, Sidley Austin llp, it is reasonable to treat each Buffered PLUS as a pre-paid forward or other executory contract with respect to the underlying shares. Pursuant to this approach and subject to the discussion below regarding “constructive ownership transactions,” we do not intend to report any income or gain with respect to each Buffered PLUS prior to maturity or an earlier sale or exchange and we intend to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Buffered PLUS for more than one year at such time for U.S. federal income tax purposes. Despite the foregoing, U.S. holders (as defined under “Certain U.S. Federal Income Tax Considerations” in the accompanying 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 iShares® MSCI Emerging Markets Index Fund (the “Underlying Shares”)). Under the “constructive ownership” rules, if an investment in a Buffered PLUS is treated as a “constructive ownership transaction,” any long-term capital gain recognized by a U.S. holder in respect of the Buffered PLUS 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 determined as if the U.S. holder had acquired the Underlying Shares on the original issue date of the Buffered PLUS at fair market value and sold them at fair market value on the maturity date (if the Buffered PLUS was held until the maturity date) or on the date of sale or exchange of the Buffered PLUS (if the Buffered PLUS was sold or exchanged prior to the maturity date) (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 Buffered PLUS (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 Buffered PLUS). Although the matter is not clear, there exists a risk that an investment in a Buffered PLUS 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 Buffered PLUS will be recharacterized as ordinary income. It is possible, for example, that the amount of the Excess Gain (if any) that would be recharacterized as ordinary income in respect of each Buffered PLUS will equal the excess of (i) any long-term capital gain recognized by the U.S. holder in respect of such a Buffered PLUS over (ii) the “net underlying long-term capital gain” such U.S. holder would have had if such U.S. holder had acquired a number of the Underlying Shares at fair market value on the original issue date of such Buffered PLUS for an amount equal to the “issue price” of the Buffered PLUS and, upon the date of sale, exchange or maturity of the Buffered PLUS, sold such Underlying Shares at fair market value (which would reflect the percentage increase in the value of the Underlying Shares over the term of the Buffered PLUS). Accordingly, U.S. holders should consult their tax advisors regarding the potential application of the “constructive ownership” rules. We will not attempt to ascertain whether any of the entities whose stock is owned by the iShares® MSCI Emerging Markets Index Fund would be treated as a passive foreign investment company (“PFIC”), as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is owned by the iShares® MSCI Emerging Markets Index Fund were so treated, certain adverse U.S. federal income tax consequences might apply to U.S. holders. You should refer to information filed with the SEC and other authorities by the entities whose stock is or owned by the iShares® MSCI Emerging Markets Index Fund and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is owned by the iShares® MSCI Emerging Markets Index Fund is or becomes a PFIC. In Notice 2008-2, the Internal Revenue Service and the Treasury Department requested comments as to whether the purchaser of certain securities (which may include the Buffered PLUS) 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

Buffered PLUS Based on the Value of the iShares^® MSCI Emerging Markets Index Fund due August 29, 2013

Buffered Performance Leveraged Upside Securities^SM

	possible that regulations or other guidance could provide that a U.S. holder (as defined in the accompanying product supplement) of a Buffered PLUS is required to accrue income in respect of the Buffered PLUS prior to the receipt of payments under the Buffered PLUS 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 Buffered PLUS as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder (as defined in the accompanying product supplement) of the Buffered PLUS could be subject to U.S. withholding tax in respect of a Buffered PLUS. It is unclear whether any regulations or other guidance would apply to the Buffered PLUS (possibly on a retroactive basis). Prospective investors are urged to consult with their tax advisors regarding Notice 2008-2 and the possible effect to them of the issuance of regulations or other guidance that affects the U.S. federal income tax treatment of the Buffered PLUS. For a further discussion of the U.S. federal income tax consequences related to each Buffered PLUS, see the section “Certain U.S. Federal Income Tax Considerations” in the accompanying product supplement.
Trustee:	Notwithstanding anything contained in the accompanying prospectus supplement to the contrary, the Buffered PLUS will be issued under the senior indenture dated March 31, 2009, between HSBC USA Inc., as Issuer, and Wells Fargo Bank, National Association, as trustee.  Such indenture has substantially the same terms as the indenture described in the accompanying prospectus supplement.
Paying Agent	Notwithstanding anything contained in the accompanying prospectus supplement or product supplement to the contrary, HSBC Bank USA, N.A. will act as paying agent with respect to the securities pursuant to a Paying Agent and Securities Registrar Agreement dated June 1, 2009, between HSBC USA Inc. and HSBC Bank USA, N.A.
Calculation agent:	HSBC USA Inc., or one of its affiliates.
Supplemental plan of distribution (conflicts of interest):	Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc., an affiliate of HSBC, will purchase the Buffered PLUS from HSBC for distribution to Morgan Stanley Smith Barney LLC. HSBC Securities (USA) Inc. will act as agent for the Buffered PLUS and will receive a fee of $0.20 per $10 stated principal amount and will pay the entire fee to Morgan Stanley Smith Barney LLC as a fixed sales commission of $0.20 for each Buffered PLUS they sell. In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the Buffered PLUS, but is under no obligation to do so and may discontinue any market-making activities at any time without notice. See “Supplemental Plan of Distribution” on page S-52 in the prospectus supplement. All references to NASD Rule 2720 in the prospectus supplement shall be to FINRA Rule 5121.

How Buffered PLUS Work

Payoff Diagram

The payoff diagram below illustrates the payment at maturity on the Buffered PLUS based on the following terms:

Stated principal amount:	$10 per Buffered PLUS
Leverage factor:	200%
Buffer amount:	10%
Hypothetical maximum payment at maturity:	$12.00 per Buffered PLUS (120% of the stated principal amount).  The actual maximum payment at maturity will be between $11.80 to $12.20 per Buffered PLUS (118% to 122% of the stated principal amount) and will be determined on the pricing date.
Minimum payment at maturity:	$1.00 per Buffered PLUS

Buffered PLUS Payoff Diagram

 

How it works

§ If the final share price is greater than the initial share price, investors would receive the $10 stated principal amount plus 200% of the appreciation of the underlying shares over the term of the Buffered PLUS, subject to the hypothetical maximum payment at maturity of $12.00 per Buffered PLUS. Under the payoff diagram, an investor would realize the hypothetical maximum payment at maturity at a final share price of 110% of the initial share price.

§ If the final share price is less than or equal to the initial share price but has decreased from the initial share price by an amount less than or equal to the buffer amount of 10%, investors would receive the stated principal amount of $10 per Buffered PLUS.

§ If the final share price is less than the initial share price and has decreased from the initial share price by an amount greater than the buffer amount of 10%, investors would receive an amount that is less than the stated principal amount by an amount that is proportionate to the percentage decrease of the underlying shares from the initial share price, plus the buffer amount of 10%. The minimum payment at maturity is $1.00 per Buffered PLUS.

§      For example, if the underlying shares depreciate 35%, investors would lose 25% of their principal and receive only $7.50 per Buffered PLUS at maturity, or 75% of the stated principal amount.

Payment at Maturity

At maturity, investors will receive for each $10 stated principal amount of Buffered PLUS that they hold an amount in cash based upon the closing price of the underlying shares on the valuation date, as determined as follows:

If the final share price is greater than the initial share price:

If the final share price is less than the initial share price and has decreased from the initial share price by an amount greater than the buffer amount of 10%:

Because the share performance factor will be less than 0.9, the payment at maturity will be less than the stated principal amount under this scenario.

Under no circumstances will the payment at maturity be less than $1.00 per Buffered PLUS.

§ Buffered PLUS do not pay interest and may result in a loss. The terms of the Buffered PLUS differ from those of ordinary debt securities in that the Buffered PLUS do not pay interest, and provide a minimum payment at maturity of only 10% of the stated principal amount of the Buffered PLUS, subject to the credit risk of HSBC. If the final share price is less than 90% of the initial share price, you will receive for each Buffered PLUS that you hold a payment at maturity that is less than the stated principal amount of each Buffered PLUS by an amount proportionate to the decline in the price of the underlying shares, plus $1.00 per Buffered PLUS subject to the credit risk of HSBC.

§ The appreciation potential of the Buffered PLUS is limited by the maximum payment at maturity. The appreciation potential of the Buffered PLUS is limited by the maximum payment at maturity of $11.80 to $12.20 per Buffered PLUS (118% to 122% of the stated principal amount). The actual maximum payment at maturity will be determined on the pricing date. Although the leverage factor provides 200% exposure to any increase in the final share price over the initial share price, because the payment at maturity will be limited to 118% to 122% of the stated principal amount for the Buffered PLUS, any increase in the final share price over the initial share price by more than 9% to 11% of the initial share price will not further increase the return on the Buffered PLUS.

§ The market price will be influenced by many unpredictable factors. Several factors will influence the value of the Buffered PLUS in the secondary market and the price at which HSBC Securities (USA) Inc. may be willing to purchase or sell the Buffered PLUS in the secondary market, including: the value, volatility and dividend yield of the underlying shares, 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. The price of the underlying shares may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. You may receive less, and possibly significantly less, than the stated principal amount per Buffered PLUS if you try to sell your Buffered PLUS prior to maturity.

§ There is limited anti-dilution protection. For certain events affecting the underlying shares, such as stock splits or extraordinary dividends, the calculation agent may make adjustments to the final share price which may affect your payment at maturity. However, the calculation agent is not required to make an adjustment for every corporate action which affects the underlying shares. If an event occurs that does not require the calculation agent to adjust the amount

of the shares of the underlying shares, the market price of the Buffered PLUS and the payment at maturity may be materially and adversely affected.

§ An index fund and its share underlying index are different. The performance of an index fund may not exactly replicate the performance of its share underlying index, because the index fund will reflect transaction costs and fees that are not included in the calculation of its share 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 its share underlying index due to the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments contained in the index 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 its share underlying index and in managing cash flows.

§ The underlying shares are subject to management risk. The underlying shares 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 underlying shares, utilizing a ‘‘passive’’ or indexing investment approach, attempt to approximate the investment performance of the share underlying index by investing in a portfolio of securities that generally replicate the share underlying index. Therefore, unless a specific security is removed from the share underlying index, the underlying shares generally would not sell a security because the security’s issuer was in financial trouble. In addition, the underlying shares are subject to the risk that the investment strategy of the underlying shares’ investment advisor may not produce the intended results.

§ Credit risk of HSBC USA Inc. The Buffered PLUS are senior unsecured debt obligations of the issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the Buffered PLUS will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the Buffered PLUS depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the Buffered PLUS and, in the event HSBC were to default on its obligations, you may not receive the amounts owed to you under the terms of the Buffered PLUS.

§ Investing in the Buffered PLUS is not equivalent to investing in the underlying shares or the stocks composing the share underlying index. Investing in the Buffered PLUS is not equivalent to investing in the underlying shares, the share underlying index or the stocks that constitute the share underlying index. Investors in the Buffered PLUS will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying shares or the stocks that constitute the share underlying index.

§ Adjustments to the underlying shares or to the share underlying index could adversely affect the value of the Buffered PLUS.The investment advisor to the iShares^® MSCI Emerging Markets Index Fund, BlackRock Fund Advisors (the “Investment Advisor”), seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the share underlying index. Pursuant to its investment strategy or otherwise, the Investment Advisor may add, delete or substitute the stocks composing the iShares^® MSCI Emerging Markets Index Fund. Any of these actions could adversely affect the price of the underlying shares and, consequently, the value of the Buffered PLUS. Further, MSCI Inc. (“MSCI”) is responsible for calculating and maintaining the share underlying index. MSCI may add, delete or substitute the stocks constituting the share underlying index or make other methodological changes that could change the value of the share underlying index. MSCI may discontinue or suspend calculation or publication of the share underlying index at any time. In these circumstances, the calculation agent will have the sole discretion to substitute a successor index that is comparable to the discontinued share underlying index and will be permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates.

§ Certain built-in costs are likely to adversely affect the value of the Buffered PLUS prior to maturity. The original issue price of the Buffered PLUS includes the agent’s fees and commissions and the estimated cost of HSBC hedging its obligations under the Buffered PLUS. As a result, the price, if any, at which HSBC Securities (USA) Inc. will be willing to purchase Buffered PLUS from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the stated maturity date could result in a substantial loss to you. The Buffered PLUS are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Buffered PLUS to maturity.

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

§ The calculation agent, which is HSBC or one of its affiliates, will make determinations with respect to the Buffered PLUS. As calculation agent, HSBC or one of its affiliates will determine the initial share price, will determine the final share price and will calculate the amount of cash you receive at maturity. Determinations made by HSBC or one of its affiliates in its capacity as calculation agent, including with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or calculation of the final share price in the event of a discontinuance of the share underlying index or a market disruption event, may adversely affect the payout to you at maturity.

§ Hedging and trading activity by our affiliates could potentially adversely affect the value of the Buffered PLUS. One or more of our affiliates expect to carry out hedging activities related to the Buffered PLUS (and possibly to other instruments linked to the underlying shares or the share underlying index), including trading in the underlying shares as well as in other instruments related to the underlying shares. Some of our affiliates also trade the underlying shares and the stocks that constitute the share underlying index and other financial instruments related to the underlying shares and the share 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 potentially increase the initial share price and, therefore, could increase the price at which the underlying shares must close before an investor receives a payment at maturity that exceeds the stated principal amount of the Buffered PLUS. Additionally, such hedging or trading activities during the term of the Buffered PLUS, including on the valuation date, could adversely affect the value of the underlying shares on the valuation date and, accordingly, the amount of cash an investor will receive at maturity.

§ The Buffered PLUS are not insured by any governmental agency of the United States or any other jurisdiction. The Buffered PLUS 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 Buffered PLUS 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 Buffered PLUS.

§ The U.S. federal income tax consequences of an investment in the Buffered PLUS are uncertain. For a discussion of certain of the U.S. federal income tax consequences of your investment in a Buffered PLUS, please see the discussion under “Tax Considerations” herein, the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying product supplement and the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.
