This free writing prospectus relates to the offering of Securities linked to the Index identified on the cover page. The Index described in this free writing prospectus is a reference asset as defined in underlying supplement no. 1 and the prospectus supplement, and the Securities being offered hereby are “notes” for purposes of underlying supplement no. 1 and the prospectus supplement. As a purchaser of a Security, you will acquire an investment instrument linked to the Index.

Investor Suitability
The Securities may be suitable for you if: ¨ You believe the Index will maintain its value or increase over the term of the Securities, but that any increase is unlikely to exceed the Maximum Gain. ¨ You are willing to invest in the Securities based on the Contingent Return of 9.00% and the range indicated for the Maximum Gain of 20.00% to 25.00% (to be determined on the trade date). ¨ You are willing to hold the Securities to maturity, a term of 18 months. ¨ You are willing to expose your principal to the full downside performance of the Index if the Index Ending Level is below the Trigger Level on the final valuation date. ¨ You are willing to forgo dividends or other distributions paid on the stocks included in the Index in exchange for (i) returns subject to the Maximum Gain if the Index appreciates above the Contingent Return and (ii) the Contingent Return if the Index depreciates but is not below the Trigger Level on the final valuation date. ¨ You do not seek current income from this investment. ¨ You do not seek an investment for which there is an active secondary market. ¨ You are comfortable with the creditworthiness of HSBC, as issuer of the Securities.		The Securities may not be suitable for you if: ¨ You believe the increase in the level of the Index will be more than moderate over the term of the Securities – meaning that such an increase is likely to exceed the Maximum Gain indicated herein at maturity. ¨ You believe the level of the Index will decrease over the term of the Securities beyond the Trigger Level or that any increase in the level of the Index will not be sufficient to provide you with your desired return. ¨ You are not willing to make an investment that is exposed to the full downside performance of the Index. ¨ You are unable or unwilling to hold the Securities to maturity. ¨ You seek an investment that is 100% principal protected. ¨ 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 prefer to receive dividends or other distributions paid on stocks included in the Index. ¨ You seek current income from this investment. ¨ 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.

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” beginning on page 6 of this free writing prospectus and the more detailed “Risk Factors” beginning on page US1-1 of the underlying supplement no. 1 and beginning on page S-3 of the accompanying prospectus supplement.

Principal Amount	$10 per Security
Term	18 months
Index	S&P 500® Index
Payment at Maturity (per $10 Security)2	You will receive a cash Payment at Maturity linked to the performance of the Index during the term of the Securities. If the Index Return is greater than the Contingent Return, you will receive the sum of (a) the Principal Amount plus (b) the Index Return, up to the Maximum Gain, calculated as follows, the lesser of: (A) $10 + [$10 × the Index Return] and (B) $10 + [$10 × the Maximum Gain]. If the Index Return is equal to or less than the Contingent Return and the Index Ending Level is at or above the Trigger Level , you will receive the sum of (a) the Principal Amount plus (b) the Contingent Return, calculated as follows: $10 + [$10 × the Contingent Return]. If the Index Ending Level is below the Trigger Level, you will receive the sum of (a) the Principal Amount plus (b) the product of (i) the Principal Amount multiplied by (ii) the Index Return, calculated as follows: $10 + [$10 × Index Return]. In this case the contingent return is lost, and you will lose some or all of your Principal Amount.
Trigger Level	80% of the Index Starting Level.
Contingent Return	9.00%
Maximum Gain	Between 20.00% and 25.00%. The actual Maximum Gain will be determined on the trade date.

Calculation Agent	HSBC USA Inc., or one of its affiliates.
Trustee	Notwithstanding anything contained in the accompanying prospectus supplement to the contrary, the Securities 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	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.

Determining Payment at Maturity

For each $10 invested, you will receive an amount equal to the sum of (a) the Principal Amount plus (b) the product of (i) the Principal Amount multiplied by (ii) the Index Return. Accordingly, for each $10 invested, your Payment at Maturity will be calculated as follows:

$10 + [$10 × Index Return]

If the Index Ending Level is below the Trigger Level on the final valuation date, the contingent return is lost and your Principal Amount will be fully exposed to any decline in the Index. As a result, you will lose some or all of your Principal Amount at maturity.

1 HSBC USA Inc. is rated A1 by Moody’s, AA- by Standard & Poor’s and AA by Fitch Ratings. A credit rating reflects the creditworthiness of HSBC USA Inc. and is not a recommendation to buy, sell or hold Securities, and it may be subject to revision or withdrawal at any time by the assigning rating organization. The Securities themselves have not been independently rated. Each rating should be evaluated independently of any other rating. However, because the return on the Securities is dependent upon factors in addition to HSBC’s ability to pay its obligations under the Securities, such as the Index Ending Level, an improvement in HSBC’s credit ratings, financial condition or results of operations is not expected to have a positive effect on the trading value of the Securities.

2 Payment at Maturity and any principal protection is provided by HSBC USA Inc., and therefore, is dependent on the ability of HSBC USA Inc. to satisfy its obligations when come due.

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 entity included in the Index. 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 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 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, 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.

HSBC will not attempt to ascertain whether any of the entities whose stock is included in the Index would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the Index 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 entities whose stock is included in the Index and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Index is or becomes a PFIC or a USRPHC.

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 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 under “Certain U.S. Federal Income Tax Considerations” in the prospectus supplement) 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.

Scenario Analysis and Examples at Maturity

The below scenario analysis and examples are hypothetical and provided for illustrative purposes only. They do not purport to be representative of every possible scenario concerning increases or decreases in the Index Ending Level relative to the Index Starting Level. The Index Ending Level on the final valuation date cannot be predicted. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Index. 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:	18 months

Hypothetical Index Starting Level:	1,100.00

Hypothetical Trigger Level:	880.00 (80.00% of the Index Starting Level)

Contingent Return:	9.00%

Hypothetical Maximum Gain:	22.50% (the midpoint of the expected range of between 20.00% and 25.00%)

*The actual Index Starting Level, Trigger Level and Maximum Gain for the Securities will be determined on the trade date.

Example 1— The level of the Index increases from an Index Starting Level of 1,100.00 to an Index Ending Level of 1,265.00. The Index Return is greater than zero and expressed as a formula:

Index Return = (1,265.00 -1,100.00)/ 1,100.00 = 15.00%

Because the Index Return is greater than the Contingent Return, the Payment at Maturity for each $10 Principal Amount of Securities is calculated as follows,

the lesser of:

(A) $10.00 + [$10.00 × Index Return], and

(B) $10.00 + [$10.00 × the Maximum Gain]

= the lesser of (A) $10.00 + [$10.00 × 15.00%] and (B) $10.00 + [$10.00 × 22.50%]

=$10.00 + [$10.00 × 15.00%]

=$10.00 + $1.50

=$11.50

Example 2— The level of the Index increases from an Index Starting Level of 1,100.00 to an Index Ending Level of 1,595.00. The Index Return is greater than zero and expressed as a formula:

Index Return = (1,595.00 -1,100.00)/ 1,100.00 = 45.00%

Because the Index Return is greater than the Contingent Return, the Payment at Maturity for each $10 Principal Amount of Securities is calculated as follows,

the lesser of:

(A) $10.00 + [$10.00 × Index Return], and

(B) $10.00 + [$10.00 × the Maximum Gain]

= the lesser of (A) $10.00 + [$10.00 × 45.00%] and (B) $10.00 + [$10.00 × 22.50%]

=$10.00 + [$10.00 × 22.50%]

=$10.00 + $2.25

=$12.25

Example 3— The level of the Index increases from an Index Starting Level of 1,100.00 to an Index Ending Level of 1,155.00. The Index Return is greater than zero and expressed as the formula:

Index Return = (1,155.00 -1,100.00)/1,100.00 = 5.00%

Because the Index Return is less than the Contingent Return, and the Index Ending Level is at or above the Trigger Level, the Payment at Maturity for each $10 Principal Amount of Securities is calculated as follows:

$10.00 + [$10.00 × the Contingent Return]

=$10.00 + [$10.00 × 9.00%]

=$10.00 + $0.90

=$10.90

Example 4— The level of the Index decreases from an Index Starting Level of 1,100.00 to an Index Ending Level of 990.00. The Index Return is less than zero and expressed as the formula:

Index Return = (990.00 -1,100.00)/1,100.00 = -10.00%

$10.00 + [$10.00 × the Contingent Return]

=$10.00 + [$10.00 × 9.00%]

=$10.00 + $0.90

=$10.90

Example 5— The level of the Index decreases from an Index Starting Level of 1,100.00 to an Index Ending Level of 440.00. The Index Return is less than zero and is expressed as a formula:

Index Return = (440.00 -1,100.00)/1,100.00 = -60.00%

Because the Index Ending Level is below the Trigger Level, the investor loses the contingent principal protection and is fully exposed to any decline in the Index Ending Level relative to the Index Starting Level. The Payment at Maturity for each $10 Principal Amount of Securities is calculated as follows:

$10.00 + [$10.00 × Index Return]

=$10.00 + [$10.00 × -60.00%]

=$10.00 + [-$6.00]

=$4.00

If the Index Ending Level is below the Trigger Level on the final valuation date, investors are fully exposed to any decline of the Index and will lose some or all of their principal at maturity.

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. 1 and the accompanying prospectus supplement. You are also urged to consult your investment, legal, tax, accounting and other advisers before you invest in the Securities.

You May Lose Up to 100% of Your Initial Investment – The Securities do not guarantee any return of principal at maturity. We will not pay you 100% of your Principal Amount at maturity if the Index Ending Level is below the Trigger Level. In that case, we will deliver to you at maturity an amount in cash equal to your Principal Amount reduced by the Index Return. This amount will be less than 100% of the Principal Amount of your Securities and you will be exposed to the full downside risk of the Index. Accordingly, you may lose some or all of your initial investment if the Index Ending Level is below the Trigger Level.

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 Index has appreciated since the trade date.

The Securities are Subject to the Credit Risk of the 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 principal protection 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 the contingent principal protection or any other amounts owed to you under the terms of the Securities.

Maximum Gain – You will not participate in any appreciation in the level of the Index beyond the Maximum Gain that will be between 20.00% and 25.00% (to be determined on the trade date). YOU WILL NOT RECEIVE A RETURN ON THE SECURITIES GREATER THAN THE MAXIMUM GAIN.

The Contingent Return Applies Only if You Hold the Securities to Maturity – You should be willing to hold the Securities to maturity. If you sell your Securities prior to maturity in the secondary market, you may have to sell them at a discount and your initial investment will not be protected.

No Periodic Interest or Dividend Payments or Voting Rights – As a holder of the Securities, you will not receive periodic interest payments, and you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of stocks comprising the Index would have.

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

Potential HSBC Impact on Price – Trading or transactions by HSBC or its affiliates in the stocks comprising the Index or in futures, options, exchange-traded funds or other derivative products on stocks comprising the Index or the Index itself, may adversely affect the market value of the stocks comprising the Index and the level of the Index, and, therefore, the market value of your Securities.

Lack of Liquidity – The Securities will not be listed on any securities exchange or quotation system. One of HSBC’s affiliates 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 and 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 HSBC’s affiliates is willing to buy the Securities, which will exclude any fees or commissions you paid when you purchased the Securities.

Potential Conflict of Interest – HSBC or its affiliates may engage in business with the issuers of the stocks comprising the 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 Index Ending Level. The Calculation Agent can postpone the determination of the Index 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 stocks included in the Index or the level of 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.

	¨	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 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. 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.

		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 under “Certain U.S. Federal Income Tax Considerations” in the prospectus supplement) 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.

The S&P 500® Index

Description of the Index

The Index is a capitalization weighted index and is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the Index is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. Ten main groups of companies comprise the Index with the approximate percentage of the market capitalization of the Index included in each group as of August 26, 2010 indicated in parentheses: Information Technology (18.44%), Financials (15.81%), Consumer Staples (11.82%), Health Care (11.77%), Energy (10.80%), Industrials (10.37%), Consumer Discretionary (10.31%), Utilities (3.88%), Materials (3.56%) and Telecommunication Services (3.24%).

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 Index Ending Level. If a market disruption event exists with respect to the Index on that scheduled trading day, then the accelerated final valuation date for the Index 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 then be the fourth business day following the postponed accelerated final valuation 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.
