The Securities

The securities are designed for investors who seek Coupon payments that accrue based on the performance of the Reference Asset, while seeking return of principal at maturity if the Reference Return is greater than or equal to the Buffer Level. For each Coupon Period, interest will accrue only on scheduled trading days with respect to which the Official Closing Level of the Reference Asset is greater than or equal to the Coupon Barrier Level.

If the Reference Return is below the Buffer Level, the securities provide 1:1 exposure to the decline in the Reference Asset beyond -30%. If you lose some or a substantial portion of your initial investment, even with any Coupon payments, your yield on an investment in the securities may be negative.

The offering period for the securities is through March 30, 2012

FWP-2

Payoff Example

The table at right shows the hypothetical payout profile of an investment in the securities reflecting the Buffer Level of -30%.

Your total payment on the securities will depend on how frequently the Accrual Provision is satisfied. You will receive your quarterly Coupons on each Coupon Payment Date. If you lose some or a substantial portion of your initial investment, even with any Coupon payments, your yield on an investment in the securities may be negative.

We are using this free writing prospectus to solicit from you an offer to purchase the securities. You may revoke your offer to purchase the securities at any time prior to the time at which we accept your offer by notifying HSBC Securities (USA) Inc. We reserve the right to change the terms of, or reject any offer to purchase, the securities prior to their issuance. In the event of any material changes to the terms of the securities, we will notify you.

PAYMENT AT MATURITY

On the Maturity Date, for each security you hold, we will pay you the Final Settlement Value (plus any Coupon payment), which is an amount in cash, as described below:

If the Reference Return is greater than or equal to the Buffer Level, you will receive $1,000 per $1,000 Principal Amount of securities (zero return).

If the Reference Return is less than the Buffer Level, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 30%)].

Under these circumstances, you will lose 1% of the Principal Amount of your securities for each percentage point that the Reference Return is below the Buffer Level. For example, if the Reference Return is -40%, you will suffer a 10% loss and receive 90% of the Principal Amount. If the Reference Return is less than the Buffer Level, you may lose up to 70% of your investment.

COUPON

On each Coupon Payment Date, for each $1,000 Principal Amount of securities, you will be paid an amount equal to the product of (a) $1,000 multiplied by (b) the Coupon Rate divided by four. For information regarding the record dates applicable to the Coupons paid on the securities, please see the section entitled “Description of Notes – Interest and Principal Payments – Recipients of Interest Payments” on page S-11 in the accompanying prospectus supplement.

With respect to each Coupon Period, the “Coupon Rate” is a rate, per annum, calculated as follows:

5.60% ×	Variable Days	, where
	Scheduled Trading Days

FWP-6

“Variable Days” is the actual number of scheduled trading days during such Coupon Period on which the Accrual Provision is satisfied, and “Scheduled Trading Days” means the actual number of scheduled trading days in the Coupon Period, subject to adjustment as described under “Observation Periods” in the accompanying Equity Index Underlying Supplement.

Calculation Agent

We or one of our affiliates will act as calculation agent with respect to the securities.

Reference Sponsor

Standard and Poor’s Financial Services LLC, a subsidiary of The McGraw-Hill Companies, Inc., is the reference sponsor.

INVESTOR SUITABILITY

The securities may be suitable for you if:

}

You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is less than the Buffer Level of -30%.

}

You are willing to invest in the securities based on the fact that your maximum potential return is the Coupon being offered with respect to your securities, which may equal 0.00% if the Accrual Provision is never satisfied during a Coupon Period.

}

You are willing to forgo dividends or other distributions paid to holders of stocks comprising the Reference Asset.

}

You do not seek an investment for which there is an active secondary market.

}

You are unwilling to invest in the securities based on the fact that your maximum potential return is the Coupon being offered with respect to your securities, which may equal 0.00% if the Accrual Provision is never satisfied during a Coupon Period.

}

You seek an investment that provides full return of principal.

}

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 the dividends or other distributions paid on any stocks comprising the Reference Asset.

}

You seek an investment for which there will be an active secondary market.

FWP-7

RISK FACTORS

We urge you to read the section “Risk Factors” on page S-3 in the accompanying prospectus supplement and on page S-1 of the Equity Index Underlying Supplement. Investing in the securities is not equivalent to investing directly in any of the stocks comprising the Reference Asset. You should understand the risks of investing in the securities and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the securities in light of your particular financial circumstances and the information set forth in this free writing prospectus and the accompanying underlying supplement, prospectus supplement and prospectus.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and underlying supplement including the explanation of risks relating to the securities described in the following sections:

}

“— Risks Relating to All Note Issuances” in the prospectus supplement; and

}

“— General risks related to Indices” in the Equity Index Underlying Supplement.

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

Your investment in the securities may result in a loss.

You will be exposed to any decline in the Final Level from the Initial Level beyond the Buffer Level of -30%. Accordingly, if the Reference Return is less than -30%, your Payment at Maturity will be less than the Principal Amount of your securities. You may lose up to 70% of your investment at maturity if the Reference Return is negative.

You will not participate in any appreciation in the level of the Reference Asset.

The securities will not pay more than the Principal Amount, plus any unpaid Coupon payment, at maturity. Even if the Reference Return is greater than zero, you will not participate in the appreciation of the Reference Asset. Assuming the securities are held to maturity, the maximum amount payable with respect to the securities will not exceed the sum of the Principal Amount plus any Coupons. Under no circumstances, regardless of the extent to which the level of the Reference Asset appreciates, will your return exceed the total amount of the Coupons. In some cases, you may earn significantly less by investing in the securities than you would have earned by investing in an instrument directly linked to the performance of the Reference Asset.

Credit risk of HSBC USA Inc.

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 Coupons and any return 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 the amounts owed to you under the terms of the securities.

The securities are not ordinary debt securities and the Coupon Rate is not fixed but is variable.

The Coupon Rate paid by us on the securities for each Coupon Period is not fixed but will vary depending on whether the Accrual Provision is satisfied, and whether such Accrual Provision is satisfied will depend on the daily fluctuations of the Official Closing Level of the Reference Asset. Consequently, the return on the securities may be less than those otherwise payable on debt issued by us with similar maturities and may be zero. Although the variable Coupon Rate on the securities is determined, in part, by reference to the Official Closing Level, the Coupon Rate is linked to 5.60% per annum. You should consider, among other things, the overall annual percentage rate of interest to maturity as compared to other equivalent investment alternatives.

Changes that affect the Reference Asset will affect the market value of the securities and the amount you will receive at maturity.

The policies of the reference sponsor concerning additions, deletions and substitutions of the constituents comprising the Reference Asset and the manner in which the reference sponsor takes account of certain changes affecting those constituents included in the Reference Asset may affect the level of the Reference Asset. The policies of the reference sponsor with respect to the calculation of the Reference Asset could also affect the level of the Reference Asset. The reference sponsor may discontinue or suspend calculation or dissemination of the Reference Asset. Any such actions could affect the 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.

FWP-8

Certain built-in costs are likely to adversely affect the value of the securities prior to maturity.

While the Payment at Maturity described in this free writing prospectus is based on the full Principal Amount of your securities, the original issue price of the securities includes the placement agent’s commission and the estimated cost of HSBC hedging its obligations under the securities. As a result, the price, if any, at which HSBC Securities (USA) Inc. will be willing to purchase securities from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the Maturity Date could result in a substantial loss to you. The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity.

The securities lack liquidity.

The securities will not be listed on any securities exchange. HSBC Securities (USA) Inc. is not required to offer to purchase the securities in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. 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 HSBC Securities (USA) Inc. is willing to buy the securities.

Potential conflicts.

HSBC and its affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities. We will not have any obligation to consider your interests as a holder of the securities in taking any action that might affect the value of your securities.

Uncertain tax treatment.

For a discussion of the U.S. federal income tax consequences of your investment in a security, please see the discussion under “U.S. Federal Income Tax Considerations” herein and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

ILLUSTRATIVE EXAMPLES

The following table 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 Reference Asset relative to its Initial Level. We cannot predict the Final Level of the Reference Asset or the level of the Reference Asset on any scheduled trading day. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events, and the hypothetical Initial Level used in the table and examples below is not the actual Initial Level. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset or the return on your securities. With respect to the securities, the Final Settlement Value plus any Coupons may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including those issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Final Settlement Value on a $1,000 investment in securities for a hypothetical range of performance for the Reference Return from -100% to +100% (excluding any Coupons received). The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Security” as used below is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 Principal Amount of securities to $1,000. The potential returns described here assume that your securities are held to maturity. You should consider carefully whether the securities are suitable to your investment goals. The following table and examples assume the following:

}	Principal Amount:	$1,000

}	Hypothetical Initial Level:	1,400.00

}	Buffer Level:	-30%

}	Coupon Barrier Level:	70% of the Initial Level

}	Scheduled Trading Days in final Coupon Period: 61

The actual Initial Level and Coupon Barrier Level will be determined on the Pricing Date.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Final Settlement Value	Hypothetical Return on the Security

The following examples indicate how the Final Settlement Value would be calculated with respect to a hypothetical $1,000 investment in the securities.

Example 1: The level of the Reference Asset increases from the Initial Level of 1,400.00 to a Final Level of 1,540.00. The Official Closing Level of the Reference Asset is greater than or equal to the Coupon Barrier Level on 40 scheduled trading days during the final Coupon Period.


Reference Return:	10.00%
Coupon Rate:	3.67% per annum
Final Settlement Value:	$1,000.00
Payment at Maturity:	$1,009.18

Because the Reference Return is positive, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount of securities (a zero return).

Further, because the Accrual Provision is satisfied for 40 scheduled trading days, the Coupon Rate for the final Coupon Period is 3.67% per annum, calculated as follows:

5.60% × ( 40 / 61 ) = 3.67% per annum

Therefore, with the final Coupon payment of $9.18, the total Payment at Maturity is $1,009.18.

Example 1 shows that you will receive the return of your principal investment plus the final Coupon payment when the Reference Asset appreciates.

Example 2: The level of the Reference Asset decreases from the Initial Level of 1,400.00 to a Final Level of 1,330.00. The Official Closing Level of the Reference Asset is greater than or equal to the Coupon Barrier Level on each scheduled trading day during the final Coupon Period.


Reference Return:	-5.00%
Coupon Rate:	5.60% per annum
Final Settlement Value:	$1,000.00
Payment at Maturity:	$1,014.00

Because the Reference Return is less than zero but greater than the Buffer Level of -30%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount of securities (a zero return).

Further, because the Accrual Provision is satisfied for 61 scheduled trading days, the Coupon Rate for the final Coupon Period is 5.60% per annum, calculated as follows:

5.60% × ( 61 / 61 ) = 5.60% per annum

Therefore, with the final Coupon payment of $14.00, the total Payment at Maturity is $1,014.00.

Example 2 shows that you will receive the return of your principal investment plus the final Coupon payment when the Reference Asset declines but is greater than or equal to the Buffer Level of -30%.

Example 3: The level of the Reference Asset decreases from the Initial Level of 1,400.00 to a Final Level of 840.00. The Official Closing Level of the Reference Asset is less than the Coupon Barrier Level on each scheduled trading day during the final Coupon Period.


Reference Return:	-40.00%
Coupon Rate:	0.00% per annum
Final Settlement Value:	$900.00
Payment at Maturity:	$900.00

Because the Reference Return is less than the Buffer Level of -30%, the Final Settlement Value would be $900.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 30%)]

= $1,000 + [$1,000 × (-40.00% + 30%)]

= $900.00

Because the Accrual Provision is never satisfied during the final Coupon Period, the Coupon Rate for the final Coupon Period is 0.00% per annum, calculated as follows:

5.60% × ( 0 / 61 ) = 0.00% per annum

Example 3 shows that you are exposed on a 1-to-1 basis to declines in the level of the Reference Asset beyond the Buffer Level of -30%. YOU MAY LOSE UP TO 70% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

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

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the securities. Under one reasonable approach, the securities should be treated as income-bearing pre-paid derivative contracts with respect to the Reference Asset. 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 intends to treat any gain or loss upon maturity or an earlier sale or exchange as capital gain or loss in an amount equal to the difference between the amount you receive at such time (other than with respect to a coupon) and your tax basis in the security. Any such gain or loss will be long-term capital gain or loss if you have held the security for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a security generally will equal your cost of the security. In addition, the tax treatment of the coupon is unclear. Although the tax treatment of the coupon is unclear, HSBC intends to treat any coupon paid by HSBC, including on the Maturity Date, as ordinary income includible in income by you at the time it accrues or is received in accordance with your normal method of accounting for U.S. federal income tax purposes. See “U.S. Federal Income Tax Considerations — Certain Equity-Linked Notes — Certain Notes Treated as Forward Contracts or Executory Contracts” in the prospectus supplement for the U.S. federal income tax considerations applicable to securities that are treated as income-bearing pre-paid derivative contracts.

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

In addition, if you are a non-U.S. Holder (as defined in the prospectus supplement), because the tax treatment of the coupon is unclear, HSBC intends to withhold an amount equal to 30% of any coupon payable to you, subject to reduction or elimination by applicable treaty, unless income from such coupon is effectively connected with your conduct of a trade or business within the United States.

In Notice 2008-2, the Internal Revenue Service (“IRS”) and the Treasury Department requested comments as to whether the purchaser of an exchange traded note or pre-paid forward contract (which may include the securities) should be required to accrue income during its term under a mark-to-market, accrual or other methodology, whether income and gain on such a note or contract should be ordinary or capital, and whether foreign holders should be subject to withholding tax on any deemed income accrual. Accordingly, it is possible that regulations or other guidance could provide that a U.S. holder (as defined in the prospectus supplement) of a security is required to accrue income in respect of the 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 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.
