GENERAL

This pricing supplement relates to an offering of securities linked to the Reference Asset. The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to the Reference Asset. Although the offering of securities relates to the Reference Asset, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the Reference Asset or any component security included in the Reference Asset or as to the suitability of an investment in the securities.

You should read this document together with the prospectus dated March 22, 2012, the prospectus supplement dated March 22, 2012 and the Equity Index Underlying Supplement dated March 22, 2012. If the terms of the securities offered hereby are inconsistent with those described in the accompanying Equity Index Underlying Supplement, prospectus supplement or prospectus, the terms described in this pricing supplement shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-5 of this pricing supplement, page S-3 of the prospectus supplement and page S-1 of Equity Index Underlying Supplement, as the securities involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, prospectus supplement and Equity Index Underlying Supplement) with the SEC for the offering to which this pricing supplement relates. Before you invest, you should read the prospectus, prospectus supplement and Equity Index Underlying Supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering. You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov. Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and Equity Index Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

PAYMENT AT MATURITY

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

If the Reference Return is greater than zero, 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 × Upside Participation Rate).

If the Reference Return is less than or equal to zero but greater than or equal to the Buffer Level, you will receive a cash payment on the Maturity Date of $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 + 20%)].

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 -30%, you will suffer a 10% loss and receive 90% of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the Reference Return is less than the Buffer Level, you may lose up to 80% of your investment.

PS-3

INVESTOR SUITABILITY

The securities may be suitable for you if:

The securities may not be suitable for you if:

} You seek an investment with a return linked to the potential positive performance of the Reference Asset and you believe the level of the Reference Asset will increase over the term of the securities. } 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 -20%. } You are willing to forgo dividends or other distributions paid to holders of stocks comprising the Reference Asset. } You do not seek current income from your investment. } You do not seek an investment for which there is an active secondary market. } You are willing to hold the securities to maturity. } You are comfortable with the creditworthiness of HSBC, as Issuer of the securities.

} You believe the Reference Return will be negative or that the Reference Return will not be sufficiently positive to provide you with your desired return. } You are unwilling 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 below the Buffer Level of -20%. } 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 current income from your investment. } You seek an investment for which there will be an active secondary market. } You are unable or unwilling to hold the securities to maturity. } You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the securities.

PS-4

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-3 in the accompanying prospectus supplement and on page S-1 of the accompanying 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 pricing supplement and the accompanying Equity Index Underlying Supplement, prospectus supplement and prospectus.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and Equity Index 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;

} “— General risks related to Indices” in the Equity Index Underlying Supplement; and

} “— If the Reference Asset is or includes the S&P 500 Low Volatility Index or otherwise includes an Index that tracks a low volatility index” 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 the decline in the Final Level from the Initial Level beyond the Buffer Level of -20%. Accordingly, if the Reference Return is less than -20%, your Payment at Maturity will be less than the Principal Amount of your securities. You may lose up to 80% of your investment at maturity if the Reference Return is negative.

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 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 will not bear interest.

As a holder of the securities, you will not receive interest payments.

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.

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 pricing supplement 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.

PS-5

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.

PS-6

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 actual Final Level. 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 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 Payment at Maturity on a $1,000 investment in the securities for a hypothetical range of performance for the Reference Return from -100% to +100%. 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:	4,000
}	Upside Participation Rate:	110%
}	Buffer Level:	-20%

The actual Initial Level was determined on the Pricing Date.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Security
8,000	100.00%	$2,100	110.00%

PS-7

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 4,000 to a Final Level of 5,600.

Reference Return:	40%
Final Settlement Value:	$1,440

Because the Reference Return is positive, the Final Settlement Value would be $1,440 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Reference Return × Upside Participation Rate)

= $1,000 + ($1,000 × 40.00% × 110%)

= $1,440.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by the Upside Participation Rate when the Reference Asset appreciates.

Example 2: The level of the Reference Asset decreases from the Initial Level of 4,000 to a Final Level of 3,800.

Reference Return:	-5.00%
Final Settlement Value:	$1,000.00

Because the Reference Return is less than zero but greater than the Buffer Level of -20%, the Final Settlement Value would be $1,000 per $1,000 Principal Amount of securities (a zero return).

Example 3: The level of the Reference Asset decreases from the Initial Level of 4,000 to a Final Level of 2,400.

Reference Return:	-40%
Final Settlement Value:	$800

Because the Reference Return is less than the Buffer Level of -20%, the Final Settlement Value would be $800.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 20%)]

= $1,000 + [$1,000 × (-40.00% + 20%)]

= $800.00

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 -20%. YOU MAY LOSE UP TO 80% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

PS-8

THE S&P 500 LOW VOLATILITY INDEX (“SP5LVI”)

Description of the Reference Asset

The SP5LVI measures the performance of the 100 least volatile stocks over the previous year in the S&P 500^® Index. It is designed to serve as a benchmark for low volatility strategies in the U.S. stock market.

As of the May 2012 rebalancing, the sector weightings in the Index were as follows: Consumer Discretionary: 8.10%, Consumer Staples: 29.40%, Energy: 1.70%, Financials: 0.80%, Healthcare: 12.40%, Industrials: 4.40%, Information Technology: 4.30%, Materials: 2.40%, Telecommunication Services: 4.90% and Utilities: 31.40%.

For more information about the SP5LVI, see “The S&P 500 Low Volatility Index” on page S-18 of the accompanying Equity Index Underlying Supplement.

Hypothetical and ActualHistorical Performance of the SP5LVI

The following graph sets forth the hypothetical back-tested performance of the SP5LVI from May 23, 2007 through April 19, 2011 and the historical performance of the SP5LVI from April 20, 2011 to May 23, 2012. The SP5LVI has only been calculated since April 20, 2011. The hypothetical back-tested performance of the SP5LVI set forth in the following graph was calculated using the selection criteria and methodology employed to calculate the SP5LVI since its inception on April 20, 2011. Accordingly, while the hypothetical graph set forth below is based on the selection criteria and methodology described herein, the SP5LVI was not actually calculated and published prior to April 20, 2011. The graph below also reflects the actual closing levels from April 20, 2011 to May 23, 2012 that we obtained from Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from Bloomberg Professional^® service. The closing level for the SP5LVI on May 23, 2012 was 4,244.70. The hypothetical and actual performance is not necessarily an indication of future results.

The hypothetical and actual historical levels of the SP5LVI should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the SP5LVI on the Final Valuation Date.

The tables below are a comparison of the 1997 through 2011 annual returns and the 1,3,5,10,15 and 20 year annualized returns and standard deviations for the S&P 500 Low Volatility Index and the S&P 500^® Index. The SP5LVI has only been calculated since April 20, 2011. Accordingly, while the hypothetical tables set forth below are based on the selection criteria and methodology described herein, the SP5LVI was not actually calculated and published prior to April 20, 2011. The hypothetical and actual historical performance is not necessarily an indication of future results.

PS-10

U.S. FEDERAL INCOME TAX CONSIDERATIONS

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 approach, a security should be treated as a pre-paid forward or other executory contract with respect to the Reference Asset. We intend to treat the securities consistent with this approach. 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 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 a security as a pre-paid forward or other executory contract with respect to the Reference Asset. Pursuant to this approach, we do not intend to report any income or gain with respect to the securities prior to their 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 security for more than one year at such time for U.S. federal income tax purposes.

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” in the accompanying prospectus supplement.

This opinion is given as of the date hereof and is limited to the Federal laws of the United States, the laws of the State of New York and the Maryland General Corporation Law as in effect on the date hereof. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the Senior Indenture and the genuineness of signatures and certain factual matters, all as stated in the letter of such counsel dated March 22, 2012, which has been filed as Exhibit 5.3 to the Issuer’s registration statement on Form S-3 filed with the Securities and Exchange Commission on March 22, 2012.
