The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to a single Reference Asset. Although the offering of securities relates to the Reference Asset identified on the cover page, 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.

INVESTOR SUITABILITY

The securities may be suitable for you if:

The securities may not be suitable for you if:

} You believe that the Official Closing Level of the Reference Asset will not decline by more than 35%, as compared to the Initial Level, on the Final Valuation Date. } 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 below zero if the Reference Return is less than the Barrier Level. } You are willing to accept the risk and return profile of the securities versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating. } 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.

PS-5

RISK FACTORS

We urge you to read the section “Risk Factors” on page S-3 in the accompanying prospectus supplement, on page PS-4 of the accompanying product supplement and on page US3-1 of underlying supplement no. 3. 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 underlying supplement, product supplement, prospectus supplement and prospectus.

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

} “—Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset” in the prospectus supplement;

} “—Securities Prices Generally are Subject to Political, Economic, Financial and Social Factors that Apply to the Markets in which they Trade and, to a Lesser Extent, Foreign Markets” in underlying supplement no. 3; and

} “—The Notes will Not be Adjusted for Changes in Exchange Rates” in underlying supplement no. 3.

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 level of the Reference Asset if the Reference Return is less than the Barrier Level. Accordingly, if the Reference Return is less than -35%, your Payment at Maturity will be less than the Principal Amount of your securities. You may lose up to 100% of your investment at maturity if the Reference Return is less than the Barrier Level.

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.

Please read and pay particular attention to the section “Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset” in the accompanying prospectus supplement.

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-6

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, 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.

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. 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 of the Reference Asset. 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:	2,500.00
}	Minimum	18.15%
	Upside Return:
}	Barrier Level:	-35%

The actual Initial Level was determined on the Pricing Date.

PS-8

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 2,500.00 to a Final Level of 2,625.00.

Reference Return:	5.00%
Final Settlement Value:	$1,181.50

Because the Reference Return is greater than the Barrier Level and less than the Minimum Upside Return, the investor receives the Minimum Upside Return and the Final Settlement Value would be $1,181.50 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Minimum Upside Return)

= $1,000 + ($1,000 × 18.15%)

= $1,181.50

Example 1 shows that you will benefit from the Minimum Upside Return at maturity when the Reference Return is greater than or equal to the Barrier Level but less than the Minimum Upside Return.

Example 2: The level of the Reference Asset decreases from the Initial Level of 2,500.00 to a Final Level of 2,375.00.

Reference Return:	-5.00%
Final Settlement Value:	$1,181.50

Although the Reference Return is negative, the Reference Return is greater than the Barrier Level and, therefore, the investor receives the Minimum Upside Return. The Final Settlement Value would be $1,181.50 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Minimum Upside Return)

= $1,000 + ($1,000 × 18.15%)

= $1,181.50

Example 2 shows that you will also benefit from the Minimum Upside Return at maturity when the Reference Return is less than zero but greater than or equal to the Barrier Level.

Example 3: The level of the Reference Asset increases from the Initial Level of 2,500.00 to a Final Level of 4,000.00.

Reference Return:	60.00%
Final Settlement Value:	$1,600.00

Because the Reference Return is greater than both the Barrier Level and the Minimum Upside Return, the investor receives the Reference Return and the Final Settlement Value would be $1,600.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Reference Return)

= $1,000 + ($1,000 × 60.00%)

= $1,600.00

Example 3 shows that you will receive the return of your principal investment plus a return equal to the Reference Return at maturity when the Reference Return is greater than the Barrier Level and greater than the Minimum Upside Return.

PS-9

Example 4: The level of the Reference Asset decreases from the Initial Level of 2,500.00 to a Final Level of 1,500.00.

Reference Return:	-40.00%
Final Settlement Value:	$600.00

Because the Reference Return is less than the Barrier Level, the Final Settlement Value would be $600.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Reference Return)

= $1,000 + ($1,000 × -40.00%)

= $600.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the level of the Reference Asset if the Reference Return is less than the Barrier Level. IF THE REFERENCE RETURN IS LESS THAN THE BARRIER LEVEL, YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the securities. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the securities from HSBC for distribution to other registered broker-dealers or will offer the securities directly to investors. HSBC Securities (USA) Inc. will offer the securities at the offering price set forth on the cover page of this pricing supplement and will receive underwriting discounts and commissions of up to 2.00%, or $20.00, per $1,000 Principal Amount of securities. HSBC Securities (USA) Inc. may allow selling concessions on sales of such securities by other brokers or dealers of up to 2.00%, or $20.00.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use this pricing supplement in market-making transactions after the initial sale of the securities, 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.

We expect that delivery of the securities will be made against payment for the securities on or about the Original Issue Date set forth on page PS-2 of this document, which is expected to be the fifth business day following the Trade Date of the securities.  Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise.  Accordingly, purchasers who wish to trade securities on the Trade Date and the following business day thereafter will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

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. 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 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.

On March 18, 2010, the Hiring Incentives to Restore Employment Act (the “HIRE Act”) was signed into law. Under certain circumstances, the HIRE Act will impose a withholding tax of 30% on payments of U.S. source income on, and the gross proceeds from a disposition of, securities made to certain foreign entities unless various information reporting requirements are satisfied. These rules generally would apply to payments made after December 31, 2012. However, under the HIRE Act, the withholding and reporting requirements generally will not apply to payments made on, or gross proceeds from a disposition of, securities outstanding as of March 18, 2012 (the “Grandfather Date”).

Despite the December 31, 2012 date set forth in the HIRE Act, the Internal Revenue Service (the “IRS”) has issued preliminary guidance indicating that the withholding tax on U.S. source income will not be imposed with respect to payments made prior to January 1, 2014 and that the withholding tax on gross proceeds from a disposition of securities will not be imposed with respect to payments made prior to January 1, 2015. In addition, the IRS has released proposed regulations that would extend the Grandfather Date to January 1, 2013. These proposed regulations would be effective once finalized. Prospective investors should consult their tax advisors regarding the HIRE Act.
