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

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 prospectus supplement, prospectus, or Equity Index Underlying Supplement, 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 the 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.

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, equal to the lesser of:

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

(b) $1,000 + ($1,000 × Maximum Cap).

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

If the Reference Return is less than the Buffer Value, 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 + 10%)).

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 Value. For example, if the Reference Return is -30%, you will suffer a 20% loss and receive 80% 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 Value, you will lose up to 90% of your investment.

Interest

The securities will not pay interest.

Calculation Agent

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

Reference Sponsor

S&P Dow Jones Indices LLC, a subsidiary of The McGraw-Hill Companies, Inc., is the reference sponsor.

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-3 in the accompanying prospectus supplement and 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 or the Reference Asset itself, as applicable. 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 prospectus supplement, prospectus and Equity Index Underlying Supplement.

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;

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 Value of -10%. Accordingly, if the Reference Return is less than -10%, your Payment at Maturity will be less than the Principal Amount of your securities. You will lose up to 90% of your investment at maturity if the Reference Return is less than the Buffer Value.

The appreciation on the securities is limited by the Maximum Cap.

You will not participate in any appreciation in the level of the Reference Asset (as multiplied by the Upside Participation Rate) beyond the Maximum Cap of 12.50%. You will not receive a return on the securities greater than the Maximum Cap.

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

PS- 5

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 of the Reference Asset 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 its Reference Asset. Any such actions could affect the value of the securities.

The securities are not insured or guaranteed 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 or guaranteed 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 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 of interest may exist.

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. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset to which your securities are linked or the return on your 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 Reference Returns 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 are based on the following terms:

}	Principal Amount:	$1,000

}	Upside Participation Rate:	200%

}	Buffer Value:	-10%

}	Maximum Cap:	12.50%

Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Security
100.00%	$1,125.00	12.50%
80.00%	$1,125.00	12.50%
60.00%	$1,125.00	12.50%

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 Reference Return is 2.00%.


Reference Return:	2.00%
Final Settlement Value:	$1,040.00

Because the Reference Return is positive, and the Reference Return multiplied by the Upside Participation Rate is less than the hypothetical Maximum Cap, the Final Settlement Value would be $1,040.00 per $1,000 Principal Amount of securities, calculated as follows:

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

	= $1,000 + ($1,000 × 2.00% × 200%)

	= $1,040.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by 200% when the Reference Return is positive and, as multiplied by the Upside Participation Rate, equal to or less than the Maximum Cap.

Example 2: The Reference Return is 15.00%.


Reference Return:	15.00%
Final Settlement Value:	$1,125.00

Because the Reference Return is positive, and the Reference Return multiplied by the Upside Participation Rate is greater than the hypothetical Maximum Cap, the Final Settlement Value would be $1,125.00 per $1,000 Principal Amount of securities, calculated as follows:

	$1,000 + ($1,000 × Maximum Cap)

	= $1,000 + ($1,000 × 12.50%)

	= $1,125.00

Example 2 shows that you will receive the return of your principal investment plus a return equal to the Maximum Cap when the Reference Return is positive and the Reference Return multiplied by 200% exceeds the Maximum Cap.

Example 3: The Reference Return is -5.00%.


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

Because the Reference Return is less than zero but greater than the Buffer Value of -10%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount of securities (a zero return).

Example 3 shows that you will receive the return of your principal investment where the level of the Reference Asset declines by no more than 10% over the term of the securities.

Example 4: The Reference Return is -30.00%.


Reference Return:	-30.00%
Final Settlement Value:	$800.00

Because the Reference Return is less than the Buffer Value of -10%, the Final Settlement Value would be $800.00 per $1,000 Principal Amount of securities, calculated as follows:

	$1,000 + ($1,000 × (Reference Return + 10%))

	= $1,000 + ($1,000 × (-30.00% + 10%))

	= $800.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the level of the Reference Asset beyond the Buffer Value of -10%. YOU MAY LOSE UP TO 90% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

In no case will the sum of the underwriting discounts and referral fees exceed 2.55% per $1,000 Principal Amount.

An affiliate of HSBC has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the securities.

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 (Conflicts of Interest)” on page S-49 in the prospectus supplement.

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 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, Morrison & Foerster LLP, it is reasonable to treat a security as a pre-paid 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.

We will not attempt to ascertain whether any of the entities whose stock is included in, or owned by, the Reference Asset, as the case may be, 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, or owned by, the Reference Asset, as the case may be, 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, or owned by, the Reference Asset, as the case may be, and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in, or owned by, the Reference Asset, as the case may be, is or becomes a PFIC or a USRPHC.

Withholding and reporting requirements under the legislation enacted on March 18, 2010 (as discussed beginning on page S-48 of the prospectus supplement) will generally apply to payments made after December 31, 2013. However, this withholding tax will not be imposed on payments pursuant to obligations outstanding on January 1, 2014. Additionally, withholding due to any payment being treated as a “dividend equivalent” (as discussed beginning on page S-47 of the prospectus supplement) will begin no earlier than January 1, 2014. Holders are urged to consult with their own tax advisors regarding the possible implications of this recently enacted legislation on their investment in the securities.

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.

VALIDITY OF THE SECURITIES

In the opinion of Morrison & Foerster LLP, as counsel to the Issuer, when the securities offered by this pricing supplement have been executed and delivered by the Issuer and authenticated by the trustee pursuant to the Senior Indenture referred to in the prospectus supplement dated March 22, 2012, and issued and paid for as contemplated herein, such securities will be valid, binding and enforceable obligations of the Issuer, entitled to the benefits of the Senior Indenture, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith).
