The Notes

These Digital-Plus Barrier Notes may be suitable for investors who believe that the Reference Asset will appreciate over the term of the notes. So long as the Reference Return is below the Minimum Upside Return and above the Barrier Level at maturity, the notes will outperform the Reference Return.

If the Reference Return is greater than or equal to zero, you will realize at least the Minimum Upside Return at maturity (subject to the credit risk of HSBC). If the Reference Return exceeds the Minimum Upside Return, the notes will provide a one-for-one return based on the percentage increase of the Reference Asset. If the Reference Return is less than zero but equal to or greater than -30%, you will receive your principal amount. If the Reference Asset declines by more than 30%, you will lose 1% of your investment for every 1% decline in the Reference Asset.

The offering period for the notes is through April 19, 2013

FWP-2

Payoff Example
The table at right shows the hypothetical payout profile of an investment in the notes reflecting a hypothetical Minimum Upside Return of 20.00%.  The actual Minimum Upside Return will be determined on the Pricing Date and will not be less than 20.00% or greater than 25.00%.

INVESTOR SUITABILITY

The notes may be suitable for you if:

The notes 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 not change or will increase over the term of the notes. } You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis if the Reference Return is less than -30%. } You are willing to accept the risk and return profile of the notes 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 the 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 notes to maturity. } You are comfortable with the creditworthiness of HSBC, as Issuer of the notes.

FWP-6

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 notes is not equivalent to investing directly in any of the stocks comprising the Reference Asset. You should understand the risks of investing in the notes and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the notes in light of your particular financial circumstances and the information set forth in this free writing prospectus 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 notes 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 notes may result in a loss.

You will be fully exposed to the decline in the Final Level from the Initial Level if the Reference Return is beyond the Barrier 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 notes. You may lose up to 100% of your investment at maturity if the Reference Return is negative.

Credit risk of HSBC USA Inc.

The notes 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 notes 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 notes, 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 notes 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 notes.

The notes will not bear interest.

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

Changes that affect the Reference Asset will affect the market value of the notes 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 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 notes.

The notes are not insured by any governmental agency of the United States or any other jurisdiction.

The notes 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 notes 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 notes.

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

While the Payment at Maturity described in this free writing prospectus is based on the full Principal Amount of your notes, the original issue price of the notes includes the agent’s commission and the estimated cost of HSBC hedging its obligations under the notes. As a result, the price, if any, at which HSBC Securities (USA) Inc. will be willing to purchase notes 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 notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

The notes lack liquidity.

The notes will not be listed on any notes exchange. HSBC Securities (USA) Inc. is not required to offer to purchase the notes 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 notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the notes.

FWP-7

Potential conflicts.

HSBC and its affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and hedging our obligations under the notes. 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 notes. We will not have any obligation to consider your interests as a holder of the notes in taking any action that might affect the value of your notes.

Uncertain tax treatment.

For a discussion of the U.S. federal income tax consequences of your investment in the notes, 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.

FWP-8

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 expected to be 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 notes. 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 Final Settlement Value on a $1,000 investment in the notes 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 Note” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount of notes to $1,000. The potential returns described here assume that your notes are held to maturity. You should consider carefully whether the notes are suitable to your investment goals. The following table and examples assume the following:

}	Principal Amount:	$1,000
}	Hypothetical Initial Level:	1,500.00
}	Hypothetical Minimum Upside Return:	20.00% (The actual Minimum Upside Return will be determined on the Pricing Date and will not be less than 20.00% or greater than 25.00%).

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

FWP-9

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

Example 1: The level of the Reference Asset increases from the Initial Level of 1,500.00 to a Final Level of 1,575.00.

Reference Return:	5.00%
Final Settlement Value:	$1,200.00

Because the Reference Return is positive, and such Reference Return is less than the hypothetical Minimum Upside Return, the investor receives the Minimum Upside Return, and the Final Settlement Value would be $1,200.00 per $1,000 Principal Amount of notes, calculated as follows:

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

= $1,000 + ($1,000 × 20.00%)

= $1,200.00

Example 1 shows that you will benefit from the Minimum Upside Return at maturity when the Reference Return is positive but less than the Minimum Upside Return.

Example 2: The level of the Reference Asset increases from the Initial Level of 1,500.00 to a Final Level of 2,400.00.

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

Because the Reference Return is positive, and such Reference Return is greater than the Minimum Upside Return, the Final Settlement Value would be $1,600.00 per $1,000 Principal Amount of notes, calculated as follows:

$1,000 + ($1,000 × Reference Return)

= $1,000 + ($1,000 × 60.00%)

= $1,600.00

Example 2 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 positive and greater than the Minimum Upside Return.

Example 3: The level of the Reference Asset decreases from the Initial Level of 1,500.00 to a Final Level of 1,425.00.

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

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

Example 4: The level of the Reference Asset decreases from the Initial Level of 1,500.00 to a Final Level of 900.00.

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

Because the Reference Return is less than the Barrier Level of -30%, the Final Settlement Value would be $600.00 per $1,000 Principal Amount of notes, calculated as follows:

$1,000 + ($1,000 × Reference Return)

= $1,000 + ($1,000 × -40.00%)

= $600.00

Example 4 shows that you are fully exposed on a 1-to-1 basis to declines in the level of the Reference Asset if the Reference Return is beyond the Barrier Level of -30%. YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR NOTES.

Historical Performance of the SPX   The following graph sets forth the historical performance of the SPX based on the daily historical closing levels from March 26, 2008 through March 26, 2013. The closing level for the SPX on March 26, 2013 was 1,563.77. We obtained the closing levels below from the Bloomberg Professional^® service.

EVENTS OF DEFAULT AND ACCELERATION

If the notes have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the notes, the Calculation Agent will determine the accelerated payment due and payable at maturity in the same general manner as described in “Payment at Maturity” 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 Reference Return.  If a Market Disruption Event exists with respect to the Reference Asset on that scheduled trading day, then the accelerated Final Valuation Date for the Reference Asset will be postponed for up to five scheduled trading days (in the same manner used for postponing the originally scheduled Final Valuation Date).  The accelerated Maturity Date will also be postponed by an equal number of business days.

If the notes have become immediately due and payable following an event of default, you will not be entitled to any additional payments with respect to the notes. For more information, see “Description of Debt Securities — Senior Debt Securities — Events of Default” in the accompanying prospectus.

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 notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the notes from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this free writing prospectus relates, for distribution to other registered broker-dealers or will offer the notes directly to investors. HSBC Securities (USA) Inc. proposes to offer the notes at the price to public set forth on the cover page of this free writing prospectus. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 2.75% per $1,000 Principal Amount of notes in connection with the distribution of the notes to other registered broker-dealers.

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 notes.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the notes, 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.

We expect that delivery of the notes will be made against payment for the notes on or about the Original Issue Date set forth on the inside cover page of this document, which is expected to be the fifth business day following the Trade Date of the notes. Under Rule 15c6-1 under the Securities Exchange Act of 1934, 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 the notes 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 notes, and therefore significant aspects of the tax treatment of the notes are uncertain as to both the timing and character of any inclusion in income in respect of the notes. Under one approach, a note should be treated as a pre-paid executory contract with respect to the Reference Asset. We intend to treat the notes consistent with this approach. Pursuant to the terms of the notes, you agree to treat the notes 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 note 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 notes 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 note 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.

FWP-12

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 notes.

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