For investors who seek a particular Market Exposure and who believe the Reference Asset will appreciate over the term of the AMPS, the AMPS provide an opportunity for accelerated returns. If the Reference Return is negative, then the AMPS provide 1:1 exposure to any potential decline in the value of the Reference Asset.

If the Reference Asset appreciates over the term of the securities, you will realize a return equal to 190% to 210% (to be determined on the Pricing Date) of the Reference Asset appreciation. If the Reference Asset declines, you will lose 1% of your investment for every 1% decline in the value of the Reference Asset.

The S&P 500^® Low Volatility Index

The S&P 500^® Low Volatility Index (the “Index”) is designed to serve as a benchmark for low volatility strategies in the U.S. stock market.

The volatilities of all S&P 500^® Index constituents are calculated using data for approximately the past year. Constituents are ranked in order of their volatility and the 100 least volatile stocks are included in the index.

Weightings are assigned according to their volatilities, with the least volatile stocks receiving the highest weighting. The Index is rebalanced in February, May, August and November of each year. Please see FWP-13 for more information about the Index.

The offering period for the AMPS is through May 23, 2013

S&P 500® Low Volatility Index
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 February 2013 rebalancing, the sector weightings in the SP5LVI were as follows: Consumer Discretionary: 2.78%, Consumer Staples: 27.31%, Energy: 1.80%, Financials: 10.65%, Healthcare: 11.58%, Industrials: 6.32%, Information Technology: 3.61%, Materials: 2.55%, Telecommunication Services: 2.76% and Utilities: 30.64%.

Information about the Reference Asset

The graph above sets forth the hypothetical back-tested performance of the Reference Asset from April 26, 2008 through April 19, 2011 and the historical performance of the Reference Asset from April 20, 2011 to April 26, 2013. The Reference Asset has only been calculated since April 20, 2011. The hypothetical back-tested performance of the Index set forth in the graph above was calculated using the same selection criteria and methodology employed to calculate the Reference Asset since its inception on April 20, 2011. However, the hypothetical back-tested Reference Asset data only reflects the application of that methodology in hindsight, since the Reference Asset was not actually calculated and published prior to April 20, 2011. The hypothetical back-tested Reference Asset data cannot completely account for the impact of financial risk in actual trading. There are numerous factors related to the equities markets in general that cannot be, and have not been, accounted for in the hypothetical back-tested Reference Asset data, all of which can affect actual performance. Consequently, you should not rely on that data as a reflection of what the actual Reference Asset performance would have been had the index been in existence or in forecasting future Reference Asset performance. Because the Reference Asset is a price return index, and not a total return index, the data presented above does not reflect the payment of dividends. The graph above also reflects the actual closing levels from April 20, 2011 to April 26, 2013 that we obtained from the Bloomberg Professional^® service. The hypothetical and actual historical performance is not necessarily an indication of future results. For further information on the Reference Asset, please see “The S&P 500^® Low Volatility Index” on page FWP-13 and in the accompanying Equity Index Underlying Supplement. We have derived all disclosure regarding the Reference Asset from publicly available information. Neither HSBC USA Inc. nor any of its affiliates have undertaken any independent review of, or made any due diligence inquiry with respect to, the publicly available information about the Reference Asset.

For more information about SP5LVI, please refer to the fact sheet: http://www.sec.gov/Archives/edgar/data/83246/000114420412016831/v306941_fwp.htm.

The tables below are a comparison of the 1997 through 2012 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 and in the Equity Index Underlying Supplement, 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. Because the Reference Asset is a price return index, and not a total return index, the return data presented below does not reflect the payment of dividends.

¹ Annual Return is a return an investment provides over a period of one year, expressed as (a) the difference between ending level and starting level, divided by (b) the starting level.			² Annualized return is a return an investment provides over a period of time, representing a geometric average of annual returns over that period. The geometric average of annual returns represents the average rate per year on an investment that is compounded over a period of several years. ³ Standard Deviation is a statistical measure of the distance a quantity is likely to lie from its average value. In finance, standard deviation is applied to the annual rate of return of an investment, to measure the investment's volatility, or “risk”.

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:

$1,000 + ($1,000 × Reference Return).

Under these circumstances, you will lose 1% of the Principal Amount for each percentage point that the Reference Return is negative.

A “business day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in the City of New York.

Payment When Offices or Settlement Systems Are Closed

If any payment is due on the securities on a day that would otherwise be a “business day” but is a day on which the office of a paying agent or a settlement system is closed, we will make the payment on the next business day when that paying agent or system is open. Any such payment will be deemed to have been made on the original due date, and no additional payment will be made on account of the delay.

Reference Sponsor

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

FWP-7

INVESTOR SUITABILITY

The securities may be suitable for you if:

} You seek an investment with an enhanced return linked to the potential positive performance of the Reference Asset and you believe the value 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 zero.

} 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 forego 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 securities to maturity.

} You are comfortable with the creditworthiness of HSBC, as Issuer of the securities.

The securities may not be suitable for you if:

} You believe the Reference Return will be negative on the Final Valuation Date 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 less than zero.

} 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 the 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.

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. 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 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; 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.

The securities do not guarantee any return of principal. You will be exposed to the decline in the Final Value from the Initial Value. Accordingly, if the Reference Return is less than 0%, your Payment at Maturity will be less than the Principal Amount. You will lose up to 100% 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.

FWP-8

The securities will not bear interest.

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

The Reference Asset has limited actual historical information.

The Reference Asset was created in April 2011. The reference sponsor has published limited actual information about how the Reference Asset would have performed had it been calculated in the past. Because the Reference Asset is of recent origin and limited actual historical performance data exists with respect to it, your investment in the securities may involve a greater risk than investing in securities linked to one or more indices with a more established record of performance.

A low volatility index may be volatile.

While the Reference Asset has been designed in part to mitigate the effects of volatility, there is no assurance that it will be successful in doing so. It is also possible that the features of the Reference Asset designed to address the effects of volatility will instead adversely affect the return of the Reference Asset and, consequently, the return on the securities.

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 value of the Reference Asset. The policies of the reference sponsor with respect to the calculation of the Reference Asset could also affect the value 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 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 free writing prospectus is based on the full Principal Amount, 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.

The amount payable on the securities is not linked to the value of Reference Asset at any time other than on the Final Valuation Date.

The Final Value will be based on the Official Closing Value of the Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the value of the Reference Asset appreciates prior to the Final Valuation Date but then decreases on the Final Valuation Date to a value that is less than the Initial Value, the Payment at Maturity will be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the value of the Reference Asset prior to such decrease. Although the actual value of the Reference

FWP-9

Asset on the stated Maturity Date or at other times during the term of the securities may be higher than the Final Value, the Payment at Maturity will be based solely on the Official Closing Value of the Reference Asset on the Final Valuation Date.

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.

FWP-10

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 value of the Reference Asset relative to its Initial Value. We cannot predict the Final Value 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 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 assume the following:

}	Principal Amount:	$1,000
}	Hypothetical Upside Participation Rate:	200% (the actual Upside Participation Rate will be determined on the Pricing Date and will not be less than 190% or greater than 210%)

Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Security
100.00%	$3,000.00	200.00%
80.00%	$2,600.00	160.00%
60.00%	$2,200.00	120.00%

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, 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 the hypothetical Upside Participation Rate when such Reference Return is positive.

Example 2: The Reference Return is -30.00%.

Reference Return:	-30.00%
Final Settlement Value:	$700.00

Because the Reference Return is negative, the Final Settlement Value would be $700.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Reference Return)

= $1,000 + ($1,000 × -30.00%)

= $700.00

Example 2 shows that you are exposed on a 1-to-1 basis to declines in the value of the Reference Asset below zero. YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

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.

There are two steps in the creation of the Index:

Constituent selection: The volatilities of all S&P 500^® Index constituents are calculated using daily standard deviation data for approximately the past year. Constituents are ranked in order of their realized volatility. The Index comprises the 100 least volatile stocks.

Constituent weighting: At each rebalancing, the weight for each Index constituent is set inversely proportional to its volatility (higher weightings are assigned to the least volatile stocks). The Index is rebalanced in February, May, August and November of each year.

As of the February 2013 rebalancing, the sector weightings in the SP5LVI were as follows: Consumer Discretionary: 2.78%, Consumer Staples: 27.31%, Energy: 1.80%, Financials: 10.65%, Healthcare: 11.58%, Industrials: 6.32%, Information Technology: 3.61%, Materials: 2.55%, Telecommunication Services: 2.76% and Utilities: 30.64%.

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

Hypothetical and Actual Historical Performance of the SP5LVI

The following graph sets forth the hypothetical back-tested performance of the SP5LVI from April 26, 2008 through April 19, 2011 and the historical performance of the SP5LVI from April 20, 2011 to April 26, 2013. 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. However, the hypothetical back-tested SP5LVI data only reflects the application of that methodology in hindsight, since the SP5LVI was not actually calculated and published prior to April 20, 2011. The hypothetical back-tested SP5LVI data cannot completely account for the impact of financial risk in actual trading. There are numerous factors related to the equities markets in general that cannot be, and have not been, accounted for in the hypothetical back-tested SP5LVI data, all of which can affect actual performance. Consequently, you should not rely on that data as a reflection of what the actual SP5LVI performance would have been had the index been in existence or in forecasting future SP5LVI performance. Because the SP5LVI is a price return index, and not a total return index, the data presented below does not reflect the payment of dividends. The graph below also reflects the actual closing levels from April 20, 2011 to April 26, 2013 that we obtained from the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service. The closing level for the SP5LVI on April 26, 2013 was 5,132.59. 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 2012 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 and in the Equity Index Underlying Supplement, 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. Because the SP5LVI is a price return index, and not a total return index, the return data presented below does not reflect the payment of dividends.

³ Standard Deviation is a statistical measure of the distance a quantity is likely to lie from its average value. In finance, standard deviation is applied to the annual rate of return of an investment, to measure the investment's volatility, or “risk”.

Sector Weightings

The table below shows the current weight, average weight and maximum weight of each industry sector included in the SP5LVI. 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 and in the Equity Index Underlying Supplement, the SP5LVI was not actually calculated and published prior to April 20, 2011. No assurance can be given that these weightings will not change.

 

The hypothetical back-tested weights of the SP5LVI set forth above were calculated using the selection criteria and methodology employed to calculate the SP5LVI since its inception on April 20, 2011.

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.
