We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

Interest

The Notes will not pay interest.

Official Closing Level

With respect to each Underlying, the Official Closing Level on any trading day will be determined by the calculation agent based upon the closing level of such index, displayed on the following pages on Bloomberg Professional^® service: for SPX, page “SPX <INDEX>”, and for RTY page “RTY <INDEX>”.

FWP-6

INVESTOR SUITABILITY

The Notes may not be suitable for you if:

} You believe that the Official Closing Level of both of the Underlyings will not decline by more than 30%, as compared to the Initial Level, on the Final Valuation Date.

} You are willing to make an investment that is potentially exposed to downside performance of the Least Performing Underlying on a 1-to-1 basis for each percentage point that its Reference Return is less than zero if such Reference Return is less than the Barrier Level.

} You are willing to invest in the Notes based on the Maximum Upside Return indicated herein, which will limit your return at maturity.

} 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 unwilling to make an investment that is potentially exposed to downside performance of the Least Performing Underlying on a 1-to-1 basis for each percentage point that its Reference Return is less than zero if such Reference Return is less than the Barrier Level.

} 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.

FWP-7

RISK FACTORS

We urge you to read the section “Risk Factors” 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;

}

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

}

“—Small-Capitalization or Mid-Capitalization Companies Risk” in the Equity Index Underlying Supplement.

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

The Notes do not guarantee return of principal and you may lose your entire initial investment.

The Notes do not guarantee return of principal. The Notes differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount of your Notes if the Reference Return of the Least Performing Underlying is below the Barrier Level of 70%. In this case, the Payment at Maturity you will be entitled to receive will be less than the Principal Amount of the Notes and you could lose your entire initial investment if the level of the Least Performing Underlying falls to zero. An investment in the Notes is not principal protected and you may receive less at maturity than you originally invested in the Notes, or you may receive nothing at maturity. Payment of any amount at maturity is subject to the credit risk of HSBC.

The appreciation on the Notes is limited by the Maximum Upside Return.

You will not participate in any appreciation in the level of the Reference Asset beyond the Maximum Upside Return of 12.00%. You will not receive a return on the Notes greater than the Maximum Upside Return.

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.

Since the Notes are linked to the performance of more than one Underlying, you will be fully exposed to the risk of fluctuations in the levels of each Underlying.

Since the Notes are linked to the performance of more than one Underlying, the Notes will be linked to the individual performance of each Underlying. Because the Notes are not linked to a weighted basket, in which the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the prices of the Underlyings to the same degree for each Underlying. For example, in the case of Notes linked to a weighted basket, the return would depend on the weighted aggregate performance of the basket components reflected as the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component, as scaled by the weightings of such basket components. However, in the case of these Notes, the individual performance of each of the Underlyings would not be combined to calculate your return and the depreciation of either Underlying would not be mitigated by the appreciation of the other Underlying. Instead, your return would depend on the Least Performing Underlying of the two Underlyings to which the Notes are linked.

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 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 Notes.

FWP-8

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 placement 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 securities 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.

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 a Note, 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-9

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 any Underlying relative to its Initial Level. We cannot predict the Final Level of either Underlying. 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 Underlying. 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. With respect to the 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 Payment at Maturity on a $1,000 investment in the Notes for a hypothetical range of performance for the Least Performing Underlying’s Reference Return 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 Payment at Maturity 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 of Least Performing Underlying:	800.00
}	Maximum Upside Return:	12.00%
}	Barrier Level:	70% of the Initial Level of each Underlying

The actual Initial Level with respect to each Underlying will be determined on the Pricing Date.

FWP-10

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 Least Performing Underlying increases from the Initial Level of 800.00 to a Final Level of 840.00.


Reference Return:	5.00%
Final Settlement Value:	$1,120.00

Because the Reference Return of the Least Performing Underlying is positive, the investor receives the Maximum Upside Return and the Final Settlement Value would be $1,120.00 per $1,000 Principal Amount of Notes, calculated as follows:

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

= $1,000 + ($1,000 × 12.00%)

= $1,120.00

Example 1 shows that you will benefit from the Maximum Upside Return at maturity when the Reference Return of the Least Performing Underlying is zero or positive.

Example 2: The level of the Least Performing Underlying increases from the Initial Level of 800.00 to a Final Level of 1,280.00.


Reference Return:	60.00%
Final Settlement Value:	$1,120.00

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

= $1,000 + ($1,000 × 12.00%)

= $1,120.00

Example 2 shows that you will receive the return of your principal investment plus a return equal to the Maximum Upside Return at maturity when the Reference Return of the Least Performing Underlying is greater than or equal to zero, but you will not participate in any increase in the Reference Return of the Least Performing Underlying above the Maximum Upside Return.

Example 3: The level of the Least Performing Underlying decreases from the Initial Level of 800.00 to a Final Level of 760.00.


Reference Return:	-5.00%
Final Settlement Value:	$1,120.00

Although the Reference Return of the Least Performing Underlying is negative, since the Reference Return is greater than the Barrier Level the investor receives the Maximum Upside Return and the Final Settlement Value would be $1,120.00 per $1,000 Principal Amount of Notes, calculated as follows:

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

= $1,000 + ($1,000 × 12.00%)

= $1,120.00

Example 3 shows that you will receive the return of your principal investment plus a return equal to the Maximum Upside Return at maturity when the Reference Return of the Least Performing Underlying is less than zero but greater than or equal to the Barrier Level.

Example 4: The level of the Least Performing Underlying decreases from the Initial Level of 800.00 to a Final Level of 480.00.


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

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

$1,000 + ($1,000 × Least Performing Underlying’s Reference Return)

FWP-11

= $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 Reference Return of the Least Performing Underlying below zero when the Reference Return of the Least Performing Underlying is less than the Barrier Level. YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR NOTES.

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 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 offering price set forth on the cover page of this free writing prospectus. HSBC USA Inc. or one of our affiliates may pay varying discounts of up to 1.50% per $1,000 Principal Amount of Notes in connection with the distribution of the Notes to other registered broker-dealers.

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 securities on or about the Original Issue Date set forth on page FWP-4 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, 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 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 forward or other 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, Sidley Austin llp, it is reasonable to treat a Note 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 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. 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.
