INVESTOR SUITABILITY

The Notes may be suitable for you if:

The Notes may not be suitable for you if:

} You are willing to make an investment that provides quarterly interest payment at a fixed rate of 1.50% per annum during the Fixed Rate Payment Period and thereafter at a variable rate of 3-Month LIBOR plus the Spread, subject to the Cap and the Minimum Interest Rate. } You believe 3-Month LIBOR will generally be positive on the Coupon Determination Dates at an amount sufficient to provide you with a satisfactory return on your investment. } You are willing to invest in the Notes based on the fixed rate of 1.50% per annum during the Fixed Rate Payment Period and a Cap of 4.00% per annum during the Floating Rate Payment Period, which may limit your return on the Notes. } 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 do not seek an investment for which there will be 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.

} You are unwilling to invest in the Notes that provide quarterly interest payment at a fixed rate of 1.50% per annum during the Fixed Rate Payment Period and thereafter at a variable rate of 3-Month LIBOR plus the Spread, subject to the Cap and the Minimum Interest Rate. } You believe 3-Month LIBOR will not generally be positive on the Coupon Determination Dates at an amount sufficient to provide you with a satisfactory return on your investment. } You are unwilling to invest in the Notes based on the fixed rate of 1.50% per annum during the Fixed Rate Payment Period and a Cap of 4.00% per annum during the Floating Rate Payment Period, which may limit your return on the Notes. } 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 seek an investment for which there will be an active secondary market. } You are unable or unwilling to hold the Notes to maturity. } You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Notes.

FWP-5

Risk Factors

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 prospectus supplement and prospectus.

In addition to the following risks, you should review “Risk Factors” beginning on page S-3 in the accompanying prospectus 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.

The Coupon Rate for Each Quarterly Coupon Payment Period During the Floating Rate Payment Period Is Uncertain and Could be as Low as the Minimum Coupon Rate.

You will receive a quarterly Coupon on the applicable Coupon Payment Date during the Floating Rate Payment Period that accrues at a rate equal to 3-Month LIBOR plus the Spread, subject to the Cap of 4.00% per annum and the Minimum Coupon Rate of 0.00% per annum. 3-Month LIBOR may be influenced by a number of factors, including (but not limited to) monetary policies, fiscal policies, inflation, general economic conditions and public expectations with respect to such factors. The effect that any single factor may have on 3-Month LIBOR may be partially offset by other factors. We cannot predict the factors that may cause 3-Month LIBOR to increase or decrease. A 3-Month LIBOR that is less than or equal to zero will cause the Coupon Rate for the applicable Coupon Payment Date during the Floating Rate Payment Period to be equal to the Minimum Coupon Rate, and you will not be compensated for any loss in value due to inflation and other factors relating to the value of money over time. You should consider, among other things, the overall potential annual Coupon Rate to maturity of the Notes as compared to other investment alternatives.

The Notes Are Not Ordinary Debt Securities and the Coupon Rate is Not Fixed for any Floating Rate Payment Period and Is Variable.

The Coupon Rate is not fixed for any Floating Rate Payment Period, and will equal 3-Month LIBOR plus the Spread, subject to the Cap and the Minimum Coupon Rate, which may be less than returns otherwise payable on debt securities issued by us with similar maturities. We have no control over any fluctuations in 3-Month LIBOR.

The Notes Are Subject to the 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 the return of the Principal Amount at maturity and all Coupons, 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.

Your Coupon Rate for Each Coupon Payment Date During the Floating Rate Payment Period Is Limited by the Cap.

During the Floating Rate Payment Period, the Coupon Rate will be capped at the Cap of 4.00% per annum. As a result, you will not participate in any 3-Month LIBOR in excess of 3.25% per annum. YOUR COUPON RATE WILL NOT BE GREATER THAN THE CAP.

The Notes Are Not Insured or Guaranteed 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 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 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 amounts payable on the Notes.

Certain Built-In Costs Are Likely to Adversely Affect the Value of the Notes Prior to Maturity.

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.

FWP-6

Variable Price Reoffering Risks.

HSBC proposes to offer the Notes from time to time for sale at varying prices determined at the time of each sale. Accordingly, the price that you pay for the Notes may be higher than the prices paid by other investors based on the date and time you make your purchase, from whom you purchase the Notes (e.g., directly from HSBC or through a broker or dealer), any related transaction costs (e.g., any brokerage commission), whether you hold your Notes in a brokerage account, a fiduciary or fee-based account or another type of account and other factors beyond our control.

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 Noteseasily. 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 of Interest May Exist.

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.

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.

3-Month LIBOR, and Therefore the Value of the Notes, May be Volatile and Will Be Affected by a Number of Factors.

3-Month LIBOR, and therefore the value of the Notes is subject to volatility due to a variety of factors, including but not limited to:

· interest and yield rates in the market,

· changes in, or perceptions, about the future level of 3-Month LIBOR,

· general economic conditions,

· policies of the Federal Reserve Board regarding interest rates,

· supply and demand among banks in London for U.S. dollar-denominated deposits with approximately a three-month term,

· sentiment regarding underlying strength in the U.S. and global economies,

· expectations regarding the level of price inflation,

· sentiment regarding credit quality in the U.S. and global credit markets,

· central bank policy regarding interest rates,

· inflation and expectations concerning inflation,

· performance of capital markets,

· geopolitical conditions and economic, financial, political, regulatory or judicial events that affect markets generally and that may affect 3-Month LIBOR, and

· the time remaining to the maturity of the Notes.

The impact of any of the factors set forth above may enhance or offset some or any of the changes resulting from another factor or factors. Increases or decreases in 3-Month LIBOR could result in the corresponding Coupon Rate decreasing or a Coupon Rate equal to the Minimum Coupon Rate and thus in the reduction of the Coupon payable on the Notes.  

FWP-7

ILLUSTRATIVE EXAMPLES

The following scenario analysis 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 3-Month LIBOR and we cannot predict 3-Month LIBOR on any Coupon Determination Date. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of 3-Month LIBOR. The numbers set forth in the examples below have been rounded for ease of analysis. The following scenario analysis and examples illustrate the Coupon determination during the Floating Rate Payment Period for a $1,000.00 Principal Amount of Notes, assume that there are 90 days in each quarterly period and reflect the Cap of 4.00% per annum, the Minimum Coupon Rate of 0.00% per annum and the Spread. On each Coupon Payment Date during the Fixed Rate Payment Period, you will receive a Coupon at a Coupon Rate of 1.50% per annum, or in the amount of $3.75 per $1,000 in Principal Amount.

Hypothetical 3- Month LIBOR		Spread	Cap	Hypothetical Coupon Rate Per Annum	Hypothetical   Coupon

2.00%	+	0.75%	4.00%	2.75%	$6.875
1.50%	+	0.75%	4.00%	2.25%	$5.625
1.00%	+	0.75%	4.00%	1.75%	$4.375
0.50%	+	0.75%	4.00%	1.25%	$3.125
0.25%	+	0.75%	4.00%	1.00%	$2.500
0.00%	+	0.75%	4.00%	0.75%	$1.875
-1.25%	+	0.75%	4.00%	0.00%	$0.000
-5.00%	+	0.75%	4.00%	0.00%	$0.000
-10.00%	+	0.75%	4.00%	0.00%	$0.000

Example 1: On a Coupon Determination Date, 3-Month LIBOR is equal to 2.00%. Because 3-Month LIBOR plus 0.75% is 2.75% per annum, which is less than the Cap, the Coupon Rate for such Coupon Payment Date during the Floating Rate Payment Period is 2.75% per annum and the Coupon payment on the relevant Coupon Payment Date during the Floating Rate Payment Period would be $6.875 per $1,000 in Principal Amount calculated as follows:

1,000 × Coupon Rate × 90/360

= $1,000 × 2.75% × 90/360

= $6.875

Example 2: On a Coupon Determination Date, 3-Month LIBOR is equal to 6.00%. Because 3-Month LIBOR plus 0.75% is 6.75% per annum, which is greater than the Cap, the Coupon Rate for such Coupon Payment Date during the Floating Rate Payment Period is equal to the Cap of 4.00% per annum and the Coupon payment on the relevant Coupon Payment Date during the Floating Rate Payment Period would be $10.00 per $1,000 in Principal Amount, the maximum quarterly payment on the Notes, calculated as follows:

1,000 × Coupon Rate × 90/360

= $1,000 × 4.00% × 90/360

= $10.00

Example 3: On a Coupon Determination Date, 3-Month LIBOR is equal to -1.25%. Because 3-Month LIBOR plus 0.75% is -0.50% per annum, which is less than the Minimum Coupon Rate, the Coupon Rate for such Coupon Payment Date during the Floating Rate Payment Period is equal to the Minimum Coupon Rate of 0.00% per annum and the Coupon payment on the relevant Coupon Payment Date during the Floating Rate Payment Period would be $0.000 per $1,000 in Principal Amount, the minimum payment on the Notes, calculated as follows:

1,000 × Coupon Rate × 90/360

= $1,000 × 0.00% × 90/360

= $0.000

FWP-8

Historical Performance of 3-Month LIBOR

The following graph sets forth the historical performance of 3-Month LIBOR based on the daily historical levels from February 1, 2009 through February 24, 2015. We obtained the rates below 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 rates displayed in the graph below are for illustrative purposes only and do not form part of the calculation of the Coupon Rate on the Notes.

3-Month LIBOR, as appeared on the Bloomberg Professional^® Service on February 24, 2015 was 0.2611%. The rates reported by the Bloomberg Professional^® Service may not be indicative of 3-Month LIBOR that will be derived from the applicable Reuters page.

Historical Performance of 3-Month LIBOR

The historical 3-Month LIBOR should not be taken as an indication of future performance, and no assurance can be given as to 3-Month LIBOR relevant to any Coupon Payment Date during the Floating Rate Payment Period. We cannot give you assurance that the performance of 3-Month LIBOR will result in Coupon payments during the Floating Rate Payment Period that will provide a satisfactory return on your investment.

FWP-9

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

HSBC proposes to offer the Notes from time to time in one or more negotiated transactions at varying prices to be determined at the time of each sale.

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 varying discounts of up to 1.00% per $1,000 in Principal Amount in connection with the distribution of the Notes. HSBC Securities (USA) Inc. may sell the Notes to other broker-dealers that will participate in the offering and that are not affiliated with us, at varying discounts to the public offering price. Each of those broker-dealers may sell the notes to one or more additional broker-dealers at varying discounts. These discounts will not be greater than 1.00% per $1,000 in 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 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 make a market in the Notes 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 more than three business days following the Trade Date. 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 more than three business days prior to the Original Issue Date 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

You should carefully consider the matters set forth in “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement. We and each holder of Notes (in the absence of an administrative determination, judicial ruling or other authoritative guidance to the contrary) agree to treat the Notes for U.S. federal income tax purposes as indebtedness issued by us that is subject to the special U.S. Treasury Regulations applicable to variable rate debt instruments. Pursuant to the terms of the Notes, in the opinion of Morrison & Foerster LLP, our special U.S. tax counsel, it is reasonable to treat the Notes as variable rate debt instruments. Except to the extent of any original issue discount, interest paid on the Notes generally should be taxable to you as ordinary interest income at the time it accrues or is received in accordance with your regular method of accounting for U.S. federal income tax purposes. In addition, a U.S. holder (as defined in the accompanying prospectus supplement) must include any original issue discount in income as ordinary interest as it accrues, possibly in advance of receipt of cash attributable to such income.  The Notes may be issued with original issue discount. You should review the discussion set forth in “U.S. Federal Income Tax Considerations – U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes – Variable Rate Debt Instruments” in the accompanying prospectus supplement. In general, gain or loss realized on the sale, exchange or other disposition of the Notes will be capital gain or loss. Prospective investors should consult their tax advisors as to the federal, state, local and other tax consequences to them of the purchase, ownership and disposition of Notes.

Withholding and reporting requirements under the legislation enacted on March 18, 2010 (as discussed beginning on page S-48 of the prospectus supplement) generally apply to payments made after June 30, 2014. Holders are urged to consult with their own tax advisors regarding the possible implications of this legislation on their investment in the Notes.
