Investment in the Notes involves certain risks. You should refer to “Risk Factors” beginning on page FWP-6 of this document and page S-1 of the accompanying prospectus supplement.

The Estimated Initial Value of the Notes on the Pricing Date is expected to be between $960 and $980 per Note, which will be less than the price to public. The market value of the Notes at any time will reflect many factors and cannot be predicted with accuracy. See “Estimated Initial Value” on page FWP-3 and “Risk Factors” beginning on page FWP-6 of this document for additional information.

HSBC USA Inc. 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; provided, however, that such price will not be less than $987.50 per $1,000 in Principal Amount.

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-1 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 the CMS10, subject to the Cap of 7.00% per annum and the Minimum Coupon Rate of 0.00% per annum. The CMS10 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 the CMS10 may be partially offset by other factors. We cannot predict the factors that may cause the CMS10 to increase or decrease. If the CMS10 is less than or equal to zero, it 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 the CMS10, 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 the CMS10.

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 7.00% per annum. As a result, you will not participate in the CMS10 if it is in excess of 7.00% 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.

The Estimated Initial Value of the Notes, Which Will Be Determined by Us on the Pricing Date, Will Be Less Than the Price to Public and May Differ from the Market Value of the Notes in the Secondary Market, If Any.

The Estimated Initial Value of the Notes will be calculated by us on the Pricing Date and will be less than the price to public. The Estimated Initial Value will reflect our internal funding rate, which is the borrowing rate we pay to issue market-linked notes, as well as the mid-market value of the embedded derivatives in the Notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the

FWP-6

rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the Notes may be lower if it were based on the levels at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the Notes to be more favorable to you. We will determine the value of the embedded derivatives in the Notes by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the Notes that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your Notes in the secondary market (if any exists) at any time.

The Price of Your Notes in the Secondary Market, If Any, Immediately After the Pricing Date Will Be Less Than the Price to Public.

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes and the costs associated with structuring and hedging our obligations under the Notes. If you were to sell your Notes in the secondary market, if any, the price you would receive for your Notes may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the CMS10 and changes in market conditions, and cannot be predicted with accuracy. The Notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Notes to maturity. Any sale of the Notes prior to maturity could result in a loss to you.

If We Were to Repurchase Your Notes Immediately After the Original Issue Date, the Price You Receive May Be Higher Than the Estimated Initial Value of the Notes.

Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed the Estimated Initial Value on the Pricing Date for a temporary period expected to be approximately 24 months after the Original Issue Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes that we will no longer expect to incur over the term of the Notes. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the Notes and any agreement we may have with the distributors of the Notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

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

FWP-7

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.

The 10-year U.S. Dollar Constant Maturity Swap Rate, and Therefore the Value of the Notes, May be Volatile and Will Be Affected by a Number of Factors.

The CMS10, 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 the CMS10,

· general economic conditions,

· policies of the Federal Reserve Board regarding interest rates,

· 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 the CMS10, 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. Decreases in the CMS10 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-8

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 the CMS10 and we cannot predict the CMS10 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 the CMS10. 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 7.00% per annum and the Minimum Coupon Rate of 0.00% per annum. On each Coupon Payment Date during the Fixed Rate Payment Period, you will receive a Coupon at a Coupon Rate of 2.50% per annum, or in the amount of $6.25 per $1,000 in Principal Amount.

Hypothetical CMS10	Cap	Hypothetical Coupon Rate Per Annum	Hypothetical Coupon
10.00%	7.00%	7.00%	$17.500
9.00%	7.00%	7.00%	$17.500
8.00%	7.00%	7.00%	$17.500
7.00%	7.00%	7.00%	$17.500
6.00%	7.00%	6.00%	$15.000
5.00%	7.00%	5.00%	$12.500
4.00%	7.00%	4.00%	$10.000
3.00%	7.00%	3.00%	$7.500
2.50%	7.00%	2.50%	$6.250
2.00%	7.00%	2.00%	$5.000
1.50%	7.00%	1.50%	$3.750
1.00%	7.00%	1.00%	$2.500
0.50%	7.00%	0.50%	$1.250
0.25%	7.00%	0.25%	$0.625
0.00%	7.00%	0.00%	$0.000
-1.25%	7.00%	0.00%	$0.000
-5.00%	7.00%	0.00%	$0.000
-10.00%	7.00%	0.00%	$0.000

Example 1: On a Coupon Determination Date, the CMS10 is equal to 2.00%. Because the CMS10 is 2.00% per annum, which is less than the Cap, the Coupon Rate for such Coupon Payment Date during the Floating Rate Payment Period is 2.00% per annum and the Coupon payment on the relevant Coupon Payment Date during the Floating Rate Payment Period would be $5.00 per $1,000 in Principal Amount calculated as follows:

1,000 × Coupon Rate × 90/360

= $1,000 × 2.00% × 90/360

= $5.00

Example 2: On a Coupon Determination Date, the CMS10 is equal to 8.00%. Because the CMS10 is 8.00% 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 7.00% per annum and the Coupon payment on the relevant Coupon Payment Date during the Floating Rate Payment Period would be $17.50 per $1,000 in Principal Amount, the maximum quarterly payment on the Notes, calculated as follows:

1,000 × Coupon Rate × 90/360

= $1,000 × 7.00% × 90/360

= $17.50

Example 3: On a Coupon Determination Date, the CMS10 is equal to -1.25%. Because the CMS10 is -1.25% 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 $0.00 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

= $0.00

FWP-9

Historical Performance of THE CMS10

The following graph sets forth the historical performance of the CMS10 based on the daily historical levels from January 1, 2008 through April 16, 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.

The CMS10, as appeared on the Bloomberg Professional^® Service on April 16, 2015 was 1.9778%. The rates reported by the Bloomberg Professional^® Service may not be indicative of the CMS10 that will be derived from the applicable Reuters page.

 

Source: Bloomberg Professional^® Service

The historical CMS10 should not be taken as an indication of future performance, and no assurance can be given as to the CMS10 on any Coupon Determination Date during the Floating Rate Payment Period. We cannot give you assurance that the performance of CMS10 will result in Coupon payments during the Floating Rate Payment Period that will provide a satisfactory return on your investment.

FWP-10

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 1.25% 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 1.25% 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-59 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 may be 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 – Tax Treatment of U.S. Holders – U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes – Notes that are VRDIs” 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.
