The Securities

The securities are designed for investors who believe the Reference Asset will appreciate over the term of the securities. If the Reference Return is below the Buffer Level, then the securities are subject to the Downside Leverage Factor, resulting in 1.25x exposure to any potential decline of the Reference Asset beyond the Buffer Level of -20%.

If the Reference Asset appreciates over the term of the securities, you will realize a return equal to at least 120% (1.20x) (to be determined on the Pricing Date) of the Reference Asset appreciation. Should the Reference Asset decline, you will lose 1.25% of your investment for every 1% decline in the Reference Asset beyond the Buffer Level.

If the Reference Return is less than the Buffer Level, the return on your securities will be negative, and despite the inclusion of the Buffer Level, due to the Downside Leverage Factor you may lose 100% of your investment.

The offering period for the securities is through May 20, 2016

Payoff Example

The table at right shows the hypothetical payout profile of an investment in the securities assuming an Upside Participation Rate of at least 120% (1.20x) (to be determined on the Pricing Date) and reflecting the Buffer Level of -20% and the Downside Leverage Factor of 1.25x.

We reserve the right to withdraw, cancel or modify this offering and to reject orders in whole or in part.

You should read this document together with the prospectus dated March 5, 2015, the prospectus supplement dated March 5, 2015 and the Equity Index Underlying Supplement dated March 5, 2015. If the terms of the securities offered hereby are inconsistent with those described in the accompanying prospectus, prospectus supplement or Equity Index Underlying Supplement, the terms described in this free writing prospectus shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page FWP-7 of this free writing prospectus, page S-1 of the prospectus supplement and page S-2 of the Equity Index Underlying Supplement, as the securities involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, prospectus supplement and Equity Index Underlying Supplement) with the SEC for the offering to which this free writing prospectus relates.

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:

If the Reference Return is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Reference Return × Upside Participation Rate*).

*To be determined on the Pricing Date and will not be less than 120%.

If the Reference Return is less than or equal to zero but greater than or equal to the Buffer Level, you will receive $1,000 per $1,000 Principal Amount (zero return).

If the Reference Return is less than the Buffer Level, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 20%) x Downside Leverage Factor].

Under these circumstances, you will lose 1.25% of the Principal Amount of your securities for each percentage point that the Reference Return is below the Buffer Level. For example, if the Reference Return is -30%, you will suffer a 12.50% loss and receive 87.50%of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the Reference Return is less than the Buffer Level, you may lose up to 100% of your investment.

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 level of the Reference Asset will increase over the term of the securities.

You are willing to make an investment that is exposed to the Downside Leverage Factor of 1.25x for each percentage point that the Reference Return is below the Buffer Level of -20% and you understand that the leverage factor may magnify your losses up to a 100% loss of your investment..

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 securities to maturity.

You are unwilling to make an investment that is exposed to the Downside Leverage Factor of 1.25x for each percentage point that the Reference Return is below the Buffer Level of -20%, up to a 100% loss of your investment.

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-6

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page S-2 of the accompanying 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, prospectus supplement 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 if the Reference Return is negative. You will be exposed on a leveraged basis to any decline in the Final Level from the Initial Level beyond the Buffer Level of -20%, which will magnify your losses up to 100% loss of your investment. Accordingly, if the Reference Return is less than the Buffer Level of -20%, your Payment at Maturity will be less than the Principal Amount of your securities. You may lose up to 100% of your investment at maturity if the Reference Return is less than the Buffer Level.

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

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

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.

The securities will not bear interest.

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

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 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 securities and the return on 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.

FWP-7

The Estimated Initial Value of the securities, 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 securities in the secondary market, if any.

The Estimated Initial Value of the securities 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 securities, as well as the mid-market value of the embedded derivatives in the securities. 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 rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the securities 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 securities to be more favorable to you. We will determine the value of the embedded derivatives in the securities 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 securities 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 securities in the secondary market (if any exists) at any time.

The price of your securities 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 securities and the costs associated with structuring and hedging our obligations under the securities. If you were to sell your securities in the secondary market, if any, the price you would receive for your securities 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 securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Reference Asset and changes in market conditions, and cannot be predicted with accuracy. The securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the securities to maturity. Any sale of the securities prior to maturity could result in a loss to you.

If we were to repurchase your securities immediately after the Original Issue Date, the price you receive may be higher than the Estimated Initial Value of the securities.

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 securities 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 9 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 securities and other costs in connection with the securities that we will no longer expect to incur over the term of the securities. 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 securities and any agreement we may have with the distributors of the securities. 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 securities based on changes in market conditions and other factors that cannot be predicted.

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.

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.

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 of the Reference Asset. 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 such a security 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 Securities” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount 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:

4	Principal Amount:	$1,000

4	Hypothetical Initial Level:	2,000.00

4	Hypothetical Upside Participation Rate*:	120%

4	Downside Leverage Factor:	1.25x

4	Buffer Level:	-20%

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

*To be determined on the Pricing Date and will not be less than 120%.

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 level of the Reference Asset increases from the Initial Level of 2,000.00 to a Final Level of 2,200.00.


Reference Return:	10.00%
Final Settlement Value:	$1,120.00

Because the Reference Return is positive, the Final Settlement Value would be $1,120.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Reference Return × Upside Participation Rate)

= $1,000 + ($1,000 × 10.00% ×120%)

= $1,120.00

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 of 120% when the Reference Asset appreciates.

Example 2: The level of the Reference Asset decreases from the Initial Level of 2,000.00 to a Final Level of 1,900.00.


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

Because the Reference Return is less than zero but greater than the Buffer Level of -20%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 3: The level of the Reference Asset decreases from the Initial Level of 2,000.00 to a Final Level of 1,000.00


Reference Return:	-50.00%
Final Settlement Value:	$625.00

Because the Reference Return is less than the Buffer Level of -20%, the Final Settlement Value would be $625.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 20%) × Downside Leverage Factor]

= $1,000 + [$1,000 × (-50.00% + 20%) × 1.25]

= $625.00

Example 3 shows that you are exposed on leveraged basis to declines in the level of the Reference Asset beyond the Buffer Level of -20%. YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

THE S&P 500^® Index (“SPX”)

Description of the SPX

The SPX is a capitalization-weighted index of 500 U.S. stocks. It is designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries.

The top 5 industry groups by market capitalization as of May 10, 2016 were: Information Technology, Financials, Health Care, Consumer Discretionary and Consumer Staples.

For more information about the SPX, see “S&P 500^® Index” on page S-44 of the accompanying Equity Index Underlying Supplement.

Historical Performance of the SPX

The following graph sets forth the historical performance of the SPX based on the daily historical closing levels from January 1, 2008 through May 10, 2016. The closing level for the SPX on May 10, 2016 was 2,084.39. We obtained the closing levels 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 historical levels of the SPX should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the SPX on the Final Valuation Date.

EVENTS OF DEFAULT AND ACCELERATION

If the securities have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the securities, 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 immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the Reference Return, and the accelerated maturity date will be three business days after the accelerated Final Valuation Date. 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 securities have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the securities. 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 securities. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the securities 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 securities directly to investors. HSBC Securities (USA) Inc. proposes to offer the securities 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 0.55% and referral fees of up to 1.60% per $1,000 Principal Amount in connection with the distribution of the securities to other registered broker-dealers. In no case will the sum of the underwriting discounts and referral fees exceed 1.60% per $1,000 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 securities.

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 securities, but is under no obligation to make a market in the securities 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.

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.

Under current law, while the matter is not entirely clear, individual non-U.S. holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, the securities are likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in the securities.

Recently finalized Treasury Regulations provide that withholding on “dividend equivalent” payments (as discussed in the accompanying prospectus supplement), if any, will not apply to securities issued before January 1, 2017. Additionally, the IRS has announced that withholding under the Foreign Account Tax Compliance Act (as discussed in the accompanying prospectus supplement) on payments of gross proceeds from a sale, exchange, redemption or other disposition of the securities will only apply to dispositions after December 31, 2018.

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.
