The Notes

The Notes may be suitable for investors who believe the level of both Underlyings will not decrease by more than 20% from the pricing date to the Final Valuation Date.

If both Underlyings are at or above their respective Initial Levels on any Call Observation Date, your Notes will be automatically called and you will receive a return equal to the applicable Call Premium.

If the Notes are not automatically called and the Final Level of the Least Performing Underlying is greater than or equal to its Buffer Level, you will receive a return equal to the Rebate Return.

If the Notes are not automatically called and the Final Level of the Least Performing Underlying is less than its Buffer Level, you will lose 1.25% of your principal for every 1% decline in level of the Least Performing Underlying beyond -20%.

The offering period for the Notes is through December 15, 2015

FWP-2

Illustration of Payment Scenarios

Your payment on the Notes will depend on whether the Notes have been automatically called and, if they have not been called, whether the Final Level of the Least Performing Underlying is below its Buffer Level.

PAYMENT ON THE NOTES

Call Feature

The Notes will be automatically called if the Official Closing Level of each Underlying is at or above its Initial Level on any Call Observation Date. If the Notes are automatically called, investors will receive the applicable Call Price on the corresponding Call Payment Date.

Maturity

Unless the Notes are automatically called, on the Maturity Date and for each $1,000 Principal Amount of Notes, you will receive a cash payment equal to the Final Settlement Level determined as follows:

n If the Final Return of the Least Performing Underlying is less than zero but greater than or equal to -20%:

$1,000 + ($1,000 x Rebate Return)

n If the Final Return of the Least Performing Underlying is less than -20%:

$1,000 + [$1,000 × (Final Return of the Least Performing Underlying + 20%) x Downside Leverage Factor]

For example, if the Final Return of the Least Performing Underlying is -30%, you will suffer a 12.50% loss and receive 87.50% of the Principal Amount. If the Final Level of the Least Performing Underlying is less than the Buffer Level, you will lose up to 100% of the Principal Amount.

Official Closing Level

The closing level of the Underlying on any scheduled trading day as determined by the calculation agent based upon the level displayed on the relevant Bloomberg Professional^® service page (with respect to the RTY, “RTY <INDEX>,” and with respect to the SPX, “SPX <INDEX>”), or, for each Underlying, any successor page on the Bloomberg Professional^® service or any successor service, as applicable.

FWP-6

The Notes may not be suitable for you if:

FWP-8

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 in the accompanying prospectus supplement, beginning 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 included in any Underlying. 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, 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 Notes 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.

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

The Notes do not guarantee any 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 Notes are not automatically called and the Final Level of the Least Performing Underlying is less than its Buffer Level. 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 will lose 1.25% for each 1% that the Final Return of the Least Performing Underlying is less than -20%. You may lose up to 100% of your investment at maturity.

You will not participate in any appreciation in the level of any of the Underlyings included in the Reference Asset.

The Notes will not pay more than the Principal Amount, plus any unpaid call payment, at maturity or if the Notes are automatically called. Even if the Final Return of each Underlying in the Reference Asset is greater than zero, you will not participate in the appreciation of any Underlying. Assuming the Notes are held to maturity, the maximum amount payable with respect to the Notes will not exceed the sum of the Principal Amount plus any call payments. Under no circumstances, regardless of the extent to which the level of any Underlying appreciates, will your return exceed the total amount of the call payments. In some cases, you may earn significantly less by investing in the Notes than you would have earned by investing in an instrument directly linked to the performance of the Underlyings included in the Reference Asset.

Your return on the Notes is limited.

Your potential gain on the Notes will be limited to the Call Premium applicable to a Call Observation Date or the Rebate Return, regardless of the appreciation in the Underlyings, which may be significant. You will not receive a return on the Notes greater than the Call Premiums or the Rebate Return, as applicable.

The Notes will not bear interest.

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

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 any return of principal at maturity or upon early redemption, as applicable, 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.

If the Notes are not called, your return will be based on the Final Return of the Least Performing Underlying.

If the Notes are not automatically called, your return will be based on the Final Return of the Least Performing Underlying without regard to the performance of the other Underlying. As a result, you could lose all or some of your initial investment if the Final Level of the Least Performing Underlying is less than its Buffer Level, even if there is an increase in the level of the other Underlying. This could be the case even if the other Underlying increased by an amount greater than the decrease in the Least Performing Underlying.

FWP-9

The Notes may be automatically called prior to the Maturity Date.

If the Notes are automatically called, the holding period over which you will receive the applicable Call Premium could be as little as six months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are automatically called prior to the Maturity Date.

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 level 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 levels 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 one Underlying would not be mitigated by the appreciation of the other Underlying. Instead, your return would depend on the Least Performing Underlying.

Changes that affect the Underlyings may affect the market value of the Notes and the amount you will receive at maturity.

The policies of the reference sponsor of the relevant Underlying concerning additions, deletions and substitutions of the constituents comprising such Underlying and the manner in which the reference sponsor takes account of certain changes affecting those constituents included in such Underlying may affect the level of that Underlying. The policies of the reference sponsor with respect to the calculation of the relevant Underlying could also affect the level of such Underlying. The reference sponsor may discontinue or suspend calculation or dissemination of its relevant Underlying. Any such actions could affect the value of the Notes and the return on the Notes.

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 full Payment at Maturity 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 securities, 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 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 levels of the Underlyings 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.

FWP-10

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 3 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.

The amount payable on the Notes is not linked to the levels of the Underlyings at any time other than the Call Observation Dates and the Final Valuation Date.

The payments on the Notes will be based on the Official Closing Levels of the Underlyings on the Call Observation Dates, including the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the level of each Underlying is greater than or equal to its Initial Level during the term of the Notes other than on a Call Observation Date but then drops on a Call Observation Date to a level that is less than its Initial Level, the Notes will not be automatically called. Further, if the Notes are not called, even if the level of the Least Performing Underlying is greater than or equal to its Buffer Level during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a level that is less than the Buffer Level, the Payment at Maturity will be less, possibly significantly less, than it would have been had the Payment at Maturity been linked to the level of the Least Performing Underlying prior to such decrease. Although the actual levels of the Underlyings on the Maturity Date or at other times during the term of the Notes may be higher than their respective levels on the Call Observation Dates, whether the Notes will be called and the Payment at Maturity will be based solely on the Official Closing Level of the Underlyings on the Call Observation Dates.

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 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.

Small-capitalization risk. 

The RTY tracks companies that are considered small-capitalization. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the level of the RTY may be more volatile than an investment in stocks issued by large-capitalization companies. Stock prices of small-capitalization companies may also be more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded, making it difficult for the RTY to track them. In addition, small-capitalization companies are often less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. These companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

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.

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 Official Closing Level of either Underlying on any Call Observation Date or the Final Valuation Date. 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 Underlyings or return on the Notes.

The table below illustrates the Payment at Maturity on a $1,000 investment in the Notes for a hypothetical range of Final Returns of the Least Performing Underlying from 0% (the Notes will be automatically called if the Final Return of Least Performing Underlying is greater than or equal to 0%) to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Notes” as used below is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 Principal Amount to $1,000. You should consider carefully whether the Notes are suitable to your investment goals. The numbers appearing in the following table and examples have been rounded for ease of analysis. The following table and examples assume the following:

}	Principal Amount:	$1,000
}	Hypothetical Initial Level:	1,000 for the RTY and SPX
}	Buffer Level:	with respect to each Underlying, 80% of its Initial Value
}	Rebate Return:	10.50%
}	Downside Leverage Factor:	1.25
}	Call Premiums and Call Prices on the Call Observation Dates:

Call Observation Dates	Call Prices	Call Premiums
June 15, 2016	$1,047.50	4.75%
December 14, 2016	$1,095.00	9.50%
June 14, 2017 (Final Valuation Date)	$1,142.50	14.25%

Hypothetical Final Return of the Least Performing Underlying	Hypothetical Payment at Maturity	Hypothetical Return on the Notes

Notes Are Called on a Call Observation Date

The Notes are called because the Official Closing Level of each Underlying is at or above its Initial Value on one of the three Call Observation Dates, and you will receive the applicable Call Price.

Example 1—The Official Closing Level of each Underlying on the first Call Observation Date is greater than or equal to its Initial Level.

Because the Official Closing Level of each Underlying on the first Call Observation Date (expected to be June 15, 2016) is at or above its Initial Level, the Notes are automatically called at the applicable Call Price of $1,047.50 per Note, representing a 4.75% return on the Notes.

Example 2— The Official Closing Level of each Underlying on the second Call Observation Date is greater than or equal to its Initial Level.

Because (i) the Official Closing Level of one Underlying on the first Call Observation Date is below its Initial Level and (ii) the Official Closing Level of each Underlying on the second Call Observation Date (expected to be December 13, 2016) is above its Initial Level, the Notes are not called on the first Call Observation Date but are automatically called on the second Call Observation Date at the applicable Call Price of $1,095 per Note, representing a 9.50% return on the Notes.

Example 3— The Official Closing Level of each Underlying on the final Call Observation Date is greater than or equal to its Initial Level.

Because (i) the Official Closing Level of at least one Underlying on the first two Call Observation Dates are below its Initial Level and (ii) the Official Closing Level of each Underlying on the final Call Observation Date (which is also the Final Valuation Date) is above its Initial Level, the Notes are not called on the first two Call Observation Dates but are automatically called on the final Call Observation Date at the applicable Call Price of $1,142.50 per Note, representing a 14.25% return on the Notes.

Notes Are Not Called on any Call Observation Date

The Notes are not automatically called because the Official Closing Level of at least one Underlying is below its Initial Level on each Call Observation Date. Since the Notes are not called, the Payment at Maturity will be based on the Final Return of the Least Performing Underlying.

Example 4— The Final Level of the Least Performing Underlying is greater than or equal to its Buffer Level.

Because the Final Level of the Least Performing Underlying is greater than or equal to its Buffer Level, you will receive $1,105 per $1,000 in Principal Amount, calculated as follows:

Payment at Maturity = $1,000 + ($1,000 × 10.50%) = $1,105

Example 5— The Final Level of the Least Performing Underlying is less than its Buffer Level.

Because the Final Level of the Least Performing Underlying is less than its Buffer Level, you will receive $750.00 per $1,000 in Principal Amount, calculated as follows:

Payment at Maturity = $1,000 + [$1,000 × (-40.00% + 20%) × 1.25] = $750.00

In this example, you would lose some or all of your Principal Amount at maturity.

If the Notes are not called and the Final Level of the Least Performing Underlying is less than its Buffer Level, you will be exposed to any decrease in the level of the Least Performing Underlying beyond -20% on a 1.25:1 basis and could lose up to 100% of your principal at maturity.

EVENTS OF DEFAULT AND ACCELERATION

If the Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Notes, the calculation agent will determine the accelerated payment due and payable in the same general manner as described in this free writing prospectus except that in such a case, the scheduled trading day immediately preceding the date of acceleration will be used as the final Call Observation Date and the Final Valuation Date. If the Notes are called, the calculation agent will determine the applicable Call Price based upon the Call Premiums and the amount of time that the Notes have been outstanding through the date of acceleration. If a market disruption event exists with respect to an Underlying on that scheduled trading day, then the accelerated Final Valuation Date 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 following the postponed accelerated Final Valuation Date. For the avoidance of doubt, if no market disruption event exists with respect to an Underlying on the scheduled trading day preceding the date of acceleration, the determination of such Underlying’s Final Level will be made on such date, irrespective of the existence of a market disruption event with respect to the other Underlying occurring on such date.

If the Notes have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the Notes. 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 Notes.

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 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, Morrison & Foerster LLP, it is reasonable to treat a Note 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 Notes prior to their maturity or an earlier sale, call or exchange. Any such gain or loss recognized should be long-term capital gain or loss provided you have held the Note for more than one year upon maturity, sale, call or exchange, and should be short-term capital gain or loss otherwise. The deductibility of capital losses by U.S. holders (as defined under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement) is subject to limitations.

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 Notes 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 Notes.

Recently finalized Treasury Regulations provide that withholding on “dividend equivalent” payments (as discussed in the accompanying prospectus supplement), if any, will not apply to Notes 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 or redemption of the Notes will only apply to payments made after December 31, 2018.

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.
