The Notes

The Notes may be suitable for investors who believe that the level of the Reference Asset will not decrease significantly over the term of the Notes. If the Official Closing Level of the Reference Asset on any Observation Date is greater than or equal to the Coupon Trigger, you will receive the Contingent Coupon with respect to that Observation Date and any previously unpaid Contingent Coupons with respect to the prior Observation Dates on the applicable Coupon Payment Date.

If the Official Closing Level of the Reference Asset is at or above the Call Level on any Observation Date, your Notes will be automatically called and you will receive a payment equal to 100% of the Principal Amount, together with the Contingent Coupon with respect to that Observation Date and any previously unpaid Contingent Coupons with respect to the prior Observation Dates on the corresponding Call Payment Date.

If the Notes are not automatically called and the Final Level is greater than or equal to the Barrier Level, you will receive a Payment at Maturity equal to the Principal Amount. You will also receive the final Contingent Coupon and any previously unpaid Contingent Coupons with respect to the prior Observation Dates if the Final Level is greater than or equal to the Coupon Trigger.

If the Notes are not automatically called and the Final Level is less than the Barrier Level, you will lose 1% of your principal for every 1% decline in the level of the Reference Asset. Even with any Contingent Coupons, your return on the Notes may be negative.

The offering period for the Notes is through March 20, 2017

 

FWP-2

Illustration of Payment Scenarios

Your payment on the Notes will depend on whether the Notes have been automatically called, whether the Official Closing Level of the Reference Asset on an Observation Date is greater than or equal to the Coupon Trigger, and whether the Final Level is greater than or equal to the Barrier Level. If your Notes are not automatically called, you will lose some or all of your Principal Amount at maturity if the Final Level is less than the Barrier Level. Even with any Contingent Coupons, your return on the Notes may be negative.

PAYMENT ON THE NOTES

Call Feature

The Notes will be automatically called if the Official Closing Level of the Reference Asset is at or above the Call Level on any Observation Date. If the Notes are automatically called, investors will receive on the corresponding Call Payment Date, a cash payment per $1,000 in Principal Amount equal to 100% of the Principal Amount, together with the Contingent Coupon with respect to that Observation Date and any previously unpaid Contingent Coupons with respect to the prior Observation Dates.

Contingent Coupon

We will pay an annual Contingent Coupon payment on a Coupon Payment Date if the Official Closing Level of the Reference Asset on the applicable Observation Date is greater than or equal to the Coupon Trigger. Otherwise, no coupon will be paid on such Coupon Payment Date. However, if a Contingent Coupon is not payable for an Observation Date because the Official Closing Level of the Reference Asset on that Observation Date is less than the Coupon Trigger, such Contingent Coupon will be payable on a later Coupon Payment Date if the Official Closing Level or the Final Level, as applicable, is greater than or equal to the Coupon Trigger on such later Observation Date. For the avoidance of doubt, once a previous Contingent Coupon has been paid on a later Coupon Payment Date, it will not be paid again on any subsequent Coupon Payment Date.

For information regarding the record dates applicable to the Contingent Coupons payable on the Notes, please see the section entitled “Recipients of Interest Payments” on page S-12 in the accompanying prospectus supplement. The Contingent Coupon Rate will be at least 7.55% per annum (at least $75.50 per $1,000 in Principal Amount per annual payment, if payable) (to be determined on the Pricing Date).

Maturity

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

n If the Final Return is greater than or equal to -40%:

$1,000

In addition, you will receive the final Contingent Coupon and any previously unpaid Contingent Coupons with respect to the prior Observation Dates if the Final Return is greater than or equal to -20%

n If the Final Return is less than -40%:

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

If the Final Level of the Reference Asset is less than the Barrier Level, you will lose at least 40% of the Principal Amount, and your Payment at Maturity could be zero.

Calculation Agent

We or one of our affiliates will act as calculation agent with respect to the Notes.

Reference Sponsor

STOXX Limited is the reference sponsor.

FWP-7

INVESTOR SUITABILITY

The Notes may be suitable for you if:

4 You believe that the Official Closing Level of the Reference Asset will be at or above the Coupon Trigger on most Observation Dates, especially during the later term of the Notes, and the Final Level of the Reference Asset will be at or above the Barrier Level.

4 You seek an annual Contingent Coupon based on the performance of the Reference Asset, which, and any previously unpaid Contingent Coupons, will be paid at the Contingent Coupon Rate if the Official Closing Level of the Reference Asset is greater than or equal to the Coupon Trigger on any Observation Date.

4 You are willing to accept that the return on the Notes will be limited to the Contingent Coupons, if any, and do not seek an investment that provides an opportunity to participate in the appreciation of the Reference Asset.

4 You would be willing to invest in the Notes based on the Contingent Coupon Rate set forth above (the actual Contingent Coupon Rate will be set on the Pricing Date).

4 You are willing to make an investment that is exposed to the potential full downside performance of the Reference Asset on a 1-to-1 basis if the Notes are not called and the Final Return is less than -40%.

4 You are willing to hold the Notes that will be automatically called on any Observation Date on which the Official Closing Level of the Reference Asset is at or above the Call Level, or you are otherwise willing to hold the Notes to maturity.

4 You are willing to forgo guaranteed interest payments on the Notes, and dividends or other distributions paid on the securities included in the Reference Asset.

4 You do not seek an investment for which there will be an active secondary market.

4 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.

4 You are comfortable with the creditworthiness of HSBC, as Issuer of the Notes.

The Notes may not be suitable for you if:

4 You believe that the Official Closing Level of the Reference Asset will be below the Coupon Trigger on most Observation Dates, and the Final Level of the Reference Asset will be below the Barrier Level.

4 You believe that the Contingent Coupons, if any, will not provide you with your desired return.

4 You are unwilling to accept that the return on the Notes will be limited to the Contingent Coupons, if any, or you seek an investment that provides an opportunity to participate in the appreciation of the Reference Asset.

4 You would not be willing to invest in the Notes based on the Contingent Coupon Rate set forth above (the actual Contingent Coupon Rate will be set on the Pricing Date).

4 You are unwilling to make an investment that is exposed to the potential full downside performance of the Reference Asset on a 1-to-1 basis if the Final Return is less than -40%.

4 You are unable or unwilling to hold the Notes that will be automatically called on any Observation Date on which the Official Closing Level of the Reference Asset is at or above the Call Level, or you are otherwise unable or unwilling to hold the Notes to maturity.

4 You prefer to receive guaranteed periodic interest payments on the Notes, or the dividends or other distributions paid on the securities included in the Reference Asset.

4 You seek an investment for which there will be an active secondary market.

4 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.

4 You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Notes.

FWP-8

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 in the accompanying prospectus supplement and beginning on page S-2 of the accompanying Equity Index Underlying Supplement. Investing in the Notes is not equivalent to investing directly in the securities included in the Reference Asset. You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this free writing prospectus and the accompanying 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:

4 “—Risks Relating to All Note Issuances” in the prospectus supplement;

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

4 “—Securities Prices Generally Are Subject to Political, Economic, Financial and Social Factors that Apply to the Markets in which They Trade and, to a Lesser Extent, Foreign Markets” in the Equity Index Underlying Supplement; and

4 “—Time Differences Between the Domestic and Foreign Markets and New York City May Create Discrepancies in the Trading Level or Price of the Notes” 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 if the Notes are not automatically called and the Final Level of the Reference Asset is less than the Barrier Level, you will lose 1% of the Principal Amount for each 1% that the Final Return is less than 0%. In such a case, you will lose at least 40% of your principal, and your Payment at Maturity could be zero. Even with any Contingent Coupons, your return on the Notes may be negative.

You may not receive any Contingent Coupons.

We will not necessarily make periodic coupon payments on the Notes. If the Official Closing Level of the Reference Asset on an Observation Date is less than the Coupon Trigger, we will not pay you the Contingent Coupon applicable to that Observation Date on the relevant Coupon Payment Date. Although any previously unpaid Contingent Coupons with respect to previous Observation Dates will become payable on a subsequent Observation Date if the Official Closing Level of the Reference Asset on that day is greater than or equal to the Coupon Trigger, if the Official Closing Level of the Reference Asset on each of the Observation Dates is less than the Coupon Trigger, we will not pay you any Contingent Coupons during the term of, and you will not receive a positive return on, the Notes. Generally, this non-payment of the Contingent Coupon coincides with a period of greater risk of principal loss on the Notes.

Your return on the notes is limited to the Contingent Coupons, if any, regardless of any appreciation in the level of the Reference Asset.

For each $1,000 in Principal Amount, you will receive $1,000 at maturity plus the final Contingent Coupon if the Final Level of the Reference Asset is equal to or greater than the Barrier Level, regardless of any appreciation in the level of the Reference Asset, which may be significant. Accordingly, the return on the Notes may be significantly less than the return on a direct investment in the securities included in the Reference Asset during the term of the Notes.

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

If the Notes are automatically called early, the holding period over which you may receive Contingent Coupons could be as little as 12 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.

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 Contingent Coupon and 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.

FWP-9

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 prices 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 Reference Asset 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 16 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 level of the Reference Asset at any time other than the Observation Dates, including the Final Valuation Date.

The payments on the Notes will be based on the Official Closing Levels of the Reference Asset on the Observation Dates, including the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the level of the Reference Asset is greater than or equal to the Coupon Trigger during the term of the Notes other than on an Observation Date but then decreases on that Observation Date to a level that is less than the Coupon Trigger, the Contingent Coupon will not be payable for that Observation Date. Similarly, if the Notes are not called, even if the level of the Reference Asset is greater than or equal to the Barrier 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 Barrier 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 Reference Asset prior to such decrease. Although the actual levels of the Reference Asset on the Maturity Date or at other times during the term of the Notes may be higher than the levels on the Observation Dates, whether each Contingent Coupon will be payable and the Payment at Maturity will be based solely on the Official Closing Levels of the Reference Asset on the applicable Observation Dates.

FWP-10

Higher Contingent Coupon Rates or lower Barrier Levels are generally associated with Reference Assets with greater expected volatility and therefore can indicate a greater risk of loss.

"Volatility" refers to the frequency and magnitude of changes in the level of a Reference Asset. The greater the expected volatility with respect to a Reference Asset on the Pricing Date, the higher the expectation as of the Pricing Date that the level of that Reference Asset could close below its Barrier Level on the Final Valuation Date, indicating a higher expected risk of loss on the Notes. This greater expected risk will generally be reflected in a higher Contingent Coupon Rate than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as a lower Barrier Level or a lower Coupon Trigger) than for similar securities linked to the performance of the Reference Asset with a lower expected volatility as of the Pricing Date. You should therefore understand that a relatively higher Contingent Coupon Rate may indicate an increased risk of loss. Further, a relatively lower Barrier Level may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of a Reference Asset can change significantly over the term of the Notes. The level of the Reference Asset could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Reference Asset and the potential to lose some or all of your principal at maturity.

Risks associated with non-U.S. companies.

The level of the Reference Asset depends upon the stocks of companies located within the Eurozone, and thus involves risks associated with the home countries of those non-U.S. companies, some of which are and have been experiencing economic stress. The prices of these non-U.S. stocks may be affected by political, economic, financial and social factors in the home country of each applicable company, including changes in that country’s government, economic and fiscal policies, currency exchange laws or other laws or restrictions, which could affect the value of the Notes. These foreign securities may have less liquidity and could be more volatile than many of the securities traded in U.S. or other securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may affect trading levels or prices and volumes in those markets. The other special risks associated with foreign securities may include, but are not limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; different accounting and disclosure standards; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of the Reference Asset and, as a result, the value of the Notes.

The Notes will not be adjusted for changes in exchange rates.

Although the equity securities that comprise the Reference Asset are traded in euro, and your Notes are denominated in U.S. dollars, the amount payable on your Notes, if any, will not be adjusted for changes in the exchange rates between the U.S. dollar and the euro. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the level of the Reference Asset, and therefore the value of your Notes. The amount we pay in respect of your Notes, if any, will be determined solely in accordance with the procedures described in this free writing prospectus.

Changes that affect the Reference Asset may affect the market value of the Notes and the amount you will receive on the Notes.

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 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 market 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 payments due on the Notes.

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.

FWP-11

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.

Uncertain tax treatment.

For a discussion of the U.S. federal income tax consequences of your investment in the Notes, 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 the Initial Level. We cannot predict the Official Closing Level of the Reference Asset on any Observation Date, including 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 Reference Asset or return on the Notes.

The table and examples below illustrate how the Contingent Coupon and the Payment at Maturity would be calculated with respect to a $1,000 investment in the Notes, given a range of hypothetical Reference Asset performances. The hypothetical returns on the Notes below are numbers, expressed as percentages, that result 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:

4	Principal Amount:	$1,000
4	Hypothetical Initial Level:	3,000*
4	Hypothetical Call Level:	3,150, 105% of the Initial Level
4	Hypothetical Barrier Level:	1,800, 60% of the Initial Level
4	Hypothetical Coupon Trigger:	2,400, 80% of the Initial Level
4	Hypothetical Contingent Coupon Rate:	7.55% per annum. The actual Contingent Coupon Rate will be at least 7.55% per annum (to be determined on the Pricing Date). If the Official Closing Level of the Reference Asset on each Observation Date or the Final Valuation Date is greater than or equal to the Coupon Trigger, the Contingent Coupons payable over the term of the Notes would total $528.50 per $1,000 in Principal Amount.

* The hypothetical Initial Level of 3,000 used in the examples below has been chosen for illustrative purposes only and does not represent the actual Initial Level. The actual Initial Level of the Reference Asset will be set forth in the final pricing supplement to which this free writing prospectus relates.

Summary of the Examples

	Notes Are Called on an Observation Date	Notes Are Not Called on Any Observation Date
	Example 1	Example 2	Example 3
Initial Level	3,000	3,000	3,000
Call Level	3,150	3,150	3,150
Barrier Level	1,800	1,800	1,800
Coupon Trigger	2,400	2,400	2,400
Official Closing Level / Percentage Change on the First Observation Date	2,550/-15%	2,250/-25%	2,100/-30%
Official Closing Level / Percentage Change on the Second Observation Date	3,150/5%	2,550/-15%	1,950/-35%
Official Closing Levels / Percentage Changes on the Third Through the Sixth Observation Dates	N/A	Various (all below 2,400 /-20%)	Various (all below 2,400 /-20%)
Official Closing Levels / Percentage Changes on the Final Valuation Date	N/A	2,400/-20%	1,500/-50%
Contingent Coupons Paid Prior to Call or Maturity	1 x $75.50 = $75.50	1 x $75.50 = $75.50	0 x $75.50 = $0.00
Payment upon an Automatic Call	$1,000 + (1 x $75.50) = $1,075.50	N/A	N/A
Payment at Maturity	N/A	$1,000 + (6 x $75.50) = $1,453.00	$1,000 + ($1,000 x -50%) = $500.00
Total Return on the Notes	15.10%	52.85%	-50.00%

FWP-13

Example 1—The Official Closing Level of the Reference Asset on the second Observation Date is greater than or equal to the Call Level and the Reference Asset closed at or above the Coupon Trigger on the prior Observation Date.

Because the Official Closing Level of the Reference Asset on the second Observation Date is at or above the Call Level, the Notes will be called and you will receive $1,075.50 per Note, reflecting the Principal Amount plus the applicable Contingent Coupon. When added to the Contingent Coupon payment of $75.50 received in respect of the prior Observation Date, we will have paid you a total of $1,151.00 per Note, resulting in a total return of 15.10% on the Notes.

Example 2— The Notes are not called, the Final Level of the Reference Asset is greater than or equal to the Barrier Level and the Coupon Trigger, and the Reference Asset closed at or above the Coupon Trigger on the second Observation Date.

Because the Final Level of the Reference Asset is greater than or equal to the Barrier Level and the Coupon Trigger, you will receive $1,000 per $1,000 in Principal Amount plus the final Contingent Coupon and any previously unpaid Contingent Coupons with respect to the prior Observation Dates, calculated as follows:

Payment at Maturity = $1,000 + (6 x $75.50) = $1,453.00

When added to the Contingent Coupon payment of $75.50 received in respect of the second Observation Date, we will have paid you a total of $1,528.50 per Note, resulting in a total return of 52.85% on the Notes.

Example 3— The Notes are not called, the Final Level of the Reference Asset is less than the Barrier Level, and the Reference Asset did not close at or above the Coupon Trigger on any Observation Date.

Because the Final Level of the Reference Asset is less than the Barrier Level, you will receive $500 per $1,000 in Principal Amount, calculated as follows:

Payment at Maturity = $1,000 + ($1,000 x -50%) = $500.00

Because there was no Contingent Coupon payable in respect of the prior Observation Dates, we will pay you a total of $500.00, resulting in a -50.00% return on the Notes.

If the Notes are not called and the Final Level of the Reference Asset is less than the Barrier Level, you will be exposed to any decrease in the level of the Reference Asset on a 1:1 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 Observation Date and the 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 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.

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)

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the Notes 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 Notes directly to investors. HSBC Securities (USA) Inc. proposes to offer the Notes 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 2.25% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers.

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.

FWP-16

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 contingent income-bearing 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 contingent income-bearing pre-paid executory contract with respect to the Reference Asset. Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes, other characterizations and treatments are possible and the timing and character of income in respect of the Notes might differ from the treatment described herein. For example, the Notes could be treated as debt instruments that are “contingent payment debt instruments” for U.S. federal income tax purposes subject to the treatment described under the heading “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 — Contingent Notes” in the accompanying prospectus supplement.

We will not attempt to ascertain whether any of the entities whose stock is included in the Reference Asset 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 the Reference Asset 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 the Reference Asset and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Reference Asset is or becomes a PFIC or a USRPHC.

U.S. Holders. Please see the discussion under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated as Executory Contracts” in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to U.S. holders (as defined in the accompanying prospectus supplement). Pursuant to the approach discussed above, we intend to treat any gain or loss upon maturity or an earlier sale or call as capital gain or loss in an amount equal to the difference between the amount you receive at such time (other than with respect to a Contingent Coupon) and your tax basis in the Note. Any such gain or loss will be long-term capital gain or loss if you have held the Note for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a Note generally will equal your cost of the Note. In addition, the tax treatment of the Contingent Coupons is unclear. Although the tax treatment of the Contingent Coupons is unclear, we intend to treat any Contingent Coupon, including on the Maturity Date, as ordinary income includible in income by you at the time it accrues or is received in accordance with your normal method of accounting for U.S. federal income tax purposes.

Non-U.S. Holders. Please see the discussion under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of Non-U.S. Holders” in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to non-U.S. holders (as defined in the accompanying prospectus supplement). Because the U.S. federal income tax treatment (including the applicability of withholding) of the Contingent Coupons is uncertain, the entire amount of the Contingent Coupons will be subject to U.S. federal income tax withholding at a 30% rate (or at a lower rate under an applicable income tax treaty). We will not pay any additional amounts in respect of such withholding.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, the IRS has issued guidance that states that the U.S. Treasury Department and the IRS intend to amend the effective dates of the U.S. Treasury regulations to provide that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2018. Based on the Issuer’s determination that the Notes are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Asset or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the Reference Asset or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

FWP-17

Foreign Account Tax Compliance Act. The Internal Revenue Service 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 Notes 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 Note, please see the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

PROSPECTIVE PURCHASERS OF NOTES 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.
