ADDITIONAL TERMS OF THE SECURITIES

Payment at Maturity

On the Maturity Date, for each security you hold, we will pay you the Payment at Maturity, 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, equal to the lesser of:

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

(b) $1,000 + ($1,000 × Maximum Cap)

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

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

$1,000 + [$1,000 × (Reference Return + 15.00%)]

Under these circumstances, you will lose 1% of the Principal Amount for each percentage point that the Reference Return is below the Buffer Value. For example, if the Reference Return is -30%, you will suffer a 15.00% loss and receive 85.00% of the Principal Amount, subject to the credit risk of HSBC. If the Reference Return is less than the Buffer Value, you will lose some or a significant portion (up to 85.00%) of the Principal Amount.

Interest

The securities will not pay interest.

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

Reference Sponsor

FTSE Russell is the Reference Sponsor.

Market Disruption Event

The provisions of this section supersede and replace the definition of “Market Disruption Event” set forth beginning on page S-57 of the accompanying Equity Index Underlying Supplement.

A “Market Disruption Event” means, with respect to the Reference Asset, any of the following events as determined by the calculation agent in its sole discretion:

(A) The occurrence or existence of a material suspension of or limitation imposed on trading by the Relevant Stock Exchanges or otherwise relating to securities which then comprise 20% or more of the level of the Reference Asset or any Successor Index (as defined in the accompanying Equity Index Underlying Supplement) at any time during the one-hour period that ends at the Close of Trading on that day, whether by reason of movements in price exceeding limits permitted by those Relevant Stock Exchanges or otherwise.

(B) The occurrence or existence of a material suspension of or limitation imposed on trading by any Related Futures or Options Exchange or otherwise in futures or options contracts relating to the Reference Asset or any Successor Index on any Related Futures or Options Exchange at any time during the one-hour period that ends at the Close of Trading on that day, whether by reason of movements in price exceeding limits permitted by the Related Futures or Options Exchange or otherwise.

(C) The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market values for, securities that then comprise 20% or more of the level of the Reference Asset or any Successor Index on their Relevant Stock Exchanges at any time during the one-hour period that ends at the Close of Trading on that day.

(D) The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market values for, futures or options contracts relating to the Reference Asset or any Successor Index on any Related Futures or Options Exchange at any time during the one-hour period that ends at the Close of Trading on that day.

(E) The closure on any Exchange Business Day of the Relevant Stock Exchanges on which securities that then comprise 20% or more of the level of the Reference Asset or any Successor Index are traded or any Related Futures or Options Exchange prior to its Scheduled Closing Time unless the earlier closing time is announced by the Relevant Stock Exchange or Related Futures or Options Exchange, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on such Relevant Stock Exchange or Related Futures or Options Exchange, as applicable, and (2) the submission

FWP-5

deadline for orders to be entered into the Relevant Stock Exchange or Related Futures or Options Exchange, as applicable, system for execution at such actual closing time on that day.

(F) The Relevant Stock Exchange for any security underlying the Reference Asset or the Successor Index or any Related Futures or Options Exchange fails to open for trading during its regular trading session.

For purposes of determining whether a Market Disruption Event has occurred:

(1) the relevant percentage contribution of a security to the level of the Reference Asset or any Successor Index will be based on a comparison of (x) the portion of the level of the Reference Asset attributable to that security and (y) the overall level of the Reference Asset or the Successor Index, in each case immediately before the occurrence of the Market Disruption Event;

(2) the “Close of Trading” on any Scheduled Trading Day for the Reference Asset or any Successor Index means the Scheduled Closing Time of the Relevant Stock Exchanges with respect to the securities underlying the Reference Asset or the Successor Index on such Scheduled Trading Day; provided that, if the actual closing time of the regular trading session of any such Relevant Stock Exchange is earlier than its Scheduled Closing Time on such Scheduled Trading Day, then (x) for purposes of clauses (A) and (C) of the definition of “Market Disruption Event” above, with respect to any security underlying the Reference Asset or the Successor Index for which such Relevant Stock Exchange is its Relevant Stock Exchange, the “Close of Trading” means such actual closing time and (y) for purposes of clauses (B) and (D) of the definition of “Market Disruption Event” above, with respect to any futures or options contract relating to the Reference Asset or the Successor Index, the “Close of Trading” means the latest actual closing time of the regular trading session of any of the Relevant Stock Exchanges, but in no event later than the Scheduled Closing Time of the Relevant Stock Exchanges;

(3) the “Scheduled Closing Time” of any Relevant Stock Exchange or Related Futures or Options Exchange on any Scheduled Trading Day for the Reference Asset or any Successor Index means the scheduled weekday closing time of such Relevant Stock Exchange or Related Futures or Options Exchange on such Scheduled Trading Day, without regard to after hours or any other trading outside the regular trading session hours; and

(4) an “Exchange Business Day” means any Scheduled Trading Day for the Reference Asset or any Successor Index on which each Relevant Stock Exchange for the securities underlying the Reference Asset or any Successor Index and each Related Futures or Options Exchange are open for trading during their respective regular trading sessions, notwithstanding any such Relevant Stock Exchange or Related Futures or Options Exchange closing prior to its Scheduled Closing Time.

A “Scheduled Trading Day” means a day, as determined by the calculation agent, on which (i) the Relevant Stock Exchanges with respect to each security underlying the Reference Asset are scheduled to be open for trading for their respective regular trading sessions and (ii) each Related Futures or Options Exchange is scheduled to be open for trading for its regular trading session.

A “Related Futures or Options Exchange” for the Reference Asset means an exchange or quotation system where trading has a material effect (as determined by the calculation agent) on the overall market for futures or options contracts relating to the Reference Asset.

The “Relevant Stock Exchange” for any security underlying the Reference Asset means the primary exchange or quotation system on which such security is traded, as determined by the calculation agent.

Postponement of the Final Valuation Date and the Maturity Date

The provisions of this section supersede and replace the section entitled “Additional Terms of the Notes—Valuation Dates” on page S-59 of the accompanying Equity Index Underlying Supplement.

If the scheduled Final Valuation Date is not a Scheduled Trading Day or a Market Disruption Event occurs or is continuing with respect to the Reference Asset on that day, then the Final Valuation Date will be postponed to the first succeeding Scheduled Trading Day on which a Market Disruption Event has not occurred and is not continuing; however, if such first succeeding Scheduled Trading Day has not occurred as of the eighth Scheduled Trading Day after the originally scheduled Final Valuation Date, that eighth Scheduled Trading Day shall be deemed to be the Final Valuation Date, and the calculation agent will determine the Official Closing Level of the Reference Asset on such eighth Scheduled Trading Day in accordance with the formula for and method of calculating the Official Closing Level of the Reference Asset last in effect prior to commencement of the Market Disruption Event, using the Closing Price (or, with respect to any relevant security, if a Market Disruption Event has occurred with respect to such security, its good faith estimate of the value of such security at the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange. As used herein, “Closing Price” means, with respect to any security on any date, the Relevant Stock Exchange traded or quoted price of such security as of the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange. If the Final Valuation Date is postponed, then the maturity date will also be postponed by the same number of business days and no interest will be paid in respect of such postponement.

Trustee Conflict of Interest

Wells Fargo Securities, one of the agents, is an affiliate of the trustee under the Senior Indenture and is acting as an underwriter for this offering. Therefore, if a default occurs with respect to the securities within one year after this offering (or any other offering of our securities in which an affiliate of the trustee participates as an underwriter), the trustee would likely be considered to have a conflicting

FWP-6

interest for purposes of the Trust Indenture Act of 1939. In that event, except in very limited circumstances, the trustee would be required to resign as trustee under the Senior Indenture and we would be required to appoint a successor trustee, unless the default is cured or waived within 90 days. If the trustee resigns following a default or for any other reason, it may be difficult to identify and appoint a qualified successor trustee. The trustee will remain the trustee under the Senior Indenture until a successor is appointed. During the period of time until a successor is appointed, the trustee will have both (a) duties to noteholders under the Senior Indenture and (b) a conflicting interest under the Senior Indenture for purposes of the Trust Indenture Act.

INVESTOR SUITABILITY

The securities may be suitable for you if:

The securities may not be suitable for you if:

4  You seek an investment with an enhanced return linked to the potential positive performance of the Reference Asset and you believe that the level of the Reference Asset will increase moderately over the term of the securities. 4  You are willing to invest in the securities based on the Maximum Cap range indicated herein, which may limit your return at maturity. The actual Maximum Cap will be determined on the Pricing Date. 4  You are willing to make an investment that is exposed to any negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is less than the Buffer Value. 4  You are willing to forgo dividends or other distributions paid to holders of the securities included in the Reference Asset. 4  You understand and accept the risks associated with the Reference Asset. 4  You are willing to accept the risk and return profile of the securities versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating. 4  You do not seek current income from your investment. 4  You do not seek an investment for which there is an active secondary market. 4  You are willing to hold the securities to maturity. 4  You are comfortable with the creditworthiness of HSBC, as issuer of the securities.

4  You believe that the Reference Return will be negative or that the Reference Return will not be sufficiently positive to provide you with your desired return. 4  You are unwilling to invest in the securities based on the Maximum Cap range indicated herein, which may limit your return at maturity. The actual Maximum Cap will be determined on the Pricing Date. 4  You are unwilling to make an investment that is exposed to any negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is less than the Buffer Value. 4  You seek an investment that provides full return of principal. 4  You do not understand or accept the risks associated with the Reference Asset. 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 prefer to receive dividends or other distributions paid to holders of the securities included in the Reference Asset. 4  You seek current income from your investment. 4  You seek an investment for which there will be an active secondary market. 4  You are unable or unwilling to hold the securities to maturity. 4  You are not willing or are unable to assume the credit risk associated with HSBC, as issuer of the securities.

FWP-7

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 in the accompanying prospectus supplement and on page S-2 of the accompanying Equity Index Underlying Supplement. Investing in the securities is not equivalent to investing directly in the Reference Asset or any of the stocks comprising the Underlying Index. 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:

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

4“— 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.

You will be exposed to any decrease in the level of the Reference Asset by more than 15.00% on a 1:1 basis. Accordingly, if the Reference Return is less than the Buffer Value, your Payment at Maturity will be less than the Principal Amount by an amount proportionate to any decrease in the level of the Reference Asset by more than 15.00%. You may lose up to 85.00% of the Principal Amount at maturity.

The return on the securities will be limited by the Maximum Cap and may be lower than the return on conventional debt securities or a direct investment in the Reference Asset.

Even if the Final Level is greater than the Initial Level, the amount you receive at maturity may only be slightly greater than the Principal Amount, and your return on the securities may be less than the return you would earn if you bought a conventional fixed-rate or floating-rate debt security of HSBC or another issuer with a similar credit rating with the same maturity date.

In addition, the opportunity to participate in the possible increases in the level of the Reference Asset through an investment in the securities will be limited, because the return on the securities will not exceed the Maximum Cap. Furthermore, the Upside Participation Rate will have no additional positive impact on your return for any Final Level exceeding the Final Level at which the Maximum Cap is reached. Therefore, the return on the securities may be lower than the return on a direct investment in the Reference Asset.

The Reference Return 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 Reference Return 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. You will have no ability to pursue any securities included in the Reference Asset for payment. 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, and you could lose some or all of your investment.

The securities will not bear interest.

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

FWP-8

Changes that affect the Reference Asset may affect the level of the Reference Asset and 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 level of the Reference Asset and the value of 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.

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 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 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 may be less than the price to public.

The price to public takes into account certain costs. These costs, which, except for the underwriting discount, 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 an agent 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 an agent may initially buy or sell the securities in the secondary market, if any, and the value used for customer account statements, if any, 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 its discretion, an agent may elect to effectively reimburse to investors a portion of the estimated hedging cost and other costs in connection with the securities that will no longer be incurred over the term of the securities. This discretionary election will be made, and the temporary reimbursement period will be determined, 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 the estimated costs which may be effectively reimbursed to investors in this way may not be allocated ratably throughout the reimbursement period, and such reimbursement may be discontinued at any time, or the duration of the reimbursement period may be shortened after the Original Issue Date of the securities based on changes in market conditions and other factors that cannot be predicted.

FWP-9

The securities lack liquidity.

The securities will not be listed on any securities exchange. The agents are 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 the agents are 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, determining the Estimated Initial Value 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. See “—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” above, “Risk Factors—General risks related to Indices—Our or our affiliates business activities relating to the stocks or securities tracked by an equity index may create conflicts of interest with you” in the Equity Index Underlying Supplement and “Risk Factors—Risks Relating to all Note Issuances— Trading and other transactions by us or our affiliates could affect the trading level or price and/or level of the Reference Asset, the trading value of the notes or the amount you may receive at maturity” and “—Research reports and other transactions may create conflicts of interest between you and us” and “—Our trading, hedging and other business activities, and those of the agents, may create conflicts of interest with you” in the prospectus supplement.

Historical levels of the Reference Asset should not be taken as an indication of its future performance during the term of the securities.

The level of the Reference Asset will determine the Payment at Maturity. It is impossible to predict whether the Final Level of the Reference Asset will fall or rise compared to the Initial Level. The level of the Reference Asset will be influenced by complex and interrelated political, economic, financial and other factors that can affect the markets in which the securities included in the Reference Asset are traded and the prices of those securities. Accordingly, any historical levels of the Reference Asset should not be taken as an indication of its future performance.

The securities are subject to small-capitalization risk. 

The Reference Asset tracks companies that are considered small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the level of the Reference Asset 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 Reference Asset 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.

The amount you will receive on the securities will depend upon the performance of the Reference Asset. Therefore, the securities are subject to the following risks, as set forth in the accompanying prospectus supplement or the Equity Index Underlying Supplement:

· You must rely on your own evaluation of the merits of an investment in the notes;

· The price at which you will be able to sell your notes prior to maturity will depend on a number of factors, and may be substantially less than the amount you had originally invested;

· The notes are not insured against loss by any third parties; you can depend only on our earnings and assets for payment and interest, if any, on the notes;

· Trading and other transactions by us or our affiliates could affect the trading level or price and/or level of the Reference Asset, the trading value of the notes or the amount you may receive at maturity;

· Research reports and other transactions may create conflicts of interest between you and us;

· Our trading, hedging and other business activities, and those of the agents, may create conflicts of interest with you;

· Equity market risks may affect the trading value of the Notes and the amount due on the Notes;

FWP-10

· As a holder of the Notes, you will not have any ownership interest or rights in the stocks or other securities tracked by an Index;

· We or our affiliates are not affiliated with any of the Reference Sponsors; and

· Our or our affiliates business activities relating to the stocks or securities tracked by an equity index may create conflicts of interest with you.

Uncertain tax treatment.

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 of income in respect of the securities. 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.

DETERMINING PAYMENT AT MATURITY

On the maturity date, you will receive a cash payment (the Payment at Maturity) per security calculated as follows:

Hypothetical Payout Profile

The following profile is based on a hypothetical Maximum Cap of 45.50% (the midpoint of the Maximum Cap range of [43%-48%]), an Upside Participation Rate of 130% and a Buffer Value of -15.00%. This graph has been prepared for purposes of illustration only. Your actual return on the securities will depend on the actual Maximum Cap and the Final Level, and whether you hold your securities to maturity.

 

FWP-12

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. 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 Payment at Maturity 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 Payment at Maturity 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 and Price to Public:	$1,000
4	Hypothetical Initial Level*:	1,000.00
4	Upside Participation Rate:	130%
4	Hypothetical Maximum Cap*:	45.50% (the midpoint of the Maximum Cap range of [43%-48%])
4	Buffer Value:	-15.00%

* The actual Initial Level and Maximum Cap will be determined on the Pricing Date.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Securities
2,000.00	100.00%	$1,455.00	45.50%
1,800.00	80.00%	$1,455.00	45.50%
1,600.00	60.00%	$1,455.00	45.50%
1,400.00	40.00%	$1,455.00	45.50%
1,350.00	35.00%	$1,455.00	45.50%
1,200.00	20.00%	$1,260.00	26.00%
1,100.00	10.00%	$1,130.00	13.00%
1,040.00	4.00%	$1,052.00	5.20%
1,020.00	2.00%	$1,026.00	2.60%
1,000.00	0.00%	$1,000.00	0.00%
980.00	-2.00%	$1,000.00	0.00%
950.00	-5.00%	$1,000.00	0.00%
900.00	-10.00%	$1,000.00	0.00%
850.00	-15.00%	$1,000.00	0.00%
800.00	-20.00%	$950.00	-5.00%
700.00	-30.00%	$850.00	-15.00%
600.00	-40.00%	$750.00	-25.00%
400.00	-60.00%	$550.00	-45.00%
200.00	-80.00%	$350.00	-65.00%
0.00	-100.00%	$150.00	-85.00%

FWP-13

The following examples indicate how the Payment at Maturity 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 1,000.00 to a Final Level of 1,400.00.

Reference Return:	40.00%
Payment at Maturity:	$1,455.00

Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is greater than the hypothetical Maximum Cap, the Payment at Maturity would be $1,455.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 45.50%)

= $1,455.00

Example 1 shows that you will receive the Principal Amount plus a return equal to the Maximum Cap when the Reference Return is positive and such Reference Return multiplied by the Upside Participation Rate exceeds the Maximum Cap. In addition to limiting your return on the securities, the Maximum Cap limits the positive effect of the Upside Participation Rate. If the Final Level is greater than the Initial Level, you will participate in the performance of the Reference Asset at a rate of 130% up to the Maximum Cap. However, the Upside Participation Rate will have no additional positive impact on your return on the securities for any Final Level that is greater than 135.00% of the Initial Level (based on the hypothetical Maximum Cap of 45.50%), since your return on the securities for any Final Level greater than 135.00% of the Initial Level will be limited by the Maximum Cap.

Example 2: The level of the Reference Asset increases from the Initial Level of 1,000.00 to a Final Level of 1,100.00.

Reference Return:	10.00%
Payment at Maturity:	$1,130.00

Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is less than the hypothetical Maximum Cap, the Payment at Maturity would be $1,130.00 per $1,000 Principal Amount, calculated as follows:

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

= $1,000 + ($1,000 × 10.00% × 130%)

= $1,130.00

Example 2 shows that you will receive the Principal Amount plus a return equal to the Reference Return multiplied by the Upside Participation Rate when such Reference Return is positive and, when multiplied by the Upside Participation Rate, equal to or less than the Maximum Cap.

Example 3: The level of the Reference Asset decreases from the Initial Level of 1,000.00 to a Final Level of 950.00.

Reference Return:	-5.00%
Payment at Maturity:	$1,000

Because the Reference Return is less than zero but greater than the Buffer Value of -15.00%, the Payment at Maturity would be $1,000 per $1,000 Principal Amount (a zero return).

Example 4: The level of the Reference Asset decreases from the Initial Level of 1,000.00 to a Final Level of 400.00

Reference Return:	-60.00%
Payment at Maturity:	$550.00

Because the Reference Return is less than the Buffer Value of -15.00%, the Payment at Maturity would be $550.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 15.00%)]

= $1,000 + [$1,000 × (-60.00% + 15.00%)]

= $550.00

Example 4 shows that you are exposed on a 1-to-1 basis to any decrease in the level of the Reference Asset beyond the Buffer Value of -15.00%. In that scenario, you will lose some or a significant portion (up to 85.00%) of the Principal Amount.

Description of the Reference Asset

The Russell 2000^® Index   The Reference Asset is designed to track the performance of the small capitalization segment of the United States equity market. All 2,000 stocks are traded on the New York Stock Exchange or NASDAQ, and the RTY consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 3000^® Index is composed of the 3,000 largest United States companies as determined by market capitalization and represents approximately 98% of the United States equity market.   The top 5 industry groups by market capitalization as of March 31, 2017 were: Financial Services, Technology, Producer Durables, Consumer Discretionary and Health Care.   For more information about the Reference Asset, see “The Russell 2000^® Index” beginning on page S-36 of the accompanying Equity Index Underlying Supplement.   Historical Performance of the Reference Asset   The following graph sets forth the historical performance of the Reference Asset based on the daily historical Official Closing Levels from January 1, 2008 through April 28, 2017. We obtained the Official 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 Official Closing Levels of the Reference Asset should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the Reference Asset on the Final Valuation Date.

FWP-15

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 the fifth business day 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 eight 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, and Wells Fargo Securities as the agents for the sale of the securities. Pursuant to the terms of a distribution agreement, the agents 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, including WFA, or will offer the securities directly to investors. The agents may resell the securities to other registered broker-dealers at the price to public less a concession not in excess of $22.50 (2.25%) per $1,000 Principal Amount of the securities. In addition to the concession allowed to WFA, Wells Fargo Securities will pay $0.75 (0.075%) per $1,000 Principal Amount of the securities of the agent’s discount to WFA as a distribution expense fee for each security sold by WFA. The agents or other registered broker-dealers propose to offer the securities at the price to public set forth on the cover page of this free writing prospectus. We will reimburse HSBC Securities (USA) Inc. for certain expenses in connection with its role in the offer and sale of the securities, and we will pay HSBC Securities (USA) Inc. a fee in connection with its role in the offer and sale of the securities.

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 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.

We expect that delivery of the securities will be made against payment for the securities on or about the Original Issue Date set forth on page FWP-2 of this document, which is more than three business days following the Trade Date. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the securities more than three business days prior to the Original Issue Date will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

FWP-16

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 short-term capital gain or loss.

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.

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.

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, U.S. Treasury regulations 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 terms of the securities and representations provided by us, our counsel is of the opinion that the securities should not be “delta-one” instruments, and therefore, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the securities. However, it is possible that the securities 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 securities, and following such occurrence the securities 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 securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the securities 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.

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.
