GENERAL

This free writing prospectus relates to an offering of securities linked to the Underlyings. The purchaser of a security will acquire a senior unsecured debt security of HSBC. We reserve the right to withdraw, cancel or modify this offering and to reject orders in whole or in part. Although the offering of securities relates to the Underlyings, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to either Underlying or any component security included in either Underlying or as to the suitability of an investment in the securities.

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

HSBC has filed a registration statement (including a prospectus, prospectus supplement, Equity Index Underlying Supplement and ETF Underlying Supplement) with the SEC for the offering to which this free writing prospectus relates. Before you invest, you should read the prospectus, prospectus supplement, Equity Index Underlying Supplement and ETF Underlying Supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering.

FWP-6

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 in the accompanying prospectus supplement, page S-1 in the accompanying Equity Index Underlying Supplement and page S-1 in the accompanying ETF Underlying Supplement. Investing in the securities is not equivalent to investing directly in any of the stocks included in or held by an Underlying. 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, Equity Index Underlying Supplement and ETF Underlying Supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement, Equity Index Underlying Supplement and ETF 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;

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

4 “— General Risks Related to Index Funds” in the ETF Underlying Supplement; and

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 ETF Underlying Supplement.

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

The securities do not guarantee any return of principal and you may lose all of your Principal Amount at maturity.

The securities do not guarantee any return of principal. The securities differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount if the securities are not automatically called and the Final Value of the Lowest Performing Underlying is less than its Barrier Value. In this case, the Payment at Maturity will be less than the Principal Amount and you will lose 1% for each 1% that the Final Value of the Lowest Performing Underlying is less than its Initial Value. You may lose up to 100% of your Principal Amount at maturity. Even if the Final Value of the Lowest Performing Index on the Final Valuation Date is greater than its Barrier Value, the amount you receive at stated maturity will not exceed the Principal Amount plus the final Contingent Coupon, if applicable, and your yield on the securities, taking into account any Contingent Coupons you may have received during the term of the securities, may be less than the yield you would earn if you bought a traditional interest-bearing debt securities of HSBC or another issuer with a similar credit rating.

You may not receive any Contingent Coupons.

We will not necessarily make periodic coupon payments on the securities. If the Official Closing Value of either Underlying on a Observation Date is less than its Coupon Trigger, we will not pay you the Contingent Coupon applicable to that Observation Date. If on each of the Observation Dates, the Official Closing Value of at least one Underlying is less than its Coupon Trigger, we will not pay you any Contingent Coupons during the term of, and you will not receive a positive return on, the securities. Generally, this non-payment of the Contingent Coupon coincides with a period of greater risk of principal loss on the securities.

Your return on the securities is limited to the Principal Amount plus the Contingent Coupons, if any, regardless of any appreciation in the value of either Underlying.

Whether the securities are automatically called or not, the maximum amount that you will receive on the securities will be the Principal Amount plus any Contingent Coupons, regardless of any appreciation in the value of either Underlying, which may be significant. Investors will not participate in any appreciation of either Underlying from its Initial Value. Accordingly, an investment in the securities may have a lower return than an investment in the stocks represented by an Underlying during the term of the securities.

The securities are subject to the 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 either Underlying 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 Contingent Coupons 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 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.

FWP-7

Changes that affect the RTY may affect its value and the market value of the securities and the amount you will receive on the securities.

The policies of the Reference Sponsor concerning additions, deletions and substitutions of the constituents included in or held by the RTY and the manner in which the Reference Sponsor takes account of certain changes affecting those constituents may affect the value of the RTY. The policies of the Reference Sponsor with respect to the calculation of the RTY could also affect the value of the RTY. The Reference Sponsor may discontinue or suspend calculation or dissemination of the RTY. Any such actions could affect the value of the RTY and the value of the securities.

Changes that affect the EEM or its underlying index may affect the price of the EEM and the market value of the securities and the amount you will receive on the securities.

The policies of the Reference Issuer or MSCI Inc. (the “Index Sponsor”), the index sponsor of its underlying index, concerning additions, deletions and substitutions of the constituents comprising the EEM or its underlying index, as applicable, and the manner in which the Reference Issuer or the Index Sponsor takes account of certain changes affecting those constituents included in the EEM or the underlying index may affect the price of the EEM. The policies of the Reference Issuer or the Index Sponsor with respect to the calculation of the EEM or the underlying index, as applicable, could also affect the price of the EEM. The Reference Issuer or the Index Sponsor may discontinue or suspend calculation or dissemination of the EEM or the underlying index, as applicable. Any such actions could affect the price of the EEM and the value of the securities.

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

If the securities are not automatically called, your return will be based on the Final Return of the Lowest Performing Underlying without regard to the performance of the other Underlyings. As a result, you could lose some or all of the Principal Amount if the Final Value of the Lowest Performing Underlying is less than its Barrier Value, even if there is an increase in the value of the other Underlyings. This could be the case even if one or both of the other Underlyings increased by an amount greater than the decrease in the Lowest Performing Underlying.

Since the securities are linked to the performance of more than one Underlying, you will be fully exposed to the risk of fluctuations in the value of each Underlying and correlation or lack thereof between the Underliers.

Since the securities are linked to the performance of more than one Underlying, the securities will be linked to the individual performance of each Underlying. Because the securities 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 value of each Underlying. For example, in the case of securities 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 securities, the individual performance of each of the Underlyings would not be combined to calculate your return and the depreciation of either Underlying would not be mitigated by the appreciation of any other Underlying. Instead, your return would depend on the Lowest Performing Underlying. In addition, the performances of the Underlyings may be positively or negatively correlated, or may not be correlated at all. If the Underlyings are not correlated to each other or are negatively correlated, there is a greater potential for one of the Underlyings to close below its Coupon Trigger on an Observation Date or its Barrier Value on the Final Valuation Date, respectively, and therefore the risk of missing a Contingent Coupon payment and that a loss of principal will occur is even greater. It is impossible to predict what the correlations between the Underlyings will be over the term of the securities. The RTY represents the small capitalization segment of the United States equity market and the EEM represents the equity markets in the global emerging markets. These different equity markets may not perform similarly over the term of the securities.

Higher Contingent Coupon Rates are generally associated with Underlyings with greater expected volatility and therefore can indicate a greater risk of loss.

“Volatility” refers to the frequency and magnitude of changes in the value of an Underlying. The greater the expected volatility with respect to an Underlying on the Pricing Date, the higher the expectation as of the Pricing Date that the value of the applicable Underlying could close below its Coupon Trigger on an Observation Date or its Barrier Value on the Final Valuation Date, respectively, indicating a higher expected risk of loss on the securities. 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 a higher Contingent Coupon Rate) than for similar securities linked to the performance of the applicable Underlying 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. The volatility of the Underlyings can change significantly over the term of the securities. The values of the Underlyings for your securities could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Underlyings and the potential to lose some or all of your principal at maturity.

FWP-8

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

If the securities are automatically called early, the holding period could be as little as 6 months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the securities at a comparable return for a similar level of risk in the event the securities are automatically called prior to the Maturity Date.

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 payments due on 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 values of the Underlyings 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 amount payable on the securities is not linked to the values of the Underlyings at any time other than the Observation Dates, including the Final Valuation Date.

The payments on the securities will be based on the Official Closing Values of the Underlyings on the Observation Dates, including the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. If the securities are not called, even if the value of the Lowest Performing Underlying is greater than or equal to its Coupon Trigger during the term of the securities other than on the Observation Dates but then decreases on each Observation Date to a value that is less than its Coupon Trigger, no Contingent Coupon will be payable. Similarly, even if the value of each Underlying is greater than or equal to its Barrier Value during the term of the securities other than on the Final Valuation Date but then decreases on the Final Valuation Date to a value that is less than its Barrier Value, the final Contingent Coupon will not be payable on the Maturity Date and the Payment at Maturity will be less, and possibly significantly less, than it would have been had the Payment at Maturity been linked to the value of the Lowest Performing Underlying prior to such decrease. Although the actual values of the Underlyings on the Maturity Date or at other times during the term of the securities may be higher than their respective values on the Observation Dates, whether the Contingent Coupons are payable and the Payment at Maturity will be determined based solely on the Official Closing Values of the Underlyings on the Observation Dates, including the Final Valuation Date.

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, “Risk Factors—Our trading, hedging and other business activities may create conflicts of interest with you” and “—There may be potential conflicts of interest involving the calculation agent, which is expected to be an affiliate of ours” in the ETF 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.

The securities are subject to small-capitalization risk. 

The RTY 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 value 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.

Risks associated with non-U.S. companies.

The EEM includes securities issued by foreign companies. You should be aware that investments in the securities will involve particular risks related to foreign securities. The foreign securities may have less liquidity and could be more volatile than many of the securities traded in the U.S. or other longer-established securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may affect levels or prices and volumes in those markets. Also, there is generally less publicly available information about foreign companies than about U.S. companies that are subject

FWP-10

to the reporting requirements of the Securities and Exchange Commission, and foreign companies often are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies. The other special risks associated with foreign securities may include, but are not necessarily limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of the EEM and, as a result, the market value of the securities and the return on the securities.

Risks associated with emerging markets.

An investment in securities linked to the EEM will involve risks not generally associated with investments which have no emerging market component. In particular, many emerging nations are undergoing rapid change, involving the restructuring of economic, political, financial and legal systems. Regulatory and tax environments may be subject to change without review or appeal. Many emerging markets suffer from underdevelopment of capital markets and tax regulation. The risk of expropriation and nationalization remains a threat. Guarding against such risks is made more difficult by low levels of corporate disclosure and unreliability of economic and financial data.

The price of the EEM is subject to currency exchange risk.

Because the price of the EEM is related to the U.S. dollar value of stocks included in the underlying index, holders of the securities will be exposed to currency exchange rate risk with respect to each of the currencies in which such component securities trade. Exchange rate movements for a particular currency are volatile and are the result of numerous factors including the supply of, and the demand for, those currencies, as well as relevant government policy, intervention or actions, but are also influenced significantly from time to time by political or economic developments, and by macroeconomic factors and speculative actions related to the relevant region. An investor’s net exposure will depend on the extent to which the currencies of the component securities strengthen or weaken against the U.S. dollar and the relative weight of each currency. If, taking into account such weighting, the dollar strengthens against the currencies of the component securities represented in the underlying index, the price of the EEM will be adversely affected and the payment at maturity on the securities may be reduced.

Historical values of an Underlying should not be taken as an indication of its future performance during the term of the securities.

The values of the Underlyings will determine the payments on the securities. It is impossible to predict whether the Official Closing Value of an Underlying will fall or rise compared to its Coupon Trigger or Barrier Value. The value of an Underlying will be influenced by complex and interrelated political, economic, financial and other factors that can affect the markets in which the securities included in that Underlying are traded and the prices of those securities. Accordingly, any historical values of an Underlying should not be taken as an indication of its future performance.

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

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

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

· The securities 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 securities;

· 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 securities 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 securities and the amount due on the securities;

· As a holder of the securities, you will not have any ownership interest or rights in the stocks or other securities held by the EEM or tracked by the RTY or the EEM’s underlying index;

· We or our affiliates are not affiliated with the Reference Sponsor or Reference Issuer;

FWP-11

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

· There will be limited anti-dilution adjustments with respect to the EEM;

· In some circumstances, the payment you receive on the securities may be based on the shares of an index fund other than the EEM or other property and not the EEM;

· The EEM and its underlying index are different;

· The EEM is subject to management risk;

· 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; and

· Time differences between the domestic and foreign markets and New York City may create discrepancies in the trading level or price of the securities.

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.

FWP-12

DETERMINING PAYMENT ON A COUPON PAYMENT DATE AND AT MATURITY

On each semi-annual Coupon Payment Date, if the securities have not been automatically called, whether a Contingent Coupon is payable depends on the Official Closing Value of each Underlying on the relevant Observation Date, as follows:

 

On the maturity date, if the securities have not been automatically called prior to maturity, you will receive a cash payment per security (the Payment at Maturity) calculated as follows:

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Valuation Date. The Lowest Performing Underlying is the Underlying with the lowest Final Return. The Final Return of an Underlying is its Final Value as compared to its Initial Value.

Step 2: Calculate the Payment at Maturity based on the Final Value of the Lowest Performing Underlying, as follows:

FWP-13

Hypothetical Payout Profile

The following profile illustrates the hypothetical Payment at Maturity on the securities (excluding the final Contingent Coupon, if payable) for a range of hypothetical performances of the Lowest Performing Underlying on the Final Valuation Date from its Initial Value to its Final Value, assuming the securities have not been automatically called prior to the maturity date. This graph has been prepared for purposes of illustration only. Your actual return on the securities will depend on the actual Final Value of the Lowest Performing Underlying and whether you hold your securities to maturity. The performance of the better performing Underlyings is not relevant to the Payment at Maturity.

 

FWP-14

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 value of either Underlying relative to its Initial Value. We cannot predict the Official Closing Value of either Underlying 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, and the hypothetical Initial Values used in the table and examples below are not expected to be the actual Initial Value of either Underlying. You should not take this illustration or these examples as an indication or assurance of the expected performance of either Underlying or return on the 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 and examples below illustrate the Payment at Maturity on a $1,000 investment in the securities for a hypothetical range of Final Returns of the Lowest Performing Underlying from -100% to +100%. The following results are based solely on the assumptions outlined below. The potential returns described here assume that the securities have not been automatically called prior to maturity. You should consider carefully whether the securities are suitable to your investment goals. If the Official Closing Value of each Underlying on every Observation Date is greater than or equal to its Coupon Trigger and the securities are not automatically called, the Contingent Coupons payable over the term of the securities would total $412.50 per $1,000 Principal Amount (assuming a Contingent Coupon Rate of 13.75% per annum, the midpoint of the Contingent Coupon Rate range). The following table and examples assume the following:

4	Principal Amount:	$1,000
4	Hypothetical Contingent Coupon Rate:	13.75% per annum (6.875% semi-annually) (the midpoint of the Contingent Coupon Rate range of [13.50%-14.00%] per annum)
4	Hypothetical Coupon Trigger:	85 with respect to the RTY and $85 with respect to the EEM (each of which is 85% of its  hypothetical Initial Value)
4	Hypothetical Barrier Value:	70 with respect to the RTY and $70 with respect to the EEM (each of which is 70% of its hypothetical Initial Value)
4	Hypothetical Initial Values:	100 with respect to the RTY and $100 with respect to the EEM

The actual Initial Value, Coupon Trigger and Barrier Value of each Underlying, and Contingent Coupon Rate will be determined on the Pricing Date.

Hypothetical Final Return of the Lowest Performing Underlying	Hypothetical Payment at Maturity (Excluding Any Contingent Coupons Payable on the Securities)
100.00%	$1,000.00
80.00%	$1,000.00
60.00%	$1,000.00
40.00%	$1,000.00
20.00%	$1,000.00
0.00%	$1,000.00
-10.00%	$1,000.00
-20.00%	$1,000.00
-25.00%	$1,000.00
-30.00%	$1,000.00
-40.00%	$600.00
-50.00%	$500.00
-60.00%	$400.00
-70.00%	$300.00
-80.00%	$200.00
-100.00%	$0.00

FWP-15

The following examples indicate how the Contingent Coupon payment and automatic call would be determined with respect to a hypothetical $1,000 investment in the securities.

Example 1: The value of each Underlying increases from its Initial Value to its Official Closing Value on a Call Observation Date.

Underlying	Initial Value	Official Closing Value
RTY	100.00	120.00 (120.00% of Initial Value)
EEM	$100.00	$140.00 (140.00% of Initial Value)

Because the Official Closing Value of each Underlying is above its Initial Value on a Call Observation Date, the securities are automatically called. You will receive $1,068.75 per $1,000 Principal Amount on the applicable Call Payment Date, calculated as follows:

$1,000 + Contingent Coupon

= $1,000 + ($1,000 × 6.875%)

= $1,068.75

Example 1 shows that, since the Official Closing Value of each Underlying is at or above its Initial Value on a Call Observation Date (which, starting on the second Observation Date, is also an Observation Date with respect to the determination whether the Contingent Coupon is payable), the securities will be automatically called, and you will receive your Principal Amount plus the Contingent Coupon on the applicable Call Payment Date. No extra payment will be made on account of the Official Closing Value of both Underlyings being above their respective Initial Values.

Example 2: The value of an Underlying decreases by 10% from its Initial Value to its Official Closing Value on a Call Observation Date.

Underlying	Initial Value	Official Closing Value
RTY	100.00	90.00 (90.00% of Initial Value)
EEM	$100.00	$110.00 (110.00% of Initial Value)

Because the Official Closing Value of an Underlying is below its Initial Value on a Call Observation Date, the securities are not called. However, since the Official Closing Value of that Underlying on a Call Observation Date is at or above its Coupon Trigger, you will receive the Contingent Coupon Payment of $68.75 on the applicable Coupon Payment Date, calculated as follows:

= ($1,000 × 6.875%)

= $68.75

Example 2 shows that, since the Official Closing Value of an Underlying is below its Initial Value on a Call Observation Date, the securities will not be called. However, since the Official Closing Value of that Underlying is at or above its Coupon Trigger on a Call Observation Date (which is also an Observation Date with respect to the determination whether the Contingent Coupon is payable on such Coupon Payment Date), you will receive a Contingent Coupon on the applicable Coupon Payment Date.

Example 3: The value of an Underlying decreases from its Initial Value to its Official Closing Value on a Call Observation Date by 60%.

Underlying	Initial Value	Official Closing Value
RTY	100.00	40.00 (40.00% of Initial Value)
EEM	$100.00	$120.00 (120.00% of Initial Value)

Because the Official Closing Value of an Underlying is below its Initial Value on the Call Observation Date, the securities are not called. In addition, because the Official Closing Value of that Underlying is below its Trigger Value on the Call Observation Date (which is also an Observation Date with respect to the determination of whether the Contingent Coupon is payable on such Coupon Payment Date), you will not receive a Contingent Coupon Payment on the Coupon Payment Date relating to such Call Observation Date.

FWP-16

Example 4: The securities have not been called prior to maturity and the value of the Lowest Performing Underlying decreases from its Initial Value by 60%.

Underlying	Initial Value	Final Value
RTY	100.00	40.00 (40.00% of Initial Value)
EEM	$100.00	$120.00 (120.00% of Initial Value)

RTY is the Lowest Performing Underlying. Because the Final Value of the Lowest Performing Underlying is below its Barrier Value and its Coupon Trigger, the Payment at Maturity would be $400.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Final Return of the Lowest Performing Underlying)

= $1,000 + ($1,000 × -60.00%)

= $400.00

The final Contingent Coupon will not be paid. Example 4 shows that you are exposed on a 1-to-1 basis to decrease in the value of the Lowest Performing Underlying if the Final Value of the Lowest Performing Underlying is below its Barrier Value. YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT.

FWP-17

ADDITIONAL TERMS OF THE SECURITIES

Payment on the Securities

Automatic Call

The securities will be automatically called if the Official Closing Value of each Underlying is at or above its Initial Value on any Call Observation Date. If the securities are automatically called, investors will receive a cash payment, per $1,000 in Principal Amount, equal to the Principal Amount, plus the applicable Contingent Coupon. No further payments will be made on the securities once they have been called.

Contingent Coupon

We will pay a semi-annual Contingent Coupon payment on a Coupon Payment Date if the Official Closing Value of each Underlying on the applicable Observation Date is greater than or equal to its Coupon Trigger. Otherwise, no coupon will be paid on such Coupon Payment Date. For information regarding the record dates applicable to the Contingent Coupons payable on the securities, please see the section entitled “Description of Notes — Interest and Principal Payments— Recipients of Interest Payments” beginning on page S-14 in the accompanying prospectus supplement. The Contingent Coupon Rate is [13.50%-14.00%] per annum, or [$67.50-$70.00] per $1,000 in Principal Amount semi-annually in equal installments (to be determined on the Pricing Date), if payable.

Payment at Maturity

On the Maturity Date, unless the securities are automatically called, for each security you hold, we will pay you the Payment at Maturity, which is an amount in cash, as described below:

nIf the Final Value of the Lowest Performing Underlying is greater than or equal to its Barrier Value:

$1,000 + final Contingent Coupon.

nIf the Final Value of the Lowest Performing Underlying is less than its Barrier Value:

$1,000 + ($1,000 × Final Return of the Lowest Performing Underlying).

If the securities are not automatically called prior to the Maturity Date and the Final Value of the Lowest Performing Underlying on the Final Valuation Date is less than its Barrier Value, you will lose more than 30%, and possibly all, of the Principal Amount of your securities.

Any return on the securities will be limited to the sum of your Contingent Coupons, if any. You will not participate in any appreciation of either Underlying, but you will have full downside exposure to the Lowest Performing Underlying on the Final Valuation Date if the Final Value of that Underlying is less than its Barrier Value.

Calculation Agent

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

Reference Sponsor and Reference Issuer

With respect to the RTY, FTSE Russell is the Reference Sponsor. With respect to the EEM, iShares, Inc. is the Reference Issuer.

Market Disruption Event

The provisions of this section supersede and replace the definition of “Market Disruption Event” set forth beginning on page S-56 of the accompanying Equity Index Underlying Supplement and page S-47 of the accompanying ETF Underlying Supplement.

A “Market Disruption Event” means, with respect to the RTY, 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 value of such Underlying 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 such Underlying 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

(4) an “Exchange Business Day” means any Scheduled Trading Day for such Underlying or any Successor Index on which each Relevant Stock Exchange for the securities underlying such Underlying or any Successor Index and each Related Futures or Options Exchange with respect to such Underlying or Successor Index 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” with respect to the RTY means a day, as determined by the calculation agent, on which (i) the Relevant Stock Exchanges with respect to each security underlying such Underlying 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 RTY 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 such Underlying.

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

A “Market Disruption Event” with respect to the EEM means, any of (A), (B), (C), (D), (E) or (F) below, 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 exchange or otherwise relating to the shares (or other applicable securities) of the EEM or any Successor Index Fund (as defined in the accompanying ETF Underlying Supplement) on the relevant stock exchange at any time during the one-hour period that ends at

FWP-19

the close of trading on such day, whether by reason of movements in price exceeding limits permitted by such relevant stock exchange 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 shares (or other applicable securities) of the EEM or any Successor Index Fund 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, shares (or other applicable securities) of the EEM or any Successor Index Fund on the relevant stock exchange 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 shares (or other applicable securities) of the EEM or any Successor Index Fund 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.

Postponement of the Valuation Dates and the Payment Dates

The provisions of this section supersede and replace the section entitled “Additional Terms of the Notes—Valuation Dates” on page S-58 of the accompanying Equity Index Underlying Supplement and page S-48 of the accompanying ETF Underlying Supplement.

Each of the Observation Dates, Call Observation Dates and the Final Valuation Date is a “Valuation Date.”

If a scheduled Observation Date is not a Scheduled Trading Day or a Market Disruption Event occurs or is continuing with respect to an Underlying on such Observation Date, then such Observation Date for such Underlying will be postponed to the first succeeding Scheduled Trading Day for such Underlying on which a Market Disruption Event for such Underlying 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 for such Underlying after the originally scheduled Observation Date, that eighth Scheduled Trading Day shall be deemed to be the Observation Date for such Underlying. If an Observation Date has been postponed eight Scheduled Trading Days for an Underlying after the originally scheduled Observation Date and a Market Disruption Event occurs or is continuing with respect to such Underlying on such eighth Scheduled Trading Day, the calculation agent will determine the Official Closing Value of such Underlying on such eighth Scheduled Trading Day (i) with respect to the EEM, based on its good faith estimate of the value of the shares of the EEM as of the close of trading on such eighth Scheduled Trading Day, or (ii) with respect to the RTY, in accordance with the formula for and method of calculating the Official Closing Value of the RTY 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. Notwithstanding the postponement of an Observation Date for an Underlying due to a non-Scheduled Trading Day or a Market Disruption Event with respect to such Underlying on such Observation Date, the originally scheduled Observation Date will remain the Observation Date for either Underlying not affected by a non-Scheduled Trading Day or a Market Disruption Event on such day.

If an Observation Date, Call Observation Date or the Final Observation Date is postponed for either Underlying, then the related Coupon Payment Date, Call Payment Date or Maturity Date will also be postponed by the same number of business days as the last postponed Observation Date, Call Observation Date or Final Valuation Date (in the event that any such date is postponed with respect to more than one Underlying), as the case may be, and no interest will be paid in respect of such postponement.

Index Fund Alteration Event

The provisions of this section supersede and replace the section entitled “Additional Terms of the Notes—Index Fund Alteration Event” on page S-51 of the accompanying ETF Underlying Supplement.

If at any time, the method of calculating the Reference Asset, any Successor Index Fund, or the related Underlying Index is changed in a material respect, or if the Reference Asset or any Successor Index Fund is in any other way modified so that the price of such fund does not, in the opinion of the calculation agent, fairly represent the price of such fund had such changes or modifications not been made, then the calculation agent may, at the close of business in New York City on the date that the Official Closing Price of the Reference Asset is to be determined, make such calculations and adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a closing price of the Reference Asset or such Successor Index Fund, as the case may be, as if such changes or modifications had not been made, and calculate the Final Price of the Reference Asset and the Payment at Maturity with reference to such adjusted closing price of the Reference Asset or such Successor Index Fund, as applicable.

Notwithstanding these adjustments, such event may affect the Reference Asset in a manner that adversely affects the value of the securities.

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 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.

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 Final Return of each Underlying, 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 an Underlying on that Scheduled Trading Day, then the accelerated Final Valuation Date for that Underlying 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 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 that Underlying’s Final Value will be made on such date, irrespective of the existence of a Market Disruption Event with respect to the other Underlying occurring on that date.

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, or will offer the securities directly to investors. The agents or other registered brokerdealers propose to offer the securities at the price to public set forth on the cover page of this free writing prospectus.

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.

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 two business days following the Trade Date. Under Rule 15c6-1 under the Exchange Act trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the securities more than two 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.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-61 in the prospectus supplement.

FWP-25

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 contingent income-bearing pre-paid executory contract with respect to the Underlyings. 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, Mayer Brown LLP, it is reasonable to treat a security as a contingent income-bearing pre-paid executory contract with respect to the Underlyings. 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 securities, other characterizations and treatments are possible and the timing and character of income in respect of the securities might differ from the treatment described herein. For example, the securities 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 securities as Indebtedness for U.S. Federal Income Tax Purposes — Contingent securities” in the accompanying prospectus supplement.

We will not attempt to ascertain whether any of the entities whose stock is included in the Underlyings 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 Underlyings 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 Underlyings and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Underlyings 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 securities Treated as a Put Option and a Deposit or an Executory Contract — Certain securities 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, exchange 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 security. Any such gain or loss will be long-term capital gain or loss if you have held the security for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a security generally will equal your cost of the security. 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, Internal Revenue Service guidance provides 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, 2021. Based on the Issuer’s determination that the securities are not “delta-one” instruments, 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 an Underlying 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 an Underlying 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.
