The Buffered Digital Notes (each a “note” and collectively the “notes") offered hereunder will not be listed on any U.S. securities exchange or automated quotation system. The notes will not bear interest.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the notes or passed upon the accuracy or the adequacy of this document, the accompanying prospectus, prospectus supplement or Equity Index Underlying Supplement. Any representation to the contrary is a criminal offense. We have appointed HSBC Securities (USA) Inc., an affiliate of ours, as the agent for the sale of the notes. HSBC Securities (USA) Inc. will purchase the notes from us for distribution to other registered broker-dealers or will offer the notes directly to investors. In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions in any notes after their initial sale. Unless we or our agent inform you otherwise in the confirmation of sale, the pricing supplement to which this free writing prospectus relates is being used in a market-making transaction. See “Supplemental Plan of Distribution (Conflicts of Interest)” on page FWP-20 of this document.

Investment in the notes involves certain risks. You should refer to “Risk Factors” beginning on page FWP- 7 of this document, page S-1 of the accompanying prospectus supplement and page S-1 of the accompanying Equity Index Underlying Supplement.

The Estimated Initial Value of the notes on the Pricing Date is expected to be between $840 and $940 per note, which will be less than the price to public. The market value of the notes at any time will reflect many factors and cannot be predicted with accuracy. See “Estimated Initial Value” on page FWP-4 and “Risk Factors” beginning on page FWP-7 of this document for further information.

¹ HSBC USA Inc. or one of its affiliates may pay varying underwriting discounts of up to 2.025% and per $1,000 Principal Amount in connection with the distribution of the notes to other registered broker-dealers. See “Supplemental Plan of Distribution (Conflicts of Interest)” on page FWP-20 of this document.

These Buffered Digital Notes may be suitable for investors who believe that the Reference Asset will increase modestly over the term of the notes.

If the Reference Return is greater than or equal to the Buffer Percentage, you will realize the Digital Upside Return at maturity (subject to the credit risk of HSBC). If the Reference Return exceeds the Digital Upside Return, the notes will not provide any additional return aside from the Digital Upside Return. If the Reference Return is less than zero but equal to or greater than -12%, you will still receive the Digital Upside Return. If the Reference Asset declines by more than 12%, you will lose 1% of your investment for every 1% decline of the Reference Asset beyond the Buffer Percentage.

⁽²⁾ Subject to adjustment as described under “Additional Terms of the Notes” in the accompanying Equity Index Underlying Supplement.

The graph above illustrates the performance of the Reference Asset from September 28, 2017 through June 15, 2020. The closing levels in the graph above were obtained from the Bloomberg Professional^® Service. Past performance is not necessarily an indication of future results. For further information on the Reference Asset, please see “Description of the Reference Asset” on page FWP-15 of this document. We have derived all disclosure regarding the Reference Asset from publicly available information. Neither HSBC USA Inc. nor any of its affiliates have undertaken any independent review of, or made any due diligence inquiry with respect to, the publicly available information about the Reference Asset.

This document relates to a single offering of Buffered Digital Notes. The notes will have the terms described in this document and the accompanying prospectus supplement, prospectus and Equity Index Underlying Supplement. If the terms of the notes offered hereby are inconsistent with those described in the accompanying prospectus supplement, prospectus or Equity Index Underlying Supplement, the terms described in this document shall control. You should be willing to forgo interest and dividend payments during the term of the notes and, if the Reference Return is less than -12%, lose up to 88% of your principal.

This document relates to an offering of notes linked to the performance of the Reference Asset. The purchaser of a note will acquire a senior unsecured debt security of HSBC USA Inc. linked to the Reference Asset as described below. The following key terms relate to the offering of notes:

This document relates to an offering of notes linked to the Reference Asset. The purchaser of a note will acquire a senior unsecured debt security of HSBC USA Inc. We reserve the right to withdraw, cancel or modify the offering and to reject orders in whole or in part. Although the offering of notes relates to the Reference Asset, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the Reference Asset or any component security included in the Reference Asset or as to the suitability of an investment in the notes.

You should read this document together with the prospectus dated February 26, 2018, the prospectus supplement dated February 26, 2018, and the Equity Index Underlying Supplement dated February 26, 2018. If the terms of the notes offered hereby are inconsistent with those described in the accompanying prospectus supplement, prospectus or Equity Index Underlying Supplement, the terms described in this document shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page FWP-7 of this document, page S-1 of the prospectus supplement and page S-1 of the Equity Index Underlying Supplement, as the notes 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 notes. 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, a prospectus supplement and Equity Index Underlying Supplement) with the SEC for the offering to which this document relates. Before you invest, you should read the prospectus, prospectus supplement and Equity Index Underlying Supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering. You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov. Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and Equity Index Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

We are using this document to solicit from you an offer to purchase the notes. You may revoke your offer to purchase the notes at any time prior to the time at which we accept your offer by notifying HSBC Securities (USA) Inc. We reserve the right to change the terms of, or reject any offer to purchase, the notes prior to their issuance. In the event of any material changes to the terms of the notes, we will notify you.

On the Maturity Date, for each note you hold, we will pay you the Final Settlement Value, which is an amount in cash, as described below:

If the Reference Return is greater than or equal to the Buffer Percentage, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of notes, equal to:

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

Under these circumstances, you will lose 1% of the Principal Amount for each percentage point that the Reference Return is less than the Buffer Percentage. For example, if the Reference Return is -40%, you will suffer a 28% loss and receive 72% of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the Reference Return is less than the Buffer Percentage, you will lose some or a significant portion (up to 88%) of your investment.

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

The notes may be suitable for you if:

You seek an investment with a return linked to the potential performance of the Reference Asset and you believe the level of the Reference Asset will not be less than the Buffer Percentage.

You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is less than the Buffer Percentage.

You are willing to invest in the notes based on the fact that your maximum potential return is the Digital Upside Return.

You are willing to accept the risk and return profile of the notes versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating.

You are willing to forgo dividends or other distributions paid to holders of the stocks included in the Reference Asset.

You do not seek current income from your investment.

You do not seek an investment for which there is an active secondary market.

You are willing to hold the notes to maturity.

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

The notes may not be suitable for you if:

You believe the Reference Return will be less than the Buffer Percentage.

You are unwilling to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is less than the Buffer Percentage.

You are unwilling to invest in the notes based on the fact that your maximum potential return is the Digital Upside Return.

You seek an investment that provides full return of principal.

You prefer the lower risk, and therefore accept the potentially lower returns, of conventional debt securities with comparable maturities issued by HSBC or another issuer with a similar credit rating.

You prefer to receive the dividends or other distributions paid on the stocks included in the Reference Asset.

You seek current income from your investment.

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

You are unable or unwilling to hold the notes to maturity.

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

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

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and Equity Index Underlying Supplement including the explanation of risks relating to the notes described in the following sections:

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

You will be exposed on a 1-to-1 basis to any decrease in the level of the Reference Asset beyond the Buffer Percentage of -12%. Accordingly, if the Reference Return is less than -12%, you will lose up to 88% of your investment at maturity.

You will not participate in any appreciation in the level of the Reference Asset and your return on the notes is limited to the Digital Upside Return.

The notes will not pay a return more than the Digital Upside Return. Even if the level of the Reference Asset appreciates over the term of the notes, you will not participate in that appreciation. Assuming the notes are held to maturity, the maximum return on the notes will not exceed the Digital Upside Return. Under no circumstances, regardless of the extent to which the level of the Reference Asset increases, will your return exceed the Digital Upside Return. In some cases, you may earn significantly less by investing in the notes than you would have earned by investing in an instrument directly linked to the performance of the Reference Asset, or by investing directly in the stocks included in the Reference Asset.

The amount payable on the notes is not linked to the level of the Reference Asset at any time other than 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 notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a level that is less than 88% of 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 notes may be higher than the Final Level, the Payment at Maturity will be based solely on the Official Closing Level of the Reference Asset on the Final Valuation Date.

The notes are senior unsecured debt obligations of the Issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the notes will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the notes, including any return of principal at maturity, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the notes and, in the event HSBC were to default on its obligations, you may not receive the amounts owed to you under the terms of the notes.

Changes that affect the Reference Asset may affect the market value of the notes and the amount you will receive at maturity.

The policies of the reference sponsor concerning additions, deletions and substitutions of the stocks included in the Reference Asset and the manner in which the reference sponsor takes account of certain changes affecting those stocks may affect the level of the Reference Asset. The policies of the reference sponsor with respect to the calculation of the Reference Asset could also affect the level of the Reference Asset. The reference sponsor may discontinue or suspend calculation or dissemination of the Reference Asset. Any such actions could affect the value of the notes and their return.

The notes are not insured or guaranteed by any governmental agency of the United States or any other jurisdiction.

The notes are not deposit liabilities or other obligations of a bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency or program of the United States or any other jurisdiction. An investment in the notes is subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations as they become due, you may not receive the full Payment at Maturity of the notes.

The Estimated Initial Value of the notes, which will be determined by us on the Pricing Date, is expected to be less than the price to public and may differ from the market value of the notes in the secondary market, if any.

The Estimated Initial Value of the notes will be calculated by us on the Pricing Date and is expected to be less than the price to public. The Estimated Initial Value will reflect our internal funding rate, which is the borrowing rate we pay to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the notes may be lower if it were based on the prices at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the notes to be more favorable to you. We will determine the value of the embedded derivatives in the notes by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the notes that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your notes in the secondary market (if any exists) at any time.

The price of your notes in the secondary market, if any, immediately after the Pricing Date is expected to be less than the price to public.

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the notes and the costs associated with structuring and hedging our obligations under the notes. If you were to sell your notes in the secondary market, if any, the price you would receive for your notes may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Reference Asset and changes in market conditions, and cannot be predicted with accuracy. The notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the notes to maturity. Any sale of the notes prior to maturity could result in a loss to you.

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

Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the notes in the secondary market, if any, and the value that may be initially 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 6 months after the Original Issue Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the notes and other costs in connection with the notes that we will no longer expect to incur over the term of the notes. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the notes and any agreement we may have with the distributors of the notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the notes based on changes in market conditions and other factors that cannot be predicted.

The notes will not be listed on any securities exchange. HSBC Securities (USA) Inc. is not required to offer to purchase the notes in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the notes.

An affiliate of HSBC has a minority equity interest in the owner of an electronic platform, through which we may make available certain structured investments offering materials. HSBC and its affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and hedging our obligations under the notes. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. We will not have any obligation to consider your interests as a holder of the notes in taking any action that might affect the value of your notes.

For a discussion of the U.S. federal income tax consequences of your investment in the notes, please see the discussion under “U.S. Federal Income Tax Considerations” herein and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

The Reference Asset was launched on September 26, 2017. Because the Reference Asset is of recent origin and limited actual historical performance data exists with respect to it, your investment in the securities may involve a greater risk than investing in securities linked to an index with a more established record of performance.

The historical performance of the Reference Asset should not be taken as an indication of its future performance. While the trading prices of the Index’s constituents (the “Index constituents”) will determine the Official Closing Level, it is impossible to predict whether the Official Closing Level will fall or rise. Trading prices of the Index constituents will be influenced by the complex and interrelated economic, financial, regulatory, geographic, judicial, tax, political and other factors that can affect the capital markets generally and the equity trading markets on which the Index constituents are traded, and by various circumstances that can influence the prices of the Index constituents. Due to the small number of Index constituents, the level of the Reference Asset may be materially affected by changes in the level of a small number of Index constituents, or even one Index constituent.

ICE Data Indices, LLC, as the Index Calculation Agent, may adjust the Reference Asset in a way that may affect its level, and the Index Calculation Agent has no obligation to consider your interests.

ICE Data Indices, LLC, as the Index Calculation Agent, Index Sponsor and Index Administrator, is responsible for calculating and maintaining the Reference Asset. The Index Sponsor can add, delete or substitute an Index constituent or make other methodological changes that could change the Official Closing Level. The Index Sponsor will determine, for example, which companies have an appropriate business for inclusion in the Reference Asset. Changes to the Index constituents may affect the Reference Asset, as a newly added equity security may perform significantly better or worse than the Index constituent or constituents it replaces. Additionally, the Index Sponsor may alter, discontinue or suspend calculation or dissemination of the Reference Asset. Any of these actions could adversely affect the value of the securities. As Index Calculation Agent, Index Sponsor and Index Administrator, ICE Data Indices, LLC has no obligation to consider your interests in calculating or revising the Reference Asset. See “Description of the Reference Asset.”

As discussed above, the Reference Asset was launched recently. The Index Sponsor has indicated that it expects to monitor the composition of the Reference Asset over time, including through discussions with market participants, in order to determine whether any changes to the Reference Asset or its components are necessary or appropriate. Because the Reference Asset currently has only 10 components, any additions to or deletions from the Reference Asset could have a significant impact on future levels of the Reference Asset.

HSBC and its affiliates have no affiliation with ICE Data Indices, LLC and are not responsible for any of their public disclosure of information.

HSBC and its affiliates are not affiliated with ICE Data Indices, LLC, as the Index Calculation Agent, Index Sponsor and Index Administrator (except for licensing arrangements discussed under “Description of the Reference Asset”) and have no ability to control or predict its actions, including any errors in or discontinuation of public disclosure regarding methods or policies relating to the calculation of the Reference Asset. If the Index Sponsor discontinues or suspends the calculation of the Reference Asset, it may become difficult to determine the market value of the securities and the payment at maturity, call or upon early redemption. The Calculation Agent may designate a successor index in its sole discretion. If the Calculation Agent determines in its sole discretion that no successor index comparable to the Reference Asset exists, the payment you receive at maturity, call or upon early redemption will be determined by the Calculation Agent in its sole discretion. See “Specific Terms of the Notes — Market Disruption Events” and “— Calculation Agent.” The Index Sponsor is not involved in the offer of the securities in any way and has no obligation to consider your interest as an owner of the securities in taking any actions that might affect the market value of your securities.

ICE Data Indices, LLC, as the Index Calculation Agent, Index Sponsor and Index Administrator is not involved in the offering of the securities in any way and it does not have any obligation of any sort with respect to your securities. ICE Data Indices, LLC, as Index Calculation Agent, Index Sponsor and Index Administrator does not have any obligation to take your interests into consideration for any reason, including when taking any actions that might affect the value of the securities.

We have derived the information about ICE Data Indices, LLC and the Reference Asset from publicly available information, without independent verification. Neither we nor any of our affiliates have undertaken any independent review of the publicly available information about ICE Data Indices, LLC, as the Index Calculation Agent, Index Sponsor and Index Administrator or the Reference Asset contained in this document. You, as an investor in the securities, should make your own independent investigation into the ICE Data Indices, LLC, as the Index Calculation Agent, Index Sponsor and Index Administrator and the Reference Asset.

The Index Calculation Agent may, in its sole discretion, discontinue the public disclosure of the intraday and Official Closing Level of the Index.

The Index Calculation Agent is under no obligation to continue to calculate the intraday Official Closing Level of the Reference Asset, or to calculate similar values for any successor index.

The Reference Asset lacks diversification and is vulnerable to fluctuations in the technology and consumer discretionary industries.

All of the stocks included in the Reference Asset are issued by companies whose primary lines of business are in the technology and consumer discretionary industries. As a result, the stocks that will determine the performance of the Reference Asset and hence, the value of the securities, are concentrated in two industries and vulnerable to events affecting those industries. Although an investment in the securities will not give holders any ownership or other direct interests in the Index constituents, the return on an investment in the securities will be subject to certain risks, including those described below, associated with a direct equity investment in companies in the technology and consumer discretionary industries. Accordingly, by investing in the securities, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors. The Reference Asset is also subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and may not be able to attain the high growth rate of smaller companies, especially during extended periods of economic expansion.

The Reference Asset currently includes constituents in the following categories:

A limited number of Index constituents may affect the Official Closing Level, and the Reference Asset is not necessarily representative of its focus industry.

Each of the Index constituents represents 10% of the weight of the Reference Asset as of each quarterly rebalancing date (based on the 10 Index constituents as of the date of this document). Any reduction in the market price of any of those stocks is likely to have a substantial adverse impact on the Official Closing Level and the value of the securities. Due to the small number of Index constituents, those Index constituents and the Reference Asset itself may not necessarily follow the price movements of the entire technology and consumer discretionary industries. If the Index constituents decline in value, the Reference Asset will also decline in value, even if common stock prices of other companies in the technology and consumer discretionary industries generally increase in value. Giving effect to leverage, negative changes in the performance of one Index constituent will be magnified and have a material adverse effect on the value of the securities.

An Index constituent may be replaced upon the occurrence of certain adverse events.

An exchange may delist an Index constituent. Procedures have been established by the Index Sponsor to address such an event. Because there are only 10 Index constituents as of the date of this document, there can be no assurance that the replacement or delisting of the Index constituents, or any other force majeure event, will not have an adverse or distortive effect on the Official Closing Level or the manner in which it is calculated and, therefore, may have any adverse impact on the value of the securities. An Index constituent may also be removed from the Reference Asset, as described under “Description of the Reference Asset.”

The Reference Asset uses a proprietary selection methodology, which may not select the constituent issuers in the same manner as would other index providers or market participants.

Using a proprietary methodology discussed below, the Reference Asset seeks to identify constituent issuers that exhibit characteristics of highly-traded, high-growth technology and internet/media stocks. When selecting future constituent issuers, the Index Sponsor will focus on distinguishing between traditional technology and service companies and newer, innovative, technology-utilizing companies. There can be no assurances that the proprietary methodology used to identify constituent issuers eligible for inclusion in the Reference Asset will be successful. The Index Sponsor’s methodology, to some extent, involves subjective judgments, and there can be no assurance that any or all constituent issuers included in the Reference Asset would be selected by other market participants using a similar selection process. See “Description of the Reference Asset—Index Constituent Selection.”

The Reference Asset seeks to identify constituent issuers that exhibit characteristics of highly-traded stocks.

The Reference Asset seeks to identify constituent issuers that exhibit characteristics of highly-traded, high-growth technology and internet/media stocks. Highly-traded stocks may be more susceptible to periods of over-valuation followed by “corrections” or rapid decreases in share price and may also be more sensitive to general market fluctuations or shocks. Consequently, the price of the constituents, and therefore the level of the Reference Asset, may decrease more rapidly during periods of market stress than other less highly-traded constituents or indices.

We are not currently affiliated with any of the constituent issuers. As a result, we have no ability, nor expect to have the ability in the future, to control the actions of such constituent issuers, including actions that could affect the value of the Index constituents or the value of your securities, and we are not responsible for any disclosure made by any other company. None of the money you pay us will go to any of the constituent issuers represented in the Reference Asset and none of the constituent issuers will be involved in the offering of the securities

in any way. The constituent issuers will not have any obligation to consider your interests as a holder of the securities in taking any corporate actions that might affect the value of your securities. In the event we become affiliated with any of the constituent issuers, we will have no obligation to consider your interests as a holder of the securities in taking any action with respect to such constituent issuer that might affect the value of your securities.

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 actual 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 notes. The Final Settlement Value may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including such a security issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Final Settlement Value on a $1,000 investment in the notes 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 Notes” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount to $1,000. The potential returns described here assume that your notes are held to maturity. You should consider carefully whether the notes are suitable to your investment goals. The following table and examples assume the following:

The following examples indicate how the Final Settlement Value would be calculated with respect to a hypothetical $1,000 investment in the notes.

Example 1: The level of the Reference Asset increases from the Initial Level of 1,000.00 to a Final Level of 1,050.00.

Because the Reference Return is positive, the investor receives the Digital Upside Return, and the Final Settlement Value would be $1,170.00 per $1,000 Principal Amount, calculated as follows:

Example 1 shows that you will benefit from the Digital Upside Return at maturity when the Reference Return is positive.

Example 2: The level of the Reference Asset increases from the Initial Level of 1,000.00 to a Final Level of 1,600.00.

Even if the Reference Return is positive, and greater than the Digital Upside Return, the Final Settlement Value would still be $1,170.00 per $1,000 Principal Amount of notes, calculated as follows:

Example 2 shows that you will not receive any return of your principal investment in addition to the Digital Upside Return at maturity when the Reference Return is greater than the Digital Upside Return.

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

Because the Reference Return is greater than the Buffer Percentage of -12%, the Final Settlement Value would be $1,170.00 per $1,000 Principal Amount of notes, calculated as follows:

Example 3 shows that you will receive the Digital Upside Return at maturity when the Reference Return is equal to or greater than the Buffer Percentage.

Example 4: The level of the Reference Asset decreases from the Initial Level of 1,000.00 to a Final Level of 500.00.

Because the Reference Return is less than the Buffer Percentage of -12%, the Final Settlement Value would be $620.00 per $1,000 Principal Amount, calculated as follows:

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the level of the Reference Asset beyond the Buffer Percentage of -12%. YOU MAY LOSE UP TO 88% OF THE PRINCIPAL AMOUNT OF YOUR NOTES.

We have derived all information contained in this document regarding the Reference Asset (or the “Index”), including, without limitation, its make-up, performance, method of calculation and changes in its constituents, from publicly available sources. Such information reflects the policies of and is subject to change by ICE Data Indices, LLC (“ICE Data”), which is the Index Sponsor, Index Administrator and Index Calculation Agent. We have not undertaken any independent review or due diligence of such information. The Index Sponsor has no obligation to continue to publish, and may discontinue the publication of, the Index. The description of the Index is summarized from its governing methodology, which is available at www.theice.com/publicdocs/data/NYSE_FANGplus_Index_Methodology.pdf. Neither the methodology nor any other information included on that website is included or incorporated by reference into this document.

The Index is an equal-dollar weighted index designed to represent a segment of the technology and consumer discretionary sectors consisting of highly-traded growth stocks of technology and tech-enabled companies such as Facebook, Inc., Apple Inc., Amazon.com, Inc., Netflix, Inc. and Google (Alphabet Inc.). The Index currently has 10 Index constituents, which is the minimum number, but it may have more than 10 Index constituents in the future. The Index was launched on September 26, 2017. As of the date of this document, the Index constituents are Facebook, Inc., Apple Inc., Amazon.com, Inc., Netflix, Inc., Google (Alphabet Inc.), Alibaba Group Holding Limited, Baidu, Inc., Nvidia Corporation, Tesla, Inc. and Twitter, Inc.

The Index universe will consist of all stocks classified as Consumer Discretionary or Technology by the Index Sponsor that are listed on a major U.S. stock exchange, such as the NYSE, Nasdaq or NYSE American. American Depositary Receipts are eligible for inclusion in the Index.

At each quarterly rebalance, the Index universe will be screened utilizing a proprietary methodology that references, among other factors, sector classification, revenue growth and an analysis of the applicable issuer’s business. The following steps will be executed:

The general aim of the quarterly rebalance of the Index is to ensure that the selection and weightings of the Index constituents continues to reflect as closely as possible the Index’s objective of representing a segment of the technology and consumer discretionary sectors consisting of the most highly-traded and high-growth technology and internet/media stocks such as Facebook, Inc., Apple Inc., Amazon.com, Inc., Netflix, Inc., Google (Alphabet Inc.).

The Index Administrator reserves the right to, at any time, change the number of stocks comprising the Index by adding or deleting one or more stocks, or replacing one or more stocks contained in the Index with one or more substitute stocks of its choice, if in the Index Administrator’s discretion such addition, deletion or substitution is necessary or appropriate to maintain the quality and/or character of the Index. Any such action would need to be approved by the Governance Committee.

Changes to the Index constituents may occur during a scheduled rebalance and as a result of the removal of an Index constituent. The quarterly Index rebalance becomes effective after the close of the third Friday of March, June, September, and December. The rebalance announcement will be made after the close of the Wednesday preceding that third Friday. The reference date for all company-specific data and information utilized in the rebalancing process will be taken from that same day, with exception of the prices utilized to determine the shares, which will be taken from the third Friday.

At quarterly Index rebalances, the Index will be rebalances according to the methodology described above under “—Index Universe” and “—Index Constituent Selection.”

The Index is calculated on a price return basis. The current Index level would be calculated by dividing the current modified Index market capitalization by the Index divisor. The divisor was determined based on the initial capitalization base of the Index and the base level. The divisor is updated as a result of corporate actions and composition changes. The general formula for the Index is:

Qi,t means the number of shares of Index constituent i on Index Calculation Date t

Index Calculation Date means a U.S. Business Day where all of the Constituent Exchanges are open.

The Index Divisor Dt will be adjusted for corporate actions and any additions, deletions, and share changes for the Index Constituents:

APCi,t means the Adjusted Previous Close Price (for corporate actions, and, denominated in the Index Base Currency) of Index Constituent i on Index Calculation Date t

Qi,t means the number of shares of Index constituent i on Index Calculation Date t

The Base Date for the Index is September 19, 2014, and the Base Level is 1,000.00.

General. The Index may be adjusted in order to maintain the continuity of the Index level and the composition. Adjustments take place in reaction to events that occur with Index constituents in order to mitigate or eliminate the effect of that event on Index performance.

Removal of constituents. Any Index constituent deleted from the Index as a result of a corporate action such as a merger, acquisition, spin-off, delisting or bankruptcy will be replaced by a new stock. Thus, the total number of Index constituents in the Index will stay constant. The Governance Committee would select a replacement stock that reflects the Index’s objective and is in line with the rebalancing selection criteria as set forth above under “—Index Universe” and “—Index Constituent Selection.” If an Index constituent is removed and replaced in the Index, the divisor will be adjusted to maintain the Index level.

Suspensions and company distress. Immediately upon an Index constituent filing for bankruptcy, an announcement will be made to remove the stock from the Index effective for the next business day following the bankruptcy. If the stock is trading on an over-the-counter (OTC) market, the last trade or price on that market is utilized as the deletion price on that day.

If the stock does not trade on the relevant exchange between the bankruptcy announcement and the deletion effective date, the stock may be deleted from the Index in that corporate action with a presumed market value of $0.

Price sources. In the event that the trading in shares is suspended or halted, the last known price established during regular daytime trading on the primary exchange will be used. Depending on the particular situation, the Index Administrator may choose to value the security at a price of $0 for purposes of Index calculation and/or Index corporate action. This would be applicable for certain extreme cases such as a company bankruptcy or severe distress when the security is no longer tradeable.

Spin-offs. The closing price of the Index constituent is adjusted by the value of the spin-off, and the shares of the Index constituent will be adjusted to maintain its existing weighting in the Index. The divisor will be adjusted to account for any changes in the overall Index market capitalization. Spun-off companies will not be added into the Index at the time of the event.

Dividends. The Index calculation incorporates regular cash dividends paid on the Index constituents and reinvests those distributions into the Index at the open of the dividend ex-date.

In the event of a rights issue, the price is adjusted for the value of the right before the open on the ex-date, and the shares are increased to maintain the Index constituent’s existing weighting within the Index. The adjustment assumes that the rights issue is fully subscribed. The amount of the price adjustment is determined from the terms of the rights issue, including the subscription price, and the price of the underlying security. The Index Administrator shall only enact adjustments if the rights represent a positive value, or are in-the-money, or alternatively, represent or can be converted into a tangible cash value.

Bonus issues, stock splits and reverse stock splits. For bonus issues, stock splits and reverse stock splits, the number of shares included in the Index will be adjusted in accordance with the ratio given in the corporate action. Since the event will also incorporate a corresponding price adjustment and will not change the value of the company included in the Index, the divisor will not be changed because of this.

Changes in number of shares. Changes in the number of shares outstanding, typically due to share repurchases, tenders, or offerings, will not be reflected in the Index.

ICE Data is responsible for the day-to-day management of the Index, including retaining primary responsibility for all aspects of the Index determination process, including implementing appropriate governance and oversight, as required under the International Organization of Securities Commission’s Principles for Financial Benchmarks (the “IOSCO Principles”). The Governance Committee is responsible for helping to ensure ICE Data’s overall compliance with the IOSCO Principles, by performing the Oversight Function which includes overseeing the Index development, design, issuance and operation of the Index, as well as reviewing the control framework. ICE Data is also responsible for decisions regarding the interpretation of the Index methodology and the Governance Committee is responsible for reviewing all rule book modifications and Index constituent changes to ensure that they are made objectively, without bias, and in accordance with applicable law and regulation and ICE Data’s policies and procedures. Consequently, all ICE Data’s and the Governance Committee discussions and decisions are confidential until released to the public.

Cases not covered in the methodology. In cases which are not expressly covered in the methodology, operational adjustments will take place along the lines of the aim of the Index. Operational adjustments may also take place if, in the opinion of the Index Administrator, it is desirable to do so to maintain a fair and orderly market in derivatives on the Index and/or this is in the best interests of the investors in products based on the Index and/or the proper functioning of the markets. Any such modifications described in this paragraph will also be governed by any applicable and outstanding policies and procedures in place by ICE Data at such time.

Methodology changes. The Governance Committee reviews all methodology modifications and Index changes to ensure that they are made objectively, without bias and in accordance with applicable law and regulation and ICE Data’s policies and procedures. The methodology may be supplemented, amended in whole or in part, revised or withdrawn at any time. Supplements, amendments, revisions and withdrawals may also lead to changes in the way the Index is compiled or calculated or affect the Index in another way. Any such modifications described in this paragraph will also be governed by any applicable and outstanding policies and procedures in place by ICE Data at such time.

The Index is calculated from 9:30 a.m. until 6:00 p.m. Eastern Time on those days specified as “Index Business Days,” as that term is defined in the Index methodology. Solely for the purpose of the preceding sentence and not for the purpose of any calculation of the value of the securities, Index Business Days will be classified as days on which the U.S. Equity Markets (NYSE, Nasdaq, and NYSE American) are open for a full or partial day of trading.

The Index Administrator retains the right to delay the publication of the opening level of the Index. Furthermore, the Index Administrator retains the right to suspend the publication of the level of the Index if it believes that circumstances prevent the proper calculation of the Index.

If Index constituent prices are cancelled, the Index will not be recalculated unless the Index Administrator decides otherwise.

Commercially reasonable efforts are made to ensure the correctness and validity of data used in real-time Index calculations. If incorrect price or corporate action data affects Index daily highs, lows, or closes, it is corrected retroactively as soon as possible and all revisions are communicated out to the public and market data vendors.

Changes to the Index methodology which arise as a result of market feedback, consultations, internal reviews, or otherwise will be communicated by an Index announcement which will be distributed by ICE Data Indices at https://www.theice.com/market-data/indices/equity-indices and NYSE Market Data at https://www.theice.com/market-data/indices/equity-indices/products. The information included in those websites will not be deemed to be included or incorporated by reference in this document.

As a general rule, the announcement periods that are mentioned below will be applied. However, urgently required corporate action treatments, often resulting from late notices from the relevant company or exchange, may require the Index Administrator to deviate from the standard timing.

Inclusion of new Index constituents. The inclusion of new companies in the Index will typically only occur during the quarterly rebalance, although there could be exceptions based on a specific corporate action affecting a current Index constituent during the year. The inclusion of the new company will be announced at least one week before the effective date of the actual inclusion. For example, for the rebalance effective for September 18, 2018, the announcement would have occurred after the close on September 6, 2018.

Removal of Index constituents. Index constituents would be removed from the Index as a result of periodic corporate actions as well as the results of the quarterly rebalance. All removals will be announced at least three trading days before the effective date of the removal. It should be noted that in the case of mergers and acquisitions, every effort will be made to remove the company at some reasonable time ahead of the suspension in trading in the acquired company. There will be certain situations and corporate actions that would require the removal of a company that has already ceased trading. In those cases, the company will be removed from the Index at its last traded price, or, at the discretion of the Index Administrator, at a derived price that most accurately represents its post-suspension value.

Corporate actions. In case of an event that could affect one or more Index constituents, the Index Administrator will inform the market about the intended treatment of the event in the Index shortly after the firm details have become available and have been confirmed. When possible, the corporate action will be announced, even if not all information is known, at least one trading day before the effective date of the action. Once the corporate action has been effectuated, the Index Administrator will confirm the changes in a separate announcement.

Methodology changes. Barring exceptional circumstances, a period of at least two months should pass between the date a proposed methodology change is published and the date it goes into effect. Exceptions can be made if the change is not in conflict with the interests of a “Stakeholder,” which specifically includes external parties that subscribe to the Index data or license it as the basis for an investment product, including, but not limited to, HSBC.

Reviews; publication of new selection. The new composition of the Index, including the companies to be a part of the Index and their corresponding new Index weights, will be announced at least three trading days before the effective date and can be accessed from NYSE Market Data at www.nyse.com/market-data/indices.

Any historical upward or downward trend in value of the Index during any period shown below is not an indication that the value of the Index is more or less likely to increase or decrease at any time during the term of the securities. The historical Index returns do not give an indication of the future performance of the Index. We cannot make any assurance that the future performance of the Index will result in holders of the securities receiving a positive return on their investment.

The following graph sets forth the historical performance of the Reference Asset based on the daily historical closing levels from September 28, 2017 through June 15, 2020. We obtained the closing levels below from the Bloomberg Professional® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional® service.

The historical levels of the 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.

If the notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the notes, the calculation agent will determine the accelerated payment due and payable at maturity in the same general manner as described in “Payment at Maturity” in this document. In that case, the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the Reference Return, and the accelerated Maturity Date will be three business days after the accelerated Final Valuation Date. If a Market Disruption Event exists with respect to the Reference Asset on that scheduled trading day, then the accelerated Final Valuation Date for the Reference Asset will be postponed for up to five scheduled trading days (in the same manner used for postponing the originally scheduled Final Valuation Date). The accelerated Maturity Date will also be postponed by an equal number of business days.

If the notes have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the notes. For more information, see “Description of Debt Securities — Senior Debt Securities — Events of Default” in the accompanying prospectus.

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the notes from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this free writing prospectus relates, for distribution to other registered broker-dealers, or will offer the notes directly to investors. HSBC Securities (USA) Inc. proposes to offer the notes at the price to public set forth on the cover page of this free writing prospectus. HSBC USA Inc. or one of its affiliates may pay varying underwriting discounts of up to 2.025% per $1,000 Principal Amount in connection with the distribution of the notes to other registered broker-dealers.

An affiliate of HSBC has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the notes.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the notes, but is under no obligation to make a market in the notes and may discontinue any market-making activities at any time without notice.

We expect that delivery of the notes will be made against payment for the notes on or about the Original Issue Date set forth on the inside cover page of this document, which is more than two 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 two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes 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.

There is no direct legal authority as to the proper tax treatment of the notes, and therefore significant aspects of the tax treatment of the notes are uncertain as to both the timing and character of any inclusion in income in respect of the notes. Under one approach, a note should be treated as a pre-paid executory contract with respect to the Reference Asset. We intend to treat the notes consistent with this approach. Pursuant to the terms of the notes, you agree to treat the notes under this approach for all U.S. federal income tax purposes. Subject to the limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Mayer Brown LLP, it is reasonable to treat a note as a pre-paid executory contract with respect to the Reference Asset. Pursuant to this approach, we do not intend to report any income or gain with respect to the notes prior to their maturity or an earlier sale or exchange and we intend to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the note for more than one year at such time for U.S. federal income tax purposes.

We will not attempt to ascertain whether any of the entities whose stock is included in 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 notes are likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in the notes.

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, 2023. Based on the Issuer’s determination that the notes are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the notes. However, it is possible that the notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Asset or the notes, and following such occurrence the notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the Reference Asset or the notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

For a discussion of the U.S. federal income tax consequences of your investment in a note, please see the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

PROSPECTIVE PURCHASERS OF NOTES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF NOTES.
