The Notes

HSBC Buffered Accelerated Market Participation Securities^TM (Buffered AMPS^TM) offer investors an enhanced upside exposure to the upside return of the referenced indices, while providing a pre-defined level of downside buffered protection at maturity.

For investors who seek exposure to the Reference Asset and who believe the Reference Asset will appreciate over the term of the Buffered AMPS^TM, the Buffered AMPS^TM provide an opportunity for accelerated returns (subject to a Maximum Cap). If the Reference Return is below the Buffer Percentage, then the Buffered AMPS^TM are subject to 1:1 exposure to any potential decline of the relevant Reference Asset beyond -10%.

If the relevant Reference Asset appreciates over the term of the Notes, you will realize 200% (2x) of the relevant Reference Asset appreciation up to the relevant Maximum Cap. If the relevant Reference Asset declines, you will lose 1% of your investment for every 1% decline in the relevant Reference Asset beyond the -10% Buffer Percentage.

Information about each Reference Asset
The S&P 500® Index is a capitalization-weighted index of 500 U.S. stocks. It is designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries.

The iShares^® MSCI Emerging Markets ETF tracks the performance of an index composed of emerging market stocks that can predominantly be classified as large and mid-cap.  

The XBI seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P^® Biotechnology Select Industry^® Index (the “underlying index”). The underlying index represents the biotechnology sub-industry portion of the S&P Total Market Index (“S&P TMI”), an index that measures the performance of the U.S. equity market. The XBI is composed of companies that are in the biotechnology sector. The returns of the XBI may be affected by certain management fees and other expenses, which are detailed in its prospectus.

The graphs above illustrate the daily performance of each Reference Asset from May 27, 2010 through May 27, 2020. Past performance is not necessarily an indication of future results. For further information on each Reference Asset, please see “Information Relating to the Reference Assets” beginning on page FWP-13 of this document. We have derived all disclosure regarding the Reference Assets from publicly available information.

GENERAL

This document relates to separate offerings of Notes, each linked to a different Reference Asset. The purchaser of a Note will acquire a senior unsecured debt security of HSBC USA Inc. linked to a single Reference Asset. We reserve the right to withdraw, cancel or modify any offering and to reject orders in whole or in part. Although each offering of Notes relates to a Reference Asset, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to such Reference Asset or any security included in such 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 either the Equity Index Underlying Supplement dated February 26, 2018 (for Notes linked to the SPX) or the ETF Underlying Supplement dated February 26, 2018 (for Notes linked to the EEM or the XBI), as applicable. If the terms of the Notes offered hereby are inconsistent with those described in the accompanying prospectus, prospectus supplement, or relevant 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-9 of this document, page S-1 of the prospectus supplement and either page S-1 of the Equity Index Underlying Supplement or page S-1 of the ETF Underlying Supplement, as applicable, 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 underlying supplements) with the SEC for the offerings to which this document relates.

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.

PS-6

PAYMENT AT MATURITY

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 relevant Reference Return is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, equal to the lesser of:

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

(b)       $1,000 + ($1,000 × Maximum Cap).

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

If the relevant 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:

$1,000 + ($1,000 × (Reference Return + 10%)).

Under these circumstances, you will lose 1% of the Principal Amount of your Notes for each percentage point that the Reference Return is below the Buffer Percentage. For example, if the Reference Return is -30%, you will suffer a 20% loss and receive 80% of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the relevant Reference Return is less than the Buffer Percentage, you will lose some or a significant portion (up to 90%) of your investment.

Interest

The Notes will not pay interest.

Calculation Agent

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

Reference Sponsor

S&P Dow Jones Indices LLC, a division of S&P Global, is the reference sponsor for the Notes linked to the SPX. iShares, Inc. is the reference sponsor for the Notes linked to the EEM. The reference sponsor of the XBI is the Select Sector SPDR Trust.

PS-7

4 You seek an investment with an enhanced return linked to the potential positive performance of the relevant Reference Asset and you believe the value of such Reference Asset will increase over the term of the Notes.

4 You are willing to invest in the Notes based on the Maximum Cap indicated herein with respect to that Note offering, which may limit your return at maturity. The actual Maximum Cap for each offering of Notes will be determined on the Pricing Date.

4 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 relevant Reference Return is less than -10%.

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

4 You are willing to forgo dividends or other distributions paid to holders of the stocks included in the relevant Reference Asset or the Reference Asset itself, as applicable.

4 You are unwilling to invest in the Notes based on the Maximum Cap indicated herein with respect to that Note offering, which may limit your return at maturity. The actual Maximum Cap for each offering of Notes will be determined on the Pricing Date.

4 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 relevant Reference Return is less than -10%.

4 You seek an investment that provides full return of principal.

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

4 You prefer to receive the dividends or other distributions paid on the stocks included in the relevant Reference Asset or the Reference Asset itself, as applicable.

4 You seek current income from your investment.

PS-8

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 in the accompanying prospectus supplement and either page S-1 of the Equity Index Underlying Supplement or page S-1 of the ETF Underlying Supplement, as applicable. 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 prospectus supplement, prospectus and relevant underlying supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and relevant underlying supplement including the explanation of risks relating to the Notes described in the following sections:

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

If your Notes are linked to the SPX:

4 “— General Risks Related to Indices” in the Equity Index Underlying Supplement;

If your Notes are linked to the EEM:

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

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

4 “— Time Differences Between the Domestic and Foreign Markets and New York City May Create Discrepancies in the Trading Level or Price of the Notes” in the ETF Underlying Supplement.

If your Notes are linked to the XBI:

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

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

Your investment in the Notes may result in a loss.

You will be exposed to the decline in the Final Value from the Initial Value beyond the Buffer Percentage of -10%. Accordingly, if the relevant Reference Return is less than -10%, your Payment at Maturity will be less than the Principal Amount of your Notes. You will lose some or a significant portion (up to 90%) of your investment at maturity if the relevant Reference Return is less than the Buffer Percentage.

The appreciation on the Notes is limited by the relevant Maximum Cap.

You will not participate in any appreciation in the value of the relevant Reference Asset (as multiplied by the Upside Participation Rate) beyond the relevant Maximum Cap. The Maximum Cap (to be determined on the Pricing Date) will be at least 16.30% with respect to the Notes linked to the SPX, at least 18.50% with respect to the Notes linked to the EEM and at least 35.00% with respect to the Notes linked to the XBI. You will not receive a return on the Notes greater than the relevant Maximum Cap.

The amount payable on the relevant Notes is not linked to the value of the relevant Reference Asset at any time other than on the Final Valuation Date.

The Final Value of the relevant Reference Asset will be based on the Official Closing Value of the relevant Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the value of the relevant Reference Asset appreciates prior to the Final Valuation Date but then decreases on the Final Valuation Date to a value that is equal to or less than its Initial Value, the Payment at Maturity will be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the value of the relevant Reference Asset prior to that decrease. Although the actual value of the relevant Reference Asset on the Maturity Date or at other times during the term of the Notes may be higher than its Final Value, the Payment at Maturity will be based solely on the Official Closing Value of the relevant Reference Asset on the Final Valuation Date.

The Notes are subject to the credit risk of HSBC USA Inc.

The Notes are senior unsecured debt obligations of the Issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the Notes will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the Notes, including any return of principal at maturity, depends on the ability of HSBC to satisfy its obligations

PS-9

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.

The Notes will not bear interest.

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

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

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

You will not have any ownership interest in the stocks included in a Reference Asset.

As a holder of the Notes, you will not have any ownership interest in the stocks included in a Reference Asset, such as rights to vote, dividend payments or other distributions. Because the return on the Notes will not reflect any dividends on those stocks, the Notes may underperform an investment in the stocks included in a Reference Asset.

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 payments due on 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 value 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 initially be used for customer account statements, if

PS-10

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 lack liquidity.

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

Potential conflicts of interest may exist.

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.

Uncertain tax treatment.

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

Risks associated with non-U.S. companies.

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

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

Although the equity securities that are held by the EEM are traded in currencies other than U.S. dollars, and your Notes are denominated in U.S. dollars, the amount payable on your Notes at maturity, if any, will not be adjusted for changes in the exchange rates between the U.S. dollar and the currencies in which these non-U.S. equity securities are denominated. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the value of the EEM and therefore your Notes. The amount we pay in respect of your Notes on the maturity date, if any, will be determined solely in accordance with the procedures described in this document.

Risks associated with emerging markets.

An investment in the Notes 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.

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 the relevant Reference Asset relative to its Initial Value. We cannot predict the Final Value of the relevant Reference Asset. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of the relevant Reference Asset to which your Notes are linked or the return on your Notes. With respect to the 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 those issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Payment at Maturity on a $1,000 investment in the 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 Payment at Maturity 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:

4	Principal Amount:	$1,000
4	Upside Participation Rate:	200%
4	Buffer Percentage:	-10%
4	Hypothetical Maximum Cap:	16.30% *
	* The actual Maximum Cap for each offering of Notes will be determined on the Pricing Date and with respect to the Notes linked to the SPX will be at least 16.30%, with respect to the Notes linked to the EEM will be at least 18.50% and with respect to the Notes linked to the XBI will be at least 35.00%.

Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Notes
100.00%	$1,163.00	16.30%
80.00%	$1,163.00	16.30%
60.00%	$1,163.00	16.30%
40.00%	$1,163.00	16.30%
30.00%	$1,163.00	16.30%
20.00%	$1,163.00	16.30%
15.00%	$1,163.00	16.30%
8.15%	$1,163.00	16.30%
5.00%	$1,100.00	10.00%
2.00%	$1,040.00	4.00%
1.00%	$1,020.00	2.00%

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 relevant Reference Return is 5.00%

Reference Return:	5.00%
Final Settlement Value:	$1,100.00

Because the relevant Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is less than the hypothetical Maximum Cap, the Final Settlement Value would be $1,100.00 per $1,000 Principal Amount, calculated as follows:

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

= $1,000 + ($1,000 × 5.00% ×200%)

= $1,100.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by the Upside Participation Rate when the Reference Asset appreciates and such Reference Return multiplied by the Upside Participation Rate does not exceed the hypothetical Maximum Cap.

Example 2: The relevant Reference Return is 20.00%

Reference Return:	20.00%
Final Settlement Value:	$1,163.00

Because the relevant Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is greater than the hypothetical Maximum Cap, the Final Settlement Value would be $1,163.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 16.30%)

= $1,163.00

Example 2 shows that you will receive the return of your principal investment plus a return equal to the hypothetical Maximum Cap when the relevant Reference Return is positive and such Reference Return multiplied by the Upside Participation Rate exceeds the hypothetical Maximum Cap.

Example 3: The relevant Reference Return is -5.00%

Reference Return:	-5.00%
Final Settlement Value:	$1,000.00

Because the relevant Reference Return is less than zero but greater than the Buffer Percentage of -10%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 3 shows that you will receive the return of your principal investment where the value of the relevant Reference Asset declines by no more than 10% over the term of the Notes.

Example 4: The relevant Reference Return is -40.00%

Reference Return:	-40.00%
Final Settlement Value:	$700.00

Because the relevant Reference Return is less than the Buffer Percentage of -10%, the Final Settlement Value would be $700.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 10%)]

= $1,000 + [$1,000 × (-40.00% + 10%)]

= $700.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the value of the Reference Asset beyond the Buffer Percentage of -10%. You will lose some or a significant portion (up to 90%) of your investment.

For the Notes linked to the XBI

The disclosure relating to the XBI contained below relates only to the offering of Notes linked to the XBI.

Description of the XBI

The SPDR^® S&P^® Biotech ETF (the “XBI”) is an investment portfolio maintained and managed by SSgA Funds Management, Inc. The inception date of the XBI is January 31, 2006. The XBI is an exchange traded fund that trades on NYSE Arca under the ticker symbol “XBI.”

The XBI seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P^® Biotechnology Select Industry^® Index (the “underlying index”). The underlying index represents the biotechnology sub-industry portion of the S&P Total Market Index (“S&P TMI”), an index that measures the performance of the U.S. equity market. The XBI is composed of companies that are in the biotechnology sector. The returns of the XBI may be affected by certain management fees and other expenses, which are detailed in its prospectus.

The XBI utilizes a “replication” investment approach in attempting to track the performance of its underlying index. The XBI typically invests in substantially all of the securities which comprise the underlying index in approximately the same proportions as the underlying index. The XBI will normally invest at least 80% of its total assets in the common stocks that comprise the underlying index.

Information provided to or filed with the SEC by the Select Sector SPDR^® Trust pursuant to the Securities Act of 1933 and the Investment Company Act of 1940 can be located by reference to SEC file numbers 333-57791 and 811-08837, respectively, through the SEC’s website at http://www.sec.gov.

The S&P^® Biotechnology Select Industry^® Index

The underlying index is an equal-weighted index that is designed to measure the performance of the biotechnology sub-industry portion of the S&P TMI. The S&P TMI includes all U.S. common equities listed on the NYSE (including NYSE Arca), the NYSE MKT, the NASDAQ Global Select Market, and the NASDAQ Capital Market. Each of the component stocks in the underlying index is a constituent company within the biotechnology sub-industry portion of the S&P TMI.

To be eligible for inclusion in the underlying index, companies must be in the S&P TMI and must be included in the relevant Global Industry Classification Standard (GICS) sub-industry. The GICS was developed to establish a global standard for categorizing companies into sectors and industries. In addition to the above, companies must satisfy one of the two following combined size and liquidity criteria:

float-adjusted market capitalization above US$500 million and float-adjusted liquidity ratio above 90%; or

float-adjusted market capitalization above US$400 million and float-adjusted liquidity ratio above 150%.

All U.S. companies satisfying these requirements are included in the underlying index. The total number of companies in the underlying index should be at least 35. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds above are included in order of their float-adjusted market capitalization to reach 35 constituents. Minimum market capitalization requirements may be relaxed to ensure there are at least 22 companies in the underlying index as of each rebalancing effective date.

Eligibility factors include:

Market Capitalization: Float-adjusted market capitalization should be at least US$400 million for inclusion in the underlying index. Existing index components must have a float-adjusted market capitalization of US$300 million to remain in the underlying index at each rebalancing.

Liquidity: The liquidity measurement used is a liquidity ratio, defined as dollar value traded over the previous 12-months divided by the float-adjusted market capitalization as of the underlying index rebalancing reference date. Stocks having a float-adjusted market capitalization above US$500 million must have a liquidity ratio greater than 90% to be eligible for addition to the underlying index. Stocks having a float-adjusted market capitalization between US$400 and US$500 million must have a liquidity ratio greater than 150% to be eligible for addition to the underlying index. Existing index constituents must have a liquidity ratio greater than 50% to remain in the underlying index at the quarterly rebalancing. The length of time to evaluate liquidity is reduced to the available trading period for IPOs or spin-offs that do not have 12 months of trading history.

Takeover Restrictions: At the discretion of S&P, constituents with shareholder ownership restrictions defined in company bylaws may be deemed ineligible for inclusion in the underlying index. Ownership restrictions preventing entities from replicating the index weight of a company may be excluded from the eligible universe or removed from the underlying index.

Turnover: S&P believes turnover in index membership should be avoided when possible. At times, a company may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the underlying index, not for continued membership. As a result, an index constituent that appears to violate the criteria for addition to the underlying index will not be deleted unless ongoing conditions warrant a change in the composition of the underlying index.

PS-15

Historical Performance of the XBI

The following graph sets forth the historical performance of the XBI based on the daily historical closing values from May 27, 2010 through May, 2020. We obtained the closing values 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 values of the XBI should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Price of the XBI on the Final Valuation Date.

EVENTS OF DEFAULT AND ACCELERATION

If the relevant Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the relevant Notes, the calculation agent will determine the accelerated payment due and payable in the same general manner as described in this document, except that in such a 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 of the relevant Reference Asset, 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 relevant Reference Asset on that scheduled trading day, then the accelerated Final Valuation Date for that 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.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the Notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the Notes from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this free writing prospectus relates, for distribution to other registered broker-dealers or will offer the Notes directly to investors. HSBC Securities (USA) Inc. proposes to offer the Notes at the price to public set forth on the cover page of this free writing prospectus. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 2.25% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers..

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

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

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 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.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one approach, a Note should be treated as a pre-paid executory contract with respect to the relevant 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 relevant Reference Asset. Pursuant to this approach, and subject to the discussion below regarding “constructive ownership transactions,” 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.

Despite the foregoing, U.S. holders (as defined under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement) should be aware that the Internal Revenue Code of 1986, as amended (the “Code”), contains a provision, Section 1260 of the Code, which sets forth rules which are applicable to what it refers to as “constructive ownership transactions.” Due to the manner in which it is drafted, the precise applicability of Section 1260 of the Code to any particular transaction is often uncertain. In general, a “constructive ownership transaction” includes a contract under which an investor will receive payment equal to or credit for the future value of any equity interest in a regulated investment company (such as shares of the EEM or the XBI (the “Underlying Shares”)). Under the “constructive ownership” rules, if an investment in the Notes is treated as a “constructive ownership transaction,” any long-term

PS-17

capital gain recognized by a U.S. holder in respect of a Note will be recharacterized as ordinary income to the extent such gain exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Code) (the “Excess Gain”). In addition, an interest charge will also apply to any deemed underpayment of tax in respect of any Excess Gain to the extent such gain would have resulted in gross income inclusion for the U.S. holder in taxable years prior to the taxable year of the sale, exchange or maturity of the Note (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale, exchange or maturity of the Note). Furthermore, unless otherwise established by clear and convincing evidence, the “net underlying long-term capital gain” is treated as zero.

Although the matter is not clear, there exists a risk that an investment in the Notes linked to the Underlying Shares will be treated as a “constructive ownership transaction.” If such treatment applies, it is not entirely clear to what extent any long-term capital gain recognized by a U.S. holder in respect of a Note linked to the Underlying Shares will be recharacterized as ordinary income. It is possible, for example, that the amount of the Excess Gain (if any) that would be recharacterized as ordinary income in respect of each Note linked to the Underlying Shares will equal the excess of (i) any long-term capital gain recognized by the U.S. holder in respect of such a Note over (ii) the “net underlying long-term capital gain” such U.S. holder would have had if such U.S. holder had acquired a number of the Underlying Shares at fair market value on the original issue date of such Note for an amount equal to the “issue price” of the Note and, upon the date of sale, exchange or maturity of the Note, sold such Underlying Shares at fair market value (which would reflect the percentage increase in the value of the Underlying Shares over the term of the Note). Accordingly, it is possible that all or a portion of any gain on the sale or settlement of a Note linked to the Underlying Shares after one year could be treated as “Excess Gain” from a “constructive ownership transaction,” which gain would be recharacterized as ordinary income, and subject to an interest charge. U.S. holders should consult their tax advisors regarding the potential application of the “constructive ownership” rules.

We will not attempt to ascertain whether the relevant Reference Asset or any of the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If the relevant Reference Asset or one or more of the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the relevant Reference Asset and the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, and consult your tax advisor regarding the possible consequences to you if the relevant Reference Asset or one or more of the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, is or becomes a PFIC or a USRPHC.

Under current law, while the matter is not entirely clear, individual non-U.S. holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, the Notes are likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in the Notes.

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 relevant 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 relevant 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.
