The Notes

The Notes may be suitable for investors who believe that the price of each Underlying will not decrease significantly over the term of the Notes and accept that the Notes are callable at our option on any Call Payment Date beginning on July 24, 2020. Unless the Notes are called prior to maturity, so long as the Official Closing Value of each Underlying on each Coupon Observation Date is greater than its Coupon Trigger, you will receive the quarterly Contingent Coupon on the applicable Coupon Payment Date.

On any Call Payment Date beginning on July 24, 2020, your Notes will be callable at our option. If the Notes are called, you will receive a payment equal to 100% of the Principal Amount, together with the applicable Contingent Coupon on the corresponding Call Payment Date.

If the Notes are not called prior to maturity and the Final Value of the Least Performing Underlying is greater than or equal to its Coupon Trigger, you will receive a Payment at Maturity equal to the Principal Amount of the Notes plus the final Contingent Coupon.

If the Notes are not called prior to maturity and the Final Value of each Underlying is less than its Coupon Trigger but greater than or equal to its Barrier Value, you will receive a Payment at Maturity equal to the Principal Amount.

If the Notes are not called prior to maturity and the Final Value of the Least Performing Underlying is less than its Barrier Value, you will lose 1% of your principal for every 1% decline of that Least Performing Underlying from its Initial Value. Even with any Contingent Coupons paid prior to maturity, your return on the Notes may be negative.

Illustration of Payment Scenarios

Your payment on the Notes will depend on whether the Notes have been called, whether the Official Closing Value of each Underlying on a Coupon Observation Date is greater than or equal to its Coupon Trigger, and whether the Final Value of the Least Performing Underlying is greater than or equal to its Barrier Value. If your Notes are not called, you will lose some or all of your Principal Amount at maturity if the Final Value of the Least Performing Underlying is less than its Barrier Value. In such a case, even with any Contingent Coupons, your return on the Notes will be negative.

PAYMENT ON THE NOTES

Call Feature

The Notes may be called at our option, in whole, but not in part, on each Call Payment Date. In order to call the Notes, we or the calculation agent will distribute written notice to The Depository Trust Company of our intent to call the Notes on or prior to the applicable Call Notice Date. We or the calculation agent will have no independent obligation to notify you directly and you should expect to receive such notifications from your broker. If the Notes are called, investors will receive on the corresponding Call Payment Date, a cash payment equal to 100% of the Principal Amount together with the applicable Contingent Coupon.

Contingent Coupon

We will pay a quarterly Contingent Coupon on a Coupon Payment Date if the Official Closing Value of each Underlying on the applicable Coupon Observation Date is equal to or greater than its Coupon Trigger. Otherwise, no coupon will be paid on such Coupon Payment Date. For information regarding the record dates applicable to the Contingent Coupons payable on the Notes, please see the section entitled “Description of the Notes—Recipients of Interest Payments” beginning on page S-14 in the accompanying prospectus supplement. The Contingent Coupon Rate will be at least 9.60% per annum (at least $24.00 per $1,000 in Principal Amount per quarter, if payable), to be determined on the Pricing Date.

Payment at Maturity

Unless the Notes are called prior to maturity, on the Maturity Date and for each $1,000 Principal Amount of Notes, you will receive a cash payment on the Maturity Date, calculated as follows:

n If the Reference Return of the Least Performing Underlying is greater than or equal to -40.00%:

$1,000 + final Contingent Coupon.

n If the Reference Return of the Least Performing Underlying is less than -40.00% but greater than or equal to -45.00%:

$1,000 (a zero return)

n If the Reference Return of the Least Performing Underlying is less than -45.00%:

$1,000 + ($1,000 × Reference Return of the Least Performing Underlying).

FWP-8

INVESTOR SUITABILITY

The Notes may be suitable for you if:

You believe that the Official Closing Value of each Underlying will be at or above its Coupon Trigger on most or all of the Coupon Observation Dates and if not, the Final Value of the Least Performing Underlying will be at or above its Barrier Value.

You are willing to accept that the quarterly Contingent Coupon (at a rate of at least 2.40%, to be determined on the Pricing Date) is contingent and is payable only if the Official Closing Value of each Underlying is greater than or equal to its Coupon Trigger on the applicable Coupon Observation Date.

You do not seek an investment that provides an opportunity to participate in the appreciation of any Underlying.

You are willing to make an investment that is exposed to the potential downside performance of the Least Performing Underlying on a 1-to-1 basis if the Notes are not called and the Reference Return of the Least Performing Underlying is less than -45.00%.

You are willing to lose up to 100% of the Principal Amount.

You are willing to hold Notes that will be callable at our option on any Call Payment Date or you are otherwise willing to hold the Notes to maturity.

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 on the stocks included in or held by the Underlyings.

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

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

The Notes may not be suitable for you if:

You believe that the Official Closing Value of at least one Underlying will be below its Coupon Trigger on most or all of the Coupon Observation Dates or the Final Value of the Least Performing Underlying will be below its Barrier Value.

You believe the quarterly Contingent Coupon (at a rate of at least 2.40%, to be determined on the Pricing Date) will not provide you with your desired return.

You seek an investment that provides an opportunity to participate in the appreciation of any Underlying.

You are unwilling to make an investment that is exposed to the potential downside performance of the Least Performing Underlying on a 1-to-1 basis if the Notes are not called and the Reference Return of the Least Performing Underlying is less than -45.00%.

You seek an investment that provides full return of principal at maturity.

You are unable or unwilling to hold Notes that will be callable at our option on any Call Payment Date or you are otherwise unable or unwilling to hold the Notes to maturity.

You prefer to receive guaranteed periodic interest payments on the Notes, or the dividends or other distributions paid on the stocks included in or held by the Underlyings.

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

FWP-9

RISK FACTORS

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

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

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

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

“—General Risks Related to the 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.

The Notes do not guarantee any return of principal and you may lose your entire initial investment.

The Notes do not guarantee any return of principal. The Notes differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount of your Notes if the Notes are not called prior to maturity and the Final Value of the Least Performing Underlying is less than its Barrier Value. In this case, the Payment at Maturity you will be entitled to receive will be less than the Principal Amount of the Notes and you will lose 1% for each 1% that the Reference Return of the Least Performing Underlying is less than -45.00%.You may lose up to 100% of your investment at maturity. Even with any Contingent Coupons, your return on the Notes will be negative in this case.

You may not receive any Contingent Coupons.

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

Your return on the Notes is limited to the Principal Amount plus the Contingent Coupons, if any, regardless of any appreciation in the price of the Underlyings.

Whether the Notes are called or held to maturity, the maximum payments on the Notes will be Principal Amount plus the Contingent Coupons, regardless of any appreciation in the price of the Underlyings, which may be significant. Accordingly, an investment in the Notes may have a lower return than an investment in the stocks represented by an Underlying during the term of the Notes.

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

The Notes are senior unsecured debt obligations of the Issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the Notes will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the Notes, including any Contingent Coupons and any return of principal at maturity or upon early redemption, as applicable, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the 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 may be called at our option prior to the Maturity Date.

If the Notes are called early, the holding period over which you may receive coupons could be as little as approximately 12 months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are called at our option prior to the Maturity Date.

If the Notes are not called, your return will be based on the Reference Return of the Least Performing Underlying.

If the Notes are not called prior to maturity, your return will be based on the Reference Return of the Least Performing Underlying without regard to the performance of any other Underlying. As a result, you could lose all or some of your initial investment if the Final Value of the Least Performing Underlying is less than its Barrier Value, even if there is an increase in the price of any other Underlying. This could be the case even if the other Underlyings increased by an amount greater than the decrease in the Least Performing Underlying.

Since the Notes are linked to the performance of more than one Underlying, you will be fully exposed to the risk of fluctuations in the price of each Underlying.

Since the Notes are linked to the performance of more than one Underlying, the Notes will be linked to the individual performance of each Underlying. Because the Notes are not linked to a weighted basket, in which the risk is mitigated and diversified among all of the

FWP-10

components of a basket, you will be exposed to the risk of fluctuations in the relevant level or price of each Underlying. For example, in the case of notes linked to a weighted basket, the return would depend on the weighted aggregate performance of the basket components reflected as the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component, as scaled by the weightings of such basket components. However, in the case of these Notes, the individual performance of each of the Underlyings would not be combined to calculate your return and the depreciation of one Underlying would not be mitigated by the appreciation of another Underlying. Instead, your return would depend on the Least Performing Underlying.

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

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

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

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

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

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes and the costs associated with structuring and hedging our obligations under the Notes. If you were to sell your Notes in the secondary market, if any, the price you would receive for your Notes may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the prices of the Underlyings 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 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

FWP-11

reimbursement period after the Original Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

The amount payable on the Notes is not linked to the value of the Underlyings at any time other than the Coupon Observation Dates, including the Final Valuation Date.

The payments on the Notes will be based on the Official Closing Values of the Underlyings on the Coupon Observation Dates, including the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the relevant level or price of each Underlying is greater than or equal to its Coupon Trigger during the term of the Notes other than on a Coupon Observation Date but then drops on a Coupon Observation Date to a level or price, as applicable, that is less than its Coupon Trigger, the Contingent Coupon will not be payable for the relevant quarter. Similarly, if the Notes are not called, even if the level or price of the Least Performing Underlying, as applicable, is greater than or equal to its Barrier Value during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a level or price that is less than the Barrier Value, the Payment at Maturity will be less, possibly significantly less, than it would have been had the Payment at Maturity been linked to the level or price of the Least Performing Underlying prior to such decrease. Although the actual level or price of the Underlyings, as applicable, on the Maturity Date or at other times during the term of the Notes may be higher than their respective level or price on the Coupon Observation Dates, whether each Contingent Coupon will be payable and the Payment at Maturity will be based solely on the Official Closing Values of the Underlyings on the applicable Coupon Observation Dates.

Changes that affect an Underlying or an underlying index may affect the price of an Underlying and the market value of the Notes and the amount you will receive on the Notes.

The policies of the reference sponsor or reference issuer of an Underlying, or the polices of a reference sponsor of an underlying index, if applicable, concerning additions, deletions and substitutions of the stocks included in or held by an Underlying or an underlying index, if applicable, and the manner in which the reference sponsors or reference issuer take account of certain changes affecting those stocks may affect the values of an Underlying. The policies of the reference sponsors or reference issuer with respect to the calculation of an Underlying, or the polices of a reference issuer with respect to an underlying index, if applicable, could also affect the values of that Underlying. The reference sponsors of an Underlying or applicable underlying index, or the reference issuer of an Underlying, may discontinue or suspend calculation or dissemination of an Underlying or underlying index. Any such actions could affect the value of and return on the Notes.

Owning the Notes is not the same as owning an Underlying or the stocks included in an applicable underlying index.

The return on your Notes may not reflect the return you would realize if you actually owned stocks included in or held by an Underlying or the related underlying index, if applicable. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or other rights as would holders of stock included in or held by an Underlying or the stocks included in a related underlying index, if applicable.

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 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.

Small-capitalization risk.

The RTY tracks companies that are considered small-capitalization. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the level of the RTY may be more volatile than an investment in stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded, making it difficult for the RTY to track them. In addition, small-capitalization companies are typically less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

Risks associated with the oil and gas exploration and production sector

All of the stocks held by the XOP are issued by companies in the oil and gas exploration and production sector. As a result, the stocks that will determine the performance of the XOP are concentrated in one sector. Although an investment in the Notes will not give holders any ownership or other direct interests in the stocks held by the XOP, the return on the Notes will be subject to certain risks associated with a direct equity investment in companies in the oil and gas exploration and production sector.

In addition, the stocks of companies in the oil and gas sector are subject to swift price fluctuations. The issuers of the stocks held by the XOP develop and produce, among other things, crude oil and natural gas, and provide, among other things, drilling services and other services related to oil and gas production and distribution. Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for oil and gas products in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. Correspondingly, the stocks of companies in this sector are subject to swift price fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects and tax and other governmental regulatory policies. Weak demand for the companies’ products or services or for oil and gas products and services in general, as well as negative developments in these other areas, would adversely impact the prices of the stocks held by the XOP, the market price of the XOP, and the value of the Notes.

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 price of any Underlying relative to its Initial Value. We cannot predict the Official Closing Value of any of the Underlyings on any Coupon Observation Date or the Final Valuation Date. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of any of the Underlyings or return on the Notes.

The table and examples below illustrate how the Contingent Coupon and the Payment at Maturity would be calculated with respect to a $1,000 investment in the Notes, given a range of hypothetical performances of any Underlying. The hypothetical returns on the Notes below are numbers, expressed as percentages, that result from comparing the Payment at Maturity per $1,000 Principal Amount to $1,000. The potential returns described here assume that we do not call the Notes and your Notes are held to maturity. You should consider carefully whether the Notes are suitable to your investment goals. The numbers appearing in the following table and examples have been rounded for ease of analysis. The following table and examples assume the following:

4 Principal Amount:	$1,000
4 Hypothetical Initial Value	1,000.00 with respect to the INDU and RTY, and $100.00 with respect to the XOP*
4 Hypothetical Barrier Value:	550.00 with respect to the INDU and RTY, and $55.00 with respect to XOP (55.00% of their respective Initial Values)*
4 Hypothetical Coupon Trigger:	600.00 with respect to the INDU and RTY, and $60.00 with respect to XOP (60.00% of their respective Initial Values)*
4 Hypothetical Contingent Coupon Rate:	9.60% per annum (2.40% for each quarter in which it is payable). The actual Contingent Coupon Rate will be at least 9.60% per annum and will be determined on the Pricing Date. If the Official Closing Value of each Underlying on every Coupon Observation Date is greater than or equal to its Coupon Trigger, the Contingent Coupon paid over the term of the Notes would total $480.00 per $1,000 Principal Amount of the Notes.

* The hypothetical Initial Values used in the examples below have been chosen for illustrative purposes only and does not represent the actual Initial Value of any Underlying. The actual Initial Value, Coupon Trigger and Barrier Value of each Underlying will be determined on the Pricing Date and set forth in the final pricing supplement to which this free writing prospectus relates.

Summary of the Examples

Hypothetical Reference Return of the Least Performing Underlying	Hypothetical Final Settlement Value	Hypothetical Return on the Notes (Excluding Any Contingent Coupons Payable Prior to the Maturity Date)
100.00%	$1,024.00	2.40%
80.00%	$1,024.00	2.40%
60.00%	$1,024.00	2.40%
40.00%	$1,024.00	2.40%
20.00%	$1,024.00	2.40%

-100.00%	$0.00	-100.00%

FWP-14

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 value of the Least Performing Underlying increases from its Initial Value to its Final Value by 60%.


Underlying	Initial Value	Final Value
INDU	1,000.00	1,700.00 (170% of its Initial Value)
RTY	1,000.00	1,700.00 (170% of its Initial Value)
XOP	$100.00	$160.00 (160% of its Initial Value)

XOP is the Least Performing Underlying. Because the price of XOP increases by 60% from its Initial Value to its Final Value, the Reference Return of the Least Performing Underlying is 60.00%, calculated as follows:

Final Value of XOP – Initial Value of XOP

Initial Value of XOP

($160.00 - $100.00) / $100.00 = 60.00%

Because the Final Value of the Least Performing Underlying is above its Barrier Value, the Final Settlement Value would be $1,024.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + Final Contingent Coupon

= $1,000 + ($1,000 × 2.40%)

= $1,024.00

Example 1 shows that you will receive the return of your principal investment plus the final Contingent Coupon when the Final Value of the Least Performing Underlying is above its Barrier Value and Coupon Trigger, even though the increase in the price of the Least Performing Underlying is significant.

Example 2: The value of the Least Performing Underlying decreases from its Initial Value to its Final Value by 20%.


Underlying	Initial Value	Final Value
INDU	1,000.00	800.00 (80% of its Initial Value)
RTY	1,000.00	900.00 (90% of its Initial Value)
XOP	$100.00	$130.00 (130% of its Initial Value)

INDU is the Least Performing Underlying. Because the level of INDU decreases by 20% from its Initial Value to its Final Value, the Reference Return of the Least Performing Underlying is -20.00%, calculated as follows:

Final Value of INDU – Initial Value of INDU

Initial Value of INDU

(800.00 – 1,000.00) / 1,000.00 = -20.00%

Because the Final Value of the Least Performing Underlying is greater than or equal to its Coupon Trigger, the Final Settlement Value would be $1,024.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + Final Contingent Coupon

= $1,000 + ($1,000 × 2.40%)

= $1,024.00

Example 2 shows that you will receive the return of your principal investment plus the final Contingent Coupon when the Final Value of the Least Performing Underlying is above its Barrier Value and Coupon Trigger even though there is a decrease in the level of the Least Performing Underlying.

Example 3: The value of the Least Performing Underlying decreases from its Initial Value to its Final Value by 42%.


Underlying	Initial Value	Final Value
INDU	1,000.00	580.00 (58% of its Initial Value)
RTY	1,000.00	900.00 (90% of its Initial Value)
XOP	$100.00	$130.00 (130% of its Initial Value)

FWP-15

INDU is the Least Performing Underlying. Because the level of INDU decreases by 42% from its Initial Value to its Final Value, the Reference Return of the Least Performing Underlying is -42.00%, calculated as follows:

Final Value of INDU – Initial Value of INDU

Initial Value of INDU

(580.00 – 1,000.00) / 1,000.00 = -42.00%

Because the Final Value of the Least Performing Underlying is less than its Coupon Trigger but greater or equal to its Barrier Value, the Final Settlement Value would be the Principal Amount.

Example 3 shows that you will receive the return of your principal investment when the Final Value of the Least Performing Underlying is at or above its Barrier Value but below its Coupon Trigger even though there is a decrease in the level of the Least Performing Underlying.

Example 4: The value of the Least Performing Underlying decreases from its Initial Value to its Final Value by 60%.


Underlying	Initial Value	Final Value
INDU	1,000.00	800.00 (80% of its Initial Value)
RTY	1,000.00	800.00 (80% of its Initial Value)
XOP	$100.00	$40.00 (40% of its Initial Value)

XOP is the Least Performing Underlying. Because the price of XOP decreases by 60% from its Initial Value to its Final Value, the Reference Return of the Least Performing Underlying is -60.00%, calculated as follows:

Final Value of XOP – Initial Value of XOP

Initial Value of XOP

($40.00 - $100.00) / $100.00 = -60.00%

Because the Final Value of the Least Performing Underlying is below its Barrier Value, the Final Settlement Value would be $400.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × (Reference Return of the Least Performing Underlying)

= $1,000 + ($1,000 × -60.00%)

= $400.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the price of the Least Performing Underlying if the Final Value of the Least Performing Underlying is below its Barrier Value. YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR NOTES.

The SPDR^® S&P^® Oil & Gas Exploration & Production ETF

The SPDR^® S&P^® Oil & Gas Exploration & Production ETF (the “XOP”) is an investment portfolio maintained and managed by SSgA Funds Management, Inc. (“SSFM”). The XOP trades on the NYSE Arca under the ticker symbol “XOP.” The inception date of the SPDR^® S&P Oil & Gas Exploration and Production ETF is June 19, 2006. Prior to January 8, 2007, the XOP was known as the SPDR^® Oil & Gas Exploration & Production ETF.

Information provided to or filed with the SEC by the SPDR^® Series Trust under the Securities Exchange Act of 1934 can be located by reference to its Central Index Key, or CIK, 1064642 through the SEC’s website at http://www.sec.gov. We have not made any independent investigation as to the accuracy or completeness of such information.

The XOP utilizes a “replication” investment approach in attempting to track the performance of the underlying index. The XOP typically invests in substantially all of the securities which comprise the underlying index in approximately the same proportions as the underlying index. XOP will normally invest at least 80% of its total assets in common stocks that comprise the underlying index. The returns of the XOP may be affected by certain management fees and other expenses, which are detailed in its prospectus.

The information above was compiled from the SPDR^® website. We have not independently investigated the accuracy of that information. Information contained in the SPDR^®website is not incorporated by reference in, and should not be considered a part of, this document.

The Underlying Index

We have derived all information contained in this document regarding the underlying index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by, SSFM.

The underlying index is an equal-weighted index that is designed to measure the performance of the oil and gas exploration and production 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 oil and gas exploration and production 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, 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:

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

2. 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.

FWP-18

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.

The graph below illustrates the daily performance of the XOP from July 16, 2009 through July 16, 2019 based on information from Bloomberg. Historical prices and past performance of this Underlying is not indicative of its future performance, and no assurance can be given as to the Official Closing Price of the XOP on any Coupon Observation Date, including the Final Valuation Date.

FWP-19

EVENTS OF DEFAULT AND ACCELERATION

If the Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Notes, the calculation agent will determine the accelerated payment due and payable in the same general manner as described in this 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 each Underlying, 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 an Underlying on that scheduled trading day, then the accelerated Final Valuation Date for that Underlying 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. For the avoidance of doubt, if no market disruption event exists with respect to an Underlying on the scheduled trading day preceding the date of acceleration, the determination of such Underlying’s Final Value will be made on such date, irrespective of the existence of a market disruption event with respect to any other Underlying occurring on such date.

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

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

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 document. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 0.625% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers.

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

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

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

We expect 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.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one approach, a Note should be treated as a contingent income-bearing pre-paid executory contract with respect to the Underlyings. 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 contingent income-bearing pre-paid executory contract with respect to the Underlyings. Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes, other characterizations and treatments are possible and the timing and character of income in respect of the Notes might differ from the treatment described herein. For example, the Notes could be treated as debt instruments that are “contingent payment debt instruments” for U.S. federal income tax purposes subject to the treatment described under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes — Contingent Notes” in the accompanying prospectus supplement.

We will not attempt to ascertain whether an Underlying or any of the entities whose stock is included in, or owned by, an Underlying, as the case may be, would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation

FWP-20

(“USRPHC”), both as defined for U.S. federal income tax purposes. If an Underlying or one or more of the entities whose stock is included in, or owned by, an Underlying, 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 Underlyings and the entities whose stock is included in, or owned by, the Underlyings and consult your tax advisor regarding the possible consequences to you if an Underlying or one or more of the entities whose stock is included in, or owned by, an Underlying, as the case may be, is or becomes a PFIC or a USRPHC.

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

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

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, Internal Revenue Service guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2021. Based on the Issuer’s determination that the 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 Underlyings 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 Underlyings 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.
