GENERAL

This document relates to the offering of Notes. The purchaser of a Note will acquire a senior unsecured debt security of HSBC USA Inc.

You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-7 of this document, beginning on page S-1 of the prospectus supplement and beginning on page S-1 of the Equity Index Underlying Supplement, as the Notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

PAYMENT ON THE NOTES

Call Feature

If the Official Closing Level of each Underlying is at or above its Initial Level on any Call Observation Date the Notes will be automatically called, and you will receive a cash payment, per $1,000 Principal Amount of Notes, equal to the Principal Amount plus the applicable Contingent Coupon on the corresponding Call Payment Date.

Contingent Coupon

We will pay a quarterly Contingent Coupon payment on a Coupon Payment Date if the Official Closing Level of each Underlying on the applicable Coupon Observation Date is greater than or equal to its Coupon Trigger. Otherwise, no coupon will be paid on such Coupon Payment Date. For information regarding the record dates applicable to the Contingent Coupons payable on the Notes, please see the section entitled “Description of Notes—Interest and Principal Payments—Recipients of Interest Payments” beginning on page S-14 in the accompanying prospectus supplement. The Contingent Coupon Rate is 12.00% per annum (or $30.00 per $1,000 in Principal Amount per quarter), if payable.

Payment at Maturity

Unless the Notes are called, on the Maturity Date and for each $1,000 Principal Amount of Notes, you will receive a cash payment equal to the Final Settlement Value determined as follows:

nIf the Reference Return of each Underlying is greater than or equal to -25.00%:

$1,000 + final Contingent Coupon

nIf the Reference Return of each Underlying is less than -25.00% but greater than or equal to -40.00%:

$1,000

nIf the Reference Return of any Underlying is less than -40.00%:

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

If the Notes are not called prior to maturity and the Final Level of the Least Performing Underlying is less than its Barrier Level, you may lose up to 100% of the Principal Amount. Even with any Contingent Coupons, your return on the Notes will be negative in this case.

Calculation Agent

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

Reference Sponsors

INVESTOR SUITABILITY

The Notes may be suitable for you if:

The Notes may not be suitable for you if:

4You believe that the Official Closing Level of each Underlying will be at or above its Coupon Trigger on most or all of the Coupon Observation Dates, and the Final Level of the Least Performing Underlying will be at or above its Barrier Level. 4You seek a quarterly Contingent Coupon, based on the performance of the Underlyings, that will be paid at the Contingent Coupon Rate of 12.00% per annum if the Official Closing Level of each Underlying is greater than or equal to its Coupon Trigger on the applicable Coupon Observation Date. 4You are willing to invest in the Notes based on the fact that your maximum potential return is any Contingent Coupons payable on the Notes. 4You do not seek an investment that provides an opportunity to participate in the appreciation of the Underlyings. 4You are willing to make an investment that is exposed to the potential downside performance of the Underlyings on a 1-to-1 basis if the Reference Return of each Underlying is less than -40.00%. 4You are willing to lose up to 100% of the Principal Amount. 4You are willing to hold the Notes that will be automatically called on any Call Observation Date on which the Official Closing Level of each Underlying is at or above its Initial Level, or you are otherwise willing to hold the Notes to maturity. 4You are willing to guaranteed interest payments on the Notes, and forgo dividends or other distributions paid on the stocks included in either Underlying. 4You do not seek an investment for which there will be an active secondary market. 4You 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. 4You are comfortable with the creditworthiness of HSBC, as Issuer of the Notes.

4You believe that the Official Closing Level of at least one Underlying will be below its Coupon Trigger on most or all the Coupon Observation Dates, including the Final Valuation Date, and the Final Level of the Least Performing Underlying will be below its Barrier Level. 4You believe that the Contingent Coupon, if any, will not provide you with your desired return. 4You are unwilling to invest in the Notes based on the fact that your maximum potential return is any Contingent Coupons payable on the Notes. 4You seek an investment that provides an opportunity to participate in the appreciation of the Underlyings. 4You are unwilling to make an investment that is exposed to the potential downside performance of the Underlyings on a 1-to-1 basis if the Reference Return of the Least Performing Underlying is less than -40.00% 4You seek an investment that provides full return of principal at maturity. 4You are unable or unwilling to hold the Notes that will be automatically called on any Call Observation Date on which the Official Closing Level of each Underlying is at or above its Initial Level, or you are otherwise unable or unwilling to hold the Notes to maturity. 4You prefer to receive guaranteed periodic interest payments on the Notes, or the dividends or other distributions paid on the stocks included in either Underlying. 4You seek an investment for which there will be an active secondary market. 4You 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. 4You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Notes.

PS-6

RISK FACTORS

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

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

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

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

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

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 automatically called prior to maturity and the Final Level of the Least Performing Underlying is less than its Barrier Level. 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 -40.00%.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 Level of each Underlying on a Coupon Observation Date is less than its Coupon Trigger, we will not pay you the Contingent Coupon applicable to that Coupon Observation Date. If on each of the Coupon Observation Dates, the Official Closing Level 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 level of the Underlyings.

For each $1,000 in principal amount of the Notes, you will receive $1,000 at maturity plus the final Contingent Coupon if the Final Level of the Least Performing Underlying is equal to or greater than its Coupon Trigger, regardless of any appreciation in the levels of the Underlyings, which may be significant. Accordingly, the return on the Notes may be significantly less than the return on a direct investment in the Underlyings during the term of the Notes.

You are exposed to the market risk of all of the Underlyings, with respect to both the Contingent Coupons, if any, and the payment at maturity, if any.

Your return on the Notes is not linked to a basket consisting of the 2 equity indices. Rather, it will be contingent upon the independent performance of each Underlying. Unlike an instrument with a return linked to a basket of underlying assets, in which risk is potentially mitigated and diversified among all the components of the basket, you will be exposed to the risks related to all of the Underlyings. Poor performance by either Underlying over the term of the Notes may negatively affect your return and will not be offset or mitigated by any positive performance by the other Underlying. To receive any contingent coupons, each Underlying must close at or above its respective Coupon Trigger on the applicable Coupon Observation Date. In addition, if either Underlying has decreased to below its respective Barrier Price as of the Final Valuation Date, you will be fully exposed to the decrease in the Least Performing Underlying on a 1 to 1 basis, even if the other Underlying has appreciated. Under this scenario, the payment at maturity will be less than 60.00% of the Principal Amount and could be zero. Accordingly, your investment is subject to the market risk of each of the Underlyings.

Because the Notes are linked to the performance of the Least Performing Underlying, you are exposed to greater risks of receiving no Contingent Coupons and sustaining a significant loss on your investment than if the Notes were linked to just one Underlying. 

The risk that you will not receive any Contingent Coupons, or that you will suffer a significant loss on your investment, is greater if you invest in the Notes as opposed to substantially similar securities that are linked to the performance of just one Underlying. With 3 Underlyings, it is more likely that one of the Underlyings will close below its respective Coupon Trigger on any Coupon Observation Date (including the Final Valuation Date) and below its respective Barrier Price on the Final Valuation Date, than if the Notes were linked to

PS-7

only one Underlying. Therefore, it is more likely that you will not receive any Contingent Coupons, and that you will suffer a significant loss on your investment. In addition, because each Underlying must close above its initial price on a Call Observation Date in order for the Notes to be called prior to maturity, the Notes are less likely to be called than if the Notes were linked to just one Underlying.

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 payments to be made on the Notes, including any Contingent Coupon 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 automatically called prior to the Maturity Date.

If the Notes are automatically called early, the holding period over which you may receive coupon payments 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 automatically called prior to the Maturity Date.

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

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

The Estimated Initial Value of the Notes, which was determined by us on the Pricing Date, is 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 was calculated by us on the Pricing Date and is less than the price to public. The Estimated Initial Value reflects 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 pay 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 determined 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 levels 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

PS-8

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 amount payable on the Notes is not linked to the levels 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 Levels 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 level 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 that is less than its Coupon Trigger, the Contingent Coupon will not be payable for the relevant quarterly period. Similarly, if the Notes are not called, even if the level of the Least Performing Underlying is greater than or equal to its Barrier Level during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a level that is less than the Barrier Level, 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 of the Least Performing Underlying prior to such decrease. Although the actual levels of the Underlyings on the Maturity Date or at other times during the term of the Notes may be higher than their respective levels 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 Levels of the Underlyings on the applicable Coupon Observation Dates.

Changes that affect an Underlying may affect the level of that Underlying and the market value of the Notes and the amount you will receive on the Notes.

The policies of the index sponsor of an Underlying concerning additions, deletions and substitutions of the stocks included in that Underlying, and the manner in which the index sponsor takes account of certain changes affecting those stocks, may affect the level of that Underlying. The policies of the index sponsor with respect to the calculation of an Underlying could also affect the level of that Underlying. The index sponsor may discontinue or suspend calculation or dissemination of an Underlying. Any such actions could affect the level of an Underlying and the value of the Notes.

Owning the Notes is not the same as owning the stocks included in either Underlying.

The return on your Notes may not reflect the return you would realize if you actually owned stocks included in either of the Underlyings. 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 the stocks included in either Underlying.

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 level of the SX7E depends upon the stocks of companies located within the Eurozone, and thus involve risks associated with the home countries of those non-U.S. companies, some of which are and have been experiencing economic stress. 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 SX7E and, as a result, the value of the Notes.

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

Although the equity securities that comprise the SX7E are traded in euro, 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 euro. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the level of the SX7E, 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 pricing supplement.

A limited number of stocks included in the SX7E may affect its level, and the SX7E is not necessarily representative of the financial services industry.

As of May 31, 2019 the top five stocks in the SX7E constituted 57.43% of the total weight of the SX7E, and the top 10 stocks included in the SX7E constituted 79.02% of the total weight of the SX7E. Any reduction in the market price of those stocks is likely to have a substantial adverse impact on the level of the SX7E and the value of the Notes. While the stocks included in the SX7E are common stocks of companies generally considered to be involved in various segments of the European financial services industry, the stocks included in the SX7E and the SX7E itself may not necessarily follow the price movements of the entire industry. If the stocks included in the SX7E decline in value, the SX7E will also decline in value, even if common stock prices of other companies in the European financial services industry generally increase in value.

ILLUSTRATIVE EXAMPLES

The following table and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the level of either Underlying relative to its Initial Level. We cannot predict the Official Closing Level of either Underlying 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 either Underlying 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 either 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. 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 are based on the following terms:

4	Principal Amount:	$1,000
4	Hypothetical Initial Level	1,000.00*
4	Hypothetical Barrier Level:	600.00, 60.00% of the Initial Level
4	Hypothetical Coupon Trigger:	750.00, 75.00% of the Initial Level
4	Contingent Coupon Rate:	12.00% per annum (3.00% for each quarter in which it is payable). If the Official Closing Level 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 $1,200.00 per $1,000 Principal Amount of the Notes.

* The hypothetical Initial Level of 1,000.00 used in the examples below has been chosen for illustrative purposes only and does not represent the actual Initial Level of either Underlying. The actual Initial Level of each Underlying is set forth on page PS-3 of this document.

Summary of the Examples

The following examples assume that (i) the Notes are not called during the first 8 years and (ii) that none of the Underlyings fell below their respective Coupon Triggers on twenty of the twenty-eight Coupon Observation Dates during that period, and as a result an investor received twenty Contingent Coupons with respect to those Coupon Observation Dates, totalling $600.00 per $1,000 in Principal Amount of the Notes.

	Notes Are Called on a Call Observation Date	Notes Are Not Called on Any Call Observation Date
	Example 1	Example 2	Example 3
Initial Level of each Underlying	1,000.00	1,000.00	1,000.00
Barrier Level of each Underlying	600.00	600.00	600.00
Coupon Trigger of each Underlying	750.00	750.00	750.00
Official Closing Level / Percentage Change of the Least Performing Underlying on the:
Twenty-ninth Coupon Observation Date	825.00/-17.50%	675.00/-32.50%	700.00/-30.00%
Thirtieth Coupon Observation Date	900.00/-10.00%	720.00/-28.00%	675.00/-32.50%
Thirty-first Coupon Observation Date	1,050.00/5.00%	825.00/-17.50%	720.00/-28.00%
Thirty-second Coupon Observation Date	N/A	900.00/-10.00%	700.00/-30.00%
Thirty-third Coupon Observation Date	N/A	720.00/-28.00%	675.00/-32.50%
Thirty-fourth Coupon Observation Date	N/A	675.00/-32.50%	700.00/-30.00%
Thirty-fifth Coupon Observation Date	N/A	700.00/-30.00%	720.00/-28.00%
Thirty-six Coupon Observation Date	N/A	720.00/-28.00%	700.00/-30.00%
Thirty-seven Coupon Observation Date	N/A	700.00/-30.00%	700.00/-30.00%
Thirty-eight Coupon Observation Date	N/A	825.00/-17.50%	675.00/-32.50%
Thirty-ninth Coupon Observation Date	N/A	900.00/-10.00%	525.00/-47.50%
Final Valuation Date	N/A	850.00/-15.00%	500.00/-50.00%
Contingent Coupon Payment Amounts Prior to Maturity or Call	22 x $30.00 = $660.00	24 x $30.00 = $720.00	20 x $30.00 = $600.00
Payment if Notes are Called	$1,030.00	N/A	N/A
Payment at Maturity	N/A	$1,030.00	$1,000 + ($1,000 x -50.00%) = $500.00
Return of the Notes	69.00%	75.00%	10.00%

PS-11

Example 1—The Official Closing Level of each Underlying on the thirty-first Coupon Observation Date is greater than or equal to its Initial Level and each Underlying closed at or above its Coupon Trigger (but below its Initial Level) on twenty-two of the Coupon Observation Dates prior to the Notes being automatically called.

Underlying	Initial Level	Final Level
INDU	1,000.00	1,300.00 (130.00% of Initial Level)
SX7E	1,000.00	1,200.00 (120.00% of Initial Level)

Payment Upon a Call: $1,030.00

Because the Official Closing Level of each Underlying on the thirty-first Coupon Observation Date is at or above its Initial Level, the Notes will be called and you will receive $1,030.00 per Note, reflecting the Principal Amount plus the Contingent Coupon. When added to the Contingent Coupon payments of $660.00 received in respect of the prior Coupon Observation Dates, we will have paid you a total of $1,690.00 per Note, resulting in a 69.00% return on the Notes. No extra payment will be made on account of each Underlying closing above its respective Initial Level.

Example 2— The Notes are not called, the Final Level of the Least Performing Underlying is greater than or equal to its Barrier Level, and each Underlying closed at or above its Coupon Trigger (but below its Initial Level) on twenty-four of the Coupon Observation Dates prior to the Final Valuation Date.

Underlying	Initial Level	Final Level
INDU	1,000.00	900.00 (90.00% of Initial Level)
SX7E	1,000.00	850.00 (85.00% of Initial Level)

SX7E is the Least Performing Underlying.

Reference Return of the Least Performing Underlying:	-15.00%
Payment at Maturity:	$1,030.00

Because the Final Level of the Least Performing Underlying is greater than or equal to its Coupon Trigger, you will receive $1,000 per $1,000 in Principal Amount plus the final Contingent Coupon, calculated as follows:

Final Settlement Value = $1,000 + $30.00 = $1,030.00

When added to the Contingent Coupon payments of $720.00 received in respect of the prior Coupon Observation Dates, we will have paid you a total of $1,750.00 per Note, resulting in a 75.00% return on the Notes.

PS-12

Example 3—The Notes are not called, the Final Level of the Least Performing Underlying is less than its Barrier Level, and the Underlyings did not all close at or above their respective Coupon Triggers on any Coupon Observation Date for the last two years prior to maturity.

Underlying	Initial Level	Final Level
INDU	1,000.00	500.00 (50.00% of Initial Level)
SX7E	1,000.00	700.00 (70.00% of Initial Level)

INDU is the Least Performing Underlying.

Reference Return of the Least Performing Underlying:	-50.00%
Payment at Maturity:	$500.00

Because the Final Level of the Least Performing Underlying is less than its Barrier Level, you will receive $500.00 per $1,000 in Principal Amount, calculated as follows:

Final Settlement Value = $1,000 + ($1,000 x -50.00%) = $500.00

Because you received 20 coupon payments totaling $600.00 in the first 8 years, we will pay you a total of $1,100.00, resulting in a 10.00% return on the Notes.

If the Notes are not called and the Final Level of the Least Performing Underlying is less than its Barrier Level, you will be exposed to any decrease in the level of the Least Performing Underlying on a 1:1 basis and could lose up to 100% of your principal at maturity.

INFORMATION RELATING TO THE UNDERLYINGS

Description of the INDU   The INDU is a price-weighted index compromised of 30 blue chip stocks considered to be the leaders in their industry. It is intended to be a measure of the entire U.S. market, covering a diverse set of industries such as financial services, technology, retail, entertainment and consumer goods, but excluding the transportation and utilities industries.   For more information about the Reference Asset, see “Dow Jones Industrial Average^®” on page S-25 of the accompanying Equity Index Underlying Supplement. Historical Performance of the INDU   The following graph sets forth the historical performance of the INDU based on the daily historical closing levels from June 1, 2009 through June 25, 2019. We obtained the closing levels below from the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service.  

The historical levels of the INDU should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the INDU on any Coupon Observation Date, including the Final Valuation Date.

Description of the SX7E

We have derived all information contained in this term sheet regarding the SX7E, 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, STOXX Limited. STOXX Limited is under no obligation to continue to publish, and may discontinue or suspend the publication of the SX7E at any time.

STOXX Limited Publishes the SX7E

The SX7E was created by STOXX Limited, which is owned by Deutsche Börse AG and SIX Group AG. Publication of the SX7E began on June 15, 1998, based on an initial index value of 100 at December 31, 1991. The SX7E is reported daily on the Bloomberg Professional^® service under the symbol “SX7E” and on the STOXX Limited website. Information contained in the STOXX Limited website is not incorporated by reference in, and should not be considered a part of, this document.

Index Composition and Maintenance

The SX7E is one of the 19 EURO STOXX^® Supersector indices that compose the STOXX^® Europe 600 Index. The STOXX^® Europe 600 Index contains the 600 largest stocks traded on the major exchanges of 18 European countries and are organized into the following 19 Supersectors: automobiles & parts; banks; basic resources; chemicals; construction & materials; financial services; food & beverage; health care; industrial goods & services; insurance; media; oil & gas; personal & household goods; real estate; retail; technology; telecommunications; and utilities. The SX7E includes companies in the banks supersector, which tracks companies providing a broad range of financial services, including retail banking, loans and money transmissions. The SX7E currently includes 26 stocks.

The SX7E is weighted by free float market capitalization. Each component’s weight is capped at 30% of the SX7E’s total free float market capitalization. Free float weights are reviewed quarterly.

The composition of each of the EURO STOXX^® Supersector indices is reviewed quarterly, based on the closing stock data on the last trading day of the month following the implementation of the last quarterly index review. The component stocks are announced on the fourth Tuesday of the month immediately prior to the review implementation month. Changes to the component stocks are implemented on the third Friday in each of March, June, September and December and are effective the following trading day. All index components will be adjusted for corporate actions.

As of May 31, 2019, the top 10 companies included in the SX7E were as follows:

COMPANY	Weight (%)
BCO SANTANDER	17.43
BNP PARIBAS	12.80
ING GRP	10.25
INTESA SANPAOLO	8.82
BCO BILBAO VIZCAYA ARGENTARIA	8.13
UNICREDIT	5.86
GRP SOCIETE GENERALE	4.93
KBC GRP	4.16
CREDIT AGRICOLE	3.48
DEUTSCHE BANK	3.16

Index Calculation

The SX7E is calculated with the “Laspeyres formula”, which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the index value can be expressed as follows:

Index =	free float market capitalization of the SX7E
	divisor of the SX7E

The “free float market capitalization of the SX7E” is equal to the sum of the product of the price, number of shares, free float factor and weighting cap factor for each component stock as of the time the SX7E is being calculated.

The SX7E is also subject to a divisor, which is adjusted to maintain the continuity of SX7E values despite changes due to corporate actions.

License Agreement

HSBC or one of its affiliates has entered into a nonexclusive license agreement providing for the license to it, in exchange for a fee, of the right to use certain indices owned and published by STOXX Limited in connection with some products, including the Notes.

STOXX and its licensors (the “Licensors”) have no relationship to the HSBC Bank USA, National Association, other than the licensing of the SX7E and the related trademarks for use in connection with the Notes.

PS-15

STOXX and its Licensors do not:

· Sponsor, endorse, sell or promote the Notes.

· Recommend that any person invest in the Notes or any other securities.

· Have any responsibility or liability for or make any decisions about the timing, amount or pricing of the Notes.

· Have any responsibility or liability for the administration, management or marketing of the Notes.

· Consider the needs of the Notes or the owners of the Notes in determining, composing or calculating the SX7E or have any obligation to do so.

STOXX and its Licensors will not have any liability in connection with the Notes. Specifically,

· STOXX and its Licensors do not make any warranty, express or implied and disclaim any and all warranty about:

· The results to be obtained by the Notes, the owner of the Notes or any other person in connection with the use of the SX7E and the data included in the SX7E;

· The accuracy or completeness of the SX7E and its data;

· The merchantability and the fitness for a particular purpose or use of the SX7E and its data;

· STOXX and its Licensors will have no liability for any errors, omissions or interruptions in the SX7E or its data;

· Under no circumstances will STOXX or its Licensors be liable for any lost profits or indirect, punitive, special or consequential damages or losses, even if STOXX or its Licensors knows that they might occur.

The licensing agreement between HSBC or one of its affiliates and STOXX is solely for their benefit and not for the benefit of the owners of the Notes or any other third parties.

Historical Performance of the SX7E

The following graph sets forth the historical performance of the SX7E based on the daily historical closing levels from June 1, 2009 through May 28, 2019. We obtained the closing levels below from the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service.

 

The historical levels of the SX7E should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the SX7E on any Coupon Observation Date, including the Final Valuation Date.

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 Coupon Observation Date and the 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 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 following the postponed accelerated Final Valuation Date. For the avoidance of doubt, if no market disruption event exists with respect to an Underlying on the scheduled trading day preceding the date of acceleration, the determination of such Underlying’s Final Level will be made on such date, irrespective of the existence of a market disruption event with respect to any other Underlying occurring on such a 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.

PS-16

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 this document, for distribution to other registered broker-dealers, or will offer the Notes directly to investors. HSBC Securities (USA) Inc. has offered 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 5.00% per $1,000 Principal Amount of Notes 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 this document 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.

Delivery of the Notes will be made against payment for the Notes on 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 any of the entities whose stock is included in the Underlyings would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the Underlyings were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in the Underlyings and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Underlyings is or becomes a PFIC or a USRPHC.

U.S. Holders. Please see the discussion under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain 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.

PS-17

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.

VALIDITY OF THE NOTES
