GENERAL

This pricing supplement relates to an offering of securities linked to the Reference Asset. The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. Although the offering of securities relates to the Reference Asset, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the Reference Asset or any component security included in the Reference Asset or as to the suitability of an investment in the securities.

You should read this document together with the prospectus dated March 5, 2015, the prospectus supplement dated March 5, 2015 and the Equity Index Underlying Supplement dated March 5, 2015. If the terms of the securities offered hereby are inconsistent with those described in the accompanying prospectus, prospectus supplement, or Equity Index Underlying Supplement, the terms described in this pricing supplement shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-5 of this pricing supplement, page S-1 of the prospectus supplement and page S-2 of the Equity Index Underlying Supplement, as the securities involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, prospectus supplement and Equity Index Underlying Supplement) with the SEC for the offering to which this pricing supplement relates. Before you invest, you should read the prospectus, prospectus supplement and Equity Index Underlying Supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering. You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov. Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and Equity Index Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

PAYMENT AT MATURITY

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

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

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

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

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

$1,000 + [$1,000 × (Reference Return + 15%)].

Under these circumstances, you will lose 1% of the Principal Amount of your securities for each percentage point that the Reference Return is below the Buffer Level. For example, if the Reference Return is -30%, you will suffer a 15% loss and receive 85% of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the Reference Return is less than the Buffer Level, you will lose some or a significant portion (up to 85%) of your investment.

PS-3

Interest

The securities will not pay interest.

Calculation Agent

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

Reference Sponsor

S&P Dow Jones Indices LLC, a division of S&P Global, is the reference sponsor.

INVESTOR SUITABILITY

The securities may be suitable for you if:

You seek an investment with a return linked to the potential positive performance of the Reference Asset and you believe the level of the Reference Asset will increase over the term of the securities.

You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is below the Buffer Level of -15%.

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

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

You do not seek current income from your investment.

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

You are willing to hold the securities to maturity.

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

The securities may not be suitable for you if:

You believe the Reference Return will be negative or that the Reference Return will not be sufficiently positive to provide you with your desired return.

You are unwilling to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the Reference Return is below the Buffer Level of -15%.

You seek an investment that provides full return of principal.

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

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

You seek current income from your investment.

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

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

PS-4

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page S-2 of the accompanying Equity Index Underlying Supplement. Investing in the securities is not equivalent to investing directly in any of the stocks included in the Reference Asset. You should understand the risks of investing in the securities and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the securities in light of your particular financial circumstances and the information set forth in this pricing supplement 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 securities described in the following sections:

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

“— General Risks Related to 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.

Your investment in the securities may result in a loss.

You will be exposed to the decline in the Final Level from the Initial Level beyond the Buffer Level of -15%. Accordingly, if the Reference Return is less than the Buffer Level of -15%, your Payment at Maturity will be less than the Principal Amount of your securities. You will lose some or a significant portion (up to 85%) of your investment at maturity if the Reference Return is less than the Buffer Level.

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

The Final Level will be based on the Official Closing Level of the Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the level of the Reference Asset appreciates during the term of the securities other than on the Final Valuation Date but then decreases on the Final Valuation Date to a level that is less than the Initial Level, the Payment at Maturity may be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the level of the Reference Asset prior to such decrease. Although the actual level of the Reference Asset on the Maturity Date or at other times during the term of the securities may be higher than the Final Level, the Payment at Maturity will be based solely on the Official Closing Level of the Reference Asset on the Final Valuation Date.

Credit risk of HSBC USA Inc.

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

The securities will not bear interest.

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

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

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

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

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

The Estimated Initial Value of the securities, 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 securities in the secondary market, if any.

The Estimated Initial Value of the securities 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-

PS-5

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

The price of your securities in the secondary market, if any, immediately after the Pricing Date 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 securities and the costs associated with structuring and hedging our obligations under the securities. If you were to sell your securities in the secondary market, if any, the price you would receive for your securities may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Reference Asset and changes in market conditions, and cannot be predicted with accuracy. The securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the securities to maturity. Any sale of the securities prior to maturity could result in a loss to you.

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

Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the securities in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed the Estimated Initial Value on the Pricing Date for a temporary period expected to be approximately 7 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 securities and other costs in connection with the securities that we will no longer expect to incur over the term of the securities. 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 securities and any agreement we may have with the distributors of the securities. 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 securities based on changes in market conditions and other factors that cannot be predicted.

The securities lack liquidity.

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

Potential conflicts of interest may exist.

HSBC and its affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities. We will not have any obligation to consider your interests as a holder of the securities in taking any action that might affect the value of your securities.

Uncertain tax treatment.

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

PS-6

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 the Reference Asset relative to its Initial Level. We cannot predict the Final Level. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events, and the hypothetical Initial Level used in the table and examples below is not the actual Initial Level. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset or the return on your securities. The Final Settlement Value may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including such a security issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Payment at Maturity on a $1,000 investment in the securities for a hypothetical range of Reference Returns from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Securities” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount to $1,000. The potential returns described here assume that your securities are held to maturity. You should consider carefully whether the securities are suitable to your investment goals. The following table and examples are based on the following terms:

4	Principal Amount:	$1,000

4	Hypothetical Initial Level:	2,000.00

4	Upside Participation Rate:	100%

4	Buffer Level:	-15%

The actual Initial Level is set forth on page PS-2 of this pricing supplement.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Securities
4,000.00	100.00%	$2,000.00	100.00%

PS-7

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

Example 1: The level of the Reference Asset increases from the Initial Level of 2,000.00 to a Final Level of 2,200.00.


Reference Return:	10.00%
Final Settlement Value:	$1,100.00

Because the Reference Return is positive, the Final Settlement Value would be $1,100.00 per $1,000 Principal Amount, calculated as follows:

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

= $1,000 + ($1,000 × 10.00% × 100%)

= $1,100.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by the Upside Participation Rate of 100% when the Reference Asset appreciates.

Example 2: The level of the Reference Asset decreases from the Initial Level of 2,000.00 to a Final Level of 1,900.00.


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

Because the Reference Return is less than zero but greater than the Buffer Level of -15%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 3: The level of the Reference Asset decreases from the Initial Level of 2,000.00 to a Final Level of 1,200.00


Reference Return:	-40.00%
Final Settlement Value:	$750.00

Because the Reference Return is less than the Buffer Level of -15%, the Final Settlement Value would be $750.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 15%)]

= $1,000 + [$1,000 × (-40.00% + 15%)]

= $750.00

Example 3 shows that you are exposed on a 1-to-1 basis to declines in the level of the Reference Asset beyond the Buffer Level of -15%. You will lose some or a significant portion (up to 85%) of your investment.

DESCRIPTION OF THE REFERENCE ASSET

S&P 500^® Index

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

The top 5 industry groups by market capitalization as of April 28, 2017 were: Information Technology, Financials, Health Care, Consumer Discretionary and Industrials.

For more information about the Reference Asset, see “S&P 500^® Index” on page S-44 of the accompanying Equity Index Underlying Supplement.

Historical Performance of the Reference Asset

The following graph sets forth the historical performance of the Reference Asset based on the daily historical closing levels from January 1, 2008 through May 25, 2017. We obtained the closing levels below from the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service.

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

EVENTS OF DEFAULT AND ACCELERATION

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

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

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

U.S. FEDERAL INCOME TAX CONSIDERATIONS

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

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

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

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, U.S. Treasury regulations provide 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, 2018. Based on the Issuer’s determination that the securities are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the securities. However, it is possible that the securities could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Asset or the securities, and following such occurrence the securities could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the Reference Asset or the securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the securities and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

Additionally, the IRS has announced that withholding under the Foreign Account Tax Compliance Act (as discussed in the accompanying prospectus supplement) on payments of gross proceeds from a sale, exchange, redemption or other disposition of the securities will only apply to dispositions after December 31, 2018.

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