GENERAL

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

You should read this document together with the prospectus dated March 5, 2015, the prospectus supplement dated March 5, 2015 and the Stock-Linked Underlying Supplement dated March 5, 2015. If the terms of the Notes offered hereby are inconsistent with those described in the accompanying prospectus supplement, prospectus or Stock-Linked 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-6 of this pricing supplement, beginning on page S-1 of the prospectus supplement and beginning on page S-1 of the Stock-Linked Underlying Supplement, as the Notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, prospectus supplement and Stock-Linked 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 Stock-Linked 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 Stock-Linked Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

PAYMENT ON THE NOTES

Call Feature

The Notes will be automatically called if the Official Closing Price of each of the Underlyings is at or above its Initial Price on any Coupon Observation Date, up to and including September 13, 2019. If the Notes are automatically called, investors will receive on the corresponding Call Payment Date, a cash payment per $1,000 Principal Amount of Notes equal to 100% of the Principal Amount, together with the applicable Contingent Coupon.

Contingent Coupon

We will pay a quarterly Contingent Coupon payment on a Coupon Payment Date if the Official Closing Price 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 “Recipients of Interest Payments” on page S-12 in the accompanying prospectus supplement. The Contingent Coupon Rate is 17.00% per annum ($42.50 per $1,000 in Principal Amount per quarter, if payable).

Maturity

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

n If the Reference Return of the Least Performing Underlying is greater than or equal to -30.00%:

$1,000 + final Contingent Coupon

n If the Reference Return of any Underlying is less than -30.00%:

The Physical Delivery Amount in shares of the Least Performing Underlying.

If the Final Price of the Least Performing Underlying is less than its Barrier Price, you may lose up to 100% of the Principal Amount.

Calculation Agent

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

PS-5

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 Stock-Linked Underlying Supplement. Investing in the Notes is not equivalent to investing directly in any of the Underlyings. 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 pricing supplement and the accompanying prospectus, prospectus supplement and Stock-Linked Underlying Supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and Stock-Linked 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 Reference Stocks” in the Stock-Linked 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 if the Notes are not automatically called and the Final Price of the Least Performing Underlying is less than its Barrier Price, we will pay you in shares of the Least Performing Underlying. In that case, you will be exposed to the negative Reference Return on a 1-to-1 basis and the Payment at Maturity you will be entitled to receive will be less than the Principal Amount of the Notes. You may lose up to 100% of your investment at maturity.

You may not receive any Contingent Coupons.

We will not necessarily make periodic coupon payments on the Notes. If the Official Closing Price 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 Price 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.

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 Price of the Least Performing Underlying is equal to or greater than its Barrier Price, regardless of any appreciation in the prices 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 3 equity securities. 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 any 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 Underlyings. To receive any contingent coupons, each Underlying must close at or above their respective Coupon Triggers on the applicable Coupon Observation Date. In addition, if any 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 Underlyings have appreciated. Under this scenario, the payment at maturity will be less than 70% 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 or more 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 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 quarterly Coupon

PS-6

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.

If the Physical Delivery Amount will be paid on the Notes, you will be subject to the price fluctuation of the Least Performing Underlying after the Final Valuation Date.

If the Final Price of the Least Performing Underlying is less than its Barrier Price, we will deliver to you at maturity the Physical Delivery Amount in shares of the Least Performing Underlying. The value of those shares may further decrease between the Final Valuation Date and the Maturity Date, and you will incur additional losses to the extent of such decrease. In addition, there is no assurance that an active trading market will continue for shares of the Least Performing Underlying or that there will be liquidity in that trading market.

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 3 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 price 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.

PS-7

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

The amount payable on the Notes is not linked to the prices 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 Prices 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 price of any 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 decreases on that Coupon Observation Date to a price that is less than its Coupon Trigger, the Contingent Coupon will not be payable for that Coupon Observation Date. Similarly, if the Notes are not called, even if the price of the Least Performing Underlying is greater than or equal to its Barrier Price during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a price that is less than its Barrier Price, the Payment at Maturity will be less, possibly significantly less, than it would have been had the Payment at Maturity been linked to the price of the Least Performing Underlying prior to such decrease. Although the actual prices of the Underlyings on the Maturity Date or at other times during the term of the Notes may be higher than their respective prices 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 Prices of the Underlyings on the applicable Coupon Observation Dates.

Higher Contingent Coupon payments or lower Barrier Prices 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 the Underlyings. The greater the expected volatility with respect to the Underlyings on the Pricing Date, the higher the expectation as of the Pricing Date that the price of the Underlyings could close below their respective Barrier Price on the Final Valuation Date, indicating a higher expected risk of loss on the Notes. This greater expected risk will generally be reflected in a higher Contingent Coupon payment than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as a lower Barrier Price or a higher Contingent Coupon payment) than for similar securities linked to the performance of the Underlyings with a lower expected volatility as of the Pricing Date. You should therefore understand that a relatively higher Contingent Coupon payment may indicate an increased risk of loss. Further, a relatively lower Barrier Price may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of the Underlyings can change significantly over the term of the Notes. The price of the Underlyings 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 Underlyings and the potential to lose some or all of your principal at maturity.

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.

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.

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 the Least Performing Underlying relative to its Initial Price. We cannot predict the Official Closing Price 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 the Least Performing 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:

4Principal Amount:	$1,000
4Hypothetical Initial Price of the Least Performing Underlying:	$100.00*
4Hypothetical Barrier Price:	$70.00, 70% of the Initial Price
4Hypothetical Coupon Trigger:	$70.00, 70% of the Initial Price
4Contingent Coupon Rate:	17.00% per annum (4.25% for each quarter in which it is payable). If the Official Closing Price 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 $340.00 per $1,000 Principal Amount of the Notes.

* The hypothetical Initial Price of $100.00 used in the examples below has been chosen for illustrative purposes only and does not represent the actual Initial Price. The actual Initial Price of each Underlying is set forth on page PS-3 of this pricing supplement.

Summary of the Examples

	Notes Are Called on a Coupon Observation Date	Notes Are Not Called on Any Coupon Observation Date
	Example 1	Example 2	Example 3
Initial Price	$100.00	$100.00	$100.00
Barrier Price	$70.00	$70.00	$70.00
Coupon Trigger	$70.00	$70.00	$70.00
Official Closing Price / Percentage Change on the First Coupon Observation Date	$80.00/-20.00%	$65.00/-35.00%	$65.00/-35.00%
Official Closing Price / Percentage Change on the Second Coupon Observation Date	$90.00/-10.00%	$85.00/-15.00%	$65.00/-35.00%

Official Closing Price / Percentage Change on the Final Valuation Date	N/A	$75.00/-25.00%	$60.00/-40.00%
Contingent Coupon Payment Amounts over the Term of the Notes	3 x $42.50 = $127.50	5 x $42.50 = $212.50	0 x $42.50 = $0.00
Principal Amount Payment if Notes are Called	$1,000	N/A	N/A
Principal Amount Payment at Maturity	N/A	$1,000	$1,000 + $1,000 x -40.00% = $600.00*
Return of the Notes	12.75%	21.25%	-40.00%

** If the Final Price of the Least Performing Underlying is less than its Barrier Price, we will pay you 10 shares of the Least Performing Underlying. The value of the 10 shares is based on the Final Price of the Least Performing Underlying.

PS-10

Example 1—The Official Closing Price of each Underlying on the third Coupon Observation Date is greater than or equal to its Initial Price and each Underlying closed at or above its Coupon Trigger on the two prior Coupon Observation Dates.

Underlying	Initial Price	Final Price
BA	$100.00	$130.00 (130.00% of Initial Price)
JPM	$100.00	$120.00 (120.00% of Initial Price)
NFLX	$100.00	$105.00 (105.00% of Initial Price)

Return of the Least Performing Underlying:	105.00%
Principal Amount plus Contingent Coupon:	$1,042.50

Because the Official Closing Price of each Underlying on the third Coupon Observation Date is at or above its Initial Price, the Notes will be called and you will receive $1,042.50 per Note, reflecting the Principal Amount plus the Contingent Coupon. When added to the Contingent Coupon payments of $85.00 received in respect of the prior Coupon Observation Dates, we will have paid you a total of $1,127.50 per Note, resulting in a 12.75% return on the Notes.

Example 2— The Notes are not called, the Final Price of the Least Performing Underlying is greater than or equal to its Barrier Price, and the Least Performing Underlying closed at or above its Coupon Trigger on four of the seven Coupon Observation Dates prior to the Final Valuation Date.

Underlying	Initial Price	Final Price
BA	$100.00	$75.00 (75.00% of Initial Price)
JPM	$100.00	$80.00 (80.00% of Initial Price)
NFLX	$100.00	$90.00 (90.00% of Initial Price)

The Boeing Company (“BA”) is the Least Performing Underlying.

Reference Return of the Least Performing Underlying:	75.00%
Final Settlement Value:	$1,042.50

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

Payment at Maturity = $1,000 + $42.50 = $1,042.50

When added to each of the previous four Contingent Coupon payments of $42.50 received in respect of prior Coupon Observation Dates, we will have paid you a total of $1,212.50 per Note, resulting in a 21.25% return on the Notes.

PS-11

Example 3— The Notes are not called, the Final Price of the Least Performing Underlying is less than its Barrier Price, and the Least Performing Underlying did not close at or above its Coupon Trigger on any Coupon Observation Date.

Underlying	Initial Price	Final Price
BA	$100.00	$60.00 (60.00% of Initial Price)
JPM	$100.00	$80.00 (80.00% of Initial Price)
NFLX	$100.00	$90.00 (90.00%  of Initial Price)

The Boeing Company (“BA”) is the Least Performing Underlying.

Reference Return of the Least Performing Underlying:	60.00%
Final Settlement Value:	$600.00

Because the Final Price of the Least Performing Underlying is less than its Barrier Price, you will receive $600.00 per $1,000 in Principal Amount, calculated as follows:

Final Price – Initial Price
Initial Price

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

Final Settlement Value = Principal Amount/Initial Price of the Least Performing Underlying.

= $1,000/$100.00 = 10 shares of the Least Performing Underlying

The value of these shares based on the Final Price of the Least Performing Underlying is $600.00. Because there was no Contingent Coupon payable in respect of the prior Coupon Observation Dates, we will pay you a total of $600.00, resulting in a -40.00% return on the Notes. Because the Reference Return is less than -30.00%, you would receive the Physical Delivery Amount, or 10 shares of the Least Performing Underlying per $1,000 Principal Amount. As of the Valuation Date, these shares would have a value of $600.00 (10 shares multiplied by the Final Price of $60.00). Under these circumstances, the value of the Physical Delivery Amount would represent a loss of -40.00% of your principal amount.

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

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 pricing supplement 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.

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 this pricing supplement, for distribution to other registered broker-dealers or will offer the Notes directly to investors. HSBC Securities (USA) Inc. will offer the Notes at the price to public set forth on the cover page of this pricing supplement. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 2.00% per $1,000 Principal Amount of Notes and structuring fees of 0.25% per $1,000 Principal Amount of the Notes in connection with the distribution of the Notes to other registered broker-dealers. In no case will the sum of the underwriting discount and structuring fees exceed 2.25%.

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 pricing supplement 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.

Delivery of the Notes will be made against payment for the Notes on the original issue date set forth on the cover page of this document, which is more than two business days following the pricing date. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than two business days prior to the original issue date will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-59 in the prospectus supplement.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one approach, a Note should be treated as a 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, Morrison & Foerster 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 Underlying 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 any Underlying 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 consult your tax advisor regarding the possible consequences to you if any Underlying 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 on the receipt of cash upon maturity or an earlier sale 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. If upon maturity of the Notes, you receive shares of the Least Performing Underlying (the “Underlying Shares”) and cash in lieu of any fractional Underlying Share, you should generally recognize capital gain or loss equal to the difference between the amount of cash received in lieu of any fractional Underlying Share and the pro rata portion of your tax basis in the Notes that is allocable to such fractional Underlying Share, based on the amount of cash received and the fair market value of the Underlying Shares received. Although no assurances can be provided in this regard, you may generally expect not to recognize any gain or loss with respect to any Underlying Shares received. You should generally have a basis in the Underlying Shares equal to your tax basis in the Notes, other than any amount allocated to a fractional Underlying Share. The holding period for such Underlying Shares should start on the day after receipt. 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, 2019. 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 an Underlying 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 an Underlying 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.

Foreign Account Tax Compliance Act. The Internal Revenue Service 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 Notes 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 Note, please see the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.
