The Buffered Market Participation Securities ^TM(each a “security” and collectively the “securities") offered hereunder will not be listed on any U.S. securities exchange or automated quotation system. The securities will not bear interest.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the securities or passed upon the accuracy or the adequacy of this document, the accompanying prospectus, prospectus supplement or ETF Underlying Supplement. Any representation to the contrary is a criminal offense. We have appointed HSBC Securities (USA) Inc., an affiliate of ours, as the agent for the sale of the securities. HSBC Securities (USA) Inc. will purchase the securities from us for distribution to other registered broker-dealers or will offer the securities directly to investors. In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions in any securities after their initial sale. Unless we or our agent inform you otherwise in the confirmation of sale, the pricing supplement to which this free writing prospectus relates is being used in a market-making transaction. See “Supplemental Plan of Distribution (Conflicts of Interest)” on page FWP-19 of this free writing prospectus.

Investment in the securities involves certain risks. You should refer to “Risk Factors” beginning on page FWP-8 of this document, page S-1 of the accompanying prospectus supplement and page S-1 of the accompanying ETF Underlying Supplement.

The Estimated Initial Value of the securities on the Pricing Date is expected to be between $950.00 and $980.00 per security, for each of the securities, which will be less than the price to public. The market value of the securities at any time will reflect many factors and cannot be predicted with accuracy. See “Estimated Initial Value” on page FWP-5 and “Risk Factors” beginning on page FWP-8 of this document for additional information.

This free writing prospectus relates to three separate offerings of Buffered Market Participation Securities^TM by HSBC USA Inc., each linked to the performance of a different Reference Asset as indicated below.

⁽²⁾Subject to adjustment as described under “Additional Terms of the Notes” in the accompanying ETF Underlying Supplement.

The securities are designed for investors who believe the relevant Reference Asset will appreciate over the term of the securities. If the relevant Reference Return is below the Buffer Percentage, then the securities are subject to a 1:1 exposure to any potential decline of the relevant Reference Asset beyond the Buffer Percentage of -10%.

If the relevant Reference Asset appreciates over the term of the securities, you will realize a return equal to 100% (1.00x) of the relevant Reference Asset appreciation, subject to the relevant Maximum Cap. Should the relevant Reference Asset decline, you will lose 1% of your investment for every 1% decline in the relevant Reference Asset beyond the Buffer Percentage.

The graphs above illustrate the performance of the relevant Reference Asset from January 1, 2008 through June 13, 2018. The closing prices in the graph above were obtained from the Bloomberg Professional^® Service. Past performance is not necessarily an indication of future results. For further information, please see “Information Relating to the Securities Linked to the Technology Select Sector SPDR^®Fund” on page FWP-14, “Information Relating to the Securities Linked to the Financial Select Sector SPDR^®Fund” on page FWP-16 and page S-12 of the ETF Underlying Supplement and “Information Relating to the Securities Linked to The Market Vectors^®Gold Miners ETF” on page FWP-18 of this free writing prospectus and page S-32 of the ETF Underlying Supplement. We have derived all disclosure regarding the relevant Reference Asset from publicly available information. Neither HSBC USA Inc. nor any of its affiliates have undertaken any independent review of, or made any due diligence inquiry with respect to, the publicly available information about the relevant Reference Asset or any underlying index.

Financial Select Sector SPDR^® Fund│Technology Select Sector SPDR^® Fund │The Market Vectors^®Gold Miners ETF

This free writing prospectus relates to three offerings of Buffered Market Participation Securities. Each of the three securities will have the respective terms described in this free writing prospectus and the accompanying prospectus, prospectus supplement and ETF Underlying Supplement. If the terms of the securities offered hereby are inconsistent with those described in the accompanying prospectus, prospectus supplement or ETF Underlying Supplement, the terms described in this free writing prospectus shall control. You should be willing to forgo interest and dividend payments during the term of the securities and, if the relevant Reference Return is less than the Buffer Percentage, lose some or a significant portion (up to 90%) of your principal.

This free writing prospectus relates to three separate offerings of securities, each linked to the performance of a specific index fund (each a “Reference Asset”). Each of the three securities will have a Maximum Cap as indicated in the table below. The performance of each of the three securities does not depend on the performance of any of the other securities. The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to the relevant Reference Asset as described below. The following key terms relate to the offering of securities:

The Trade Date, the Pricing Date and the other dates set forth above are subject to change, and will be set forth in the final pricing supplement relating to the securities.

This free writing prospectus relates to separate offerings of securities, each linked to a different Reference Asset. The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to a single Reference Asset. We reserve the right to withdraw, cancel or modify any offering and to reject orders in whole or in part. Although each offering of securities relate to a Reference Asset, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to such Reference Asset or any component security included in such Reference Asset or as to the suitability of an investment in the securities.

You should read this document together with the prospectus dated February 26, 2018, the prospectus supplement dated February 26, 2018 and the ETF Underlying Supplement dated February 26, 2018. If the terms of the securities offered hereby are inconsistent with those described in the accompanying prospectus, prospectus supplement or ETF Underlying Supplement, the terms described in this free writing prospectus shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page FWP-8 of this free writing prospectus, page S-1 of the prospectus supplement and page S-1 of the ETF 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 ETF Underlying Supplement) with the SEC for the offering to which this free writing prospectus relates. Before you invest, you should read the prospectus, prospectus supplement and ETF Underlying Supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and these offerings. 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 these offerings will arrange to send you the prospectus, prospectus supplement and ETF Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

We are using this free writing prospectus to solicit from you an offer to purchase the securities. You may revoke your offer to purchase the securities at any time prior to the time at which we accept your offer by notifying HSBC Securities (USA) Inc. We reserve the right to change the terms of, or reject any offer to purchase, the securities prior to their issuance. In the event of any material changes to the terms of the securities, we will notify you.

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

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

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

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

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

The securities may be suitable for you if:

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

You are willing to invest in the securities based on the relevant Maximum Cap, which may limit your return at maturity.

You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the relevant Reference Return is below the Buffer Percentage of -10%.

You are willing to forgo dividends or other distributions paid to holders of the relevant Reference Asset or the stocks held by the relevant 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 relevant Reference Return will be negative or that the relevant Reference Return will not be sufficiently positive to provide you with your desired return.

You are unwilling to invest in the securities based on the relevant Maximum Cap, which may limit your return at maturity.

You are unwilling to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the relevant Reference Return is below the Buffer Percentage of -10%.

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 the holders of the relevant Reference Asset or the stocks held by the relevant 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.

You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the securities.

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and on page S-1 of the accompanying ETF Underlying Supplement. Investing in the securities is not equivalent to investing directly in the relevant Reference Asset or any of the stocks included in the related Underlying Index. 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 free writing prospectus and the accompanying, prospectus, prospectus supplement and ETF Underlying Supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and ETF 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 Index Funds” in the ETF Underlying Supplement.

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

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

You will not participate in any appreciation in the price of the relevant Reference Asset (as multiplied by the Upside Participation Rate) beyond the relevant Maximum Cap. You will not receive a return on the securities greater than the Maximum Cap.

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

The Final Price will be based on the Official Closing Price of the relevant Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the price of the relevant 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 price that is less than the Initial Price, 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 price of the relevant Reference Asset prior to such decrease. Although the actual price of the relevant Reference Asset on the Maturity Date or at other times during the term of the securities may be higher than the Final Price, the Payment at Maturity will be based solely on the Official Closing Price of the relevant Reference Asset on the Final Valuation Date.

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.

Owning the securities is not the same as owning the relevant Reference Asset or the stocks included in the related Underlying Index.

The return on your securities may not reflect the return you would realize if you actually owned the relevant Reference Asset or stocks included in the related Underlying Index. As a holder of the securities, you will not have voting rights or rights to receive dividends or other distributions or other rights as would holders of the relevant Reference Asset or the stocks included in the related Underlying Index.

Changes that affect the relevant Reference Asset or the related Underlying Index may affect the price of the relevant Reference Asset and the market value of the securities and the amount you will receive at maturity.

The policies of the reference issuer or S&P Dow Jones Indices LLC (the “Index Sponsor”), the index sponsor of the Underlying Index for each Reference Asset, concerning additions, deletions and substitutions of the constituents included in the relevant Reference Asset or the related Underlying Index, as applicable, and the manner in which the reference issuer or the Index Sponsor takes account of certain changes affecting those constituents included in the relevant Reference Asset or the related Underlying Index may affect the price of the relevant Reference Asset. The policies of the reference issuer or the Index Sponsor with respect to the calculation of the relevant Reference Asset or the related Underlying Index, as applicable, could also affect the price of the relevant Reference Asset. The reference issuer or the Index Sponsor may discontinue or suspend calculation or dissemination of the relevant Reference Asset or the related Underlying Index, as applicable. Any such actions could affect the price of the relevant Reference Asset and the value of 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 will be determined by us on the Pricing Date, will be less than the price to public and may differ from the market value of the securities in the secondary market, if any.

The Estimated Initial Value of the securities will be calculated by us on the Pricing Date and will be less than the price to public. The Estimated Initial Value will reflect our internal funding rate, which is the borrowing rate we pay to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the 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 will determine 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 price of the relevant 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 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 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 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.

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.

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 prospectus supplement.

Industry concentration risk and the risk associated with investments in a particular sector.

The securities held by the relevant Reference Asset operate in one industry. As a result, the return on the relevant Reference Asset may be lower, and more volatile, than that of an index fund which invests in a broader range of companies.

The holdings of the GDX are concentrated in the gold and silver mining industries.

All or substantially all of the equity securities held by the GDX are issued by gold or silver mining companies. An investment in the securities linked to the GDX will be concentrated in the gold and silver mining industries. Competitive pressures may have a significant effect on the financial condition of companies in these industries. In addition, these companies are highly dependent on the price of gold or silver, as applicable. These prices fluctuate widely and may be affected by numerous factors. Factors affecting gold prices include economic factors, including, among other things, the structure of and confidence in the global monetary system, expectations of the future rate of inflation, the relative strength of, and confidence in, the U.S. dollar (the currency in which the price of gold is generally quoted), interest rates and gold borrowing and lending rates, and global or regional economic, financial, political, regulatory, judicial or other events. Gold prices may also be affected by industry factors such as industrial and jewelry demand, lending, sales and purchases of gold by the official sector, including central banks and other governmental agencies and multilateral institutions which hold gold, levels of gold production and production costs, and short-term changes in supply and demand because of trading activities in the gold market. Factors affecting silver prices include general economic trends, technical developments, substitution issues and regulation, as well as specific factors including industrial and jewelry demand, expectations with respect to the rate of inflation, the relative strength of the U.S. dollar (the currency in which the price of silver is generally quoted) and other currencies, interest rates, central bank sales, forward sales by producers, global or regional political or economic events, and production costs and disruptions in major silver producing countries such as Mexico and Peru. The supply of silver consists of a combination of new mine production and existing stocks of bullion and fabricated silver held by governments, public and private financial institutions, industrial organizations and private individuals. In addition, the price of silver has on occasion been subject to very rapid short-term changes due to speculative activities. From time to time, above-ground inventories of silver may also influence the market.

The GDX invests in shares of gold and silver mining companies, but not in gold bullion or silver bullion. The GDX may under- or over-perform gold bullion and/or silver bullion over the term of the securities.

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 relevant Reference Asset relative to its Initial Price. We cannot predict the Final Price of the relevant Reference Asset. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events, and the hypothetical Initial Price used in the table and examples below is not expected to be the actual Initial Price. You should not take this illustration or these examples as an indication or assurance of the expected performance of the relevant 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 assume the following:

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 price of the Reference Asset increases from the Initial Price of $60.00 to a Final Price of $63.00.

Because the Reference Return is positive, and the Reference Return multiplied by the Upside Participation Rate is less than the Maximum Cap, the Final Settlement Value would be $1,050.00 per $1,000 Principal Amount, calculated as follows:

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

Example 2: The price of the Reference Asset increases from the Initial Price of $60.00 to a Final Price of $72.00.

Because the Reference Return is positive, and the Reference Return multiplied by the Upside Participation Rate is greater than the Maximum Cap, the Final Settlement Value would be $1,107.50 per $1,000 Principal Amount, calculated as follows:

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

Example 3: The price of the Reference Asset decreases from the Initial Price of $60.00 to a Final Price of $57.00.

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

Example 4: The price of the Reference Asset decreases from the Initial Price of $60.00 to a Final Price of $36.00

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

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

The graph below illustrates the daily performance of this Underlying from January 1, 2008 through June 13, 2018 based on closing price information from the Bloomberg Professional^® service. Past performance of this Underlying is not indicative of its future performance.

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 free writing prospectus. 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 relevant 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 relevant Reference Asset on that scheduled trading day, then the accelerated Final Valuation Date for the relevant 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.

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the securities. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the securities from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this free writing prospectus relates, for distribution to other registered broker-dealers, or will offer the securities directly to investors. HSBC Securities (USA) Inc. proposes to offer the securities at the price to public set forth on the cover page of this free writing prospectus. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 1.275% per $1,000 Principal Amount in connection with the distribution of the securities 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 securities.

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

We expect that delivery of the securities will be made against payment for the securities on or about the Original Issue Date set forth on the inside cover page of this document, which is more than two business days following the Trade Date. Under 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 securities more than two business days prior to the Original Issue Date will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

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

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 relevant 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, Mayer Brown LLP, it is reasonable to treat a security as a pre-paid executory contract with respect to the relevant Reference Asset. Pursuant to this approach and subject to the discussion below regarding “constructive ownership transactions,” we do not intend to report any income or gain with respect to the 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.

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

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

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

We will not attempt to ascertain whether the relevant Reference Asset or any of the entities whose stock is owned by the relevant 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 the relevant Reference Asset or one or more of the entities whose stock is owned by the relevant 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 relevant Reference Asset or the entities whose stock is owned by the relevant Reference Asset and consult your tax advisor regarding the possible consequences to you if the relevant Reference Asset or one or more of the entities whose stock is owned by the relevant 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.

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.

Payoff Example

The table at right shows the hypothetical payout profile of an investment in the securities reflecting the 100% (1.00x) Upside Participation Rate of 100%, reflecting the Buffer Percentage of -10%, and reflecting a Maximum Cap of 10.75%

Trade Date:	July 12, 2018
Pricing Date:	July 12, 2018
Original Issue Date:	July 17, 2018
Final Valuation Date:	October 13, 2019, which is subject to adjustment as described under “Additional Terms of the Notes—Valuation Dates” in the accompanying ETF Underlying Supplement.
Maturity Date:	3 business days after the Final Valuation Date, which is expected to be October 17, 2019. The Maturity Date is subject to adjustment as described under “Additional Terms of the Notes—Coupon Payment Dates, Call Payment Dates and Maturity Date” in the accompanying ETF Underlying Supplement.
Upside Participation Rate:	100% (1.00x)
Payment at Maturity:	On the Maturity Date, for each security, we will pay you the Final Settlement Value.
Reference Return:	With respect to each Reference Asset, the quotient, expressed as a percentage, calculated as follows:
	Final Price – Initial Price Initial Price
Final Settlement Value:	*If the relevant Reference Return is greater than zero,* you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, equal to the lesser of: (a) $1,000 + ($1,000 × Reference Return × Upside Participation Rate); and (b) $1,000 + ($1,000 × Maximum Cap). *If the relevant Reference Return is less than or equal to zero but greater than or equal to the Buffer Percentage, you will receive $1,000 per $1,000 Principal Amount (zero return). If the relevant Reference Return is less than the Buffer Percentage,* you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows: $1,000 + [$1,000 × (Reference Return + 10%)]. Under these circumstances, you will lose 1% of the Principal Amount of your securities for each percentage point that the relevant Reference Return is below the Buffer Percentage. For example, if the relevant Reference Return is -30%, you will suffer a 20% loss and receive 80% of the Principal Amount, subject to the credit risk of HSBC. If the relevant Reference Return is less than the Buffer Percentage, you will lose some or a significant portion (up to 90%) of your investment.
Buffer Percentage:	With respect to each offering, -10%
Initial Price:	The Official Closing Price of the relevant Reference Asset on the Pricing Date.
Final Price:	The Official Closing Price of the relevant Reference Asset on the Final Valuation Date.
Form of Securities:	Book-Entry
Listing:	The securities will not be listed on any U.S. securities exchange or quotation system.
Estimated Initial Value:	The Estimated Initial Value of the securities will be less than the price you pay to purchase the securities. 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, at any time. The Estimated Initial Value will be calculated on the Pricing Date. See “Risk Factors — The Estimated Initial Value of the securities, which will be determined by us on the Pricing Date, will be less than the price to public and may differ from the market value of the securities in the secondary market, if any.”
