⁽¹⁾ Calculated in accordance with Rule 457(r) of the Securities Act of 1933, as amended.

The notes are being issued by HSBC USA Inc. (“HSBC”). Investing in the notes involves a number of risks. There are important differences between the notes and a conventional debt security, including different investment risks and costs. See “Risk Factors” beginning on page TS-6 of this term sheet and beginning on page PS-7 of product supplement EQUITY INDICES STR-1.

The estimated initial value of the notes on the pricing date is $9.51 per unit, which is less than the public offering price listed below. The market value of the notes at any time will reflect many factors and cannot be predicted with accuracy. See “Summary” on page TS-2 and “Risk Factors” beginning on page TS-6 of this term sheet for additional information.

Neither the Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the notes or passed upon the accuracy or the adequacy of this document, the accompanying product supplement, prospectus or prospectus supplement. Any representation to the contrary is a criminal offense.

⁽¹⁾ The public offering price and underwriting discount for an aggregate of 500,000 units purchased by an individual investor or in combined transactions with the investor's household will be $9.95 per unit and $0.15 per unit, respectively. See “Supplement to the Plan of Distribution” below.

The Strategic Accelerated Redemption Securities^®Linked to the S&P 500^®Index, due April 19, 2024 (the “notes”) are our senior unsecured debt securities and are not a direct or indirect obligation of any third party. The notes are not deposit liabilities or other obligations of a bank and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other governmental agency of the United States or any other jurisdiction. The notes will rank equally with all of our other senior unsecured debt. Any payments due on the notes, including any repayment of principal, depend on the credit risk of HSBC and its ability to satisfy its obligations as they come due. The notes will be automatically called at the applicable Call Amount if the closing level of the Index, which is the S&P 500^®Index (the “Index”), on any Observation Date is equal to or greater than the Starting Value. If your notes are not called, you will lose all or a portion of the principal amount of your notes. Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

The estimated initial value of the notes is less than the price you pay to purchase the notes. The estimated initial value was determined by reference to our or our affiliates’ internal pricing models and reflects our internal funding rate, which is the borrowing rate we pay to issue market-linked notes, and the market prices for hedging arrangements related to the notes (which may include call options, put options or other derivatives). This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. The difference in the borrowing rate, as well as the underwriting discount and the costs associated with hedging the notes, including the hedging related charge described below, reduced the economic terms of the notes (including the Call Amounts and Call Premiums). The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes.

The terms and risks of the notes are contained in this term sheet and the documents listed below (together, the “Note Prospectus”). The documents have been filed as part of a registration statement with the SEC, which may, without cost, be accessed on the SEC website as indicated below or obtained from MLPF&S by calling 1-800-294-1322:

Our Central Index Key, or CIK, on the SEC website is 83246. Before you invest, you should read the Note Prospectus, including this term sheet, for information about us and this offering. Any prior or contemporaneous oral statements and any other written materials you may have received are superseded by the Note Prospectus. You should carefully consider, among other things, the matters set forth under “Risk Factors” in the section indicated on the cover of this term sheet. The notes involve risks not associated with conventional debt securities. Capitalized terms used but not defined in this term sheet have the meanings set forth in product supplement EQUITY INDICES STR-1. Unless otherwise indicated or unless the context requires otherwise, all references in this document to “we,” “us,” “our,” or similar references are to HSBC.

We urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

The following examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. They illustrate the calculation of the Call Amount or Redemption Amount, as applicable, based on the hypothetical terms set forth below. The actual amount you receive and the resulting return will depend on the actual Starting Value, Threshold Value, Call Level, Observation Levels, and term of your investment. The following examples do not take into account any tax consequences from investing in the notes. These examples are based on:

The hypothetical Starting Value of 100.00 used in these examples has been chosen for illustrative purposes only. The actual Starting Value is 2,613.16, which was the closing level of the Index on the pricing date. For recent actual levels of the Index, see “The Index” section below. The Index is a price return index and as such the level of the Index will not include any income generated by dividends paid on the stocks included in the Index, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.Notes Are Called on an Observation Date

The notes will be called at $10.00 plus the applicable Call Premium if the Observation Level on one of the Observation Dates is equal to or greater than the Call Level. After the notes are called, they will no longer remain outstanding and there will not be any further payments on the notes.

Example 1 – The Observation Level on the first Observation Date is 110.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $0.82 = $10.82 per unit.

Example 2 – The Observation Level on the first Observation Date is below the Call Level, but the Observation Level on the second Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $1.64 = $11.64 per unit.

Example 3 - The Observation Levels on the first and second Observation Dates are below the Call Level, but the Observation Level on the third Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $2.46 = $12.46 per unit.

Example 4 - The Observation Levels on the first, second and third Observation Dates are below the Call Level, but the Observation Level on the fourth Observation Date is 110.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $3.28 = $13.28 per unit.

Example 5 - The Observation Levels on the first, second, third and fourth Observation Dates are below the Call Level, but the Observation Level on the fifth Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $4.10 = $14.10 per unit.

Example 6 - The Observation Levels on the first, second, third, fourth and fifth Observation Dates are below the Call Level, but the Observation Level on the sixth and final Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $4.92 = $14.92 per unit.

Example 7 - The notes are not called on any Observation Date and the Ending Value is less than the Threshold Value. The Redemption Amount will be less, and possibly significantly less, than the principal amount. For example, if the Ending Value is 85.00, the Redemption Amount per unit will be:

We urge you to read the section “Risk Factors” in the product supplement and in the accompanying prospectus supplement. Investing in the notes is not equivalent to investing directly in the stocks included in the Index. You should understand the risks of investing in the notes and should reach an investment decision only after careful consideration, with your advisers, with respect to the notes in light of your particular financial and other circumstances and the information set forth in this term sheet and the accompanying product supplement, prospectus supplement and prospectus.

In addition to the risks in the product supplement identified below, you should review “Risk Factors” in the accompanying prospectus supplement, including the explanation of risks relating to the notes described in the section “— Risks Relating to All Note Issuances.”

We have derived all information relating to the Index including, without limitation, its make-up, performance, method of calculation and changes in its components, from publicly available sources. That information reflects the policies of and is subject to change by S&P Dow Jones Indices LLP (“S&P” or the “Index sponsor”). The Index sponsor is under no obligation to continue to publish, and may discontinue or suspend the publication of the Index at any time.

The Index is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the Index, discussed below in further detail, is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 500 companies as of a particular time compared to the aggregate average Market Value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

The Index does not reflect the payment of dividends on the stocks included in the Index and therefore the payment on the notes will not produce the same return you would receive if you were able to purchase such underlying stocks.

Relevant criteria employed by the Index sponsor include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the market price of that company’s common stock is generally responsive to changes in the affairs of the respective industry and the market value and trading activity of the common stock of that company. Eleven main industry groups comprise the Index: Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care, Industrials, Information Technology, Materials, Real Estate, Telecommunication Services and Utilities. Changes in the Index are reported daily in the financial pages of many major newspapers, on Bloomberg Professional^® service under the symbol “SPX” and on the Index sponsor website. Information contained in the Index sponsor’s website is not incorporated by reference in, and should not be considered a part of, this document.

Prior to March 2005, the Market Value of a component stock was calculated as the product of the market price per share and the total number of outstanding shares of the component stock. In March 2004, the Index sponsor announced that it would transition the Index to float adjusted market capitalization weights. The transition began in March 2005 and was completed in September 2005. The Index sponsor’s criteria for selecting stock for the Index were not changed by the shift to float adjustment. However, the adjustment affects each company’s weight in the Index (i.e., its Market Value). Currently, the Index sponsor calculates the Index based on the total float-adjusted market capitalization of each component stock, where each stock’s weight in the Index is proportional to its float-adjusted Market Value.

Under the float adjustment, the share counts used in calculating the Index reflect only those shares that are available to investors, not all of a company’s outstanding shares. The float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

All shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” are removed from the float for purposes of calculating the Index. Generally, these “control shareholders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float. Treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares of a U.S. company traded in Canada as “exchangeable shares” are normally part of the float unless those shares form a control block. All multiple share class companies that have listed share class lines will be adjusted for shares and float such that each share class line will only represent that line’s shares and float. The decision to include each publicly listed line is evaluated individually. All multiple share class companies that have an unlisted class line will also be adjusted.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares by the total shares outstanding. As of September 21, 2012, available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, the Index sponsor would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, the Index sponsor would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the Index. Constituents of the Index prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the Index. If a constituent company of the Index reorganizes into a multiple share class line structure, that company will remain in the Index at the discretion of the S&P Index Committee in order to minimize turnover. For companies with multiple classes of stock, the Index sponsor calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

The Index is also calculated using a base-weighted aggregate methodology: the level of the Index reflects the total Market Value of all the component stocks relative to the Index base period of 1941-43. The daily index value of the Index is the quotient of the total float-adjusted market capitalization of the index’s constituents and its index divisor (the “Divisor”.)

Ongoing maintenance of the Index includes monitoring and completing the adjustments for additions and deletions of the constituent companies, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spin-offs. Continuity in the level of the Index is maintained by adjusting the Divisor for all changes in the Index constituents’ share capital after the base date. Some corporate actions, such as stock splits and stock dividends do not require Divisor adjustments because following a stock split or stock dividend, both the stock price and number of shares outstanding are adjusted by the Index sponsor so that there is no change in the Market Value of the component stock. Corporate actions (such as stock splits, stock dividends, non-zero price spin-offs and rights offerings) are applied after the close of trading on the day before the ex-date.

To prevent the level of the Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the Index also require a Divisor adjustment. By adjusting the Divisor for the change in total Market Value, the level of the Index remains constant. This helps maintain the level of the Index as an accurate barometer of stock market performance and ensures that the movement of the Index does not reflect the corporate actions of individual companies in the Index. The divisor is adjusted such that the index value at an instant just prior to a change in base capital equals the index value at an instant immediately following that change. As noted in the preceding paragraph, some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the Index and do not require Divisor adjustments.

Index maintenance adjustments will be made to account for certain corporate actions, such as addition/deletion of companies, change in shares outstanding, stock split, spin-off, change in IWF, special dividend, and rights offering. For certain index maintenance adjustments, the divisor will be adjusted and a new divisor will be calculated to account for the altered Market Value of the Index.

Another large part of the Index maintenance process involves tracking the changes in the number of shares outstanding of each of the companies whose stocks are included in the Index. To prevent the level of the Index from changing due to corporate actions, corporate actions which affect the total Market Value of the Index require a Divisor adjustment. By adjusting the Divisor for the change in Market Value, the level of the Index remains constant and does not reflect the corporate actions of individual companies in the Index. Divisor adjustments are made after the close of trading and after the calculation of the Index closing level.

Changes in a company’s shares outstanding and IWF due to its acquisition of another public company are made as soon as reasonably possible. At the Index sponsor’s discretion, de minimis merger and acquisition share changes are accumulated and implemented with the quarterly share rebalancing.

All other changes of less than 5% are accumulated and made quarterly on the third Friday of March, June, September, and December.

Changes in a company’s total shares outstanding of 5% or more due to public offerings are made as soon as reasonably possible. Other changes of 5% or more (for example, due to tender offers, Dutch auctions, voluntary exchange offers, company stock repurchases, private placements, acquisitions of private companies or non-index companies that do not trade on a major exchange, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participations, at-the-market stock offerings or other recapitalizations) are made weekly, and are generally announced on Fridays for implementation after the close of trading the following Friday (one week later). If a 5% or more share change causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case-by-case basis.

The following graph shows the daily historical performance of the Index in the period from January 1, 2008 through April 9, 2018. We obtained this historical data from Bloomberg L.P. We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On the pricing date, the closing level of the Index was 2,613.16.

This historical data on the Index is not necessarily indicative of the future performance of the Index or what the value of the notes may be. Any historical upward or downward trend in the level of the Index during any period set forth above is not an indication that the level of the Index is more or less likely to increase or decrease at any time over the term of the notes.

Before investing in the notes, you should consult publicly available sources for the levels of the Index.

We will deliver the notes against payment therefor in New York, New York on a date that is greater than two business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such 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 alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S acting as a principal in effecting the transaction for your account.

MLPF&S may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these will include MLPF&S’s trading commissions and mark-ups. MLPF&S may act as principal or agent in these market-making transactions; however, it is not obligated to engage in any such transactions. At MLPF&S’s discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the estimated initial value of the notes. Any price offered by MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Index, the remaining term of the notes, and the issuer’s creditworthiness. However, neither we nor any of our affiliates is obligated to purchase your notes at any price, or at any time, and we cannot assure you that we, MLPF&S or any of our respective affiliates will purchase your notes at a price that equals or exceeds the estimated initial value of the notes.

The value of the notes shown on your account statement provided by MLPF&S will be based on their estimate of the value of the notes if MLPF&S or one of its affiliates were to make a market in the notes, which it is not obligated to do. This estimate will be based upon the price that MLPF&S may pay for the notes in light of then-prevailing market conditions, and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the estimated initial value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding HSBC or for any purpose other than that described in the immediately preceding sentence.

An investor’s household, as referenced on the cover of this term sheet, will generally include accounts held by any of the following, as determined by MLPF&S in its discretion and acting in good faith based upon information then available to MLPF&S:

Purchases in retirement accounts will not be considered part of the same household as an individual investor’s personal or other non-retirement account, except for individual retirement accounts (“IRAs”), simplified employee pension plans (“SEPs”), savings incentive match plan for employees (“SIMPLEs”), and single-participant or owners only accounts (i.e., retirement accounts held by self-employed individuals, business owners or partners with no employees other than their spouses).

Please contact your Merrill Lynch financial advisor if you have any questions about the application of these provisions to your specific circumstances or think you are eligible.

MLPF&S will participate as selling agent in the distribution of the notes. Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 per unit principal amount and will depend on the performance of the Index. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with MLPF&S or one of its affiliates. The terms of these hedging arrangements are determined by MLPF&S seeking bids from market participants, which could include one of our affiliates and MLPF&S and its affiliates. These hedging arrangements take into account a number of factors, including the issuer’s creditworthiness, interest rate movements, the volatility of the Index, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes depend in part on the terms of the hedging arrangements.

MLPF&S has advised us that the hedging arrangements will include a hedging related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to MLPF&S from these transactions. Since hedging entails risk and may be influenced

by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by MLPF&S or any third party hedge providers.

MLPF&S classifies certain market-linked investments (the “Market-Linked Investments”) into categories, each with different investment characteristics. The following description is meant solely for informational purposes and is not intended to represent any particular Enhanced Return Market-Linked Investment or guarantee any performance.

Enhanced Return Market-Linked Investments are short- to medium-term investments that offer you a way to enhance exposure to a particular market view without taking on a similarly enhanced level of market downside risk. They can be especially effective in a flat to moderately positive market (or, in the case of bearish investments, a flat to moderately negative market). In exchange for the potential to receive better-than market returns on the linked asset, you must generally accept market downside risk and capped upside potential. As these investments are not market downside protected, and do not assure full repayment of principal at maturity, you need to be prepared for the possibility that you may lose all or part of your investment.
