Autocallable Market-Linked Step Up Notes

Linked to the EURO STOXX 50^® Index, due November , 2022

Summary

The Autocallable Market-Linked Step Up Notes Linked to the EURO STOXX 50^® Index, due November , 2022 (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 Observation Level of the Market Measure, which is the EURO STOXX 50^® Index (the “Index”), is equal to or greater than the Call Level on the relevant Observation Date. If the notes are not called, at maturity, the notes provide you with a Step Up Payment if the Ending Value of the Index is equal to or greater than the Starting Value, but is not greater than the Step Up Value. If the Ending Value is greater than the Step Up Value, you will participate on a 1-for-1 basis in the increase in the level of the Index above the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Any payments on the notes 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 will be less than the price you pay to purchase the notes. The estimated initial value is 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, will reduce the economic terms of the notes (including the Call Premiums and Call Amounts). The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes. The estimated initial value will be calculated on the pricing date and will be set forth in the pricing supplement to which this term sheet relates.

Hypothetical Payout Profile at Maturity

The graph below is based on hypothetical numbers and values. The graph below shows a payout profile at maturity, which would only apply if the notes are not called on any Observation Date.

Autocallable Market-Linked Step Up Notes     This graph reflects the returns on the notes, based on the Threshold Value of 100% of the Starting Value, the Step Up Payment of $3.50 per unit and the Step Up Value of 135% of the Starting Value. The green line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the stocks included in the Index, excluding dividends.   This graph has been prepared for purposes of illustration only. 

Hypothetical Payments at Maturity

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes, assuming the notes are not called on any Observation Date. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value, Threshold Value, Ending Value and Step Up Value, whether the notes are called on an Observation Date, and term of your investment.

The following table is based on a Starting Value of 100, a Threshold Value of 100, a Step Up Value of 135 and the Step Up Payment of $3.50 per unit. It illustrates the effect of a range of Ending Values on the Redemption Amount per unit of the notes and the total rate of return to holders of the notes. The following examples do not take into account any tax consequences from investing in the notes.

Ending Value	Percentage Change from the Starting Value to the Ending Value	Redemption Amount per Unit	Total Rate of Return on the Notes
0.00	-100.00%	$0.00	-100.00%
50.00	-50.00%	$5.00	-50.00%

100.00(1)(2)	0.00%	$13.50(3)	35.00%
102.00	2.00%	$13.50	35.00%
105.00	5.00%	$13.50	35.00%
110.00	10.00%	$13.50	35.00%
120.00	20.00%	$13.50	35.00%
130.00	30.00%	$13.50	35.00%
135.00(4)	35.00%	$13.50	35.00%
140.00	40.00%	$14.00	40.00%
150.00	50.00%	$15.00	50.00%
154.00	54.00%	$15.40	54.00%

(1) This is the hypothetical Threshold Value.

(2) The hypothetical Starting Value of 100.00 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value for the Index.

(3) This amount represents the sum of the principal amount and the Step Up Payment of $3.50.

(4) This is the hypothetical Step Up Value.

For recent actual levels of the Index, see “The Index” section below. The Index is a price return index and as such the Ending Value 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.

Risk Factors

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.”

§ If the notes are not automatically called, depending on the performance of the Index as measured shortly before the maturity date, you may lose up to 100% of the principal amount.

§ Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

§ If the notes are called, your investment return is limited to the return represented by the applicable Call Premium.

§ Your investment return may be less than a comparable investment directly in the stocks included in the Index.

§ Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

§ The estimated initial value of the notes will be less than the public offering price and may differ from the market value of the notes in the secondary market, if any. We will determine the estimated initial value 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. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. Different pricing models and assumptions could provide valuations for the notes that are different from our estimated initial value. The estimated initial value will reflect our internal funding rate we use to issue market-linked notes, as well as the mid-market value of the hedging arrangements related to the notes (which may include call options, put options or other derivatives).

§ Our internal funding rate for the issuance of these notes is lower than the rate we would use when we issue conventional fixed or floating rate debt securities. This is one of the factors that may result in the market value of the notes being less than their estimated initial value. 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 levels 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.

§ The price of your notes in the secondary market, if any, immediately after the pricing date will be less than the public offering price. The public offering price takes into account certain costs, principally the underwriting discount, the hedging costs described on page TS-11 and the costs associated with issuing the notes. The costs associated with issuing the notes will be used or retained by us or one of our affiliates. 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.

§ The estimated initial value does not represent a minimum price at which we, MLPF&S, BofAS or any of our respective 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, at any time after issuance will vary based on many factors, including the level of the Index 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.

§ A trading market is not expected to develop for the notes. None of us, MLPF&S or BofAS is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

§ Our business, hedging and trading activities, and those of MLPF&S, BofAS and our respective affiliates (including trades in shares of companies included in the Index), and any hedging and trading activities we, MLPF&S, BofAS or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

§ The Index sponsor may adjust the Index in a way that affects its level, and has no obligation to consider your interests.

§ You will have no rights of a holder of the securities represented by the Index, and you will not be entitled to receive securities or dividends or other distributions by issuers of those securities.

§ While we, MLPF&S, BofAS or our respective affiliates may from time to time own securities of companies included in the Index, we, MLPF&S, BofAS and our respective affiliates do not control any company included in the Index, and have not verified any disclosure made by any other company.

§ Your return on the notes may be affected by factors affecting the international securities markets, specifically changes within the Eurozone. The Eurozone is and has been undergoing severe financial stress and the political, legal, and regulatory ramifications are impossible to predict. Changes within the Eurozone could adversely affect the performance of the Index and, consequently, the value of the notes. In addition, you will not obtain the benefit of any increase in the value of the euro against the U.S. dollar, which you would have received if you had owned the securities in the Index during the term of your notes, although the level of the Index may be adversely affected by general exchange rate movements in the market.

§ There may be potential conflicts of interest involving the calculation agents, one of which is us and one of which is BofAS. We have the right to appoint and remove the calculation agents.

§ The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes. See “Summary Tax Consequences” below and “U.S. Federal Income Tax Summary” beginning on page PS-32 of product supplement EQUITY INDICES SUN-1.

Other Terms of the Notes

The provisions of this section supersede and replace the definition of “Market Measure Business Day” set forth in product supplement EQUITY INDICES SUN-1.

Market Measure Business Day

A “Market Measure Business Day” means a day on which:

(A) the Eurex (or any successor) is open for trading; and

(B) the Index or any successor thereto is calculated and published.

The Index

We have derived all information contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available sources. That information reflects the policies of and is subject to change by, STOXX Limited. STOXX Limited is under no obligation to continue to publish, and may discontinue or suspend the publication of the Index at any time. The consequences of STOXX Limited discontinuing publication of the Index are discussed in the section entitled “Description of the Notes—Discontinuance of an Index” beginning on page PS-22 of product supplement EQUITY INDICES SUN-1. None of us, the calculation agents, MLPF&S or BofAS accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

STOXX Limited Publishes the Index

The Index was created by STOXX Limited, which is owned by Deutsche Börse AG. Publication of the Index began on February 28, 1998, based on an initial index value of 1,000 at December 31, 1991. The Index is reported daily on the Bloomberg Professional^® service under the symbol “SX5E” and on the STOXX Limited website. Information contained in the STOXX Limited website is not incorporated by reference in, and should not be considered a part of, this term sheet.

Index Composition and Maintenance

The Index is composed of 50 stocks from 11 Eurozone countries (Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain) of the STOXX Europe 600 Supersector indices. The STOXX 600 Supersector indices contain the 600 largest stocks traded on the major exchanges of 18 European countries and are organized into the following 19 Supersectors: automobiles & parts; banks; basic resources; chemicals; construction & materials; financial services; food & beverage; health care; industrial goods & services; insurance; media; oil & gas; personal & household goods; real estate; retail; technology; telecommunications; travel & leisure and utilities.

The Index is weighted by free float market capitalization. Each component’s weight is capped at 10% of the Index’s total free float market capitalization. Free float weights are reviewed quarterly and the Index’s composition is reviewed annually in September. The review cut-off date is the last trading day of August.

Within each of the 19 EURO STOXX Supersector indices, the component stocks are ranked by free float market capitalization. The largest stocks are added to the selection list until the coverage is close to, but still less than, 60% of the free float market capitalization of the corresponding EURO STOXX Total Market Index Supersector index. If the next-ranked stock brings the coverage closer to 60% in absolute terms, then it is also added to the selection list. All current component stocks are then added to the selection list. The stocks on the selection list are ranked by free float market capitalization. In exceptional cases, the STOXX Limited Supervisory Board may make additions and deletions to the selection list.

The 40 largest stocks on the selection list are chosen as components. The remaining 10 stocks are selected from the largest remaining current components of the Index that are ranked between 41 and 60. If the component number is still below 50, then the largest remaining stocks on the selection list are added until the Index contains 50 stocks.

Index Calculation

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

 

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

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

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, if the initial settlement of the notes occurs more than two business days from the pricing date, 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 and/or one of its affiliates acting as a principal in effecting the transaction for your account.

MLPF&S will purchase the notes from BofAS for resale, and will receive a selling concession in connection with the sale of the notes in an amount up to the full amount of underwriting discount set forth on the cover of this term sheet.

MLPF&S and BofAS 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 and BofAS’s trading commissions and mark-ups or mark-downs. MLPF&S and BofAS may act as principal or agent in these market-making transactions; however, neither is obligated to engage in any such transactions. At their discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S and BofAS 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 or BofAS 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 are obligated to purchase your notes at any price, or at any time, and we cannot assure you that we, MLPF&S, BofAS 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 BofAS’s estimate of the value of the notes if BofAS 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 BofAS 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:

· the investor’s spouse (including a domestic partner), siblings, parents, grandparents, spouse’s parents, children and grandchildren, but excluding accounts held by aunts, uncles, cousins, nieces, nephews or any other family relationship not directly above or below the individual investor;

· a family investment vehicle, including foundations, limited partnerships and personal holding companies, but only if the beneficial owners of the vehicle consist solely of the investor or members of the investor’s household as described above; and

· a trust where the grantors and/or beneficiaries of the trust consist solely of the investor or members of the investor’s household as described above; provided that, purchases of the notes by a trust generally cannot be aggregated together with any purchases made by a trustee’s personal account.

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

Role of MLPF&S and BofAS

BofAS will participate as selling agent in the distribution of the notes. Under our distribution agreement with BofAS, BofAS 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 BofAS or one of its affiliates. The terms of these hedging arrangements are determined by BofAS seeking bids from market participants, which could include one of our affiliates and MLPF&S, BofAS and their 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.

BofAS 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 BofAS 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 BofAS or any third party hedge providers.

Summary Tax Consequences

You should consider the U.S. federal income tax consequences of an investment in the notes, including the following:

§ There is no statutory, judicial, or administrative authority directly addressing the characterization of the notes.

§ You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the notes for all tax purposes as pre-paid executory contracts with respect to the Index.

§ Under this characterization and tax treatment of the notes, a U.S. holder (as defined in the prospectus supplement) generally will recognize capital gain or loss upon maturity or upon a sale or exchange of the notes prior to maturity. This capital gain or loss generally will be long-term capital gain or loss if you held the notes for more than one year.

§ No assurance can be given that the IRS or any court will agree with this characterization and tax treatment.

§ A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, Internal Revenue Service guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2021. Based on our determination that the notes are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the notes. However, it is possible that the notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Index or the notes, and following such occurrence the notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the Index 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.

§ The discussion in the accompanying prospectus supplement under “U.S. Federal Income Tax Considerations – Foreign Account Tax Compliance Act” is hereby modified to reflect regulations proposed by the U.S. Department of Treasury indicating its intent to eliminate the requirements under FATCA of withholding on gross proceeds from the sale, exchange, settlement at maturity or other disposition of relevant financial instruments. The U.S. Department of Treasury has indicated that taxpayers may rely on these proposed regulations pending their finalization.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws. You should review carefully the discussion under the section entitled “U.S. Federal Income Tax Summary” beginning on page PS-32 of product supplement EQUITY INDICES SUN-1.
