Investment Description

· Linked to the EURO STOXX 50^® Index

· Unlike ordinary debt securities, the securities do not pay interest or repay a fixed amount of principal at maturity. Instead, the securities provide for a Payment at Maturity that may be greater than, equal to or less than the Principal Amount, depending on the performance of the Reference Asset from its Initial Level to its Final Level.

The Payment at Maturity will be calculated as follows:

o If the level of the Reference Asset increases from the Initial Level to the Final Level:

You will receive the Principal Amount plus 200% participation in the upside performance of the Reference Asset, subject to a Maximum Cap of [60% to 65%] (to be determined on the Pricing Date)

o If the level of the Reference Asset does not change, or decreases but the decrease is not more than 20.00%, from the Initial Level to the Final Level:

You will be repaid the Principal Amount (zero return)

o If the level of the Reference Asset decreases by more than 20.00% from the Initial Level to the Final Level:

You will receive less than the Principal Amount and will have 1-to-1 downside exposure to the decrease in the level of the Reference Asset in excess of 20.00%

· Investors may lose up to 80.00% of the Principal Amount

· All payments on the securities are subject to the credit risk of HSBC, and you will have no ability to pursue the issuers of any securities included in the Reference Asset for payment; if HSBC defaults on its obligations, you could lose some or all of your investment

· No periodic interest payments or dividends

· No exchange listing; designed to be held to maturity

*To the extent that the Issuer makes any change to the expected Pricing Date or expected Original Issue Date, the Final Valuation Date and Maturity Date may also be changed in the Issuer’s discretion to ensure that the term of the securities remains the same.

The Estimated Initial Value of the securities on the Pricing Date is expected to be between $920 and $960 per security, 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. 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 and will be set forth in the final pricing supplement. 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” in the accompanying free writing prospectus.

You should carefully consider, among other things, the matters set forth in “Risk Factors” in this term sheet, beginning on page FWP-8 of the free writing prospectus, page S-1 of the prospectus supplement and page S-2 of the Equity Index Underlying Supplement, as the securities involve risks not associated with conventional debt securities.

This introductory term sheet does not provide all of the information that an investor should consider prior to making an investment decision.

Investors should carefully review the accompanying free writing prospectus, Equity Index Underlying Supplement, prospectus supplement and prospectus before making a decision to invest in the securities. Terms used herein without definition will have the meanings ascribed to them in the accompanying free writing prospectus.

How the Payment at Maturity Is Calculated

On the Maturity Date, for each security you hold, we will pay you the Payment at Maturity, which is an amount in cash, calculated as follows:

· If the 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:

(i) $1,000 + ($1,000 x Reference Return x Upside Participation Rate); and

(ii) $1,000 + ($1,000 x Maximum Cap)

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

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

$1,000 + [$1,000 × (Reference Return + 20.00%)]

If the Reference Return is less than the Buffer Value, you will lose some or a significant portion (up to 80.00%) of the Principal Amount.
