Risk Factors

Please see the Preliminary Offering Documents for a description of certain risks related to this investment, including, but not limited to, the following:

· Depending on the performance of the Basket as measured shortly before the maturity date, you may lose up to 90% of the principal amount.

· Payments on the notes, including repayment of principal, are subject to the credit risk of HSBC. If HSBC becomes insolvent or is unable to pay its obligations, you may lose your entire investment.

· Changes in the level of one of the Basket Components may be offset by changes in the levels of the other Basket Components.

· The estimated initial value of the notes on the pricing date will be less than their public offering price.

· If you attempt to sell the notes prior to maturity, their market value may be lower than both the public offering price and the estimated initial value of the notes on the pricing date.

· You will have no rights of a holder of the securities included in the Basket Components, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

· Your return on the notes may be affected by factors affecting the international securities markets, specifically changes in the countries represented by the Basket Components. In addition, you will not obtain the benefit of any increase in the value of the currencies in which the securities included in the Basket Components trade against the U.S. dollar which you would have received if you had owned the securities in the Basket Components during the term of your notes, although the value of the Basket may be adversely affected by general exchange rate movements in the market.
