$3,581,000 PLUS Based on the Level of the TOPIX^® Index due December 4, 2019

The PLUS offered are senior unsecured debt securities of HSBC USA Inc. (“HSBC”), will not pay interest, do not guarantee any return of principal at maturity and have the terms described in the accompanying Equity Index Underlying Supplement, prospectus supplement and prospectus, as supplemented or modified by this pricing supplement. All references to “Reference Asset” in the prospectus supplement and the Equity Index Underlying Supplement shall refer to the “underlying index” herein. At maturity, if the level of the underlying index has appreciated from the initial level, investors will receive the stated principal amount of their investment plus a payment reflecting the leveraged upside performance of the underlying index, subject to the maximum payment at maturity. However, at maturity, if the level of the underlying index has depreciated, the investor will lose 1% for every 1% decline in the level of the underlying index. The PLUS are for investors who seek an equity index-based return and who are willing to risk their principal and forgo current income and upside above the maximum payment at maturity in exchange for the leverage feature, which applies to a limited range of positive performance of the underlying index. Investors may lose up to 100% of the stated principal amount of the PLUS. All payments on the PLUS are subject to the credit risk of HSBC.

The estimated initial value of the PLUS on the pricing date is $9.718 per PLUS, which is less than the price to public. The market value of the PLUS at any time will reflect many factors and cannot be predicted with accuracy. See “Estimated initial value” above and “Risk Factors” beginning on page 5 of this document for additional information.

An investment in the PLUS involves certain risks. See “Risk Factors” beginning on page 5 of this pricing supplement, page S-1 of the Equity Index Underlying Supplement and page S-1 of the prospectus supplement.

Tax considerations:	There is no direct legal authority as to the proper tax treatment of each PLUS, and therefore significant aspects of the tax treatment of each PLUS are uncertain as to both the timing and character of any inclusion in income in respect of each PLUS. Under one approach, each PLUS could be treated as a pre-paid executory contract with respect to the underlying index. We intend to treat each PLUS consistent with this approach. Pursuant to the terms of each PLUS, you agree to treat each PLUS 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 each PLUS as a pre-paid executory contract with respect to the underlying index. Pursuant to this approach, we do not intend to report any income or gain with respect to each PLUS prior to 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 PLUS for more than one year at such time for U.S. federal income tax purposes. In Notice 2008-2, the Internal Revenue Service and the Treasury Department requested comments as to whether the purchaser of certain securities (which may include the PLUS) should be required to accrue income during its term under a mark-to-market, accrual or other methodology, whether income and gain on such a security or contract should be ordinary or capital and whether foreign holders should be subject to withholding tax on any deemed income accrual. Accordingly, it is possible that regulations or other guidance could provide that a U.S. holder of a PLUS is required to accrue income in respect of the PLUS prior to the receipt of payments under the PLUS or its earlier sale or exchange. Moreover, it is possible that any such regulations or other guidance could treat all income and gain of a U.S. holder in respect of a PLUS as ordinary income (including gain on a sale or exchange). Finally, it is possible that a non-U.S. holder (as defined under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement) of the PLUS could be subject to U.S. withholding tax in respect of a PLUS. It is unclear whether any regulations or other guidance would apply to the PLUS (possibly on a retroactive basis). Prospective investors are urged to consult with their tax advisors regarding Notice 2008-2 and the possible effect to them of the issuance of regulations or other guidance that affects the U.S. federal income tax treatment of the PLUS. We will not attempt to ascertain whether any of the entities whose stock is included in the underlying index would be treated as a passive foreign investment company (a “PFIC”) or United States real property holding corporation (a “USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the underlying index 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 entities whose stock is included in the underlying index and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the underlying index 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 PLUS is likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their tax advisors regarding the U.S. federal estate tax consequences of investing in the PLUS. For a further discussion of U.S. federal income tax consequences related to each PLUS, see the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.
