All references to “Enhanced Market Participation Notes” in the accompanying product supplement shall refer to these Buffered Accelerated Market Participation Securities. This offering of securities has the terms described in this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus. If the terms of the securities offered hereby are inconsistent with those described in the accompanying product supplement, prospectus supplement, or prospectus, the terms described in this pricing supplement shall control. You should be willing to forgo interest and dividend payments during the term of the securities and, if the Reference Return is negative, lose up to 90% of your principal.

This pricing supplement relates to an offering of securities linked to the performance of Gold (the “Reference Asset”). The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to the Reference Asset as described below. The following key terms relate to the offering of securities:

Issuer:	HSBC USA Inc.
Principal Amount:	$1,000 per security
Reference Asset:	Gold, represented by the price of one troy ounce of gold as further described under “Official Closing Price” below.
Pricing Date:	November 22, 2011
Trade Date:	November 22, 2011
Original Issue Date:	November 28, 2011
Final Valuation Date:	May 22, 2013. The Final Valuation Date is subject to adjustment as described in the accompanying product supplement.
Maturity Date:	3 business days after the Final Valuation Date, which is expected to be May 28, 2013. The Maturity Date is subject to adjustment as described under “Specific Terms of the Notes — Market Disruption Events” in the accompanying product supplement and acceleration as described below under “Supplemental Information Relating to the Terms of the Securities — Commodity Hedging Disruption Events.”
Upside Participation Rate:	150%
Maximum Cap:	22.00%
Payment at Maturity:	On the Maturity Date, for each security, we will pay you the Final Settlement Value.
Final Settlement Value:	If the Reference Return is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, equal to the lesser of: (a) $1,000 + ($1,000 × Reference Return × Upside Participation Rate); and (b) $1,000 + ($1,000 × Maximum Cap). If the Reference Return is less than or equal to zero but greater than or equal to the Buffer Level, you will receive $1,000 per $1,000 Principal Amount of securities (zero return). If the Reference Return is less than the Buffer Level, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, calculated as follows: $1,000 + [$1,000 × (Reference Return + 10%)]. Under these circumstances, you will lose 1% of the Principal Amount of your securities for each percentage point that the Reference Return is below the Buffer Level. For example, because the buffer protects the first 10% of loss, if the Reference Return is -20%, you will suffer a 10% loss and receive 90% of the Principal Amount. If the Reference Return is less than the Buffer Level, you may lose up to 90% of your investment.
Reference Return:	The quotient, expressed as a percentage, calculated as follows:
	Final Price – Initial Price Initial Price
Buffer Level:	-10%
Initial Price:	$1,699.00, which was the Official Closing Price of the Reference Asset on the Pricing Date.
Final Price:	The Official Closing Price of the Reference Asset on the Final Valuation Date.

GENERAL

This pricing supplement relates to an offering of securities linked to the Reference Asset identified on the cover page. The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to a single Reference Asset. Although the offering of securities relates to the Reference Asset identified on the cover page, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the Reference Asset or any component security included in the Reference Asset or as to the suitability of an investment in the securities.

You should read this document together with the prospectus dated April 2, 2009, the prospectus supplement dated April 9, 2009 and the product supplement dated April 9, 2009. All references to “Enhanced Market Participation Notes” in the accompanying product supplement shall refer to these Accelerated Market Participation Securities. If the terms of the securities offered hereby are inconsistent with those described in the accompanying product supplement, prospectus supplement or prospectus, the terms described in this pricing supplement shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-6 of this pricing supplement, page PS-4 of the product supplement and page S-3 of the prospectus supplement, as the securities involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities. As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, a prospectus supplement and a product supplement) with the SEC for the offering to which this pricing supplement relates. Before you invest, you should read the prospectus, prospectus supplement and product supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering. You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov. Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and product supplement if you request them by calling toll-free 1-866-811-8049.

PAYMENT AT MATURITY

On the Maturity Date, for each security you hold, we will pay you the Final Settlement Value, which is an amount in cash, as described below:

If the Reference Return is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, equal to the lesser of:

(a) $1,000 + ($1,000 × Reference Return × Upside Participation Rate); and

(b) $1,000 + ($1,000 × Maximum Cap).

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

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

$1,000 + [$1,000 × (Reference Return + 10%)].

Under these circumstances, you will lose 1% of the Principal Amount of your securities for each percentage point that the Reference Return is below the Buffer Level. For example, because the buffer protects the first 10% loss, subject to the credit risk of HSBC, if the Reference Return is -20%, you will suffer a 10% loss and receive 90% of the Principal Amount. You should be aware that if the Reference Return is less than the Buffer Level, you may lose up to 90% of your investment.

Interest

The securities will not pay periodic interest.

PS-4

Calculation Agent

We or one of our affiliates will act as calculation agent with respect to the securities.

INVESTOR SUITABILITY

The securities may be suitable for you if:		The securities may not be suitable for you if:

PS-5

RISK FACTORS

We urge you to read the section “Risk Factors” on page S-3 in the accompanying prospectus supplement and on page PS-4 of the accompanying product supplement. Investing in the securities is not equivalent to investing directly in the Reference Asset. You should understand the risks of investing in the securities and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the securities in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and product supplement including the explanation of risks relating to the securities described in the following sections:

}	“— Risks Relating to All Note Issuances” in the prospectus supplement;

}	“— Additional Risks Relating to Notes with a Reference Asset That is a Commodity or a Contract or Index Relating thereto” in the prospectus supplement.

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

Your investment in the securities may result in a loss.

You will be exposed to the decline in the Final Price from the Initial Price beyond the Buffer Level of -10%. Accordingly, if the Reference Return is less than -10%, your Payment at Maturity will be less than the Principal Amount of your securities. You may lose up to 90% of your investment at maturity if the Reference Return is negative.

The appreciation on the securities is limited by the Maximum Cap.

You will not participate in any appreciation in the price of the Reference Asset (as magnified by the Upside Participation Rate) beyond the Maximum Cap of 22.00%. You will not receive a return on the securities greater than the Maximum Cap.

Credit risk of HSBC USA Inc.

The securities are senior unsecured debt obligations of the issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the securities will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the securities, including any return of principal at maturity, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the securities and, in the event HSBC were to default on its obligations, you may not receive the amounts owed to you under the terms of the securities.

The securities will not bear interest.

As a holder of the securities, you will not receive periodic interest payments.

The price of the Reference Asset may change unpredictably, affecting the value of your securities in unforeseeable and potentially negative ways.

The price of gold is primarily affected by the global demand for, and supply of, gold. The market for gold bullion is global and the price of gold is subject to volatile price movements over short periods of time and is affected by numerous factors, including macroeconomic factors such as the structure of and confidence in, the global monetary system; expectations of the future rate of inflation; the relative strength of, and confidence in, the U.S. dollar, the currency in which gold prices are generally quoted; interest rates; gold borrowing and lending rates; and global or regional economic, financial, political, regulatory, judicial or other changes or events. The price of gold may be affected by industry factors such as industrial and jewelry demand as well as lending, sales and purchases of gold by the official sector, including central banks and other governmental agencies and multilateral institutions that hold gold. Additionally, the price of gold may be affected by levels of gold production, production costs and short-term changes in supply and demand due to trading activities in the gold market. It is not possible to predict the aggregate effect of all or any combination of these factors. These factors may affect the price of the Reference Asset and, therefore, the value of your securities in varying, unpredictable and potentially negative ways. For additional information about the Reference Asset, see “Description of the Reference Asset” below.

There are certain risks relating to the Official Closing Price being determined by LGM including the membership of HSBC Bank USA, N.A. in the LGM.

Your securities are linked to the performance of gold. The Official Closing Price of gold will be determined by reference to the afternoon fixing price reported by the LGM. The LGM is the principal global clearing center for over-the-counter gold bullion transactions, including transactions in spot, forward and options contracts, together with exchange traded futures and options and other derivatives. The

PS-6

Reference Asset is traded on the LGM by the five members thereof. Although all members of the LGM are supervised by the Bank of England and are required to satisfy a capital adequacy test, the LGM itself is not a regulated entity. If the LGM should cease operations, or if bullion trading should become subject to a value added tax or other tax or any other form of regulation currently not in place, the role of LGM price fixings as a global benchmark for the value of the Reference Asset may be adversely affected. The LGM is a principals’ market which operates in a manner more closely analogous to over-the-counter physical commodity markets than regulated futures markets, and certain features of U.S. futures contracts are not present in the context of LGM trading. For example, there are no daily price limits on the LGM, which would otherwise restrict fluctuations in the prices at which commodities trade on the LGM. In a declining market, it is possible that prices would continue to decline without limitation within a trading day or over a period of trading days. The LGM has no obligation to consider your interests in calculating or revising the official afternoon gold fixing. In addition, HSBC Bank USA, N.A., an affiliate of ours, is a member of the LGM. HSBC Bank USA, N.A. will have no obligation to consider your interests as a holder of the securities in determining the LGM afternoon gold fixing on any day. For additional information about the Reference Asset, see “Description of the Reference Asset” below.

Commodities are subject to uncertain legal and regulatory regimes, which may result in a hedging disruption event and a loss on your investment.

The commodity that comprises the Reference Asset is subject to legal and regulatory regimes in the United States and, in some cases, in other countries. Changes in any applicable law, regulation or rule, or interpretation of any such law, regulation or rule, that affects our hedge related to the securities could result in a Commodity Hedging Disruption Event that would allow us to accelerate the Maturity Date of the securities and cause an early repayment. If we elect to accelerate the Maturity Date because of a Commodity Hedging Disruption Event, we will pay you an amount determined in good faith and in a commercially reasonable manner by the Calculation Agent. If the payment on the securities is accelerated, your investment may result in a loss and you may not be able to reinvest your money in a comparable investment. For additional information, see “Supplemental Information Relating to the Terms of the Securities—Commodity Hedging Disruption Events” below.

The securities are not insured by any governmental agency of the United States or any other jurisdiction.

The securities are not deposit liabilities or other obligations of a bank and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or program of the United States or any other jurisdiction. An investment in the securities is subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations as they become due, you may not receive the full Payment at Maturity of the securities.

Certain built-in costs are likely to adversely affect the value of the securities prior to maturity.

While the Payment at Maturity described in this pricing supplement is based on the full Principal Amount of your securities, the original issue price of the securities includes the placement agent’s commission and the estimated cost of HSBC hedging its obligations under the securities. As a result, the price, if any, at which HSBC Securities (USA) Inc. will be willing to purchase securities from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the Maturity Date could result in a substantial loss to you. The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity.

No ownership of gold or other gold-related contracts.

As a holder of the securities, you will not receive the return you would receive if you had actually purchased gold or exchange-traded or over-the-counter instruments based on gold. You will not have any rights that holders of such assets or instruments would have.

The securities lack liquidity.

The securities will not be listed on any securities exchange. HSBC Securities (USA) Inc. is not required to offer to purchase the securities in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the securities.

Potential conflicts.

HSBC and its affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities. We will not have any obligation to consider your interests as a holder of the securities in taking any action that might affect the value of your securities.

PS-7

The Price of the Reference Asset and the value of the securities may be affected by currency exchange fluctuations.

The Official Closing Price is determined in U.S. dollars. As a result, appreciation of the U.S. dollar will increase the relative cost of the Reference Asset for foreign consumers, thereby potentially reducing demand for the Reference Asset. As a result, the price of the Reference Asset and the value of the securities may be adversely affected by changes in exchange rates between the U.S. dollar and foreign currencies. In recent years, rates of exchange between the U.S. dollar and various foreign currencies have been highly volatile, and this volatility may continue in the future. However, fluctuations in any particular exchange rate that have occurred in the past are not necessarily indicative of fluctuations that may occur during the term of the securities.

Uncertain tax treatment.

For a discussion of the U.S. federal income tax consequences of your investment in a security, please see the discussion under “U.S. Federal Income Tax Considerations” herein, the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying product supplement and the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

ILLUSTRATIVE EXAMPLES

The following table and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the price of the Reference Asset relative to its Initial Price. We cannot predict the Final Price of the Reference Asset on the Final Valuation Date. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset or return on the securities. With respect to the securities, the Final Settlement Value may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including those issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Payment at Maturity on a $1,000 investment in securities for a hypothetical range of performance for the Reference Return from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Security” as used below is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 Principal Amount of securities to $1,000. The potential returns described here assume that your securities are held to maturity. You should consider carefully whether the securities are suitable to your investment goals. The following table and examples reflect the following:

}	Principal Amount: $1,000

}	Initial Price: $1,699.00

}	Upside Participation Rate: 150%

PS-9

The following examples indicate how the Final Settlement Value would be calculated with respect to a hypothetical $1,000 investment in the securities.

Example 1: The price of the Reference Asset increases from the Initial Price of $1,699.00 to a Final Price of $1,783.95


Reference Return:	5.00%
Final Settlement Value:	$1,075.00

Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is less than the Maximum Cap, the Final Settlement Value would be $1,100.00 per $1,000 Principal Amount of securities calculated as follows:

$1,000 + ($1,000 × Reference Return × Upside Participation Rate)

= $1,000 + ($1,000 × 5.00% × 150%)

= $1,075.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by 150% when such Reference Return is positive and is equal to or less than the Maximum Cap.

Example 2: The price of the Reference Asset increases from the Initial Price of $1,699.00 to a Final Price of $2,038.80.


Reference Return:	20.00%
Final Settlement Value:	$1,220.00

Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is greater than the Maximum Cap, the Final Settlement Value would be $1,220.00 per $1,000 Principal Amount of securities calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 22.00%)

= $1,220.00

Example 2 shows that you will receive the return of your principal investment plus a return equal to the Maximum Cap when the Reference Return is positive and if such Reference Return multiplied by 150% exceeds the Maximum Cap.

Example 3: The price of the Reference Asset decreases from the Initial Price of $1,699.00 to a Final Price of $1,614.05.


Reference Return:	-5.00%
Final Settlement Value:	$1,000.00

Because the Reference Return is less than zero but greater than the Buffer Level, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount of securities (a zero return).

Example 4: The price of the Reference Asset decreases from the Initial Price of $1,699.00 to a Final Price of $1,019.40.


Reference Return:	-40.00%
Final Settlement Value:	$700.00

Here, the Reference Return is -40.00%. Because the Reference Return is less than the Buffer Level of -10%, the Final Settlement Value would be $700.00 per $1,000 Principal Amount of securities calculated as follows:

$1,000 + [$1,000 × (Reference Return + 10%)]

= $1,000 + [$1,000 × (-40.00% + 10%)]

= $700.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the price of the Reference Asset beyond the Buffer Level of -10%. YOU MAY LOSE UP TO 90% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

PS-10

DESCRIPTION OF THE REFERENCE ASSET

The Official Closing Price of gold will be determined as the price of one troy ounce of gold, stated in U.S. dollars, as set by the five members of the London Gold Market Fixing Ltd. (the “LGM”) during the afternoon gold price fixing which starts at 3:00 p.m. London, England time, and displayed on Reuters page “GOFO”, as determined by the calculation agent.

The LGM is the principal global clearing center for over-the-counter gold bullion transactions, including transactions in spot, forward and options contracts, together with exchange traded futures and options and other derivatives.

Twice daily during London trading hours there is a “fixing” which provides reference gold prices for that day’s trading. Formal participation in the London fixing is traditionally limited to the five members of the LGM. These members meet each London business day via telephone at 10:30 A.M., to determine the London A.M. fixing price and at 3:00 p.m., to determine the London P.M. fixing price. The five members of the LGM are currently The Bank of Nova Scotia—ScotiaMocatta, HSBC Bank USA, N.A., Deutsche Bank AG London, Société Générale Corporate & Investment Banking and Barclays Capital. The fixing chairmanship rotates annually amongst these members. During each session, clients place orders with the dealing rooms of fixing members, who net all orders before communicating the net interest to their representative at the fixing. The gold price is then adjusted up and down until sell and buy orders are matched, at which point the price is declared “fixed” and all orders are executed on the basis of that price. Customers may be kept advised of price changes, together with the level of interest, while the fixing is in progress and may cancel, increase or decrease their interest dependent upon this information.

In addition to the LGM, over-the counter trading in gold occurs globally, on a twenty-four hour basis on the basis of the gold spot price. LGM fixing prices are influenced by trades settled using the gold spot price in over-the-counter trades conducted in markets other than the LGM, and the LGM fixing prices influence the quotes based on the gold spot price. Gold spot prices are quoted by various dealers and media sources.

Historical Performance of the Reference Asset

The following graph sets forth the historical performance of the Reference Asset based on the historical London P.M. fixing prices from November 22, 2006 through November 22, 2011. The London P.M. fixing price for the Reference Asset on November 22, 2011 was $1,699.00. We obtained the London P.M. fixing prices below from Bloomberg Professional® service. We make no representation or warranty as to the accuracy or completeness of the information obtained from Bloomberg Professional® service.

The historical Official Closing Prices of the Reference Asset should not be taken as an indication of future performance, and no assurance can be given as to the Final Price. We cannot give you assurance that the performance of the Reference Asset will result in the return of any of your initial investment.

SUPPLEMENTAL INFORMATION RELATING TO THE TERMS OF THE SECURITIES

Market Disruption Events

If any day on which the Official Closing Price of the Reference Asset is to be determined (a “valuation date”) is not a scheduled trading day with respect to the Reference Asset, then the valuation date will be the next day that is a scheduled trading day. If a market disruption event (as defined below) exists on a valuation date, then the Official Closing Price for such valuation date will be determined by the Calculation Agent in good faith and in its sole discretion. If the Final Valuation Date is postponed, then the Maturity Date will also be postponed by an equal number of business days following the postponed Final Valuation Date and no interest will be paid in respect of such postponement.

“Market disruption event” means any day on which a condition specified in (a)—(d) below exists and which the calculation agent determines is material:

(a)

the LGM fails to determine or publish its London P.M. fixing price;

(b)

any suspension of or limitation imposed on trading, whether by reason of movements in price exceeding limits or otherwise, (A) relating to the Reference Asset on the LGM or (B) in futures or options contracts relating to the Reference Asset on any exchange or trading market for such contracts;

(c)

any event that disrupts or impairs (as determined by the calculation agent) the ability of market participants (A) to effect transactions in, or obtain market values for, the Reference Asset or (B) to effect transactions in, or obtain market values for, any futures or options contracts relating to the Reference Asset, on any exchange or trading market for such contracts; or

(d)

any other event as determined by the calculation agent that materially interferes with the ability of the issuer or any of its affiliates to unwind all or a portion of a hedge with respect to the securities that the issuer or its affiliates have effected or may effect as described under “Selected Risk Considerations — Potential Conflicts” above.

“Scheduled trading day” means any day on which the LGM is scheduled to determine and publish its London P.M. fixing price.

Commodity Hedging Disruption Events

If a Commodity Hedging Disruption Event occurs, we shall have the right to accelerate the Maturity Date of the securities and cause an early repayment by written notice to the trustee at its New York office no later than one business day immediately following the day on which such Commodity Hedging Disruption Event occurred. The Calculation Agent shall determine on the date of such notice the amount due on such early acceleration in good faith in a commercially reasonable manner. We will pay such amount on the fifth business day following the day on which the Calculation Agent delivers notice of such acceleration to the trustee. We will provide, or will cause the calculation agent to provide, written notice to the trustee at its New York office, on which notice the trustee may conclusively rely, and to DTC, of the cash amount due with respect to the securities no later than two business days prior to the date on which such payment is due.

A “Commodity Hedging Disruption Event” means that due to (i) the adoption of, or any change in, any applicable law, regulation or rule or (ii) the promulgation of, or any change in, the interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law, rule, regulation or order (including, without limitation, as implemented by the CFTC or any exchange or trading facility), in each case occurring on or after the pricing date, the calculation agent determines in good faith that it is contrary to such law, rule, regulation or order to purchase, sell, enter into, maintain, hold, acquire or dispose of our or our affiliates’ (A) positions or contracts in securities, options, futures, derivatives or foreign exchange or (B) other instruments or arrangements, in each case, in order to hedge individually or in the aggregate on a portfolio basis our obligations under the securities (“hedge positions”), including, without limitation, if such hedge positions are (or, but for the consequent disposal thereof, would otherwise be) in excess of any allowable position limit(s) in relation to any commodity traded on any exchange(s) or other trading facility (it being within the sole and absolute discretion of the calculation agent to determine which of the hedge positions are counted towards such limit).

Discontinuance or Modification of the Reference Asset; Alteration of Method of Calculation

If (i) the LGM discontinues trading in the Reference Asset or (ii) there is a material modification in the content, composition or constitution of the Reference Asset, and if the calculation agent determines that the LGM or any other market trades a successor or substitute commodity or contract that is substantially similar to the Reference Asset, then in each case that commodity or contract (the “successor asset”) will replace the Reference Asset.

If the calculation agent determines that no successor asset exists, the calculation agent will determine the relevant Official Closing Prices on any scheduled trading day and the Final Price (as applicable). If a successor asset is selected by the calculation agent, that successor asset will be used as a substitute for the original Reference Asset for all purposes, including for purposes of determining the relevant Official Closing Prices on any scheduled trading day, the Final Price and whether a market disruption event exists. In this circumstance, the calculation agent may choose to determine the Official Closing Prices and the Final Price by reference to a single price source or multiple price sources. This choice may be affected by a number of factors, including whether the market(s) for the successor asset trade continuously, centrally fix prices and/or announce closing prices.

If the calculation agent determines that the method of calculating the price of the Reference Asset used by the LGM has been modified in any material respect, then the calculation agent will (i) make such adjustments to the relevant Official Closing Prices on any scheduled trading day, the Final Price and any other terms of the securities as it considers necessary to account for the economic effect of such modification and (ii) determine the Payment at Maturity with reference to the terms of the securities as adjusted.

In each of the foregoing events, the relevant Official Closing Prices on any scheduled trading day and the Final Price may be different than it would have been if the original Reference Asset had not been discontinued or modified. Thus, discontinuation or modification of the Reference Asset may adversely affect the value of the securities.

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the securities from HSBC for distribution to other registered broker dealers or will offer the securities directly to investors. HSBC Securities (USA) Inc. will offer the securities at the offering price set forth on the cover page of this pricing supplement and will receive underwriting discounts and commissions of 1.00%, or $10.00, per $1,000 Principal Amount of securities.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

There is no direct legal authority as to the proper tax treatment of the securities, and therefore significant aspects of the tax treatment of the securities are uncertain as to both the timing and character of any inclusion in income in respect of the securities. Under one approach, the securities should be treated as pre-paid forward or other executory contracts with respect to the Reference Asset. We intend to treat the securities consistent with this approach. Pursuant to the terms of the securities, you agree to treat the securities under this approach for all U.S. federal income tax purposes. Notwithstanding any disclosure in the accompanying product supplement to the contrary, our special U.S. tax counsel in this transaction is Sidley Austin llp. 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, Sidley Austin llp, it is reasonable to treat the securities as pre-paid forward or other executory contracts with respect to the Reference Asset. Pursuant to this approach, we do not intend to report any income or gain with respect to the securities prior to their 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 security for more than one year at such time for U.S. federal income tax purposes. Additionally, it is possible that the Internal Revenue Service could assert that the securities should be treated as giving rise to “collectibles” gain or loss if you hold your securities for more than one year, although we do not think such a treatment would be appropriate in this case because a sale or exchange of the securities is not a sale or exchange of a collectible but is rather a sale or exchange of a pre-paid forward or other executory contract that reflects the value of a collectible. “Collectibles” gain is currently subject to tax at marginal rates of up to 28%.

For a discussion of the U.S. federal income tax consequences of your investment in a security, please see the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying product supplement and the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.
