FWP-7

RISK FACTORS

We urge you to read the section “Risk Factors” on page S-3 in the accompanying prospectus supplement, on page PS-4 of the accompanying product supplement and on page US1-1 of underlying supplement no. 1.  Investing in the securities is not equivalent to investing directly in any of the stocks comprising 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 advisers, of the suitability of the securities in light of your particular financial circumstances and the information set forth in this free writing prospectus and the accompanying underlying supplement, product supplement, prospectus supplement and prospectus.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement, product supplement and underlying 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 an Equity Security or Equity Index as the Reference Asset” in the prospectus supplement; and

} “— Securities Prices Generally are Subject to Political, Economic, Financial and Social Factors that Apply to the Markets in Which They Trade and, to a Lesser Extent, Foreign Markets” in the underlying supplement no. 1.

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 Level from the Initial Level.  Accordingly, if the Reference Return is less than zero, your Payment at Maturity will be less than the Principal Amount of your securities.  You may lose up to 100% 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 level of the Reference Asset (as magnified by the Upside Participation Rate) beyond the Maximum Cap. You will not receive a return on the securitiesgreaterthan 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. Any payment to be made on the securities 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 level 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.

Changes that affect the FTSETM 100 Index will affect the market sevel of the securities and the amount you will receive at maturity.

The policies of the reference sponsor of the FTSETM 100 Index concerning additions, deletions and substitutions of the constituents comprising the FTSETM 100 Index and the manner in which the reference sponsor takes account of certain changes affecting those constituents included in the FTSETM 100 Index may affect the level of the FTSETM 100 Index.  The policies of the reference sponsor with respect to the calculation of the FTSETM 100 Index could also affect the level of the FTSETM 100 Index.  The reference sponsor may discontinue or suspend calculation or dissemination of the FTSETM 100 Index.  Any such actions could affect the level of the securities.

Please read and pay particular attention to the section “Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset” in the accompanying prospectus supplement.

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. This debt is not guaranteed under the Federal Deposit Insurance Corporation’s Temporary Liquidity Guarantee Program.

FWP-8

Changes in the level of the FTSETM 100 Index and changes in the exchange rate between the British pound sterling and the U.S. dollar may offset each other.

Movements in the level of the FTSETM 100 Index and movements in the exchange rate between the British pound sterling and the U.S. dollar may not correlate with each other. Even if the level of the FTSETM 100 Index increases, the exchange rate between the British pound sterling and the U.S. dollar may change such that the Final Level decreases as compared to the Initial Level, and vice versa.  Therefore, in calculating the Reference Return, increases or decreases in the level of the FTSETM 100 Index may be moderated, or wholly offset, by increases or decreases in the exchange rate between the British pound sterling and the U.S. dollar.

There are risks associated with foreign securities markets.

Because stocks or companies included in the FTSETM 100 Index are publicly traded in the United Kingdom and are denominated in British pounds sterling, investments in the notes involve particular risks.  For example, the foreign securities markets may be more volatile than the United States securities markets, and market developments may affect these markets differently from the United States or other securities markets.  Direct or indirect government intervention to stabilize the securities markets outside the United States, as well as cross-shareholdings in certain companies, may affect trading prices and trading volumes in those markets.  Also, the public availability of information concerning foreign issuers may vary depending on their home jurisdiction and the reporting requirements imposed by their respective regulators.  In addition, the foreign issuers may be subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to United States reporting companies.

Securities prices generally are subject to political, economic, financial and social factors that apply to the markets in which they trade and, to a lesser extent, foreign markets.  

Securities prices outside the United States are subject to political, economic, financial and social factors that apply in foreign countries.  These factors, which could negatively affect foreign securities markets, include the possibility of changes in a foreign government’s economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities and the possibility of fluctuations in the rate of exchange between currencies.  Moreover, foreign economies may differ favorably or unfavorably from the United States economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

Exposure to fluctuations in exchange rates.

Your return on the securities, if any, will be adjusted for exchange rate fluctuations between the British pound sterling, which is the currency in which the stocks included in the FTSETM 100 Index are based, and the U.S. dollar.  If the British pound sterling appreciates or depreciates relative to the U.S. dollar over the term of the securities, you may receive additional payment or incur a reduction in Payment at Maturity due to such fluctuation.  The Initial Level and Final Level will be determined by reference to the level of the FTSETM 100 Index as denominated in British pounds sterling, converted into U.S. dollars by multiplying it by the Spot Rate on such date.  As a result, you will have foreign currency exposure, and the level of your securities will be affected by exchange rate fluctuations between the British pound sterling and the U.S. dollar.  If the British pound sterling appreciates or depreciates relative to the U.S. dollar over the term of the securities, the level of your securities may increase or decrease at maturity irrespective of the Reference Return.

Currency markets may be volatile.

Currency markets may be highly volatile. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time. Foreign currency rate risks include, but are not limited to, convertibility risk and market volatility and potential interference by foreign governments through regulation of local markets, foreign investment or particular transactions in foreign currency. These factors may affect the level of the British pound sterling on the Pricing Date or the Final Valuation Date, and therefore, the level of your securities.

Legal and regulatory risks.

Legal and regulatory changes could adversely affect exchange rates. In addition, many governmental agencies and regulatory organizations are authorized to take extraordinary actions in the event of market emergencies. It is not possible to predict the effect of any future legal or regulatory action relating to exchange rates, but any such action could cause unexpected volatility and instability in currency markets with a substantial and adverse effect on the performance of the British pound sterling on the Pricing Date or on the Final Valuation Date and, consequently, the level of the securities.

If the liquidity of the British pound sterling is limited, the level of the securities would likely be impaired.

Currencies and derivatives contracts on currencies may be difficult to buy or sell, particularly during adverse market conditions. Reduced liquidity on the Pricing Date or on the Final Valuation Date wouldlikely have an adverse effect on the Spot Rate, and therefore, on the return on your securities. Limited liquidity relating to the British pound sterling may also result in HSBC USA Inc., as

FWP-9

calculation agent, being unable to determine the Initial Level or Final Level using its normal means. The resulting discretion by the calculation agent in determining the Reference Return could, in turn, result in potential conflicts of interest.

We have no control over the exchange rate between the British pound sterling and the U.S. dollar.

 Foreign exchange rates can either float or be fixed by sovereign governments. Exchange rates of the currencies used by most economically developed nations are permitted to fluctuate in level relative to the U.S. Dollar and to each other. However, from time to time governments may use a variety of techniques, such as intervention by a central bank, the imposition of regulatory controls or taxes or changes in interest rates to influence the exchange rates of their currencies. Governments may also issue a new currency to replace an existing currency or alter the exchange rate or relative exchange characteristics by a devaluation or revaluation of a currency. These governmental actions could change or interfere with currency valuations and currency fluctuations that would otherwise occur in response to economic forces, as well as in response to the movement of currencies across borders. As aconsequence, these government actions could adversely affect an investment in the securities which are affected by the exchange rate between the British pound sterling and the U.S. dollar.

The Spot Rate will not take into account all developments in the British pound sterling or the FTSETM 100 Index.

Changes in the British pound sterling and the FTSETM 100 Index during the term of the securities other than on the Pricing Date or Final Valuation Date may not be reflected in the calculation of the Payment at Maturity. Generally, the calculation agent will calculate the Initial Level and Final Level by multiplying the level and Official Closing Level, respectively, of the FTSETM 100 Index by the Spot Rate on such date, as described above. The Final Level will be calculated only as of the Final Valuation Date. As a result, the Reference Return may be negativelyaffectedeven if the Spot Rate or the FTSETM 100 Index had moved favorably at certain times during the term of the securities before moving to an unfavorable level on the Final Valuation Date.

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

While the Payment at Maturitydescribed in this free writing prospectus 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 couldresult 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.

Lack of 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. In addition, we are an affiliate of one of the companies that make up the FTSETM 100 Index.  We will not have any obligation to consider your interests as a holder of the securities in taking any action that might affect the FTSETM 100 Index and therefore level of your securities.

Uncertain tax treatment.

For a discussion of certain 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” below, 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 level of the Reference Asset relative to its Initial Level.  We cannot predict the Final Level 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, and the hypothetical Initial Level used in the illustrations below is not the actual Initial Level of the Reference Asset to which your securities are linked.  You should not take these examples as an indication or assurance of the expected performance ofthe Reference Asset.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 examples below have been rounded for ease of analysis.

The table below illustrates the PaymentatMaturity on a $1,000 investment in securities for a hypothetical range of performances for the Reference Return from -100% to +100%. The following results are based solely on the assumptions outlined below. 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 numbers appearing in the table below have been rounded for ease of analysis. You should not take the below illustration as an indication or assurance of the expected performance of the Reference Asset or return of the securities.

The following table and examples assume the following:

·	Principal Amount:	$1,000
·	Upside Participation Rate:	500%
·	Hypothetical Initial Level:	7,800 (assuming a Spot Rate of 1.5 and a value of the FTSETM 100 Index on the Pricing Date of 5,200.  The actual Initial Level will be determined on the Pricing Date, and will be based upon the actual Spot Rate and the actual level of the FTSETM 100 Index on the Pricing Date, as determined by the calculation agent.)
·	Hypothetical Maximum Cap:	40.5% (the midpoint of the range of 35.5% to 45.5%, to be determined on the Pricing Date)

FWP-11

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 Official Closing Level of the FTSETM 100 Index on the Final Valuation Date is 5,300 and the Spot Rate at such time is 1.5453.  The Final Level is 8,190, calculated as follows:

(5,300 × 1.5453) = 8,190

Because the Initial Level is 7,800 and the Final Level is 8,190, the Reference Return is 5.00%, calculated as follows:

(8,190 - 7,800) / 7,800 = 5.00%

	Reference Asset
Initial Level	7,800
Final Level	8,190
Reference Return	5.00%
Final Settlement Value:	$1,250.00

Here, the Reference Return is 5.00%.  Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is less than the hypothetical Maximum Cap, the Final Settlement Value would be $1,250.00 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% × 500%)

= $1,250.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by 500% when the Reference Return is positive and if such amount is equal to or less than the Maximum Cap.  In this example, even though the Official Closing Level of the FTSETM 100 Index increased over the term of the securities by only 1.92%, the Reference Return is 5.00% and your return on the securities is 25.00% due to the decrease of the Spot Rate from the Pricing Date to the Final Valuation Date.

Example 2:  The Official Closing Level of the FTSETM 100 Index on the Final Valuation Date is 5,100 and the Spot Rate at such time is 1.6824.  The Final Level is 8,580, calculated as follows:

(5,100 × 1.6824) = 8,580

Because the Initial Level is 7,800 and the Final Level is 8,580, the Reference Return is 10.00%, calculated as follows:

(8,580 - 7,800) / 7,800 = 10.00%

	Reference Asset
Initial Level	7,800
Final Level	8,580
Reference Return	10.00%
Final Settlement Value:	$1,405.00

Here, the Reference Return is 10.00%.  Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is greater than the hypothetical Maximum Cap, the Final Settlement Value would be $1,405.00 per $1,000 Principal Amount of securities calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 40.50%)

= $1,405.00

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 500% exceeds the Maximum Cap.  In this example, even though Official Closing Level of the FTSETM 100 Index decreased over the term of the securities by -1.92%, due to a decrease in the Spot Rate from the Pricing Date to the Final Valuation Date, the Reference Return is 10.00%.  However, because the Reference Return multiplied by 500% exceeds the Maximum Cap, under these circumstances, your return is your return on the securities is limited to the Maximum Cap on the notes of 40.50%.

Example 3:  The Official Closing Level of the FTSETM 100 Index on the Final Valuation Date is 5,300 and the Spot Rate at such time is 1.0302.  The Final Level is 5,460, calculated as follows:

(5,300 × 1.0302) = 5,460

Because the Initial Level is 7,800 and the Final Level is 5,460, the Reference Return is -30.00%, calculated as follows:

FWP-12

(5,460 - 7,800) / 7,800 = -30.00%

	Reference Asset
Initial Level	7,800
Final Level	5,460
Reference Return	-30.00%
Final Settlement Value:	$700.00

Here, the Reference Return is - -30.00%.  Because the Reference Return is less than the zero, the Final Settlement Value would be $700.00 per $1,000 Principal Amount of securities calculated as follows:

$1,000 + [$1,000 × Reference Return]

= $1,000 + [$1,000 × (-30.00%)]

= $700.00

Example 3 shows that you are exposed to a 1% loss to your Principal Amount for each percentage point that the Reference Return is below zero.  YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES IF THE REFERENCE RETURN IS NEGATIVE. In this example, even though the Official Closing Level of the FTSETM 100 Index increased over the term of the securities by 1.92%, due to an increase in the Spot Rate from the trade date to the final date, the reference return is -30.00%.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale 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. Proposes to offer the securities at the offering price set forth on the cover page of this free writing prospectus and will receive underwriting discounts and commissions of between 0.35% and 0.50%, or between $3.50 and $5.00, per $1,000 Principal Amount of securities.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the securities, but is under no obligation to do so and may discontinue any market-making activities at any time without notice.

See “Supplemental Plan of Distribution” on page S-52 in the prospectus supplement.

We expect that delivery of the securities will be made against payment for the securities on or about the Settlement Date set forth in this free writing prospectus, which is expected to be the fifth business day following the Trade Date of the securities. Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade securities on Trade Date and the next succeeding business day, will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult theirown advisers.

CERTAIN 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 orexchange 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.

We will not attempt to ascertain whether any of the entities whose stock is included in the Reference Asset would be treated as a passive foreign investment company (“PFIC”), as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the Reference Asset 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 Reference Asset and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Reference Asset is or becomes a PFIC.

For a discussion of certain 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.
