Summary

The four charts below provide a summary of the Notes, including Note characteristics and risk considerations as well as an illustrative diagram and table reflecting hypothetical returns at maturity.   These charts should be reviewed together with the disclosure regarding the Notes contained in this free writing prospectus as well as in the accompanying Equity Index Underlying Supplement, prospectus and prospectus supplement.

The following charts illustrate the hypothetical total return at maturity on the Notes. The “total return” as used in this free writing prospectus is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 Principal Amount of Notes to $1,000. The hypothetical total returns set forth below reflect the hypothetical Initial Level of 2,500.00, the Knock-Out Buffer Amount of 30.00%, and the Contingent Minimum Return on the Notes of 7.30%. The hypothetical total returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following table and examples have been rounded for ease of analysis.

Selected Purchase Considerations

· APPRECIATION POTENTIAL — The Notes provide the opportunity to participate in the appreciation of the Reference Asset at maturity. If a Knock-Out Event has not occurred, in addition to the Principal Amount, you will receive at maturity at least the Contingent Minimum Return on the Notes of 7.30%, or a minimum Payment at Maturity of $1,073.00 for every $1,000 Principal Amount of Notes. Because the Notes are our senior unsecured debt obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.

· THE CONTINGENT MINIMUM RETURN APPLIES ONLY IF A KNOCK-OUT EVENT HAS NOT OCCURRED — If a Knock-Out Event has not occurred, you will receive at least the Principal Amount and the Contingent Minimum Return at maturity, even if the Final Level is below the Initial Level. If a Knock-Out Event has occurred, you will lose 1.00% of your Principal Amount for every 1.00% that the Final Level is less than the Initial Level. If a Knock-Out Event has occurred and the Reference Return is -100.00%, you will lose your entire investment.

· DIVERSIFICATION OF THE EURO STOXX 50^® INDEX — The return on the Notes is linked to the EURO STOXX 50^® Index. The EURO STOXX 50^® Index consists of 50 component stocks from the Eurozone. For additional information about the Reference Asset, see the information set forth under “The EURO STOXX 50^® Index” in the Equity Index Underlying Supplement.

· TAX TREATMENT — There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one approach, the Notes should be treated as pre-paid executory contracts with respect to the Reference Asset. We intend to treat the Notes consistent with this approach. Pursuant to the terms of the Notes, you agree to treat the Notes 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, Morrison & Foerster LLP, it is reasonable to treat the Notes as pre-paid 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 Notes prior to their maturity or an earlier sale or exchange and we generally 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 Note for more than one year at such time for U.S. federal income tax purposes.

For a further discussion of the U.S. federal income tax consequences related to the Notes, see the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

Selected Risk Considerations

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in any of the component securities of the Reference Asset. These risks are explained in more detail in the “Risk Factors” sections of the accompanying Equity Index Underlying Supplement and prospectus supplement.

· YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — The Notes do not guarantee any return of principal. The return on the Notes at maturity is linked to the performance of the Reference Asset and will depend on whether a Knock-Out Event has occurred and whether, and the extent to which, the Reference Return is positive or negative. If the Official Closing Level is ever below the Initial Level by a percentage that is more than the Knock-Out Buffer Amount of 30%, a Knock-Out Event will have occurred, and the benefit provided by the Knock-Out Buffer Amount will terminate. IF A KNOCK-OUT EVENT OCCURS, YOU MAY LOSE UP TO 100.00% OF YOUR INVESTMENT.

· THE NOTES ARE SUBJECT TO THE CREDIT RISK OF HSBC USA INC. — The Notes 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 Notes 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 Notes, 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 Notes 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 Notes.

· SUITABILITY OF THE NOTES FOR INVESTMENT — You should only reach a decision to invest in the Notes after carefully considering, with your advisors, the suitability of the Notes in light of your investment objectives and the information set out in this free writing prospectus. Neither HSBC nor any dealer participating in the offering makes any recommendation as to the suitability of the Notes for investment.

· YOUR ABILITY TO RECEIVE THE CONTINGENT MINIMUM RETURN MAY TERMINATE AT ANY TIME DURING THE TERM OF THE NOTES — If the Official Closing Level is ever below the Initial Level during the Observation Period by a percentage that is more than the Knock-Out Buffer Amount of 30%, you will be fully exposed to the depreciation in the Reference Asset and will not be entitled to receive the benefit provided by the Contingent Minimum Return on the Notes. Under these circumstances, if the Final Level is less than the Initial Level on the Final Valuation Date, you will lose 1.00% of the Principal Amount of your investment for every 1.00% decrease in the Final Level as compared to the Initial Level. You will be subject to this potential loss of principal even if the level of the Reference Asset subsequently increases such that the Official Closing Level is less than the Initial Level by not more than the Knock-Out Buffer Amount of 30%, or is equal to or greater than the Initial Level. As a result, you may lose some or all of your investment. Your return on the Notes may not reflect the return you would receive on a conventional fixed or floating rate debt instrument with a comparable term to maturity issued by HSBC or any other issuer with a similar credit rating.

· CERTAIN BUILT-IN COSTS ARE LIKELY TO ADVERSELY AFFECT THE VALUE OF THE NOTES PRIOR TO MATURITY — While the Payment at Maturity described in this free writing prospectus is based on the full Principal Amount of your Notes, the original issue price of the Notes includes the placement agent’s commission and the estimated cost of hedging our obligations under the Notes through one or more of our affiliates. As a result, the price, if any, at which HSBC Securities (USA) Inc. will be willing to purchase Notes from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale of Notes by you prior to the Maturity Date could result in a substantial loss to you. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

· NO INTEREST OR DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the Notes, you will not receive interest payments, and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of securities composing the Reference Asset would have.

· THE NOTES LACK LIQUIDITY — The Notes will not be listed on any securities exchange. HSBC Securities (USA) Inc. may offer to purchase the Notes in the secondary market but is not required to do so and may cease making such offers at any time if at all. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the Notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily.

· POTENTIAL CONFLICTS — HSBC and its affiliates play a variety of roles in connection with the issuance of the Notes, including acting as and hedging obligations under the Notes. In performing these duties, the economic interests of the and other affiliates of are potentially adverse to your interests as an investor in the Notes. under no obligation to consider your interests as a holder of the Notes in taking any

· The Notes are Not Insured by any Governmental Agency of the United States or any Other Jurisdiction — The Notes are not deposit liabilities or other obligations of a bank and are not insured or guaranteed 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 Notes 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 Notes.

· MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES — In addition to the level of the Reference Asset on any day, the value of the Notes will be affected by a number of economic and market factors that may either offset or magnify each other, including:

· the expected volatility of the Reference Asset;

· the time to maturity of the Notes;

· whether a Knock-Out Event has occurred;

· the dividend rate on the equity securities underlying the Reference Asset;

· interest and yield rates in the market generally;

· a variety of economic, financial, political, regulatory or judicial events that affect the Reference Asset or the stock markets generally; and

· our creditworthiness, including actual or anticipated downgrades in our credit ratings.

What Is the Total Return on the Notes at Maturity Assuming a Range of Performances for the Reference Asset?

The following table illustrates the hypothetical total return at maturity on the Notes. The “total return” as used in this free writing prospectus is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 Principal Amount of Notes to $1,000. The hypothetical total returns set forth below reflect the Knock-Out Buffer Amount of 30% and the Contingent Minimum Return on the Notes of 7.30% and assume an Initial Level of 2,500.00. The actual Initial Level will be determined on the Pricing Date. The hypothetical total returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following table and examples have been rounded for ease of analysis.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Total Return
5,000.00	100.00%	100.00%
4,500.00	80.00%	80.00%
4,250.00	70.00%	70.00%
3,750.00	50.00%	50.00%
3,500.00	40.00%	40.00%
3,250.00	30.00%	30.00%
3,000.00	20.00%	20.00%
2,750.00	10.00%	10.00%
2,682.50	7.30%	7.30%
2,625.00	5.00%	7.30%
2,500.00	0.00%	7.30%
2,375.00	-5.00%	7.30%
2,250.00	-10.00%	7.30%
2,125.00	-15.00%	7.30%
2,000.00	-20.00%	7.30%
1,750.00	-30.00%	7.30%
1,500.00	-40.00%	-40.00%
1,250.00	-50.00%	-50.00%
1,000.00	-60.00%	-60.00%
500.00	-80.00%	-80.00%
0.00	-100.00%	-100.00%

Hypothetical Examples of Amounts Payable at Maturity

The following examples illustrate how the total returns set forth in the table above are calculated.

Example 1: The level of the Reference Asset decreases from the hypothetical Initial Level of 2,500.00 to a Final Level of 2,250.00. Because a Knock-Out Event has not occurred and the Reference Return of -10.00% is less than the Contingent Minimum Return of 7.30%, the investor benefits from the Contingent Minimum Return and receives a Payment at Maturity of $1,073.00 per $1,000 Principal Amount of Notes, calculated as follows:

$1,000 + ($1,000 × 7.30%) = $1,073.00

Example 2: The level of the Reference Asset increases from the hypothetical Initial Level of 2,500.00 to a Final Level of 2,750.00. Because the Reference Return of 10.00% is positive and greater than the Contingent Minimum Return of 7.30%, the investor receives a Payment at Maturity of $1,100.00 per $1,000 Principal Amount of Notes, calculated as follows:

$1,000 + ($1,000 × 10.00%) = $1,100.00

Example 3: A Knock-Out Event has occurred, and the level of the Reference Asset decreases from the hypothetical Initial Level of 2,500.00 to a Final Level of 1,500.00. Because a Knock-Out Event has occurred and the Reference Return is -40.00%, the investor is exposed to the negative performance of the Reference Asset and receives a Payment at Maturity of $600.00 per $1,000 Principal Amount of Notes, calculated as follows:

$1,000 + ($1,000 × -40.00%) = $600.00
