PR-2

Payment at Maturity

On the maturity date, for each note, we will pay you the cash settlement value, which is an amount in cash based on the reference return, as described below:

· If a trigger event has occurred, you will receive a cash payment on the maturity date that will reflect the performance of the reference asset. Under these circumstances, your payment at maturity per $1,000 principal amount note will be calculated as follows:

$1,000 + ($1,000 x Reference Return);

If a trigger event has occurred and the final level is less than the initial level, you will lose some or all of your investment. This means that if the reference return is -100.00%, you will lose your entire investment; and

· If a trigger event has not occurred, you will receive a cash payment on the maturity date that will reflect the performance of the reference asset, subject to the contingent minimum return. If a trigger event has not occurred, your payment at maturity per $1,000 principal amount note will equal $1,000 plus the product of (a) $1,000 multiplied by (b) the greater of (i) the reference return and (ii) the contingent minimum return.

Trigger Event

A trigger event occurs if, at any time during the observation period, the reference level is less than the barrier level.

Interest

The notes will not bear interest.

Expenses

We estimate that we will spend approximately $5,000 for printing, trustee and legal fees and other expenses allocable to the offerings for each offering of notes.

Calculation Agent

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

Reference Sponsor

Standard & Poor’s is the reference sponsor.

INVESTOR SUITABILITY

The notes may be suitable for you if: ¨    You believe the level of the reference asset will increase or decrease moderately—meaning that you believe the level of the reference asset will not decline below the barrier level at any time during the observation period. ¨    You are willing to make an investment that is exposed to downside performance of the reference asset on a 1 to 1 basis in the event that a trigger event occurs. ¨    You are willing to forego dividends paid on the stocks included in the reference asset. ¨    You do not seek current income from this investment. ¨    You do not seek an investment for which there is an active secondary market. ¨    You are willing to hold the notes to maturity.     The notes may not be suitable for you if: ¨    You believe the level of the reference asset will decline below the barrier level at any time during the observation period. ¨    You are unwilling to make an investment that is exposed to downside performance of the reference asset on a 1 to 1 basis in the event that a trigger event occurs. ¨    You seek an investment that is 100% principal protected. ¨    You prefer the lower risk, and therefore accept the potentially lower returns, of fixed income investments with comparable maturities issued by HSBC or another issuer with a similar credit rating. ¨    You prefer to receive the dividends paid on any stocks included in the reference asset. ¨    You seek current income from this investment. ¨    You seek an investment for which there will be an active secondary market. ¨    You are unable or unwilling to hold the notes to maturity.

PR-3

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 product supplement.  Investing in the notes is not equivalent to investing directly in the reference asset or the securities comprising the reference asset.  You should understand the risks of investing in the notes and should reach an investment decision only after careful consideration, with your advisers, of the suitability of the notes in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying prospectus supplement, product supplement and prospectus.

As you review “Risk Factors” in the accompanying prospectus supplement, you should pay particular attention to the following sections:

· “— Risks Relating to All Note Issuances”; and

· “— Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset.”

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

The Notes are Not Fully Principal Protected and Your Protection May Terminate at Any Time During the Observation Period.

If the reference level at any time during the observation period declines below the barrier level, you will at maturity be fully exposed to any decline in the level of the reference asset. Under these circumstances, if the final level is less than the initial level, you will lose 1% of the principal amount of your investment for every 1% 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 reference asset subsequently increases such that the reference level is greater than the barrier 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.

Your Ability to Receive the Contingent Minimum Return may Terminate at Any Time During the Observation Period.

If the reference level at any time during the observation period declines below the barrier level, you will not be entitled to receive the protection provided by the contingent minimum return on the notes. Under these circumstances, you may lose some or all of your investment at maturity and will be fully exposed to any decline in the level of the reference asset.

Whether a Trigger Event Occurs is Based on Intra-Day Levels of the Reference Asset, Not Only Closing Levels of the Reference Asset.

The reference level, which is used to determine whether a trigger event has occurred, is based on intra-day levels of the reference asset, not only closing levels of the reference asset.  Therefore, because the intra-day low levels may be less than or equal to the closing levels, it is more likely that a trigger event will occur than if the reference level were based solely on closing levels of the reference asset.

The Notes will not be Listed on any Securities Exchange or Quotation System.

One of our affiliates intends to offer to purchase the notes in the secondary market but is not required to do so. 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 one of our affiliates is willing to buy the notes.

The Notes will not Bear Interest.

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

PR-4

Changes that Affect the Reference Asset Will Affect the Market Value of the Notes and the Amount You Will Receive at Maturity.

The policies of the publisher, sponsor or compiling authority for the reference asset (the “reference sponsor”) concerning additions, deletions and substitutions of the constituents included in the reference asset and the manner in which the reference sponsor takes account of certain changes affecting those constituents included in the reference asset may affect the level of the reference asset.  The policies of the reference sponsor with respect to the calculation of the reference asset could also affect the level of the reference asset.  The reference sponsor may discontinue or suspend calculation or dissemination of the reference asset.  Any such actions could affect the value of the notes.

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 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 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 the Issuer, and in the event that the Issuer is unable to pay its obligations as they become due, you may not receive the full payment at maturity of the notes. This debt is not guaranteed under the Federal Deposit Insurance Corporation’s Temporary Liquidity Guarantee Program.

Uncertain Tax Treatment.

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

ILLUSTRATIVE EXAMPLES

The following 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.  You should not take these examples as an indication or assurance of the expected performance of the reference asset.With respect to the notes, the cash 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 following examples indicate how the cash settlement value would be calculated with respect to a hypothetical $1,000 investment in the notes.  These examples assume the notes are held to maturity, an initial level of 794.35, a barrier level of 397.18, and a contingent minimum return of 33.00%.

Example 1:  A trigger event has not occurred, and the level of the reference asset increases from the initial level of 794.35 to a final level of 953.22.

	Reference Asset
Initial Level	794.35
Final Level	953.22
Reference Return	20.00%
Cash Settlement Value:	$1,330.00

Here, the reference return is 20.00%.

Because a trigger event has not occurred, the cash settlement value equals the principal amount of the note plus the product of (a) the principal amount multiplied by (b) the greater of (1) the reference return and (2) the contingent minimum return.  Accordingly, at maturity, the cash settlement value in this example would equal $1,000.00 plus (a) $1,000.00 multiplied by (b) 33.00%.  Therefore, the notes would pay $1,330.00 at maturity.

PR-5

Example 1 shows that you are assured the return of your principal investment plus no less than the contingent minimum return when a trigger event has not occurred.

Example 2:  A trigger event has not occurred, and the level of the reference asset decreases from the initial level of 794.35 to a final level of 675.20.

	Reference Asset
Initial Level	794.35
Final Level	675.20
Reference Return	-15.00%
Cash Settlement Value:	$1,330.00

Here, the reference return is -15.00%.

Because a trigger event has not occurred, the cash settlement value equals the principal amount of the note plus the product of (a) the principal amount multiplied by (b) the greater of (1) the reference return and (2) the contingent minimum return.  Accordingly, at maturity, the cash settlement value in this example would equal $1,000.00 plus (a) $1,000.00 multiplied by (b) 33.00%.  Therefore, the notes would pay $1,330.00 at maturity.

Example 2 illustrates how you are protected by the contingent minimum return in the event that the reference return is negative but no trigger event has occurred.

Example 3:  A trigger event has not occurred, and the level of the reference asset increases from the initial level of 794.35 to a final level of 1,112.09.

	Reference Asset
Initial Level	794.35
Final Level	1,112.09
Reference Return:	40.00%
Cash Settlement Value:	$1,400.00

Here, the reference return is 40.00%.

Because a trigger event has not occurred, the cash settlement value equals the principal amount of the note plus the product of (a) the principal amount multiplied by (b) the greater of (1) the reference return and (2) the contingent minimum return.  Accordingly, at maturity, the cash settlement value in this example would equal $1,000.00 plus (a) $1,000.00 multiplied by (b) 40.00%.  Therefore, the notes would pay $1,400.00 at maturity.

Example 3 shows that where the reference return is greater than the contingent minimum return, you will participate in the full positive performance of the reference asset and receive a return at maturity greater than the contingent minimum return.

PR-6

Example 4:  A trigger event has occurred, and the level of the reference asset decreases from the initial level of 794.35 to a final level of 714.92.

	Reference Asset
Initial Level	794.35
Ending level	714.92
Reference Return:	-10.00%
Cash Settlement Value:	$900.00

Here, the reference return is -10.00%.

Because a trigger event has occurred, you will participate fully in the performance of the reference asset over the term of the notes.  Accordingly, at maturity, the cash settlement value would be equal to $900.00, and you would suffer a loss of 10.00% of your principal amount.

Example 4 shows that you may lose some or all of the principal amount of your notes if a trigger event occurs and the reference return is negative.

PR-7

Sensitivity Analysis – Hypothetical payment at maturity for each $10,000 principal amount of notes.

The table below illustrates the payment at maturity (including, where relevant, the payment in respect of the reference return) on a $10,000 investment in notes 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.  You should consider carefully whether the notes 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 notes.

Assumptions:

· Principal Amount: $10,000

· Initial Level: 794.35

· Barrier Level: 397.18, equal to 50.00% of the Initial Level

· Contingent Minimum Return: 33.00%

The notes are intended to be long term investments and, as such, should be held to maturity. They are not intended to be short-term trading instruments. The price at which you will be able to sell your notes prior to maturity may be at a substantial discount from the principal amount of the notes, even in cases where the level of the reference asset has appreciated since the pricing date of the notes. The potential returns described here assume that your notes are held to maturity.

DESCRIPTION OF THE REFERENCE ASSET

General

This pricing supplement is not an offer to sell and it is not an offer to buy interests in the reference asset or any of the securities comprising the reference asset.  All disclosures contained in this pricing supplement regarding a reference asset, including its make-up, performance, method of calculation and changes in its components, where applicable, are derived from publicly available information. Neither HSBC nor any of its affiliates assumes any responsibilities for the adequacy or accuracy of information about any reference asset or any constituent included in any reference asset contained in this pricing supplement.  You should make your own investigation into each reference asset.

We urge you to read the section “Sponsors or Issuers and Reference Asset” on page S-37 in the accompanying prospectus supplement.

The S&P 500® Index

We have derived all information relating to the S&P 500® Index (the “SPX”), including, without limitation, its make-up, performance, method of calculation and changes in its components, from publicly available sources. That information reflects the policies of and is subject to change by, Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. (“S&P”).  S&P is under no obligation to continue to publish, and may discontinue or suspend the publication of the SPX at any time.

S&P publishes the SPX.

The SPX is a capitalization weighted index and is intended to provide an indication of the pattern of common stock price movement.  The calculation of the level of the SPX, discussed below in further detail, is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. As of March 18, 2009, 412 companies, or 82.40% of the reference asset, traded on the New York Stock Exchange and 88 companies, or 17.60% of the SPX, traded on The Nasdaq Stock Market.  S&P chooses companies for inclusion in the SPX with the aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the New York Stock Exchange (the “NYSE”), which S&P uses as an assumed model for the composition of the total market.

Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the market price of that company’s common stock is generally responsive to changes in the affairs of the respective industry and the market value and trading activity of the common stock of that company.  Ten main groups of companies comprise the SPX with the number of companies included in each group, as of March 18, 2009, indicated in parentheses: Industrials (59), Utilities (34), Telecommunication Services (9), Materials (29), Information Technology (75), Energy (39), Consumer Staples (41), Consumer Discretionary (79), Health Care (54) and Financials (81)..  Changes in the SPX are reported daily in the financial pages of many major newspapers, on the Bloomberg Financial Service under the symbol “SPX” and on S&P website (http://www.spglobal.com).  Information contained in the S&P website is not incorporated by reference in, and should not be considered a part of, this pricing supplement.  The SPX does not reflect the payment of dividends on the stocks included in the SPX.

Computation of the SPX

S&P currently computes the SPX as of a particular time as follows:

(i)      the product of the market price per share and the number of then outstanding shares of each component stock as determined as of that time (referred to as the “market value” of that stock);

(ii)     the market values of all component stocks as of that time are aggregated;

PR-9

(iii)    the average of the market values as of each week in the base period of the years 1941 through 1943 of the common stock of each company in a group of 500 substantially similar companies is determined;

(iv)    the mean average market values of all these common stocks over the base period are aggregated (the aggregate amount being referred to as the “base value”);

(v)     the current aggregate market value of all component stocks is divided by the base value; and

(vi)    the resulting quotient, expressed in decimals, is multiplied by ten.

While S&P currently employs the above methodology to calculate the SPX, no assurance can be given that S&P will not modify or change this methodology in a manner that may affect the performance of the SPX.

S&P adjusts the foregoing formula to offset the effects of changes in the market value of a component stock that are determined by S&P to be arbitrary or not due to true market fluctuations.

These changes may result from causes such as:

•      the issuance of stock dividends,

•      the granting to shareholders of rights to purchase additional shares of stock,

•      the purchase of shares by employees pursuant to employee benefit plans,

•      consolidations and acquisitions,

•      the granting to shareholders of rights to purchase other securities of the company,

•      the substitution by S&P of particular component stocks in the SPX, and

•      other reasons.

In these cases, S&P first recalculates the aggregate market value of all component stocks, after taking account of the new market price per share of the particular component stock or the new number of outstanding shares of that stock or both, as the case may be, and then determines the new base value in accordance with the following formula:

Old Base Value  X  New Market Value  = New Base Value

Old Market Value

The result is that the base value is adjusted in proportion to any change in the aggregate market value of all component stocks resulting from the causes referred to above to the extent necessary to negate the effects of these causes upon the SPX.

In addition, S&P standard practice is to remove all closely held shares and shares held between corporations who are both in the calculations of the SPX and an SPX component’s market value.
