Merrill Lynch New York Municipal Bond Fund                        March 31, 2003

TO OUR SHAREHOLDERS

Effective April 14, 2003, the share class names for the Merrill Lynch family of
mutual funds were changed to be consistent with the standard share classes of
most other mutual fund families. As of that date, all Class A Shares were
redesignated Class I Shares. At the same time, Class D Shares were redesignated
Class A Shares. There are no changes to the Class B or Class C share class
labels. Trading symbols have not changed nor have current eligibility rules or
pricing structures. This redesignation of share classes does not impact your
investment in any way. Although the redesignation took effect just after the
close of the Fund's period, we have provided Fund performance as of March 31,
2003 to reflect the new share class designations.

The Municipal Market Environment

During the six-month period ended March 31, 2003, amid considerable monthly
volatility, long-term fixed income interest rates rose slightly. Bolstered by an
unexpected decline in the national unemployment rate to 5.6% in early October,
U.S. equity markets staged a strong rally throughout much of the month. The
Standard & Poor's 500 (S&P 500) Index rose over 8% for October triggered by
stronger-than-expected earnings reports from a large number of companies, such
as General Electric Company, International Business Machines Corporation and
Microsoft Corporation. As they have throughout most of the period, bond prices
traded in an inverse relationship to equity prices. Consequently, as stocks
rallied, bond yields rose sharply in October, despite generally weak economic
releases. During October, the U.S. housing sector remained quite robust, but
retail sales and industrial production slowed. Fixed income bond yields remained
under pressure in November as U.S. equity markets continued to strengthen.
During November, the S&P 500 Index rose an additional 5.5%. Equity prices were
supported by further signs of U.S. economic recovery, especially improving labor
market activity. In late November, third quarter 2002 gross domestic product
growth was 4%, well above the second quarter 2002 rate of 1.3%. Financial
conditions were also strengthened by a larger-than-expected reduction in
short-term interest rates by the Federal Reserve Board in early November. The
Federal Funds target rate was lowered 50 basis points (.50%) to 1.25%, its
lowest level since the 1960s. This action by the Federal Reserve Board was
largely viewed as being taken to bolster the sputtering U.S. economic recovery.
Rebounding U.S. equity markets and the prospects for a more substantial U.S.
economic recovery pushed long-term U.S. Treasury yield levels to 5.10% by late
November.

However, into early 2003, softer equity prices and renewed investor concerns
about U.S. military action against Iraq and nuclear tensions in North Korea
again pushed bond prices higher. Reacting to disappointing holiday sales and
corporate managements' attempts to scale back analysts' expectation of future
earnings, the S&P 500 Index declined more than 10% from December 2002 to
February 2003. Fearing an eventual U.S./Iraq military confrontation in 2003,
investors again sought the safety of U.S. Treasury obligations and the prices of
fixed income issues rose. By the end of February 2003, U.S. Treasury bond yields
declined approximately 40 basis points to 4.67%.

Bond yields continued to fall into early March. However, once direct U.S.
military action against Iraq began, bond yields quickly rose. Prior uncertainty
surrounding the Iraqi situation was obviously removed and early U.S. military
successes fostered the hope that the conflict would be quickly and positively
concluded. Concurrently, the S&P 400 Index rose over 6% as investors, in part,
sold fixed income issues to purchase equities in anticipation of a strong U.S.
economic recovery once the Iraqi conflict was resolved. By mid-March, U.S.
Treasury bond yields rose above 5%. However, as there was growing sentiment that
hostilities may not be resolved in a matter of weeks, U.S. Treasury bond yields
again declined to end the period at 4.81%. Over the past six months, U.S.
Treasury bond yields have risen approximately 15 basis points.

For the six months ended March 31, 2003, long-term tax-exempt bond yields also
rose modestly. Yield volatility was reduced relative to that seen in U.S.
Treasury issues as municipal bond prices were much less sensitive to worldwide
geopolitical pressures on a daily and weekly basis. Tax-exempt bond yields
generally followed their taxable counterparts higher,

responding to a more positive, or at least less negative, U.S. equity
environment and the expectation of stronger economic growth later this year.
After rising approximately 25 basis points this past October and November 2002
to 5.30%, municipal bond yields generally declined through February 2003. At
February 28, 2003, long-term tax-exempt revenue bond yields, as measured by the
Bond Buyer Revenue Bond Index, fell to approximately 5.05%. However, similar to
U.S. Treasury bond yields, once military action began in Iraq, municipal bond
yields rose sharply to nearly 5.20%. Over the past six months, long-term
tax-exempt bond yields rose approximately 12 basis points, slightly less than
U.S. Treasury obligations.

A number of factors have combined to generate consistently strong demand for
municipal bonds throughout the six-month period ended March 31, 2003. Declining
U.S. equity markets have supported continued positive demand for tax-exempt
products as investors sought the relative security of fixed income issues. Also,
with tax-exempt money market rates near 1%, the demand for longer maturity
municipal issues has increased as investors have opted to buy longer maturity
issues rather than remain in cash reserves. Additionally, investors renewed
approximately $30 billion in January 2003 from bond maturities, coupon income
and proceeds from early redemptions. However, these positive demand factors were
not totally able to offset the increase in tax-exempt new-issue supply. Recent
yield advancements have served to make municipal bonds a particularly attractive
purchase relative to their taxable counterparts. Throughout most of the yield
curve, municipal bonds have been able to be purchased at yields near or
exceeding those of comparable U.S. Treasury issues. Compared to their recent
historical averages of 82% - 88% of U.S. Treasury yields, municipal bond yields
ratios in their current 95% - 105% range are likely to prove attractive to
long-term investors.

Declining U.S. equity markets and escalating geopolitical pressures have
resulted in reduced economic activity and consumer confidence. It is important
to note that, despite all the negative factors impeding the growth of U.S.
businesses, the U.S. economy still grew at an approximate 2.5% rate for all of
2002, twice that of 2001. Similar expansion is expected for early 2003. However,
until both Iraqi and North Korean conflicts are resolved, any meaningful
increase in interest rates is unlikely.

Some analysts expect that, upon successful resolution of these conflicts, U.S.
business conditions will quickly improve. Bond yields, especially U.S. Treasury
securities, which have enjoyed a significant safe-haven benefit, are also
expected to quickly rise. Certainly, the brief spike in bond yields upon initial
military action against Iraq earlier this month demonstrated how rapidly
interest rates may respond to reduced uncertainty and a more positive financial
environment. However, it is questionable to expect that even a quick, positive
closure to these hostilities would restore business and investor confidence to
the extent that U.S. economic growth would dramatically explode and engender
associated, large-scale interest rate increases. The resumption of solid
economic growth is likely to be a gradual process accompanied by equally
graduated increases in bond yields. Moderate economic growth, within a content
of negligible inflationary pressures, should not greatly endanger the positive
fixed income environment tax-exempt products currently enjoy.

Specific to New York, the state currently faces a significant structural budget
imbalance and difficult budget balancing decisions. There is an estimated budget
gap of $2.2 billion for the current fiscal year and $9.3 billion for next year.
In fiscal year 2003, additional budget cuts were implemented, resulting in an
estimated ending General Fund balance of $716 million. Strategies to reduce the
fiscal-year 2003 budget disparity were centered primarily on the use of reserves
and a hold on spending. The state's Budget Stabilization Fund, which is included
in the General Fund, is projected to end fiscal-year 2003 at $710 million. The
governor's office has publicly disclosed that the securitization of tobacco
settlement revenues will play an important part in helping to reduce the state's
deficit. The state is seeking to issue a total of up to $4.2 billion in tobacco
settlement revenue bonds that also would include


                                                                               2


Merrill Lynch New York Municipal Bond Fund                        March 31, 2003

an additional pledge of mortgage-recording tax revenue. However, any
tobacco-backed bonds would require state legislature approval.

Portfolio Strategy

For the six-month period ended March 31, 2003, the Fund's Class A, Class B,
Class C and Class I Shares had total returns of +0.01%, -0.28%, -0.24% and
- -0.02%, respectively. The Fund's unmanaged benchmark, the Lehman Brothers
Municipal Bond Index, had a total return of +1.20% for the same 12-month period.
(Investment results shown do not reflect sales charges and would be lower if
sales charges were included. Complete performance information can be found on
pages 4 and 5 of this report to shareholders.)

During the six-month period ended March 31, 2003, we focused on seeking to
enhance the Fund's dividend stream and reducing the Fund's net asset value
volatility. Market volatility was expected as a result of conflicting economic
signals and the likelihood for a war with Iraq. Reducing asset value volatility
generally involves lowering the Fund's interest rate sensitivity. This strategy
worked well in January 2003 as interest rates rose from near historic lows.
Since then, interest rates have generally moved lower because of economic
weakness, an unstable stock market and the outbreak of war. As interest rates
fell further, we shifted the Fund to a more defensive position. While this
strategy may have been implemented a bit early, it is our belief that interest
rates do not have much further to fall.

In Conclusion

We appreciate your ongoing interest in Merrill Lynch New York Municipal Bond
Fund, and we look forward to assisting you with your financial needs in the
months and years ahead.

PERFORMANCE DATA

About Fund Performance

Effective April 14, 2003, Class A Shares were redesignated Class I Shares and
Class D Shares were redesignated Class A Shares. Investors are able to purchase
shares of the Fund through multiple pricing alternatives:

o     Class A Shares incur a maximum initial sales charge of 4% and an account
      maintenance fee of 0.10% (but no distribution fee).

o     Effective December 1, 2002, Class B Shares are subject to a maximum
      contingent deferred sales charge of 4%, declining to 0% after six years.
      All Class B Shares purchased prior to December 1, 2002 will maintain the
      four-year schedule. In addition, Class B Shares are subject to a
      distribution fee of 0.25% and an account maintenance fee of 0.25%. These
      shares automatically convert to Class A Shares after approximately ten
      years. (There is no initial sales charge for automatic share conversions.)

o     Class C Shares are subject to a distribution fee of 0.35% and an account
      maintenance fee of 0.25%. In addition, Class C Shares are subject to a 1%
      contingent deferred sales charge if redeemed within one year of purchase.

o     Class I Shares incur a maximum initial sales charge (front-end load) of 4%
      and bear no ongoing distribution or account maintenance fees. Class I
      Shares are available only to eligible investors.

None of the past results shown should be considered a representation of future
performance. Performance results do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Figures shown in each of the following tables assume reinvestment of all
dividends and capital gains distributions at net asset value on the payable
date. Investment return and principal value of shares will fluctuate so that
shares, when redeemed, may be worth more or less than their original cost.
Dividends paid to each class of shares will vary because of the different levels
of account maintenance, distribution and transfer agency fees applicable to each
class, which are deducted from the income available to be paid to shareholders.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

Merrill Lynch New York Municipal Bond Fund (the "Fund") is part of the Merrill
Lynch Multi-State Municipal Series Trust (the "Trust"). The Fund is registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund's financial statements are prepared in conformity
with accounting principles generally accepted in the United States of America,
which may require the use of management accruals and estimates. These unaudited
financial statements reflect all adjustments, which are, in the opinion of
management, necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal, recurring nature. The Fund
offers multiple classes of shares. Effective April 14, 2003, Class A Shares were
redesignated Class I Shares and Class D Shares were redesignated Class A Shares.
Class A and Class I Shares are sold with a front-end sales charge. Class B and
Class C Shares may be subject to a contingent deferred sales charge. All classes
of shares have identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class A, Class B and Class C Shares bear
certain expenses related to the account maintenance of such shares, and Class B
and Class C Shares also bear certain expenses related to the distribution of
such shares. Each class has exclusive voting rights with respect to matters
relating to its account maintenance and distribution expenditures. Income,
expenses (other than expenses attributable to a specific class) and realized and
unrealized gains and losses on investments are allocated daily to each class
based on its relative net assets. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds and other portfolio securities
are traded primarily in the over-the-counter municipal bond and money markets
and are valued at the last available bid price or yield equivalents as obtained
from one or more dealers that make markets in the securities. Financial futures
contracts and options thereon, which are traded on exchanges, are valued at
their settlement prices as of the close of such exchanges. Short-term
investments with a remaining maturity of sixty days or less are valued at
amortized cost, which approximates market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Trustees of
the Trust, including valuations furnished by a pricing service retained by the
Trust, which may utilize a matrix system for valuations. The procedures of the
pricing service and its valuations are reviewed by the officers of the Trust
under the general supervision of the Trustees.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies to increase or decrease the level of risk to which the
Fund is exposed more quickly and efficiently than transactions in other types of
instruments. Losses may arise due to changes in the value of the contract or if
the counterparty does not perform under the contract.

o Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or for the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

o Forward interest rate swaps -- The Fund is authorized to enter into forward
interest rate swaps for the purpose of hedging the interest rate risk on
portfolio securities. In a forward interest rate swap, the Fund and the
counterparty agree to pay or receive interest on a specified notional contract
amount, commencing on a specified future effective date, unless terminated
earlier. The value of the agreement is determined by quoted fair values received
daily by the Fund from the counterparty. When the agreement is closed, the Fund
records a realized gain or loss in an amount equal to the value of the
agreement.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to


18


Merrill Lynch New York Municipal Bond Fund                        March 31, 2003

its shareholders. Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(e) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(f) Dividends and distributions -- Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates.

(g) Expenses -- Certain expenses have been allocated to the individual funds in
the Trust on a pro rata basis based upon the respective aggregate net asset
value of each fund included in the Trust.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner. The Fund has entered into a Distribution
Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD" or the
"Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee
based upon the average daily value of the Fund's net assets at the following
annual rates: .55% of the Fund's average daily net assets not exceeding $500
million; .525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and .50% of average daily net assets in excess of $1
billion. For the six months ended March 31, 2003, FAM reimbursed the Fund in the
amount of $4,501.

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor an

party to a $500,000,000 credit agreement with Bank One, N.A. and certain other
lenders. The Fund may borrow under the credit agreement to fund shareholder
redemptions and for other lawful purposes other than for leverage. The Fund may
borrow up to the maximum amount allowable under the Fund's current prospectus
and statement of additional information, subject to various other legal,
regulatory or contractual limits. The Fund pays a commitment fee of .09% per
