TO OUR SHAREHOLDERS

The Municipal Market Environment
During the six months ended January 31, 2000, continued strong
domestic growth, gradual improvement in foreign economies and
investor concerns regarding future inflationary pressures pushed
long-term fixed-income bond yields higher. The Federal Reserve Board
continued to raise short-term interest rates in August and November
1999 as well as just after the period's close, seeking to moderate
US economic growth and maintain the existing benign inflationary
environment. US economic growth, in part intensified by Year 2000
preparations, grew 5.8% during the last fiscal quarter of 1999 and
had an annual rate of 4.1% for 1999. A number of inflationary
indicators have also begun to signal some increase in price
pressures.

However, most investors believe that the Federal Reserve Board will
be extremely vigilant in preventing such pressures from any material
escalation. US Treasury bond yields responded by rising
approximately 60 basis points (0.60%) by mid-January 2000. A strong
rally, largely based upon an expected significant reduction in the
future supply of US Treasury 30-year maturity bonds, pushed yields
lower to 6.50% at January 31, 2000. Over the last six months, yields
on 30-year US Treasury bonds rose approximately 40 basis points.

The tax-exempt bond market was also under pressure throughout the
entire period. Despite receiving more than $30 billion in coupon
payments, bond maturities and proceeds from early redemptions in
December and January, overall investor demand has diminished. It is
likely that the returns generated by the US equity market have
continued to attract investor attention and have left little demand
for competing investment alternatives. At January 31, 2000, the long-
term tax-exempt revenue bond yield, as measured by the Bond Buyer
Revenue Index, was 6.34%, an increase of nearly 70 basis points over
the last six months.

Issuance by municipalities has significantly declined in recent
months. Over the last six months, less than $100 billion in long-
term tax-exempt bonds were issued, representing a decline of over
20% compared to the same period a year ago. During the last three
months, less than $45 billion in long-term bonds were issued by
various municipalities. This most recent quarterly issuance is 30%
below the level of the January 31, 1999 quarter. Additionally,
during January 2000, less than $8 billion in municipal debt was
underwritten, down more than 50% from January 1999 levels. This
represents the lowest monthly issuance in over five years. Toward
the end of 1999, consensus estimates for 2000 annual issuance were
in the $210 billion--$215 billion range. January's underwritings, as
well as those expected to be issued in the near future, have led
some analysts to revise their forecasts to the $190 billion range.

We believe an overall reduction in bond supply in the coming year
should help support the municipal bond market's overall technical
position. While tax-exempt bond yields, which are at their highest
level in over three years, have attracted significant retail
investor interest, institutional demand declined sharply. Long-term
municipal mutual funds have seen consistent outflows in recent
months as the yields of individual securities rose faster than those
of larger, more diverse mutual funds. During the six months ended
January 31, 2000, tax-exempt mutual funds have had net redemptions
of approximately $9 billion. Also, the demand from property and
casualty insurance companies has weakened as a result of the losses
and anticipated losses incurred from a series of damaging storms
across much of the eastern United States. Additionally, many
institutional investors who have in recent years been attracted to
the municipal bond market by historically attractive tax-exempt bond
yield ratios of over 90%, found other asset classes even more
attractive. Even with a reduced supply position, tax-exempt issuers
have been forced to repeatedly raise municipal bond yields in an
attempt to attract adequate demand. We believe a reduced bond supply
going forward is likely to promote a more closely balanced
supply/demand structure and foster a more stable tax-exempt interest
rate environment.

Looking ahead, it appears to us that long-term tax-exempt bond
yields will remain under pressure, trading in a broad range centered
around current levels. Investors are also likely to remain concerned
regarding future action by the Federal Reserve Board in early 2000.
Any improvement in bond prices may be contingent upon weakening in
both US employment growth and consumer spending. The 100 basis point


Merrill Lynch New Mexico Municipal Bond Fund
January 31, 2000


rise in US Treasury bond yields seen thus far could negatively
affect US economic growth. The US housing market is likely to be
among the first sectors to be affected, as some declines have
already been evidenced because of higher mortgage rates. We believe
it is also unrealistic to expect double-digit returns in US equity
markets to continue indefinitely. Much of the US consumer's wealth
is tied to recent stock market appreciation. Any slowing in these
incredible growth rates may reduce consumer spending. We believe
that these factors suggest that the worst of the recent increase in
bond yields has passed and stable, if not slightly improving, bond
prices may be expected.


Portfolio Strategy
During the six months ended January 31, 2000, we initially retained
a defensive position toward the municipal bond market, then
gradually moved to a neutral stance. We accomplished this shift by
swapping bonds with shorter maturties and/or higher coupons for
bonds with longer maturities and/or lower coupons. Our strategy has
been to seek to enhance income and to take advantage of the highest
absolute municipal yields. During the period, we also sought to
capitalize on market discrepancies, caused in part by Year 2000
concerns, as we purchased bonds we believed to be undervalued
combined with selling bonds we believed to be overvalued.

New Mexico bond issuance was comparatively light during the six-
month period ended January 31, 2000, particularly in the second
half. New Mexico bond prices remained relatively firm compared to
the national level because of the light issuance. However, the light
issuance presented us with fewer opportunities within the municipal
bond market.

Looking ahead, we intend to remain fully invested in the municipal
market in an effort to enhance shareholder income. We do not expect
to significantly alter our present stance toward the market given
the current economic backdrop. We will continue to take advantage of
any opportunities in the municipal marketplace that we believe is
appropriate.


In Conclusion
We appreciate your ongoing interest in Merrill Lynch New Mexico
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

Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers four pricing
alternatives:

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

* Class B Shares are subject to a maximum contingent deferred sales
  charge of 4% if redeemed during the first year, decreasing 1% each
  year thereafter to 0% after the fourth year. 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 D Shares after approximately 10 years. (There is no initial
  sales charge for automatic share conversions.)

* 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.

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

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Recent Performance
Results" and "Average Annual Total Return" 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. The Fund's Investment Adviser voluntarily waived a
portion of its management fee. Without such waiver, the Fund's
performance would have been lower.

Merrill Lynch New Mexico Municipal Bond Fund
January 31, 2000


NOTES TO FINANCIAL STATEMENTS



1. Significant Accounting Policies:
Merrill Lynch New Mexico Municipal Bond Fund (the "Fund") is part of
Merrill Lynch Multi-State Municipal Series Trust (the "Trust"). The
Fund is registered under the Investment Company Act of 1940 as a non-
diversified, open-end management investment company. The Fund's
financial statements are prepared in accordance with generally
accepted accounting principles, 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 four classes of shares under the
Merrill Lynch Select Pricing SM System. Shares of Class A and Class
D are sold with a front-end sales charge. Shares of Class B and
Class C 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 B,
Class C and Class D 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. The following is a summary of significant accounting
policies followed by the Fund.

(a) Valuation of investments--Municipal bonds and other portfolio
securities in which the Fund invests are traded primarily in the
over-the-counter municipal bond and money markets and are valued at
the last available bid price in the over-the-counter market or on
the basis of 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 remaining maturities 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 strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* 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
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.

(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 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). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

January 31, 2000


(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. Distributions in excess
of realized capital gains are due primarily to differing tax
treatments for futures transactions and post-October losses.


2. Investment Advisory Agreement and Transac-
tions 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 also entered into a Distribution
Agreement and Distribution Plans with Merrill Lynch Funds
Distributor ("MLFD" or the "Distributor"), a division of Princeton
Funds Distributor, Inc. ("PFD"), 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 January 31, 2000, FAM earned fees of
$24,969, of which $18,160 was voluntarily waived.

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 ongoing account maintenance and distribution
fees. The fees are accrued daily and paid monthly at annual rates
based upon the average daily net assets of the shares as follows:

                                     Account
                                   Maintenance  Distribution
                                       Fee           Fee

Class B                               .25%           .25%
Class C                               .25%           .35%
Class D                               .10%            --

Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML &
Co., also provides account maintenance and distribution services to
the Fund. The ongoing account maintenance fee compensates the
Distributor and MLPF&S for providing account maintenance services to
Class B, Class C and Class D shareholders. The ongoing distribution
fee compensates the Distributor and MLPF&S for providing shareholder
and distribution-related services to Class B and Class C
shareholders.

For the six months ended January 31, 2000, MLFD earned underwriting
discounts and MLPF&S earned dealer concessions on sales of the
Fund's Class A Shares as follows:

                                MLFD      MLPF&S

Class A                          $1        $21

For the six months ended January 31, 2000, MLPF&S received
contingent deferred sales charges of $6,991 and $923 relating to
transactions in Class B and Class C Shares, respectively.

Financial Data Services, Inc., a wholly-owned subsidiary of ML &
Co., is the Fund's transfer agent.

Accounting services are provided to the Fund by FAM at cost.
