TO OUR SHAREHOLDERS
The Municipal Market Environment
During most of the six months ended February 28, 1999, fixed-income investors
concentrated on the positive elements within the current economic framework. On
an annual basis, US economic growth remained modest, although it strengthened
somewhat in recent months. More important, continued weak foreign economic
growth has been seen as preventing US growth from overheating and generating
increased inflationary pressures. World commodity prices continued to decline to
their lowest level in over a decade, reinforcing the extremely positive
inflationary environment in the United States. Additionally, the Federal Reserve
Board lowered short-term interest rates in September, October and November.
These actions were taken both to ensure that US domestic economic growth would
not be negatively impacted by weak foreign demand and that US financial markets
would have adequate liquidity to offset deteriorating financial conditions in
Asia, Russia and Brazil. Despite considerable volatility, such positive factors
allowed long-term fixed-income interest rates to modestly decline into late
January 1999. During the six-month period ended February 28, 1999, US Treasury
bond yields declined almost 20 basis points (0.20%) to 5.09%, and long-term
tax-exempt revenue bond yields fell approximately 10 basis points to 5.17%, as
measured by the Bond Buyer Bond Revenue Index.
However, during February investors developed a more negative bias toward both
the prospects for US economic growth and long-term bond yields. Economic
indicators released during February did not suggest that the US economy was
materially stronger in February than it had been in January or even in late
1998. Inflationary measures, such as the consumer price index and the gross
domestic product price deflator, have continued to suggest that domestic price
pressures are nearly non-existent. The consensus among economists was that
Federal Reserve Board Chairman Alan Greenspan's Humphrey-Hawkins testimony
emphasized that the balance between moderate economic growth and low inflation
seen in recent quarters remains in place and that it was unlikely that the
Federal Reserve Board would lower or raise short-term interest rates during
1999. However, investors largely chose to ignore these interpretations and began
to anticipate that the Federal Reserve Board was likely to raise short-term
interest rates sometime during 1999. Subsequently, fixed-income bond yields rose
for the remainder of the month. In February, US Treasury bond yields rose almost
50 basis points to 5.57%, and long-term uninsured municipal revenue bond yields
rose less than 15 basis points to end the month at 5.29%. During the February
quarter, US Treasury bond yields rose 30 basis points, while long-term municipal
bond yields rose less than 5 basis points, as measured by the Bond Buyer Revenue
Index.
Throughout most of 1998, the municipal bond market's performance was impeded by
a significant increase in annual new-issue supply. However, in recent months,
the technical position of the tax-exempt market improved. This has led to the
outperformance by long-term municipal bonds seen thus far in 1999. Over the last
12 months, more than $275 billion in new long-term tax-exempt bonds was
underwritten, an increase of almost 16% compared to the same period a year ago.
As municipal bond yields declined in recent years, it has taken increasingly
lower bond yields to generate the cost savings necessary to refinance remaining
higher-couponed debt. Consequently, the rate of increases in municipal bond
issuance slowed dramatically in recent quarters. During the last six months,
over $120 billion in new tax-exempt bonds was issued, a decrease of
approximately 7% compared to the same period a year ago. During the quarter
ended February 28, 1999, less than $60 billion in new long-term municipal bonds
was underwritten, representing a decline of nearly 10% compared to the quarter
ended February 28, 1998.
The pace of tax-exempt issuance slowed further in 1999. Year-to-date issuance
was less than $33 billion, representing a decline of almost 25% compared to
January 1998's volume. Additionally, investors
1
<PAGE>
Merrill Lynch California Insured Municipal Bond Fund February 28, 1999
received over $40 billion in coupon payments, maturities and proceeds from early
redemptions in January and February. Consequently, investor demand has been
strong in recent months, easily matching, if not at times exceeding, available
supply. We will monitor this situation closely in the coming months to determine
if the supply pressures exerted in 1998 are abating and fostering a more
balanced supply/demand environment for 1999. Such an environment should allow
the tax-exempt market's performance to more closely mirror that of its taxable
counterpart.
Foreign investors have rarely been active investors in the tax-exempt bond
market since they are unable to benefit from the inherent tax advantage of
municipal securities. Consequently, the municipal bond market has not been able
to benefit from the strong "flight to quality" demand enjoyed by US Treasury
securities since late 1997. This inability has in large part resulted in
significantly smaller declines in municipal bond yields compared to US Treasury
securities. However, this has resulted in the opportunity to purchase tax-exempt
securities with yields very close to or, in some instances, exceeding those of
comparable US Treasury bonds. By February 28, 1999, long-term tax-exempt bond
yields were at 95% of US Treasury bond yields. Municipal bond yield ratios have
averaged approximately 92% for the last 12 months. During 1997, tax-exempt bond
yield ratios averaged 84%. It is likely that the combination of the annual
increase in new-issue volume and the "safe-haven" status of US Treasury
securities drove municipal bond yield ratios to their present attractive levels.
Should new volume decline and/or foreign financial markets regain stability in
1999, tax-exempt bond yield ratios could quickly return to their more historic
levels (85%-88%).
Looking ahead, the expected combination of moderate economic growth in the
United States and continued negligible inflation suggests a relatively stable
interest rate environment into early 1999. However, it is likely that foreign
financial markets will again be a critical factor in determining US bond yields.
While some Pacific Rim economies are expected to improve somewhat in 1999, the
economies of Japan and much of Europe are unlikely to show much growth in the
coming months. Also, economic problems in Russia and Brazil remain unresolved
suggesting that additional shocks to the world's financial system are possible.
On the other hand, the continued robustness of the US economy has led to some
back up in interest rates. However, at present these factors suggest that there
is little immediate risk of sustained significant increases in long-term bond
yields.
Portfolio Strategy
For the most part, the past six months have been supportive of fixed-income
investments, with interest rates remaining low in response to a positive
domestic and global inflationary picture. However, strong domestic growth
threatens to upset this scenario. As interest rates on municipal bonds attained
levels where traditional investors became less interested, we scaled back the
Fund's exposure to long-term holdings. We believe this will make the Fund less
sensitive to negative market movement should interest rates start to rise.
However, we do not expect a drastic rise in municipal interest rates, since
municipal securities are currently extremely attractive as a percentage of their
taxable counterparts, in our view.
The Fund's assets are concentrated in higher-quality municipal holdings in
response to the tight credit quality spreads existing in the marketplace.
Currently, securities rated AA and AAA by at least one of the major rating
agencies do not yield significantly less than lower-rated bonds. Therefore, at
February 28, 1999, 96% of the Fund's assets were insured and rated AAA/Aaa by
Standard & Poor's Corp./ Moody's Investors Service, Inc., respectively. Going
forward, we plan to monitor the market and signs of domestic economic slowing
for indications that it is safer to re-commit to the long-term end of the
municipal marketplace.

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:
o 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.
o 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.)
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 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.

Merrill Lynch California Insured Municipal Bond Fund February 28, 1999
NOTES TO FINANCIAL STATEMENTS
1. Significant Accounting Policies:
Merrill Lynch California Insured Municipal Bond Fund (the "Fund") is part of
Merrill Lynch California 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 on an
amortized cost basis, 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.
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 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.
14
<PAGE>
Merrill Lynch California Insured Municipal Bond Fund February 28, 1999
(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 date.
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 also entered into a
Distribution Agreement and Dis-tribution Plans with Merrill Lynch Funds
Distrib-utor ("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: 0.55% of the Fund's average daily net assets not exceeding $500
million; 0.525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and 0.50% of average daily net assets in excess of $1
billion.
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 Distribution
Maintenance Fee Fee
- --------------------------------------------------------------------------------
Class B .................................. 0.25% 0.25%
Class C .................................. 0.25% 0.35%
Class D .................................. 0.10% --
- --------------------------------------------------------------------------------
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 February 28, 1999, MLFD earned underwriting discounts
and MLPF&S earned dealer concessions on sales of the Fund's Class A and Class D
Shares as follows:
- --------------------------------------------------------------------------------
MLFD MLPF&S
- --------------------------------------------------------------------------------
Class A .................................. $ 1 $ 18
Class D .................................. $255 $20,216
- --------------------------------------------------------------------------------
For the six months ended February 28, 1999, MLPF&S received contingent deferred
sales charges of $29,186 and $1,094 relating to transactions in Class B and
Class C Shares, respectively.
Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is
the Fund's transfer agent.
Accounting services are provided to the Fund by FAM at cost.
Certain officers and/or trustees of the Fund are officers and/or directors of
FAM, PSI, FDS, PFD, and/or ML & Co.
3. Investments:
