TO OUR SHAREHOLDERS
The Municipal Market Environment
Long-term tax-exempt bond yields declined slightly during the six months ended
August 31, 1998. Throughout most of this year, foreign economic factors have
continued to outweigh US domestic fundamentals. Thus far this year, the near
absence of inflationary pressures in the United States continued to support low
interest rates. Consistently strong domestic economic growth has caused some
investors to fear that the Federal Reserve Board would be forced eventually to
raise short-term interest rates. Such action would be taken to ensure that the
US economy's present rate of growth would decelerate before any inflationary
pressures could develop. However, the weakening financial conditions in many
Asian countries, combined with the currency devaluation in Russia, calmed
investor concerns of Federal Reserve Board intervention, and fixed-income bond
prices again moved higher. As measured by the Bond Buyer Revenue Bond Index,
long-term uninsured municipal bond yields fell approximately 10 basis points
(0.10%) to end the August quarter at 5.26%. As in late 1997 and early 1998, US
Treasury bond yields benefited from a "flight to quality" as foreign investors
were drawn to the relative safe haven of US Government securities. Additionally,
the sharp US equity market correction at the end of August triggered an
additional flight into US Treasury securities. Long-term US Treasury bond yields
declined approximately 70 basis points to end the August quarter at 5.21%.
Thus far in 1998, the municipal bond market has experienced unexpectedly strong
supply pressures. To a large extent, these supply pressures have prevented
tax-exempt bond yields from declining as much as US Treasury bond yields. During
the first six months of 1998, nearly $150 billion in new tax-exempt bonds were
underwritten, an increase of about 40% compared to the same period a year ago.
During the most recent three months, municipalities issued almost $75 billion in
new securities, an increase of nearly 25% compared to the same three-month
period in 1997.
However, the recent pace of new municipal bond issuance is unlikely to be
maintained. Continued increases in bond issuance will require lower and lower
tax-exempt bond yields to generate the economic savings necessary for additional
municipal bond refinancings. Preliminary estimates for 1998 total municipal bond
issuance are in the $200 bilion-$225 billion range. These estimates suggest that
recent supply pressures, which have lessened recently, are likely to abate later
in the year.
The continued impact of the Asian financial crisis on the US domestic economy's
future growth remains unclear. Current Asian economic conditions continue to
reflect ongoing weakness. Recent trade data indicated that reduced US exports to
these countries might have lowered US economic growth in the first half of 1998
by as much as 2%. Since further trade deterioration is likely in the coming
months, we do not believe that the Federal Reserve Board will be willing to
raise interest rates, barring a dramatic and unexpected resurgence of domestic
inflation.
These factors suggest that over the near term, interest rates in general are
unlikely to rise by any appreciable amount. Recent supply pressures have caused
municipal bond yield ratios to rise relative to US Treasury bond yields. At
August 31, 1998, long-term tax-exempt bond yields were at attractive yield
ratios relative to US Treasury securities of comparable maturities (over 90%),
well in excess of their expected range of 85%-88%. Tax-exempt bond yield ratios
rarely exceeded 90% in the 1980s and 1990s. Previous instances have usually been
associated with potential changes in Federal tax codes that would have adversely
affected the tax-favored status of municipal bonds. The present situation has
developed largely because of a temporary supply imbalance. These imbalances
should soon be corrected as tax-exempt bond issuance slows from its current
rapid pace later this year. Any further pressure on the municipal market may
well represent a very attractive investment opportunity.
Fiscal Year in Review
During the fiscal year ended August 31, 1998, the municipal marketplace was
characterized by rather restricted price movements within certain identifiable
trading ranges. A combination of several positive technical and economic factors
contributed to an environment where the fixed-income markets,
1
<PAGE>
Merrill Lynch California Insured Municipal Bond Fund August 31, 1998
particularly the tax-exempt market, reached historically low levels of nominal
interest rates.
Our strategy during the fiscal year was to strive to remain fully invested,
taking advantage of any dips in market price to position the Fund more
aggressively. The challenge over the past 12 months has been to identify which
periods constituted market retracements in an effort to concentrate the Fund's
buying power during these events, whether through the rather ample 1997-1998
new-issue calendar, or through the secondary marketplace. During April and May
1998, when such a period did arise, we utilized a temporary backup in interest
rates to position the Fund more aggressively.
Throughout the 12-month period ended August 31, 1998, we invested in
higher-yielding municipal securities that were within the Fund's credit
standards to seek to maintain an attractive level of tax-exempt income. By
fiscal year-end, with long-term municipal yields nearing 5%, we sold some of the
Fund's more aggressively structured discount securities. Proceeds of these sales
were concentrated in cash reserves or used to purchase less interest
rate-sensitive, income-oriented holdings. Although the fundamental economic
backdrop for the marketplace is still quite supportive, we would expect the
municipal market to participate only marginally in any further price gains. As a
result of these strategies, total returns for the Fund's Class A, Class B, Class
C and Class D Shares were +7.79%, +7.35%, +7.25% and +7.68%, respectively, for
the 12-month period ended August 31, 1998.
Looking ahead, we expect to follow a slightly less aggressive strategy, since
substantial future price gains are unlikely, barring a drastic change in
investor expectations regarding the performance of fixed-income securities in
the current low interest rate environment. Consequently, we expect to remain
focused on seeking to deliver a high level of current income without sacrificing
credit quality.
In Conclusion
We appreciate your investment in Merrill Lynch California Insured 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:
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 August 31, 1998
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 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.
(e) Deferred organization expenses and prepaid registration fees--Deferred
organization expenses are charged to expense on a straight-line basis over a
period not exceeding five years. 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
14
<PAGE>
Merrill Lynch California Insured Municipal Bond Fund August 31, 1998
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 &

Distribution Agreement and Distribution Plans with Merrill Lynch Funds
Distributor ("MLFD" or "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. For the year ended August 31, 1998, FAM earned fees of $502,296, of
which $6,357 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:
- --------------------------------------------------------------------------------

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner

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.

charges of $93,829 and $8,328 relating to transactions in Class B and Class C
Shares, respectively.
