Item 1 - Report to Shareholders


 
Welcome, Shareholder:

In this report, you'll learn about how your investment in Morgan Stanley Insured
California Municipal Securities performed during the annual period. We will
provide an overview of the market conditions, and discuss some of the factors
that affected performance during the reporting period. In addition, this report
includes the Trust's financial statements and a list of Trust investments.
 
Market forecasts provided in this report may not necessarily come to pass. There
is no assurance that the Trust will achieve its investment objective. The Trust
is subject to market risk, which is the possibility that market values of
securities owned by the Trust will decline and, therefore, the value of the
Trust's shares may be less than what you paid for them. Accordingly, you can
lose money investing in this Trust.

 
FUND REPORT

For the year ended October 31, 2004
 
MARKET CONDITIONS

 
The U.S. economy continued to expand during the Trust's fiscal year ended
October 31, 2004. However, through the spring and summer the economy hit what
Federal Reserve Board Chairman Alan Greenspan described as a "soft patch." Oil
prices almost doubled, reaching record highs, and employment growth weakened. As
a result, real gross domestic product growth that had averaged 4.3 percent in
the first half of the fiscal period slowed to 3.5 percent in the second.
 
Throughout most of the year, the Federal Reserve Open Market Committee (the
"Fed") maintained its short-term borrowing rate (the federal funds rate) at an
historic low. By April the market had begun to anticipate that the Fed would
begin to increase short-term interest rates in response to higher commodity
prices and reduced concern about the risk of deflation. In a series of three
measured moves between June and the end of October, the Fed did increase the
federal funds rate, from 1.00 to 1.75 percent.
 
Rising inflation fears led to rising bond yields from April to June. The market
reversed course in July, however, with yields falling from July through October
as investors became concerned with slower growth. Rising and falling yields
tended to offset each other over the entire period, and long-term municipal bond
yields at the end of October had changed little from where they had begun the
fiscal year. Higher short-term interest rates reduced the yield pickup for
extending to longer maturities, and the yield curve flattened.
 
The supply of new-issue municipal bonds declined by 8 percent in the first 10
months of 2004. California remained the largest issuer, accounting for 16
percent of total underwriting volume. The ratio of municipal yields to Treasury
yields, which serves as a gauge of relative performance, indicated that
municipals generally remained attractive relative to Treasuries during the
period. As a result, taxable investors such as insurance companies and hedge
funds that normally focus on other sectors of the bond market supported
municipal bond prices by "crossing over" to purchase municipal bonds.
 
California's credit outlook improved this year. The state successfully issued
Economic Recovery Bonds to fund past budget deficits. Higher tax revenues
stabilized fiscal conditions. The stronger economy led to gains in employment.
As a result, the three major credit rating agencies upgraded the state's
ratings.
 
PERFORMANCE ANALYSIS

 
The net asset value (NAV) of Morgan Stanley Insured California Municipal
Securities (ICS) moved from $15.24 to $15.35 per share during the period ended
October 31, 2004. Based on this increase plus the reinvestment of tax-free
dividends totaling $0.633 per share, ordinary dividends of $0.004 and long-term
capital gains of $0.199, the Trust's total NAV return was 6.95 percent. ICS's
value on the New York Stock Exchange (NYSE) increased from $13.83 to $13.96 per
share during the same period. Based on this change plus the reinvestment of
dividends and distributions, ICS's total market return was 7.19 percent. ICS's
share price was trading at a 9.06 percent discount to its NAV on October 31,

2004. Past performance is no guarantee of future results.
 
Monthly dividends for the fourth quarter of 2004 declared in September were
increased from $0.0525 to $0.055 per share to reflect the Trust's current and
projected earnings level. The Trust's level of undistributed net investment
income was $0.132 per share on October 31, 2004, versus $0.112 per share 12
months earlier.
 
One of our key strategies in managing the Trust was to keep its overall
interest-rate sensitivity lower than that of its benchmark index. This defensive
strategy helped performance early in the period when rates rose but had the net
effect of hampering total returns over the whole period by limiting the Trust's
participation in the rally later in the period. The Trust's duration,* adjusted
for leverage, was 8.1 years. The Trust's net assets, of $57 million were
diversified across 37 credits in 12 long-term sectors.
 
The Trust's procedure for reinvesting all dividends and distributions in common
shares is through purchases in the open market. This method helps support the
market value of the Trust's shares. In addition, we would like to remind you
that the Trustees have approved a procedure whereby the Trust may, when
appropriate, purchase shares in the open market or in privately negotiated
transactions at a price not above market value or net asset value, whichever is
lower at the time of purchase. During the 12-month period ended October 31,
2004, the Trust purchased and retired 89,800 shares of common stock at a weight
average market discount of 9.05 percent.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. Investment return, net asset value and common share market price will
fluctuate and Trust shares, when sold, may be worth more or less than their
original cost.
 
There is no guarantee that any securities mentioned will continue to perform
well or be held by the Trust in the future.
 
* A measure of the sensitivity of a bond's price to changes in interest rates,
expressed in years. Each year of duration represents an expected 1 percent
change in the price of a bond for every 1 percent change in interest rates. The
longer a bond's duration, the greater the effect of interest-rate movements on
its price. Typically, Trusts with shorter durations perform better in
rising-interest-rate environments, while Trusts with longer durations perform
better when rates decline.

Morgan Stanley Insured California Municipal Securities
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2004
 
1. Organization and Accounting Policies
 
Morgan Stanley Insured California Municipal Securities (the "Trust") is
registered under the Investment Company Act of 1940, as amended, as a
diversified, closed-end management investment company. The Trust's investment
objective is to provide current income which is exempt from both federal and
California income taxes. The Trust was organized as a Massachusetts business
trust on October 14, 1993 and commenced operations on February 28, 1994.
 
The following is a summary of significant accounting policies:
 
A. Valuation of Investments -- (1) portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized grid matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the mean between the last reported bid and
asked price. The portfolio securities are thus valued by reference to a
combination of transactions and quotations for the same or other securities
believed to be comparable in quality, coupon, maturity, type of issue, call
provisions, trading characteristics and other features deemed to be relevant.
The Trustees believe that timely and reliable market quotations are generally
not readily available for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service are more likely to approximate the
fair value of such securities; (2) futures are valued at the latest sale price
on the commodities exchange on which they trade unless it is determined that
such price does not reflect their market value, in which case they will be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees; and (3) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.
 
B. Accounting for Investments -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.
 
C. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Trust is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. Pursuant to the contract, the Trust agrees to
receive from or pay to the
 
 12

Morgan Stanley Insured California Municipal Securities
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2004 continued
 
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments known as variation margin are recorded by
the Trust as unrealized gains and losses. Upon closing of the contract, the
Trust realizes a 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.
 
D. Federal Income Tax Policy -- It is the Trust'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 and nontaxable
income to its shareholders. Accordingly, no federal income tax provision is
required.
 
E. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.
 
F. Use of Estimates -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.
 
2. Investment Management Agreement
 
Pursuant to an Investment Management Agreement, with Morgan Stanley Investment
Advisors Inc. (the "Investment Manager"), the Trust pays the Investment Manager
a management fee, calculated weekly and payable monthly, by applying the annual
rate of 0.35% to the Trust's weekly net assets.
 
3. Security Transactions and Transactions with Affiliates
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended October 31, 2004 aggregated
$17,259,156 and $19,459,950, respectively.
 
Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's
transfer agent. At October 31, 2004, the Trust had transfer agent fees and
expenses payable of approximately $3,900.
 
Effective April 1, 2004, the Trust began an unfunded Deferred Compensation Plan
(the "Compensation Plan") which allows each independent Trustee to defer payment
of all, or a portion, of the fees he receives for serving on the Board of
Trustees. Each eligible Trustee generally may elect to have the deferred amounts
credited with a return equal to the total return on one or more of the Morgan
Stanley funds that are offered as investment options under the Compensation
Plan. Appreciation/depreciation and distributions received from these
investments are recorded with an
 
                                                                              13

NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2004 continued
 
offsetting increase/decrease in the deferred compensation obligation and do not
affect the net asset value of the Trust.
 
4. Preferred Shares of Beneficial Interest
 
The Trust is authorized to issue up to 1,000,000 non-participating preferred
shares of beneficial interest having a par value of $.01 per share, in one or
more series, with rights as determined by the Trustees, without approval of the
common shareholders. The preferred shares have a liquidation value of $50,000
per share plus the redemption premium, if any, plus accumulated but unpaid
dividends, whether or not declared, thereon to the date of distribution. The
Trust may redeem such shares, in whole or in part, at the original purchase
price of $50,000 per share plus accumulated but unpaid dividends, whether or not
declared, thereon to the date of redemption.
 
Upon issuance, the Trust will be subject to certain restrictions relating to the
preferred shares. Failure to comply with these restrictions could preclude the
Trust from declaring any distributions to common shareholders or purchasing
common shares and/or could trigger the mandatory redemption of preferred shares
at liquidation value.
 
The preferred shares, entitled to one vote per share, generally vote with the
common shares but vote separately as a class to elect two Trustees and on any
matters affecting the rights of the preferred shares.
 
As of October 31, 2004, there were no preferred shares outstanding.
 
5. Common Shares of Beneficial Interest
 
Transactions in common shares of beneficial interest were as follows:
 


                                                                                        CAPITAL

6. Dividends to Common Shareholders
 
On September 28, 2004, the Trust declared the following dividends from net
investment income:
 


 AMOUNT          RECORD             PAYABLE
PER SHARE         DATE               DATE
---------   -----------------  -----------------
                         
 $0.055     November 5, 2004   November 19, 2004
 $0.055     December 10, 2004  December 23, 2004

 
7. Expense Offset
 
The expense offset represents a reduction of the custodian fees for earnings on
cash balances maintained by the Trust.
 
8. Risks Relating to Certain Financial Instruments
 
The Trust may invest a portion of its assets in residual interest bonds, which
are inverse floating rate municipal obligations. The prices of these securities
are subject to greater market fluctuations during periods of changing prevailing
interest rates than are comparable fixed rate obligations.
 
To hedge against adverse interest rate changes, the Trust may invest in
financial futures contracts or municipal bond index futures contracts ("futures
contracts").
 
These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Trust bears the risk
of an unfavorable change in the value of the underlying securities. Risks may
also arise upon entering into these contracts from the potential inability of
the counterparties to meet the terms of their contracts.
 
9. Federal Income Tax Status
 
The amount of dividends and distributions from net investment income and net
realized capital gains are determined in accordance with federal income tax
regulations which may differ from generally accepted accounting principles.
These "book/tax" differences are either considered temporary or permanent in
nature. To the extent these differences are permanent in nature, such amounts
are reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.
 
                                                                              15

As of October 31, 2004, the Trust had temporary book/tax differences primarily
attributable to book amortization of discounts on debt securities and
mark-to-market of open futures contracts and permanent book/tax differences
attributable to tax adjustments on debt securities sold by the Trust. To reflect
reclassifications arising from the permanent differences, accumulated
undistributed net investment income was charged and accumulated undistributed
net realized gain was credited $25,066.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
To the Shareholders and Board of Trustees of
Morgan Stanley Insured California Municipal Securities:
 
We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Insured California Municipal Securities (the "Trust"), including the
portfolio of investments, as of October 31, 2004, and the related statements of
operations for the year then ended and changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004, by correspondence with the custodian
and broker. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Morgan
Stanley Insured California Municipal Securities as of October 31, 2004, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America.

"independent" Trustees: Dr. Manuel H. Johnson and Joseph J. Kearns. Under

      1. STATEMENT OF PRINCIPLES

The Audit Committee of the Board is required to review and, in its sole
discretion, pre-approve all Covered Services to be provided by the Independent
Auditors to the Fund and Covered Entities in order to assure that services
performed by the Independent Auditors do not impair the auditor's independence
from the Fund.

The SEC has issued rules specifying the types of services that an independent
auditor may not provide to its audit client, as well as the audit committee's
administration of the engagement of the independent auditor. The SEC's rules
establish two different approaches to pre-approving services, which the SEC
considers to be equally valid. Proposed services either: may be pre-approved
without consideration of specific case-by-case services by the Audit Committee
("general pre-approval"); or require the specific pre-approval of the Audit
Committee or its delegate ("specific pre-approval"). The Audit Committee
believes that the combination of these two approaches in this Policy will result
in an effective and efficient procedure to pre-approve services performed by the
Independent Auditors. As set forth in this Policy, unless a type of service has
received general pre-approval, it will require specific pre-approval by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
authority has been delegated) if it is to be provided by the Independent
Auditors. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by the Audit Committee.

The appendices to this Policy describe the Audit, Audit-related, Tax and All
Other services that have the general pre-approval of the Audit Committee. The
term of any general pre-approval is 12 months from the date of pre-approval,
unless the Audit Committee considers and provides a different period and states
otherwise. The Audit Committee will annually review and pre-approve the services
that may be provided by the Independent Auditors without obtaining specific
pre-approval from the Audit Committee. The Audit Committee will add to or
subtract from the list of general pre-approved services from time to time, based
on subsequent determinations.

----------------------
(1)   This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and
      Procedures (the "Policy"), adopted as of the date above, supersedes and
      replaces all prior versions that may have been adopted from time to time.

                                       3


The purpose of this Policy is to set forth the policy and procedures by which
the Audit Committee intends to fulfill its responsibilities. It does not
delegate the Audit Committee's responsibilities to pre-approve services
performed by the Independent Auditors to management.

The Fund's Independent Auditors have reviewed this Policy and believes that
implementation of the Policy will not adversely affect the Independent Auditors'
independence.

      2. DELEGATION

As provided in the Act and the SEC's rules, the Audit Committee may delegate
either type of pre-approval authority to one or more of its members. The member
to whom such authority is delegated must report, for informational purposes
only, any pre-approval decisions to the Audit Committee at its next scheduled
meeting.

      3. AUDIT SERVICES

The annual Audit services engagement terms and fees are subject to the specific
pre-approval of the Audit Committee. Audit services include the annual financial
statement audit and other procedures required to be performed by the Independent
Auditors to be able to form an opinion on the Fund's financial statements. These
other procedures include information systems and procedural reviews and testing
performed in order to understand and place reliance on the systems of internal
control, and consultations relating to the audit. The Audit Committee will
approve, if necessary, any changes in terms, conditions and fees resulting from
changes in audit scope, Fund structure or other items.

In addition to the annual Audit services engagement approved by the Audit
Committee, the Audit Committee may grant general pre-approval to other Audit
services, which are those services that only the Independent Auditors reasonably
can provide. Other Audit services may include statutory audits and services
associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4,
etc.), periodic reports and other documents filed with the SEC or other
documents issued in connection with securities offerings.

The Audit Committee has pre-approved the Audit services in Appendix B.1. All
other Audit services not listed in Appendix B.1 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

      4. AUDIT-RELATED SERVICES

Audit-related services are assurance and related services that are reasonably
related to the performance of the audit or review of the Fund's financial
statements and, to the extent they are Covered Services, the Covered Entities or
that are traditionally performed by the Independent Auditors. Because the Audit
Committee believes that the provision of Audit-related services does not impair
the independence of the auditor and is consistent with the SEC's rules on
auditor independence, the Audit Committee may grant general pre-approval to
Audit-related services. Audit-related services include, among others, accounting
consultations related to accounting, financial reporting or disclosure matters

                                       4


not classified as "Audit services"; assistance with understanding and
implementing new accounting and financial reporting guidance from rulemaking
authorities; agreed-upon or expanded audit procedures related to accounting
and/or billing records required to respond to or comply with financial,
accounting or regulatory reporting matters; and assistance with internal control
reporting requirements under Forms N-SAR and/or N-CSR.

The Audit Committee has pre-approved the Audit-related services in Appendix B.2.
All other Audit-related services not listed in Appendix B.2 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

      5. TAX SERVICES

The Audit Committee believes that the Independent Auditors can provide Tax
services to the Fund and, to the extent they are Covered Services, the Covered
Entities, such as tax compliance, tax planning and tax advice without impairing
the auditor's independence, and the SEC has stated that the Independent Auditors
may provide such services.

Pursuant to the preceding paragraph, the Audit Committee has pre-approved the
Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

      6. ALL OTHER SERVICES

The Audit Committee believes, based on the SEC's rules prohibiting the
Independent Auditors from providing specific non-audit services, that other
types of non-audit services are permitted. Accordingly, the Audit Committee
believes it may grant general pre-approval to those permissible non-audit
services classified as All Other services that it believes are routine and
recurring services, would not impair the independence of the auditor and are
consistent with the SEC's rules on auditor independence.

The Audit Committee has pre-approved the All Other services in Appendix B.4.
Permissible All Other services not listed in Appendix B.4 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

      7. PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS

Pre-approval fee levels or budgeted amounts for all services to be provided by
the Independent Auditors will be established annually by the Audit Committee.
Any proposed services exceeding these levels or amounts will require specific
pre-approval by the Audit Committee. The Audit Committee is mindful of the
overall relationship of fees for audit and non-audit services in determining
whether to pre-approve any such services.

      8. PROCEDURES

All requests or applications for services to be provided by the Independent
Auditors that do not require specific approval by the Audit Committee will be
submitted to the Fund's Chief Financial Officer and must include a detailed
description of the services to be

                                       5


rendered. The Fund's Chief Financial Officer will determine whether such
services are included within the list of services that have received the general
pre-approval of the Audit Committee. The Audit Committee will be informed on a
timely basis of any such services rendered by the Independent Auditors. Requests
or applications to provide services that require specific approval by the Audit
Committee will be submitted to the Audit Committee by both the Independent
Auditors and the Fund's Chief Financial Officer, and must include a joint
statement as to whether, in their view, the request or application is consistent
with the SEC's rules on auditor independence.

The Audit Committee has designated the Fund's Chief Financial Officer to monitor
the performance of all services provided by the Independent Auditors and to
determine whether such services are in compliance with this Policy. The Fund's
Chief Financial Officer will report to the Audit Committee on a periodic basis
on the results of its monitoring. Both the Fund's Chief Financial Officer and
management will immediately report to the chairman of the Audit Committee any
breach of this Policy that comes to the attention of the Fund's Chief Financial
Officer or any member of management.

      9. ADDITIONAL REQUIREMENTS

The Audit Committee has determined to take additional measures on an annual
basis to meet its responsibility to oversee the work of the Independent Auditors
and to assure the auditor's independence from the Fund, such as reviewing a
formal written statement from the Independent Auditors delineating all
relationships between the Independent Auditors and the Fund, consistent with
Independence Standards Board No. 1, and discussing with the Independent Auditors
its methods and procedures for ensuring independence.

      10. COVERED ENTITIES

Covered Entities include the Fund's investment adviser(s) and any entity
controlling, controlled by or under common control with the Fund's investment
adviser(s) that provides ongoing services to the Fund(s). Beginning with
