FUND REPORT

For the year ended October 31, 2003

MARKET CONDITIONS


Over the past 12 months the tone of the U. S. economy shifted from weak to
accelerating growth culminating in 8.2 percent GDP growth in the third quarter
of 2003. One of the most closely watched economic indicators, employment
strength, was in negative territory for much of the period. Repeated comments
from government and private sector economists suggesting that the U.S. economy
might be entering a deflationary period also weighed heavily on investors during
much of the year. At the same time, ongoing budgetary and fiscal difficulties at
the state and local levels contributed to ratings downgrades for many municipal
bonds. The Federal Reserve Board attempted to allay these fears and keep the
economy moving forward by cutting the federal funds target rate twice to a level
of 1.0 percent.

The uncertain economic climate had an effect on the municipal bond market. While
yields on intermediate and long-term bonds ended the period roughly where they
began, the road between those two points was decidedly bumpy. The 12-month
period can be divided into two distinct market environments. The first, which
lasted from October 2002 to mid-June 2003, saw municipal yields fall by roughly
75 basis points to levels not seen since the late 1960s. Plummeting yields led
to a surge in issuance as municipalities moved to lock in new low financing
rates and, in the case of older bonds, low refinancing costs. Record levels of
supply met with strong demand by investors in search of tax-exempt income to
offset low money
market rates. Also, the relatively attractive yield of municipal bonds versus
Treasuries created demand from institutional taxable investors who
"crossed-over" to purchase municipals.

The municipal market reversed abruptly in mid-June, when yields began to climb
from their lows and investors shifted their attention to the improving equity
market. Participation from cross-over investors also evaporated as taxable
yields rose faster than those of tax-exempts. Issuance remained strong through
July, but declined over the last three months as yields rose. These forces
combined to push municipal-bond yields above their historic lows, ending the
fiscal year near where they began.

PERFORMANCE ANALYSIS


The net asset value (NAV) of Morgan Stanley Insured Municipal Trust (IMT)
decreased from $15.50 to $15.38 per share for the fiscal year ended October 31,
2003. Based on this change plus reinvestment of tax-free dividends totaling
$0.898 per share, a short-term capital gain distribution of $.003 per share and
a long-term capital gain distribution of $.224 per share, the Trust's total NAV
return was 7.19 percent. IMT's value on the New York Stock Exchange (NYSE)
increased from $14.15 to $14.38 per share during the same period. Based on this
change plus reinvestment of tax-free dividends, the Trust's total market return
was 9.78 percent. On October 31, 2003, IMT's NYSE market price was at a 6.50
percent discount to its NAV. Past performance is no guarantee of future results.

Monthly dividends for the fourth quarter of 2003 were declared in September.
Beginning with the October payment the monthly payment decreased from $0.075 to
$0.0725 per share. The new dividend reflects the level of the Trust's
undistributed net investment income and projected earnings power. The Trust's
level of undistributed net investment income was $0.083 per share on October 31,
2003 versus $0.144 per share as of October 31, 2002. Past performance is no
guarantee of future results.

From a strategic point of view, with interest rates at multi-decade lows, we
also became increasingly concerned that the next significant shift in interest
rates would be upward. As a result, we began to establish a hedge position by
selling Treasury futures to reduce the portfolio's duration (a measure of
interest rate sensitivity). This allowed us to maintain an average maturity
target range of 20 years in order to take advantage of the steepness of the
municipal yield curve. Nevertheless, market yields on new investments were lower
than the book yields on portfolio holdings called for redemption. The
portfolio's duration adjusted for leverage was 11.4 years. We continued to
emphasize revenue bonds in sectors tied to reliable income streams from
essential services such as municipal electric, transportation and water and
sewer. As of October 31, 2003, the Trust's net assets, including preferred
shares, of $439 million were diversified across 66 credits in 13 long-term
sectors.

As discussed in previous reports, the total income available for distribution to
holders of common shares includes incremental income provided by the Trust's
outstanding Auction Rate Preferred Shares (ARPS). ARPS dividends reflect
prevailing interest rates on maturities normally ranging from one week to two
years. Incremental income to holders of common shares depends on two factors.
The first is the amount of ARPS outstanding, the second the spread between the
portfolio's cost yield and its ARPS expenses (ARPS auction rate and expenses).
The greater the spread and the amount of ARPS outstanding, the greater the
amount of incremental income available for distribution to holders of common
shares. The level of net investment income available for distribution varies
with the level of short-term interest rates. ARPS leverage also increases the
price volatility of common shares and has the effect of extending portfolio
duration.

During the 12-month period, ARPS leverage contributed approximately $0.16 per
share to common share earnings. The Trust has two ARPS series totaling $130
million and representing 30 percent of net assets including preferred shares.
Both series are two-year auctions maturing in January 2004 and January 2005
yielding 2.55 and 1.449 percent, respectively.

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

                                                                               3


market value or net asset value, whichever is lower at the time of purchase. The
Trust may also utilize procedures to reduce or eliminate the amount of
outstanding ARPS, including their purchase in the open market or in privately
negotiated transactions. During the 12-month period ended October 31, 2003, the
Trust purchased and retired 558,000 shares of common stock at a weighted average
market discount of 6.008 percent.

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2003

1. Organization and Accounting Policies

Morgan Stanley Insured Municipal Trust (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 federal income tax. The Trust was organized
as a Massachusetts business trust on October 3, 1991 and commenced operations on
February 28, 1992.

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 bid side of the market each day. 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; (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 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

16


Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2003 continued

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 a management fee,
calculated weekly and payable monthly, by applying the annual rate of 0.35% to
the Trust's weekly net assets including preferred shares.

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, 2003 aggregated
$52,692,455 and $47,233,734, respectively. Included in the aforementioned are
purchases and sales of $9,674,184 and $9,262,885, respectively with other Morgan
Stanley funds including a net realized loss of $315,553.

Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's
transfer agent. At October 31, 2003, the Trust had transfer agent fees and
expenses payable of approximately $12,600.

The Trust has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Trust who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended October 31, 2003 included
in Trustees' fees and expenses in the Statement of Operations amounted to
$6,570. At October 31, 2003, the Trust had an accrued pension liability of
$52,587 which is included in accrued expenses in the Statement of Assets and
Liabilities.

                                                                              17

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 Trust has issued Series TU and TH Auction Rate
Preferred Shares ("Preferred Shares") which 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.

Dividends, which are cumulative, are reset through auction procedures.

   ** For the year ended October 31, 2003.

Subsequent to October 31, 2003 and up through December 5, 2003 the Trust paid
dividends to Series TU and TH at rates ranging from 2.55% to 1.449% in the
aggregate amount of $387,368.

The Trust is 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, which are 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.

investment income:

 $0.0725   December 5, 2003   December 19, 2003
</Table>

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.

At October 31, 2003, the Trust held positions in residual interest bonds having
a total value of $12,119,029, which represents 3.9% of the Trust's net assets
applicable to common shareholders.

To hedge against adverse interest rate changes, the Trust may invest in
financial futures contracts or municipal bond index futures contracts ("futures
contracts").

                                                                              19


Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2003 continued

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.

At October 31, 2003, the Trust had outstanding futures 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.

The tax character of distributions paid was as follows:

</Table>

As of October 31, 2003, the Trust had temporary book/tax differences primarily
attributable to book amortization of premiums on debt securities, mark-to-market
of open futures contracts and dividend payable 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 realized gain was charged and accumulated
undistributed net investment income was credited $21,179.

INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Trustees of
Morgan Stanley Insured Municipal Trust:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Insured Municipal Trust (the "Trust"), including the portfolio of
investments, as of October 31, 2003, 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 auditing standards generally accepted
in the United States of America. 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, 2003, by correspondence with the custodian
and brokers. 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 Municipal Trust as of October 31, 2003, 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

principles generally accepted in the United States of America.

Item 2.  Code of Ethics.

(a)      The Trust has adopted a code of ethics (the "Code of Ethics") that
applies to its principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar
functions, regardless of whether these individuals are employed by the Trust or
a third party.

(b)      No information need be disclosed pursuant to this paragraph.

(c)      Not applicable.

(d)      Not applicable.

(e)      Not applicable.

(f)

         (1)      The Trust's Code of Ethics is attached hereto as Exhibit A.

         (2)      Not applicable.

         (3)      Not applicable.



Item 3.  Audit Committee Financial Expert.

The Trust's Board of Trustees has determined that it has two "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Trustees: Dr. Manuel H. Johnson and Joseph J. Kearns. Under
applicable securities laws, a person who is determined to be an audit committee
financial expert will not be deemed an "expert" for any purpose, including
without limitation for the purposes of Section 11 of the Securities Act of 1933,
as a result of being designated or identified as an audit committee financial
expert. The designation or identification of a person as an audit committee
financial expert does not impose on such person any duties, obligations, or
liabilities that are greater than the duties, obligations, and liabilities
imposed on such person as a member of the audit committee and Board of Trustees
in the absence of such designation or identification.



Item 4. Principal Accountant Fees and Services

Applicable only for reports covering fiscal years ending on or after December
15, 2003.






Item 5. Audit Committee of Listed Registrants.

Applicable only for reports covering periods ending on or after the earlier of
(i) the first annual shareholder meeting after January 15, 2004 or (ii) October
31, 2004.


Item 6. [Reserved.]


Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End
Management Investment Companies.

The Trust invests in exclusively non-voting securities and therefore this item
is not applicable.


Item 8. [Reserved.]


Item 9 - Controls and Procedures

(a) The Trust's principal executive officer and principal financial officer have
concluded that the Trust's disclosure controls and procedures are sufficient to
ensure that information required to be disclosed by the Trust in this Form N-CSR
was recorded, processed, summarized and reported within the time periods
specified in the Securities and Exchange Commission's rules and forms, based
upon such officers' evaluation of these controls and procedures as of a date
within 90 days of the filing date of the report.

        There were no significant changes or corrective actions with regard to
significant deficiencies or material weaknesses in the Trust's internal controls
or in other factors that could significantly affect the Trust's internal
controls subsequent to the date of their evaluation.


(b) There were no changes in the registrant's internal control over financial
reporting that occurred during the registrant's most recent fiscal half-year
(the registrant's second fiscal half-year in the case of an annual report) that
has materially affected, or is reasonably likely to materially affect, the
registrant's internal control over financial reporting.
