FUND REPORT

For the six months ended April 30, 2008

MARKET CONDITIONS

The six-month period under review was marked by disrupted credit markets,
recession fears, deterioration of the housing market, and markdowns in the
mortgage market as a result of forced selling. Although the fixed income market
saw some improvements in the last month of the period, many of the same concerns
and problems remained.

The Federal Reserve (the "Fed") stepped in several times during the period to
minimize the liquidity crisis. Not only did the Federal Open Market Committee
reduce the target federal funds rate several times, from 4.5 percent to 2.0
percent, but in an unprecedented move, the Fed granted primary Treasury dealers
(mostly brokerage firms) access to its discount window and loosened its
collateral requirements, extending loans of Treasury securities in exchange for
lower quality, less liquid securities. Finally, in what was most decidedly the
biggest headline event, the Fed arranged and supported JPMorgan Chase's purchase
of Bear Stearns, which was viewed by many as necessary to avoid serious market
repercussions had the firm failed.

The decline in short-term interest rates, coupled with the risk-averse
environment during the period pushed Treasury yields lower, especially on the
short end of the yield curve, causing the curve to steepen. The municipal yield
curve steepened as well, with the yield differential between one-year and 30-
year maturities reaching more than 300 basis points. Overall, municipal bonds
underperformed their taxable counterparts as credit rating downgrades of various
monoline bond insurers and the deterioration of the auction rate and variable
rate markets posed additional challenges for the sector. After a record year for
new municipal bond issuance in 2007, the amount of new issues coming to market
in the first four months of 2008 declined.

PERFORMANCE ANALYSIS

For the six-month period ended April 30, 2008, the net asset value (NAV) of
Morgan Stanley Insured Municipal Trust (IMT) decreased from $14.74 to $14.49 per
share. Based on this change plus reinvestment of tax-free dividends totaling
$0.33 per share and a long-term capital gain distribution of $0.019812 per
share, the Trust's total NAV return was 1.06 percent. IMT's value on the New
York Stock Exchange (NYSE) moved from $13.15 to $13.06 per share during the same
period. Based on this change plus reinvestment of dividends and distributions,
the Trust's total market return was 2.03 percent. IMT's NYSE market price was at
a 9.87 percent discount to its NAV. During the fiscal period, the Trust
purchased and retired 189,841 shares of common stock at a weighted average
market discount of 11.24 percent. Past performance is no guarantee of future
results.

Monthly dividends for the second quarter of 2008, declared in April, were
unchanged at $0.055 per share. The dividend reflects the current level of the
Trust's net investment income. IMT's level of undistributed net investment
income was $0.032 per share on April 30, 2008 versus $0.010 per share six months
earlier.(1)

Throughout the six-month period, the Trust maintained a lower interest rate
sensitivity (as measured by duration*), which was implemented through the use of
a U.S. Treasury futures hedge. This defensive positioning benefited performance
as it helped to minimize the price declines that resulted from rising

2



yields across the intermediate and long end of the municipal yield curve.

In terms of the Trust's sector positioning, an overweight in the hospital/life
care and tobacco sectors detracted from relative performance as spread widening
in those sectors hindered returns. Conversely, an overweight in the public
utility sector, particularly water and sewer bonds, benefited performance. The
flight to quality that took place during the period helped boost the performance
of the more solid infrastructure sectors such as utilities and the Trust's
holdings there enhanced returns.

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. The Trust may also utilize procedures to reduce
or eliminate the amount of Auction Rate Preferred Shares (ARPS) outstanding,
including their purchase in the open market or in privately negotiated
transactions.

the future.

(1) Income earned by certain securities in the portfolio may be subject to the
federal alternative minimum tax (AMT).

* 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. Duration calculations are adjusted for leverage.

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED)

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 taxes. 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 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; (3) interest rate
swaps are marked-to-market daily based upon quotations from market makers; (4)
investments in open-end mutual funds, including the Morgan Stanley Institutional
Liquidity Funds, are valued at the net asset value as of the close of each
business day; and (5) 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 and are included in interest income. 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

18



Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued


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 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. Floating Rate Note and Dealer Trusts Obligations Related to Securities
Held -- The Trust enters into transactions in which it transfers to Dealer
Trusts ("Dealer Trusts"), fixed rate bonds in exchange for cash and residual
interests in the Dealer Trusts' assets and cash flows, which are in the form of
inverse floating rate investments. The Dealer Trusts fund the purchases of the
fixed rate bonds by issuing floating rate notes to third parties and allowing
the Trust to retain residual interest in the bonds. The Trust enters into
shortfall agreements with the Dealer Trusts which commit the Trust to pay the
Dealer Trusts, in certain circumstances, the difference between the liquidation
value of the fixed rate bonds held by the Dealer Trusts and the liquidations
value of the floating rate notes held by third parties, as well as any
shortfalls in interest cash flows. The residual interests held by the Trust
(inverse floating rate investments) include the right of the Trust (1) to cause
the holders of the floating rate notes to tender their notes at par at the next
interest rate reset date, and (2) to transfer the municipal bond from the Dealer
Trusts to the Trust, thereby collapsing the Dealer Trusts. The Trust accounts
for the transfer of bonds to the Dealer Trusts as secured borrowings, with the
securities transferred remaining in the Trust's investment assets, and the
related floating rate notes reflected as Trust liabilities under the caption
"floating rate note and dealer trust obligations" on the Statement of Assets and
Liabilities. The Trust records the interest income from the fixed rate bonds
under the caption "Interest Income" and records the expenses related to floating
rate obligations and any administrative expenses of the Dealer Trusts under the
caption "Interest and residual trust expenses" in the Trust's statement of
Operations. The notes issued by the Dealer Trusts have interest rates that reset
weekly and the floating rate note holders have the option to tender their notes
to the Dealer Trusts for redemption at par at each reset date. At April 30,
2008, Trust investments with a value of $44,496,500 are held by the Dealer
Trusts and serve as collateral for the $33,260,000 in the floating rate note and
dealer trusts obligations outstanding at that date. Contractual maturities of
the floating rate note obligations and interest rates in effect at April 30,
2008 are presented in the Portfolio of Investments.

E. Interest Rate Swaps -- Interest rate swaps involve the exchange of
commitments to pay and receive interest based on a notional principal amount.
Net periodic interest payments to be received or paid are accrued daily and are
recorded as realized gains or losses in the Statement of


                                                                              19



Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued


Operations. The Trust may pay or receive cash to collateralize interest rate
swap contracts. This cash collateral is recorded as assets/liabilities on the
Trust's books. Any cash received may be invested in Morgan Stanley Institutional
Liquidity Funds.

F. Federal Income Tax Policy -- It is the Trust's policy to comply with the
requirements of Subchapter M of the Internal Revenue Code applicable to
regulated investment companies and to distribute substantially all of its
taxable and nontaxable income to its shareholders. Therefore, no provision for
federal income tax is required. The Trust files tax returns with the U.S.
Internal Revenue Service, New York State and New York City. The Trust adopted
the provisions of the Financial Accounting Standards Board ("FASB")
Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on
April 29, 2008. FIN 48 sets forth a minimum threshold for financial statement
recognition of the benefit of a tax position taken or expected to be taken in a
tax return. The implementation of FIN 48 did not result in any unrecognized tax
benefits in the accompanying financial statements. If applicable, the Trust
recognizes interest accrued related to unrecognized tax benefits in interest
expense and penalties in other expenses in the Statement of Operations. Each of
the tax years in the four year period ended April 30, 2008, remains subject to
examination by taxing authorities.

G. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

H. 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 Advisory/Administration Agreements
Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment
Advisors Inc. (the "Investment Adviser"), the Trust pays the Investment Adviser
an advisory fee, calculated weekly and payable monthly, by applying the annual
rate of 0.27% to the Trust's average weekly net assets including preferred
shares.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Trust
pays an administration fee, calculated weekly and payable monthly, by applying
the annual rate of 0.08% to the Trust's average weekly net assets including
preferred shares.

Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued

Under an agreement between the Administrator and State Street Bank and Trust
Company ("State Street"), State Street provides certain administrative services
to the Trust. For such services, the Administrator pays State Street a portion
of the fee the Administrator receives from the Trust.

3. Security Transactions and Transactions with Affiliates
The Trust invests in Morgan Stanley Institutional Liquidity Tax-Exempt
Portfolio -- Institutional Class, an open-end management investment company
managed by the Investment Adviser. Investment advisory fees paid by the Trust
are reduced by an amount equal to the advisory and administrative service fees
paid by Morgan Stanley Institutional Liquidity Tax-Exempt
Portfolio -- Institutional Class with respect to assets invested by the Trust in
Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio  -- Institutional
Class. For the six months ended April 30, 2008, advisory fees paid were reduced
by $5,960 relating to the Trust's investment in Morgan Stanley Institutional
Liquidity Tax-Exempt Portfolio -- Institutional Class. Income distributions
earned by the Trust are recorded as dividends from affiliate in the Statement of
Operations and totaled $130,310 for the six months ended April 30, 2008. During
the six months ended April 30, 2008, cost of purchases and sales of investments
in Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -- Institutional
Class aggregated $46,176,889 and $39,577,461, respectively.

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended April 30, 2008, aggregated
$36,021,143 and $41,483,361, respectively.

The Trust has an unfunded noncontributory defined benefit pension plan covering
certain 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 factors which include years of service and compensation. The
Trustees voted to close the plan to new participants and eliminate the future
benefits growth due to increases to compensation after July 31, 2003. Aggregate
pension costs for the six months ended April 30, 2008, included in Trustees'
fees and expenses in the Statement of Operations amounted to $2,541. At April
30, 2008, the Trust had an accrued pension liability of $55,456 which is
included in accrued expenses in the Statement of Assets and Liabilities.

The Trust has 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 or she 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.

NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued


distributions received from these investments are recorded with an 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 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 six months ended April 30, 2008.

Subsequent to April 30, 2008 and up through June 6, 2008, the Trust paid
dividends to Series TU and TH at rates ranging from 2.37% to 2.90%, in the
aggregate amount of $369,718.

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.

  $0.055     June 20 2008    June 27, 2008



7. Expense Offset
The expense offset represents a reduction of the fees and expenses for interest
earned on cash balances maintained by the Trust with the transfer agent and
custodian.

8. Purposes of and Risks Relating to Certain Financial Instruments
The Trust may invest a portion of its assets in inverse floating rate
instruments, either through outright purchases of inverse floating rate
securities or through the transfer of bonds to a Dealer Trusts in exchange for
cash and residual interests in the Dealer Trusts (See Note 1D). These
investments are typically used by the Trust in seeking to enhance the yield of
the portfolio. These instruments typically involve greater risks than a fixed
rate municipal bond. In particular, these instruments are acquired through
leverage or may have leverage embedded in them and therefore involve many of the
risks associated with leverage. Leverage is a speculative technique that may
expose the Trust to greater risk and increased costs. Leverage may cause the
Trust's net asset value to be more volatile than if it had not been leveraged
because leverage tends to magnify the effect of any increases or decreases in
the value of the Trust's portfolio securities. The use of leverage may


                                                                              23



Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued

also cause the Trust to liquidate portfolio positions when it may not be
advantageous to do so in order to satisfy its obligations with respect to
inverse floating rate instruments.

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.

The Trust may enter into interest rate swaps and may purchase or sell interest
rate caps, floors and collars. The Trust expects to enter into these
transactions primarily to manage interest rate risk, hedge portfolio positions
and preserve a return or spread on a particular investment or portion of its
portfolio. The Trust may also enter into these transactions to protect against
any increase in the price of securities the Trust anticipates purchasing at a
later date. Interest rate swap transactions are subject to market risk, risk of
default by the other party to the transaction, risk of imperfect correlation and
manager risk. Such risks may exceed the related amounts shown in the Statements
of Assets and Liabilities.

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.

As of October 31, 2007, 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.

10. Accounting Pronouncements
On March 19, 2008, FASB released Statement of Financial Accounting Standards No.
161, "Disclosures about Derivative Instruments and Hedging Activities" ("FAS
161"). FAS 161 requires qualitative disclosures about objectives and strategies
for using derivatives, quantitative disclosures about fair value amounts of and
gains and losses on derivative instruments, and disclosures about

24



Morgan Stanley Insured Municipal Trust
NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued

credit- risk-related contingent features in derivative agreements. The
application of FAS 161 is required for fiscal years beginning after November 15,
2008 and interim periods within those fiscal years. At this time, management is
evaluating the implications of FAS 161 and its impact on the financial
statements has not yet been determined.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of SFAS
157 will have on the Trust's financial statement disclosures.



                                                                              25

Morgan Stanley Insured Municipal Trust
REVISED INVESTMENT POLICY (UNAUDITED)


While the Trust's policy is to emphasize investments in municipal obligations
with longer-term maturities because generally longer-term obligations, while
more susceptible to market fluctuations resulting from changes in interest
rates, produce higher yields than short-term obligations, the Trust no longer
expects to maintain a specific average weighted maturity of its portfolio. As a
result of changes in the fixed-income and municipal marketplace, the Trust's
average portfolio maturity will vary depending upon market conditions and other
factors.



                                                                              27
