LETTER TO THE SHAREHOLDERS April 30, 1998
 
DEAR SHAREHOLDER:
 
We are pleased to present the semiannual report on the operations of
InterCapital Insured Municipal Trust (IMT) for the period ended April 30, 1998.
 
Since last fall domestic economic growth has been tempered by the deflationary
impact of the Asian financial crisis. U.S. employment conditions strengthened
and the unemployment rate declined to its lowest level since 1970. Inflation
remained subdued despite the robust economy. In part this was the result of
productivity gains and the lower costs of oil and other imports. Foreign
currency turmoil strengthened the value of the U.S. dollar and created demand
for U.S. Treasury securities. Municipal bonds followed the trend of Treasuries
and yields declined to levels last seen 20 years ago. The bond market rally was
also aided by prospects of the first federal budget surplus in more than two
decades.
 
MUNICIPAL MARKET CONDITIONS
 
Long-term insured index yields ended April 1998 at 5.35 percent after reaching a
low of 5.15 percent in December and January. Over the past

12 months the insured index yield has declined from 5.75 percent. The yield on
one-year notes was 3.75 percent at the end of April 1998. Thus, the yield pickup
for extending maturities from 1 to 30 years was 160 basis points.
 
The overall decline in interest rates led to an increase in new-issue municipal
volume. In contrast, the federal deficit has shrunk and the U.S. Treasury's
borrowing needs have declined. Under these conditions, the municipal rally
lagged the rally in Treasuries. The ratio of municipal yields to Treasury yields
improved from 87 percent in October to almost 90 percent in April. A year ago
the ratio was a relatively rich 83 percent. A rising ratio means that municipals
have underperformed Treasuries but have become relatively more attractive.
 
Total municipal volume increased 20 percent in 1997. New-issue supply totaled
$220 billion last year, with half the underwritings enhanced with bond
insurance. Overall, refundings represented one-quarter of total new issues. For
the year-to-date, municipal underwriting is up 60 percent with refunding issues
comprising one-third of the total.
 
PERFORMANCE
 
During the six-month period ended April 30, 1998, the Trust's net asset value
(NAV) declined from $15.96 to $15.84. Based on this NAV change plus reinvestment
of tax-free dividends totaling $0.48 per share, the Trust's total NAV return was
2.29 percent. IMT's price on the New York Stock Exchange increased from $15.25
to $15.3125 per share. Based on this change in market price plus reinvestment of
dividends, the Trust's total market return was 3.49 percent. On April 30, 1998,
IMT was trading at a 3.33 percent discount to NAV. This means that the market
price of the common stock was lower than the NAV.
 
Monthly dividends payable in the second quarter of 1998 were declared in March
and remained unchanged at $0.08 per share. The level of undistributed net
investment income increased from $0.062 to $0.065 per share over the past six
months.
 
The Trust's procedure for reinvestment of all dividends and distributions on
common shares is through purchases in the open market. This method helps to
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 outstanding Auction Rate Preferred Shares (ARPS),
including their purchase in the open market or in privately negotiated
transactions.

PORTFOLIO STRUCTURE
 
The Trust remained fully invested in long-term municipal bonds during the
period. Investments were diversified among 12 long-term sectors and 52 credits.
As illustrated in the accompanying chart, refunded bonds to be called within 10
years comprised 38 percent of net assets. The Trust's weighted average maturity
was 16 years. The distribution of call dates in the portfolio produced 4 years
of weighted average call protection. To assure timely payment of principal and
interest, each position in the portfolio was backed by triple "A" rated bond
insurance.
 
THE IMPACT OF LEVERAGING
 
As discussed in previous reports, the total income available for distribution to
common shareholders includes incremental income provided by the Trust's
outstanding Auction Rate Preferred Shares (ARPS). ARPS dividends reflect
prevailing short-term interest rates on maturities normally ranging from one
week to one year. Incremental income to common shareholders depends on two
factors. The first is the amount of ARPS outstanding, the second the spread
between the portfolio's cost yield and 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 common
shareholders. The level of net investment income available for distribution to
common shareholders varies with the level of short-term interest rates.
 
During the six-month period, ARPS leverage contributed approximately $0.07 per
share to common share earnings. Weekly ARPS yields ranged between 3.19 and 4.20
percent. IMT's two ARPS series totaled $130 million and represented 27 percent
of net assets.
 
LOOKING AHEAD
 
The economic fundamentals are in place for another year of solid, albeit less
spectacular, domestic growth in 1998. Events in Asia have strengthened the U.S.
dollar and contributed to lower interest rates. The Asian financial crisis seems
likely to moderate U.S. economic growth and inflationary pressures. While this
outlook is favorable for municipal bonds it is possible that the Federal Reserve
Board may begin to tighten monetary policy if capacity and labor constraints
cause cost pressures to mount.

INTERCAPITAL INSURED MUNICIPAL TRUST
 
NOTES TO FINANCIAL STATEMENTS April 30, 1998 (unaudited)
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
InterCapital 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 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.
 
The following is a summary of significant accounting policies.
 
A. VALUATION OF INVESTMENTS -- Portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service has
informed the Trust that in valuing the portfolio securities, it uses both a
computerized 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. 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.
The Trust amortizes premiums and accretes discounts over the life of the
respective securities. Interest income is accrued daily.
 
C. FEDERAL INCOME TAX STATUS -- It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Trust records dividends
and distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net

INTERCAPITAL INSURED MUNICIPAL TRUST
 
NOTES TO FINANCIAL STATEMENTS April 30, 1998 (unaudited) continued
 
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 financial reporting purposes but not for tax
purposes are reported as dividends in excess of net investment income or
distributions in excess of net realized capital gains. To the extent they exceed
net investment income and net realized capital gains for tax purposes, they are
reported as distributions of paid-in-capital.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, 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.
 
Under the terms of the Agreement, the Investment Manager maintains certain of
the Trust's books and records and furnishes, at its own expense, office space,
facilities, equipment, clerical, bookkeeping and certain legal services and pays
the salaries of all personnel, including officers of the Trust who are employees
of the Investment Manager. The Investment Manager also bears the cost of
telephone services, heat, light, power and other utilities provided to the
Trust.
 
3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended April 30, 1998 aggregated
$2,866,650 and $2,375,000, respectively.
 
Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager, is
the Trust's transfer agent.

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.

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.
