DEAR SHAREHOLDER

For the six months ended February 28, 2001, Merrill Lynch High Income Municipal
Bond Fund, Inc. earned $0.265 per share income dividends, representing a net
annualized yield of 5.76%, based on a month-end per share net asset value of
$9.26. Over the same period, the Fund's total investment return was +0.81%,
based on a change in per share net asset value from $9.45 to $9.26, and assuming
reinvestment of $0.266 per share income dividends.

The Municipal Market Environment During the six months ended February 28, 2001,
long-term fixed- income bond yields generally declined. The strength seen in the
US




economy in 1999 and early 2000 clearly has moderated in recent months. After
growing approximately 5% in the first half of 2000, US gross domestic product
(GDP) declined to 2.2% during the third quarter of 2000. An estimate of fourth
quarter 2000 GDP growth was recently released at 1.1%. Additionally, over the
past six months, inflationary pressures have remained well contained, largely in
the 2% - 3% range. As a result of moderating economic growth and low inflation,
US Treasury bond yields remained relatively stable into late October 2000.

However, rising oil and natural gas prices rekindled investors' inflationary
fears and US Treasury bond yields quickly rose to nearly 6% by early November
2000. During late November and early December, long-term bond yields fluctuated
in response to declining commodity prices and the considerable uncertainty
surrounding the presidential election. In December 2000, significant declines in
US equity markets, especially the NASDAQ, as well as another series of weak
economic indicators, combined to reestablish the decline in long-term US
Treasury bond yields. By mid-December, the Federal Reserve Board announced that
current economic conditions warranted the cessation of the series of short-term
interest rate increases they had initiated in February 2000. Given the favorable
economic environment and, at least, a neutral Federal Reserve Board policy,
investors were free again to focus on the ongoing US Treasury debt reduction
program and forecasts of sizeable Federal budgetary surpluses going forward.
Many analysts and investors concluded that there would be a significant future
shortage of longer-maturing US Treasury securities. These factors helped push US
Treasury bond yields lower. By the end of December, US Treasury bond yields
declined to 5.45%, their lowest monthly closing level in almost two years.

In early January 2001, the Federal Reserve Board lowered short-term interest
rates by 50 basis points (0.50%), citing declining consumer confidence and
weakening industrial production and retail sales growth. Similar reasons were
given for an additional 50 basis point reduction in short-term interest rates by
the Federal Reserve Board at the end of January 2001. However, despite recent
reductions in short-term interest rates, US equity markets remained weak. This
has led many investors to seek the safety of fixed-income markets, causing bond
yields to decline further. By the end of the six-month period ended February 28,
2001, US Treasury bonds declined overall by nearly 30 basis points to close the
period at 5.30%.

Long-term tax-exempt bonds also responded well to the economic environment that
developed during the last six months. While municipal bond yields followed a
downward pattern similar to that of US Treasury bonds, tax-exempt bond price
volatility was limited. Municipal bond yields traded in a relatively narrow
range, generally declining steadily throughout the last six months. Overall
investor demand for municipal bonds has remained very positive, allowing tax-
exempt bond yields, as measured by the Bond Buyer Revenue Bond Index, to decline
25 basis points to end the period at 5.47%, their lowest monthly closing level
in more than 18 months.

Merrill Lynch High Income Municipal Bond Fund, Inc.
February 28, 2001

The underperformance of the municipal bond market mainly reflected the dramatic
increase in tax-exempt bond issuance over the past few months. The decline in
tax-exempt bond yields triggered a large number of municipalities to refinance
outstanding higher-couponed issues as well as issue new debt to support capital
projects such as school buildings and general infrastructure needs. During the
past 12 months, more than $211 billion in new long-term municipal


                                  2


securities was issued, an increase of almost 5% compared to the same 12-month
period a year ago. During the last six months, nearly $110 billion in new
tax-exempt bonds was underwritten, an increase of over 12% when compared to the
same six-month period a year ago. More than $55 billion in new long-term
municipal bonds was financed during the past three months, a staggering increase
of over 40% compared to the same three-month period a year ago. This dramatic
response to falling tax-exempt bond yields by municipalities can be seen in the
monthly issuance for February 2001 as over $20 billion in new long-term
municipal bonds was underwritten, an increase of more than 60% compared to
monthly issuance in February 2000.

The recent increase in tax-exempt bond issuance prevented municipal bond yields
from declining as much as US Treasury bond yields. Overall investor demand for
municipal bonds remained strong and came from a number of non-traditional and
conventional sources. Derivative/arbitrage programs and insurance companies
remained the dominant buyers, while individual retail investor demand also
remained strong. Tax-exempt bond funds experienced renewed investor interest.
Rising equity market valuations throughout most of last year siphoned away much
of the demand from municipal bond mutual funds. In January 2000, tax-exempt
mutual bond funds experienced net cash outflows of more than $4 billion as
investors withdrew from bond funds mainly to finance the purchase of various
equity securities. The increased demand for tax-exempt issues to a great extent
resulted from the continued decline of US equity markets, but even more, from
the attractive tax-exempt bond yield ratios currently available. Many investors
fled the instability and uncertainty of the equity market for the safety and
security of municipal bond issues yielding 90% - 95% of comparable US Treasury
bond yields.

The outlook for the tax-exempt bond market in 2001 appears quite favorable. The
steeply positive yield curve and relatively high credit quality that the
municipal bond market offers should continue to attract retail and institutional
investors seeking both tax- exempt income and a ready substitute for relatively
scarce US Government securities. Strong state and local governmental financial
conditions also suggest that issuance should remain manageable in the coming
months. Research analysts suggest that annual issuance in 2001 is likely to
remain in the $200 billion range. Additionally, while it appears likely that
President Bush will keep his campaign promise to lower Federal income tax rates
in 2001, any legislation is unlikely to be enacted before late summer. These
factors suggest that the strong technical position the municipal bond market has
enjoyed is likely to continue. Given recent market performance, the strong
returns illustrate the excellent investment diversification municipal bonds can
provide to investors.

Portfolio Strategy
In contrast to the six-month period ended August 31, 2000, in which the
high-yield tax-exempt market deteriorated significantly, the six- month period
ended February 28, 2001 saw a marked improvement in valuations for much of the
high-yield sector. The more constructive environment was attributable to the
abrupt and forceful shift in monetary policy by the Federal Reserve Board in
January 2001 brought on by the rapid deterioration in economic fundamentals.
Encouraged by prospects of steadily declining short-term interest rates, fixed-
income investors increased exposure to speculative-grade credits in anticipation
of the stimulative effect of an easier monetary policy. Implicit in the decision
to reallocate asset weightings in this manner was the belief that credit spreads
already reflected current weak economic conditions. The anticipatory nature of
markets suggests that investors are looking beyond present circumstances and are
beginning to discount an eventual economic rebound. In effect, investors are
confident that the Federal Reserve Board will be


                                  3


successful in its efforts to reignite growth.

While these developments indicate that a brighter outlook lies ahead, the months
leading up to the Federal Reserve Board's first interest rate reduction proved
to be a difficult environment for investors in the high-yield market. Poor
liquidity and an anemic investor demand continued to chip away at valuations.
The effect was even more pronounced as the late year bond market rally was
largely confined to the higher investment-grade sectors. By year end, with
investor sentiment at its lowest point and credit spreads near their widest
point in several years, the stage was set for the Federal Reserve Board's
monetary policy easing and the ensuing turnaround.

Our investment strategy for the Fund remains largely unchanged as we
consistently seek to manage reinvestment risk in an effort to stablilize the
Fund's dividend income in a variety of interest rate environments. The
distressed nature of the high-yield market provided us with the opportunity to
continue the gradual restructuring of the Fund at some of the most attractive
yields in recent years. Examples of recent additions to the Fund include
investments in long-term care providers in New Jersey, Wisconsin and North
Carolina. Favorable demographic trends and strong management track records
suggest that the historically low valuations currently in this sector may not
last long. Despite the well-publicized financial woes affecting California's two
largest privately owned utilities, the utility sector remains a favorite given
current trends toward consolidation within the industry. The Fund had no
exposure to either utility and was unaffected by the subsequent decline in
market value of their respective debt obligations.

In Conclusion

We appreciate your ongoing interest in Merrill Lynch High Income Municipal Bond
Fund, Inc., and we look forward to assisting you with your financial needs in
the months and years ahead.

ABOUT INVERSE FLOATERS

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, interest rates on inverse
floaters will decrease when short- term interest rates increase and increase
when short-term interest rates decrease. Investments in inverse floaters may be
characterized as derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested principal. In
addition, inverse floaters have the effect of providing investment leverage and,
as a result, the market value of such securities will generally be more volatile
than that of fixed rate, tax-exempt securities. To the extent the Fund invests
in inverse securities, the market value of the Fund's portfolio and the net
asset value of the Fund's shares may also be more volatile than if the Fund did
not invest in such securities.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:


                                  11


Merrill Lynch High Income Municipal Bond Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a continuously offered,
non-diversified, closed-end management investment company. The Fund's financial
statements are prepared in conformity with accounting principles generally
accepted in the United States of America, which may require the use of
management accruals and estimates. These unaudited financial statements reflect
all adjustments, which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal, recurring nature. 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. Options written or
purchased are valued at the last sale price in the case of exchange-traded
options. In the case of options traded in the over- the-counter market,
valuation is the last asked price (options written) or the last bid price
(options purchased). Short-term investments with remaining maturities of sixty
days or less are valued at amortized cost, 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 Directors of the Fund, including valuations furnished by a pricing
service retained by the Fund, which may utilize a matrix system for valuations.
The procedures of the pricing service and its valuations are reviewed by the
officers of the Fund under the general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various portfolio
investment strategies to increase or decrease the level of risk to which the
Fund is exposed more quickly and efficiently than transactions in other types of
instruments. Losses may arise due to changes in the value of the contract or if
the counterparty does not perform under the contract.

* 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.

* Options--The Fund is authorized to write covered call options and purchase put
and call options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the option written. When a security is purchased or sold through
an exercise of an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from (or added to)
the proceeds of the security sold. When


                                  12


an option expires (or the Fund enters into a closing transaction),
the Fund realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the closing
transaction exceeds the premium paid or received). Written and purchased options
are non-income producing investments. (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.

NOTES TO FINANCIAL STATEMENTS (continued)

(d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Interest income is recognized on the accrual basis. The
Fund will adopt the provisions to amortize all premiums and discounts on debt
securities effective September 1, 2001, as now required under the new AICPA
Audit and Accounting Guide for Investment Companies. The cumulative effect of
this accounting change will have no impact on the total net assets of the Fund.
The impact of this accounting change has not been determined, but will result in
an adjustment to the cost of securities and a corresponding adjustment to net
unrealized appreciation/depreciation, based on securities held as of August 31,
