Annual Report

October 31, 2000


MuniYield Michigan Insured Fund, Inc. seeks to provide shareholders
with as high a level of current income exempt from Federal and
Michigan income taxes as is consistent with its investment policies
and prudent investment management by investing primarily in a
portfolio of long-term municipal obligations the interest on which,
in the opinion of bond counsel to the issuer, is exempt from Federal
and Michigan income taxes.

This report, including the financial information herein, is
transmitted to the shareholders of MuniYield Michigan Insured Fund,
Inc. for their information. It is not a prospectus. Past performance
results shown in this report should not be considered a
representation of future performance. The Fund has leveraged its
Common Stock by issuing Preferred Stock to provide the Common Stock
shareholders with a potentially higher rate of return. Leverage
creates risks for Common Stock shareholders, including the
likelihood of greater volatility of net asset value and market price
of the Common Stock, and the risk that fluctuations in the short-
term dividend rates of the Preferred Stock may affect the yield to
Common Stock shareholders. Statements and other information herein
are as dated and are subject to change.

The Benefits and
Risks of
Leveraging

MuniYield Michigan Insured Fund, Inc. utilizes leveraging to seek to
enhance the yield and net asset value of its Common Stock. However,
these objectives cannot be achieved in all interest rate
environments. To leverage, the Fund issues Preferred Stock, which
pays dividends at prevailing short-term interest rates and invests
the proceeds in long-term municipal bonds. The interest earned on
these investments is paid to Common Stock shareholders in the form
of dividends, and the value of these portfolio holdings is reflected
in the per share net asset value of the Fund's Common Stock.
However, in order to benefit Common Stock shareholders, the yield
curve must be positively sloped; that is, short-term interest rates
must be lower than long-term interest rates. At the same time, a
period of generally declining interest rates will benefit Common
Stock shareholders. If either of these conditions change, then the
risks of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred Stock
for an additional $50 million, creating a total value of $150
million available for investment in long-term municipal bonds. If
prevailing short-term interest rates are approximately 3% and long-
term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

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, income 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 floaters, 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.

DEAR SHAREHOLDER

For the year ended October 31, 2000, the Common Stock of MuniYield
Michigan Insured Fund, Inc. earned $0.790 per share income
dividends, which included earned and unpaid dividends of $0.065.
This represents a net annualized yield of 5.45%, based on a month-
end net asset value of $14.48 per share. Over the same period, the
total investment return on the Fund's Common Stock was +11.19%,
based on a change in per share net asset value from $13.91 to
$14.48, and assuming reinvestment of $0.795 per share income
dividends.

For the six-month period ended October 31, 2000, the total
investment return on the Fund's Common Stock was +7.69%, based on a
change in per share net asset value from $13.89 to $14.48, and
assuming reinvestment of $0.391 per share income dividends.

For the six-month period ended October 31, 2000, the Fund's Auction
Market Preferred Stock had an average yield of 4.30% for Series A,
3.95% for Series B and 4.25% for Series C.


The Municipal Market Environment
During the six months ended October 31, 2000, long-term US Treasury
bond yields generally drifted lower. A number of economic
indicators, particularly employment, new home sales and consumer
spending, have suggested that US economic growth, while still
strong, has moderated from 1999's robust levels. Preliminary
estimates for third-quarter 2000 US gross domestic product growth
were recently released at 2.7%, well below the first-quarter 2000
rate of 4.8% and the second-quarter 2000 rate of 5.6%. This decline
in economic growth suggests to some analysts that the Federal
Reserve Board has finished raising interest rates for its current
interest rate cycle. The Federal Reserve Board increased short-term
interest rates at its May meeting and has since kept monetary policy
steady at its subsequent meetings. Given the potential for stable
short-term interest rates in the coming months, investor emphasis
focused on the continuing US Treasury debt reduction program and
forecasts of sizeable Federal budgetary surpluses going forward.
Many investors have concluded that there will be a significant
future shortage of longer-dated maturity US Treasury securities. By
late August, US Treasury bond yields declined 30 basis points
(0.30%) to 5.66%, their lowest level in more than a year.

However, for the remainder of the period, bond yields were unable to
maintain their earlier gains. Rising oil prices were the major focus
behind the decline in bond prices, as many investors feared that
higher oil prices would result in increased inflationary pressures.
Additionally, US corporations issued large amounts of taxable debt
in order to take advantage of the current low interest rate
environment. During the last three months, US corporations issued
more than $100 billion in investment-grade securities, offering
yields in the 7.25%--9% range. Many investors found these taxable
issues an attractive and more plentiful alternative to US Treasury
bonds. As the demand for US Treasury issues weakened, US bond yields
rose. Although US Treasury bond yields rose 5.78% by the end of
October 2000, overall they declined almost 20 basis points during
the last six months.

The six-month period ended October 31, 2000 was one of the few
periods in recent years in which the tax-exempt bond market
outperformed its taxable counterpart, the US Treasury bond market.
While municipal bond yields followed the similar seesaw pattern of
Treasury bond yields, tax-exempt bond price volatility was
significantly reduced. Municipal bond yields traded in a relatively
narrow range during much of October 2000. Overall investor demand
for municipal bonds remained strong, allowing tax-exempt bond
yields, as measured by the Bond Buyer Revenue Bond Index, to decline
30 basis points to end the period at 5.75%.

In the past three months, new long-term municipal bond issuance has
continued to decline, albeit at a slower rate than earlier this
year. Over this period, more than $53 billion in new long-term
municipal bonds was issued, a decline of 3% compared to the same
three-month period in 1999. During the last six months, more than
$105 billion in tax-exempt bonds was underwritten, a decline of 8%
compared to the same six-month period in 1999. Just under $200
billion in new municipal securities was marketed during the past
year, a decline of more than 16% compared to the same 12-month
period in 1999.

The demand for municipal bonds came from a number of non-traditional
and conventional sources. Derivative/arbitrage programs and
insurance companies remained the dominant institutional buyers,
while individual retail purchases also remained strong. Traditional,
open-end tax-exempt mutual funds have continued to see significant
disintermediation. It was recently reported that thus far during the
2000 calendar year, long-term municipal bond mutual funds
experienced net cash outflows of more than $15 billion. Fortunately,
the combination of reduced new bond issuance and ongoing demand from
non-traditional sources has been able to more than offset the
decline in demand from tax-exempt mutual funds. This favorable
balance has fostered a significant decline in municipal bond yields
in recent months.

Currently, there is no reason to expect that the positive technical
position of the municipal bond market will significantly
deteriorate. The steeply positive yield curve and the relatively
high credit quality that the tax-exempt bond market offers should
continue to attract different classes of institutional buyers.
Strong state and local governmental financial conditions also
suggest that issuance should remain manageable into next year.

However, the results of the presidential election may affect the tax-
exempt bond market. Various tax and spending programs proposed by
both candidates have obvious implications for state and local
governments as well as corporate and individual taxpayers. Political
history has shown that the enactment of campaign promises, both
Republican and Democratic, has very often been a long, laborious
process. This suggests that over the next few months US economic
factors will most likely have a greater effect on bond yields than
political considerations.


Portfolio Strategy
During the six months ended October 31, 2000, the reduction in
overall bond issuance and declining bond yields limited portfolio
activity. We attempted to maintain the market neutral position we
adopted late last year by adding some interest rate-sensitive issues
to the Fund. As tax-exempt bond yields declined in recent months,
the market value of many of the Fund's holdings appreciated to such
an extent that additional market gains were limited. Some of these
issues were sold both to capture recent gains to the Fund's net
asset value and prevent the Fund from developing an overtly
defensive structure. The purchase of the more aggressively
structured securities returned the Fund to a more neutral market
position.

The Fund remained fully invested throughout the six-month period
ended October 31, 2000. A strategy of maintaining significant cash
reserves remains undesirable as it reduces shareholder income and,
given recent and expected future declines in tax-exempt bond
issuance, becomes problematic to quickly reinvest. We do not expect
any additional tightening actions by the Federal Reserve Board.
Furthermore, recent signs of a moderating US economy suggests that a
significant and protracted increase in fixed-income bond yields is
unlikely before year-end. In such an environment, we expect to
remain fully invested and use any periods of volatility as
opportunities to seek to enhance the Fund's dividend yield.

The 125 basis point increase in short-term interest rates engineered
by the Federal Reserve Board during the past year resulted in an
increase in the Fund's borrowing cost into the 4%--4.125% range.
However, despite this increase, the tax-exempt yield curve remained
steeply positive, generating a material income benefit to the Fund's
Common Stock shareholders from leveraging of the Preferred Stock.
However, should the spread between short-term and long-term tax-
exempt interest rates narrow, the benefits of the leverage will
decline and, as a result, reduce the yield on the Fund's Common
Stock. (For a complete explanation of the benefits and risks of
leveraging, see page 1 of this report to shareholders.)

MANAGED DIVIDEND POLICY

The Fund's dividend policy is to distribute all or a portion of its
net investment income to its shareholders on a monthly basis. In
order to provide shareholders with a more consistent yield to the
current trading price of Common Stock of the Fund, the Fund may at
times pay out less than the entire amount of net investment income
earned in any particular month and may at times in any month pay out
such accumulated but undistributed income in addition to net
investment income earned in that month. As a result, the dividends
paid by the Fund for any particular month may be more or less than
the amount of net investment income earned by the Fund during such
month. The Fund's current accumulated but undistributed net
investment income, if any, is disclosed in the Statement of Assets,
Liabilities and Capital, which comprises part of the Financial
Information included in this report.

exchanges, are valued at their closing 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-counter-market, valuation is the last
asked price (options written) or the last bid price (options
purchased). Securities 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.

NOTES TO FINANCIAL STATEMENTS (concluded)


* 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 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 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.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates. Distributions in excess of
realized capital gains are due primarily to differing tax treatments
for futures transactions.
