DEAR SHAREHOLDER

Economic Environment
The US economy continued to expand at an above-trend pace for the
three months ended May 31, 1998. Despite declining export growth and
a relatively high real interest rate environment, gross domestic
product (GDP) rose 5.4% in the first quarter of 1998, marking the
sixth consecutive quarter that the annualized growth rate of GDP has
exceeded 3.0%. Consumer spending, which has more than offset the
trade drag resulting from the Asian economic crisis, rose 6.1% in
the first quarter and has been largely responsible for the strong
showing of the US economy. Nonetheless, despite continued overall
economic strength, the Federal Reserve Board refrained from raising
interest rates during the May quarter.

Two fundamental catalysts contributing to the surge in consumer
spending have been the strength of the job market and the strength
of the US equity market. With an average gain of 245,000 new jobs
per month through the first five months of 1998, employment growth
in the United States remains strong. As a result, the unemployment
rate has fallen to a 28-year low of 4.3%. More important, labor
costs continue to trend upward. Average hourly earnings rose 4.3%
over the 12 months ended May 31, 1998, the highest year-over-year
pace in the current economic expansion and well above the current
rate of inflation. Consumer spending has also been influenced by the
strength of the US stock market. In the three years since December
1994, the overall net wealth of US households has risen 38% in
response to the climb of equity prices. As a result, US households
are spending more and saving less of their personal income, while
still seeing their overall net wealth increase.

The strength of consumer demand has carried over to other sectors of
the economy as well. Reflecting a confluence of favorable factors
(low mortgage rates, strong income growth and high consumer
confidence), housing remains exceptionally strong. New housing
starts rose to an annualized 1.58 million-unit rate in the first
quarter of 1998, the fastest pace in ten years. In addition, both
new and existing home sales are currently at or near record levels.
Despite rising wage growth and strong domestic demand, the lack of
corporate pricing power has kept inflation subdued. During the 12-
month period ended May 31, 1998, the consumer price index rose just
1.5%, while the producer price index fell 1.2%.

Although the Asian currency crisis is likely to continue to hamper
export growth and act as a drag on GDP, we do not expect consumer
spending to slow significantly in the second half of 1998, barring a
major stock market correction. Since domestic demand accounts for
nearly two-thirds of GDP, we expect economic growth to remain
moderately strong through-out 1998. Meanwhile, should labor markets
tighten further, the current benign inflationary environment could
be threatened by escalating wage pressures. Consequently, we believe
that the risk of a tightening in monetary policy by the Federal
Reserve Board has increased and that interest rates could rise in
the near term.

Fiscal Year in Review
A difficult market environment marked the Fund's fiscal year ended
May 31, 1998. Declining interest rates coupled with a flattening of
the US Treasury yield curve prompted a substantial rise in
prepayments of adjustable rate mortgage securities (ARMS). Since
most ARMS trade at premium prices, high prepayments have a negative
effect on the yield of ARMS. As a result, ARMS yield spreads
widened, and prices declined to compensate for the increase in
prepayments.

As of the close of the 12-month period ended May 31, 1998, the one-
year US Treasury bill fell 35 basis points (0.35%) to 5.41% while
the 30-year Treasury bond fell 111 basis points to 5.80%. Four
primary factors contributed to the change in the interest rate
environment during the year. First, as the rate of inflation
decelerated, investors became more comfortable with the prospect of
a continued low-inflation environment and pushed interest rates down
accordingly. Second, the effects of the Asian economic crisis
prompted a flight to quality toward the US financial markets,
causing bond market yields to move lower. Third, the robust US
economy brought unanticipated excess revenue to the Federal
Government in the form of additional tax receipts. As a result, it
is expected that the Federal Government will post a budget surplus
in 1998, the first such surplus in 29 years. Consequently, it is
anticipated that the US Treasury will need to issue fewer securities
resulting in a technical supply and demand situation, which has
exerted a downward influence on interest rates. Finally, since
Federal Reserve Board monetary policy remained unchanged, short-term
interest rates essentially remained stable as investors pegged short-
term interest rates to the Federal Reserve Board policy directive.
Hence, as long-term interest rates declined, short-term and long-
term Treasury rates narrowed, causing the US Treasury yield curve to
flatten.

Despite the presence of a difficult market environment for ARMS, we
took several steps to limit prepayment risk and improve performance
to the Fund. We continued to emphasize "seasoned" ARMS as the core
holdings in our portfolio. Seasoned ARMS are typically less
prepayment sensitive to a major refinancing wave for several
reasons. First, many seasoned ARMS were originated with interest
rates much higher than their current interest rate. As a result,
mortgage payments of these ARMS today are less than at origination.
Second, homeowners with seasoned adjustable rate mortgages have had
numerous opportunities to refinance in even lower interest rate
environments. Finally, seasoned ARMS typically have smaller loan
balances. Consequently, refinancing into a fixed-rate mortgage
offers very little in savings, which reduces the incentive to
refinance. Our strategy has proven successful, as the prepayments of
our seasoned ARMS holdings have been quite stable. During the
period, we took advantage of the widening between the London
Interbank Offered Rate (LIBOR) curve and US Treasury curve, by
increasing our holdings of LIBOR and certificates of deposit indexed
ARMS. At May 31, 1998, LIBOR ranged from 43 basis points to 68 basis
points more than similar maturity Treasury rates. These strategies
helped to stabilize the Fund's total return in a difficult market
environment.

Looking ahead, we expect ARMS to perform well as prepayments begin
to decline. By May 31, 1998, the Mortgage Bankers Association
Refinance Index had fallen by roughly two-thirds from its peak in
mid-January 1998. We expect this to translate into slower ARMS
prepayment speeds. In addition, the decline in interest rates is
likely to cause ARMS coupons to reset slightly downward. We believe
this provides an additional incentive for homeowners to refrain from
refinancing, the result of their mortgage payments moving lower.
Finally, a positive technical situation has developed in the ARMS
market. The recent refinancing wave has caused the origination and
outstanding availability of ARMS to decline significantly. According
to the Federal Home Loan Mortgage Corporation, just 5% of the
mortgages originated so far in 1998 are ARMS. As such, we believe
there is a tremendous opportunity for ARMS yield spreads to narrow
and prices to rise in the second half of 1998.

In Conclusion
We thank you for your continued investment in Merrill Lynch
Adjustable Rate Securities Fund, Inc., and we look forward to
discussing our outlook and strategy with you in our upcoming
quarterly report to shareholders.

PERFORMANCE DATA

About Fund
Performance

Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers four pricing
alternatives:

* Class A Shares incur a maximum initial sales charge (front-end
  load) of 4% and bear no ongoing distribution or account maintenance
  fees. Class A Shares are available only to eligible investors, as
  detailed in the Fund's prospectus. If you were a Class A shareholder
  prior to October 21, 1994, your Class A Shares were redesignated to
  Class D Shares on October 21, 1994. However, in the case of certain
  eligible investors, the shares were simultaneously exchanged for
  Class A Shares.

* Class B Shares are subject to a maximum contingent deferred sales
  charge of 4% if redeemed during the first year, decreasing 1% each
  year thereafter to 0% after the fourth year. In addition, Class B
  Shares are subject to a distribution fee of 0.50% and an account
  maintenance fee of 0.25%. These shares automatically convert to
  Class D Shares after approximately 10 years. (There is no initial
  sales charge for automatic share conversions.)

* Class C Shares are subject to a distribution fee of 0.55% and an
  account maintenance fee of 0.25%. In addition, Class C Shares are
  subject to a 1% contingent deferred sales charge if redeemed within
  one year of purchase.

* Class D Shares incur a maximum initial sales charge of 4% and an
  account maintenance fee of 0.25% (but no distribution fee).

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Average Annual Total
Return" tables assume reinvestment of all dividends and capital
gains distributions at net asset value on the payable date.
Investment return and principal value of shares will fluctuate so
that shares, when redeemed, may be worth more or less than their
original cost. Dividends paid to each class of shares will vary
because of the different levels of account maintenance, distribution
and transfer agency fees applicable to each class, which are
deducted from the income available to be paid to shareholders.

              *Adjustable Rate Obligations have coupon rates which reset
               periodically.
             **Mortgage-Backed Obligations are subject to principal paydowns as a
               result of prepayments or refinancings of the underlying mortgage
               instruments. As a result, the average life may be substantially less
               than the original maturity.
            ***Repurchase Agreements are fully collateralized by US Government &
               Agency Obligations.
            (a)Real Estate Mortgage Investment Conduits (REMIC).
            (b)Securities which receive some or all of the interest portion of
               the underlying collateral and little or no principal. Interest only
               securities have either a nominal or a notional amount of principal.
            (c)Adjustable rate coupon that resets inversely to changes in the
               London Interbank Offered Rate.

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
Merrill Lynch Adjustable Rate Securities Fund, Inc. (the "Fund") is
registered under the Investment Company Act of 1940 as a
diversified, open-end management investment company. The Fund offers
four classes of shares under the Merrill Lynch Select Pricing SM
System. Shares of Class A and Class D are sold with a front-end
sales charge. Shares of Class B and Class C may be subject to a
contingent deferred sales charge. All classes of shares have
identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class B, Class C and Class D
Shares bear certain expenses related to the account maintenance of
such shares, and Class B and Class C Shares also bear certain
expenses related to the distribution of such shares. Each class has
exclusive voting rights with respect to matters relating to its
account maintenance and distribution expenditures. The following is
a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Portfolio securities which are traded
in the over-the-counter market are valued at the last available bid
price or on the basis of yield equivalents as obtained from one or
more dealers that make markets in such securities. Options written
on mortgage-backed securities and other securities of the Fund which
are traded on exchanges are valued at their last sale price in the
case of exchange-traded options or, in the case of options traded in
the over-the-counter market, the last asked price. Options purchased
by the Fund are valued at their last sale price in the case of
exchange-traded options or, in the case of options traded in the
over-the-counter market, the last bid price. Financial futures
contracts and options thereon, which are traded on exchanges, are
stated at market value. Securities 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.

(b) Repurchase agreements--The Fund invests in US Government
securities pursuant to repurchase agreements with a member bank of
the Federal Reserve System or a primary dealer in US Government
securities. Under such agreements, the bank or primary dealer agrees
to repurchase the security at a mutually agreed upon time and price.
The Fund takes possession of the underlying securities, marks to
market such securities and, if necessary, receives additions to such
securities daily to ensure that the contract is fully
collateralized.

(c) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Options--The Fund is authorized to purchase and write covered call
and 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.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and related 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
margins 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.

(d) 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.




Merrill Lynch Adjustable Rate Securities Fund, Inc., May 31, 1998




NOTES TO FINANCIAL STATEMENTS (continued)


(e) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income (including amortization of
discount and premiums) is recognized on the accrual basis. Realized
gains and losses on security transactions are determined on the
identified cost basis.

(f) Prepaid registration fees--Prepaid registration fees are charged
to expense as the related shares are issued.

(g) Dividends and distributions--All or a portion of the Fund's net
investment income is declared daily and paid monthly. Distributions
paid by the Fund are recorded on the ex-dividend dates.

(h) Dollar rolls--The Fund sells mortgage-backed securities for
delivery in the current month and simultaneously contracts to
repurchase substantially similar (same type, coupon and maturity)
securities on a specific future date.


2. Investment Advisory Agreement and Transactions
with Affiliates:
The Fund has entered into an Investment Advisory Agreement with
Merrill Lynch Asset Management, L.P. ("MLAM"). The general partner
of MLAM is Princeton Services, Inc. ("PSI"), an indirect wholly-

the limited partner. The Fund has entered into a Distribution
Agreement and Distribution Plans with Merrill Lynch Funds
Distributor, Inc. ("MLFD" or the "Distributor"), a wholly-owned
subsidiary of Merrill Lynch Group, Inc.

MLAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee of 0.50%, on an annual basis,
of the average daily value of the Fund's net assets.

Pursuant to the Distribution Plans adopted by the Fund in accordance
with Rule 12b-1 under the Investment Company Act of 1940, the Fund
pays the Distributor ongoing account maintenance and distribution
fees. The fees are accrued daily and paid monthly at annual rates
based upon the average daily net assets of the shares as follows:

Class D                                0.25%           --


Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Inc. ("MLPF&S"), a subsidiary of ML & Co.,
also provides account maintenance and distribution services to the
Fund. The ongoing account maintenance fee compensates the
Distributor and MLPF&S for providing account maintenance services to
Class B, Class C and Class D shareholders. The ongoing distribution
fee compensates the Distributor and MLPF&S for providing shareholder
and distribution-related services to Class B and Class C
shareholders.

and MLPF&S earned dealer concessions on sales of the Fund's Class D
