MERRILL LYNCH FEDERAL SECURITIES TRUST


DEAR SHAREHOLDER


Economic Environment
During the quarter ended August 31, 1998, mounting global financial
concerns prompted an enormous flight to quality toward the US
Treasury market, pushing US Treasury bond yields to their lowest
levels in 30 years. The effects of the economic crisis in Asia began
to impact other regional economies as well. As a result,
deteriorating economic fundamentals in Russia caused the ruble to
decline by more than 90% and sharply increased the risks of
contagion in the emerging market economies of Latin America and
South America.

Despite heightened global economic turmoil, the US economy continued
to exhibit an impressive resiliency during the second quarter of
1998. US gross domestic product (GDP) rose 1.6% during the second
quarter, although there was a sharp reduction in inventory
accumulation and the worst trade deficit reported in US history,
which subtracted 2.1% from second-quarter GDP. Consumer spending,
which rose 5.8% in the second quarter, remains the driving force
behind US economic growth. Housing also continues to surge, as new
housing starts rose to a 1.72 million unit annual rate in July, the
highest level in more than 11 years. In addition, more single-family
homes are being built now than at any time since 1979. Retail sales
have also been strong and reflect the high volume of new home sales,
since the demand for furniture and appliances soared. Consequently,
retail sales (excluding automobile sales) rose at a robust 4.9%
annual rate over the three-month period ended July 31, 1998. Despite
strong consumer demand, inflationary pressures remain stagnant. The
consumer price index for July was up just 1.7% from a year ago,
while the producer price index for July fell 0.3% compared to the
same period last year.

As a result of a degenerating set of global economic fundamentals,
increased world stock market volatility put greater pressure on
global liquidity. Consequently, the risks of a future downturn in US
economic growth increased as the Asian region remains mired in a
recession. Deteriorating political and economic conditions forced
the Russian government to devalue its currency and default on its
debt payments in August, spurring a massive flight to quality toward
the US Treasury market and intensifying the global credit crunch by
raising the risk premium for all emerging market economies. In
addition, Canada raised interest rates in August to support its
weakening currency, which could slow economic activity. Since South
America, Latin America and Canada account for approximately 40% of
US exports, any extensive economic downturn in these regions could
depress future US economic growth.

In spite of the current reports of strong economic growth in the
United States, we believe the Federal Reserve Board has focused its
attention toward the deepening instability in the world's financial
markets and the resulting liquidity crunch. Ultimately, restrictive
financial conditions, coupled with deflationary forces, could
eventually hamper US economic growth prospects. As a result, we
believe the Federal Reserve Board could begin easing monetary policy
and lower interest rates. (The Federal Reserve Board did lower the
Federal Funds rate by 25 basis points (0.25%) to 5.25% at the end of
September.) We would expect this scenario to have positive
ramifications for the US bond market.


Fiscal Year in Review
During the year ended August 31, 1998, interest rates moved
substantially lower. US Treasury securities with maturities of 5
years, 10 years and 30 years were all lower in yield by
approximately 140 basis points. The one-year Treasury bill fell by
71 basis points while the three-month bill moved 38 basis points
lower. The yield curve continued to flatten, creating a yield
differential of just 42 basis points between the three-month
Treasury bill (4.83%) and the 30-year Treasury bond (5.25%) by
August 31, 1998. This established a difficult environment for
mortgage-backed securities (MBS).

During the 12-month period, low interest rates, coupled with
mortgage banker sophistication in terms of refinancing, led to
prepayment fears and an underperformance of MBS compared to Treasury
securities. Compounding the problem was the decoupling between
Treasury yields and yields on MBS, as global concerns and the
resulting flight to quality caused yield spreads to widen. Corporate
securities and other credit-sensitive issues were the hardest hit,
but MBS were also affected, even those issued by Government National
Mortgage Association (GNMA), Federal National Mortgage Association
(FNMA) and Federal Home Loan Mortgage Corporation (FHLMC).


Merrill Lynch Federal Securities Trust
August 31, 1998


Throughout the period, the Fund was well positioned for the decline
in interest rates and was generally structured to avoid those MBS
with the greatest prepayment uncertainty. The Fund had large
positions in low-coupon MBS with little or no refinancing incentive,
and significant holdings in multi-family MBS that have prepayment
lockouts and yield maintenance provisions. Also, the Fund maintained
a strong focus on GNMA MBS, which are comprised of Federal Housing
Administration/Veteran's Administration mortgages that tend to
prepay slower than conventional mortgages. The Fund also had a small
position in super-seasoned, high-coupon MBS where the homeowner has
not responded to past refinancing incentives.

For most of the year, we focused on establishing a balance between
yield and total return characteristics. Although performance was
good during the year, it was hampered by our focus on MBS, which
lagged Treasury performance. Also, we shifted 30-year MBS to 15-year
MBS, expecting the yield curve to steepen. However, the yield curve
flattened, and 30-year MBS outperformed 15-year MBS. Lastly, a
significant portion of the Fund was invested in FNMA and FHLMC multi-
family MBS. These securities were purchased as Treasury surrogates
for their excellent convexity characteristics (good price
appreciation during declining interest rates) because of prepayment
lockouts and yield maintenance provisions. However, as spreads
widened, these securities did not perform as well as Treasury
securities.


Portfolio Strategy
We continue to believe that MBS offer attractive investment
opportunities. For example, a FNMA 6.50% MBS that trades just above
par at about $100.50 would seem very attractive when compared to
five-year and ten-year Treasury security yields of 4.79% and 4.97%,
respectively. This wide yield spread is especially attractive at
current low interest rate levels. The Fund is capturing this
relative value by being 98% invested in MBS. Of that percentage, 22%
is invested in multi-family MBS. While this structure offers a high
yield, yield pays out over time, whereas price movements are
immediate. However, a significant further decline in longer-term
interest rates does not appear as likely as a spread tightening at
this time. We believe the Fund is well-positioned if yield spreads
do tighten because we have locked in attractive yields and would
receive better price movement as well.


In Conclusion
We thank you for your continued investment in Merrill Lynch Federal
Securities Trust, and we look forward to reviewing our outlook and
strategy with you in our upcoming quarterly report to shareholders.

Sincerely,

PERFORMANCE DATA


About Fund Performance

Investors are able to purchase shares of the Trust 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 "Recent Performance
Results" and "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.

Merrill Lynch Federal Securities Trust
August 31, 1998


NOTES TO FINANCIAL STATEMENTS



1. Significant Accounting Policies:
Merrill Lynch Federal Securities Trust (the "Trust") is registered
under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The Trust 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 Trust.

(a) Valuation of investments--Securities traded in the over-the-
counter market 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. The Trust employs Merrill Lynch Securities Pricing
Service ("MLSPS"), an affiliate of Fund Asset Management, L.P.
("FAM"), to provide mortgage-backed securities prices for the Trust.
Options on US Government securities, which are traded on exchanges,
are valued at their last bid price in the case of options purchased
by the Trust and their last asked price in the case of options
written by the Trust. An option traded on the over-the-counter
market is valued at its last bid price or asked price as obtained by
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 last sale price as of the close of
such exchanges. Securities with a remaining maturity of sixty days
or less are valued on an amortized cost basis, 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 Trustees of the Trust.

(b) Repurchase agreements--The Trust invests in US Government
securities pursuant to repurchase agreements. Under such agreements,
the counterparty agrees to repurchase the security at a mutually
agreed upon time and price. The Trust takes possession of the
underlying securities, marks to market such securities and, if
necessary, receives additional securities daily to ensure that the
contract is fully collateralized.

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

* Futures contracts--The Trust may purchase or sell financial
futures contracts. Upon entering into a contract, the Trust deposits
and maintains as collateral such initial margins as required by the
exchange on which the transaction is effected. 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 value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Trust as unrealized gains or losses. When
the contract is closed, the Trust 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 is was closed.

* Options--The Trust is authorized to write and purchase call and
put options. When the Trust writes an option, an amount equal to the
premium received by the Trust 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 Trust enters into a closing transaction), the Trust
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 premiums paid or received).


Merrill Lynch Federal Securities Trust
August 31, 1998


Written and purchased options are non-income producing investments.

(d) Income taxes--It is the Trust'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.

(e) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Dividend income is recorded on the ex-
dividend dates. Interest income (including amortization of discount)
and extended delivery fees are 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--Dividends from net investment
income are declared daily and paid monthly. Distributions of capital
gains are recorded on the ex-dividend dates.

(h) Dollar rolls--The Trust 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. As of August 31, 1998, no
dollar rolls were in effect.


2. Investment Advisory Agreement and
Transactions with Affiliates:
The Trust has entered into an Investment Advisory Agreement with
FAM. The general partner of FAM is Princeton Services, Inc. ("PSI"),
an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc.
("ML & Co."), which is the limited partner. The Trust has also
entered into a Distribution Agreement and Distribution Plans with
Merrill Lynch Funds Distributor ("MLFD" or "Distributor"), a
division of Princeton Funds Distributor, Inc. ("PFD"), which is a
wholly-owned subsidiary of Merrill Lynch Group, Inc.

FAM is responsible for the management of the Trust's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Trust. For such
services, the Trust pays a monthly fee based upon the average daily
value of the Trust's net assets at the following rate:

exceeding $3.5 billion                              0.375%

In excess of $3.5 billion but not
exceeding $5 billion                                0.350%

In excess of $5 billion but not
exceeding $6.5 billion                              0.325%

Exceeding $6.5 billion                              0.300%

Pursuant to the Distribution Plans adopted by the Trust in
accordance with Rule 12b-1 under the Investment Company Act of 1940,
the Trust 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:

                          Account        Distribution
                      Maintenance Fee         Fee
