A Letter From the President


Dear Shareholder

On balance, 2005 was a year of "muddling through" for the U.S. financial
markets, as oil prices reached new record highs, the Federal Reserve Board
(the Fed) increased the target federal funds rate from 2.25% to 4.25%, the
housing market and the consumer finally showed some signs of slowing, and
Hurricanes Katrina and Rita ravaged the Gulf Coast, causing yet untold
economic damage.

Although they struggled, stocks managed to post their third straight year of
positive performance. The year was equally uncertain for fixed income
markets, which were bemused by a flattening yield curve and a number of
significant credit events that brought a slowdown in high yield market
returns. Notably, the one-year results for the major asset classes - stocks,
bonds and cash - were the closest they have been in more than 100 years. For
the 12- and six-month periods ended December 31, 2005, most of the major
market indexes managed to land in positive territory:



Total Returns as of December 31, 2005                                 6-month        12-month
                                                                                
U.S. equities (Standard & Poor's 500 Index)                            + 5.77%        + 4.91%
Small-cap U.S. equities (Russell 2000 Index)                           + 5.88         + 4.55
International equities (MSCI Europe Australasia Far East Index)        +14.88         +13.54
Fixed income (Lehman Brothers Aggregate Bond Index)                    - 0.08         + 2.43
Tax-exempt fixed income (Lehman Brothers Municipal Bond Index)         + 0.60         + 3.51
High yield bonds (Credit Suisse First Boston High Yield Index)         + 1.48         + 2.26



In hindsight, these numbers are reasonably good given the headwinds facing
the markets in 2005. U.S. equities found support in strong corporate
earnings, low core inflation and healthy company balance sheets. Strength in
the global economy and non-U.S. equity markets helped, as did robust dividend-
distribution, share-buyback and merger-and-acquisition activity. International
stocks had an excellent year, with many markets benefiting from strong economic
statistics, trade surpluses and solid finances. In the U.S. bond market,
long-term yields remained low and, at year-end, the Treasury curve appeared
ready to invert.

As 2006 begins, the largest question marks center on the Fed's future moves,
the U.S. consumer's ability (or inability) to continue spending, the direction
of the U.S. dollar following a year of appreciation and the potential for
continued strong economic and corporate earnings growth. As you turn the
calendar and consider how these factors might impact your investments, remember
that the new year is a good time to meet with your financial advisor to review
your financial goals, and to make portfolio changes where necessary. For
investing insights and timely "food for thought" for investors, we also invite
you to visit Shareholder magazine at www.mlim.ml.com/shareholdermagazine.

As always, we thank you for trusting Merrill Lynch Investment Managers with
your investment assets, and we look forward to serving you in the new year
and beyond.



Sincerely,



(Robert C. Doll, Jr.)

MERRILL LYNCH READY ASSETS TRUST                              DECEMBER 31, 2005



A Discussion With Your Fund's Portfolio Manager


We maintained a relatively conservative approach for much of the year as the
Fed continued to increase short-term interest rates, but are prepared to
adjust our strategy as the end of monetary tightening nears.


How did the Trust perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2005, Merrill Lynch Ready Assets
Trust paid shareholders a net annualized dividend of 2.57%. For the six-month
period ended December 31, 2005, the Trust paid shareholders a net annualized
dividend of 3.10%. At December 31, 2005, Ready Assets Trust had a seven-day
yield of 3.57%.

The Trust's average portfolio maturity at December 31, 2005 was 59 days,
compared to 60 days at June 30, 2005 and 52 days at December 31, 2004. The
average portfolio maturity ranged from a high of 67 days to a low of 44 days
during the fiscal year.

The economy remained quite resilient throughout the period, growing at an
annualized rate of 3.5% in the first quarter of 2005, 3.3% in the second
quarter and 4.1% in the third quarter (as measured by gross domestic product).
In light of the perceived economic strength, and in an effort to combat
inflation expectations, the Federal Reserve Board (the Fed) continued its
"measured" series of interest rate hikes. In all, the Fed raised rates in 25
basis point (.25%) increments eight times during the year, bringing the
federal funds rate to 4.25% at period-end.

Oil remained a hot topic for much of the period, although there was often
disagreement among market participants as to whether a $20 per barrel increase
in the price of oil posed a greater risk of inflation or a greater threat to
consumer spending. Consumer sentiment figures grew weaker as oil prices rose,
but Fed officials consistently warned that higher crude prices were sure to
result in pricing pressures. This supported their rate increases throughout
the year. Over the past 12 months, the two-year Treasury yield rose 133 basis
points from 3.08% to 4.41% as the 10-year Treasury yield rose just 15 basis
points from 4.24% to 4.39%. The result was a flattening of the yield curve.

Despite this dynamic, the steepness of the yield curve in the front end
offered enticing value. The greatest value seemed to be in the six-month, nine-
month and 12-month sectors. We were able to add higher yields to the portfolio
while still maintaining a relatively short average duration. This allowed us
to be constructive while limiting our interest rate exposure, an approach we
thought was prudent given the expectation for continued interest rate hikes.


How did you manage the portfolio during the fiscal year?

For the most part, we sought to add incremental yield and total return
potential to the portfolio by shifting our focus among maturities based on the
relative steepness of the yield curve in various sectors. As the year began,
our investment strategy was formulated on the premise that the Fed would
continue to advance its program of measured interest rate increases. We
primarily invested in 30-day commercial paper and floating rate securities in
an effort to maximize our ability to respond to higher short-term interest
rates. Floating rate securities, because their interest rates continuously
reset, provide protection in a rising interest rate environment.

At the mid-point of the fiscal year, our floating rate position represented
approximately 55% of portfolio assets. This was reduced to 46% by period-end
as the continued tightening of credit spreads made this asset class very
expensive. This was a result of increased demand but, even more so, was due to
a slowdown in agency issuance. New regulations forced the Federal National
Mortgage Association (Fannie Mae) to reduce its balance sheet. The fewer
mortgages Fannie Mae was permitted to own, the less borrowing it needed to do
in order to fund its holdings. Thus, discount notes outstanding, which had
been the agencies' primary tool of issuance, dipped significantly. With all of
this supply now missing from the market, spreads on short-term agency debt
collapsed. As we trimmed exposure to variable rate issues, the assets were
reallocated mostly to short-dated commercial paper and certificates of
deposit. This allowed us to maintain a shorter average duration and sustain
ample liquidity. Having significant overnight positions in a rising interest
rate environment proves beneficial because it is the most effective way to
meet redemptions while also allowing us to capitalize immediately when the Fed
raises interest rates.



MERRILL LYNCH READY ASSETS TRUST                              DECEMBER 31, 2005



With the remainder of the portfolio, we searched for sectors that were
attractively priced given the expectation for continued Fed interest rate
hikes. The two-year sector appeared quite expensive for much of the year,
while shorter sectors such as six months and 12 months offered much greater
value. Securities in this range offered attractive yields given the relative
steepness of the yield curve in the front end. Thus, our efforts to add
incremental yield to the portfolio were concentrated on these sectors for a
majority of the time, while we continued to target an average portfolio
duration in the somewhat conservative 60-day range.

As the Trust's fiscal period neared an end, we focused on liquidity in
anticipation of the cyclical year-end redemptions that normally occur as
shareholders require liquidity for consumer spending. In order to meet our
liquidity needs, we favored shorter-dated commercial paper with maturities of
three months or less.


How would you characterize the Trust's position at the close of the period?

Although Hurricanes Katrina and Rita seemed to pose a legitimate threat to
economic growth, the fixed income markets dismissed this as a temporary shock.
It seems the economy is strong enough to absorb a brief slowdown, and the
combination of lofty oil prices and the rebuilding efforts in the Gulf Coast
region may justify even higher rates. In fact, as the period came to an end,
the markets appeared resigned to the idea that short-term interest rates will
move higher, at least until Dr. Ben Bernanke assumes his role as Fed Chairman
on January 31, and probably afterward if the new chairman feels the need to
establish his inflation-fighting credentials.

In the near term, we expect to keep the Trust's average portfolio maturity in
the 55-day - 60-day range, with most investments in the one-month - two-month
sector. However, once the Fed has communicated to the markets that "neutral"
policy has been achieved, we would expect the spread between the federal funds
rate and the two-year Treasury yield, which is typically positively sloped, to
invert. We will look to reposition the portfolio prior to this occurrence.
Specifically, we would look to barbell the portfolio, purchasing six-month
money market securities on the shorter end of the barbell and two-year
Treasury issues on the longer end.

December and as of our last report to shareholders is detailed below:

Disclosure of Expenses


Shareholders of this Trust may incur the following charges: (a) expenses
related to transactions, including sales charges, redemption fees and exchange
fees; and (b) operating expenses including advisory fees, distribution fees
including 12b-1 fees, and other Trust expenses. The following example (which
is based on a hypothetical investment of $1,000 invested on July 1, 2005 and
held through December 31, 2005) is intended to assist shareholders both in
calculating expenses based on an investment in the Trust and in comparing
these expenses with similar costs of investing in other mutual funds.

The first table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid during
the period covered by this report, shareholders can divide their account value
by $1,000 and then multiply the result by the number in the first line under
the heading entitled "Expenses Paid During the Period."

The second table below provides information about hypothetical account values
and hypothetical expenses based on the Trust's actual expense ratio and an
assumed rate of return of 5% per year before expenses. In order to assist
shareholders in comparing the ongoing expenses of investing in this Trust and
other funds, compare the 5% hypothetical example with the 5% hypothetical
examples that appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders'
ongoing costs only and do not reflect any transactional expenses, such as
sales charges, redemption fees or exchange fees. Therefore, the second table
is useful in comparing ongoing expenses only, and will not help shareholders
determine the relative total expenses of owning different funds. If these
transactional expenses were included, shareholder expenses would have been
higher.



                                                                                          Expenses Paid

Notes to Financial Statements


1. Significant Accounting Policies:
Merrill Lynch Ready Assets Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Trust's financial statements are prepared
in conformity with U.S. generally accepted accounting principles, which may
require the use of management accruals and estimates. Actual results may
differ from these estimates. The following is a summary of significant
accounting policies followed by the Trust.

(a) Valuation of investments--Portfolio securities with remaining maturities
of greater than sixty days, for which market quotations are readily available,
are valued at market value. As securities transition from sixty-one to sixty
days to maturity, the difference between the valuation existing on the sixty-
first day before maturity and maturity value is amortized on a straight-line
basis to maturity. Securities maturing sixty days or less from their date of
acquisition are valued at amortized cost, which approximates market value. For
purposes of valuation, the maturity of a variable rate security is deemed to
be the next coupon date on which the interest rate is to be adjusted. Other
investments and assets for which market quotations are not available are
valued at fair value as determined in good faith by or under the direction of
the Board of Trustees.

(b) Repurchase agreements--The Trust may invest in U.S. 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 additions to such securities daily to
ensure that the contract is fully collateralized. If the counterparty defaults
and the fair value of the collateral declines, liquidation of the collateral
by the Trust may be delayed or limited.

(c) 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.

(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 (including amortization of premium and
discount) is recognized on the accrual basis.

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

(f) Dividends and distributions to shareholders--The Trust declares dividends
daily and reinvests daily such dividends (net of non-resident alien tax and
backup withholding tax) in additional shares of beneficial interest at net
asset value. Dividends are declared from net investment income and
distributions from net realized gain or loss on investments.

(g) Securities lending--The Trust may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities.
The market value of the loaned securities is determined at the close of
business of the Trust and any additional required collateral is delivered to
the Trust on the next business day. Where the Trust receives securities as
collateral for the loaned securities, it receives a fee from the borrower. The
Trust typically receives the income on the loaned securities, but does not
receive the income on the collateral. Where the Trust receives cash
collateral, it may invest such collateral and retain the amount earned on such
investment, net of any amount rebated to the borrower. Loans of securities are
terminable at any time and the borrower, after notice, is required to return
borrowed securities within five business days. The Trust may pay reasonable
finder's, lending agent, administrative and custodial fees in connection with
its loans. In the event that the borrower defaults on its obligation to return
borrowed securities because of insolvency or for any other reason, the Trust
could experience delays and costs in gaining access to the collateral. The
Trust also could suffer a loss where the value of the collateral falls below
the market value of the borrowed securities, in the event of borrower default
or in the event of losses on investments made with cash collateral.

Notes to Financial Statements (concluded)


2. Investment Advisory Agreement and Transactions with Affiliates:
The Trust has entered into an Investment Advisory Agreement with Merrill Lynch
Investment Managers, L.P. ("MLIM"). The general partner of MLIM 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 Plan with FAM
Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly-owned
subsidiary of Merrill Lynch Group, Inc.

MLIM provides the Trust with investment management, research, statistical and
advisory services, and pays certain other expenses 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 annual rates:


Portion of average daily value of net assets:                  Rate

Not exceeding $500 million                                    .500%
In excess of $500 million but not exceeding $1 billion        .400%
In excess of $1 billion but not exceeding $5 billion          .350%
In excess of $5 billion but not exceeding $10 billion         .325%
In excess of $10 billion but not exceeding $15 billion        .300%
In excess of $15 billion but not exceeding $20 billion        .275%
In excess of $20 billion                                      .250%


Pursuant to the Distribution and Shareholder Servicing Plan in compliance with
Rule 12b-1 under the Investment Company Act of 1940, Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of MLIM, receives a
distribution fee from the Trust. The fee is accrued daily and paid monthly at
the annual rate of .125% of average daily net assets of the Trust for
shareholders whose Trust accounts are serviced by MLPF&S financial advisors,
whether maintained through MLPF&S or directly with the Trust's transfer agent.
The distribution fee is to compensate MLPF&S for providing, or arranging for
the provision of, account maintenance and sales and promotional activities and
services with respect to shares of the Trust. For the year ended December 31,
2005, MLPF&S earned $4,451,278 under the Shareholder Servicing Plan.

The Trust has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to MLPF&S or its
affiliates. Pursuant to that order, the Trust also has retained Merrill Lynch
Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, as the
securities lending agent for a fee based on a share of the returns on
investment of cash collateral. MLIM, LLC may, on behalf of the Trust, invest
cash collateral received by the Trust for such loans, among other things, in a
private investment company managed by MLIM, LLC or in registered money market
funds advised by MLIM or its affiliates.

For the year ended December 31, 2005, the Trust reimbursed MLIM $94,501 for
certain accounting services.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Trust's transfer agent.

Certain officers and/or trustees of the Trust are officers and/or directors of
MLIM, FDS, PSI, FAMD, ML & Co., and/or MLIM, LLC.


3. Shares of Beneficial Interest:
The number of shares sold, reinvested and redeemed during the years
corresponds to the amounts included in the Statements of Changes in Net Assets
for net proceeds from sale of shares, value of shares reinvested and cost of
shares redeemed, respectively, since shares are recorded at $1.00 per share.


4. Distributions to Shareholders:
The tax character of distributions paid during the fiscal years ended December
31, 2005 and December 31, 2004 was as follows:



                                          12/31/2005     12/31/2004

Distributions paid from:
   Ordinary income                    $  107,179,118   $   37,532,952
   Net long-term capital gains                    --            7,417
                                      --------------   --------------
Total taxable distributions           $  107,179,118   $   37,540,369
                                      ==============   ==============


As of December 31, 2005, the components of accumulated losses on a tax
basis were as follows:


Undistributed ordinary income--net                     $       24,296
Undistributed long-term capital gains--net                         --
                                                       --------------
Total undistributed earnings--net                              24,296
Capital loss carryforward                                          --
Unrealized losses--net                                   (2,660,093)*
                                                       --------------
Total accumulated losses--net                          $  (2,635,797)
                                                       ==============

* The difference between book-basis and tax-basis net unrealized
  losses is attributable primarily to the deferral of post-October
  capital losses for tax purposes.

Report of Independent Registered Public Accounting Firm


To the Shareholders and Board of Trustees of
Merrill Lynch Ready Assets Trust:

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of Merrill Lynch Ready Assets Trust as
of December 31, 2005, and the related statement of operations for the year
then ended, the statements of changes in net assets for each of the two years
in the period then ended and the financial highlights for each of the five
years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. The Trust is not required to have, nor were we engaged to
perform, an audit of its internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
Trust's internal control over financial reporting. Accordingly, we express no
such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
as well as evaluating the overall financial statement presentation. Our
procedures included confirmation of securities owned as of December 31, 2005
by correspondence with the custodian. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Merrill Lynch Ready Assets Trust as of December 31, 2005, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and its financial highlights for each
of the five years in the period then ended, in conformity with U.S. generally
accepted accounting principles.

Item 4 -   Principal Accountant Fees and Services

           (a) Audit Fees -     Fiscal Year Ending December 31, 2005 - $36,000
                                Fiscal Year Ending December 31, 2004 - $35,000

                                Fiscal Year Ending December 31, 2004 - $0

           (c) Tax Fees -       Fiscal Year Ending December 31, 2005 - $5,700
                                Fiscal Year Ending December 31, 2004 - $5,200

           The nature of the services include tax compliance, tax advice and

           (d) All Other Fees - Fiscal Year Ending December 31, 2005 - $0
                                Fiscal Year Ending December 31, 2004 - $0

           (e)(1) The registrant's audit committee (the "Committee") has
           adopted policies and procedures with regard to the pre-approval of
           services.  Audit, audit-related and tax compliance services
           provided to the registrant on an annual basis require specific pre-
           approval by the Committee.  The Committee also must approve other
           non-audit services provided to the registrant and those non-audit
           services provided to the registrant's affiliated service providers
           that relate directly to the operations and the financial reporting
           of the registrant.  Certain of these non-audit services that the
           Committee believes are a) consistent with the SEC's auditor
           independence rules and b) routine and recurring services that will
           not impair the independence of the independent accountants may be
           approved by the Committee without consideration on a specific case-
           by-case basis ("general pre-approval").  However, such services
           will only be deemed pre-approved provided that any individual
           project does not exceed $5,000 attributable to the registrant or
           $50,000 for all of the registrants the Committee oversees.  Any
           proposed services exceeding the pre-approved cost levels will
           require specific pre-approval by the Committee, as will any other
           services not subject to general pre-approval (e.g., unanticipated
           but permissible services).  The Committee is informed of each
           service approved subject to general pre-approval at the next
           regularly scheduled in-person board meeting.

           (f) Not Applicable

           (g) Fiscal Year Ending December 31, 2005 - $5,577,771
               Fiscal Year Ending December 31, 2004 - $11,926,355

           (h) The registrant's audit committee has considered and determined
           that the provision of non-audit services that were rendered to the
           registrant's investment adviser and any entity controlling,
           controlled by, or under common control with the investment adviser
           that provides ongoing services to the registrant that were not pre-
           approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of
           Regulation S-X is compatible with maintaining the principal
           accountant's independence.

           relating to the registrant is made known to us by others
           particularly during the period in which this report is being

           registrant's internal control over financial reporting.
