LETTER TO STOCKHOLDERS                      Overview

PERFORMANCE

For the six months ended June 30, 2004, the Morgan Stanley High Yield Fund, Inc.
(the "Fund") had a total return, based on net asset value per share of 1.83%
compared to 2.47% for the CSFB High Yield Index (the "Index"). On June 30, 2004,
the closing price of the Fund's shares on the New York Stock Exchange was $5.91,
representing a 13.3% discount to the Fund's net asset value per share.

FACTORS AFFECTING PERFORMANCE

   -   In the first half of 2004, the high-yield market benefited from a strong
       economic environment, good corporate earnings and very low defaults.
       Unfortunately, a poor technical situation caused by very large new
       issuance and outflows from the asset class kept high-yield from
       continuing the strong rally that began in late 2002.

   -   High-yield spreads tightened by 30 basis points during the period to
       close at 456 basis points over treasuries while the yield to maturity of
       the Index rose to 8.57% due to the significantly higher treasury yields.

   -   Lower-rated securities were the best performers during the period partly
       due to the decline in treasury prices, which had a greater impact on
       higher rated securities.

   -   Consumer products, metals, manufacturing and chemicals were the best
       performers industries with returns over 6% while aerospace and
       telecommunications produced negative returns. The airline industry, which
       is a sub-sector of aerospace, took a particularly hard hit, declining
       almost 20%. As the Fund did not own airlines in 2004, this benefited
       performance.

   -   Good security selection in housing, wireless communications and
       telecommunications added to relative performance during the first half of
       2004. Security selection in cable, forest products and chemicals
       detracted from returns.

MANAGEMENT STRATEGIES

   -   The Fund's main overweighted sectors are energy, housing and diversified
       media while our main sector underweights include airlines, financials,
       information technology, gaming/leisure and utilities. As a reminder, our
       sector allocations are the result of our bottom-up security selection.

   -   In regards to credit quality, the Fund has a slightly higher average
       credit quality than the overall market.

Sincerely,


/s/ Ronald E. Robison

                                            MORGAN STANLEY HIGH YIELD FUND, INC.

NOTES TO FINANCIAL STATEMENTS               June 30, 2004 (Unaudited)

     Morgan Stanley High Yield Fund, Inc. (the "Fund") was incorporated on
September 23, 1993 and is registered as a non-diversified, closed-end management
investment company under the Investment Company Act of 1940 (the "1940 Act"), as
amended. The Fund's primary objective is to produce high current income and as a
secondary objective, to seek capital appreciation, through investments primarily
in high yield securities.

A. ACCOUNTING POLICIES: The following significant accounting policies are in
conformity with accounting principles generally accepted in the United States.
Such policies are consistently followed by the Fund in the preparation of its
financial statements. Accounting principles generally accepted in the United
States may require management to make estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results may
differ from those estimates.

 1.  SECURITY VALUATION: Equity securities listed on a U.S. exchange are valued
     at the latest quoted sales price on the valuation date. Equity securities
     listed or traded on NASDAQ, for which market quotations are available, are
     valued at the NASDAQ Official Closing Price. Securities listed on a foreign
     exchange are valued at their closing price. Unlisted securities and listed
     securities not traded on the valuation date for which market quotations are
     readily available are valued at the mean between the current bid and asked
     prices obtained from reputable brokers. Bonds and other fixed income
     securities may be valued according to the broadest and most representative
     market. In addition, bonds and other fixed income securities may be valued
     on the basis of prices provided by a pricing service. The prices provided
     by a pricing service take into account broker dealer market price
     quotations for institutional size trading in similar groups of securities,
     security quality, maturity, coupon and other security characteristics as
     well as any developments related to the specific securities. Debt
     securities purchased with remaining maturities of 60 days or less are
     valued at amortized cost, if it approximates value.

     All other securities and investments for which market values are not
     readily available, including restricted securities, and those securities
     for which it is inappropriate to determine prices in accordance with the
     aforementioned procedures, are valued at fair value as determined in good
     faith under procedures adopted by the Board of Directors, although the
     actual calculations may be done by others. Factors considered in making
     this determination may include, but are not limited to, information
     obtained by contacting the issuer, analysts, or the appropriate stock
     exchange (for exchange-traded securities), analysis of the issuer's
     financial statements or other available documents and, if necessary,
     available information concerning other securities in similar circumstances.

     Most foreign markets close before the New York Stock Exchange (NYSE).
     Occasionally, developments that could affect the closing prices of
     securities and other assets may occur between the times at which valuations
     of such securities are determined (that is, close of the foreign market on
     which the securities trade) and the close of business on the NYSE. If these
     developments are expected to materially affect the value of the securities,
     the valuations may be adjusted to reflect the estimated fair value as of
     the close of the NYSE, as determined in good faith under procedures
     established by the Board of Directors.

 2.  REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements under
     which the Fund lends excess cash and takes possession of securities with an
     agreement that the counterparty will repurchase such securities. In
     connection with transactions in repurchase agreements, a bank as custodian
     for the Fund takes possession of the underlying securities (collateral),
     with a market value at least equal to the amount of the repurchase
     transaction, including principal and accrued interest. To the extent that
     any repurchase transaction exceeds one business day, the value of the
     collateral is marked-to-market on a daily basis to determine the adequacy
     of the collateral. In the event of default on the obligation to repurchase,
     the Fund has the right to liquidate the collateral and apply the proceeds
     in satisfaction of the obligation. In the event of default or bankruptcy by
     the counter-party to the agreement, realization and/or retention of the
     collateral or proceeds may be subject to legal proceedings.

     The Fund, along with other affiliated investment companies, may utilize a
     joint trading account for the purpose of entering into one or more
     repurchase agreements.

 3.  REVERSE REPURCHASE AGREEMENTS: The Fund may enter into reverse repurchase
     agreements with institutions that the Fund's investment adviser has
     determined are creditworthy. Under a reverse repurchase agreement, the Fund
     sells securities and agrees to repurchase them at a mutually agreed upon
     date and price. Reverse repurchase agreements involve the risk that the
     market value of the securities purchased with the proceeds from the sale of
     securities received by the Fund may decline below the price of the
     securities the Fund is obligated to repurchase. Reverse repurchase
     agreements also involve credit risk with the counterparty to the extent
     that the value of securities subject to repurchase exceed the Fund's

                                                                              13

     liability under the reverse repurchase agreement. Securities subject to
     repurchase under reverse repurchase agreements, if any, are designated as
     such in the Statement of Net Assets.

     At June 30, 2004, the Fund had a reverse repurchase agreement outstanding
     with UBS Warburg as follows:

     Weighted  Average Days to Maturity                       11
</Table>

     The weighted average weekly balance of reverse repurchase agreements
     outstanding during the six months ended June 30, 2004 was approximately
     $13,287,000 at a weighted average weekly interest rate of 1.50%.

4.   FOREIGN CURRENCY TRANSLATION: The books and records of the Fund are
     maintained in U.S. dollars. Foreign currency amounts are translated into
     U.S. dollars at the mean of the bid and asked prices of such currencies
     against U.S. dollars last quoted by a major bank as follows:

     -    investments, other assets and liabilities at the prevailing rates of
          exchange on the valuation date;

     -    investment transactions and investment income at the prevailing rates
          of exchange on the dates of such transactions.

     Although the net assets of the Fund are presented at the foreign exchange
     rates and market values at the close of the period, the Fund does not
     isolate that portion of the results of operations arising as a result of
     changes in the foreign exchange rates from the fluctuations arising from
     changes in the market prices of the securities held at period end.
     Similarly, the Fund does not isolate the effect of changes in foreign
     exchange rates from the fluctuations arising from changes in the market
     prices of securities sold during the period. Accordingly, realized and
     unrealized foreign currency gains (losses) due to securities transactions
     are included in the reported net realized and unrealized gains (losses) on
     investment transactions and balances.

     Net realized gains (losses) on foreign currency transactions represent net
     foreign exchange gains (losses) from sales and maturities of foreign
     currency exchange contracts, disposition of foreign currencies, currency
     gains or losses realized between the trade and settlement dates on
     securities transactions, and the difference between the amount of
     investment income and foreign withholding taxes recorded on the Fund's
     books and the U.S. dollar equivalent amounts actually received or paid. Net
     unrealized currency gains (losses) from valuing foreign currency
     denominated assets and liabilities at period end exchange rates are
     reflected as a component of unrealized appreciation (depreciation) on
     investments and foreign currency translations in the Statement of Net
     Assets. The change in net unrealized currency gains (losses) on foreign
     currency translations for the period is reflected in the Statement of
     Operations.

     Foreign security and currency transactions may involve certain
     considerations and risks not typically associated with those of U.S. dollar
     denominated transactions as a result of, among other factors, the
     possibility of lower levels of governmental supervision and regulation of
     foreign securities markets and the possibility of political or economic
     instability.

The Fund may use derivatives to achieve its investment objectives. The Fund may
engage in transactions in futures contracts on foreign currencies, stock
indices, as well as in options, swaps and structured notes. Consistent with the
Fund's investment objectives and policies, the Fund may use derivatives for
non-hedging as well as hedging purposes.

Following is a description of derivative instruments that the Fund have utilized
and their associated risks:

5.   FOREIGN CURRENCY EXCHANGE CONTRACTS: The Fund may enter into foreign
     currency exchange contracts generally to attempt to protect securities and
     related receivables and payables against changes in future foreign exchange
     rates and, in certain situations, to gain exposure to a foreign currency. A
     foreign currency exchange contract is an agreement between two parties to
     buy or sell currency at a set price on a future date. The market value of
     the contract will fluctuate with changes in currency exchange rates. The
     contract is marked-to-market daily and the change in market value is
     recorded by the Fund as unrealized gain or loss. The Fund records realized
     gains or losses when the contract is closed 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. Risk may arise upon entering into these contracts from
     the potential inability of counter parties to meet the terms of their
     contracts and is generally limited to the amount of unrealized gain on the
     contracts, if any, at the date of default. Risks may also arise from
     unanticipated movements in the value of a foreign currency relative to the
     U.S. dollar.

6.   STRUCTURED SECURITIES: The Fund may invest in interests in entities
     organized and operated solely for the purpose of

                                            MORGAN STANLEY HIGH YIELD FUND, INC.

NOTES TO FINANCIAL STATEMENTS (CONT'D)      June 30, 2004 (Unaudited)

     restructuring the investment characteristics of sovereign debt obligations.
     This type of restructuring involves the deposit with or purchase by an
     entity of specified instruments and the issuance by that entity of one or
     more classes of securities ("Structured Securities") backed by, or
     representing interests in, the underlying instruments. Structured
     Securities generally will expose the Fund to credit risks of the underlying
     instruments as well as of the issuer of the Structured Security. Structured
     Securities are typically sold in private placement transactions with no
     active trading market. Investments in Structured Securities may be more
     volatile than their underlying instruments, however, any loss is limited to
     the amount of the original investment.

7.   FUTURES: The Fund may purchase and sell futures contracts. Futures
     contracts provide for the sale by one party and purchase by another party
     of a specified amount of a specified security, index, instrument or basket
     of instruments. Futures contracts (secured by cash or government securities
     deposited with brokers or custodians as "initial margin") are valued based
     upon their quoted daily settlement prices; changes in initial settlement
     value (represented by cash paid to or received from brokers as "variation
     margin") are accounted for as unrealized appreciation (depreciation). When
     futures contracts are closed, the difference between the opening value at
     the date of purchase and the value at closing is recorded as realized gains
     or losses in the Statement of Operations.

     The Fund may use futures contracts in order to manage exposure to the stock
     and bond markets, to hedge against unfavorable changes in the value of
     securities or to remain fully invested and to reduce transaction costs.
     Futures contracts involve market risk in excess of the amounts recognized
     in the Statement of Net Assets. Risks arise from the possible movements in
     security values underlying these instruments. The change in value of
     futures contracts primarily corresponds with the value of their underlying
     instruments, which may not correlate with the change in value of the hedged
     investments. In addition, there is the risk that the Fund may not be able
     to enter into a closing transaction because of an illiquid secondary
     market.

8.   OVER-THE-COUNTER TRADING: Securities and other derivative instruments that
     may be purchased or sold by the Fund may consist of instruments not traded
     on an exchange. The risk of nonperformance by the obligor on such an
     instrument may be greater, and the ease with which the Fund can dispose of
     or enter into closing transactions with respect to such an instrument may
     be less, than in the case of an exchange-traded instrument. In addition,
     significant disparities may exist between bid and asked prices for
     derivative instruments that are not traded on an exchange. Derivative
     instruments not traded on exchanges are also not subject to the same type
     of government regulation as exchange traded instruments, and many of the
     protections afforded to participants in a regulated environment may not be
     available in connection with such transactions.

9.   OTHER: Security transactions are accounted for on the date the securities
     are purchased or sold. Realized gains and losses on the sale of investment
     securities are determined on the specific identified cost basis. Interest
     income is recognized on the accrual basis and discounts and premiums on
     investments purchased are accreted or amortized in accordance with the
     effective yield method over their respective lives, except where collection
     is in doubt. Distributions to stockholders are recorded on the ex-dividend
     date.

B. ADVISER: Morgan Stanley Investment Management Inc. (the "Adviser") provides
investment advisory services to the Fund under the terms of an Investment
Advisory and Management Agreement (the "Agreement"). Under the Agreement, the
Adviser is paid a fee computed weekly and payable monthly at an annual rate of
0.70% of the Fund's average weekly net assets.

C. ADMINISTRATOR: JPMorgan Chase Bank, through its corporate affiliate J.P.
Morgan Investor Services Co. (the "Administrator"), provides administrative
services to the Fund under an Administration Agreement. The Administrator is
paid a fee computed weekly and payable monthly at an annual rate of 0.02435% of
the Fund's average weekly net assets, plus $24,000 per annum. In addition, the
Fund is charged for certain out-of-pocket expenses incurred by the Administrator
on its behalf. An employee of the Administrator is an Officer of the fund.

D. CUSTODIAN: JPMorgan Chase Bank and its affiliates serve as custodian for the
Fund. The Custodian holds cash, securities, and other assets of the Fund as
required by the 1940 Act. Custody fees are payable monthly based on assets held
in custody, investment purchases and sales activity and account maintenance
fees, plus reimbursement for certain out-of-pocket expenses.

E. FEDERAL INCOME TAXES: It is the Fund's intention to continue to qualify as a
regulated investment company and distribute all of its taxable income.
Accordingly, no provision for Federal income taxes is required in the financial
statements. Dividend income and distributions to stockholders are recorded on
the ex-dividend date.

The Fund may be subject to taxes imposed by countries in which it invests. Such
taxes are generally based on income and/or

                                                                              15

capital gains earned or repatriated. Taxes are accrued and applied to net
investment income, net realized gains and net unrealized appreciation as such
income and/or gains are earned.

The tax character of distributions paid may differ from the character of
distributions shown on the Statements of Changes in Net Assets due to short-term
capital gains being treated as ordinary income for tax purposes. The tax
character of distributions paid during 2003 and 2002 were as follows:

<Table>

     2003 DISTRIBUTIONS                2002 DISTRIBUTIONS

     $6,671                   $--        $9,048          $--
</Table>

The amount and character of income and capital gain distributions to be paid by
the Fund are determined in accordance with Federal income tax regulations, which
may differ from accounting principles generally accepted in the United States.
The book/tax differences are considered either temporary or permanent in nature.

Temporary differences are attributable to differing book and tax treatments for
the timing of the recognition of gains and losses on certain investment
transactions and the timing of the deductibility of certain expenses.

Permanent book and tax basis differences may result in reclassifications among
undistributed (distributions in excess of) net investment income (or accumulated
net investment loss), accumulated net realized gain (loss) and paid-in capital.

At December 31, 2003, the components of distributable earnings on a tax basis
were as follows:

<Table>
<Caption>
        UNDISTRIBUTED             UNDISTRIBUTED
       ORDINARY INCOME        LONG-TERM CAPITAL GAIN

            $115                       $--
====================================================
</Table>

At June 30, 2004, the Federal income tax cost basis of securities was
$108,290,000 and, accordingly, net unrealized depreciation for Federal income
tax purposes was $1,392,000 of which $7,153,000 related to appreciated
securities and $8,545,000 related to depreciated securities.

At December 31, 2003, the Fund had a capital loss carryforward for U.S. Federal
income tax purposes of approximately $72,207,000 available to offset future
capital gains of which $1,337,000 will expire on December 31, 2007, $4,197,000
will expire on December 31, 2008, $4,214,000 to expire on December 31, 2009,
$24,375,000 will expire on December 31, 2010 and $38,084,000 will expire on
December 31, 2011.

To the extent that capital loss carryforwards are used to offset any future
capital gains realized during the carryforward period as provided by U.S.
Federal income tax regulations, no capital gains tax liability will be incurred
by the Fund for gains realized and not distributed. To the extent that capital
gains are offset, such gains will not be distributed to the stockholders.

Net capital and currency losses incurred after October 31, and within the
taxable year are deemed to arise on the first business day of the Fund's next
taxable year. For the year ended December 31, 2003, the Fund deferred to January
1, 2004, for U.S. Federal income tax purposes, post-October capital losses of
$3,413,000 and post-October currency losses of $82,000.

F. CONTRACTUAL OBLIGATIONS: The Fund enters into contracts that contain a
variety of indemnifications. The Fund's maximum exposure under these
arrangements is unknown. However, the Fund has not had prior claims or losses
pursuant to these contracts and expects the risk of loss to be remote.

G. OTHER: During the six months ended June 30, 2004, the Fund made purchases and
sales totaling approximately $29,888,000 and $30,405,000, respectively, of
investment securities other than long-term U.S. Government securities and
short-term investments. There were no purchases or sales of long-term U.S.
Government securities.

A substantial portion of the Fund's total investments consist of high yield
securities rated below investment grade. Investments in high-yield securities
are accompanied by a greater degree of credit risk and the risk tends to be more
sensitive to economic conditions than higher-rated securities. These investments
are often traded by one market maker who may also be utilized by the Fund to
provide pricing information used to value such securities. The amounts which
will be realized upon disposition of the securities may differ from the value
reflected on the statement of net assets and the differences could be material.

On June 21, 2004, the Board of Directors declared a distribution of $0.04 per
share, derived from net investment income, payable on July 15, 2004, to
stockholders of record on June 30, 2004.

DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN

     Pursuant to the Dividend Reinvestment and Cash Purchase Plan (the "Plan"),
each stockholder will be deemed to have elected, unless American Stock Transfer
& Trust Company (the "Plan Agent") is otherwise instructed by the stockholder in
writing, to have all distributions automatically reinvested in Fund shares.
Participants in the Plan have the option of making additional voluntary cash
payments to the Plan Agent, annually, in any amount from $100 to $3,000, for
investment in Fund shares.

     Dividend and capital gain distributions will be reinvested on the
reinvestment date in full and fractional shares. If the market price per share
equals or exceeds net asset value per share on the reinvestment date, the Fund
will issue shares to participants at net asset value. If net asset value is less
than 95% of the market price on the reinvestment date, shares will be issued at
95% of the market price. If net asset value exceeds the market price on the
reinvestment date, participants will receive shares valued at market price. The
Fund may purchase shares of its Common Stock in the open market in connection
with dividend reinvestment requirements at the discretion of the Board of
Directors. Should the Fund declare a dividend or capital gain distribution
payable only in cash, the Plan Agent will purchase Fund shares for participants
in the open market as agent for the participants.

     The Plan Agent's fees for the reinvestment of dividends and distributions
will be paid by the Fund. However, each participant's account will be charged a
pro rata share of brokerage commissions incurred on any open market purchases
effected on such participant's behalf. A participant will also pay brokerage
commissions incurred on purchases made by voluntary cash payments. Although
stockholders in the Plan may receive no cash distributions, participation in the
Plan will not relieve participants of any income tax which may be payable on
such dividends or distributions.

     In the case of stockholders, such as banks, brokers or nominees, that hold
shares for others who are the beneficial owners, the Plan Agent will administer
the Plan on the basis of the number of shares certified from time to time by the
stockholder as representing the total amount registered in the stockholder's
name and held for the account of beneficial owners who are participating in the
Plan.

     Stockholders who do not wish to have distributions automatically reinvested
should notify the Plan Agent in writing. There is no penalty for
non-participation or withdrawal from the Plan, and stockholders who have
previously withdrawn from the Plan may rejoin at any time. Requests for
additional information or any correspondence concerning the Plan should be
directed to the Plan Agent at:
