THE TURKISH INVESTMENT FUND, INC.

Overview


LETTER TO STOCKHOLDERS

For the six months ended April 30, 2003, The Turkish Investment Fund, Inc. (the
"Fund") had a total return, based on net asset value per share, of 18.04%
compared to 17.69% for the U.S. dollar adjusted Morgan Stanley Capital
International (MSCI) Turkey Index (the "Index"). On April 30, 2003, the closing
price of the Fund's shares on the New York Stock Exchange was $4.46,
representing a 13.7% discount to the Fund's net asset value per share.

MARKET REVIEW

During the six months ending April 30, 2003, Turkey was among the most volatile
global markets, falling as much as 24.7% (Index return) in March before
rebounding in April and eventually returning 17.7%. During this period the
market fell and rebounded more than 25% on two occasions.

In November 2002, after under-performing for most of the year, the market surged
+41.7% following November 3rd elections making it the best performing global
equity market during the month. The equity market rebounded due to prospects
that the winning party, the Pro-Islamic Justice and Development Party (AKP),
would live up to campaign vows to support European Union (EU) reforms and the
economic stabilization program backed by a $16 billion dollar loan from the
International Monetary Fund (IMF). The AKP won nearly two thirds of the seats in
parliament allowing for the formation of a single party government after years
of fractious and unstable coalition governments. In December, however, overall
performance was muted due to the EU council's decision to start accession
negotiations late in 2004 on concerns over the crisis in Iraq. During March,
Turkey, which was the market most negatively affected by the U.S. led war in
Iraq, benefited in April from a surge in domestic sentiment. This surge in
sentiment was a result of policy decisions by the IMF (a disbursement of $700
million dollars in loans) and the Central Bank lowering rates. Prospects that
Turkish construction companies will share in the reconstruction of Iraq, coupled
with lower global oil prices and an improved outlook for tourism has only helped
sentiment. Despite uncertainties over global growth and geo-political concerns
in the Middle East, so far the period under review has proved to be a positive
one for Turkish equities as the market has managed to return +17.4% year-to-date
on the back of a strong +33.6% return month-to-date in April of 2003.

Overall stock selection was the primary driver to the Fund's out-performance
while sector allocation remains mixed. The strongest contribution to relative
performance came from stock selection within sectors such as industrials and
consumer discretionary. Stock selection within financials detracted from
performance; however the impact to performance was mitigated due to our
underweight in the sector relative to the Index. Sector allocations to consumer
staples and industrials were the only other significant detractors during the
period in review.

We remain constructive on the country given falling interest rates as inflation
remains in check and the government advances its privatization efforts. Gross
domestic product growth in 2003-4 is expected to average 5.6%, driven by lower
real interest rates as well as a pick-up in private investment and consumption.
In our opinion, Turkey continues to trade at attractive valuations and is likely
to be a net benefactor from post-war Iraq reconstruction efforts and as a result
we remain overweight industrials and export-oriented stocks. We maintain an
underweight in financials as we remain cautious on Turkey's daunting debt
profile and high real rates. With the political backdrop still a risk, and with
U.S.-Turkey relations under strain we will closely monitor for any slippage on
the IMF program, fiscal policy and resurgence in tensions between the government
and the military.

Sincerely,




Ronald E. Robison

                                               THE TURKISH INVESTMENT FUND, INC.

NOTES TO FINANCIAL STATEMENTS                  April 30, 2003 (unaudited)


     The Turkish Investment Fund, Inc. (the "Fund") was incorporated in Maryland
on September 27, 1988 and is registered as a non-diversified, closed-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is long-term capital appreciation
through investments primarily in equity securities of Turkish corporations.

A.   ACCOUNTING POLICIES: The following significant accounting policies are in
conformity with accounting principles generally accepted in the United States of
America for investment companies. Such policies are consistently followed by the
Fund in the preparation of its financial statements. Accounting principles
generally accepted in the United States of America 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: In valuing the Fund's assets, all listed securities,
     for which market quotations are readily available are valued at the last
     sales price on the valuation date, or if there was no sale on such date at
     the mean between the current bid and asked prices. Securities which are
     traded over-the-counter are valued at the mean of current bid and asked
     prices obtained from reputable brokers. Short-term securities which mature
     in 60 days or less are valued at amortized cost. For all other securities
     and investments for which market values are not readily available,
     including restricted securities, and where prices determined in accordance
     with aforementioned procedures are not reflective of fair market value,
     values are determined in good faith, under fair valuation procedures
     adopted by the Board of Directors, although actual calculations may be done
     by others.

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 counterparty to the agreement, realization and/or retention of the
     collateral or proceeds may be subject to legal proceedings.

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

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

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

     Although the net assets of the Fund are presented at the foreign exchange
     rate 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 rate 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 the foreign
     exchange rate 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 currency, 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.

                                       6
<Page>

     A significant portion of the Fund's net assets consists of equity
     securities denominated in Turkish lira. Changes in currency exchange rates
     will affect the value of and investment income from securities. Turkish
     securities are often subject to greater price volatility, limited
     capitalization and liquidity, and higher rates of inflation than securities
     of companies based in the United States. In addition, Turkish securities
     may be subject to substantial governmental involvement in the economy and
     greater social, economic and political uncertainty.

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 has utilized
and their associated risks:

4.   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 counterparties 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.

5.   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. Dividend income is recorded on
     the ex-dividend date (except certain dividends which may be recorded as
     soon as the Fund is informed of such dividends) net of applicable
     withholding taxes.

B.   ADVISERS: Morgan Stanley Investment Management Inc. and Morgan Stanley
Investment Management Limited (the "Advisers") provide investment advisory
services to the Fund under the terms of an Investment Advisory Agreement (the
"Agreement"). Under the Agreement, advisory fees are computed weekly and payable
monthly at an annual rate of 0.95% of the Fund's first $50 million of average
weekly net assets, 0.75% of the next $50 million of average weekly net assets
and 0.55% of average weekly net assets in excess of $100 million.

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.

D.   CUSTODIAN: JPMorgan Chase Bank serves as custodian for the Fund. Custody
fees are payable monthly based on assets held in custody, investment purchase
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 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 2002 and 2001 were as follows:

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 of
America. 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 differences may result in reclassifications among undistributed net
investment income (loss), accumulated net realized gain (loss) and paid-in
capital. Adjustments for permanent book-tax differences, if any, are not
reflected in ending undistributed net investment income (loss) for the purpose
of calculating net investment income (loss) per share in the financial
highlights.

At April 30, 2003, the U.S. Federal income tax cost basis of investments
(excluding foreign currency if applicable) was $26,613,000 and, accordingly, net
unrealized appreciation for U.S. Federal income tax purposes was $2,589,000, of
which $3,907,000 related to appreciated securities and $1,318,000 related to
depreciated securities.

At October 31, 2002, the Fund had a capital loss carryforward for U.S. Federal
income tax purposes of approximately $40,595,000 available to offset future
capital gains of which $15,443,000 will expire on October 31, 2009 and
$25,152,000 to expire on October 31, 2010. To the extent that capital gains are
offset, such gains will not be distributed to the stockholders.

F.   OTHER: During the six months ended April 30, 2003, the Fund made purchases
and sales totaling $27,230,000 and $26,875,000, 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.

Each Director of the Fund who is not an officer of the Fund or an affiliated
person as defined under the Investment Company Act of 1940, as amended, may
elect to participate in the Directors' Deferred Compensation Plan (the
"Compensation Plan"). Under the Compensation Plan, such Directors may elect
to defer payment of a percentage of their total fees earned as a Director of
the Fund. These deferred portions will be treated, based on an election by
the Director, as if they were either invested in the Fund's shares or
invested in U.S. Treasury Bills, as defined under the Compensation Plan. At
April 30, 2003, the deferred fees payable under the Compensation Plan totaled
$17,000 and are included in Directors' Fees and Expenses on the Statement of
Net Assets. The deferred portion of Directors' Fees and Expenses shown on the
Statement of Operations is impacted by fluctuations in the market value of
the investments selected by each Director. For the six months ended April 30,
2003, Other Expenses were reduced by approximately $3,000 due to these
fluctuations.

During the six months ended April 30, 2003, the Fund incurred $35,000 of
brokerage commissions with Morgan Stanley & Co., Incorporated, an affiliate of
the Advisers.

On September 15, 1998, the Fund commenced a share repurchase program for
purposes of enhancing stockholder value and reducing the discount at which the
Fund's shares trade from their net asset value. For the six months ended April
30, 2003, the Fund did not repurchase shares. From the inception of the program
through April 30, 2003, the Fund has repurchased 1,396,709 of its shares at an
average discount of 17.31% from net asset value per share. The Fund expects to
continue to repurchase its outstanding shares at such time and in such amounts
as it believes will further the accomplishment of the foregoing objectives,
subject to review by the Board of Directors.

G.   SUBSEQUENT EVENT: The Annual Meeting of the Stockholders of the Fund was
held on June 5, 2003. The following is a summary of the proposal presented and

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:
