LETTER TO SHAREHOLDERS
Dear Shareholders:
An environment of declining interest rates and a favorable outlook for
inflation helped establish a pattern of positive performance in both fixed-
income and equity markets around the world during the past six months. A
series of reductions in short-term interest rates by the Federal Reserve
Board, as well as by several central banks around the world, contributed to
declining yields and rising prices of many fixed-income securities throughout
the period.
For the six months ended December 31, 1995, the Fund posted a total
return of 2.38% (including the reinvestment of distributions). This compares
to a 1.87% return for the Salomon Brothers World Government Bond Index (the
Index), an unmanaged, market-weighted index which includes straight-issue
bonds from the complete universe of 14 government sectors with remaining
maturities of at least one year. Our overweighting in the U.S. dollar bloc and
European bond markets contributed to performance against the Index, while
European currency volatility and our currency weightings within the dollar
bloc detracted from performance.
A pattern of slow to moderate growth and low and controlled inflation
remains a dominant theme in major industrialized countries, including the
United States. While the recent recovery of the dollar against the German mark
and the Japanese yen has added some strength to the economies of Europe and
Japan, the outlook is for sluggish economic growth, in the near term at least.
And although moves by central banks in Germany and Japan to lower interest
rates are intended to stimulate domestic demand, many industrial companies in
these countries are still struggling to compete in a global marketplace in
which their products are less competitively priced. On the positive side, this
does mean little to no inflationary pressure in these countries, and we
believe that this, combined with further reductions in interest rates, could
help provide a foundation for stronger economic growth in the long run.
Inflation in most overseas economies remains in a downward trend, providing
fixed-income investors with opportunities for relatively attractive real
(adjusted for inflation) rates of interest, accompanied by price appreciation.
For next year, we believe that slow U.S. growth, if it continues, could lead
to a cyclical reduction in our borrowing of foreign capital, taking some of
the pressure off the dollar.
The high returns of the U.S. bond market as measured by the Lehman
Brothers Government Bond Index have been echoed in other U.S. dollar-bloc
markets, including those of Australia, New Zealand, and Canada, all of which
saw positive performance over the last 12 months according to Salomon
Brothers. Currently, the Australian market offers significantly higher yields
than the U.S. market and we believe represents good value. As long as the
outlook for U.S. bonds remains positive, these related markets could
outperform the U.S. market.
The majority of our foreign-based holdings remains in Europe. The core
markets, such as Germany and the Netherlands, continue to provide solid
returns against a backdrop of slow growth, low inflation, and declining
official interest rates and remain an important anchor to our foreign
holdings. Other European markets, such as Denmark's, offer a combination of
higher yields with moderate growth and low inflation. The highest yielding
markets have recovered over the last six months, and the Fund has increased
both its bond and currency weightings in these markets. The first part of next
year could be supportive of fixed-income investments, since moderate to slow
growth, with commensurate declines in overall inflation rates, could lead to
further reductions in official interest rates. European governments,
meanwhile, are engaged in multi-year programs to reduce their budget deficits
and debt levels. These programs are positive for bonds, in that lower
government deficits tend to reduce inflationary pressures and lower issuance
of government debt reduces supply pressures on the bond market.
In the Japanese market, powerful deflationary forces have supported a drop
in yields to historically low levels. We now feel this process may be drawing
to an end, given a reversal of priorities at the central bank from fighting
inflation, which is now non-existent, to offsetting the downward spiral of
deflation. Thus, the weighting in Japan, which has been neutral for much of
the past year, will most likely be reduced in the coming year.
We appreciate your support and welcome any questions or comments you may
have.
Respectfully,
/s/ A. Keith Brodkin /s/ Richard O. Hawkins

Note to Shareholders: Effective January 1, 1996, Richard O. Hawkins succeeds

Nanberg will continue in his role as chief fixed income officer, overseeing
the implementation of the overall fixed-income strategy at MFS.

PORTFOLIO MANAGER PROFILE
Richard Hawkins joined MFS in 1988 as a member of the Fixed Income Department.
He is a graduate of Brown University, and received a Masters in Business
Administration degree from the University of Pennsylvania's Wharton School of
Business. He was named Vice President in 1991 and Senior Vice President in
1994. As of January 1, 1996, Mr. Hawkins became director of the International
Fixed Income Department as well as Portfolio Manager of the Fund.
INVESTMENT OBJECTIVE AND POLICIES
The Fund seeks not only preservation, but also growth of capital, together
with moderate current income. Shares of the Fund are purchased at net asset
value. The minimum initial investment is generally $3 million.
The Fund seeks to achieve its objective by investing, under normal market
conditions, at least 80% of its assets in an internationally diversified
portfolio of fixed-income securities. Up to 20% of the Fund's assets may also
be invested in equity securities. Fixed-income securities include bonds,
debentures, mortgage securities, notes, commercial paper, obligations issued
or guaranteed by a government or any of its political subdivisions, agencies
or instrumentalities, and certificates of deposit.
PERFORMANCE SUMMARY
Because mutual funds like MFS Institutional Worldwide Fixed Income Fund are
designed for investors with long-term goals, we have provided cumulative
results as well as the average annual total returns for the applicable time
periods.

All results represent past performance and are not an indication of future
results. Investment return and principal value will fluctuate, and shares,
when redeemed, may be worth more or less than their original cost. All Fund
results reflect the applicable expense subsidy which is explained in the Notes
to Financial Statements. Had the subsidy not been in effect, the results would
have been less favorable.

NOTES TO FINANCIAL STATEMENTS
(1) Business and Organization
MFS Institutional Worldwide Fixed Income Fund (the Fund), formerly known as
the MFS Worldwide Fixed Income Fund, is a non-diversified series of MFS
Institutional Trust (the Trust). The Trust is organized as a Massachusetts
business trust and is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company.
(2) Significant Accounting Policies
Investment Valuations - Debt securities (other than short-term obligations
which mature in 60 days or less), including listed issues and forward
contracts, are valued on the basis of valuations furnished by dealers or by a
pricing service with consideration to factors such as institutional-size
trading in similar groups of securities, yield, quality, coupon rate,
maturity, type of issue, trading characteristics and other market data,
without exclusive reliance upon exchange or over-the-counter prices. Short-
term obligations, which mature in 60 days or less, are valued at amortized
cost, which approximates market value. Non-U.S. dollar denominated short-term
obligations are valued at amortized cost as calculated in the base currency
and translated into U.S. dollars at the closing daily exchange rate. Futures
contracts, options and options on futures contracts listed on commodities
exchanges are valued at closing settlement prices. Over-the-counter options
are valued by brokers through the use of a pricing model which takes into
account closing bond valuations, implied volatility and short-term repurchase
rates. Equity securities listed on securities exchanges or reported through
the NASDAQ system are valued at last sale prices. Unlisted equity securities
or listed equity securities for which last sale prices are not available are
valued at last quoted bid prices. Securities for which there are no such
quotations or valuations are valued at fair value as determined in good faith
by or at the direction of the Trustees.
Foreign Currency Translation - Investment valuations, other assets, and
liabilities initially expressed in foreign currencies are converted each
business day into U.S. dollars based upon current exchange rates. Purchases
and sales of foreign investments, income and expenses are converted into U.S.
dollars based upon currency exchange rates prevailing on the respective dates
of such transactions. Gains and losses attributable to foreign currency
exchange rates on sales of securities are recorded for financial statement
purposes as net realized gains and losses on investments. Gains and losses
attributable to foreign exchange rate movements on income and expenses are
recorded for financial statement purposes as foreign currency transaction
gains and losses. That portion of both realized and unrealized gains and
losses on investments that results from fluctuations in foreign currency
exchange rates is not separately disclosed.
Deferred Organization Expenses - Costs incurred by the Fund in connection with
its organization have been deferred and are being amortized on a straight-line
basis over a five-year period beginning on the date of commencement of
operations of the Fund.
Written Options - The Fund may write covered call or put options for which
premiums are received and are recorded as liabilities, and are subsequently
adjusted to the current value of the options written. Premiums received from
writing options which expire are treated as realized gains. Premiums received
from writing options which are exercised or are closed are offset against the
proceeds or amount paid on the transaction to determine the realized gain or
loss. If a put option is exercised, the premium reduces the cost basis of the
security purchased by the Fund. The Fund, as writer of an option, may have no
control over whether the underlying security may be sold (call) or purchased
(put) and, as a result, bears the market risk of an unfavorable change in the
price of the securities underlying the written option. In general, written
call options may serve as a partial hedge against decreases in value in the
underlying securities or foreign currency to the extent of the premium
received. Written options may also be used as a part of an income producing
strategy reflecting the view of the Fund's management on the direction of
interest or exchange rates.
Forward Foreign Currency Exchange Contracts - The Fund may enter into forward
foreign currency exchange contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the
value of a foreign currency relative to the U.S. dollar. The Fund will enter
into forward contracts for hedging purposes as well as for non-hedging
purposes. For hedging purposes, the Fund may enter into contracts to deliver
or receive foreign currency it will receive from or require for its normal
investment activities. It may also use contracts in a manner intended to
protect foreign currency-denominated securities from declines in value due to
unfavorable exchange rate movements. For non-hedging purposes, the Fund may
enter into contracts with the intent of changing the relative exposure of the
Fund's portfolio of securities to different currencies to take advantage of
anticipated changes. The forward foreign currency exchange contracts are
adjusted by the daily exchange rate of the underlying currency and any gains
or losses are recorded for financial statement purposes as unrealized until
the contract settlement date.
Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and original issue discount are amortized or accreted for financial statement
and tax reporting purposes as required by federal income tax regulations.
Tax Matters and Distributions - The Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided. The Fund files a tax
return annually using tax accounting methods required under provisions of the
Code which may differ from generally accepted accounting principles, the basis
on which these financial statements are prepared. Accordingly, the amount of
net investment income and net realized gain reported on these financial
statements may differ from that reported on the Fund's tax return, and
consequently, the character of distributions to shareholders reported in the
financial highlights may differ from that reported to shareholders on Form
1099-DIV. Foreign taxes have been provided for on interest and dividend income
earned on foreign investments in accordance with the applicable country's tax
rates and to the extent unrecoverable are recorded as a reduction of
investment income. Distributions to shareholders are recorded on the ex-
dividend date.
The Fund distinguishes between distributions on a tax basis and a financial
reporting basis and requires that only distributions in excess of tax basis
earnings and profits are reported in the financial statements as a return of
capital. Differences in the recognition or classification of income between
the financial statements and tax earnings and profits which result in
temporary over-distributions for financial statement purposes, are classified
as distributions in excess of net investment income or accumulated net
realized gains.
(3) Transactions with Affiliates
Investment Adviser - The Fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an effective annual rate
of 0.65% of average daily net assets. The investment adviser did not impose a
portion of its fee, which is reflected as a preliminary reduction of expenses
in the Statement of Operations.
The Fund pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of the Fund, all of whom receive
remuneration for their services to the Fund from MFS. Certain of the officers
and Trustees of the Fund are officers or directors of MFS and MFS Service
Center, Inc. (MFSC).
Shareholder Servicing Agent - MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder servicing agent. The fee is calculated as
a percentage of the average daily net assets at an effective annual rate of
0.0075%.

(6) Financial Instruments
The Fund regularly trades financial instruments with off-balance sheet risk in
the normal course of its investing activities in order to manage exposure to
market risks such as interest rates and foreign currency exchange rates. These
financial instruments include written options, forward foreign currency
exchange contracts and futures contracts.
The notional or contractual amounts of these instruments represent the
investment the Fund has in particular classes of financial instruments and
does not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only
when all related and offsetting transactions are considered. A summary of
obligations under these financial instruments at December 31, 1995, is as
follows:

borrowings up to $350 million, collectively. Borrowings may be made to
temporarily finance the repurchase of Fund shares. Interest is charged to each
fund, based on its borrowings, at a rate equal to the bank's base rate. In
addition, a commitment fee, based on the average daily unused portion of the
line of credit, is allocated among the participating funds at the end of each
quarter. The commitment fee allocated to the Fund for the six months ended
December 31, 1995 was $727.

INDEPENDENT AUDITORS' REPORT
To the Trustees of MFS Institutional Trust and Shareholders of
MFS Institutional Worldwide Fixed Income Fund:
We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of MFS Institutional Worldwide Fixed
Income Fund (one of the series comprising MFS Institutional Trust) as of
December 31, 1995, the related statement of operations for the six months
ended December 31, 1995, the statement of changes in net assets for the six
months then ended and the year ended June 30, 1995, and the financial
highlights for the six months ended December 31, 1995 and for each of the
years in the three year period ended June 30, 1995. These financial statements
and financial highlights are the responsibility of the Fund'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 generally accepted auditing
standards. 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. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of the
securities owned at December 31, 1995 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MFS Institutional
Worldwide Fixed Income Fund at December 31, 1995, the results of its
operations, the changes in its net assets, and its financial highlights for
the respective stated periods in conformity with generally accepted accounting
principles.
