FROM THE CHAIRMAN
     State Street Research

After putting on a spectacular show of strength in the second quarter of 2003,
the U.S. economy settled down to a slower, but nevertheless solid, pace of
growth during the six-month period from November 1, 2003, to April 30, 2004.
Gross Domestic Product (GDP), a common measure of economic growth, rose 4.1% in
the fourth quarter of 2003 and 4.2% for the first quarter of 2004. Consumer
confidence was generally strong throughout the period as a combination of
accelerated tax cuts and tax rebates fueled higher disposable income for most
working Americans. The housing market was strong, and consumer spending
continued to rise. Better yet, business spending began to recover after a long
period of stagnation. Corporate profits staged a solid rebound, making it easier
for companies to increase outlays, especially on information technology and
electronic equipment.

The economic news was slightly less upbeat as the first quarter of 2004 began.
Durable goods orders declined and the number of new jobs added to the labor
market in January and February fell short of expectations. Consumer confidence
slipped in March. However, strong job growth in March and April suggested that
the economic recovery was on solid ground. The period ended with the expectation
that the Federal Reserve Board would likely raise short-term interest rates
sooner rather than later in the year.

Stock and Bond Markets Moved Higher
The stock market moved sharply higher through early February as economic growth
firmed up and corporate profits rose 20% or more for the reporting period, as
reported by Thomson First Call. However, a host of worries stopped the major
indexes in their tracks in the final six weeks of the period. Investors grew
more cautious about interest rates, the threat of terrorist attacks and
corporate profit comparisons going forward.

High-yield bonds continued to rally, delivering returns that exceeded those of
the broad stock market. However, they also stalled along with the stock market
late in the period. Most other segments of the bond market reported low
single-digit returns. Mortgage bonds bounced back as prepayment activity slowed.
Investment-grade and municipal bonds earned solid but modest returns. Government
bonds were the period's weakest performers; they were hurt the most when
interest rates rose late in the period.

Looking Ahead
The recent bear and bull cycles serve as a reminder that markets can be
unpredictable, which underscores the importance of having an asset allocation
plan in place. If you have a plan in place, stay with it, invest regularly and
talk to your investment professional before you make a significant move outside
your plan.

As always, we look forward to helping you achieve your long-term financial goals
with State Street Research Funds.

Sincerely,

/s/ RICHARD S. DAVIS

PERFORMANCE

          Discussion as of April 30, 2004

How State Street Research Government Income Fund Performed
State Street Research Government Income Fund returned 0.29% for the six-month
period ended April 30, 2004.(1) The fund trailed both the Merrill Lynch
Government Master Index, which returned 0.80%, and the Lipper General U.S.
Government Funds Average, which returned 0.56% over the same period.(2)

Reasons for the Fund's Performance
Interest rates remained volatile over the six-month reporting period. From
November 2003 through March 2004, as employment growth appeared to be weak,
interest rates gradually fell. However, interest rates spiked dramatically
higher as improved payroll data was reported for both March and April. In this
environment, the fund's decision to underweight government agency issues
detracted from its return because agency bonds performed better than Treasuries.

The fund's exposure to mortgage-backed securities (MBS) benefited performance
during the first five months of the period. However, much of this gain was
offset in April as the mortgage sector underperformed Treasuries amid sharply
rising interest rates. The fund's investment in commercial mortgage-backed
securities (CMBS) helped performance as the sector beat Treasuries. Security
selection among CMBS was also a positive factor.

The fund's shorter-than-benchmark duration was a slight positive for the
six-month period. Initially, the fund's shorter duration hampered returns as
interest rates fell. However, these losses were more than offset when interest
rates rose in April. Duration is a measure of interest-rate sensitivity. Our
decision to shorten duration in anticipation of higher interest rates proved
favorable when interest rates did move higher over the period.

Looking Ahead
The fixed income markets have signaled that they expect inflation to move higher
and the Federal Reserve Board to respond with higher short-term interest rates.
With that in mind, we plan to maintain the fund's shorter-than-benchmark
duration in order to reduce interest-rate risk. We also expect to stay
underweight in government agencies, which we believe could suffer from potential
legislative changes and headline risks. In April, we began adding to our stake
in mortgages, which look more attractive on a risk/return basis after the recent
rise in interest rates. We also plan to maintain the fund's modest exposure to
CMBS, paying close attention to the credit risk of specific issues because the
prospects for commercial real estate are less certain.

A Word about Risk
The major risks of bond investing include the tendency for bond prices to fall
when interest rates rise. Although the U.S. government ensures the timely
payment of principal and interest on certain underlying securities, the value of
fund shares is not guaranteed and will fluctuate.

Because financial markets and mutual fund strategies are constantly evolving, it
is possible that the fund's holdings, market stance, outlook for various
industries or securities and other matters discussed in this report have changed
since this information was prepared. Portfolio changes should not be considered
recommendations for action by individual investors.

(1)  Class A shares; does not reflect sales charge.

(2)  The Merrill Lynch Government Master Index is comprised of fixed-rate U.S.
     Treasury and agency securities. The index is unmanaged and does not take
     transaction charges into consideration. It is not possible to invest
     directly in an index. The Lipper General U.S. Government Funds Average
     shows the performance of a category of mutual funds with similar goals. The
     Lipper average shows you how well the fund has done compared with competing
     funds.

(3)  Keep in mind that the performance data quoted represents past performance
     and is no guarantee of future results. Current performance may be lower or
     higher than the performance data quoted herein. For the most recent
     month-end performance results, visit our website at www.ssrfunds.com. The
     fund's share price, yield and return will fluctuate, and you may have a
     gain or loss when you sell your shares. All returns assume reinvestment of
     capital gains distributions and income dividends at net asset value. The
     returns shown do not reflect the deduction of taxes that a shareholder
     would pay on fund distributions or the redemption of fund shares.

(4)  Performance reflects a maximum 4.50% Class A share front-end sales charge,
     or a 5% Class B or Class B(1), or 1% Class C share contingent deferred
     sales charge, where applicable.

(5)  Performance for Class B(1) shares reflects Class B share performance
     through December 31, 1998, and Class B(1) share performance thereafter.
     Performance for Class R shares reflects Class A share performance through
     April 2, 2003, and Class R share performance thereafter. If the returns for
     Class B(1) and Class R shares had reflected their current
     service/distribution (Rule 12b-1) fees for the entire period, these returns
     would have been lower.

(6)  Class R and Class S shares, offered without sales charge, are only
     available through certain employee benefit plans and special programs.

Notes to Unaudited Financial Statements

April 30, 2004

Note 1
State Street Research Government Income Fund is a series of State Street
Research Financial Trust (the "Trust"), which is organized as a Massachusetts
business trust registered under the Investment Company Act of 1940, as amended,
as an open-end management investment company.

The investment objective of this fund is to seek high current income. Under
normal market conditions, the fund invests at least 80% of net assets in U.S.
government securities.

The fund offers six classes of shares. Class A shares are subject to an initial
sales charge of up to 4.50% and pay annual service and distribution fees equal
to 0.30% of average daily net assets. Class B(1) shares pay annual service and
distribution fees equal to 1.00% of average daily net assets and automatically
convert into Class A shares (which pay lower ongoing expenses) at the end of
eight years. Class B(1) shares are subject to contingent deferred sales charge
on certain redemptions made within six years of purchase. Class B shares are
offered only to current shareholders through reinvestment of dividends and
distributions or through exchanges from existing Class B accounts of State
Street Research funds. Class B shares automatically convert into Class A shares
at the end of eight years. Class B shares are subject to a contingent deferred
sales charge on certain redemptions made within five years of purchase. Class C
shares are subject to a contingent deferred sales charge of 1.00% on any shares
redeemed within one year of purchase. Class C shares also pay annual service and
distribution fees equal to 1.00% of average daily net assets. Class R shares are
offered to retirement plans participating in certain platforms sponsored by
broker-dealers which may involve multiple fund families. Class R shares pay a
service and distribution fee of 0.50%. No sales charge is imposed at the time of
purchase or redemption of Class R shares. Class S shares are only offered
through certain retirement accounts, advisory accounts of State Street Research
& Management Company (the "Adviser"), an investment management subsidiary of
MetLife, Inc. ("MetLife"), and special programs. No sales charge is imposed at
the time of purchase or redemption of Class S shares. Class S shares do not pay
any service or distribution fees. The fund's expenses are borne prorata by each
class, except that each class bears expenses, and has exclusive voting rights
with respect to provisions of the plans of distribution, related specifically to
that class. The Trustees declare separate dividends on each class of shares.

The following significant accounting policies are consistently followed by the
fund in preparing its financial statements, and such policies are in conformity
with accounting principles generally accepted in the United States of America.

A. Investment Valuation
Securities are valued by a pricing service, which utilizes market transactions,
quotations from dealers, and various relationships among securities in
determining value. Securities for which there is no such valuation, if any, are
valued at their fair value as determined in accordance with established methods
consistently applied. Short-term securities maturing within sixty days are
valued at amortized cost. Securities quoted in foreign currencies are translated
into U.S. dollars at the current exchange rate.

B. Foreign Currencies
Securities quoted in foreign currencies are translated into U.S. dollars at the
current exchange rate. Gains and losses that arise from changes in exchange
rates are not segregated from gains and losses that arise from changes in market
prices of investments.

C. Security Transactions
Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). Realized gains or losses are reported on the basis of
identified cost of securities delivered. As part of the custodian contract
between the custodian bank and the fund, the custodian bank has a lien on the
securities of the fund to the extent permitted by the fund's investment
restriction to cover any advances made by the

Notes (continued)

custodian bank for the settlement of securities purchased by the fund. At April
30, 2003, the payable to the custodian bank of $95,333 represents the amount due
for cash advance for the settlement of a security purchased.

D. Net Investment Income
Net investment income is determined daily and consists of interest accrued and
discount earned, less the estimated daily expenses of the fund. The fund is
charged for expenses directly attributable to it, while indirect expenses are
allocated among both funds in the Trust.

E. Dividends
Dividends from net investment income are declared daily and paid or reinvested
monthly. Net realized capital gains, if any, are distributed annually, unless
additional distributions are required for compliance with applicable tax
regulations.

Income dividends and capital gains distributions are determined in accordance
with federal income tax regulations which may differ from accounting principles
generally accepted in the United States of America. The difference is primarily
caused by differing treatment of accrued interest on defaulted bonds and premium
amortization on fixed income securities.

F. Federal Income Taxes
No provision for federal income taxes is necessary because the fund has elected
to qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains,
within the prescribed time periods.

At October 31, 2003, the fund had a capital loss carryforward of $10,078,466
available, to the extent provided in regulations, to offset future capital
gains, if any, of which, $492,884, $7,218,002, and $2,367,580 expire on October
31, 2007, 2008 and 2010, respectively.

G. Estimates
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of income and expenses during
the reporting period. Actual results could differ from these estimates.

H. Securities Lending
The fund may seek additional income by lending portfolio securities to qualified
institutions. The fund will receive cash or securities as collateral in an
amount equal to at least 100% of the current market value of any loaned
securities plus accrued interest. By reinvesting any cash collateral it receives
in these transactions, the fund could realize additional gains and losses. If
the borrower fails to return the securities and the value of the collateral has
declined during the term of the loan, the fund will bear the loss. At April 30,
2004, the value of the securities loaned and the value of collateral were
$138,314,173 and $140,979,392 (consisting entirely of cash collateral invested
in State Street Navigator Securities Lending Prime Portfolio), respectively.
During the six months ended April 30, 2004, income from securities lending
amounted to $42,597 and is included in interest income.

I. Futures
The fund may enter into futures contracts as a hedge against unfavorable market
conditions and to enhance income. The fund will not purchase any futures
contract if, after such purchase, more than one-third of net assets would be
represented by long future contracts. The fund will limit its risks by entering
into a futures position only if it appears to be a liquid investment.

Upon entering into a futures contract, the fund deposits with the selling broker
sufficient cash or U.S. government securities to meet the minimum "initial
margin" requirements. Thereafter, the fund receives from or pays to the broker
cash or U.S. government securities equal to the daily fluctuation in value of
the contract ("variation margin"), which is recorded as unrealized gain or loss.
When the contract is closed, the fund records a realized gain or loss equal to
the difference between the value of the contract at the time it has opened and
the value at the time it was closed.

The potential risk to the fund is that the change in value of futures contracts
may not correspond to the change in value of the hedged instruments. In
addition, losses may arise in changes from the value of the underlying
instruments, if there is an illiquid secondary market for the contracts, or if
the counterparty to the contract is unable to perform.

J. Options
The fund may use options to hedge against changes in values of securities the
Portfolio owns or expects to purchase. Writing puts or buying calls tends to
increase the fund's exposure to the underlying instrument and writing calls or
buying puts tends to decrease the fund's exposure to the underlying instrument,
or hedge other fund investments.

For options purchased to hedge the fund's investments, the potential risk to the
fund is that the change in value of options contracts may correspond to the
change in value of the hedged instruments. In addition, losses may arise from
changes in the value of the underlying instruments, if there is an illiquid
secondary market, or if the counter party is unable to perform. The maximum loss
for purchased options is limited to the premium initially paid for the option.
For options written by the fund, the maximum loss is not limited to the premium
initially received for the option.

Note 2
The Trust and the Adviser have entered into an agreement under which the Adviser
earns monthly fees at an annual rate of 0.60% of the first $500 million of net
assets annually, 0.55% of the next $500 million, and 0.50% of any amount over $1
billion. In consideration of these fees, the Adviser furnishes the fund with
management, investment advisory, statistical and research facilities and
services. The Adviser also pays all salaries, rent and certain other expenses of
management. During the six months ended April 30, 2004, the fees pursuant to
such agreement amounted to $1,779,255.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), provides certain shareholder services to the fund such as
responding to inquiries and instructions from investors with respect to the
purchase and redemption of shares of the fund. In addition, MetLife receives a
fee for maintenance of the accounts of certain shareholders who are participants
in sponsored arrangements, such as employee benefit plans, through or under
which shares of the fund may be purchased. Total shareholder service costs are
allocated to each fund in the same ratios as the transfer agent costs. During
the six months ended April 30, 2004, the amount of such expenses allocated to
the fund was $282,917.

The fund has entered into an arrangement with its transfer agent whereby credits
realized as a result of uninvested cash balances were used to reduce a portion
of the fund's expense. During the six months ended April 30, 2004, the fund's
transfer agent fees were reduced by $10,320 under this arrangement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$31,284 during the six months ended April 30, 2004.

The fund has agreed to pay the Adviser for certain administrative costs incurred
in providing other assistance and services to the fund. The fee was based on a
fixed amount that has been allocated equally among the State Street Research
funds. During the six months ended April 30, 2004, the amount of such expenses
was $45,500.

On February 19, 2004, the Distributor entered into an agreement with the NASD
resolving all outstanding issues relating to an investigation by the NASD of the
Distributor's e-mail retention practices and supervision of trading activity in
shares of the State Street Research funds. The Distributor, without admitting or
denying the allegations or the findings set forth in the agreement, and solely
for the purposes of the settlement, agreed to the entry of certain findings by
the NASD relating to the Distributor's compliance with document retention
requirements and the Distributor's supervision of enforcement of shareholder
exchange limitations set forth in the funds' prospectuses. The agreement
contains no allegations or findings of fraudulent conduct by the Distributor. As
part of this agreement, the Distributor made a payment to the fund to compensate
the fund for losses relating to the exchange of fund shares beyond the annual
limit set forth in the fund's prospectus. The payment was allocated among the
fund's share classes as follows: $99,915 to Class A, $24,174 to Class B(1),
$7,801 to Class B, $4,470 to Class C and $2,397 to Class S. These amounts are
shown in the total amount of $138,757 as "Net increase from payment by
affiliate" in the Statement of Operations.

Note 3
For the six months ended April 30, 2004, purchases and sales of securities,
exclusive of short-term obligations, aggregated $1,034,500,362, and
$1,091,651,626 (including $1,027,986,529 and $1,081,279,705 of U.S. government
obligations), respectively.

Note 4
The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plans, the fund pays annual service
fees to the Distributor at a rate of 0.25% of average daily net assets for Class
A, Class B(1), Class B, Class C and Class R shares. In addition, the fund pays
annual distribution fees of 0.05% of average daily net assets for Class A
shares. The fund pays annual distribution fees of 0.75% of average daily net
assets for Class B(1), Class B and Class C shares and 0.25% of average net
assets for Class R shares. The Distributor uses such payments for personal
services and/or the maintenance of shareholder accounts, to reimburse securities
dealers for distribution and marketing services, to furnish ongoing assistance

(f)  Effective November 1, 2001, the fund has adopted the provisions on the
     AICPA Audit and Accounting Guide, Audit of Investment Companies and began
     amortizing premium on all fixed income securities. The effect of this
     change for the year ended October 31, 2002, was to decrease net investment
     income per share by $0.16, increase net realized and unrealized loss per
     share by $0.16, and decrease the ratio of net investment income to average
     net assets by 1.24%. The statement of changes and financial highlights for
     the period prior to November 1, 2001, have not been restated for this

     income per share by $0.16, increase net realized and unrealized loss per
     share by $0.16, and decrease the ratio of net investment income to average
     net assets by 1.24%. The statement of changes and financial highlights for
