     In the year ending December 31, 1997, the SAFECO Money Market Fund returned
4.93% while the average Money Market returned 4.90%, according to Lipper
Analytical Services. At year end, the Fund's seven-day yield was 4.96%. The
Money Market Fund yields are very attractive compared to the Consumer Price
Index that rose 1.70% for the 12 months ending December 31, 1997.

     Early in 1997, ninety-day commercial paper rates fell from 5.30% to 5.20%
in March, when the Federal Reserve raised short-term interest rates. Since that
time, rates have traded in a range between 5.45% and 5.72%, ending the year at
5.57%. The yield curve (interest rates for various maturities) out to one year
remained flat throughout the period, reflecting the market's view of very little
risk of inflation and very steady rates going forward.

     Recently, I invested in U.S. agency securities, commercial paper issued by
top-tier corporations, bank notes, medium-term notes, certificates of deposit,
taxable municipal bonds and an asset-backed student loan trust, a broad range of
assets to seek the best return for our money market investors. Seven securities
have a rate that floats so investors can benefit from higher yields if short
term rates rise. For example, I added a Merrill Lynch & Co. floating rate note
based on the prime rate. This security has an attractive current rate and should
continue to perform well. Banks are slower to lower their prime rates in a
falling rate environment and quicker to raise rates in a rising rate
environment.

     I extended the seven-day weighted average maturity of the Fund from 36 days
at January 1, 1997, to 83 days at year end. I

accomplished this by adding several pieces of one-year paper with attractive
yields, including Abbey National, a British bank, with a 5.88% yield, and
Bayerische Landesbank, a German bank, with a 5.81% yield.  

     It appears that the Federal Reserve will not raise interest rates in the
next few months as previously thought because inflation has remained low. Oil
prices are down due to greater supplies from OPEC and other countries. The Asian
financial turmoil is expected to reduce demand, keeping prices low. The dollar
has increased in value against Southeast Asian currencies, lowering the cost of
imports. As a result, economists are beginning to think that the next move by
the Fed may be an easing or lowering of interest rates in 1998. The timing is
uncertain. I will continue to keep a longer average maturity to retain
higher-yielding assets in the Fund as long as possible.

                            REPORT FROM THE FUND MANAGER
                         SAFECO TAX-FREE MONEY MARKET FUND
                                 December 31, 1997

     In the year ending December 31, 1997, the SAFECO Tax-Free Money Market Fund
returned 3.12% while the average tax-free fund returned 3.08%, according to
Lipper Analytical Services. The Fund began 1997 with a seven-day weighted
average yield of 3.27% andended it at 3.44%.

     Nineteen ninety-seven was a great year for fixed-income securities. A
"great year" in the bond market means that yields decline as bond prices rise.
For longer-maturity municipal bonds, yields dropped by more than half a percent
in 1997. However, rates for tax-free money market funds stayed fairly stable
during the year, fluctuating higher and lower, but showing no strong downward
movement. So what does this indicate? That there is investor resistance to lower
rates? That tax-exempt money market rates are driven largely by factors other
than general interest rate movements, such as supply and demand considerations?
That the yield curve (the difference between long and short-term rates) has
flattened? How about all of the above?

     The important thing to remember about money markets is that it doesn't
really matter what happens in the other fixed-income markets or the equity
markets. And it doesn't really matter what happens in money markets relative to
these other markets. We don't invest in money market funds in order to "make a
killing." We invest in them in order to have some money set aside for expenses
we will have in the short term, and also some emergency funds. We want to get as
much yield as we can, while maintaining quality and liquidity.

     It is the SAFECO Tax-Free Money Market Fund's goal to provide this quality
and liquidity,

<PAGE>

- --------------------------------------------------------------------------------

along with a very competitive yield which is exempt from federal income tax.
During 1997, the Fund performed well, ranking 40th out of 136 comparable funds
for the year, according to Lipper Analytical Services. We continue to use our
barbell strategy, with a heavy weighting of the Fund's assets in short
maturities, and a lesser weighting in longer ones. This structure enables us to
take advantage of periodic upticks in interest rates, locking in higher yields
for longer periods of time for a portion of the Fund's assets.

     For 1998, we plan to manage the SAFECO Tax-Free Money Market Fund as we
have in the past -- providing quality, liquidity, and a competitive, tax-exempt
yield.

                           NOTES TO FINANCIAL STATEMENTS

1.   GENERAL

     The SAFECO Money Market Trust ("Trust") is registered under the Investment
Company Act of 1940, as amended, as a diversified, open-end management
investment company. The Trust consists of the SAFECO Money Market Fund and
SAFECO Tax-Free Money Market Fund (together the "Funds").  

     Effective September 30, 1996, the Money Market Fund began issuing two new
classes of shares--Class A and Class B shares. These new shares are distributed
by financial professionals and, like the no-load class, have no associated sales
or distribution charges.

2.   SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of significant accounting policies consistently
followed by each Fund in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles which
permit management to make certain estimates and assumptions at the date of the
financial statements.

     SECURITY VALUATION.  Investments consist of short-term securities maturing
within thirteen months from the date of purchase. Securities in the Tax-Free
Money Market Fund with maturities of more than thirteen months have floating
rates and/or demand features which qualify them as short-term securities.
Securities purchased at par are valued at cost. All other securities are valued
at amortized cost, which approximates  market value.

     SECURITY TRANSACTIONS.  Security transactions are recorded on the trade
date. The cost of each portfolio is the same for financial statement  and
federal income tax purposes.

     SECURITIES PURCHASED ON A WHEN-ISSUED BASIS.  In the Tax-Free Money Market
Fund, securities purchased on a when-issued or delayed basis may be settled a
month or more after the trade date. The securities purchased are carried in the
portfolio at market and are subject to market  fluctuation during this period.
These securities begin earning interest on the settlement date. As commitments
to purchase when-issued securities become fixed, the Tax-Free Money Market Fund
segregates liquid assets in an amount equal to the total obligation.


                                       - 16 -

- --------------------------------------------------------------------------------

     INCOME RECOGNITION.  Interest is accrued on portfolio investments daily.
Bond premiums, original issue discounts and market discounts are amortized to
either call or maturity dates.              

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Net investment income is
declared as a dividend to shareholders of record as of the close of  each
business day and payment is made as of the last business day of each month.

     FEDERAL INCOME AND EXCISE TAXES.  Each Fund intends to continue to comply
with the requirements of the Internal Revenue Code applicable  to regulated
investment companies by distributing substantially all income to shareholders in
a manner which results in no tax to the Fund. Therefore, no federal income or
excise tax provision is required. The Tax-Free Money Market Fund intends to
satisfy conditions which will enable  it to designate its dividends from net
investment income as tax-exempt dividend distributions.

3.   INVESTMENT ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

     SAFECO Asset Management Company receives investment advisory fees from the
Funds. For the Money Market Fund, the fee is based on average daily net assets
at the annual rate of 50/100 of one percent on the first $250 million, declining
in three levels to 25/100 of one percent on net assets over $750 million. For
the Tax-Free Money Market Fund, the fee is based on average daily net assets at
the annual rate of 50/100 of one percent on the first $100 million, declining in
three levels to 20/100 of one percent on net assets over $500 million. SAFECO
Services  Corporation receives shareholder servicing fees.

     NOTES PAYABLE AND INTEREST EXPENSE. The Funds may borrow money for
temporary purposes from SAFECO Corporation or its affiliates. Interest rates
equivalent to commercial bank interest rates are charged on loans over $100,000.
No interest is charged on loans under $100,000.  

     LINE OF CREDIT. The Trust, together with all other management investment
companies for which SAFECO Asset Management Company serves as investment
advisor, has a line of credit arrangement with certain financial institutions.
Under these arrangements, $75 million is available to meet short-term finanicing
needs. No balance was outstanding under these arrangements at December 31, 1997.

                         REPORT OF ERNST & YOUNG LLP,
                             INDEPENDENT AUDITORS


TO THE BOARD OF TRUSTEES AND SHAREHOLDERS
OF THE SAFECO MONEY MARKET TRUST

     We have audited the accompanying statements of assets and liabilities,
including the portfolios of investments, of the SAFECO Money Market Trust
(comprising, respectively, the SAFECO Money Market Fund and SAFECO Tax-Free
Money Market Fund) as of December 31, 1997, and the related statements of
operations, the statements of changes in net assets, and the financial
highlights for each of the periods indicated therein. 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 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 securities owned as of
December 31, 1997, by correspondence with the custodian. 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, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
each of the respective funds constituting the SAFECO Money Market Trust at
December 31, 1997, the results of their operations, the changes in their net
assets, and the financial highlights for each of the periods indicated therein,
in conformity with generally accepted accounting principles.
