OVERVIEW-MUNICIPAL, INSURED, AND CALIFORNIA FUNDS

    The first half of 1997 was particularly uneventful for the munici-
pal bond markets. As measured by the Bond Buyer 40 Bond Index, long-
term municipal yields stayed within a narrow range, ending the period
slightly lower than where they began. Yields began the period at 5.78%
on January 2, 1997 and ended at 5.69% on June 30, 1997. They ranged
from a high of 6.01% on April 14 to a low of 5.58% on June 20.

    Stable interest rates and contained inflation are the major factors hold-
ing the market in a narrow, quiet range. In fact, falling long-term rates have
caused the yield curve to flatten, diminishing the difference in the yield be-
tween shorter and longer-term bonds.

    Meanwhile, low supply, strong demand (especially from high yield funds)
and price cutting by bond insurers has diminished the differences in yield be-
tween high and low credit quality bonds.

    It's been a difficult market in which to add value. There has been no bad
news to scare people into selling at fire sale prices. And the continued low
supply means there are no big imbalances to take advantage of.

    My techniques of increasing yield--lowering credit quality, giving up call
protection, and extending maturities--have become increasingly difficult to
execute in recent weeks. Quality differentials have narrowed so that a swap
from Aaa to Baa now increases yield only 18 to 20 basis points instead of 25 to
30 as was common several months ago. Flattening of the yield curve (the
difference in yield between various maturities) has reduced the attractiveness
of extending maturities. While the spread between bonds with 10-year calls and
those with six-year calls is still attractive, we have few 10-year-call holdings
that we can use in that kind of swap.

    I think it will take a market correction to reverse the narrowing spreads
in maturity and credit quality. Until that happens my swapping activity will
be low. In the meantime I am going to pursue the possibilities of using more
premium bonds in the Funds to add yield.

    Looking ahead, I don't see a market correction, I see continued stability.
It's hold and clip the coupons time. But really, income and stability are why
people should buy bonds anyway.

SAFECO MUNICIPAL BOND FUND

    The SAFECO Municipal Bond Fund came on strong in the second quarter, to 
return 3.04% for the six months, slightly above the average return of 2.95% for
all general municipal bond funds according to Lipper Analytical Services. For
the 12 months ended June 30, 1997 the Fund was well into the top quartile of
comparable funds with a return of 8.70% compared to the Lipper average of
7.81%.

    The Fund's above average performance was not enough to beat the Lehman
Brothers long municipal bond index which returned 9.73% for the year. But then
it's very difficult for an unleveraged bond fund to outperform an index in a
rising market because the index is a "portfolio on paper" with no cash, no call
features and no transaction expenses.

    Your Fund does best when yields are falling and prices are rising due 
primarily to three factors: Number one, the Fund stays fully invested. Two, it
has a relatively long average maturity. And three, it has a high concentration
of deep discount bonds which perform well in bull markets because of excellent
call protection.

     The performance graph compares a hypothetical $10,000 investment in the 
Fund to a hypothetical investment in a relevant market index.  The index is 
unmanaged and includes no operating expenses or transaction costs.  Past 
performance is not predictive of future results.  Principal value may fluctuate 
so that shares, when redeemed, may be worth more or less than their original 
cost.

                    REPORT FROM THE FUND MANAGER (Continued)

    All of the activity in the Municipal Bond fund centered around one theme:
increase yield. In general, I increased yield by extending maturities and low-
ering credit quality. However, I had one amazing trade in which I picked up
yield, improved credit and extended call protection by selling Puerto Rico
Highway (for a ridiculously high price) and buying Valdez Alaska Marine Termi-
nal.

                         Report from the Fund Manager*
                                 June 30, 1997

SAFECO CALIFORNIA TAX-FREE INCOME FUND

    The California Tax-Free Fund barely beat the Lipper Analytical Services
average for California Funds for the first six months of 1997, returning 2.83%
versus 2.82%. However, for the 12 months it had a very strong 9.20% total re-
turn while the average California fund earned 8.07%. This extra 1.13% put the
SAFECO Fund 11 of 101 funds for the year ended June 30, 1997.

    The Lehman Brothers Long Municipal Bond Index returned 9.73% for the year.
In fact, it's very difficult for an unleveraged bond fund to outperform an index
in a rising market. The index is a "portfolio on paper" with no cash, no call
features and no transaction expenses.

    The California Fund stays fully invested and has an even longer average
maturity and much more aggressive coupon structure than its peers.  For example,
on June 30 the average yield for long municipal bonds was 5.69% while the
average coupon of our portfolio was 5.16%. Because our bonds yield less, they
sell at a discount.  This is an aggressive strategy because discount bonds tend
to be more volatile than bonds that trade at face value. Fortunately

     The performance graph compares a hypothetical $10,000 investment in the 
Fund to a hypothetical investment in a relevant market index.  The index is 
unmanaged and includes no operating expenses or transaction costs.  Past 
performance is not predictive of future results.  Principal value may fluctuate 
so that shares, when redeemed, may be worth more or less than their original 
cost.

                          REPORT FROM THE FUND MANAGER

for us, volatility is two-directional--swings go up as well as down.

    I executed three swaps to increase the yield of the Fund. Selling East Bay
Regional Park District and buying San Bernardino County I was able to pick up
yield and gain call protection. In the other two swaps--out of Eldorado County
Public Agency Finance Authority and California Department of Water Resources
and into University of California Multi Purpose and Los Angeles Convention--I
gained yield by giving up three years of call protection. However, the bonds we
bought were deeply discounted, which goes a long way toward making up for the
nearer calldate.

SAFECO INSURED MUNICIPAL BOND FUND

    The Insured Fund had dramatically better performance than its peer funds
for both the six month and 12-month time periods. The six-month return for the
SAFECO Insured Muni Bond Fund was 2.96%, which ranked the Fund 3 out of 50
funds (whose average was 2.42%). For the year, your Fund returned 8.74% and was
ranked number 2 out of 48 funds (whose average was 7.19%, as reported by Lipper
Analytical Services). The Insured Fund benefited from the same strategies as
the Muni and Cal Funds: being fully invested and favoring discounted bonds.

    The Lehman Brothers Long Insured Index which returned 9.38% for the 12
months ended. In a rising market, it's very difficult for an unleveraged bond
fund to outperform an index because the index is a "portfolio on paper" with no
call features, no cash and no transaction expenses.

    Increasing yield in the Insured Fund is more difficult because I obviously
cannot reduce credit quality to do it. Nevertheless, I picked up 100 basis
points by selling pre-refunded bonds (bonds designated to be prepaid

modest yield gain and two years of call protection.

SAFECO WASHINGTON STATE MUNICIPAL BOND FUND

   In the six-month period and the year ended June 30, 1997, the SAFECO
Washington State Municipal Bond Fund returned 2.68% for the period and
7.51% for the year. Single state bond funds, excluding California and
New York, averaged 7.28% for the year, according to Lipper Analytical
Services, while the Merrill Lynch Long Municipal Bond Index reported
3.56% for the period and 9.73% for the year.

   While the Fund underperformed during the first quarter when rates climbed,
it outperformed competitors (other Washington State municipal bond funds) 
during the second quarter as interest rates fell. This is due to the Funds
longer duration, which gives the Fund greater sensitivity to interest rates.

   During the first quarter, I purchased two issues:

   Washington State general obligation (GO) bonds with 5.25% coupon maturing in
2019 and King County Public Hospital District for Valley Medical Center with a
5.25% coupon and 2015 maturity date. Both of these purchases were rather 
unusual. I generally don't buy GO bonds or shorter maturity bonds (under 20
years) because of their "rich" trading

     *    The Fund's inception was March 18, 1993.  Graph and average annual 
          return comparison begins March 31, 1993.

     The performance graph compares a hypothetical $10,000 investment in the 
Fund to a hypothetical investment in a relevent market index.  The index is 
unmanaged and includes no operating expenses or transaction costs.  Past 
performance is not predictive of future results.  Principal value may fluctuate 
so that shares, when redeemed, may be worth more or less than their original 
cost.

                    REPORT FROM THE FUND MANAGER (Continued)

prices relative to revenue bonds and longer-term bonds. But both of these bonds
appeared to be exceptionally good values.

    I also completed one swap to gain greater call protection for the fund. I
bought Seattle Drain & Wastewater 5.25% of 2025, and sold the same name with a
5.75% coupon of 2022.

    During the second quarter, I bought higher coupon issues such as Renton
General Obligation Bonds 5.75% of 2017 and Seattle Housing Authority Low Income
Housing 6.6% of 2038, yielding 5.85% and 6.2% respectively. Both are insured
and rated AAA.

    Although attractively-priced discount bonds continue to be scarce, I remain
a value investor, buying competitively-priced, long-term bonds with a bias to-
wards discount bonds.

SAFECO INTERMEDIATE-TERM MUNICIPAL BOND FUND

    The SAFECO Intermediate-Term Municipal Bond Fund returned 7.20% for
the year ending June 30, 1997. This compares to an average of 6.55% for
all Intermediate Municipal Debt Funds, as tracked by Lipper Analytical
Services. The Fund's return also exceeds the Lehman Brothers 7-year Mu-
nicipal Bond Index, which showed a return of 7.03% for the twelve-month
period.

    In the six months since our last letter, interest rates have more or less
continued their decline, with the exception of a hiccup from late February
through late April. The value of bonds has correspondingly risen, and the
SAFECO Intermediate-Term Municipal Bond Fund has benefited from this. The Fund
performs well in this type of environment as it has a slightly longer average
maturity than many of its peers (7.5 years on June 30).

    During the quarter we continued our strategy of selling shorter, lower-
yielding bonds and replacing them with longer, higher-yielding ones. We sold
three smaller positions maturing in 2003 and 2004, and added $400,000 par
value of Clark County, Washington PUD maturing in 2007. We

     *    The Fund's inception was March 18, 1993.  Graph and average annual 
          return comparison begins March 31, 1993.

     The performance graph compares a hypothetical $10,000 investment in the 
Fund to a hypothetical investment in a relevent market index.  The index is 
unmanaged and includes no operating expenses or transaction costs.  Past 
performance is not predictive of future results.  Principal value may fluctuate 
so that shares, when redeemed, may be worth more or less than their original 
cost.

                    REPORT FROM THE FUND MANAGER (Continued)

picked up quality as well as yield, as the issue was insured.

    Interest rates have not only fallen in recent months, the relationship
between different points on the yield curve has changed as well. The curve has
flattened, and the spread between a generic seven-year Aa general obligation
bond and its 30-year cousin has narrowed from 94 basis points at the end of
1996 to 81 basis points on June 30. In other words, the reward for extending an
additional 23 years on the yield curve is about 4/5 of a percent.

    Although we certainly cannot predict the future, it seems that there is
some value to be found in the intermediate portion of the tax-exempt market. I
will continue to manage the Fund with an eye to maximizing that value.

                         Notes to Financial Statements

1.  GENERAL
  The SAFECO Tax-Exempt Bond Trust ("Trust") is registered under the Invest-
ment Company Act of 1940, as amended, as a diversified, open-end management
investment company. The Trust consists of the SAFECO Intermediate-Term Munici-
pal Bond Fund (Intermediate), SAFECO Insured Municipal Bond Fund (Insured),
SAFECO Municipal Bond Fund (Municipal), SAFECO California Tax-Free Income Fund
(California) and SAFECO Washington State Municipal Bond Fund (Washington) (to-
gether "the Funds").
  Effective September 30, 1996, the Municipal, California and Washington Funds
began issuing two new classes of shares--Class A and Class B shares (collec-
tively, "Advisor Classes"). Unlike the no-load class of shares (which are sold
directly to the shareholder with no associated sales or distribution charges),
these new classes of shares are sold by financial advisors to shareholders and
have associated sales and distribution charges. Each class of shares repre-
sents an interest in the net assets of the fund.
  In connection with issuing the new Advisor Classes, the Municipal, Califor-
nia and Washington Funds adopted a Plan of Distribution (the "Plan"). Under
the Plan, each Advisor Class pays the distributor, SAFECO Securities Corp.,
for selling its shares at the annual rate of .25% of the average daily net as-
set of the Advisor Class. Class B shares also pay the distributor a distribu-
tion fee at the annual rate of .75% of the average daily net assets of the
Class B shares.
  Under the Plans, the distributor uses the service fees primarily to compen-
sate persons selling Advisor Class shares for providing ongoing services and
the maintenance of shareholder accounts. The distributor uses the distribution
fees primarily to offset the commissions it pays to financial advisors for
selling Class B shares.
 
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 pol-
icies are in conformity with generally accepted accounting principles, which
permits management to make certain estimates and assumptions at the date of
the financial statements.
  SECURITY VALUATION. Tax-exempt bonds are stated on the basis of valuations
provided by a pricing service, which uses information with respect to transac-
tions in bonds, quotations from bond dealers, market transac-

tions in comparable securities and various relationships between securities in
determining value. Short-term investments are valued at cost which approxi-
mates market.
  SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
The cost of the portfolios is the same for financial statement and federal in-
come tax purposes. Realized gains and losses from security transactions are
determined using the identified cost basis.
  SECURITIES PURCHASED ON A WHEN-ISSUED BASIS. 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 sub-
ject to market fluctuation during this period. These securities begin earning
interest on the settlement date. As commitments to purchase when-issued secu-
rities become fixed, the Funds segregate liquid assets in an amount equal to
the total obligation.
  INCOME RECOGNITION. Interest is accrued on portfolio investments daily. Bond
premiums and original issue discounts are amortized to either call or maturity
dates. Market discount on bonds purchased after April 30, 1993 is recorded as
taxable income at disposition.
  DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Net investment income is de-
clared as a dividend to shareholders of record as of the close of each busi-
ness day and payment is made as of the last business day of each month. Net
gains realized from security transactions, if any, will normally be distrib-
uted to shareholders at the end of December.
  FEDERAL INCOME AND EXCISE TAXES. Each Fund intends to comply with the re-
quirements 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 Funds. Therefore, no Federal income or excise
tax provision is required. In addition, the Funds intend to satisfy conditions
which will enable them to pay dividends which, for shareholders, are exempt
from Federal income taxes. Any portion of dividends representing net short-
term capital gains, however, is not exempt and is treated as taxable dividends
for Federal income tax purposes. In addition, income which is derived from am-
ortization on bonds purchased below their issued price after April 30, 1993,
is treated as ordinary income for Federal income tax purposes.
