Merrill Lynch Oregon Municipal Bond Fund Merrill Lynch Multi-State Municipal Series Trust Box 9011 Princeton, NJ 08543-9011 Printed on post-consumer recycled paper Merrill Lynch Oregon Municipal Bond Fund July 31, 2000 TO OUR SHAREHOLDERS The Municipal Market Environment During the six months ended July 31, 2000, US domestic economic growth remained robust. After growing at a 4.2% annual rate in 1999, US domestic economic growth expanded at a 4.8% rate during the first quarter of 2000 and at a 5.2% rate during the second quarter. However, despite these significant growth rates, few price measure indicators have shown any meaningful signs of future price pressures at the consumer level, despite the lowest unemployment rates since 1970. With few signs of any economic slowdown, the Federal Reserve Board continued to raise short-term interest rates in February, March and May 2000. The Federal Reserve Board cited both the continued growth of US employment and the continued strength of US equity markets as reasons for attempting to moderate US economic growth before inflationary price pressures can occur. However, since then fixed-income markets have largely ignored strong economic fundamentals and concentrated upon very positive technical supply factors. Declining bond issuance--both current, and more importantly, expected future issuance--helped push bond yields lower into mid-April 2000. In late January and early February 2000, the US Treasury announced its intention to reduce the amounts to be auctioned in the quarterly Treasury note and bond auctions. Furthermore, budgetary surpluses allowed the US Treasury to repurchase outstanding, higher-couponed Treasury issues, primarily in the 15-year and longer maturity sector. Both these actions resulted in significant reduction in the outstanding supply of longer-dated maturity US Treasury debt. Domestic and international investors quickly began to accumulate what was expected to become a scarce commodity and bond prices quickly rose. By mid-April 2000, US Treasury bond yields had declined more than 80 basis points (0.80%) to 5.67%. During the remainder of the period, US Treasury bond prices were volatile as strong economic reports and investors' concerns of additional moves by the Federal Reserve Board occasionally overshadowed the positive technical position of the long-term US Treasury bond market. Recently, a number of economic indicators have begun to suggest that the actions taken by the Federal Reserve Board in 1999 and early 2000 have started to affect US economic growth. Both new home sales and consumer spending have slowed, suggesting that economic growth may subside into a 4%--4.5% range by late 2000. In our opinion, this range of growth was targeted by the Federal Reserve Board as being sustainable, given current productivity measures, without endangering the present benign inflationary environment. By June, investor focus returned to the dwindling supply of long-term US Treasury securities and bond prices generally rose for the remainder of the period. The decline in long-term US Treasury bond yields resulted in an inverted yield curve as short-term and intermediate-term interest rates did not fall proportionately to long-term interest rates as the Federal Reserve Board was expected to continue to raise short-term interest rates. The current inversion has had as much to do with debt reduction and US Treasury buybacks as with investor expectations of slower economic growth. During the last six months, US Treasury bond yields have declined more than 70 basis points to end the period at 5.78%, their lowest monthly closing level since May 1999. Tax-exempt bond yields also have declined in recent months. The decline has largely been in response to the rally in US Treasury securities, as well as a continued positive technical supply environment. States such as California and Maryland have announced that their large current and anticipated future budget surpluses will permit the cancellation or postponement of expected bond issuance. Additionally, some issuers have also initiated tenders to repurchase existing debt, reducing the supply of tax-exempt bonds in the secondary market as well. Given the decline in available long-term US Treasury securities, some investors who need longer maturity investment vehicles have begun to consider long-term municipal bonds as potential substitutes. This has further strengthened the over-all positive technical position of the tax-exempt market. During the last six months, long-term municipal revenue bond yields have declined nearly 50 basis points to 5.85%, their lowest level since late August 1999, as measured by the Bond Buyer Revenue Bond Index. The relative underperformance of the municipal bond market in recent months has been especially disappointing given the strong technical position the tax-exempt bond market has enjoyed. The issuance of long-term tax-exempt securities has dramatically declined. During the last year, almost $200 billion in new long-term municipal securities was issued, a decline of almost 20% compared to the same period a year earlier. For the six months ended July 31, 2000, approximately $100 billion in new tax-exempt bonds was underwritten, a decline of 17% compared to the same period in 1999. Merrill Lynch Oregon Municipal Bond Fund July 31, 2000 Although investors received more than $45 billion in coupon payments, bond maturities and the proceeds from early bond redemptions during June and July, overall investor demand has diminished. Long-term municipal bond mutual funds have seen consistent outflows in recent months as the yields of individual securities have risen faster than those of larger, more diverse mutual funds. Thus far this year, tax-exempt mutual funds have had net redemptions of more than $12 billion. However, the rate at which these redemptions have been occurring has slowed in recent months. Recent US equity market volatility, especially in the NASDAQ, has reduced some investor interest in the stock market. This investor interest, especially earlier this year, had been siphoning away demand for municipal bonds by retail investors. Also, the demand from property and casualty companies is expected to increase in the coming months. These firms are becoming more profitable after experiencing losses in the past few years resulting from a series of weather-related natural disasters. Yet as positive as the tax-exempt bond market's technical environment has been for much of this year, investor response to the reduction in both current and future supply of US Treasury bonds has been overwhelmingly positive and municipal bond yields have underperformed their taxable counterparts. Significantly lower municipal bond yields are still likely to require weaker US employment growth and consumer spending. The actions taken in recent months by the Federal Reserve Board should eventually slow US economic growth. Recent declines in US new home sales are perhaps the first sign that consumer spending is being slowed by higher interest rates. Until further signs develop, it is likely that the municipal bond market's current favorable technical position will dampen significant tax-exempt interest rate volatility and provide a stable environment for eventual improvement in municipal bond prices. Fiscal Year in Review For the year ended July 31, 2000, the Fund's Class A, Class B, Class C and Class D Shares had total returns of +2.07%, +1.55%, +1.55% and +1.96%, respectively. (Investment results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 4 and 5 of this report to shareholders.) As a result of our efforts this year, the Fund generated total returns for the 12-month period ended July 31, 2000 that modestly underperformed the average return for all Oregon municipal debt funds, as measured by Lipper Analytical Services, Inc. With interest rates under pressure for much of the fiscal year ended July 31, 2000, our portfolio strategy has been focused on seeking to insulate the Fund from volatility, while still maintaining an attractive dividend. As an asset class, tax-exempt bonds faced tough competition from a surging equity market as well as mounting pressures arising from an aggressive monetary policy designed to curb economic growth and prevent inflation. Until recently, investor appetite for tax-exempt products had waned, as demonstrated by the consistent outflows throughout the mutual fund industry. This environment was also characterized by declining year-over-year municipal issuance. In our last letter to shareholders, we spoke of the various factors contributing to the tax-exempt market's weak performance relative to the Treasury market. At the same time, we noted the compelling value reflected in the yields available on intermediate-term--long-term tax-exempt securities and our growing level of comfort with evolving market fundamentals. Given this investment outlook, we positioned the Fund to further benefit from both a decline in interest rates and a renewed investor appetite for municipal bonds. Merrill Lynch Oregon Municipal Bond Fund July 31, 2000 Initially, portfolio activity consisted primarily of efforts to modestly extend duration (a measure of sensitivity to interest rate fluctuations) as well as to upgrade the average credit quality of our investments. Credit spreads, having already widened appreciably throughout 1999, were still viewed as susceptible to additional pressure and a potential drag on a fixed-income portfolio in a declining interest rate environment. Our efforts, in conjunction with maintaining minimal cash reserves, have resulted in improved performance during the fourth quarter ended July 31, 2000. In an effort to limit volatility, we shifted our portfolio strategy to achieve a more neutral position. While market fundamentals remain positive, the extent of the recent rally combined with the uncertain outcome of the November elections, suggests a more cautious approach in the near term. Oregon's economic recovery from the impact associated with the Asian financial and economic turmoil of 1997 and 1998 continued apace, reflecting the ongoing diversification of the state's economic base. Strengths include improving fund balances, resulting from the receipt of greater-than-expected personal income taxes and a manageable debt burden despite additional capital needs associated with growth. In addition, overall revenues remain strong, largely offsetting increased costs of funding education. Three separate ballot initiatives slated for the upcoming November elections bear watching for the potential negative revenue impact their approval would have on future funding requirements. In Conclusion We appreciate your ongoing interest in Merrill Lynch Oregon Municipal Bond Fund, and we look forward to assisting you with your financial needs in the months and years ahead.

See Notes to Financial Statements. Merrill Lynch Oregon Municipal Bond Fund July 31, 2000 NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: Merrill Lynch Oregon Municipal Bond Fund (the "Fund") is part of Merrill Lynch Multi-State Municipal Series Trust (the "Trust"). The Fund is registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. The Fund's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. The Fund offers four classes of shares under the Merrill Lynch Select Pricing SM System. Shares of Class A and Class D are sold with a front-end sales charge. Shares of Class B and Class C may be subject to a contingent deferred sales charge. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class B, Class C and Class D Shares bear certain expenses related to the account maintenance of such shares, and Class B and Class C Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its account maintenance and distribution expenditures. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--Municipal bonds and other portfolio securities in which the Fund invests are traded primarily in the over-the-counter municipal bond and money markets and are valued at the last available bid price in the over-the-counter market or on the basis of yield equivalents as obtained from one or more dealers that make markets in the securities. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their settlement prices as of the close of such exchanges. Short-term investments with remaining maturities of sixty days or less are valued at amortized cost, which approximates market value. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust, including valuations furnished by a pricing service retained by the Trust, which may utilize a matrix system for valuations. The procedures of the pricing service and its valuations are reviewed by the officers of the Trust under the general supervision of the Trustees. (b) Derivative financial instruments--The Fund may engage in various portfolio investment strategies to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. * Financial futures contracts--The Fund may purchase or sell financial futures contracts and options on such futures contracts for the purpose of hedging the market risk on existing securities or the intended purchase of securities. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. 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 was opened and the value at the time it was closed. (c) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no Federal income tax provision is required. (d) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Interest income is recognized on the accrual basis. Discounts and market premiums are amortized into interest income. Realized gains and losses on security transactions are determined on the identified cost basis. (e) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (f) Dividends and distributions--Dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. Distributions in excess of realized capital gains are due primarily to differing the treatment for futures transactions and post-October losses.
