Municipal Market Overview  For the Reporting Period Ended April 30, 2020

Municipal Market Conditions

Municipal bonds posted modestly positive total returns amid a bifurcated market narrative in which rallying interest rates and favorable technicals drove strong performance early in the period before sentiment changed as implications of the coronavirus pandemic materialized. During the month of March, municipal bonds experienced volatility that was worse than during the height of the global financial crisis, as performance plummeted -10.87% during a two-week period before rebounding on aggressive valuation-based buying (For comparison, the -11.86% correction in 2008 spanned more than a month.) Performance continued to be hindered in April by the negative fundamental impacts of the prolonged economic shutdown, despite numerous stimulus efforts by the Fed.

During the same time period, tax-exempt municipal bonds significantly underperformed U.S. Treasuries across the yield curve. Relative valuations, which had been broadly stretched since the passage of tax reform, reset to levels not seen since 2008. This has resulted in increased participation from crossover investors in a market that has mainly been driven by retail over the past few years.

Financial Conditions of Municipal Issuers

The coronavirus pandemic is an unprecedented shock to the system impacting nearly every sector in the municipal market. Luckily, most states and municipalities were in excellent fiscal health before the crisis and the federal government has provided an incredible amount of support. Ongoing stability is expected in high-quality states as well as school districts and local governments given that property taxes have proven resilient in past economic downturns. Essential public services such as power, water, and sewer are protected segments. State housing authority bonds, flagship universities, and strong national and regional health systems are well positioned to absorb the impact of the economic shock. However, some segments are facing daunting financial challenges and federal support may be insufficient, requiring issuers to draw down reserves and/or borrow to meet financial obligations. Critical providers (such as safety net hospitals, mass transit and airports) with limited resources will require funding from the states and broader municipalities they serve. We anticipate that a small subset of the market, mainly non-rated stand-alone projects, will experience significant credit deterioration. Assuming the worst case, a prolonged recession would likely mean a spate of defaults, primarily in non-rated credits, and the migration of the municipal market’s overall credit quality from double-A to a still-strong single-A rating. As a result, we advocate careful credit selection and anticipate increased credit dispersion as the market navigates near-term uncertainty.

The opinions expressed are those of BlackRock as of April 30, 2020 and are subject to change at any time due to changes in market or economic conditions. The comments should not be construed as a recommendation of any individual holdings or market sectors. Investing involves risk, including loss of principal. Bond values fluctuate in price so the value of your investment can go down depending on market conditions. Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments. There may be less information on the financial condition of municipal issuers than for public corporations. The market for municipal bonds may be less liquid than for taxable bonds. Some investors may be subject to Alternative Minimum Tax (“AMT”). Capital gains distributions, if any, are taxable.

The S&P Municipal Bond Index, a broad, market value-weighted index, seeks to measure the performance of the U.S. municipal bond market. All bonds in the index are exempt from U.S. federal income taxes or subject to the AMT. Past performance is no guarantee of future results. Index performance is shown for illustrative purposes only. It is not possible to invest directly in an index.

The Benefits and Risks of Leveraging

The Funds may utilize leverage to seek to enhance the distribution rate on, and net asset value (“NAV”) of, their common shares (“Common Shares”). However, there is no guarantee that these objectives can be achieved in all interest rate environments.

In general, the concept of leveraging is based on the premise that the financing cost of leverage, which is based on short-term interest rates, is normally lower than the income earned by a Fund on its longer-term portfolio investments purchased with the proceeds from leverage. To the extent that the total assets of each Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Fund’s shareholders benefit from the incremental net income. The interest earned on securities purchased with the proceeds from leverage (after paying the leverage costs) is paid to shareholders in the form of dividends, and the value of these portfolio holdings (less the leverage liability) is reflected in the per share NAV.

To illustrate these concepts, assume a Fund’s Common Shares capitalization is $100 million and it utilizes leverage for an additional $30 million, creating a total value of $130 million available for investment in longer-term income securities. If prevailing short-term interest rates are 3% and longer-term interest rates are 6%, the yield curve has a strongly positive slope. In this case, a Fund’s financing costs on the $30 million of proceeds obtained from leverage are based on the lower short-term interest rates. At the same time, the securities purchased by a Fund with the proceeds from leverage earn income based on longer-term interest rates. In this case, a Fund’s financing cost of leverage is significantly lower than the income earned on a Fund’s longer-term investments acquired from such leverage proceeds, and therefore the holders of Common Shares (“Common Shareholders”) are the beneficiaries of the incremental net income.

However, in order to benefit Common Shareholders, the return on assets purchased with leverage proceeds must exceed the ongoing costs associated with the leverage. If interest and other costs of leverage exceed a Fund’s return on assets purchased with leverage proceeds, income to shareholders is lower than if the Fund had not used leverage. Furthermore, the value of the Funds’ portfolio investments generally varies inversely with the direction of long-term interest rates, although other factors can influence the value of portfolio investments. In contrast, the value of each Fund’s obligations under its respective leverage arrangement generally does not fluctuate in relation to interest rates. As a result, changes in interest rates can influence each Fund’s NAVs positively or negatively. Changes in the future direction of interest rates are very difficult to predict accurately, and there is no assurance that a Fund’s intended leveraging strategy will be successful.

The use of leverage also generally causes greater changes in each Fund’s NAV, market price and dividend rates than comparable portfolios without leverage. In a declining market, leverage is likely to cause a greater decline in the NAV and market price of a Fund’s Common Shares than if the Fund were not leveraged. In addition, each Fund may be required to sell portfolio securities at inopportune times or at distressed values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments, which may cause the Fund to incur losses. The use of leverage may limit a Fund’s ability to invest in certain types of securities or use certain types of hedging strategies. Each Fund incurs expenses in connection with the use of leverage, all of which are borne by Common Shareholders and may reduce income to the Common Shares. Moreover, to the extent the calculation of each Fund’s investment advisory fees includes assets purchased with the proceeds of leverage, the investment advisory fees payable to the Funds’ investment adviser will be higher than if the Funds did not use leverage.

To obtain leverage, each Fund has issued Variable Rate Demand Preferred Shares (“VRDP Shares”) or Variable Rate Muni Term Preferred Shares (“VMTP Shares”) (collectively, “Preferred Shares”) and/or leveraged its assets through the use of tender option bond trusts (“TOB Trusts”) as described in the Notes to Financial Statements.

Under the Investment Company Act of 1940, as amended (the “1940 Act”), each Fund is permitted to issue debt up to 33 1/3% of its total managed assets or equity securities (e.g., Preferred Shares) up to 50% of its total managed assets. A Fund may voluntarily elect to limit its leverage to less than the maximum amount permitted under the 1940 Act. In addition, a Fund may also be subject to certain asset coverage, leverage or portfolio composition requirements imposed by the Preferred Shares’ governing instruments or by agencies rating the Preferred Shares, which may be more stringent than those imposed by the 1940 Act.

If a Fund segregates or designates on its books and records cash or liquid assets having a value not less than the value of a Fund’s obligations under the TOB Trust (including accrued interest), then the TOB Trust is not considered a senior security and is not subject to the foregoing limitations and requirements imposed by the 1940 Act.

Derivative Financial Instruments

The Funds may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the instrument. The Funds’ successful use of a derivative financial instrument depends on the investment adviser’s ability to predict pertinent market movements accurately, which cannot be assured. The use of these instruments may result in losses greater than if they had not been used, may limit the amount of appreciation a Fund can realize on an investment and/or may result in lower distributions paid to shareholders. The Funds’ investments in these instruments, if any, are discussed in detail in the Notes to Financial Statements.

Investment Objective

BlackRock MuniAssets Fund, Inc.’s (MUA) (the “Fund”) investment objective is to provide high current income exempt from U.S. federal income taxes by investing primarily in a portfolio of medium- to lower-grade or unrated municipal obligations, the interest on which, in the opinion of bond counsel to the issuer, is exempt from U.S. federal income taxes. The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in municipal bonds exempt from U.S. federal income taxes (except that the interest may be subject to the U.S. federal alternative minimum tax). The Fund invests at least 65% of its assets in municipal bonds that are rated in the medium to lower rating categories by nationally recognized rating services (for example, Baa or lower by Moody’s Investors Service, Inc. (“Moody’s”) or BBB or lower by S&P Global Ratings, or securities that are unrated but are deemed by the investment adviser to be of comparable quality at the time of investment. The Fund may invest directly in such securities or synthetically through the use of derivatives.

No assurance can be given that the Fund’s investment objective will be achieved.

Fund Information

Performance results may include adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles.

Past performance is not indicative of future results.

The following discussion relates to the Fund’s absolute performance based on NAV:

Municipal bonds performed well for most of the period due to the accommodative Fed policy and favorable supply-and-demand trends in the market. This supportive backdrop changed abruptly in March once the spread of the coronavirus pandemic led to travel restrictions, business closures and stay-at-home orders. The prospect of a sharp economic downturn led to significant, broad-based weakness across the financial markets. Tax-exempt issues were hard hit in the sell-off, as investors withdrew cash from municipal bond funds and a lack of market liquidity inhibited efficient pricing. Municipal bonds subsequently recovered in April following aggressive stimulus from the Fed and U.S. Congress, allowing the category to close the period with a narrow gain. High-yield municipal bonds lagged the investment-grade space by a considerable margin, as investors gravitated to areas with the lowest credit risk.

Prior to the March downturn, the Fund benefited from its investments in longer-dated securities with maturities of 20 years and above. Holdings in below investment grade and unrated securities also aided performance in this time, as did positions in the tobacco, tax-backed and health care sectors. Once the market turned lower, these same factors detracted from results and were the primary reason for the Fund’s negative return for the full period.

The Fund’s use of U.S. Treasury futures to manage interest rate risk also proved detrimental to the Fund’s performance given the breakdown in correlation between the Treasury and municipal markets arising from the coronavirus pandemic. While municipal bond yields rose due to a substantial increase in yield spreads, Treasury yields declined amid investors’ “flight to quality.” (Prices and yields move in opposite directions.) The Fund’s use of leverage also weighed on the Fund’s results at a time of falling bond prices.

The Fund was positioned somewhat defensively at the end of April, albeit less so than earlier in the reporting period.
