US municipal bonds, also known as muni bonds or munis, are bonds issued by US states, cities or local government bodies. They can take the form of general obligation (GO) bonds, funded via tax revenues, or revenue bonds, secured by an income stream from a specific local infrastructure asset. Historically, this has meant that default rates have been low, and risk adverse investors could consider investing in munis as a way to diversify corporate bond holdings.

The majority of municipal bonds are issued in a format that exempts the holder from US federal income tax, and potentially local state taxes – a significant benefit for many US domiciled citizens and corporates. However, there is a growing section of the municipal bond market that is issued in a fully taxable format – by issuing fully taxable debt, the issuer has greater flexibility on how they can use the proceeds. Taxable municipal bonds generally trade with a higher gross yield than their tax-exempt counterparts, and this has led to an increase in demand from non-US investors.

Today, the US municipal bond market supplies around 80% of the capital needed for US infrastructure maintenance and development[1]. Currently, there are 56,248 issuers in the market; this represents almost USD4 trillion in lending[2].

From an investment perspective, US municipal bonds are seen as a high-quality asset class. Individual US states that issue infrastructure-related bonds might be major economies in their own right, with levels of growth comparable to that of sovereign countries. For example, the gross domestic product of California alone is equivalent to that of the United Kingdom[3].

The left-hand graph below shows the ratings of all US municipal bonds versus global corporate bonds, with ‘Aaa’ being the highest and C the lowest. As you can see, most US municipal bonds fall within the higher-quality end of the ratings scale.

Meanwhile, the right-hand table demonstrates the relatively lower defaults among US municipal bonds in relation to global corporate bonds. It also reveals that recovery rates for municipal bonds are higher than those of senior unsecured global corporate bonds. This means investors may have a better chance of getting some of their money back if a US municipal bond defaults.

In this table, we show how the performance of the US municipal bond market compares to other types of fixed-income instruments. From January 1997 to September 2021, for every 1% of growth in the US municipal bond market, you would have achieved only 0.68% had the same amount been invested in investment-grade bonds or 0.52% from US Treasuries.

We often hear the term “monetary tightening”. What this refers to is the process of raising interest rates. Central banks often do this to cool an overheating economy, as higher interest rates make borrowing more expensive. Higher interest rates can also make the interest paid out by some bonds look less appealing, as investors could potentially find higher rates elsewhere.

In the graph below, we show that despite increases in US interest rates, based on historical data, municipal bond performance (including reinvestment of income) were able to deliver positive returns. Investors may consider US municipal bonds in an adverse performance environment for fixed income.

The bars labelled “Muni” are representative of the Bloomberg Barclays US Municipal Index’s total returns in the corresponding years on the X-axis (i.e. 1994/1995, 1999/2000, 2004-2006 and Dec 2015 – Dec 2018). The time periods depicted in the chart are the most recent instances where the Federal Reserve tightened monetary policy, or raised interest rates (as shown by the green bar representing the magnitude of rate hikes). Similarly, the blue bars show the relative performance of several distinct municipal indices during the same time period (delivering positive returns).

• General obligation bonds risk — general obligation bonds are secured by the full faith, credit, and taxing power of the municipality issuing the obligation. As such, timely payments depend on the municipality’s credit quality, ability to raise tax revenues and ability to maintain an adequate tax base.
• Revenue bonds risk — revenue bonds with payments depend on the money earned by the particular facility or class of facilities, or the amount of revenues derived from another source. If the specified revenues do not materialize, then the bonds may not be repaid.
• Adverse economic, political or regulatory changes or adverse factors such as additional costs, competition, environmental concerns, taxes, and changes in end-user numbers in infrastructure sectors and projects can significantly affect the revenue generated and the overall market. This may lead to defaults on payment of principal or interest of the municipal bonds. The federal government of the US are not obliged to support any municipal bonds in default. The Fund could suffer substantial loss.
• There are specific risks associated with municipal bonds including different disclosure requirements, lesser degree of transparency compared to other bond markets. Municipal bonds may also be subject to call or prepayment risks. There are specific risks associated with certain municipal sectors that the fund may invest, including general obligation bonds risk, revenue bonds risk, private activity bonds risk, moral obligation bonds risk, municipal notes risk and municipal lease obligations risk.
