Munis are less likely to outperform Treasuries in the second half of the year due to technical factors related to tax reform.
We have a favorable view of the muni market, and think credit conditions for most state and local governments are either stable or improving despite some pockets of stress.
We suggest muni investors focus on higher-rated munis, and target an average duration between five and eight years.
Munis outperformed both Treasuries and corporate bonds during the first half of 2018, but we think that trend could reverse in the second half of the year. We see some headwinds on the horizon for the muni market. However, we think focusing on higher-rated munis, and keeping average duration within five and eight years, can help investors mitigate the effect of those headwinds on their portfolios.
Despite the headwinds, we have a favorable view of the muni market
Munis are still an attractive investment option for high-net-worth investors, in our view. Although we think we are in the later stages of the economic cycle, and that could strain credit conditions for some municipalities, credit quality for most municipal bonds is already generally high to begin with. In fact, nearly two-thirds of the munis in a broad municipal bond index are rated either AAA or AA1—the two highest rungs possible.
Moreover, municipal bonds continue to yield more than Treasury bonds and corporate bonds, with comparable ratings and maturities, after taxes for higher income earners, reinforcing their position as a relatively attractive option for a bond allocation in taxable accounts. As shown in the chart below, munis yield more than corporate bonds after taxes for investors in the 32% and higher federal tax brackets.

Last, the recent rise in short-term yields has enhanced the attractiveness of municipal bond yields on an absolute basis. Today, the yield for a one-year AAA-rated municipal bond index is 1.5%. For comparison, in fall 2017 a seven-year AAA-rated index was yielding 1.5%. Today, investors can get higher yields without having to take on a large amount of interest rate risk.
Focus on higher-rated munis
Although we don’t anticipate a recession any time soon, we believe we are in the later part of the economic cycle, and think muni investors should start preparing for a potential economic slowdown. Lower-rated muni issuers tend to have less financial flexibility to meet debt service, and during an economic slowdown their finances may be further strained, which could result in ratings downgrades. When a bond is downgraded its price generally falls. Moreover, today the additional compensation—called a spread—for investing in lower-rated parts of the investment-grade muni market is the narrowest it has been since the 2008 credit crisis. Today, we think higher-rated munis—AAA and AA—offer a more attractive risk/reward balance.

Munis have outperformed Treasuries and corporate bonds so far this year
Munis outperformed Treasuries and corporate bonds largely due to tax reform, but that trend could reverse. When the 2017 tax reform was being debated, Congress proposed eliminating issuance of certain types of tax-exempt munis. Due to the potential restrictions, bankers rushed to get deals done that would have otherwise likely been done in the first half of this year. As a result, issuance of munis spiked in the latter part of 2017 and largely dried up at the beginning of 2018. The limited supply of new munis this year helped the municipal bond market outperform both the corporate and Treasury markets. However, due to the rise in yields for long-term Treasuries, investment-grade muni returns are still negative year to date.

The level of new munis coming to the market has since returned to closer to its longer-term average, which will likely make it harder for munis to outperform Treasury and corporate bonds going forward. However, we believe returns will likely be positive for the second half of the year, because we don’t think yields for longer-term Treasuries will increase as much as they have during the first half of the year. Municipal bond yields tend to follow the direction of Treasury bond yields. For more on the outlook for the Treasury market read Kathy Jones’ recent commentary.

Relative valuations remain stretched
Relative value in the municipal bond market is often measured by the municipals-over-bonds (MOB) spread. The spread compares the yield on an AAA-rated municipal bond to the yield on a Treasury bond of similar maturity before taxes. All else being equal, a higher ratio means munis are more attractive relative to Treasuries.
As shown in the chart below, the MOB spread for all maturities is below their five-year averages. Relative valuations for shorter-term munis are even further below their longer-term averages compared to longer-term munis.

The lower the MOB spread, generally, the less attractive munis are relative to Treasuries. Historically, they’ve also been less likely to outperform Treasuries when the MOB spread is lower, as shown in the chart below. For example, when the 10-year MOB spread has been below 90%, munis have underperformed Treasuries by 1.3% on average over the subsequent 12 months. For comparison, when the 10-year MOB spread was above 100%, munis have outperformed Treasuries by 3.1% on average over the following 12 months. The 10-year MOB spread is currently 85.5%.
Munis are less likely to outperform Treasuries at lower relative valuations

We believe that coupons and not price appreciation will drive returns for municipal bonds in the latter half of 2018. Longer term, we also believe that we are near the peak of the cycle of rising rates for intermediate- and longer-term bonds. Therefore, we don’t view further increases in interest rates as being a major headwind for munis in the latter half of the year.
What to do now
Review your fixed income portfolio including your allocation to muni bonds. While we believe interest rates for intermediate- and longer-term Treasuries are near peaking in this recovery cycle and into the end of 2018, we suggest that muni investors focus on higher-rated bonds and issuers due to a potential pending economic slowdown and credit risk.
