The 10-year Treasury yield has been the topic of conversation lately among fixed-income investors. Earlier this month, the T-note closed above 3 percent for the first time since July 2011, prompting some market watchers to call time on the three-decade Treasury bull market. (Bond prices fall as yields rise, and vice versa.) For other investors, these concerns might extend into the $3.8 trillion municipal bond market.
I believe this bearishness is premature. Take a look at the chart below, which shows the 10-year yield’s daily standard deviation based on 10 years’ worth of data. As of Friday, May 18, the yield was up a little more than two standard deviations from its mean—suggesting that, while not guaranteed, there’s a high probability of mean reversion. Such a move would bring the 10-year yield back down to around 2.88 percent, a level last seen in mid-April. This would be similarly positive for muni bonds, though it’s important to remember that Treasuries, unlike munis, are backed by the full faith and credit of the U.S. government.
Muni Bonds Outperformed in Previous Rate Hike Cycles
Fixed-income investors might find munis more attractive than Treasuries right now for two additional reasons.
For one, muni bonds historically outperformed and were less volatile than Treasuries during previous rate hike cycles, according to Standish data. In the past, a 100 basis point rise in the 10-year Treasury yield—in response to higher interest rates—was accompanied by a rise of only 60 basis points on average in muni bond yields.
Take a look below. In each of the past seven rate hike cycles, munis outperformed Treasuries by at least 5 percent and sometimes as much as 10 percent or more. The Federal Reserve has raised rates six times since December 2015, with two more increases possibly slated for this year.
