Midsummer Muni Musings

As the summer doldrums roll on, we thought it was a good time to recap where the muni market has come since the Trump sell-off of last fall.

A number of factors have helped the overall muni market.

The general level of interest rates has fallen as a result of congressional inertia on tax bills, healthcare, and fiscal spending in general. Markets, both equity and fixed income, generally like congressional gridlock, and we have it now, even with both houses of Congress and the presidency controlled by the Republicans. The charts below show the changes in the US Treasury market and the AAA tax-free bond market since the end of the first quarter. The muni outperformance in the long end is evident. The AAA-to-US Treasury yield ratio is now below 100%, though most AA- and A-rated bonds are still at yield ratios that are historically cheap.
