In March, with the outbreak of the COVID-19 pandemic in the United States, the market for municipal securities was severely stressed: mutual fund redemptions sparked unprecedented selling of municipal securities, yields increased sharply, and issuance dried up. In this post, we describe the evolution of municipal bond market conditions since the onset of the COVID-19 crisis. We show that conditions in municipal markets have improved significantly, in part a result of the announcement and implementation of several Federal Reserve facilities. Yields have decreased substantially, mutual funds have received significant inflows, and issuance has rebounded. These improvements in municipal market conditions help ensure that state and local governments have better access to funding for critical capital investments.
