Munis Head for Best October in More Than Four Decades After Rout

US state and local government debt is on track to notch its strongest October in more than four decades, as a relief rally follows one of the worst months for the bond market in years.

The Bloomberg Municipal Bond Index has gained roughly 3.6% so far this month through Thursday, putting it on pace for its best October since at least 1980 and its strongest month since November 2023. It would also mark the first month of positive returns since June, following months of declines fueled by concerns about inflation and interest-rate hikes.

Cheaper valuations and elevated yields led to October’s rebound, according to experts. Investors are also putting money back into munis after they sold in September to harvest tax-losses.

“A lot of people all at once are interested in the asset class for different reasons, but I think it is a value play right now,” said Eric Kazatsky, client portfolio manager at MacKay Municipal Managers. Higher yields are now attracting a deeper pool of investors, he said.

September’s selloff pushed muni yields to levels investors hadn’t seen since at least 2011 and left the market with its weakest monthly performance since 2008.
