Investors are flocking to municipal bond funds at the fastest rate in five years, drawn by attractive tax-free yields and recovering market performance. Despite potential macroeconomic risks, experts at AllianceBernstein and UBS see compelling opportunities for strong returns over the next 12-18 months, particularly in longer-duration bonds and essential service revenue credits.

Muni Bond Funds See Record Inflows: Why Investors Are Piling Into Tax-Exempt Debt
Demand for municipal bonds remains robust, with investors pouring into muni bond funds at the fastest pace seen in five years. Despite some volatility earlier in the year, the asset class is showing strong performance and attractive yields, leading experts to believe these "good times" may persist.
A Rebound and Strong Demand
After a dismal March, municipal bonds rebounded in April, with the ICE BofA US Municipals Securities Index achieving its strongest April performance since 2014. This resurgence has fueled significant investor interest. Municipal mutual and exchange-traded funds have seen net inflows of approximately $22.3 billion in the first four months of the year, according to LSEG Lipper Global Fund Flows. This influx marks the fastest rate of investment in muni funds since 2021.
Attractive Yields and Valuations
Experts point to the compelling income generation potential of municipal bonds. "The all-in yields are still over attractive from an income generation perspective," notes Matt Norton, chief investment officer for municipal bonds at AllianceBernstein. He highlights that a 4% tax-free yield can translate to a tax-equivalent yield approaching 7% for investors in higher tax brackets. Norton believes that given the relative safety and attractive valuations, municipal bonds could deliver strong performance over the next 12 to 18 months.
UBS has also turned positive on the asset class, shifting its house view to "attractive." Senior fixed income strategist Sudip Mukherjee cited attractive yields, expected improvements in technicals, a steep curve, and resilient credit as reasons for their optimistic outlook, predicting strong performance in the coming months.
Navigating Potential Risks
While the outlook is largely positive, analysts advise caution. Barclays' Mikhail Foux, head of municipal research and strategy, warns that increased macroeconomic risk, such as rising geopolitical tensions, could lead to greater rate volatility. Investors might benefit from exercising caution and looking to "add on weakness" if opportunities arise.
Finding Opportunities in the Muni Market
Despite expectations of ample supply this year, demand is seen as sufficient due to attractive valuations and solid income. Norton specifically favors longer-term bonds (15- to 30-year maturities) and credits with ratings of A, BBB, or higher, citing their strong credit fundamentals and appealing valuations. Within revenue bonds, he prefers sectors like affordable housing and senior housing due to high occupancy rates and low historical default rates.
UBS is also favoring the 20-year portion of the curve for long-term absolute returns, recommending a portfolio leaning towards high-quality assets (75% AAA/AA, 25% A). Eric Kazatsky at MacKay Shields has shifted focus from general obligation to revenue bonds, particularly essential service credits like water, sewer, and public power, due to better relative value and stronger covenant protection. He also finds the 17- to 22-year segment of the curve most attractive, noting that munis are outperforming Treasuries and corporates given their lower risk profile.
