T. Rowe Price High Income Municipal ETF (THYM) is an actively managed exchange-traded fund that seeks to provide a high level of federally tax-exempt income by investing primarily in longer-term, low- to upper-medium quality municipal bonds; it may also allocate to high-yield municipal securities and derivatives for income enhancement and risk management. The fund offers exposure to the municipal bond market segment, targeting investors seeking tax-advantaged fixed income with potential for higher yields through active management strategies. THYM trades on the NASDAQ exchange with a net expense ratio of 0.32%.
Launched on November 20, 2025, as part of T. Rowe Price's expansion of its active fixed income ETF lineup to 28 offerings, THYM represents a strategic addition to the firm's municipal bond strategies alongside the Short Municipal Income ETF (TMNS), Long Municipal Income ETF (TMNL), and Multi-Sector Income ETF (TMSF). The fund is managed by Jim Murphy, CFA, Head of the Municipal Bond team with 31 years of experience, and co-portfolio managers Colin Bando (14 years) and Michael Kane (16 years). This launch builds on T. Rowe Price's prior introduction of the Intermediate Municipal Income ETF (TAXE) in 2024, enhancing its suite of tax-free income solutions for retail and institutional investors.
