American Century's California High-Yield Municipal Fund declined 0.04% in Q1 2026, outperforming its benchmark which fell 1.00%. Surging interest rates in March drove the quarter's decline, with municipal bond yields rising faster than Treasury yields. The volatile period included renewed tariff concerns, Federal Reserve policy pause, mixed economic data, war in Iran, and soaring oil prices that fueled inflation worries. Sector allocations drove outperformance, particularly an underweight position in underperforming industrial development revenue securities and overweights in special assessment and charter schools sectors. Security selection also aided performance across hospital, special assessment, local general obligation, retirement community, and water/sewer sectors. The managers have modestly tempered their economic outlook due to energy shocks but still expect improvement from late 2025, with growth settling around 2% annually. Given tight valuations, they remain cautious and selective, favoring seasoned credits with financial flexibility while seeing attractive value in energy prepay, multifamily housing, and development district sectors.
