In the final quarter of 2025, the municipal bond market experienced significant momentum, outpacing both U.S. Treasury and corporate bonds. This impressive performance was largely attributable to advantageous market conditions and several interest rate reductions by the Federal Reserve, underscoring the resilience and appeal of municipal debt instruments.

Specifically, the BNY Mellon High Yield Municipal Bond Fund's Class I shares posted a 1.73% return for the quarter ending December 31, 2025, exceeding the Bloomberg U.S. Municipal Bond Index's return of 1.56%. A key highlight was the superior performance of bonds with the lowest investment-grade ratings, as evidenced by the Bloomberg Municipal BBB Index's 1.77% return, which surpassed those of AAA, AA, and A-rated municipal bonds. This indicates a strong appetite for higher-yielding municipal assets within the investment-grade spectrum.

Looking forward, the year 2026 is projected to witness a substantial increase in municipal bond issuance. This anticipated supply surge is driven by critical funding requirements for aging infrastructure, escalating capital expenditure costs, and the diminishing impact of pandemic-era financial aid. Such conditions are expected to sustain high demand for municipal bonds, continuing to offer appealing tax-equivalent yields for investors.

The current investment strategy maintains a neutral to moderately long duration stance relative to established benchmarks. This approach is predicated on the belief that bonds with maturities of 15 years or longer present attractive yield opportunities, particularly within a yield curve environment that remains relatively steep. This strategic positioning aims to capitalize on long-term value in the municipal bond sector.

The municipal bond market's strong close to 2025, characterized by outperformance and favorable technicals, sets a positive tone. With expectations of increased supply in 2026 and a strategic focus on longer-duration bonds, the market appears poised for continued investor interest and robust activity.
