In the second quarter of 2025, the Columbia High Yield Municipal Fund's performance lagged its established benchmark. This deviation was largely attributed to the fund's investment strategy, which favored a longer duration profile, impacting returns amidst fluctuating market conditions. The period was characterized by heightened volatility, influenced by multiple economic catalysts and policy decisions. Despite these dynamics, the fund continued its proactive management, including significant portfolio adjustments aimed at enhancing overall yield.

The financial markets in the second quarter of 2025 were notably turbulent, with a series of events contributing to an environment of uncertainty. A key element shaping the market landscape was the U.S. Federal Reserve's consistent approach to monetary policy. Throughout both May and June, the central bank opted to keep short-term interest rates unchanged, maintaining them within the 4.25%–4.50% range. This stability in interest rates, however, did not insulate the market from broader uncertainties, as various economic indicators and geopolitical developments fueled investor caution.

Amidst this backdrop of volatility and steady interest rates, the municipal bond market demonstrated robust activity. The quarter witnessed an unprecedented volume of new issuance, reaching a total of $161 billion. This surge in new municipal bonds provided the Columbia High Yield Municipal Fund with opportunities to adjust its holdings. The fund's managers strategically engaged in swapping lower book yield positions for those offering higher book yields, demonstrating an adaptive approach to market conditions in pursuit of improved returns.

The Columbia High Yield Municipal Fund’s performance during the second quarter of 2025 highlights the intricate relationship between fund strategy, market volatility, and central bank policies. Despite the fund's underperformance relative to its benchmark, its management actively sought to optimize its portfolio composition by pivoting towards higher-yielding assets. This strategic repositioning was a direct response to the challenging yet dynamic market conditions, including a notable increase in new municipal bond issuances.
