The municipal bond market faced significant volatility in April, driven by spillovers from a turbulent Treasury market. Treasury yields were pressured higher by rising inflation expectations; the Federal Reserve’s cautious policy stance, reduced foreign demand; hedge fund deleveraging, portfolio shifts toward cash, and structural illiquidity.

The softer tone toward China from the White House, President Trump’s pledge not to fire Federal Reserve (Fed) Chair Jerome (Jay) Powell, and renewed optimism about Fed rate cuts all helped drive a strong market rebound last week.

This week was one of the most volatile weeks in the history of the stock market. That excludes the historic two-day decline on Thursday and Friday the week before (April 3–4). The S&P 500 dropped 1.6% on Tuesday, April 8, surged 9.5% on Wednesday, April 9 (the third biggest up day since 1950), fell 3.5% on Thursday, April 10, and jumped 1.8% on Friday, April 11. The S&P 500 ended up nearly 6% for the week.
