Monthly Municipal Market Update, September 2021

September month in review

September was a volatile month for U.S. markets, with notable levels of activity exhibited in both equity and fixed income markets. The largest driver of fixed income market activity in September was the Federal Open Market Committee’s meeting, at which Fed officials indicated a possible near-term start to tapering their asset purchase program, as well as the possibility for rate hikes as soon as the end of 2022.Footnote1 This more hawkish tone, relative to previous messaging, resulted in an increase in Treasury yields. At month end, the 1-, 5-, 10-, and 30-year tenors of the Treasury curve yielded 0.08% (up 1 basis point), 0.99% (up 22 basis points), 1.53% (up 23 basis points), and 2.09% (up 16 basis points), respectively.Footnote2

Municipal bond yields also increased in September across the AAA Municipal Market Data (MMD) yield curve. Yields inside the five-year tenor rose by 5 to 9 basis points (bps), while yields at the five-year tenor and beyond increased by double digits. The greatest increase occurred at the 10-year tenor, which ended September at 1.14%, up 22 bps from the end of August.Footnote3 Municipal bond mutual funds continued to attract investors, adding another four straight weeks of inflows for a total of $4.3 billion in September. This brings the running total to 30 consecutive weeks of inflows. So far this year, municipal bond funds have added $74.3 billion.Footnote4
