Month in review

Monthly municipal bond issuance in September totaled $35.4 billion, surpassing $35 billion for only the third time this year. AAA municipal yields rose by at least 17 basis points (bps) across the curve, with the greatest increase of 25 bps month-over-month occurring at the 1-year tenor.1

  • On September 18, the Federal Reserve cut interest rates by a quarter point, with Chair Powell leaving the door open to additional cuts but declining to offer assurance. The move marked the Fed’s second such action this summer to aid the continuation of the current expansion. The Fed also injected billions into overnight repo markets starting on September 17 to keep the Secured Overnight Financing Rate (SOFR) in check.2
  • The Bloomberg Barclays Municipal Bond Index returned -0.80% in September, as higher yields across the curve resulted in the first month of losses for the broad municipal bond market since October 2018.3
  • Muni/Treasury ratios increased across the curve in September. Notably, the two-year ratio moved from 67% to 75%, and the 10-year ratio increased from 81% to 85%.4
  • September’s primary market issuance of $35.4 billion represented a 7.9% decrease from August 2019 but a 40.3% increase over September 2018.5
  • Secondary market trade volume slowed during September, with par traded totaling just $225 billion and the quantity of trades tallying just 630,000 (down 8.8% and 5.3% from August, respectively). The latter marks the fifth straight month of declining trades.6
