Last week, the muni market saw a "slowdown in activity" after the asset class saw its best monthly performance in nearly two years, said Birch Creek strategists.

The Texas Transportation Finance Corp. leads the new-issue calendar with $1.739 billion of subordinate tier toll revenue and refunding bonds, followed by New York City with $1.5 billion of general obligation bonds.

Supply is expected to rebound in October, when BofA Securities estimates that issuance will reach $58 billion.

Sophisticated issuers and investors shared insights into how they navigate the complexities of the municipal bond market at The Bond Buyer Infrastructure event.

October has historically not been "particularly kind to the municipal market, as it tends to be one of the heavier supply months of the year," said Daryl Clements, a portfolio manager at AllianceBernstein.

The muni market may be shaken by a government shutdown, driving short-term volatility and wider spreads, said James Pruskowski, a public finance strategist.

Muni yields rose up to eight basis points, depending on the scale, with the largest losses again on the front-end of the curve.

The short-end correction has been "driven by a solid labor market report, which pushed Treasury yields higher as expectations for additional Fed rate cuts tempered," said Alice Cheng, director of municipal credit and investor strategy at Janney.

Munis have outperformed USTs and corporates by more than 1.0% month-to-date on the heels of this rally so far, BofA strategists said.

Munis saw cuts, albeit small ones, for the first time in nearly two weeks as yields rose up to four basis points, depending on the scale.

Capital Group joins a small, but growing number of shops that have added, or considered adding, muni ETFs to their model portfolios.

By the close, muni yields were bumped up to four basis points, depending on the curve, while UST yields rose two to five basis points.

"This was a much-needed rally as the long end struggled throughout the year, but now has been pushed back into positive territory," said Jason Wong, vice president of municipals at AmeriVet Securities.

Investors added $2.183 billion to municipal bond mutual funds in the week ended Wednesday, following $623.3 million of inflows the prior week, according to LSEG Lipper data.

October is looking to be another blockbuster month for supply, with several $1 billion-plus deals on the shadow calendar, said Pat Luby, head of municipal strategy at CreditSights. 

The muni market is in a position to rally in the latter part of this year, said Daryl Clements, a portfolio manager at AllianceBernstein.

Monday's rally is a "continuation of what we are seeing," as the market is actively repositioning where it needs to go, said Alice Cheng, director of municipal credit and investor strategy at Janney.

The market strength is a carryover from Friday, when munis rallied upo 12 basis points after a weaker-than-expected jobs report solidified expectations for a September rate cut. This was the largest single-day rally since April.

Muni yields were bumped two to 12 basis points, depending on the scale, with the largest gains out long, and UST yields fell six to nine basis points, pushing the two-year UST to its lowest levels in over two years.

The rally stemmed from the weak nonfarm payrolls report and revisions brought down the three-month average to 29,000 jobs per month, further solidifying the chance of a rate cut in September, said Chris Brigati, managing director and CIO at SWBC.
