The municipal market muscled through this week by holding yields mostly steady as investors digested a large new-issue slate, heavy on tax-exempt paper, even as U.S. Treasuries were weaker until Friday’s session.

Municipal triple-A yield curves closed out the week with few changes, valuations were little changed — though at attractive levels — and the forward calendar climbs to more than $10 billion to open the fourth quarter.

“Munis have continued proving their underlying strength in the past week, in the face of one of the heaviest supply weeks in recent history and somewhat higher Treasury rates,” said Mikhail Foux, managing director and head municipal research and strategy at Barclays. “All deals are getting heavily oversubscribed, and MMD-UST ratios actually declined slightly this week.”

The two-year muni-to-Treasury ratio Friday was at 65%, the three-year at 66%, the five-year at 66%, the 10-year at 70% and the 30-year at 86%, according to Refinitiv Municipal Market Data’s 3 p.m. EST read. ICE Data Services had the two-year at 63%, the three-year at 64%, the five-year at 64%, the 10-year at 69% and the 30-year at 85% at 4 p.m.

“On the one hand, with four or five heavy supply weeks ahead of us, it would be hard not to expect tax-exempts to underperform Treasuries, at least to a degree,” Foux said. “On the other hand, many market participants are expecting to buy the dip, and, as we know, the market typically does not do what investors foresee, and we would not be surprised if munis do not underperform much.”

Municipal volume is estimated at $10.14 billion for the week of Sept. 30. There are $7.769 billion of negotiated deals on tap and $2.372 billion of competitive loans.

The negotiated calendar is led by a $1 billion-plus Northwell Healthcare deal via the Dormitory Authority of the State of New York while the competitive calendar is led by the New York Metropolitan Transportation Authority, which is set to sell Tuesday nearly $872 million of dedicated tax fund green Climate Bond Certified bonds in two sales, $399.74 million of which are refunding bonds. 

Bond Buyer 30-day visible supply sits at $15.83 billion.

“These levels of supply are not particularly surprising as issuers pull forward deals ahead of November, consistent with prior election years,” said Peter DeGroot in a Friday market comment. “The central assumption underpinning our belief that ratios will cheapen leading up to the election is this expectation of accelerated supply as we approach November.”

Municipals are returning 0.89% in September and 2.20% year-to-date per the Bloomberg Municipal Index. The high-yield index is at 0.80% so far this month and at 7.38% in 2024 while taxable munis are returning 1.41% in September and 5.28% year-to-date.

Treasuries have seen 1.53% returns in September and 2.29% in 2024 while corporates are at 1.67% in the black this month and 5.22% in 2024.

The front end of the tax-exempt curve has been the best performer since the summer, Foux noted. “It has already become relatively steep, but we think it could steepen further,” he said. The 5s10s index curve is just about 5 basis points away from its average in 2021; the 3s5s curve is about 10 basis points away from that average, Foux said.

“Although the IG yield curve could steepen a bit more, we think a better trade would be to invest in the parts of the market that have underperformed this move, such as pre-pay bonds with 4-7-year puts; alternatively, investors could extend a bit,” Foux said.

Despite week-to-date outperformance and steady inflows, J.P. Morgan strategists “maintain the view that the confluence of (i) expected weekly tax-exempt supply in the $11 billion to $13 billion range through October and (ii) a drop-off in reinvestment capital to around $6 billion/week could present the best opportunity to buy bonds of the year and possibly the rate cycle.”
