Municipals were weaker Tuesday as short-end munis continued to sell off, U.S. Treasuries were weaker 10 years and in and equities were mixed.

Triple-A muni yields rose nine to 12 basis points in one-year, further inverting the curve on the short end. Heavy secondary trading on the short end moved one-year triple-A yields as much as nine basis points higher than the two- and five-year maturities, depending on the scale.

The one- to five-year inversion of five basis points has only happened 10 times during the past 41 years, noted Refinitiv MMD.

“The muni story of the moment is the now firmly implanted inversion and flattening in the first five years of the curve — with volatility usually reserved for equity markets,” said Kim Olsan, senior vice president of municipal bond trading at FHN Financial.

Short muni-UST ratios rose with the two- and three-year ratios, reaching near 60%. The five-year was at 64%, the 10-year at 81% and the 30-year at 96%, according to Refinitiv MMD’s 3 p.m. read. ICE Data Services had the five at 64%, the 10 at 84% and the 30 at 93% at a 3:30 p.m. read.

Olsan noted that “ultra-heavy selling combined with a ratio- and yield-adjusting theme in 2023 and 2024 has set up an unusual dynamic for the market.”

The UST curve has been inverted for much of the summer leading to ultra rich short muni to UST ratios.

Inversions haven’t happened that often in recent history, but she said “given ratios that fell below 50% there was some expectation of a correction.”

“A byproduct of the short yield spike is the re-emergence of short paper moving behind 2% again — more of a psychological than material aspect in that this yield range still is only about parity on a TEY basis with short USTs,” she added.

Trade data has shown one- to three-year volume rose 68% from prior sessions as a result of heavy bid list activity.

“High-quality commitments appear to be the preferred option, with rate volatility alone not needing to be complicated by credit concerns,” she said.

“Single-A and AMT-subject bonds are being discounted by a larger margin — Philadelphia Airport bonds due in 2023 (A2/A- and subject to AMT) were bought +63/AAA MMD after seeing compressed pricing early in the year closer to +40/AAA MMD,” Olsan said.

Several issuers are selling longer-dated debt into residual reinvestment demand while the market navigates an evolving curve slope, she said, pointing to Miami-Dade County, Florida’s AA-rated transit bonds (due 2043-2052), Long Island, New York’s A-rated electric bonds (maximum maturity 2044), and New York City’s GOs with a 2046 final maturity schedule.

“There is currently an implied extension opportunity into 25 years from the intermediate range, with a yield pickup of about 60 basis points,” according to Olsan.

“An aversion to front-end risks is reasonable, with the Fed continuing to message the likelihood of more hikes incoming,” said Matt Fabian, a partner at Municipal Market Analytics.

SIFMA is around 60% of 30-year nominal triple-A tax-exempt. Since the start of the pandemic, SIFMA has averaged 16% of the 30-year.

“It’s no wonder that the market has seen an uptick in floating-rate issuance attached to fixed payor swaps for non-governmental issuers (& banks are still paying just 0.13% to savings depositors),” he said. “Which, for the fixed-rate market, offsets a bit of longer-maturity issuance and helps keep long yields lower.”

This, he said, is in addition to “the trend MMA showed last week of the most (+$9.2B) net direct lending by banks to muni issuers” in a decade in the second quarter of the year.

“In other words, bank demand is robust and further flattening a curve that is already facing excess demand from scarcity, wavering inflation indicators, and still-strong credit performance,” Fabian said.

If fund flows turn more positive, “things could become even more extreme; this fact is likely steering automatic and model-based allocators away from tax-exempts,” he said.

“But where, in prior markets, this would have precipitated some gains taking, the opposite has been true — selling volumes last week fell to their lowest non-holiday total since February,” Fabian noted.
