Municipals saw a sharp correction Wednesday, with yields rising double-digits as the asset class played catch up to U.S. Treasuries after recent outperformance led to too-rich ratios. Deals in the primary repriced to higher yields as a result.

Muni yields rose five to 18 basis points, depending on the scale, pushing the 10-year above 3% for the first time since early July. UST yields rose one to five basis points.

Muni-UST ratios rose. The two-year ratio Wednesday was at 67%, the three-year at 67%, the five-year at 68%, the 10-year at 72% and the 30-year at 87%, according to Refinitiv Municipal Market Data’s 3 p.m. EST read. ICE Data Services had the two-year at 68%, the three-year at 67%, the five-year at 67%, the 10-year at 72% and the 30-year at 85% at 3:30 p.m.

USTs have been on a “one-way trade up in yield” for several weeks, though munis have ignored that a bit, including last week, said Kim Olsan, a senior fixed income portfolio manager at NewSquare Capital.

Ideally, there would have been some trades to support moves along the way last week instead of muni yields being cut double digits on Wednesday, she said.

The rout, Olsan said, “is all about correcting ratios.”

“If you look at the broad metrics, bid wanted count going up, dealer inventory going up week after week, money market balances going up … [meaning] some amount of money is hanging in cash and not getting invested, then supply at its level, it’s all bearish for performance,” Olsan added.

Other macroeconomic and political factors have rattled markets overall. Treasury rates “have spiked sharply as a Republican election win looks more likely, raising concerns about deficit spending and inflation,” said James Pruskowski, chief investment officer at 16Rock Asset Management.

This shift has “stirred uncertainty, softening secondary liquidity in the muni market,” he said.

The increased probability of a Republican victory has led to an acceleration in supply as “issuers rush to secure funding amid policy uncertainty,” Pruskowski said.

“Coming off rich muni-Treasury ratios, the market has swiftly repriced,” he said. “With now cheaper benchmark yields and wider credit spreads, fresh capital is flowing in, and a strong bottoming opportunity looks to be emerging.”

“It is not particularly surprising to see tax-exempt rates reset higher in sympathy with earlier moves in the UST market, particularly given expected heavy supply this week and next, and amid near annual lows in reinvestment capital,” said J.P. Morgan strategists, led by Peter DeGroot, in a report.

A continued selloff in USTs will put some more pressure on muni yields to “go a bit higher,” as ratios have been in fair to rich territory and the flurry of deals coming to market will need to price according to more attractive levels, said Jeff Timlin, a partner at Sage Advisory.

The Investment Company Institute reported $1.524 billion of inflows into municipal bond mutual funds for the week ending Oct. 16 after $2.013 billion of inflows the week prior.
