"Anytime you get a market off 50 basis points in a day, the bulk of that move is being driven by fast money and the fast money is in ETFs," said Michael Pietronico, CEO at Miller Tabak Asset Management.

Yields rose significantly for the fourth time this week as the aftereffects of President Donald Trump's tariffs continue to plague the financial markets.

"The discussion about policies regarding tariffs will drive performance in bonds over the next three to six months," said Michael Pietronico, CEO of Miller Tabak Asset Management.

Triple-A muni yields plummeted up to 50 basis points Thursday in a dramatic reversal from the week's earlier collapse. Speaking live at The Bond Buyer's Texas Public Finance event, market leaders painted a picture of extreme volatility, impaired liquidity, and an uncertain path forward.

"The equity market is looking at this more positively, but bonds are still thinking, 'Well, these tariffs still have to be resolved,'" said Kim Olsan, a senior fixed income portfolio manager at NewSquare Capital.

Municipal AAA yield curves were cut up to another 42 basis points, depending on the curve, as of noon, pushing yields to multi-year highs and long-end muni to UST ratios above 100%. Muni yields have risen up to nearly 100 basis points in spots since the bond market rout began.

A $125 million bond sale by the Indianapolis Local Public Improvement Bond Bank for Indianapolis public transit operator IndyGo is on day-to-day status.

Weakness in the muni market has been partly amplified by ETF selling; high-grade yields rose more than 60 basis points on parts of the curve over two sessions.

A new S&P upgrade and one last year from Moody's burnish the Colorado Statewide Bridge and Tunnel Enterprise ahead of a $212 million revenue bond deal.

"The changing momentum on what the market is looking for on tariffs and the volatility in the equity market is spilling over into the Treasury market, and munis can only fight the Treasury market for so long," said Pat Luby, head of municipal strategy at CreditSights.
