Despite the expected rate cut, analysts will be watching the Federal Open Market Committee's actions for other reasons.

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.

The White House has appealed a D.C. District Court ruling allowing Federal Reserve Gov. Lisa Cook to remain on the Fed board pending the outcome of her challenge to President Trump's moves to fire her.

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 Senate Banking Committee voted 13-11 to favorably recommend Stephen Miran's nomination for the Federal Reserve Board to the full Senate.

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.

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.

Stephen Miran will take unpaid leave from and might seek to return to President Trump's Council of Economic Advisers, he said, raising conflict of interest questions in his nomination hearing for a seat on the Federal Reserve Board.

The Justice Department has opened a criminal investigation into Federal Reserve Gov. Lisa Cook and allegations of mortgage fraud, allegations that spurred President Trump to terminate her position on the Fed Board last week. Cook is challenging the president's authority to remove her in court.

Federal Reserve Gov. Lisa Cook filed a lawsuit in federal court Thursday morning seeking an injunction against President Trump's "illegal attempt" to remove her from the Fed board. The suit claims Trump has not demonstrated "cause" for her removal under the Fed statute.

President Trump posted a letter on social media addressed to Federal Reserve Gov. Lisa Cook, informing her that he was terminating her due to allegations of mortgage fraud. The move is likely to tee up an unprecedented legal fight over the Fed's independence.

Munis underperformed a UST rally, which had everything to do with Powell's speech at the Jackson Hole symposium and future Fed action, said Cooper Howard, a fixed income strategist at Charles Schwab.

The latest inflation report — the producer price index — threw a monkey wrench into expectations for a big rate cut next month, according to some economists, may put into question any easing in September.

"The combination of stronger core and softer headline readings has left some traders struggling for direction," said Daniela Sabin Hathorn, senior market analyst at Capital.com. "There is a reason to be both bullish and bearish depending on which CPI reading you wish to focus on."

Trump advisers are impressed with Waller's willingness to move on policy based on forecasting, rather than current data, and his deep knowledge of the Fed system as a whole, the people said.

Miran, if nominated and approved by the Senate, is only expected to serve a term that expires in January, according to the person, who requested anonymity to discuss internal deliberations.

The Minneapolis Fed chief added that tariffs still represent a significant uncertainty and it's unclear what impact they'll have on inflation.

"I asked him just last night, is this something you want?" Trump said Tuesday in an interview with CNBC. Bessent's response was, "Nope, I want to stay where I am," he said.
