The Federal Reserve is likely to keep its target rate unchanged this week, but falling oil prices may be taking some pressure off the inflation outlook just as the market heads into Kevin Warsh’s first meeting as chair. If that continues, Treasury and municipal yields could begin to fall again after spending much of the spring rangebound at higher levels. For municipal investors, that matters because lower long-term yields could reinforce a demand story that has already defined much of 2026.

Oil prices moved lower Monday as markets reacted to a reported U.S.-Iran framework that would reopen the Strait of Hormuz and reduce one of the most important recent sources of inflation pressure. The details are still incomplete, and the agreement is not fully public yet. But if the framework holds and the strait reopens as expected, one of the main near-term arguments for higher yields loses some force.
For municipal investors, lower yields could add to an already powerful demand story. Demand has been the defining municipal bond market story of 2026, and we made that point at the end of May. Since then, another $4.3 billion has flowed into municipal mutual funds over three weeks, including a $625 million inflow just last week, according to Lipper.
If lower energy prices help pull yields down again, demand for municipals could strengthen further. Supply has been strong enough to meet that demand so far, and issuance through May was running ahead of last year at a $47 billion monthly average (compared to $46 billion in 2025) even as markets adjusted to the risk that rates could stay higher for longer.
