Secondary bond market

The new-issue calendar is at $15.637 billion and boasts four mega deals.

Earlier Thursday, the market was "chugging along, doing OK, just kind of nothing, in between slight strength to modest upticks, but the narrative changed when that bank news came out. The market really ran pretty quickly," said Chris Brigati, managing director and CIO at SWBC.

"In theory at least, municipal yields should be able to stabilize here; levels remain attractive for pure income buyers while more sustainable constructive fund inflows are just enough to speak for rising issuance in the absence of meaningful reinvestment," said Matt Fabian, president of Municipal Market Analytics.

Municipals are impacted by fluctuating supply and demand influences more than most other markets, said Jeff Timlin, a partner at Sage Advisory.

Carving up risk allows buyers who normally shy away from junk bonds to buy the pooled securities.

The large issuance of munis this year, up 12.9% year-to-date, "disadvantaged" the asset class compared to other U.S. fixed income assets for a majority of 2025, said Pat Haskell, head of the municipal bond group at BlackRock.
