Tradeweb created a model that examines outstanding municipal securities, both tax-exempts and taxables, and it looks for similarities in bond features, such as maturities, call dates, use of proceeds and coupon structures.

BofA Global Research strategists said they believe peak muni yields in this Fed tightening cycle were attained in October 2023 and "the bull market for munis is underway." 

The municipal dashboard solves three challenges: bond linkage, pricing and spread aggregation.

The process of turning the data into a usable form takes time and can be compounded by the difficulty of extracting what data there is and the format used by issuers in documents, like official statements, disclosures and other financials.

"Demand is firming up. Interest rates have moved off the recent highs. Intermediate muni yields are about 50 basis points off from those highs," said Stephen Shutz, head of tax-exempt fixed income and a portfolio manager at Brown Advisory.

Buying technology can be a relatively safe bet, especially if it comes from an established brand, and it comes with support, maintenance and expertise from vendors. Internally building it allows for exclusivity and a potential competitive advantage.

"Everyone is reevaluating and taking a breather after the numbers [on Tuesday]," a New York trader said.

Munis yields fell nine to 12 basis points, depending on the curve, but underperformed larger gains along the UST curve. Large new-issues began pricing.

November "continues to be off to a strong start as yields have fallen an average of 34 basis points across the curve since the start of the month," said Jason Wong, vice president of municipals at AmeriVet Securities.

"As with most fast rallies there are sessions when the market pauses to assess where fair value should play out," said Kim Olsan, senior vice president of municipal bond trading at FHN Financial.
