MSRB Adds Tradeweb AAA Municipal Curve To Municipal Market Yield Curves On Emma

The Municipal Securities Rulemaking Board (MSRB) today expanded the availability of yield curves and indices on its free Electronic Municipal Market Access (EMMA®) website with the addition of the Tradeweb AAA Municipal Curve.

“Offering the Tradeweb AAA Municipal Curve for free on EMMA is an important enhancement to market transparency,” said MSRB Chief Market Structure Officer John Bagley. “MSRB is proud to provide another source of hourly municipal yield information that can help investors, issuers and other market participants make more informed and timely decisions.”

The Tradeweb AAA Municipal Curve, the foundation for its Ai-Price model for municipal bonds, is constructed by selecting AAA-rated general obligation and certain revenue bonds that meet specific criteria metrics. It is updated hourly by combining public MSRB data with data from Tradeweb’s electronic municipal bond trading platform and leveraging proprietary machine learning and data science technologies to adjust the curves intra-day.
