The MSRB is an independent, neutral source of municipal market data. It publishes a variety of municipal market statistics on and on its Electronic Municipal Market Access (EMMA) website, a free online database for municipal disclosures and trade data. 

The MSRB’s market statistics allow investors, issuers, municipal securities dealers, regulators, policymakers and others to review statistical trends and patterns for the municipal market.

What Statistics Are Available?
The MSRB publishes municipal market statistics on EMMA that reflect market-wide trading activity, new issuance levels and counts of continuing disclosure submissions.
