Welcome to the MSRB

Welcome to the Municipal Securities Rulemaking Board's (MSRB) web site. The MSRB makes rules regulating dealers who deal in municipal bonds, municipal notes, and other municipal securities. This web site contains useful information for municipal securities investors, dealers and the general public.

The Press Releases section also contains frequently updated material about the MSRB’s ongoing initiatives affecting municipal securities market participants and investors.

The MSRB collects official documents and trade data relating to municipal securities, and makes them available to the public for free on its Electronic Municipal Market Access (EMMA) website.
