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 MSRB often posts changes, amendments, and additions to rules as well as notices about our services in the What's New section.
