The Municipal Securities Rulemaking Board (MSRB) was created by the U.S. Congress in 1975 to protect investors, municipal entities, and the public interest. It is a self-regulatory organization (SRO) subject to oversight by the U.S. Securities and Exchange Commission (SEC). The MSRB's mission is to establish and enforce rules for all securities firms, banks, and municipal advisors involved in the municipal securities market. It also operates the Electronic Municipal Market Access (EMMA®) website, which serves as the official repository for municipal market data and documents, providing free public access to enhance market transparency.
