Municipal Securities Rulemaking Board (MSRB)
Also known as: MSRB
The Municipal Securities Rulemaking Board (MSRB) is the self-regulatory organization that writes the rules governing broker-dealers and banks that underwrite and trade municipal securities. It creates rules but does not enforce them — enforcement falls to FINRA, the SEC, and bank regulators.
The Municipal Securities Rulemaking Board (MSRB) is a self-regulatory organization (SRO) created by Congress in 1975 to regulate the municipal securities market. It writes the rules that govern securities firms and banks engaged in underwriting, trading, and selling municipal bonds and notes, as well as municipal advisors. Its stated mission is to protect investors, issuers, and the public interest by promoting a fair and efficient municipal market.
The MSRB's defining quirk is that it makes rules but has no enforcement power. Its rules are enforced by other regulators: FINRA and the SEC for securities firms, and federal bank regulators for banks that deal in municipals. Equally important, the MSRB regulates dealers and municipal advisors — not issuers. States, cities, and other municipalities are largely exempt from registration requirements, so the MSRB cannot force an issuer to disclose anything.
MSRB rules cover areas like fair dealing, suitability, political contributions (Rule G-37, aimed at pay-to-play abuses), gifts and gratuities, advertising, and uniform practices for confirming and settling municipal trades. The MSRB also operates EMMA (Electronic Municipal Market Access), the free public website for municipal bond disclosures, official statements, and trade prices.
Securities exams lean on the MSRB's structure heavily. The SIE, Series 6, Series 7, and Series 10 exams all expect you to know that the MSRB writes rules for municipal dealers, that it does not enforce its own rules, and that it has no authority over municipal issuers.
Key takeaways
- The MSRB is the SRO that writes rules for broker-dealers, banks, and municipal advisors in the municipal securities market.
- It has no enforcement authority — FINRA, the SEC, and bank regulators enforce MSRB rules.
- The MSRB regulates dealers, not municipal issuers, who are largely exempt from registration requirements.
- The MSRB operates EMMA, the public portal for municipal disclosures and trade data.
- The SIE, Series 6, Series 7, and Series 10 exams routinely test the MSRB's rulemaking-without-enforcement structure.
