About MSRB

The Municipal Securities Rulemaking Board was established in 1975 by Congress to develop rules for broker-dealers and banks that underwrite, trade and sell municipal securities – bonds, notes and other securities issued by states, cities, and counties or their agencies to help finance public projects or for other public purposes. The MSRB promotes investor protection through prudent regulation and expert market leadership.

MSRB Rulemaking

MSRB rules are intended, first and foremost, to protect investors and the public interest, to prevent fraudulent and manipulative acts and practices and to promote just and equitable principles of trade. Among the most important of the MSRB’s investor protection rules address fair dealing obligations, suitability of recommendations, fair pricing of transactions, and disclosures of material information to investors. These rules require broker-dealers and banks to observe the highest professional standards in their activities and relationships with their customers. The MSRB also establishes rules intended to promote a free, efficient and open market in municipal securities.

The MSRB has authority to make rules regulating the municipal securities activities of broker-dealers and banks only. The MSRB does not have authority over issuers of municipal securities, investors or other market participants.

Cooperation with Other Federal Regulators

The MSRB’s activities are subject to the oversight of the Securities and Exchange Commission. In addition, Congress has delegated the responsibilities for examining broker-dealers and banks for compliance with MSRB rules, and for enforcing such rules, to various other federal regulators – the Financial Industry Regulatory Authority for broker-dealers, and the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, and the United States Department of the Treasury's Office of the Comptroller of the Currency and Office of Thrift Supervision for banks.
