This bill reforms how the Municipal Securities Rulemaking Board (MSRB) is structured and operates. The MSRB is an organization that sets rules for how brokers, dealers, and advisors handle municipal securities—basically bonds and other financial products issued by cities, states, and other local governments.

Right now, the board's makeup isn't clearly defined in law. This bill fixes that by specifying exactly who should serve on the 15-member board. The key requirement is that a majority must be people who work in the securities industry (brokers, dealers, and advisors), but the board must also include public representatives—people who don't work in the industry. These public members must include someone representing investors, someone representing municipal governments, and a regular member of the public. This balance ensures the board isn't entirely controlled by the industry it regulates.

The bill also clarifies the board's powers to create rules about how securities professionals conduct business, sets up a process for appointing board members with staggered three-year terms, and requires the Securities and Exchange Commission (SEC) to set a maximum compensation level for board members. Additionally, the bill emphasizes that the board should work closely with the SEC and other regulators, meet regularly to share information, and establish clear data standards for information submitted to the board. The goal is to make the board more transparent, better balanced between industry and public interests, and more coordinated with other financial regulators.
