Step-by-step explanation:
The 3 governmental bodies that regulate how securities are sold and how business in the securities markets is conducted are the SEC (Securities and Exchange Commission), FINRA (Financial Industry Regulatory Authority), and FRB (Federal Reserve Board).
The SEC is an independent agency of the federal government and plays a crucial role in protecting investors, maintaining fair and efficient markets, and facilitating capital formation. It regulates the securities industry, enforces securities laws, and oversees stock exchanges and broker-dealers.
FINRA is a self-regulatory organization authorized by Congress to protect investors and ensure market integrity. It oversees broker-dealer firms and licensed securities professionals, establishes rules and regulations for the securities industry, and enforces compliance with these rules.
The FRB is the central banking system of the United States. While it primarily focuses on monetary policy and banking supervision, it also plays a role in regulating the securities markets, particularly in maintaining financial stability.
