What was the official name of the U.S. market regulator created after the 1929 stock-market crash?

The official name of the U.S. market regulator created after the 1929 stock-market crash was the Securities and Exchange Commission.

Congress established the SEC in 1934 through the Securities Exchange Act. The agency was designed to restore confidence in securities markets after the crash and the financial abuses exposed during the Great Depression. Its responsibilities include enforcing federal securities laws, overseeing exchanges and brokers, and requiring important public-company information to be disclosed to investors.

The SEC is often confused with the Federal Reserve. The Federal Reserve manages monetary policy and supervises parts of the banking system, whereas the SEC focuses primarily on securities markets and investor protection. The agency followed the Securities Act of 1933, which addressed the public offering of securities and preceded the SEC’s creation.
