How did the government regulate banks and the stock market in the first Roosevelt administration

During the recession, the Glass-Stegall Act regulated banks not allowing them to cross state lines, perform investment banking, and other restrictions. Then in the early 1980s the regulations were slowly chipped away until 1999 when Glass-Stegall was completely repealed.

The SEC was created during the depression to regulate the stock market. Eventually by 2000, it became more of an arm of wall street than a real regulator.
