New Deal: U.S. President Franklin D. Roosevelt signs the Securities Exchange Act of 1934 into law, establishing the U.S. Securities and Exchange Commission.

The New Deal was a series of wide-reaching economic, social, and political reforms enacted by President Franklin D. Roosevelt in the United States between 1933 and 1938, in response to the Great Depression, which had started in 1929. Roosevelt introduced the phrase upon accepting the Democratic Party's presidential nomination in 1932 before winning the election in a landslide over incumbent Herbert Hoover, whose administration was viewed by many as doing too little to help those affected. Roosevelt believed that the depression was caused by inherent market instability and too little demand per the Keynesian model of economics and that massive government intervention was necessary to stabilize and rationalize the economy.

Franklin Delano Roosevelt, also known as FDR, was the 32nd president of the United States from 1933 until his death in 1945. He is the longest-serving U.S. president, and the only one to have served more than two terms. His first two terms were centered on combating the Great Depression, while his third and fourth saw him shift his focus to America's involvement in World War II.

The Securities Exchange Act of 1934 is a law governing the secondary trading of securities in the United States of America. A landmark piece of wide-ranging legislation, the Act of '34 and related statutes form the basis of regulation of the financial markets and their participants in the United States. The 1934 Act also established the Securities and Exchange Commission (SEC), the agency primarily responsible for enforcement of United States federal securities law.

The United States Securities and Exchange Commission (SEC) is an independent agency of the United States federal government, created in the aftermath of the Wall Street crash of 1929. Its primary purpose is to enforce laws against market manipulation.
