The 1907 financial panic that prompted calls for U.S. banking reform was the Panic of 1907.
The crisis began after a failed attempt to corner the stock of United Copper Company. Depositors then withdrew money from banks and trust companies connected to the speculators, and fear spread through the financial system. The New York Stock Exchange fell sharply, while several financial institutions faced runs and liquidity shortages.
J. P. Morgan helped organize private rescue efforts, persuading banks and wealthy financiers to provide funds and stabilize threatened institutions. The episode showed how heavily the United States depended on private coordination because it had no modern central bank.
The panic contributed directly to the creation of the Federal Reserve System in 1913. It is distinct from the Panic of 1893, an earlier banking crisis, and from the 1929 Wall Street Crash, which began a much broader economic contraction.
