A run on the stock of the Knickerbocker Trust Company sets events in motion that will spark the Panic of 1907.

The Knickerbocker Trust was a bank based in New York City that was, at one time, among the largest banks in the United States. It was a central player in the Panic of 1907.

The Panic of 1907, also known as the 1907 Bankers' Panic or Knickerbocker Crisis, was a financial crisis that took place in the United States over a three-week period starting in mid-October, when the New York Stock Exchange suddenly fell almost 50% from its peak the previous year. The panic occurred during a time of economic recession, and there were numerous runs affecting banks and trust companies. The 1907 panic eventually spread throughout the nation when many state and local banks and businesses entered bankruptcy. The primary causes of the run included a retraction of market liquidity by a number of New York City banks and a loss of confidence among depositors, exacerbated by unregulated side bets at bucket shops.
