New York stock market crash triggers the Panic of 1873

Background. Prior to the crash, the US economy experienced overexpansion driven by railroad construction and speculative investments. The crisis was exacerbated by deflation, the demonetization of silver, and ripples from the Franco-Prussian War, creating a fragile financial environment prone to panic. By September 1873, the US economy was in crisis, with deflation causing banking panics and destabilizing business investment.

Causes. The immediate trigger was the failure of Jay Cooke & Company, a major banking establishment, which could not market millions in Northern Pacific Railway bonds. Reports circulated that the firm's credit had become nearly worthless just as it sought a government loan. This failure caused equities to plummet on the New York Stock Exchange, initiating a chain reaction of bank runs.

Impact. The crash signaled the arrival of the Panic of 1873 to American shores, leading to a contraction lasting from October 1873 to March 1879. In the United States, 18,000 businesses went bankrupt, including 89 railroads. The event is often cited as the beginning of the Long Depression, though historians debate the exact duration and underlying causes.
