The first major U.S. stock-market crash associated with the railroad boom of the 1850s was called the Panic of 1857.
Railroads expanded rapidly during the 1850s, encouraging speculation in company shares, land, and related businesses. Investors also relied on unstable financial arrangements and expected continued economic growth. When confidence weakened, the failure of the Ohio Life Insurance and Trust Company in August 1857 became a major catalyst for panic.
The downturn spread through banks, railroads, merchants, and manufacturers. Securities prices fell, credit contracted, and unemployment rose. The crisis reached beyond the United States through international financial connections, although its effects varied by region and industry.
The Panic of 1857 is sometimes confused with later panics because the United States experienced repeated nineteenth-century financial crashes. The Panic of 1873 followed the collapse of Jay Cooke and Company, while the Panic of 1893 involved major railroad failures and banking distress.
