Which U.S. bank failure helped trigger the Panic of 1857 and the resulting stock-market crash?

The failure of the Ohio Life Insurance and Trust Company helped trigger the Panic of 1857 and the resulting stock-market crash.

Ohio Life's New York City office suspended payments in August 1857 after fraud and embezzlement were discovered. The failure damaged confidence in banks, railroads, and other securities, contributing to a broader financial panic.

The crisis spread through the United States during a period of speculative railway expansion and falling commodity prices. The collapse of the New York branch of Ohio Life was especially important because it connected a regional institution to the nation's central financial market.

This panic is often confused with the later Civil War-era financial disturbances, but it began before the war. It also differed from the Panic of 1837, which had been associated with banking and land speculation earlier in the century.
