In July 1857, railroad stock values reached their highest point, but on August 11, the failure of N. H. Wolfe and Company, New York City's oldest flour and grain firm, shook investor confidence. This event triggered a gradual market sell-off that continued through late August, contributing to the financial instability that culminated in the Panic of 1857. The crisis led to business failures, declines in the railroad industry, and widespread unemployment, exposing vulnerabilities in the U.S. economy and its dependence on gold reserves.
