Which British trading bank collapsed in 1866, helping trigger a major Victorian stock-market panic?

The British trading bank that collapsed in 1866, helping trigger a major Victorian stock-market panic, was Overend, Gurney and Company.

Overend, Gurney and Company suspended payment on May 10, 1866. The firm had evolved from a respected bill broker into a bank that made riskier investments, including financing railways and other ventures. When confidence weakened, it could not meet demands for cash and failed despite its earlier reputation.

The collapse triggered the Panic of 1866, which spread through London’s financial markets. Credit became scarce, companies failed, and investors sold securities. The Bank of England eventually used its lender-of-last-resort authority by extending credit under emergency conditions, helping prevent an even broader breakdown.

The episode is often linked to the development of modern central-bank crisis management. It also illustrates the danger of confusing an established name with a sound balance sheet: Overend, Gurney’s prestige encouraged confidence even as its business model changed. The panic occurred during a period of rapid railway expansion and financial innovation, when failures could travel quickly through credit networks.
