What was the name of the 1973–1974 stock-market collapse in Britain, one of the worst declines in the London Stock Exchange's history?

The 1973–1974 stock-market collapse in Britain is known as the 1973–1974 stock market crash.

The crash affected Britain and other major markets during a period of inflation, recession, political uncertainty, and energy disruption. The oil crisis that followed the 1973 Arab–Israeli War intensified economic pressure by sharply raising energy costs. British shares fell heavily as investors reassessed corporate profits and economic growth.

The Financial Times Ordinary Share Index, a major British market benchmark of the era, declined substantially during the downturn. The crisis was international rather than limited to one exchange, with U.S. and European markets also suffering steep losses.

It is sometimes confused with the 1987 Black Monday crash, which was a much shorter and more synchronized one-day shock. The 1973–1974 episode was a prolonged bear market shaped by macroeconomic forces, not only by a computerized trading event.
