What was the 1973–1974 stock-market crash called after the collapse of the postwar economic boom?

The stock-market collapse during the breakdown of the postwar economic boom is called the 1973–1974 stock-market crash.

The downturn affected major markets, including the United States and the United Kingdom. In the United States, the S&P 500 fell deeply from its January 1973 peak to its October 1974 low. The crash accompanied inflation, recession, high interest rates, and energy-market disruption.

The 1973 oil crisis intensified the shock after Arab members of OPEC imposed an oil embargo on countries supporting Israel during the Yom Kippur War. Oil prices rose sharply, but the market crash had several causes, including monetary tightening, weak economic growth, and excessive confidence in large “Nifty Fifty” companies.

The event is sometimes reduced to an oil-price crash, but oil was one part of a broader stagflationary crisis. The term “Nifty Fifty” refers to popular large-company shares, not to the official name of the market collapse.
