Which 1973–1974 bear market followed the oil crisis and helped end the postwar stock-market boom?

The 1973–1974 bear market that followed the oil crisis and helped end the postwar stock-market boom was the 1973–1974 stock-market crash.

The decline began amid inflation, monetary tightening, political uncertainty, and economic weakness. The 1973 oil crisis intensified those pressures after the Organization of Arab Petroleum Exporting Countries imposed an embargo on countries supporting Israel during the Yom Kippur War.

The Dow Jones Industrial Average fell about 45 percent from its January 1973 high to its December 1974 low. In the United Kingdom, the FT 30 index fell even more sharply. The period combined falling share prices with high inflation and weak economic growth, a condition often called stagflation.

The crash was not caused by the oil embargo alone. It reflected several overlapping shocks, including the collapse of the Bretton Woods monetary system, inflation, recession, and the Watergate crisis in the United States.
