OPEC oil embargo (1973-1974)
Arab members of OPEC cut oil exports to the U.S. and other allies of Israel during the Yom Kippur War. Oil prices roughly quadrupled and Western economies slid into recession.
Gasoline rationing and long lines at pumps across the U.S. and Europe.
Energy security became a policy priority, driving fuel economy standards and diversification away from Middle East oil.
Like 1973, the Iran war is redrawing energy trade routes. This time the disruption comes from military attacks on physical infrastructure and shipping lanes, not embargo policy.
