OPEC oil embargo (1973-1974)
Arab oil producers cut exports to the U.S. and its allies. Crude prices roughly quadrupled within months, driving broad inflation across Western economies.
Consumers faced soaring energy and food prices; economic growth stalled while inflation climbed.
The shock fed entrenched inflation expectations and wage-price spirals, contributing to the stagflation of the late 1970s.
The RBNZ's current dilemma mirrors the embargo: a supply-driven fuel shock that risks becoming embedded in wages and pricing behavior if central banks wait too long.
