1973 Arab Oil Embargo

The 1973 Arab Oil Embargo was imposed in October 1973 by OAPEC, led by Saudi Arabia, in retaliation for Western support of Israel during the Yom Kippur War. OAPEC cut production and banned exports to the United States and key allies. Oil prices quadrupled from around $3 to $12 per barrel within months, removing approximately 5 million Barrels Per Day from global supply.

The embargo is the primary historical yardstick for the 2026 Iran conflict. The IEA declared it "the largest supply disruption in the history of the global oil market," with Gulf production down at least 10 million barrels per day — double the 1973 scale. An emergency release of 400 million barrels from strategic reserves failed to cap prices within hours.

In 1973 the embargo triggered Stagflation across the West: inflation and recession that central banks struggled to contain. Today, Brent Crude above $100 per barrel is pushing US diesel past $5 per gallon, and economists warn that $140 per barrel tips the world into recession. The 1973 precedent shapes every policy response: reserve releases and IEA coordination trace their institutional logic to those five months.
