The 1973 Oil Embargo

Why the embargo happened

Egypt and Syria attacked Israel on 6 October 1973. By then the oil market had already shifted in producers' favour: US crude output had peaked in 1970, American imports were rising fast, and spare production capacity sat almost entirely in the Middle East. The dollar had also been devalued in 1971 and 1973, which cut the real value of oil revenue priced in dollars.

Arab members of OPEC used both levers they controlled, price and volume. Until 1973, posted prices had been negotiated with the international oil companies. From October, producers set them on their own.

Timeline: October 1973 to July 1974

How prices went from $3 to $12

The posted price was a tax-reference price rather than a freely traded market price, which is why the jump came in two administrative steps: the 70% rise on 16 October and the move to $11.65 from 1 January 1974. On annual averages, the Energy Institute's long-run series (Arabian Light at Ras Tanura) shows crude at $2.48 in 1972, $3.29 in 1973 and $11.58 in 1974. Prices in auctions and on the small spot market briefly traded well above the posted level during the winter of panic buying.

Adjusted with the US consumer price index to August 2026 dollars, the move was from about $21 to about $84 per barrel. The real increase was as large as the nominal one, because it happened within three months. For a long-run comparison, see inflation-adjusted oil prices.

Impact on Western economies

The physical shortfall was smaller than the price shock. Arab producers cut output by 5% to 10% at first, and Saudi and Kuwaiti production fell by about 30% at the low point, while Iraq raised output. Oil was rerouted, so embargoed countries kept receiving some crude. What changed was cost and confidence.

• Fuel shortages. US price controls and allocation rules made the shortage visible at the pump. Stations rationed sales (some to 10 gallons per customer) and queues formed in the winter of 1973–74.
• Inflation. Wholesale prices of industrial commodities were already rising at more than 10% a year in mid-1973. The oil shock added to this and fed the "stagflation" of the mid-1970s.
• Recession. The US economy entered a recession in late 1973 that lasted until 1975, and most other industrial economies also contracted.
• A transfer of income. Oil exporters' revenues multiplied, and the recycling of "petrodollars" through Western banks shaped international finance for the rest of the decade.

The lasting legacy

Most of today's energy security system was built in response to 1973:

• The International Energy Agency, proposed by US Secretary of State Henry Kissinger, was created in 1974. Its members must hold emergency stocks. It has coordinated six collective stock releases, the most recent of 400 million barrels on 11 March 2026.
• The US Strategic Petroleum Reserve was authorised by the Energy Policy and Conservation Act of 1975.
• Fuel economy standards and a national 55 mph speed limit cut US oil use per mile driven.
• New supply from the North Sea, Alaska and Mexico became economic at the new price level, which eventually eroded OPEC's market share in the 1980s.

The embargo also established the idea that a few producers controlling spare capacity can set prices. That idea still drives OPEC+ policy and the market's sensitivity to the Strait of Hormuz.

1973 compared with the 2026 Hormuz shock

In 1973 the supply cut was a political decision that producers could reverse, and they did within five months. In 2026, physical flows through the Strait of Hormuz fell to under 10% of normal after the conflict began on 28 February, according to the IEA. The 2026 disruption was larger in volume, but the world now holds large emergency stocks and has more varied supply. A 1973-style quadrupling from Brent's pre-war level of about $71 would have meant roughly $285 per barrel. In fact the EIA Brent spot price peaked at $138.21 on 7 April 2026 (see oil prices in 2026).
