Global Energy Crisis: Iran War and Ukraine Fallout Rivals 1970s Oil Shocks

The global energy crisis caused by the war in Iran and the fallout from the Ukraine conflict is equivalent to the combined force of the twin oil shocks of the 1970s, according to the head of the International Energy Agency (IEA).

Fatih Birol, the IEA's executive director, warned that the growing fallout could be seriously compounded by interruptions to the 'vital arteries of the global economy', including petrochemicals, fertilisers, sulphur, and helium.

The crisis, which started with bombings against the regime in Tehran on 28 February, already represents the loss of 11m barrels of oil per day and about 140 bcm of gas. This is comparable to the losses seen in the 1973 and 1979 oil crises, which saw a loss of about 5m barrels of oil per day each, and Russia's 2022 invasion of Ukraine, which removed about 75bn cubic metres (bcm) of natural gas from international markets.

Birol said that at least 40 energy assets in the Gulf region had been severely or very severely damaged, so even an end to the conflict would not immediately restore energy supply. He also noted that the Asia Pacific region had been badly affected by the closure of the Strait of Hormuz, through which about 20% of the world's oil supply is transported.

The IEA has taken emergency measures, including the release of 400m barrels of oil from strategic reserves, the largest emergency measure in its history. Birol said he is consulting world leaders about another possible release of emergency oil supply, noting that the initial move was only 20% of overall stocks.
