Since the Iran war began, oil prices have jumped and raised comparisons with the 1973 and 1979 shocks. Then, Arab oil producers imposed an embargo over Western support for Israel, sending prices soaring, prompting measures such as gasoline rationing and car‑free days in Germany. The question now: could a comparable crisis recur?
IEA chief Fatih Birol warned the conflict is “already the biggest threat to energy security in history,” estimating today’s oil shortfall at about 11 million barrels per day — larger than the roughly 5 million bpd shortfall in the 1970s and greater than losses seen after Russia’s 2022 invasion of Ukraine. He said the gas market is also facing a larger shortfall than in 2022.
Much of the current disruption stems from near closure of the Strait of Hormuz, a chokepoint for roughly a fifth of global oil and gas shipments, which has cut global oil flows by around 8%. Economists note the supply shock is sharper than in 1973–74, yet prices have not surged as violently. In the 1970s oil prices quadrupled and later tripled; now markets appear to expect the conflict to be shorter, which mutes price spikes. Oil at or above $100 is no longer unprecedented — similar levels have occurred during other crises (2007–08, 2011, post‑Ukraine invasion).
The nature of the shock differs. Today’s supply loss mainly comes from blockades and temporary shutdowns, not necessarily permanent damage to infrastructure. Still, conflict‑related strikes have hit more than 40 energy installations across nine Middle Eastern countries. Restoring some sites could take months or longer. Qatar warns attacks on its Ras Laffan LNG complex could cut supplies from that facility by about 17% for three to five years, though scholars point out even that outage would affect only a few percent of global gas supply.
Markets are also structurally different now. OPEC’s share of global crude has fallen from over half in 1973 to roughly 36% today. US production has risen sharply and has supplied much of the net addition to global output over recent decades. Global oil production has grown from under 60 million bpd in 1973 to nearly 94 million bpd by 2022, making the market larger and more diversified.
Countries have accumulated strategic and commercial reserves to cushion shocks. IEA‑reported reserves stood at about 8.2 billion barrels early this year — the highest since February 2021. IEA members agreed to release 400 million barrels from emergency stocks to address immediate shortfalls; that, along with other measures, is estimated to have reduced the crude shortfall from about 11 million bpd to around 8 million bpd. The US has temporarily relaxed enforcement on some Russian and Iranian cargoes already at sea to ease supply strains.
Analysts estimate OECD reserves could cover lost Strait of Hormuz shipments for roughly nine months; China’s reserves might cover its Middle East imports for about seven months. But the critical unknown is the war’s duration and whether more installations or shipping routes will be hit. If the Strait of Hormuz remains closed and damage mounts, the risk of a severe, prolonged energy crisis grows.
Economic effects are already emerging: short‑term inflationary pressure and likely cutbacks in oil consumption that will slow industrial output. Governments have not broadly imposed rationing yet, though some places are taking local measures — for example Pakistan shifted a major cricket tournament to a watch‑from‑home format to conserve energy.
In short, while the current supply disruption is large and comparable or even larger in scale than the 1970s shock, several factors — market expectations of a shorter conflict, greater supply diversification, substantial reserves and emergency releases — have so far prevented a repeat of the dramatic price spikes and prolonged stagflation of the 1970s. The trajectory depends chiefly on how long the conflict lasts and whether further infrastructure or shipping disruptions occur.
