Energy markets verge on disaster amid Iran war

TL;DR

The story at a glance

The Economist warns that global energy markets teeter on disaster amid the Iran war, with oil traders oddly optimistic despite volatility. Iran's Strait of Hormuz blockade traps huge volumes of crude and LNG, forcing shutdowns and refinery cuts, even as brief reopenings spark price swings. This is reported now as Iran's April 17th claim of safe passage reversed hours later with a tanker attack, amid failed ceasefires and US blockades.[[1]](https://www.economist.com/finance-and-economics/2026/04/21/global-energy-markets-are-on-the-verge-of-a-disaster)[[2]](https://www.reuters.com/business/energy/how-iran-war-oil-gas-supply-shock-compares-with-past-disruptions-2026-04-22)

Key points

Details and context

The Iran war, starting late February 2026 with US-Israeli strikes, prompted Iran's retaliation: closing the Strait of Hormuz (15-20% of world oil, similar LNG share) and hitting Gulf infrastructure. This stranded 550m barrels, dropped Middle East output by 7-10m bpd or more, and spiked prices—Brent up nearly 50% at peaks to $110+ before swings.[[1]](https://www.economist.com/finance-and-economics/2026/04/21/global-energy-markets-are-on-the-verge-of-a-disaster)[[2]](https://www.reuters.com/business/energy/how-iran-war-oil-gas-supply-shock-compares-with-past-disruptions-2026-04-22)

Brief ceasefires and Iran's "open" claims led to 10-12% price drops (to $89-90), but attacks, US blockades, and military denials reversed them. Mines, sunken ships, and insurance halts slow recovery; Gulf states lack bypass routes fully, forcing production cuts.[[3]](https://www.economist.com/finance-and-economics/2026/04/17/hormuz-is-apparently-unblocked-energy-markets-remain-a-mess)[[6]](https://www.economist.com/finance-and-economics/2026/04/08/the-third-gulf-war-will-scar-energy-markets-for-a-long-time-yet)

Asia hit hardest by refinery shutdowns; shortages spread to Europe, prompting EU measures. Unlike past crises, this hits oil, gas, refined products, fertilizers together, amid deeper trade links.[[2]](https://www.reuters.com/business/energy/how-iran-war-oil-gas-supply-shock-compares-with-past-disruptions-2026-04-22)

What changed

Before late February 2026, Strait of Hormuz carried 15-20% of global oil and LNG with routine traffic. Now, near-total blockade since US-Israeli strikes traps 550m barrels, slashes output, and spikes prices despite brief lulls. Disruptions began February 28th with war onset.

FAQ

Q: Why have oil prices stayed below March peaks despite the crisis?

A: Traders remain sunny amid brief Hormuz reopenings and ceasefire hopes, but attacks and mistrust cap gains; Brent hovers $20 under late-March highs around $110.[[1]](https://www.economist.com/finance-and-economics/2026/04/21/global-energy-markets-are-on-the-verge-of-a-disaster)

Q: What traps oil in the Gulf?

A: Iran's Hormuz closure holds 550m barrels of crude; US blockade adds pressure, while mines, attacks, and missing ships deter tankers.[[1]](https://www.economist.com/finance-and-economics/2026/04/21/global-energy-markets-are-on-the-verge-of-a-disaster)

Q: How long until markets normalize?

A: Months of tightness even if reopened, due to mistrust, sunk ships, and refinery cuts; facility repairs may take years.[[3]](https://www.economist.com/finance-and-economics/2026/04/17/hormuz-is-apparently-unblocked-energy-markets-remain-a-mess)

Q: Is this worse than past energy shocks?

A: Yes, per IEA—biggest ever by daily output lost, hitting multiple fuels unlike prior oil-only crises.[[2]](https://www.reuters.com/business/energy/how-iran-war-oil-gas-supply-shock-compares-with-past-disruptions-2026-04-22)
