Iran has shut the Strait of Hormuz again after a tentative U.S.-Iran ceasefire collapsed, reviving fears of a second global oil shock after brief vessel traffic resumed last month.
15 million barrels per day were knocked out when the war began, but a worst-case crisis was delayed by a 400 million-barrel IEA reserve release, higher output from producers including the U.S., and conservation steps in more than 100 countries.
Those buffers are fading: emergency stockpiles are nearing depletion, the U.S. strategic reserve is heavily drawn down, and China has resumed buying crude for refineries after months of restraint.
Prices have eased from early peaks, yet shortages and inflation have already spread beyond crude—from fertilizer and gasoline to helium, sulfur and semiconductors—while U.S. gasoline inventories sit near a 10-year low.
Analysts say if Hormuz stays closed, prices will need to rise much higher to crush inelastic demand, raising the risk of broader economic disruption later this year.

The world's emergency oil is gone. As the Strait of Hormuz closes again, what is the world's plan B?
With military strikes escalating and diplomacy failing, is the Hormuz energy crisis about to ignite a wider global war?
The 2026 Strait of Hormuz Blockade: Oil Supply Disruption, Inflation Surge, and Geopolitical Realignment
Overview
The Strait of Hormuz is a vital maritime chokepoint, enabling the flow of over a quarter of the world’s crude oil and a fifth of global LNG, as well as other key commodities. As of July 2026, it stands at the center of renewed U.S.-Iran tensions, with both sides unwilling to compromise. Iran’s ability to disrupt this narrow waterway has made it a major obstacle in peace talks, threatening global trade and energy security. The crisis highlights how deeply the world depends on this strait, and how its vulnerability fuels economic and geopolitical instability.
