LONDON — Iran war oil losses have climbed past $50 billion after nearly 50 days of conflict and disruption in the Strait of Hormuz removed more than 500 million barrels of crude and condensate from the global market, according to analysts, Kpler data and Reuters calculations. The hit has endured even after Tehran signaled the chokepoint was open again, because production outages, damaged energy infrastructure, mine concerns and controlled shipping lanes are still slowing the return of normal flows, April 18, 2026.
Iran war oil losses keep rising even after Hormuz reopens
The scale of the shock helps explain why traders and policymakers remain uneasy. In its latest Strait of Hormuz brief, the International Energy Agency says the waterway carried an average 20 million barrels a day of crude oil and oil products in 2025, or about one-quarter of the world’s seaborne oil trade. That means even a partial disruption quickly becomes a global problem, not just a Gulf problem.
The physical damage is larger than the headline price swing suggests. The latest EIA global oil outlook says the de facto closure of Hormuz and regional shut-ins pushed Brent to an average of $103 a barrel in March, with daily prices briefly nearing $128 on April 2, and it now expects disruptions to weigh on balances into late 2026. In the near term, inventories have already drawn sharply and refiners, airlines and importers are still competing for replacement barrels.
Markets have started to remove some of the emergency premium, but only after a sharp and volatile run-up. Reuters reported Friday that Brent settled down 9.07% at $90.38 a barrel after Iran said commercial passage would remain open during the ceasefire period. Even so, that move looks more like a reset from panic pricing than a declaration that the supply system is fixed.
Why the supply shock is not over
Shipping through Hormuz is still not back to business as usual. A separate Reuters report said all commercial transits still require coordination with Iran’s Islamic Revolutionary Guard Corps, while mine risks in the traffic separation lanes remain unclear. That matters because delayed sailings, higher insurance costs and uncertain routing can keep squeezing supply even after a formal reopening announcement.
Some producers can reroute part of their exports, but others remain exposed. Saudi Arabia and the UAE have pipeline alternatives that can bypass part of Hormuz traffic, while Iraq, Kuwait, Qatar and Bahrain are more directly dependent on the strait. That uneven geography means the recovery is likely to arrive in patches, with some countries restoring volumes faster than others and some buyers paying up for safer or closer cargoes.
The broader consequence is a slower, costlier normalization. Even where barrels start moving again, damaged fields, refineries and LNG facilities will take time to repair. For consumers, that keeps the risk alive of higher fuel, freight and airline costs well after the market’s first relief rally.
Context over time
This crisis did not come out of nowhere. In a June 2025 EIA explainer, U.S. energy analysts warned that Hormuz handled more than one-quarter of global seaborne oil trade and that most volumes moving through the strait had no practical alternative route. That baseline now reads less like background and more like a roadmap for what the market is living through.
As the conflict deepened, Reuters reported on April 6 that geography was already splitting Gulf fortunes: Saudi Arabia and the UAE could cushion some of the blow through pipelines, while Iraq and Kuwait saw revenues collapse more sharply because they lacked meaningful bypass capacity.
Then, on April 7, Reuters noted that U.S. officials were warning fuel prices could keep rising for months even after Hormuz reopened, a reminder that reopening a chokepoint is not the same as restoring supply chains, inventories and confidence.
That is why the $50 billion figure matters. It is not just a snapshot of missing barrels. It is a measure of how quickly a regional war can fracture the world’s most important oil chokepoint, scramble trade flows and leave the global economy dealing with the aftershocks long after the first ceasefire headlines land.
