Five months of US-Iran war fail to push oil past $100

Five months after the US-Iran war cut off a fifth of global crude supply through the Strait of Hormuz, Brent crude trades near $88 a barrel — roughly half the $150 that analysts forecast when fighting erupted in late February.

"The muted price response reflects a combination of demand destruction, alternative supply routes and strategic reserve releases that have blunted the war's impact on physical markets," said Tamas Varga, analyst at PVM Oil Associates.

Brent settled at $88.10 a barrel Friday, up 4.6% on the day and roughly 16% for the week, after the US struck Iranian bridges and an airport and Tehran retaliated against Kuwaiti power and desalination infrastructure. WTI crude closed at $82.49. Saudi Arabia has diverted more than 70% of its normal daily exports to the Red Sea port of Yanbu via the East-West Pipeline, with shipments averaging 4 million barrels a day — up from 973,000 a year earlier. US crude inventories fell 1.7 million barrels to 409.7 million in the week ended July 10, Energy Information Administration data show.

The gap between the war's theoretical supply shock and actual prices reveals a market that has found alternative pathways and absorbed demand destruction, but the buffer is thinning. If Iran follows through on threats to close the Red Sea — where Saudi exports now overwhelmingly flow — the price ceiling could break.

Three forces have kept a lid on prices that historical models would have predicted to surge past $100. Saudi Arabia's East-West Pipeline, with capacity of about 5 million barrels a day, has allowed the kingdom to bypass the Strait of Hormuz entirely, redirecting the vast majority of its exports to the Red Sea. The US and its allies have tapped strategic petroleum reserves, with the International Energy Agency coordinating releases that have added millions of barrels to the market. Higher prices themselves have destroyed demand — particularly in price-sensitive emerging economies across Asia and Africa, where import bills have forced consumption cuts.

The last time a conflict threatened a comparable share of global supply was the 1973 Arab oil embargo, when crude prices quadrupled within months. Today's market has structural buffers that did not exist five decades ago: US shale production that can respond to price signals within weeks, a more diversified supplier base including Brazil and Guyana, and a strategic reserve system designed for supply emergencies.

The equilibrium is fragile. Iran's Islamic Revolutionary Guard Corps Navy has stopped vessels attempting to transit the Strait of Hormuz without authorization, and ship-tracking data show no crossings via the US-backed alternate route. Retired Adm. James Stavridis, former NATO Supreme Allied Commander, warned Sunday that Iran or its proxies could eventually threaten the Suez Canal, which handles even more traffic than Hormuz. Two US service members were killed in Jordan by an Iranian strike over the weekend, crossing what President Donald Trump had described as a red line for resuming all-out war.

UBS commodity analyst Giovanni Staunovo said the oil market is tightening again, with repeated strikes on vessels transiting the Strait of Hormuz resulting in a measurable decline in tanker departures from the Gulf. If coordinated tanker targeting escalates or a sustained naval blockade materializes, Brent could approach $100 to $120 a barrel, according to scenario analysis by multiple commodity desks. A full closure of the Strait of Hormuz — removing 20% of global daily supply with no viable alternative routing — would cause severe dislocation that even strategic reserves could not fully offset.

For now, the market is pricing a partial restriction scenario. But each week of sustained hostilities erodes the buffers that have kept prices below triple digits.
