The escalation of the 2026 Iran conflict has delivered the largest oil supply shock in decades. With the Strait of Hormuz partially blocked, attacks on Gulf infrastructure, and millions of barrels of daily production taken offline, Brent crude prices surged more than 50% at their peak, briefly topping $120 per barrel. Yet despite the windfall that higher prices usually bring to the industry, not every major oil company is celebrating.
European majors such as BP, Shell, and TotalEnergies have largely benefited from the volatility. BP more than doubled its first-quarter profits, describing the period as “exceptional.” Shell beat analyst expectations, while TotalEnergies posted roughly 30% profit growth. These companies have captured much of the upside from elevated oil prices and tighter refining margins.
In contrast, American giants ExxonMobil and Chevron reported sharp declines in Q1 2026 earnings. Exxon’s net income fell approximately 45% year-on-year to $4.2 billion — one of its weakest quarters in recent years. Chevron saw profits drop by more than a third. The divergence has puzzled some observers who expected all upstream-heavy players to thrive in a high-price environment.
The reasons lie in geography, operational exposure, and financial timing. Both Exxon and Chevron maintain significant interests in the Middle East. Exxon’s production was hit particularly hard, with roughly 15% of its worldwide output affected by shutdowns, delivery disruptions, and higher operating costs. Even companies with more diversified portfolios felt the sting when physical volumes could not reach markets.
Hedging strategies added another layer of complexity. Oil companies routinely use derivatives to manage price risk. When prices spiked suddenly due to the conflict, certain hedges generated substantial losses on paper. Exxon, for instance, cited billions in missed offsets tied to delayed sales. These accounting effects are expected to reverse in coming quarters as the underlying oil is eventually sold at higher realized prices, but they weighed heavily on Q1 results.
Other factors played a role too. Strong performance in non-Middle East assets — such as Exxon’s developments in Guyana and the Permian Basin — provided some cushion. Still, the immediate operational pain outweighed the headline benefit of higher benchmark prices for the most exposed players. Independent producers and companies with minimal Gulf exposure, including ConocoPhillips, generally fared better.
The broader picture remains mixed. U.S. shale producers, Brazilian and African exporters, and certain refiners have gained from tight product markets and rerouted supply chains. Many analysts still project solid full-year results for the majors if oil prices remain elevated through the rest of 2026. However, the conflict has highlighted a crucial truth: in a real supply shock, location and logistics matter as much as — or more than — the price on the screen.
As ceasefire talks continue and shipping through the Strait of Hormuz remains fragile, the industry’s winners and losers could shift again in the months ahead. For now, the 2026 Iran war has proven that even in an oil boom, not every giant prospers equally.
