The Iran War's Other Winners: Big Oil Cashes In While Consumers Pay the Bill
By Abbas Sadeghian, Ph.D.
Wars produce obvious winners and losers on the battlefield, but they also produce economic winners thousands of miles away from the fighting. The Iran war is increasingly demonstrating this uncomfortable reality. While civilians face insecurity, governments spend billions on military operations, consumers confront higher energy costs, and Iran struggles to sell its own petroleum, some of the world's largest multinational oil companies have found themselves operating in an extraordinarily profitable environment. ExxonMobil, Chevron, BP, Shell and TotalEnergies did not start this war, and there is no evidence that they determine its course. Nevertheless, the disruption of Persian Gulf energy markets has helped create precisely the combination of higher oil prices, wider refining margins and extreme market volatility from which large, geographically diversified energy corporations can benefit.
The Numbers Tell the Story
The financial results reported by the major oil companies are striking. ExxonMobil reported approximately $14.5 billion in earnings for the second quarter of 2026, compared with roughly $4.2 billion in the preceding quarter. Chevron reported approximately $12 billion in adjusted quarterly earnings, its highest quarterly profit in years. Shell's adjusted earnings reached approximately $9.8 billion, more than twice the level reported a year earlier, while BP reported approximately $5.7 billion in underlying replacement-cost profit compared with about $2.4 billion in the second quarter of 2025. TotalEnergies has also benefited from the dramatically altered international energy environment. These companies have different operations and exposures, and some have simultaneously experienced disruptions to their Middle Eastern businesses, but the broader pattern is difficult to ignore: the Iran war has helped create extraordinarily favorable conditions for major energy companies possessing production and refining capacity outside the immediate conflict zone.
The Geography of Profit
The apparent contradiction becomes easier to understand when geography is considered. An oil company heavily dependent upon production inside the Persian Gulf can suffer when shipping routes become dangerous, facilities are damaged or exports are interrupted. A global corporation, however, can lose some production in one region while simultaneously receiving dramatically higher prices for oil produced elsewhere. ExxonMobil, for example, has enormous production operations outside the Persian Gulf, including major assets in the Permian Basin and Guyana. When instability in the Gulf removes or threatens barrels of oil from the world market, the barrels Exxon produces safely elsewhere become more valuable.
Chevron enjoys a similar advantage. Its large American production base allows it to sell oil produced thousands of miles from the fighting at prices influenced by events in the Persian Gulf. This illustrates one of the peculiar characteristics of the international petroleum market: a bomb does not have to fall anywhere near a Texas oil field for the economic consequences of that explosion to increase the value of the oil coming from that field. When a major producing region becomes unstable, the geopolitical risk premium becomes incorporated into the international price of petroleum, benefiting producers whose own operations remain comparatively secure.
The Strait of Hormuz Changes the Equation
The Strait of Hormuz has always been one of the most important geographical chokepoints in the global economy. An enormous quantity of petroleum and liquefied natural gas normally passes through this narrow waterway connecting the Persian Gulf with the Arabian Sea. When war threatens that traffic, the market does not wait for every tanker to stop moving before reacting. Insurance costs increase, shipping becomes more expensive, traders begin calculating the possibility of future shortages, and buyers compete more aggressively for alternative supplies.
This means that even partial disruption can have effects far beyond Iran. Iraq, Qatar, Kuwait, Bahrain, Saudi Arabia and the United Arab Emirates all depend to varying degrees upon the security of Gulf transportation routes. Every additional military confrontation near these routes increases uncertainty. That uncertainty itself has economic value. For producers outside the region, it can translate into higher selling prices. For traders, it creates price differences that can be exploited. For refiners with secure access to crude oil, it can increase the value of the gasoline, diesel and other petroleum products they manufacture.
Refining May Be the Bigger Story
Much of the public discussion understandably concentrates on crude-oil prices, but refining may be one of the most important parts of the story. Crude oil sitting in a storage tank does not fuel an automobile, truck or airplane. It must be transported to a refinery and converted into gasoline, diesel, jet fuel and other usable products. When refining capacity is damaged or taken offline, the consequences can therefore be felt even when crude oil remains available somewhere else in the world.
This helps explain why downstream operations have become so profitable for some multinational oil companies. Chevron's downstream earnings rose dramatically during the second quarter, while ExxonMobil also recorded exceptionally strong downstream results. BP reported substantially stronger refining margins as part of the explanation for its improved financial performance. When refineries in or near a conflict region cannot operate normally, functioning refineries elsewhere become more valuable. A shortage of refining capacity can therefore generate large profits independently of the increase in the underlying price of crude oil.
