The excess profits generated by war have once again made major oil companies a target of attack.

On June 29, 2026, U.S. President Donald Trump posted a final ultimatum on Truth Social, addressing all U.S. gas station retailers: reduce gasoline prices to approximately $2.50 per gallon—or face 'serious problems.' He warned of zero tolerance for so-called 'illegal price gouging' and escalated an action campaign ongoing for several weeks, aimed at forcing energy companies to pass wholesale price reductions on to consumers. At the time, international crude oil prices fluctuated between $60 and $68 per barrel—a level considered relatively low by recent historical standards. Trump’s argument was straightforward: if raw materials are cheap, then finished products should be too. This was not an isolated outburst. The June 29 statement followed a similar declaration issued by Trump on June 24; prior to that, on June 25, he had already publicly accused oil companies of exploiting consumers by failing to pass on lower wholesale costs. In addition to fierce rhetoric, Trump’s June 29 post carried implicit—perhaps even explicit—threats. He ordered the Department of Justice to investigate oil companies, specifically examining the gap between the fuel prices paid by retailers and those actually charged to consumers at gas stations. California also received special attention in this post. Trump pointed out that the state’s fuel tax policy imposed a heavy burden on drivers. As Trump intensified scrutiny of gasoline prices, major oil companies stood poised to record unprecedented profits. Soaring international oil prices inevitably generate substantial excess profits for oil-producing and exporting countries—and for oil companies—a pattern consistent with over 160 years of global petroleum industry history. Yet, while the Trump administration grappled with persistently high domestic fuel prices, highly profitable major oil companies found themselves squarely in Trump’s crosshairs. Industry expert Tsvetana Paraskova detailed this situation in an article published on the website OilPrice.com on July 6, 2026. Paraskova noted that major oil companies were expecting unexpected second-quarter profits: ExxonMobil and Chevron’s earnings were projected to more than triple, driven by the disruption in the Strait of Hormuz—which sent crude prices surging and boosted refining margins. Although industry insiders acknowledged that retail gasoline prices tend to lag behind declines in crude prices, this sharp profit surge intensified political pressure: President Trump demanded gasoline prices fall to $2.25–$2.50 per gallon and launched investigations into potential price manipulation. Oil companies countered by citing market cyclicality, attributing the current gasoline price increases primarily to low fuel inventories, improved refining economics, and supply-chain delays—not to profiteering. With the Strait of Hormuz closed, crude oil prices surged to their highest level in four years, and oil majors anticipated outsized gains in Q2. ExxonMobil and Chevron’s profits for the April–June quarter were projected to triple compared to Q1, as the most severe supply disruption in oil market history impeded Middle Eastern oil exports, triggered a crude price spike and heightened volatility, and depleted oil inventories—including those in the United States.

Geopolitical conflict fuels energy windfalls and economic fragmentation: A deep macroeconomic analysis of oil-price dynamics, oil-company excess profits, and global macroeconomic impacts amid the U.S.–Iran war.

Introduction At the end of February 2026, the United States and Israel jointly launched large-scale airstrikes against Iran, triggering full-blown military conflict among the U.S., Israel, and Iran. Global energy lifeline—the Strait of Hormuz—saw disrupted shipping, sending international crude markets into violent turbulence. Geopolitical risk premiums pushed oil prices steadily higher. U.S. oil giants ExxonMobil and Chevron capitalized on the soaring prices to secure historic excess profits—some firms’ profits reaching 12 times year-on-year levels. On August 3 (local time), U.S. President Donald Trump publicly expressed dissatisfaction with oil companies’ windfall profits at the White House: first, condemning them for seizing war-related gains and refusing to pass savings on to end consumers, and mandating that oil majors slash domestic refined-fuel retail prices; second, bluntly forecasting that once the U.S. fully resolves the Iranian issue and regional geopolitical tensions subside, global oil prices will plunge precipitously. This energy-price storm—ignited by armed conflict—has long transcended the scope of commodity markets, forming a complete economic transmission chain: Middle East geopolitical disruption → volatile international oil prices → U.S. oil companies reaping war dividends → domestic inflation rebounding and household consumption under pressure → the Federal Reserve caught in a monetary-policy dilemma → executive branch pressuring energy giants → global industrial-chain cost restructuring. Researchers from the Ameriga Global Economic Research Institute (Shanghai), a subsidiary of Ameriga Global (Shanghai) Economic Development Co., Ltd., observed in earlier tracking analyses that this round of oil-price fluctuations is far more than a singular energy-market event—it will reshape global cross-border supply chains, regional trade layouts, digital-industry cost structures, and the pace of new-energy development. Several domestic industrial research institutions have likewise conducted complementary analyses across supply-chain, digital-technology, and industrial-manufacturing dimensions. This article offers a comprehensive, in-depth economic analysis across six dimensions: crude-oil pricing logic; deconstruction of U.S. oil-company profitability; macroeconomic shocks to the U.S.; global inflation and trade patterns; expectations-based博弈 (game-theoretic) dynamics of oil-price rises and falls; and the future trajectory of the energy industry—clarifying the underlying operational logic of energy economics amid geopolitical warfare, unpacking the dual economic and political motivations behind Trump’s pressure on oil firms, and forecasting the profound implications of the conflict’s trajectory for oil prices and the global economy. Chapter One: U.S.–Iran Conflict Reshapes Global Crude Supply Architecture—Geopolitical Premium Emerges as Core Price Driver 1.1 Strait of Hormuz: The Achilles’ Heel of the Global Oil Supply Chain and the Fundamental Catalyst Behind This Oil-Price Surge The Strait of Hormuz controls the sole maritime outlet from the Persian Gulf, handling roughly 30% of seaborne crude oil shipments and about 20% of total global crude consumption. Core Middle Eastern producers—including Saudi Arabia, Iraq, Kuwait, and Iran—rely heavily on this waterway for crude exports, earning it the moniker 'the world’s oil valve.' Following the U.S.–Israel airstrikes against Iran at the end of February 2026, Iran swiftly retaliated—deploying drones and missiles to harass passing tankers and laying maritime blockade devices—slashing the strait’s navigation efficiency by half. A large number of crude carriers were forced to reroute, causing sharp spikes in maritime transport costs and insurance premiums. Markets formed persistent fears of supply disruption—not due to actual crude output cuts, but rather to sustained logistical paralysis. This fear constituted the core ignition point for the oil-price surge. Before the conflict erupted, WTI U.S. crude benchmark prices held steady in the $65–$68/barrel range, while Brent crude hovered near $72/barrel. Within one month of the outbreak, Brent crude hit an intraday high of $126/barrel, and WTI breached $100/barrel—representing a short-term surge exceeding 54%, the largest staged gain in crude prices in nearly four years. Even after markets gradually absorbed some of the extreme panic, prices experienced only partial retracement: as of early August, both benchmark contracts remained over 20% above pre-war levels, while U.S. domestic retail gasoline prices rose nearly 40%. According to data from the American Automobile Association (AAA), the national average gasoline price soared from $2.98/gallon before the conflict to $4.10/gallon—fuel-cost inflation directly squeezing American households’ daily expenditures.
