Big Oil's Q2 2026 Windfall: A $35–40 Billion Profit Surge Fueled by War

ExxonMobil signaled in a July 7 SEC filing that its Q2 earnings would be roughly $5 billion higher than Q1, with analysts projecting adjusted net income of approximately $15.7–$15.9 billion . A separate report stated the company posted $7.1 billion in GAAP earnings on $84.0 billion in revenue . The discrepancy between the analyst estimate and the GAAP figure reflects differences in earnings metrics — analysts focus on adjusted (non-GAAP) results that exclude one-time items and certain timing effects.

Chevron is "poised to beat" Q2 profit estimates on surging crude revenue and improved refining margins, according to UBS Securities, which lifted its Q2 EPS estimate to $5.70 from $3.82 . Chevron will report on July 31 .

Shell and BP had not published Q2 results in the available sources. Neither company had released final figures as of the latest sourced articles (July 23, 2026). Equinor's Q2 results were also not found in the retrieved data .

What Drove the Surge: War, a Chokepoint, and Refining Margins

Three interconnected factors drove the profit surge:

1. The U.S.-Israeli war with Iran, which began on February 28, 2026. By late March, Brent crude had risen over 50% since the onset of the conflict, according to a Reuters analyst survey . The World Bank described the subsequent oil market disruption as the largest in history .

2. The near-total closure of the Strait of Hormuz. Iran declared the strait closed to all vessels in June, warning that any ship attempting to navigate through would face attack . Roughly 20% of global oil and LNG transits the waterway . J.P. Morgan warned that crude production from Iraq and Kuwait could be halted within days, estimating potential supply losses of up to 4.7 million barrels per day .

3. Sharply improved refining margins. Both Exxon and TotalEnergies cited this as a second major profit driver alongside higher crude prices, as fuel markets tightened worldwide .

Brent Crude: From $100 to $126 and Back to $72

Brent crude performance in Q2 2026 was nothing short of extraordinary:

• March 8: Brent surpassed $100/barrel for the first time in four years .
• Late April: The benchmark peaked at over $126/barrel — the highest since 2022 .
• March 2026: Recorded the largest-ever monthly oil price increase, according to the Wikipedia article on the Strait of Hormuz crisis .
• Late June: As flows through the strait showed signs of recovery, Brent erased its war premium and fell back to around $72/barrel .

This dramatic volatility created ideal conditions for oil trading desks, which thrive on price swings.

Why European Majors with Trading Operations Excelled

TotalEnergies' performance illustrates the advantage held by European majors with large petroleum trading operations. The company explicitly cited "oil trading results" as a key driver, alongside higher oil prices and stronger refining margins . Its downstream results and cash flow "increased sharply" compared to Q1 .

The broader trend was visible even in Q1 2026: five European majors (BP, Repsol, TotalEnergies, Eni, and Equinor) posted combined profits of $21.7 billion, up 43% year-on-year, driven by the same war-induced volatility .

The Missing Piece: Political Scrutiny

The available sources contain no specific articles detailing the Trump administration's response to these profits, such as potential windfall profit taxes or political actions targeting Big Oil ahead of the November 2026 midterm elections. The broader context — that these massive profits occur during a war the U.S. is actively involved in and just months before a major election — strongly suggests political sensitivity, but no concrete administration statements or actions were captured in the sourced data.

Bottom Line

The five Western supermajors are on track for a combined Q2 2026 profit of an estimated $35–40 billion or more, with TotalEnergies (up 68%) and ExxonMobil (potentially tripling Q1 adjusted earnings) leading the way. The U.S.-Israeli war with Iran and the near-total closure of the Strait of Hormuz were the primary drivers, creating an oil market shock that the World Bank called "the largest in history." European majors with large trading desks — particularly TotalEnergies — benefitted disproportionately from the volatility. But Shell, BP, and Chevron had not yet reported final figures as of late July, meaning the full picture is still incomplete. Political scrutiny from the Trump administration, while widely expected given the election timing, was not documented in the available sources.
