In 'Grotesque Billionaire Bonanza,' 41 Energy Tycoons Saw Fortunes Grow by $23.5 Billion Since Trump Launched Iran War

While much of the world is holding out hope that the US-Israeli war against Iran may finally be reaching an end amid news of a ceasefire agreement, the billionaire owners of some of the world's largest energy companies may not be so thrilled.

A handful of just 41 energy industry barons in Group of Seven (G7) countries collectively increased their wealth by $23.5 billion since the war was launched in late February, according to a report released by Oxfam International on Monday, as the leaders of the world's largest industrialized economies meet in France this week.

The oil shocks resulting from the war have caused fuel prices to spike dramatically, rippling inflation throughout the global economy and straining the pocketbooks of ordinary people around the world. One April report by the United Nations Development Program projected that, as a result of the conflict, an additional 32 million people would be pushed into poverty by the end of the year.

But between March 1 and May 18, owners of the largest oil and energy companies in Canada, France, Germany, Italy, Japan, the US, and the UK were adding $300 million on average per day to their collective wealth, Oxfam found through an analysis of Forbes’ Real-Time Billionaire List.

“Conflict devastates countries and costs countless lives, yet for some it is extraordinarily profitable,” said Oxfam International's executive director Amitabh Behar. “This is a brutal system that redistributes wealth upwards—from workers to shareholders, from the poorest to the richest, from those with the least power to those who already have far too much of it. While families are skipping meals and governments slash life-saving aid, we are witnessing a grotesque billionaire bonanza.”

While their accumulation of wealth cannot solely be attributed to the war, Oxfam noted that the Big Six oil companies—Chevron, Shell, BP, ConocoPhillips, Exxon, and TotalEnergies—are projected to grow their profits this year by 80% above the pre-war forecast, while the average large G7 company in the sample is projected to see just 8% growth.

Global billionaires saw their wealth increase on average by about 0.42% between March and mid-May. During the same period, G7 billionaires in the energy industry grew their riches by 9%, while those in oil and gas specifically became nearly 11% richer.

Oxfam notes that the Iran War has only widened the chasm between the rich and poor that was already gaping, in no small part thanks to nations in the G7.

While billionaire wealth has surged by nearly $10 trillion since 2020, G7 nations, mostly the US under President Donald Trump, have reduced aid to the poorest nations by $48 billion—equivalent to what billionaires in G7 countries accumulated for themselves in just nine days.

Meanwhile, since 2019, the last time France chaired a G7 summit, Oxfam estimated that 44 people per minute have come to be in need of humanitarian aid, based on 2025 data from the United Nations Office for the Coordination of Humanitarian Affairs.

Behar said that in order to secure the participation of the US in this week’s summit, French President Emmanuel Macron has chosen to table any discussions that might offend Trump—including the devastating cost of his war in Iran, Israel’s US-backed wars in Gaza and Lebanon, and anything to do with the climate crisis, which Trump has referred to as "a scam."

"Rather than defending collective governance, Macron and his peers are accommodating its destruction. This will have consequences measured in lives," he said.

Oxfam called for the "G6"—all the Group of Seven member countries, excluding the US—to create a comprehensive plan to protect people from the economic turmoil caused by the war and other spiraling global crises.

“The G6 can’t plead powerlessness,” Behar added. “They can cancel debt. They can tax windfall profits and extreme wealth... They can provide poorer countries with aid. Refusing to act simply because Washington will not join them is not diplomacy—it is cowardice. And it will only accelerate the G6’s slide into global irrelevance.”
