Wars are now hitting more than 43% of the world's oil supply

More than 43% of the world’s oil now comes from countries caught in wars, attacks and export curbs. Countries hit by the disruptions produced about 45 million barrels of oil a day in 2025, according to Reuters calculations based on IEA data.

The figure, based on 2025 production, underlines how this year’s disruptions have grown beyond a single flashpoint and eclipsed previous energy crises.
