Reuters: War Affected Countries Produced 43 Percent of World Oil in 2025

According to Reuters calculations based on International Energy Agency data, countries at war or directly affected by conflict produced about 45 million barrels of oil per day in 2025, more than 43 percent of global supply. Reuters cited the Iran war with the United States and Israel that began about six months ago, alongside the Russia Ukraine war and export restrictions in Libya and Venezuela, as the main drivers. The report estimates current disruption to Persian Gulf oil export flows at 5 to 7 million barrels per day, and says more than 10 percent of the world's oil refining capacity has been taken offline due to the conflicts in the Persian Gulf and Ukraine.
