IEA warns global oil refining system ‘stretched to the limit’ as Iran, Ukraine wars tighten market
The International Energy Agency warns the global oil refining system is stretched to the limit as conflicts in Iran and Ukraine tighten the market. A supply plunge of 5.7 million bpd is projected as the recovery of Gulf flows slips to 2027. While the IEA forecasts a sharp drop in oil demand, which has caused crude prices to fall, it suggests demand may need to decrease further if the war in Iran persists. The 2026 oil supply gap is expected to widen due to delayed Gulf flows.
