IEA warns of global oil deficit through 2026 as Iran conflict hits output

Oil market in deficit

The IEA forecasts imply that supply will come in 1.78 million bpd below total demand in 2026, erasing a 410,000 bpd surplus projected in last month's report and a close to four million bpd surplus in its December report.

"Our latest supply and demand estimates imply that the market will remain severely undersupplied through the end of 3Q26, even assuming the conflict ends by early June," the Paris-based agency said, adding that the second-quarter deficit will be as stark as six million bpd.

The IEA's base-case forecast is for a gradual resumption of traffic through the strait from the third quarter onwards, it said, which could see the market return to a "modest surplus" by the fourth quarter, allowing depleted stocks to begin to rebuild.
