IEA deepens 2026 global oil-demand decline forecast to 2.5 million b/d
In its September Oil Market Report, the International Energy Agency revised its 2026 global oil-demand forecast downward by 940,000 barrels per day from its August estimate and now projects a 2.5 million-barrel-per-day decline, the largest annual drop since the 2020 pandemic. The IEA said losses would be concentrated in middle distillates and petrochemical feedstocks, particularly in Asia, as Middle East supply disruptions and higher prices weigh on consumption.
This is a quantified, forward-looking IEA revision rather than market-price commentary: the 2026 global oil-demand outlook worsened by 940,000 barrels per day to a projected 2.5 million-barrel-per-day decline, with losses concentrated in middle distillates and petrochemical feedstocks. The magnitude and breadth of the revision create material implications for oil producers, refiners, airlines, and feedstock-sensitive chemical companies. The development remains distinct from the related supply-outlook update because its central fact is the demand forecast revision; the timestamp is anchored to the reporting post because the exact IEA release time is not explicitly stated.
The IEA has cut its forecast for 2026 global oil demand by -940,000 barrels per day, now expecting consumption to fall -2.5 million barrels per day, the largest annual decline since the 2020 pandemic.
The downgrade comes as the Iran War disrupts oil supplies and forces consumers to adjust to tighter availability, with the biggest impact expected on diesel and other middle distillates such as jet fuel and heating oil.
