A large global oil surplus is masking regional tightness in crude and products markets, the IEA said today.
In its final Oil Market Report (OMR) for 2025, the IEA said oil prices have only fallen modestly despite the large supply overhang because of "diverging dynamics" across crude, NGLs and products in different regions.
This disconnect "notably reflects the high share of exports subject to sanctions (15pc of crude and 11pc of products), lengthening of supply routes and a tight refining system," it said.
The IEA's global oil supply and demand balances imply a 3mn b/d supply surplus in the fourth quarter of 2025, and more than 3.8mn b/d in 2026.
While oil on water has been rising and inventories building in China — global observed inventories rose by 1.4mn b/d in October, to a four-year high, and preliminary data show a further increase in November — there has been a notable absence of stock builds in key Atlantic basin pricing hubs, the IEA said, which is supporting prices and keeping crude futures in backwardation.
In products markets, refinery outages and a coming EU ban on imports of products derived from Russia crude has led to three-year high refining margins in November, the IEA said. This trend could continue in 2026 given "limited spare refining capacity outside of China."
The IEA said NGLs are increasingly comprising a large share of the overall liquids supply surplus, limiting the overhang's effect on crude prices.
The IEA upgraded its 2025 consumption growth forecast by 50,000 b/d to 830,000 b/d, based on an improving macroeconomic outlook and subsiding anxieties about trade tariffs. This would bring overall demand in 2025 to 103.92mn b/d. The IEA's first oil demand growth forecast for 2025, made in April 2024, had consumption growing by 1.15mn b/d.
The IEA also upgraded its 2026 demand growth forecast by 90,000 b/d to 860,000 b/d, which would bring total demand to 104.79mn b/d.
The IEA lowered its supply growth projection for 2025 by 100,000 b/d to 3.05mn b/d and for 2026 by 30,000 b/d to 2.45mn b/d. These were mainly because of disruptions to supplies in sanctioned countries such as Russia and Venezuela, the IEA said. This leaves supply forecast at 106.18mn b/d in 2025 and 108.63mn bd in 2026.
The IEA said Russia's crude output fell by 210,000 b/d in November to 9mn b/d, which is 500,000 b/d below its Opec+ target for the month. Russia's oil exports fell by about 400,000 b/d in November to 6.9mn b/d, "as buyers assessed the implications and risks associated with more stringent sanctions."
Venezuela's crude output fell by 150,000 b/d to 860,000 b/d "as sanctions and rising geopolitical tensions with the US limited the country's ability to market its oil," the IEA said.
