IEA Oil Market Report - Executive Summary

Global Demand

  • Global oil demand growth is projected at 930 kb/d in 2026 , up from 850 kb/d in 2025, reflecting economic normalization following tariffs and lower prices in the previous year.
  • Growth will come mainly from non-OECD countries , while gasoline demand continues to slow, partially offset by the increase in petrochemicals.

Global Offer

  • Global production fell 350 kb/d in December 2025 to 107.4 mb/d , 1.6 mb/d below the record in September.
  • The production cuts in Kazakhstan and some Middle Eastern OPEC countries were partially offset by Russia's strong rebound.
  • Global supply is projected to increase by 2.5 mb/d in 2026 (after +3 mb/d in 2025), with non-OPEC+ producers contributing 1.3 mb/d to this expansion.

Refineries and Inventories

  • Global refining processes increased 2 mb/da to 85.7 mb/d in December 2025, before the seasonal maintenance of 1Q26.
  • Refining margins fell in December, especially in Europe, due to reduced profitability of middle distillates.
  • Observed global inventories increased by 75.3 mb in November , with a cumulative total of 470 mb in 2025 , reflecting oversupply, higher Chinese stockpiles and US gas liquids.

Prices

  • Brent crude averaged $62.64/b in December , falling to its lowest level since 2021 ($60.07/b).
  • In early January 2026, geopolitical tensions in Iran and Venezuela caused a spike from $6/ba to ~$66/b, which then moderated to $64/b.
  • Despite these fluctuations, prices remain $16/b below a year ago , reflecting the accumulated global surplus.

Geopolitical Factors

  • Venezuela : Exports fall from 880 kb/d in December to ~300 kb/d due to US sanctions.
  • Iran : Crude oil shipments fell 350 kb/d from October to November/December, with volumes accumulating at sea.
  • Russia : Production and exports rebounded (+550 kb/d in December) despite attacks on infrastructure.
  • Kazakhstan : Supplies limited due to attacks on infrastructure and transport.

Outlook 2026

  • The global oversupply , driven by non-OPEC+ producers (USA, Brazil, Guyana, Canada, Argentina), and excess inventories, creates a buffer sufficient to absorb the projected demand of 930 kb/d.

If no major disruptions occur and OPEC+ maintains its production policy, global supply is expected to increase by an additional 2.5 mb/d in 2026 , keeping prices relatively stable despite geopolitical tensions.
