The International Energy Agency’s (IEA) Oil Market Report (June 2026) highlights a global oil market transitioning from tight supply conditions toward a potential surplus later in the decade, driven by recovering Middle East output, shifting demand patterns, and expanding non-OPEC supply.
In the short term, the report notes that oil markets remain relatively tight as production in parts of the Middle East is still recovering following earlier disruptions to flows through the Strait of Hormuz. While the reopening of the waterway is gradually restoring exports, full production recovery remains uneven, keeping supply constrained in 2026.
Looking further ahead, the IEA expects a significant increase in global supply capacity as Middle Eastern output rebounds and non-OPEC producers continue to expand. However, demand growth is weaker than historical trends, creating conditions for a growing imbalance. The agency warns that by 2027, the market could shift into a sizeable surplus unless demand strengthens or supply is adjusted.
The report also highlights regional volatility: Russian production has been affected by geopolitical tensions and infrastructure attacks, while global inventories are expected to fluctuate as markets rebalance.
The oil market is currently tight due to geopolitical disruptions, but is expected to shift toward oversupply in the coming years as supply rebounds faster than demand.
