- The International Energy Agency’s May oil market report warns that the Middle East war has shut in more than 14 million barrels per day of crude, creating the largest oil supply disruption in history.
- Global supply is set to fall 3.9 million bpd in 2026, leaving supply 1.78 million bpd below demand; even with high prices eroding consumption by 420,000 bpd, the market will remain undersupplied through Q3 2026.
- The IEA estimates cumulative supply losses will surpass one billion barrels, with a 246 million‑barrel drawdown in March and April alone.
The International Energy Agency’s latest oil market report paints a stark picture of an energy system rocked by conflict.
The war in the Middle East, which closed the Strait of Hormuz and triggered repeated attacks on shipping, has removed more than 14 million barrels per day of supply – an unprecedented disruption. Overall, the IEA expects global oil supply to shrink by 3.9 million bpd in 2026, reversing previous predictions of a surplus.
With demand still projected to grow modestly, the agency now forecasts a supply deficit of 1.78 million bpd, meaning supply will be insufficient to meet consumption.
High prices are already dampening consumption. The IEA estimates that demand will decline by 420,000 bpd compared with earlier expectations as consumers and industry curb usage. Yet even with this drop, the market will remain undersupplied through at least the third quarter of 2026.
Cumulative supply losses since the conflict began exceed one billion barrels, and inventories were drawn down by 246 million barrels in March and April alone. The IEA warns that stockpiles could fall even further if the war drags on and supply remains constrained.
Historic supply shock
The supply crunch has already sent Brent crude above $100 per barrel and fuelled inflation, straining households and businesses. For import‑dependent countries like the UK, the report underscores the danger of relying on global oil markets.
Analysts argue that the shock will accelerate the push toward electrification, renewables and alternative fuels. Governments may also consider building strategic reserves or entering into long‑term supply contracts to shield consumers from volatility.
The IEA’s analysis diverges from OPEC’s more optimistic demand projections, but both organisations agree that geopolitical risk is now the key driver of oil markets. If the conflict eases and the Strait of Hormuz reopens, some supply could return; however, the IEA notes that even then it may take months to fully restore production and shipping.
For now, energy‑intensive industries and policymakers must prepare for tight markets, high prices and potential rationing. The report reinforces the case for diversifying energy supply – investing in domestic renewables, electrifying transport and heat, and improving efficiency – to reduce exposure to future supply shocks.
