Global oil markets are expected to remain highly volatile after the International Energy Agency (IEA) warned that oil supply will fall significantly below demand in 2026 due to disruptions caused by the Iran conflict. Restricted tanker movement through the Strait of Hormuz and production outages across Gulf producers have created an unprecedented supply shock, with over 14 million barrels per day shut in. The IEA now projects a supply deficit of 1.78 million bpd, reversing earlier surplus expectations. Although weakening economic activity and high prices are reducing demand, the sharp fall in supply is likely to keep crude oil prices elevated globally.

Key Highlights

•   IEA projects global oil supply deficit of 1.78 million bpd in 2026.

•   Iran conflict disrupts Gulf production and Hormuz tanker traffic.

•  Over 14 million bpd of oil output reportedly shut in.

•   Global supply forecast revised sharply lower due to war impact.

•   High oil prices and weaker growth expected to reduce demand.

Crude oil prices remain strongly supported after the International Energy Agency (IEA) warned that global oil supply is expected to fall significantly below demand in 2026 due to escalating disruptions linked to the Iran conflict. The sharp deterioration in supply conditions has intensified concerns over global energy security and triggered renewed bullish sentiment across oil markets.

Supporting the price rally, the IEA reported that restrictions on tanker movement through the Strait of Hormuz have severely disrupted exports from Gulf producers. The agency estimates that cumulative supply losses have already crossed 1 billion barrels, with more than 14 million barrels per day of production currently shut in. As a result, the IEA now forecasts a supply deficit of 1.78 million bpd for 2026, a major reversal from its earlier expectation of a supply surplus.

The agency also sharply revised its global supply outlook, projecting oil production to decline by nearly 3.9 million bpd this year due to war-related disruptions. The Middle East remains a crucial energy-producing region, and prolonged instability around key shipping routes continues to create uncertainty for global crude availability.

On the demand side, the IEA expects oil consumption to decline by 420,000 bpd as higher energy prices and slowing economic growth weaken fuel demand globally. Elevated crude prices are contributing to demand destruction, particularly in energy-sensitive sectors and emerging economies.

Despite weaker consumption expectations, the magnitude of supply disruptions is likely to dominate market sentiment. Traders are also closely monitoring the possibility of gradual normalization in Hormuz shipping activity during the second half of the year.

Overall, severe Middle East supply disruptions are expected to keep crude oil prices volatile and elevated, despite softer global demand and slowing economic growth concerns
