IEA Projects Historic Decline in Global Oil Demand Amid Strait of Hormuz Crisis

This significant decline in oil demand signals a turbulent period for global energy markets, affecting prices and availability.

• IEA forecasts a 1.5 mb/d decline in global oil demand for Q2 2026, the sharpest drop since COVID-19.
• Strait of Hormuz crisis leads to a historic 10.1 mb/d global supply plunge in March 2026.
• Annual demand for 2026 is now projected to contract by 80 kb/d, reversing previous growth expectations.

• The Strait of Hormuz crisis escalated in March 2026, with Iranian forces declaring the strait closed, disrupting 20 mb/d of oil flows.
• OPEC+ crude output fell by nearly 8 mb/d in March, marking the largest drop on record, with significant cuts from major producers like Saudi Arabia and Iraq.
• Surging oil prices reached $150/bbl for physical crude, prompting the IEA to revise demand forecasts downward amid ongoing geopolitical tensions.

The current oil market turmoil is rooted in the escalating conflict in the Middle East, particularly the Iran war, which has severely impacted the Strait of Hormuz—a critical chokepoint for global oil transportation. As of March 2026, Iranian forces declared the strait closed, leading to a cascade of supply disruptions that saw global oil flows plummet from 20 mb/d to just 3.8 mb/d. This drastic reduction in supply triggered a historic 10.1 mb/d drop in global oil output, with OPEC+ members, including the UAE, Saudi Arabia, and Iraq, implementing unprecedented production cuts.

The International Energy Agency (IEA) responded to these developments by projecting a 1.5 mb/d decline in global oil demand for Q2 2026, marking the sharpest quarterly drop since the COVID-19 pandemic. This forecast reflects a broader trend of declining demand, with the IEA also revising its annual demand expectations for 2026 downward by 80 kb/d. The combination of soaring prices—reaching $150/bbl for physical crude—and ongoing geopolitical instability has created a precarious environment for energy markets.

The implications of this crisis extend beyond immediate supply and demand dynamics. As oil prices surge, consumers and businesses face increased costs, which can lead to inflationary pressures across various sectors. Additionally, the ongoing conflict raises concerns about the stability of energy supplies, prompting governments and organizations to explore demand-reduction measures and stock releases to mitigate potential shocks. The situation remains fluid, with a temporary two-week ceasefire providing only limited relief amid persistent risks.

In the UAE, a key player in the OPEC+ alliance, the impact is particularly pronounced. Residents are experiencing elevated fuel prices, with jet fuel shortages affecting aviation operations in Dubai. The ripple effects of these developments are likely to be felt across the global economy, as energy prices influence everything from transportation costs to consumer goods.

• Airlines and travel sectors: Facing jet fuel shortages and increased operational costs, leading to potential flight disruptions.
• Consumers: Experiencing higher fuel prices at the pump, impacting daily commuting and travel expenses.
• Businesses reliant on oil: Facing increased costs for transportation and logistics, which may affect pricing strategies and profit margins.
• Governments: Implementing consumer price shields and exploring demand-reduction measures to stabilize markets.

• OPEC+ output decisions: Watch for potential output hikes or further cuts as the group navigates the crisis, which will directly impact global oil prices.
• Geopolitical developments: Monitor the situation in the Middle East, particularly any escalations or resolutions that could affect oil supply routes.
• Consumer price trends: Keep an eye on fuel prices and inflation rates, as sustained high oil prices could lead to broader economic implications.
