Iran War Drives Record Global Oil Inventory Drawdown
5/11/2026, 2:04:42 AM
War-Induced Oil Supply Shock
The conflict in Iran and the near-closure of the Strait of Hormuz have sharply cut Persian Gulf oil flows, forcing unprecedented draws on strategic and commercial stockpiles.
Pre-War Inventory Levels
Global oil inventories fell from over 90 days of demand in 2021 to below 80 days by 2022; the current crisis is pushing the buffer toward historic lows.
Scale of the Drawdown
- TotalEnergies says daily draws of 10-13 million barrels have erased about 500 million barrels since the war began.
- Rystad Energy estimates a total loss of 1.2-2 billion barrels (16-27 % of pre-war supply), with a 600 million-barrel draw since March.
- Morgan Stanley records a daily decline of 4.8 million barrels between 1 March and 25 April, the fastest quarterly drawdown on record.
Regional Shortages and Market Effects
Asia’s crude imports fell 30 % YoY, hitting a decade low, and naphtha and diesel supplies are tightening, especially in Pakistan, Indonesia and the Philippines. Europe’s jet-fuel stocks at the Amsterdam-Rotterdam-Antwerp hub have slumped a third, while U.S. gasoline inventories sit 4 % below the five-year average, the lowest since 2014.
Government and Industry Responses
- The IEA coordinated a pledge to release 400 million barrels from emergency reserves; the United States has drawn about 79.7 million of its 172 million-barrel pledge.
- JPMorgan’s Natasha Kaneva warned OECD inventories could reach “operational stress” by early June and “operational minimum” by September if the strait stays closed.
- TotalEnergies CEO Patrick Pouyanne noted the world is exiting the conflict with “clearly some very low inventories.”
- Chevron CFO Eimear Bonner said “a lot of the inventory and spare capacity has been depleted already.”
Analyst Concerns
Analysts argue that further strategic-reserve releases would erode the remaining buffer and prolong market instability, while some traders point to robust Chinese stockpiles that could soften the shock.
Discrepancies in Data
Key Voices
- “Inventory support remains finite and cannot sustainably offset prolonged disruptions.” — Kpler analyst
- “Even if the conflict, and I hope so, will end in the month of May, we would exit the conflict with clearly some very low inventories.” — Patrick Pouyanne, CEO, TotalEnergies
- “Inventories are acting as the shock absorber of the global oil system.” — Natasha Kaneva, Head of Global Commodities Research, JPMorgan Chase & Co.
- “Since February, we have seen a steady drop in jet fuel stocks.” — Lars van Wageningen, Research and Consultancy Manager, Insights Global
Future Outlook
If the Strait remains closed past early June, OECD nations may face operational stress, prompting additional emergency releases. Analysts expect a “restocking phenomenon” once flows resume, potentially pushing sovereign reserves above pre-war levels.
