International Energy Agency warns of critically low oil stockpiles before summer demand peak

Global inventories have plunged by 250 million barrels in just two months as Gulf production losses mount past 1 billion barrels cumulative.

The International Energy Agency just dropped the kind of warning that makes energy traders lose sleep. Global oil stockpiles are draining so fast that they could hit historically low levels right as summer driving season cranks up demand to its annual peak.

In its May 2026 Oil Market Report, the IEA painted a picture of a market hemorrhaging supply with no quick fix in sight. The numbers are stark: observed global oil inventories fell by 250 million barrels during March and April, a drawdown rate of roughly 4 million barrels per day. April alone saw 170 million barrels vanish from onshore storage.

A supply crisis with no easy exit

The root cause is familiar but no less severe for it. Ongoing supply disruptions in the Middle East have gutted Gulf oil production, which now sits 14.4 million barrels per day below pre-war levels. To put that in context, the total cumulative supply loss has surpassed 1 billion barrels.

World oil supply dropped to 95.1 million barrels per day in April 2026, down 1.8 mb/d from the month prior. Further declines are expected for the remainder of the year.

The Strait of Hormuz is only expected to see a gradual resumption of oil traffic starting in June 2026. The IEA projects the market will remain in deficit until Q4 2026, meaning several more months of inventory erosion before any meaningful balance returns.

Toril Bosoni, head of the IEA’s Oil Industry and Markets Division, indicated that stock levels could reach critically low or even historical lows just before the peak summer demand period.

Emergency reserves already deployed

In March 2026, the agency authorized an unprecedented emergency stock release of 400 million barrels, the largest coordinated drawdown in its history. That release bought time rather than solved the underlying problem — the deficit persists, and inventories continue to drain.
