IEA Flags Record 163-Mbbl Stock Draw as U.S.–Iran MoU Reopens Hormuz, Points to 2027 Oil Glut

On 18 June 2026 the IEA disclosed that OECD oil inventories have fallen 163 million barrels since the February war, hitting a 36-year low, even as a newly-signed U.S.–Iran memorandum orders the immediate reopening of the Strait of Hormuz and drives the agency to predict an 8 mb/d supply rebound and sizable surplus by 2027.

IEA data: OECD government stocks were drawn down at an average 3.8 mb/d, reaching their lowest point since December 1990 after a cumulative 163 mbbl decline.
To curb price spikes, 252 mbbl out of a planned 400 mbbl emergency release had been injected into the market by 12 June, the fastest draw on strategic reserves in the agency’s history.
The 17 June interim peace MoU, co-signed by the U.S., Iran and mediated by Pakistan, saw seven vessels transit Hormuz within 24 hours, while roughly 160 mbbl of crude remains bottled up in the Gulf awaiting clearance.

Stockpiles sliding to 1990 levels rhymes uneasily with the 1973–74 embargo, when OECD stocks also cratered and catalysed the creation of the IEA itself (1974). Today’s crisis again spotlights how a single chokepoint—this time Hormuz, not Suez 1956—can reorder flows, prices and diplomacy. The IEA’s forecast of a 2027 glut fits a longer oscillation: wartime scarcity prompts emergency releases and demand destruction; peace restores supply faster than demand, triggering the next bust, a cycle seen after the 1991 Gulf War and the 2014 shale surge. Over a 100-year horizon the episode underlines two structural forces: (1) physical chokepoints will keep giving mid-tier powers bargaining chips despite talk of energy transition, and (2) strategic reserves remain the West’s primary buffer, now visibly thinner just as climate-policy investments stall. Whether the world leverages the forthcoming surplus to rebuild buffers or slips back into complacency will determine resilience the next time a strait—or pipeline—shuts.
