“The International Energy Agency estimated in May that Gulf oil supply through the Strait of Hormuz was down by 14.4 million barrels a day, approximately 14% of the world’s supply.”
Attributed to Washington Examiner (opinion piece)
The article cites an IEA estimate to support the argument that Iran’s actions harmed Gulf oil exports during the conflict, saying Iran “weaponized geography” and that the IEA put the May shortfall at 14.4 million barrels per day (~14% of world supply).
What the proof shows
The IEA’s May 13, 2026 Oil Market Report does state that output from Gulf countries affected by the Strait of Hormuz closure was about 14.4 million barrels per day below pre‑war levels (supports the 14.4 mb/d figure). However, the IEA distinguishes ‘Gulf output’ from actual tanker flows through the Strait: a separate IEA commentary says flows through the Strait fell from about 20 mb/d pre‑war to an average ~2.7 mb/d in March–May (a larger transit reduction). Whether 14.4 mb/d is “~14% of the world’s supply” depends on the baseline: using IEA’s 2026 supply/demand figures (≈102.2–104 mb/d) 14.4 mb/d is indeed roughly 14%, but the Washington Examiner wording conflates Gulf output and Strait transit flows and omits the baseline used for the percentage. In short: the numeric shortfall (14.4 mb/d) is from the IEA, the percent is plausible with IEA baselines, but the article’s phrasing about ‘‘through the strait’’ lacks the nuance the IEA provides.
Corrected version
IEA’s May 13, 2026 Oil Market Report says output from Gulf countries affected by the Strait of Hormuz closure was about 14.4 million barrels per day below pre‑war levels; using IEA global supply baselines (~102–104 mb/d) that shortfall is roughly 14% of global supply. The IEA also notes flows actually moving through the Strait fell from ~20 mb/d pre‑war to ~2.7 mb/d in March–May, a different (and larger) measure of transit disruption.
