Oil Posts Weekly Gain as IEA Warns Markets Could Remain Severely Undersupplied Through October
BLUFInventory buffers are gone, and even a near-term ceasefire leaves markets structurally short into late 2026, meaning prices will stay elevated and volatile regardless of when the Strait reopens.
Brent crude settled Friday at $109.26 a barrel, up nearly 8 percent on the week, and WTI at $105.42, up 10.5 percent, as the Strait of Hormuz remained effectively closed. The IEA's May Oil Market Report, published May 13, assessed global markets as "severely undersupplied" and projected the deficit will persist through Q3 2026 even if the conflict ends by early June. The agency cited a cumulative supply loss already exceeding 1 billion barrels and a projected 3.9 million b/d fall in full-year global production, as global inventories fell 250 million barrels over March and April. The EIA separately reported a 4.3-million-barrel draw in US commercial crude stocks for the week ending May 8.
Analysis
The IEA May report, a single-source assessment, marks a structural revision from projected glut to a 1.8 million b/d annual shortfall, with the acute phase running roughly 6 million b/d before non-Gulf compensating flows that do not close the gap. The March–April inventory draw has erased the commercial buffer, with restoration requiring roughly 1 million b/d of excess supply for three years post-conflict. Confidence in any price trajectory remains low, with IEA and OPEC demand estimates diverging by more than 1.6 million b/d and conflict duration flagged as a variable that could double the cumulative deficit. OPEC's demand-growth projection suggests destruction may prove self-limiting, enabling faster rebalancing than the deficit-through-Q3 baseline assumes.
