The Oxford Institute for Energy Studies (OIES) published Quarterly Gas Review Issue 32 in April 2026, assessing the Q1 2026 global LNG supply cut at approximately 20% on the Iran war and Hormuz closure, and quantifying the EU additional injection requirement at 6 bcm more than Summer 2025 1.
OIES is the Oxford-based independent research body specialising in global energy markets; its Quarterly Gas Review is the reference document for trading desks sizing global LNG balances. A 20% Q1 supply cut is an exceptional loss by any historical comparison, and the institute's assessment is the closest thing the market has to an agreed figure for what the Hormuz closure did to first-quarter global supply.
The figure pairs with a corroborating primary estimate from the IEA April Oil Market Report. Two independent quantifications of the same order of magnitude give forward analysis a stable base to work from, and the OIES view narrows the uncertainty band on any mid-year resumption scenario. The closure of the pre-conflict Qatari supply bridge underlines how much of the 20% is now structural rather than transitional.
The 6 bcm shortfall versus last summer is the tighter ask inside a tighter global market. EU injection has matched rather than exceeded prior-year pace; the step-up required through May and June has not begun. Closing the gap depends on peripheral estates compensating for the German shortfall, constrained by the regasification envelope ENTSOG itself treats as fixed for the season. If Germany does not flip from net withdrawal before the 25 April ban , the OIES target moves out of reach inside the existing infrastructure. March's one-off surge in European LNG inflows was front-loading before the ban; the Q2 calendar does not contain another such window.
