Europe Sidestepped the Jet Fuel Crisis, but a 500,000-Barrel Import Deficit Remains
The feared European aviation fuel shortage proved overblown, yet the continent's structural 500,000-barrel-per-day import deficit remains exposed to any renewed Hormuz disruption.
Ryanair's warning, issued during the peak of Strait of Hormuz tensions, that a reduction of between 10% and 20% in available jet fuel supply could force European airlines to cut summer capacity has not been realised. Analysis published on Sunday (2026-07-19) concluded that the shortages forecast for June failed to materialise, with aviation fuel markets across Europe stabilising more quickly than much of the industry had expected.7
The disruption that prompted those warnings was real. At peak severity, roughly 14 million barrels per day of oil supply were cut off, equivalent to about 14% of global daily demand. The strait had previously handled nearly 20 million barrels per day of crude oil and petroleum products — approximately one-quarter of worldwide seaborne oil trade and about one-fifth of global LNG flows. Gulf producers had also supplied a significant share of the world's diesel and jet fuel before the conflict began.7,5
European aviation entered the episode with a pre-existing structural gap. The continent consumes roughly 1.6 million barrels per day of jet fuel and kerosene but produces closer to 1.1 million barrels per day, leaving approximately 500,000 barrels per day to be sourced from imports. A significant share of that import requirement had historically flowed from Middle Eastern refineries.7
Two adjustments kept shortages from developing. European refineries raised throughput while importers redirected cargoes from non-Middle East sources, according to Rigzone reporting from late June (2026-06-28). The sector gave reassurances through the period: "Our fuel suppliers don't expect problems this summer," said Thomas Thessen, as quoted by Rigzone.6
Stock buffers across Europe were uneven heading into the disruption. The continent as a whole held 38 days of commercial jet fuel inventory, with government strategic reserves lifting that aggregate to 57 days, according to Goldman Sachs estimates cited in a mid-May (2026-05-19) Economist analysis. Britain was the most exposed: it holds no strategic jet fuel reserve and carried only 29 days of commercial stock, well below the continental average.3
The gas market has run on a parallel but slower track. European gas stores entered the injection season at approximately 28% capacity following a prolonged winter, against the 50% seasonal norm that typically supports the EU's 80-90% winter fill target. By late May (2026-05-24), storage had recovered to 35-37%, still well short of seasonal norms, according to Equinor executives cited by oilprice.com. Analysts told Montel in late May (2026-05-21) that storage could reach an "adequate" 86% by winter if the strait reopened promptly, but that a closure persisting beyond July would likely trigger gas price spikes. ICE Endex TTF front-month was quoted at €57.51 per megawatt-hour as of Sunday evening (2026-07-19). The same analysts warned that hot, dry summer conditions could push European power prices 10% higher from prevailing levels, compounding the storage pressure.4,12
The aviation industry's resilience through this period reflects market incentive rather than structural change. Airlines avoided capacity cuts, but rerouting jet fuel supply chains to non-Middle East origins lengthened transit times and increased freight exposure. Incoming cargoes on longer routes carry higher weather disruption risk and greater sensitivity to shipping market conditions. The speed of the rerouting says more about what elevated prices can unlock than about any durable increase in European refinery capacity or supply security.6,7
ICE Brent crude front-month traded at $90.78 per barrel as of early Monday (2026-07-20). European gas storage at 35-37% as of late May (2026-05-24) implies a sustained injection rate to hit EU winter targets, and any return of meaningful disruption on the Hormuz corridor — which previously moved roughly one-fifth of global LNG trade — would erode that trajectory directly. Airlines that drew on fuel hedges through the crisis will be reporting that cost when second-quarter results land. The 500,000-barrel-per-day structural import requirement for European aviation fuel has not diminished. New supply lines have filled it, for now, at a higher cost.4,57
