European Jet Fuel Stocks Held at 30 Days of Cover as Hormuz Shortage Forecasts Failed to Hit
European jet fuel inventories held near 30 days of demand in early June, defying shortage forecasts despite the Strait of Hormuz disrupting roughly 14% of global oil supply.
European jet fuel and kerosene stocks stood at roughly 38 million barrels at the start of June, equivalent to approximately 30 days of the continent's consumption, according to a market analysis published July 19 (2026-07-19). Forecasts made in the spring had pointed toward physical shortages by summer. Those shortages did not arrive.7
The gap between expectation and outcome was substantial. Ryanair had stated the risk explicitly: a loss of 10% to 20% of available jet fuel supply, the carrier suggested, could force European airlines to cut capacity during the peak summer travel season. Europe's structural position made those warnings plausible — 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 a chronic import deficit of approximately 500,000 barrels per day that had been met primarily by flows through the Strait of Hormuz.7
The Strait closed on February 28 (2026-02-28). At its most severe, the disruption cut roughly 14 million barrels per day of supply, about 14% of global oil demand, from a route that had previously carried nearly 20 million barrels per day of crude and petroleum products before the conflict began.7
Two forces absorbed much of the shock. On March 11 (2026-03-11), the 32 members of the International Energy Agency agreed to release 400 million barrels from strategic reserves, the largest co-ordinated drawdown in the IEA's history, equivalent to around a third of its total emergency holdings. US jet fuel production simultaneously climbed to record highs in the weeks following the closure, as domestic refiners scaled up output after jet fuel prices roughly doubled in March.2,4
Still, the pace of inventory draw through the spring was severe. Observable global oil stocks fell by a cumulative 246 million barrels across just two months: a 129 million-barrel draw in March followed by a 117 million-barrel decline in April, equivalent to a combined rate of approximately 3.9 million barrels per day, according to data published by the Oil & Gas Journal on June 8 (2026-06-08). Kayrros, tracking crude inventories using satellite data, put the overall crude stock decline at 13%, down to 545 million barrels.3,2
The relief was not uniform across Europe. Britain imports around 65% of its jet fuel requirement and faced acute exposure throughout the disruption period. Greece and the Netherlands, both net exporters of refined products, were less vulnerable. Distillate markets more broadly reflected the severity of the squeeze: The Economist on May 17 (2026-05-17) reported diesel cargoes changing hands at $600 per barrel, up from $300 a week earlier.1,2
Asian markets provided a parallel pressure point. A bank, as reported by The Economist in May 2026 (2026-05-19), forecast that Asian refineries dependent on Gulf crude could face a jet fuel shortfall of up to 800,000 barrels per day in May alone, adding up to roughly 15% of total global jet fuel demand. South Korean refiners, which supply approximately 85% of West Coast US jet fuel imports, were themselves constrained by the loss of Gulf crude feedstock, tightening an already strained Atlantic product market.1
The EIA, in its June 2026 Short-Term Energy Outlook published June 10 (2026-06-10), assumed the Strait would remain effectively closed in the near term and modelled a resumption of oil shipments in the third quarter of 2026. With August now under way, that modelled window is current. ICE Brent crude front-month stood at $82.38 per barrel as of August 9 (2026-08-09). Commerzbank analyst Norman Liebke said the situation marks a turning point for energy markets, though the pace of normalization remains uncertain.5,6
Europe held its 38 million-barrel buffer through the spring. But the strategic reserve release was a one-time drawdown, US production has physical limits, and autumn demand from both aviation and heating will compete for the same middle distillate pool. Whether the Hormuz corridor reopens on the EIA's third-quarter timeline, and how quickly that translates into meaningful product flows to European markets, will shape the jet fuel price outlook through the close of 2026.7,5
