Those shortages largely failed to materialise, revealing both the adaptability of global energy markets and their persistent tendency to price worst-case scenarios long before they occur.When the Strait of Hormuz was effectively closed at the end of February, the first forecasts were dramatic. The disruption affected a route that had carried nearly 20 million barrels per day of crude oil and petroleum products before the conflict, while Gulf exporters had also supplied a significant share of the world's diesel, jet fuel and liquefied petroleum gas. Europe appeared particularly exposed because it imported far more aviation fuel than it produced and had relied heavily on supplies originating in the Middle East.By April, warnings of physical shortages were becoming increasingly specific. The International Energy Agency estimated that Europe could begin running short of aviation fuel in June if it managed to replace only half of the supplies normally imported from the Gulf. Airlines warned that flights might have to be cancelled, airports considered contingency measures, and European officials began discussing the coordinated release and redistribution of jet fuel reserves. Ryanair suggested that a loss of 10% to 20% of available supply could force airlines to cut capacity during the summer season.June has now passed, however, and European aviation has not ground to a halt. Petrol stations have not broadly run dry, diesel rationing has not been introduced and the widespread physical shortages that dominated the early discussion have not occurred. Prices increased sharply, inventories declined and individual routes became less economical, but the energy system absorbed a disruption that the IEA described as the largest in the history of the global oil market.
