The blockade of the Strait of Hormuz is causing concern in Europe, which relies heavily on imported jet fuel.

The European Union is mulling jet fuel imports from the United States and new minimum reserve quotas as it eyes options amid a supply crunch due to the Iran conflict.

Despite mounting pressure on jet fuel supplies in the EU, there is no evidence of “actual shortages” of jet fuel currently, and widespread flight cancellations are not expected over the summer, Transport Commissioner Apostolos Tzitzikostas insisted on Tuesday.

The EU official’s bid to calm worries came amid the continued blockade of the Strait of Hormuz, which is normally the passage for one-fifth of the world’s oil and liquefied natural gas supplies, has raised concerns about supply across the globe.

Last week, the head of the International Energy Agency, Fatih Birol, said that Europe has “maybe six weeks or so [of] jet fuel left”, warning of possible flight cancellations “soon” if oil supplies remain halted by the war.

Tzitzikostas admitted that stocks were “under pressure” in parts of Europe, but said that the EU is following the situation closely, the market is responding to the pressure, and there were no signs of bottlenecks.

He acknowledged that some carriers had cancelled flights, but asserted that it was on account of high fuel costs, not for lack of supply.

Airlines will be provided with guidance on passenger rights and public service obligations in the event of jet fuel shortages, he said.

The EU imports 30 to 40 percent of its jet fuel needs, with roughly half coming from the Middle East.

“Europe maintains emergency stocks. These stocks can be and will be released only if necessary. At this stage, however, the market is managing the pressure, and there is no evidence of actual shortages,” Tzitzikostas said.

Suspended flights

The European Commission is due to present a broad package of energy and transport measures on Wednesday. Tzitzikostas said a new “fuel observatory” to monitor supplies will be established, starting with jet fuel.

The EU is also investigating alternative supplies of jet fuel, including from the US.

The prospect of jet fuel shortages has rattled the aviation industry as the Northern Hemisphere summer travel season approaches. Some airlines have already suspended flights or imposed fuel surcharges.

“We must also be ready for any future shocks, so we will assess whether we need a minimum stock obligation for jet fuel, requiring member states to maintain a minimum emergency reserve,” Tzitzikostas said.
