European airline equities tumbled on Monday, with declines ranging from 2.7% to 7.7% as global oil benchmarks spiked. Brent crude rose 8% to $102.78 a barrel as of 05:00 ET (09:00 GMT), recording an intraday peak at $103.49 a barrel. U.S. crude West Texas Intermediate increased 7.2% to $96.03.
The jump in oil prices put pressure on several major European carriers, including Ryanair, IAG, Lufthansa, Air France-KLM, easyJet and Wizz Air, all of which saw their shares suffer during the session.
Officials in Washington moved to tighten maritime access to Iran following the breakdown of ceasefire talks in Pakistan. U.S. President Donald Trump ordered the Navy to impose a blockade on Iranian ports. U.S. Central Command said the restriction on vessels entering and leaving Iranian ports would begin at 10:00 ET Monday. The Central Command described the blockade as narrower in scope than an earlier U.S. threat to stop all shipping transiting the Strait of Hormuz.
The delegation led by U.S. Vice President JD Vance left Pakistan early Sunday after 21 hours of talks that did not produce an agreement. Participants left a number of issues unresolved, including Iran's nuclear activities, the potential reopening of the Strait of Hormuz and Tehran's backing of proxy groups such as Lebanon's Hezbollah.
Iran stated it had no plans to resume nuclear negotiations with the United States, and President Trump said he did not care whether Iran returned to talks. Separately, the Wall Street Journal reported that Middle Eastern governments were working to arrange further discussions between Washington and Tehran.
Market attention is also focused on the operational impact of the Strait of Hormuz disruption. Iran has maintained a blockade of the strait since late February, a move that cut off roughly 20% of the world's oil supply and has contributed to sustained turbulence in oil markets.
The immediate market reaction pushed fuel-sensitive sectors into focus, with listed European airlines bearing the brunt of the sell-off as investors priced in higher fuel costs and continued supply uncertainty.
