Discussions included Houthi attacks on Saudi Arabia, the possibility of U.S.-Iran talks, disruptions to shipping through the Strait of Hormuz and Washington’s blockade of Iranian ports, reports showed.

The diplomatic efforts have helped ease some of the immediate concerns about further military escalation, but investors remain cautious about whether they will produce a lasting de-escalation.

U.S. President Donald Trump has continued to leave open the possibility of further military action against Iran, while Tehran has said negotiations with Washington would require concessions, including an end to the U.S. blockade and the lifting of sanctions on Iranian oil exports.

The risks to supply remain substantial. The Iran conflict has disrupted commercial shipping through the Strait of Hormuz and the Bab el-Mandeb Strait, two important routes for global energy trade.

Houthi forces said on Monday they had attacked pumping stations on Saudi Arabia’s East-West crude pipeline and Riyadh airport, although Saudi Arabia had not immediately confirmed the claims. The kingdom has reported intercepting missiles and drones in recent days.

The International Energy Agency’s executive director, Fatih Birol, said on Monday that energy markets were unlikely to return to their pre-war conditions in 2027, underscoring concerns about the lasting impact of the conflict on supply chains.
