Selling pressure accelerated after reports revealed US and Iranian negotiators in New York are exploring a phased framework to reopen the Strait of Hormuz in exchange for lifting Washington's economic blockade. Logistical sentiment was supported by steady waterborne flows, with weekly Hormuz crude shipments reaching 33.7 million barrels.

WTI lagged Brent as speculation regarding a potential 90-day US diesel export ban sparked fears that stranded domestic fuels would force US refiners to trim crude throughput, dragging US gasoline futures down 4%.

However, losses were cushioned by ongoing Houthi strikes on Saudi Arabia and a drone attack that temporarily idled Russia’s Novoshakhtinsk refinery, maintaining an elevated floor under refined product cracks and sustaining continuous feedstock cost-push pressure on petrochemical crackers.
