Oil prices fell as markets awaited details of a US plan targeting Iran, while investors turned their focus to Nvidia and the AI boom.

Oil prices fell on Monday as investors braced for details of a US plan to isolate the Iranian economy that President Donald Trump billed as the "most crushing" financial operation ever against Tehran.

The United States warned allies and China on Thursday to join Trump's new campaign, which comes as the unpopular war in the Middle East drags toward the six-month mark.

US Vice President JD Vance admitted the plan was a "delicate dance" because Iran will "try to apply economic pressure to us".

Asked whether the United States would pressure China, Bessent told CNBC that "many conversations are best to have in private", but called on Beijing "to get with the programme".
