WASHINGTON — U.S. Treasury Secretary Scott Bessent threatened Thursday to subject Iran to economic isolation "like the world has never seen before," adding that new measures are expected next week.

"It will be a combination of economic isolation, like the world has never seen before," Bessent told conservative television network Newsmax, adding that "the continued blockade in the Strait of Hormuz ... will keep anything from going in or out of the Iranian ports."

"Watch this space for more announcements coming next week," he said.

Bessent described a two-pronged approach featuring financial pressure and a physical blockade of the ports.
