Iran introduced new maritime rules requiring foreign vessels to use designated routes in the Strait of Hormuz, while also saying it has the exclusive right to manage traffic in the waterway under a preliminary peace deal signed with the U.S. Foreign Minister Abbas Araghchi made the comments on Sunday after several days of back-and-forth strikes with the U.S. The developments renewed concerns about potential oil supply disruptions through the key shipping chokepoint. In late trading at 2349 GMT, front-month WTI crude futures rose 0.8% to $69.78 a barrel and front-month Brent crude futures gained 0.4% to $72.27, as ANZ Research said the market was likely to reconsider assumptions of a quick recovery in Persian Gulf oil supply.
