Oil prices climbed on Friday as investors doubted the prospects of a breakthrough in U.S.-Iran peace talks, with the two sides still at loggerheads on Tehran's uranium stockpile and controls on the Strait of Hormuz. The market, however, remained headed for a weekly loss.
A senior Iranian source told Reuters no deal has been reached with the U.S. but the gaps have narrowed, while U.S. Secretary of State Marco Rubio said there had been "some good signs" in talks but any toll system in the strait would be unacceptable.
