Oil prices edged higher as prospects for reopening the Strait of Hormuz weakened. Front-month WTI crude oil futures rose 0.1% to $83.59 a barrel at 2335 GMT. The Trump administration told mediators it had no interest in returning to the terms of a preliminary deal reached with Iran that later fell apart. Hopes for reopening the waterway had increased after Iran and Oman reached an agreement on revenue sharing on Hormuz earlier this week, but ANZ Research analysts said those prospects had since faded.
