Brent crude slipped toward $88 per barrel on Friday, paring gains from the previous session as traders continued to monitor developments in the Middle East and efforts to reopen the Strait of Hormuz. Goldman Sachs said oil exports from the Persian Gulf have recovered to around two-thirds of pre-war levels amid increased flows through Hormuz. Total crude exports from the region have reportedly risen to 15-16 million barrels per day, still around 7-8 million barrels below pre-conflict levels but well above a trough of 5-6 million barrels in March. Iran and Oman also reached a revenue-sharing agreement over the strategic waterway, although Tehran stressed that the arrangement does not guarantee an immediate reopening of the strait. Meanwhile, the Trump administration told mediators that it has no interest in returning to the terms of a preliminary deal reached with Iran in June that later collapsed.
