Brent crude slipped toward $88 per barrel on Friday, trimming gains from the previous session as traders monitored Middle East developments and efforts to reopen the Strait of Hormuz. Goldman Sachs said Persian Gulf oil exports had recovered to around two-thirds of pre-war levels as flows through Hormuz increased. Regional crude exports reportedly reached 15 million to 16 million barrels per day, remaining 7 million to 8 million barrels below pre-conflict levels but well above the 5 million to 6 million barrel trough recorded in March. Iran and Oman reached a revenue-sharing agreement over the waterway, though Tehran said the deal did not guarantee an immediate reopening. The Trump administration also told mediators it was not interested in restoring the terms of a preliminary agreement with Iran reached in June and later abandoned.
