US gasoline futures fell to around $3.26 per gallon on Thursday, giving back part of the previous session's gains as traders assessed conflicting geopolitical signals. Iran and Oman agreed on the allocation of their respective shares of the Strait of Hormuz's waters and related revenues, but Tehran said the agreement alone would not be enough to reopen the strategic waterway. Crude also appeared to be leaving the Persian Gulf. Russia was reportedly preparing to intensify attacks on Ukraine after judging peace negotiations to have reached a dead end, limiting the market's decline. The developments raised concerns that Russian refined-product export restrictions could persist as Ukrainian strikes pushed refinery runs toward multiyear lows. EIA (U.S. Energy Information Administration) data showed US gasoline inventories fell by 2.536 million barrels in the week ending August 21, a larger-than-expected decline that left stocks 6% below the five-year average.
