US gasoline futures rose above $3.15 a gallon, extending gains for a second session amid tightening fuel supply. Elevated tensions between the US and Iran remain an upward pressure, threatening further constraints to production and supply. Adding to the pressure, persistent attacks from Ukraine in Russian refineries pushed runs to multi-year lows. Meanwhile, EIA data showed US gasoline inventories fell 1.173 million barrels in the week ending August 28th, reflecting continued drawdowns in recent weeks while US refiners are largely out of capacity to boost further production, with facilities in Midwest operating at over 103% capacity and some delaying maintenance to keep production elevated. On September 4th, the US national average regular gasoline edged higher to $4.15 a gallon, its highest price ever for September, according to AAA. Earlier in the week, President Trump met with fuel refiners in an effort to bring down gasoline prices, although no measures were announced.
