Overview
- The national average for diesel hit about $6.05 per gallon on Friday, setting a fresh record and marking a rapid rise from roughly $5.32 a month earlier and $3.70 a year ago.
- The price surge reflects renewed fighting in the Middle East that has disrupted flows through the Strait of Hormuz, Russian diesel export limits and strikes on refining infrastructure that together have tightened product supplies.
- Major U.S. and global refiners report near-100% runs, which limits how quickly crude can be turned into diesel and prevents a quick market correction even as governments release oil from reserves.
- California is experiencing sharper pain: state averages have climbed above $8.00 per gallon and GasBuddy reported some pumps showing the $9.999 digital display limit, intensifying local cost pressures for households and businesses.
- Higher diesel is already being passed to customers through fuel surcharges and higher shipping fees, the August CPI and PPI readings show renewed inflationary pressure, and policymakers say meaningful relief depends on both easing geopolitical risks and time-consuming refinery adjustments.
