The average U.S. diesel price has reached $6.51 per gallon, according to AAA, up from $5.60 a month earlier and $3.68 a year earlier, while Rep. Rick Crawford said Americans are fatigued by rising fuel costs during the nearly seven-month US-Iran war. Diesel prices have been driven higher by reduced tanker traffic through the Strait of Hormuz and the Red Sea, Ukrainian strikes on Russian refineries, Russia’s continuing diesel-export ban, and broader regional supply disruptions. California, Hawaii and Washington reported averages of $8.427, $7.18 and $7.40, respectively. President Donald Trump has supported restricting diesel exports and is considering diesel-tax relief and changes to dyed red diesel rules, but Energy Secretary Chris Wright said an outright ban "definitely doesn’t work," and the White House has denied preparing a specific 90-day ban. The UK, which relies heavily on U.S. diesel imports, warned that a restriction could threaten supply and price stability. Analysts say a 90-day ban could lower prices initially but might prompt refiners to cut production, potentially tightening global supplies and raising prices later.
