According to CoinMeta, and based on data from the price tracking agency GasBuddy, the national average price of diesel in the United States exceeded $6 per gallon for the first time on Thursday local time. The US-Iran war and Ukraine's attacks on Russian refineries have led to a squeeze on diesel supply. Diesel is a crucial pillar of economic activity, providing fuel for trucks, trains, ships, and heavy equipment that are essential for maintaining the supply chain, as well as being an important energy source for agricultural production. Rising fuel prices have become a thorny issue for US President Donald Trump and Republican lawmakers, who are striving to maintain the Republicans' narrow majority in the US Congress during the mid-term elections in November. Patrick DeHane, an analyst at GasBuddy, said, "Every trip for a truck, every delivery, every package, and every purchase of groceries has now become more expensive." He also noted, "Record-high diesel prices could potentially reignite inflation throughout the entire supply chain." According to the agency's data, the average price of diesel in the US has risen by about $2.30 compared to a year ago.
