US diesel prices hit record $5.85/gallon, war-driven surge pressures inflation

US average diesel price reached an all-time high of $5.85 per gallon, surpassing the 2022 record, driven by rising costs since the Iran war began. The surge threatens to increase shipping costs and add inflationary pressure on consumer goods, compounding political challenges for President Trump. The trend is ongoing, with prices rising steadily for weeks and a 17-cent spike reported.
