US retail diesel prices rise to their highest level in about four years, with the national average pump price reaching $5.783 a gallon on Wednesday, according to the American Automobile Association. That level is above the prior peak seen in the early period of the US-Iran war and is approaching record highs, Quartz also reports that diesel averages about $5.78 per gallon.

The higher prices are linked to strains on global fuel supplies as multiple conflicts affect oil markets. Bloomberg frames the move as part of broader inflationary pressure tied to the conflict’s drag on global supply, while Quartz emphasizes the increase in relation to the start of the Iran war and the pace of gains. Despite differences in framing, the outlets broadly agree diesel prices are near records and are moving upward alongside oil price strength.
