US diesel hits record $5.85/gal as Iran blocks Strait of Hormuz

US diesel prices reached a record $5.85 per gallon on Friday, surpassing the 2022 peak, as energy markets react to the US-Iran conflict and Tehran's blockade of the Strait of Hormuz. The blockade threatens a major hydrocarbon transit chokepoint, amplifying supply concerns. The record is driven by geopolitical risk premium and potential supply disruption, with the full impact on global energy flows still uncertain.
