Gasoline and diesel futures surged after US and Israeli attacks on Iran halted most tanker traffic through the Strait of Hormuz. Crude jumped about 14% and diesel futures rose as much as 17% on March 2, 2026.
Disruption to Hormuz tanker flows removes a major share of seaborne crude and fuel supply, pushing energy costs higher for farm diesel, transport and processing. Higher energy prices also lift the cost of fertilizer and biofuel-linked feedstocks.
