It’s not just gasoline prices spiking at the pump. The cost of diesel has jumped even more sharply since the outbreak of a major Middle East conflict sent oil prices surging.
The national average for gasoline recently hit its highest level this year, rising significantly over the past week. Diesel prices, however, saw an even larger increase over the same period, reaching their highest point in several years.
Analysts explain that diesel markets are highly global and particularly sensitive to shipping risks and maritime disruptions. The conflict has brought traffic to a standstill in a critical Middle Eastern shipping corridor, through which roughly a fifth of the world’s oil flows. “With elevated tension in a key global shipping corridor, diesel is reacting more aggressively than gasoline,” said one head of petroleum analysis.
This spike in diesel costs could soon be passed through to prices on other goods as companies face higher transportation expenses. “Higher diesel prices absolutely tend to filter into consumer prices, though usually with a lag,” the analyst noted. Diesel is the primary fuel for moving goods across the economy, especially long-haul trucking, which carries everything from groceries to construction materials.
Typically, this pass-through isn’t immediate because most trucking companies build fuel surcharges into existing contracts. The impact tends to show up when those contracts renew. “When diesel rises as quickly as it has recently… it can begin putting noticeable upward pressure on freight costs, shipping rates, and ultimately consumer prices if it persists,” the analyst added.
Oil prices themselves surged to their highest level in recent memory as the conflict continued to expand. Both major international and U.S. benchmark crude oil prices saw significant gains.
