US diesel prices climbed above $5 per gallon on Monday, reaching a level not seen since late 2022 as intensifying conflict involving Iran disrupts international fuel supplies. The price surge coincided with notable gains in both Brent and New York oil futures, reflecting widespread market concerns over energy availability.
The ongoing hostilities between the US-Israel alliance and Iran, now entering their third week, have created major obstacles for diesel producers worldwide. The Middle East’s pivotal role in supplying both refined diesel and optimal crude for its production has intensified these disruptions. According to the American Automobile Association, average US gasoline prices have also surpassed $5 per gallon, underscoring the broad impact on American fuel markets.
Brent crude advanced 3.93% to $104.15 per barrel, while the West Texas Intermediate surged 4.25% to $97.47. The crude market rally comes alongside a nearly complete blockade of the Strait of Hormuz by Iran, affecting roughly a fifth of global seaborne oil shipments. As a result, Asian refiners, heavily dependent on Middle Eastern crude, have scaled back operations, tightening diesel supply even further.
Economists have cautioned that persistent increases in diesel prices could dampen global manufacturing and logistics activity, as these sectors rely heavily on the fuel. Should higher production and shipping costs persist, consumers are likely to face additional price pressures. Rising fuel inflation is also seen as a significant political challenge for President Donald Trump and the Republican Party ahead of November’s midterm elections.
