US Diesel Averages $5.85 a Gallon as Supply Concerns Mount

Diesel prices in the United States reached an average of 5.85 dollars per gallon on Friday, surpassing the previous peak set after Russia's invasion of Ukraine and marking the highest level recorded by the American Automobile Association. The increase follows six months of conflict involving the United States and Israel against Iran, which has restricted oil flows through the Strait of Hormuz and driven up wholesale crude costs since late February.

Diesel powers much of the nation's freight, farming, construction, and public transit systems. Higher fuel expenses have raised transportation costs for goods ranging from produce and meat to clothing and household items. Businesses have begun passing some of these charges along through surcharges on deliveries and online orders, with further effects likely to appear on store shelves if prices remain elevated. Regular gasoline prices have also risen, reaching an average of 4.15 dollars per gallon compared with 3.20 dollars a year earlier, though the increase has been less steep than for diesel.

Before the conflict began, the national diesel average stood near 3.76 dollars per gallon. The current surge reflects basic supply constraints in a market where sudden reductions in crude availability quickly translate into higher pump prices. Commercial users, who account for the bulk of diesel consumption, face the most immediate pressure, and those costs eventually reach consumers through everyday purchases.

In response, President Donald Trump announced an oil development agreement with Venezuela aimed at increasing global supply and lowering fuel costs for Americans. The deal covers 17 strategic fields with an estimated 65 billion barrels of proven reserves and includes more than 100 billion dollars in investment along with projected tax revenue exceeding 209 billion dollars for Venezuela. Under the terms, the United States would hold 55 percent control of a joint venture with a private operator. The agreement follows the earlier capture of former Venezuelan leader Nicolás Maduro by U.S. forces.

Analysts have expressed doubts about whether the arrangement can overcome longstanding barriers to investment in Venezuela's oil sector. Decades of nationalization, weak property rights enforcement, and institutional instability have repeatedly deterred capital and reduced output despite the country's large reserves. Past attempts to revive production through state-directed partnerships have often fallen short of targets because production depends less on announced investments than on consistent rules that protect returns and allow efficient operations.

Market prices continue to signal the underlying scarcity created by the conflict. Efforts to expand supply through new foreign arrangements face the same economic realities that have limited output elsewhere when governance and incentives are misaligned. The effects on transportation and consumer costs are expected to persist until either production rises substantially or demand adjusts through higher efficiency or reduced activity.
