Diesel Prices Surge to Highest Levels Since 2022 as Middle East Conflict Escalates

U.S. Diesel prices have climbed to $5.04 per gallon, marking the highest level in over three years, driven by escalating tensions and disruptions in the Middle East. The surge is impacting the transportation sector and raising concerns about broader economic consequences.

The Impact of the Middle East Conflict

The recent escalation of conflict in the Middle East, following U.S. And Israeli airstrikes against Iran, has triggered a significant disruption to global oil supplies. This disruption is the largest in history, according to industry analysts. Since the start of the conflict, diesel prices have increased by 34%, whereas gasoline prices have risen by 27% to an average of $3.79 per gallon [CNBC]. Gasoline prices have reached their highest level since October 2023.

Diesel’s Critical Role in the U.S. Economy

Diesel fuel is a vital component of the U.S. Economy, powering the transportation of goods via trucks, trains, and barges. The increased cost of diesel is already prompting trucking and rail companies to implement fuel surcharges [CNBC]. Experts, such as Andy Lipow, president of Lipow Oil Associates, warn that higher diesel prices should be a significant concern [CNBC].

Global Refinery Issues Contribute to Price Increases

The rise in diesel prices isn’t solely attributable to the Middle East conflict. Global refinery margins for diesel have been widening since late October 2025, reaching their highest levels of the year. This is due to refinery outages in Russia and the Middle East, coupled with new sanctions imposed on Russian crude oil [U.S. Energy Information Administration]. These factors have led to limited refinery production and a decrease in the global diesel supply.

Crack Spreads and EU Sanctions

Crack spreads, which indicate the profitability of refining crude oil into diesel, have increased sharply. Spreads in key locations like New York Harbor, the U.S. Gulf Coast, and the ARA shipping hub (Amsterdam, Rotterdam, Antwerp) all rose above $1 per gallon in mid-November 2025 [U.S. Energy Information Administration]. New EU sanctions against Russian oil companies, including Rosneft, Lukoil, and Gazprom Neft, have further tightened the global diesel supply [U.S. Energy Information Administration].

Potential for Further Price Increases

Analysts predict that gasoline prices could reach $4 per gallon [CNBC]. Oil prices have already jumped more than 40% during the conflict, with U.S. Crude oil trading around $94 per barrel and Brent prices around $101 per barrel [CNBC]. Disruptions in Middle East oil flows and refinery outages are restricting the global supply of middle distillates, which include diesel [MSN].

Middle East Reliance on Diesel

The impact of rising diesel prices extends beyond the U.S., particularly in Middle Eastern countries where functioning public power grids are lacking. Diesel is crucial for powering backup generators that provide essential services like water pumping and air conditioning [DW]. As diesel prices soar, access to electricity becomes increasingly expensive for residents in these regions [DW].
