WASHINGTON, D.C. — Diesel prices in Europe and the United States have risen sharply as two separate wars curtail supply, but data from the International Energy Agency shows the Middle‑East conflict has cut diesel exports by a larger margin than the Russia‑Ukraine war.

Since the start of the Russia‑Ukraine conflict, Russian diesel shipments to the European market fell by roughly 22 percent, equivalent to about 1.1 million metric tons per month, according to the IEA. In the same period, diesel output from the Middle East, primarily Saudi Arabia and Iraq, dropped 31 percent, or about 1.5 million metric tons, after key ports were disrupted by hostilities.

“The reduction in Middle‑Eastern diesel exports has a more immediate impact on global spot prices because the region supplies a larger share of the refining feedstock used in Europe,” said Maria Lopez, senior analyst at Energy Insights. “When those flows tighten, refiners scramble for alternative sources, driving up freight costs and ultimately retail diesel prices.”

U.S. defense spending has risen 7 percent year‑over‑year, reflecting concerns over supply‑chain vulnerabilities. The Department of Defense has earmarked $1.2 billion for strategic fuel reserves and for research into synthetic diesel alternatives, a move aimed at insulating the military from price spikes tied to foreign conflicts.

Logistics firms report longer transit times for diesel shipments crossing the Red Sea, with average delays of 3‑5 days since the escalation of fighting in Yemen. These delays add roughly $0.12 per liter to the end‑user price, compounding the effect of reduced export volumes.

Key Takeaways

• Middle‑East diesel exports have fallen 31 percent, outpacing the 22 percent decline from Russia.
• Increased U.S. defense spending includes $1.2 billion for fuel security and alternative diesel research.
• Supply‑chain disruptions add $0.12 per liter to diesel costs in Europe and North America.

Analysts conclude that while both wars strain global diesel markets, the larger export loss from the Middle East translates into higher price volatility and underscores the strategic importance of diversifying fuel sources and bolstering national reserves.
