Diesel prices have surged to record levels across Europe and the United States, reflecting a perfect storm of geopolitical conflict and limited refinery capacity. Wars in Iran and Ukraine have sharply reduced exports from major producers such as Russia, Saudi Arabia and the United Arab Emirates, leaving little room for price relief.

Global Supply Disruptions Drive Prices Higher

European diesel futures closed at an all‑time high last week, more than doubling their level at the start of 2026. The spike follows supply disruptions that have spread to the Red Sea, where Saudi Arabia loads the majority of its diesel shipments. In the United States, refineries operated at their highest output in eight years in late August, according to the International Energy Agency (IEA), yet the market remains stretched.

“A key issue is that many refineries around the world are already stretched to capacity,” the IEA wrote in a Monday newsletter. “This leaves few available options to prevent a further tightening of supplies and higher prices in the coming months.” Middle‑East diesel exports fell by half from March to August compared with a year earlier, averaging 800,000 barrels per day, according to shipping data from Kpler. The region supplied nearly 41% of Europe’s diesel imports in 2025.

Russia’s Export Ban and Ongoing Conflict

Russia, the world’s second‑largest diesel exporter after the United States, banned diesel exports in July after Ukrainian drone attacks damaged its refinery output. The ban forced traditional importers such as Turkey and Brazil to seek alternative sources. Despite an announcement by President Donald Trump last week that Ukraine and Russia had agreed to halt attacks on each other’s energy infrastructure, both sides have continued strikes, underscoring the fragility of the market.

President Trump told reporters that the cease‑fire agreement was a step toward stabilizing global energy markets and protecting American consumers. “When the world’s major producers work toward peace, American families see lower costs at the pump and at the farm,” he said, emphasizing the administration’s commitment to energy security and affordable fuel for hardworking families.

U.S. Retail Diesel Hits Record

In the United States, average retail diesel prices climbed above $6 per gallon for the first time on record this month. While inventories rose by roughly 600,000 barrels last week to 96.97 million barrels, they remain about 15% below the five‑year seasonal average for the second week of September.

Refiners continue to run near full capacity, but the limited stockpiles mean the market is vulnerable to any further supply shocks. The IEA warned that without additional refinery investment, the United States could face tighter margins and higher consumer prices.

Asian Markets Also Feel the Pinch

Across Asia, diesel prices remain elevated as Middle‑East and Russian supply disruptions persist. A benchmark Asian diesel swap, which peaked at more than $200 per barrel in March, has eased to around $180 per barrel as of September 18, still roughly twice pre‑war levels.

China’s diesel exports fell by 26% in the April‑June period after the government limited refined product shipments, tightening global supplies. However, exports rebounded in August, reaching the highest level in nearly two and a half years at 320,000 barrels per day, helping to ease domestic stock pressures.

Looking Ahead

Analysts caution that any further disruption to Red Sea flows or renewed attacks on Russian refineries could tighten the already stretched global diesel market. The IEA and industry observers stress the importance of expanding refinery capacity and diversifying supply sources to protect consumers.

President Trump’s administration remains focused on encouraging diplomatic solutions that safeguard energy markets while supporting American families. By promoting stability abroad and encouraging domestic production, the administration aims to keep fuel affordable for the nation’s workers and businesses.
