Why Record Crude Output Can’t Solve America’s Diesel Crisis

Key Points:

• The U.S. is on track to produce a record 13.8 million barrels of crude oil per day in 2026, yet diesel prices have hit record highs due to unusually low distillate inventories expected to remain below the five-year range through much of 2027.
• Diesel shortages persist because crude oil must be refined into diesel, gasoline, and other products, and refineries have limited flexibility to adjust product yields due to chemical, equipment, and operational constraints.
• U.S. refineries are operating near full capacity (around 96%), with limited idle capacity and some reduction in total refining capacity, making it difficult to increase diesel output despite high crude production.
• The diesel supply crunch is global, influenced by export restrictions and disruptions in the Middle East, Russia, and China, as well as declining refining capacity in Europe, which increases competition and prices in the global refined product market.
• Restricting U.S. diesel exports could lower domestic prices short-term but may disrupt refinery economics and global supply chains; the core issue remains low inventories which reduce market resilience amid seasonal demand and geopolitical tensions.
