Impending US Diesel Shortage Threatens Supply Chains by August 2026
New York, Wednesday, 3 June 2026.
Goldman Sachs warns US diesel inventories could plummet to a critical 20-day supply by August 2026, risking severe supply chain disruptions and reigniting inflation across the broader economy.
The Anatomy of a Historic Drawdown
Over the past eight weeks leading up to early June 2026, the United States has witnessed the largest historical decline in its oil inventories [1][2]. This unprecedented drawdown has left domestic diesel stocks at their lowest point since 2003 [1][2]. During the week ending May 31, 2026, U.S. crude inventories plunged by 6.8 million barrels, or 1.08 million cubic meters, marking the sixth consecutive week of such declines [1]. Consequently, by the week ending May 22, 2026, the nation’s diesel supplies had already dwindled to approximately 28 days of inventory, representing a sharp contraction of -22.222 percent from the 36 days recorded at the end of January 2026 [2].
Refining Margins and the Cost to Consumers
This structural scarcity has dramatically inflated the cost of diesel, sending shockwaves through the American industrial sector [GPT]. Since late February 2026, the average retail price of diesel in the U.S. has surged 45 percent, eclipsing $5.43 per gallon, or approximately $1.43 per liter [2][4]. The economic toll is already materializing in corporate earnings; for instance, heavy machinery manufacturer Deere & Co. explicitly cited soaring fuel and fertilizer costs as the primary driver behind sluggish tractor sales in May 2026 [2].
