Diesel Prices Surge as Global Supply Crisis Looms

64/gallon—just 3/10 of a cent below the April 6 peak. The recovery reflects escalating geopolitical tensions in the Strait of Hormuz and a fundamental market imbalance: global crude supply has fallen by approximately 15 million barrels per day, while inventory drawdowns are accelerating despite demand declining by 5 million barrels per day in Q2. This paradox—shrinking demand coupled with record inventory depletion—signals that the worst of the supply crisis is yet to come. According to S&P Global Energy analysis, the cumulative supply loss now approaches 1 billion barrels, a volume that existing inventories cannot indefinitely absorb.

The firm projects global petroleum liquids demand will decline by 2 million barrels per day annually in 2026, the largest such decline since the COVID-19 pandemic. Critically, even with this demand contraction, supply losses are outpacing consumption reductions, creating structural upward pressure on prices. A prolonged Strait of Hormuz closure would require a minimum of seven months to restore upstream production once reopened, potentially extending the supply crisis into late 2026 and beyond. For supply chain and logistics professionals, this creates an urgent operational and financial planning challenge.

Fuel surcharges—already elevated—will likely continue climbing in the near term. Carriers and shippers must reassess transportation budgets, explore alternative routing strategies, and consider demand management tactics. The duration and severity of this disruption suggests this is not a cyclical price spike but a structural market shift requiring strategic adjustments to procurement, modal selection, and inventory positioning.
