951/gallon since early July. This spike directly impacts transportation costs across all supply chain sectors, with fuel surcharges affecting everything from trucking to last-mile delivery. However, late-week futures trading suggests temporary relief may be arriving, driven by potential diplomatic developments and reports of improved crude flow through critical chokepoints. P.
Morgan admit they cannot model. 7939 by mid-week, but remain elevated compared to historical norms. Meanwhile, policymakers are debating protectionist solutions—such as diesel export bans—that experts warn could backfire by tightening global markets and driving prices higher in import-dependent regions like the East Coast. For supply chain professionals, this translates to immediate pressure on transportation budgets and strategic uncertainty about fuel surcharge structures.
The volatility makes capacity planning difficult, forces renegotiation of freight contracts, and threatens refinery operations that have been running near full capacity. Supply chain teams must monitor both commodity futures and geopolitical developments closely, as diplomatic progress or escalation could swing fuel costs by tens of cents per gallon within days.
Frequently Asked Questions
What This Means for Your Supply Chain
What if Iran escalates and Strait of Hormuz flow drops 20%?
Model a scenario where geopolitical tensions worsen and crude oil flow through the Strait of Hormuz decreases by 20% from current levels. This would tighten global crude supply, potentially pushing ULSD futures back toward the $5.00-$5.50/gallon range and increasing diesel surcharges on all transportation costs.
Run this scenarioWhat if U.S.-Iran diplomatic talks succeed and crude prices drop 20%?
Model successful diplomatic resolution at the UN General Assembly resulting in de-escalation and restoration of normal crude flows. This scenario would ease Strait of Hormuz bottleneck, increase global supply, and push ULSD futures down toward the $3.50-$4.00/gallon range, reducing fuel surcharges across all transportation modes.
Run this scenarioWhat if a diesel export ban is enacted and global prices rise 15%?
Simulate the implementation of a U.S. diesel export ban that redirects 1.3+ million barrels/day to domestic markets. Model the resulting tightening of global diesel supplies, causing international prices to rise 15%, which boomerangs back to U.S. import-dependent regions (East Coast, West Coast) as refineries reduce operating rates and cut gasoline production.
