What specific events caused diesel prices to spike to record levels?

The spike is driven by two primary factors: military tensions in the Middle East affecting transit through the Strait of Hormuz (which handles critical oil shipments), and Ukrainian drone strikes on Russian refining infrastructure. Russia's refining sector is heavily oriented toward middle distillates such as diesel, so outages there have constrained global supply. These factors combined have compressed supply at a time when U.S. refineries are running at near-maximum capacity.

How much have diesel prices increased in recent months?

According to AAA data cited in the article, diesel rose approximately $2.10 per gallon from March 1 (when prices were $3.758/gallon) to the current record. Over the past month alone, ULSD futures prices climbed from $3.7705/gallon on August 4 to settlement levels above $4.68/gallon by mid-September—a roughly 25% increase.

Is this price increase likely to be temporary or structural?

Industry analysis suggests a structural rather than temporary shift. While futures prices have softened slightly (down 12 cents from intraday highs), energy analyst Kevin Book expressed skepticism about rapid price declines even if Middle East supply reopens, citing infrastructure questions on the supply side and ongoing constraints from Russian refinery outages. A full normalization is not expected in the near term.

How does this compare to historical diesel price peaks?

The current $5.85/gallon retail price breaks through the previous all-time high of $5.82/gallon set in June 2022 following Russia's invasion of Ukraine. CME ULSD futures also hit near-record levels at $4.6822/gallon settlement on Wednesday, representing the highest prices since at least 2022 (with possible outliers exceeding this in prior years).

What should logistics companies do in response?

Supply chain teams should immediately review fuel surcharge mechanisms in contracts, assess opportunities for modal optimization or route consolidation to reduce mileage, evaluate supplier diversification to spread transportation risk, and model scenarios around extended high-fuel-cost environments. Renegotiating customer contracts with updated fuel escalators and reviewing pricing strategies are also critical near-term actions.

The signal

82/gallon set in June 2022. 85/gallon on Friday, driven by a convergence of geopolitical disruptions including military escalation in the Middle East affecting the Strait of Hormuz, combined with sustained damage to Russian refining capacity from Ukrainian drone strikes. 10 per gallon since early March, with the most dramatic acceleration occurring in the past month.

For supply chain professionals, this represents a structural cost shock affecting the entire transportation and logistics sector. Diesel represents a significant component of trucking costs, and at current levels, carrier profitability is under severe pressure. The root causes—geopolitical instability and infrastructure damage—suggest this is not a temporary blip but a medium-to-long-term headwind.

Industry experts indicate that even if the Strait of Hormuz reopens, recovery may be gradual due to infrastructure constraints and the difficulty of quickly restoring Russian refining capacity. Companies must reassess fuel surcharge mechanisms, consider modal shifts where feasible, and evaluate sourcing strategies that account for higher transportation costs. The duration and severity of this shock warrant immediate scenario planning around procurement policies, pricing strategies, and customer contract negotiations.

What This Means for Your Supply Chain

Simulation Suggestion

immediate

What if diesel prices remain above $5.50/gallon for the next 6 months?

Model the impact of sustained high diesel costs on trucking economics, carrier margins, and cost-per-mile metrics. Simulate how supply chain networks need to adapt through modal shifts (rail where feasible), consolidation strategies, and pricing adjustments to customers. Assess which regional supply chains are most vulnerable.
