National Diesel Average Rises for the 14th Consecutive Week, Reports Energy Information Administration

Why It Matters

Diesel is the dominant cost for freight, so sustained spikes threaten trucking capacity, raise shipping surcharges, and could ripple through global supply chains.

Key Takeaways

• Diesel at $5.64/gal, 14th weekly rise.
• Annual increase exceeds $2 per gallon.
• Trucking capacity shrinking due to higher fuel costs.
• Maritime routes adding 11‑12 days via Cape.
• Fuel surcharges now over $1.25 per $1 diesel.

Pulse Analysis

The latest EIA data shows diesel hitting $5.643 per gallon, a level not seen since mid‑2022 and the 14th straight weekly climb. The rally mirrors a broader surge in WTI crude, now trading above $115 a barrel, and is amplified by heightened geopolitical risk after recent U.S. and Israeli strikes on Iran. While the headline number captures attention, the underlying drivers—tight global oil markets, refinery constraints, and speculative positioning—suggest the price pressure may persist longer than a typical seasonal bounce.

For the trucking sector, the impact is immediate and severe. Most large fleets operate near nine miles per gallon, yet many contracts lock shippers into rates based on six‑and‑a‑half mpg. The widening gap forces carriers to absorb an extra ten to fifteen cents per mile, prompting speed throttling and, more critically, a pullback in capacity as smaller operators lack the cash flow to cover rising fuel invoices. Fuel surcharges, now indexed to EIA prices, have jumped to over $1.25 for every dollar of diesel, eroding profit margins and reshaping contract negotiations across the industry.

Maritime logistics face a parallel shock. With diesel costs soaring, carriers are adding 11‑12 days to voyages that detour around the Cape of Good Hope, a route previously avoided due to higher fuel consumption. The added transit time inflates inventory carrying costs and pressures container pricing, already volatile from accessorial fees ranging $300‑$2,000. As fuel price volatility continues, the combined effect on land and sea freight could translate into broader inflationary pressures, underscoring the strategic importance of monitoring diesel trends for any supply‑chain stakeholder.
