ITS Logistics May Port/Rail Ramp Freight Index: Strait of Hormuz Closure Sends Fuel Shock Through Supply Chains

Why It Matters

The fuel shock and routing disruptions are compressing margins for carriers and inflating shipping costs, forcing a rapid mode‑shift that could reshape North American intermodal logistics.

Key Takeaways

• Strait of Hormuz closure drives diesel to $5.64/gal, raising freight costs
• U.S. oil product exports hit record 8.2 M bpd, boosting Gulf port activity
• Transatlantic container rates jumped 46% since April, straining carrier capacity
• Spot truck rates near all‑time highs as enforcement cuts available trucks
• Shippers shift drayage to rail, risking inland ramp congestion

Pulse Analysis

The geopolitical tension around the Strait of Hormuz has rippled through global supply chains, turning diesel into a premium commodity at $5.64 per gallon. This price spike not only inflates truck operating costs but also forces ocean carriers to absorb higher bunker fees, prompting a steep rise in container freight rates—46% on trans‑Atlantic lanes and 22% on trans‑Pacific routes since April. At the same time, the United States has stepped in as a backup oil supplier, pushing weekly oil product exports to a record 8.2 million barrels per day and energizing Gulf‑Coast terminals such as Corpus Christi, which reported a 30% surge in export volumes.

Domestically, the confluence of higher fuel costs and the Commercial Vehicle Safety Alliance’s International Roadcheck has tightened truck capacity. With 31.4% of inspected vehicles taken out of service, spot market rates have climbed toward historic highs, squeezing shippers’ budgets. Meanwhile, containerized imports slipped 3.2% month‑over‑month to 2.28 million TEUs, with the West Coast bearing the brunt of reduced China‑origin shipments and elevated trans‑Pacific freight. The Port of Los Angeles bucked the trend, posting its second‑best April on record, likely due to carrier strategies like blank sailings that concentrate volume at a single gateway.

Facing sustained cost pressure, many shippers are rebalancing their logistics footprints, shifting drayage and long‑haul truck moves to rail to capture diesel savings. This modal pivot, while financially prudent, threatens to overload inland rail ramps and create new congestion points for intermodal traffic. As rail capacity tightens, the industry may see a secondary bottleneck that mirrors the current trucking squeeze, prompting carriers and logistics providers to invest in rail‑focused infrastructure and digital scheduling tools. The evolving dynamics underscore a broader strategic imperative: supply‑chain leaders must diversify mode options and enhance real‑time visibility to navigate a freight environment defined by fuel volatility and geopolitical uncertainty.
