War, Energy, and Trade Disruptions Reshape Global Supply Chain Dynamics; Diesel Hits $5.38 as Middle East Tensions Escalate

Tuesday, March 31, 2026

Today's developments reveal an intensifying convergence of geopolitical tensions and supply chain disruptions that demand immediate strategic responses from logistics professionals. The closure of the Salalah port following drone strikes, combined with broader Strait of Hormuz disruptions, is creating cascading effects across global shipping networks. This coincides with a dramatic spike in diesel prices to $5.38/gallon - the largest one-week increase ever recorded - driven by Middle East conflicts and a Texas refinery fire. Meanwhile, regulatory shifts are reshaping the competitive landscape, with the Court of International Trade expanding tariff refund eligibility and the FMC asserting stronger oversight of carrier surcharges. These developments signal a fundamental realignment of supply chain risk factors, where geopolitical events, energy costs, and regulatory changes are converging to force immediate operational adaptations across the logistics sector.

I

Drone Strike Closes Strategic Salalah Port Amid Escalating Middle East Transit Crisis

Key Middle East transit hub Salalah, operated by APM Terminals, has been closed following a drone strike. The port was serving as a critical alternative container drop-off point for carriers unable to transit the Strait of Hormuz.

Impact · Loss of Salalah port access further constrains already limited Middle East shipping options, forcing carriers to seek alternative routes and potentially causing significant delays and cost increases for regional cargo movements.

Action
Review and update contingency routing plans for Middle East cargo; consider alternative ports and factor in extended transit times and higher costs for Q2-Q3 operations.
II

Diesel Prices Surge to $5.38 in Historic Weekly Jump Amid Global Crisis

National diesel prices spiked 96 cents in one week - the largest increase since federal tracking began - reaching $5.38 per gallon from a March 1 baseline of $3.90, driven by Middle East tensions and a Texas refinery fire.

Impact · Unprecedented fuel cost increases will significantly impact transportation budgets and carrier operations, potentially leading to increased surcharges and service adjustments.

Action
Implement immediate fuel surcharge reviews and consider locking in fuel hedging strategies for Q2-Q3 to mitigate volatility risks.
III

Court Expands Tariff Refund Eligibility, Opening Door for Broader Claims

The Court of International Trade has amended its previous order to include all entries subject to certain Trump-era tariffs, expanding the scope of potential refunds to include finally liquidated entries.

Impact · Broader eligibility for tariff refunds could provide significant cost recovery opportunities for importers who paid duties during the affected period.

Action
Conduct immediate audit of all potentially eligible entries and prepare documentation for refund claims before any filing deadlines.
IV

FMC Blocks Carrier Surcharge Waiver, Signaling Stricter Oversight

The Federal Maritime Commission rejected carriers' request to waive the 30-day notice period for war-related surcharges, reflecting increased regulatory scrutiny and shifting power dynamics in shipping policy.

Impact · Strengthened regulatory oversight may limit carriers' ability to implement rapid pricing changes, potentially affecting contract negotiations and rate stability.

Action
Review all carrier contracts for surcharge provisions and develop strategies to address potential 30-day notice requirements in future agreements.

Watch for: 1) Expansion of alternative Middle East shipping routes and associated cost premiums through Q2, 2) Diesel price stabilization timeline following refinery repairs - estimated 45-60 days, 3) Carrier responses to stricter FMC oversight, particularly in surcharge implementations over next 30 days, 4) Deadline announcements for expanded tariff refund claims, 5) Development of new regional shipping hubs as alternatives to compromised Middle East ports.
