War Adds to US Supply Chain Uncertainty, Impact Not Drastic Yet

Why It Matters

The combined effect of conflict‑driven routing changes, carrier surcharges and pending tariffs signals rising import costs, pressuring retailer margins and potentially feeding higher consumer prices.

Key Takeaways

• POLB Q1 2026 TEU down 7% YoY despite leading US port
• Ocean carriers begin passing surcharges to shippers amid Middle East conflict
• FMC challenges new carrier surcharges, urging transparency for importers
• NRF warns tariffs and Section 122 could reignite import cost volatility
• Federal funds via WRDA and HMT support harbor dredging and capacity

Pulse Analysis

The ongoing conflict in the Middle East is reshaping maritime routes, forcing vessels to skirt contested waters. This detour raises fuel consumption and extends transit times, which in turn lifts ocean freight rates. While the Port of Long Beach still leads U.S. container traffic, its first‑quarter throughput fell about 7 % year‑over‑year, a modest dip that reflects the early stages of cost pass‑through. Retailers have so far absorbed higher expenses, but the cumulative effect of elevated freight and fuel prices is already nudging inflationary pressures, especially in categories sensitive to shipping costs.

At the same time, ocean carriers are introducing a suite of surcharges to recoup the added operational burden. The Federal Maritime Commission has stepped in, questioning the transparency and justification of these fees and urging carriers to provide clear breakdowns. This regulatory push aligns with the National Retail Federation’s call for predictable cost structures, as retailers seek to avoid surprise price spikes. Adding complexity, the Supreme Court’s recent reversal of 2025 tariffs leaves the door open for new Section 122 duties, which could reignite import‑cost volatility and force firms to reassess pricing strategies.

Looking ahead, retailers appear cautiously optimistic, maintaining healthy inventory levels ahead of the summer selling season. However, the convergence of geopolitical uncertainty, potential tariff reinstatements and evolving port infrastructure funding—through the Water Resources Development Act and Harbor Maintenance Tax—means supply‑chain managers must stay vigilant. Investments in dredging and channel upgrades aim to preserve capacity, but any further disruptions could compress margins and ultimately be passed on to consumers, underscoring the importance of proactive risk management in today’s volatile trade environment.
