What is the current ocean freight rate differential between US coasts?

According to Drewry's World Container Index as of September 10, 2026, the spot rate differential stands at USD 2,374 per FEU, with Shanghai to Los Angeles at USD 7,352 and Shanghai to New York at USD 9,726. Xeneta data from late August recorded an even wider spread of USD 3,334 per FEU.

When does West Coast routing become cost-competitive for inland destinations?

The article indicates that when ocean freight savings of USD 2,300 to USD 3,300 per FEU are factored against rail and drayage costs, West Coast routing remains attractive even for Midwest destinations. The exact breakeven point depends on specific inland destinations and current drayage rates, but the savings can be significant after accounting for inland transport.

What factors are driving the rate gap widening?

Three primary factors: (1) Panama Canal restrictions including reduced draft limits and fewer daily Neopanamax slots, (2) Red Sea security concerns forcing carriers to use longer Cape of Good Hope routes for East Coast service, and (3) US Section 301 tariff expansions of 10 to 12.5 percent on several product categories, prompting shippers to cut ocean freight costs to protect margins.

Are US ports ready to absorb more West Coast volume?

The article notes significant concerns about West Coast capacity. While West Coast gateways handled 43.9 percent of total US imports in August 2026, all 10 top US container ports recorded increased transit delays. The article explicitly raises the question of whether West Coast ports can handle additional volume without creating further delays and higher inland transport costs.

How do US import volumes compare historically?

August 2026 containerized imports reached 2.6 million TEU, representing the third-highest monthly volume in US history. This trails only May 2022 (2.622 million TEU) and July 2025 (2.621 million TEU), and stands 21.5 percent higher than pre-pandemic baseline volumes. China accounts for 34 percent of total US imports, with Southeast Asian origins showing double-digit gains.

The signal

A significant widening in ocean freight rates between US coasts is fundamentally altering import routing decisions for US-bound containerized cargo from Asia. The direct ocean rate differential now stands at approximately USD 2,374 per FEU (forty-foot equivalent unit), with Shanghai to Los Angeles at USD 7,352 versus Shanghai to New York at USD 9,726, creating sufficient savings to justify inland rail and drayage transport to Midwest destinations.

This shift is driven by three structural factors: Panama Canal draft restrictions limiting all-water East Coast capacity, Red Sea security risks forcing carriers toward longer Cape of Good Hope routings, and US tariff expansion prompting shippers to reduce ocean freight costs. Simultaneously, August 2026 US containerized imports reached 2.6 million TEU, the third-highest monthly volume on record, generating both capacity pressure and routing flexibility across the port system.

Frequently Asked Questions

What This Means for Your Supply Chain

Simulation Suggestion

this month

What if West Coast ports experience 15 percent congestion increase from mode shifting?

Simulate a scenario where increased routing to West Coast ports due to rate differentials causes facility congestion at Los Angeles, Long Beach, and Oakland to increase by 15 percent over the next 8 weeks. Model resulting dwell time increases, inland transport cost impacts, and breakeven analysis on West Coast versus East Coast routing. Compare service levels and total delivered costs.

What if Section 301 tariffs increase to 25 percent, accelerating import pull-forward?

Simulate a tariff escalation scenario where US Section 301 duties increase from current 10 to 12.5 percent to 25 percent on additional product categories. Model resulting surge in import volumes during current month and next month, capacity impacts across both coasts, and optimal routing strategies given compressed service windows. Compare modal mix and inland transport availability.

What if Panama Canal restrictions ease and rate differential compresses to USD 800?

Model the impact of potential Panama Canal capacity improvements reducing the ocean rate differential from current USD 2,374 per FEU to USD 800 per FEU. Reassess the economic viability of West Coast routing for Midwest destinations given rail and drayage costs. Determine at what rate threshold shippers would revert to East Coast routing.
