US West Coast ports are regaining container volume momentum after years of disruption and competitive pressure, but new analysis from the Pacific Merchant Shipping Association warns that the region still faces major challenges in rebuilding lost market share and restoring long-term supply chain competitiveness.
The report argues that US West Coast ports have yet to fully recover from years of cargo diversion, labour disruption concerns and intensifying competition from Gulf Coast and East Coast gateways. While Southern California ports have recently regained some growth momentum, the broader West Coast port system continues to face structural pressure as supply chains become increasingly diversified.
According to the Pacific Merchant Shipping Association, West Coast ports once dominated North American container trade thanks to their strategic positioning between Asian manufacturing hubs and the US consumer market.
However, the report says the region gradually lost part of this competitive advantage following the Great Recession as cargo owners sought alternative routing options and more resilient supply chain structures.
The analysis suggests that discretionary cargo flows have become increasingly competitive over the past decade, with importers prioritising reliability, inland logistics connectivity and risk diversification.
The shift accelerated during the pandemic-era congestion crisis and subsequent labour uncertainty on the US West Coast.
The report also highlights the growing importance of intermodal efficiency, infrastructure investment and operational reliability in determining future cargo flows.
While recent volume recovery is viewed as encouraging, the association argues that West Coast ports still face a “heavy lift” to regain the market share dominance they once held within North American container shipping.
