Port and inland congestion now exceed ship capacity as supply chain chokepoints

The global supply chain has undergone a fundamental shift in its primary constraint. For years, maritime shipping capacity dominated discussions of supply chain risk, with vessel availability and ocean freight rates serving as key performance indicators. However, the article highlights that infrastructure limitations at ports and throughout inland logistics networks—including rail, trucking, and warehousing—now represent the more significant bottleneck limiting trade throughput. This structural change reflects both the lingering effects of pandemic-era congestion and the inadequacy of port and inland terminal infrastructure to handle modern container volumes.

For supply chain professionals, this represents a critical pivot in risk management strategy. Companies can no longer assume that securing ocean freight capacity guarantees on-time delivery; final-mile timing now depends heavily on port dwell times, rail terminal availability, and inland transportation capacity. This has profound implications for inventory positioning, safety stock policies, and demand planning, particularly for just-in-time operations that depend on reliable downstream connectivity. The findings underscore the growing importance of end-to-end supply chain visibility and the need for companies to invest in inland logistics partnerships and multimodal transportation strategies.

Shippers must now balance ocean routing decisions against downstream port and inland handling capacity, rather than optimizing primarily on ocean freight economics. This represents a structural challenge that may persist for years, requiring strategic investments in alternative corridors, modal diversification, and closer collaboration with 3PLs and port operators.
