Port Congestion Removes 1.7M TEU from Global Shipping

Global port congestion is creating a structural capacity shortage, with Sea-Intelligence reporting that 1.7 million TEU of container shipping capacity is effectively unavailable due to delays and schedule disruptions. This represents a significant increase from pre-pandemic norms, where delays absorbed only 2.2% of global capacity. The congestion stems from multiple converging factors: climate-driven operational disruptions, the challenge of accommodating larger vessel calls at existing port infrastructure, and compounding schedule delays that cascade through shipping networks.

For supply chain professionals, this dynamic creates a persistent headwind for cost management and service reliability. When capacity is absorbed by delays rather than productive cargo movement, shippers face higher rates, longer transit times, and reduced schedule predictability, even as the nominal vessel supply appears adequate. This represents a hidden tax on logistics that affects margin management across industries and elevates the need for buffer inventory and flexible sourcing strategies.

The longer-term implication is that port infrastructure modernization and climate adaptation have become competitive imperatives. Carriers and port operators investing in congestion mitigation now will capture market share and customer loyalty as supply chains increasingly compete on reliability, not just cost.
