Port performance moves to center of disruption risk
A new World Bank Group and S&P Global Market Intelligence report says container ports are no longer just casualties of supply chain disruption, but increasingly help determine whether shocks spread or are contained.
The Container Port Performance Index 2025 found that port performance and supply chain stress now move in both directions. External events such as the Red Sea crisis, extreme weather and shipping network disruption can weaken port performance, while inefficient ports can extend vessel delays and reduce effective fleet capacity.
The findings matter for carriers, forwarders, terminal operators and cargo owners because vessel time in port remains a core measure of supply chain reliability. Ships delayed at anchor or alongside terminals are unavailable elsewhere, reducing schedule integrity across liner networks.
Burst congestion challenges even modern ports
The report highlights the rise of “burst congestion,” where vessels arrive in clusters after delays, diversions or schedule disruption. Unlike congestion driven by steady cargo growth, these sudden arrival waves can strain berth planning, labor deployment and yard capacity even at well equipped ports.
Recent disruption in the Red Sea and the Strait of Hormuz has shown how quickly service networks can be unsettled. Rerouted or delayed vessels may arrive out of sequence, forcing ports to adjust berth windows and inland connections at short notice.
“Ports are not just passively exposed to external shocks; they also dynamically shape how those shocks are transmitted,” said Bertrand De la Borde, Global Director for Transport and Logistics at the World Bank Group. “They can either amplify disruptions or help contain them.”
Resilience, data and coordination gain weight
The report challenges the view that port performance is determined mainly by physical infrastructure. Cranes, deeper channels and terminal expansion remain important, but the index points to operational resilience, coordination and digitalization as increasingly decisive.
High performing ports tend to show predictable vessel turnaround times, strong coordination between authorities and terminal operators, effective data sharing and faster recovery after disruption.
Real time information on vessel arrivals, berth availability, yard conditions and landside transport can help ports act before congestion worsens. For shippers, that can influence demurrage, storage costs, inventory planning and contract reliability.
East Asian ports continued to dominate many of the top positions in the 2025 index. Ports in upper middle income economies, particularly in Asia, again outperformed many counterparts in wealthier markets, reflecting export intensity, competition and sustained investment.
North American and European ports continued to recover from pandemic era disruption, but the report said they remain exposed to congestion, labor constraints and hinterland bottlenecks.
The Middle East, previously among the strongest performing regions, saw weaker results after Red Sea related schedule disruption. The report cited vessel bunching and greater arrival uncertainty as key factors.
For policymakers and operators, the message is that port efficiency is becoming a resilience issue as much as a cost issue. Ports that can absorb shocks may help stabilize trade flows, while those that cannot may transmit delays across wider shipping networks.
“Efficient ports are not only a source of competitiveness,” the report said, “but also a key determinant of how well supply chains absorb and recover from disruptions.”
