Definition & Explanation
Port congestion occurs when a port receives more vessels, containers, or cargo than its available berths, cranes, storage areas, and workforce can handle in a timely manner. The clearest sign is a queue of ships riding at anchor outside the port, sometimes waiting several days before a berth opens up. The financial fallout – additional port dues, demurrage charges, and rerouting costs – hits carriers, freight forwarders, and shippers alike, with little room to negotiate relief. Typical triggers include post-holiday demand surges, severe weather events, labour disputes, and structural capacity shortfalls that can cascade across multiple ports in the same region. Unlike a localised bottleneck such as a single crane failure, port congestion disrupts the entire terminal operation and sends ripple effects through global supply chains.
