China’s Covid Crises: The State of Chinese Port Congestion

April 27, 2022
China’s Covid Crises:  Impact of Lockdown on Chinese Ports

China's rising covid cases and lockdowns due to the omicron variant have been increasing the number of vessels waiting outside the country's ports. Initial lockdowns were placed on Shanghai, the country's largest city, from March 28 to April 5. However, authorities decided to extend this lockdown across Shanghai without providing a time frame for when it will end. This indefinite lockdown extension across Shanghai has had ripple effects on the number of vessels backed up along the country's coastline.

Shanghai's initial covid lockdown saw the number of vessels and average waiting days at its port increase. Consequently, shipping companies began to shift calls to neighboring ports as cargo exports out of Shanghai were also dropping.

Shipping companies omitting Shanghai calls have begun to impact congestion in neighboring ports. Data pulled from SeaVantage Port Insight Platform shows an increase in the daily average number of vessels anchored at Ningbo, Yantian, and Qingdao over the past 3 months. In particular, the number of vessels waiting outside Ningbo has more than doubled since February.

Meanwhile, SeaVantage's Port Insight Platform shows that congestion at the Port of Shanghai has decreased over the past two weeks due to vessels skipping Shanghai port calls due to low cargo export volumes.

Shanghai's port is currently not experiencing more congestion due to the lockdown, as other data may suggest. The coastline of Shanghai may be filled with many ships, but not all of them are headed for its port. Click here to see the list of vessels predicted to arrive at the port of Shanghai.
