RWI/ISL Container Throughput Index

Since early 2012, the Institute of Shipping Economics and Logistics (ISL) and the RWI – Leibniz-Institut für Wirtschaftsforschung (RWI) are publishing a monthly index for global container throughput which aims to provide reliable conclusions on short term trends in worldwide economic activity. The RWI/ISL Container Throughput Index uses the fact that international trade is primarily handled by ships and containers, which means the container throughput in ports is an important indicator of global trade. Currently, the database consists of 82 international ports covering more than 60% of world container handling. These ports are continuously monitored by the ISL as part of their market analysis.
