The index for September was revised strongly upwards from 113.4 to 116.3, partly due to the good performance of Chinese ports whose data were still missing in October. The October flash forecast is based on solid sample of 37 ports handling roughly 73% of the traffic represented in the index.
The Index is based on data for 72 international ports covering more than 60% of world container handling. These ports are continuously monitored by the ISL as part of their market analysis. Because large parts of international merchandise trade are transported by ship, the development of port handling is a good indicator for world trade. As many ports release information about their activities only two weeks after the end of the respective month, the RWI/ISL Container Throughput Index is a reliable early indicator for the development of international merchandise trade and hence for the activity of the global economy.
The RWI/ISL Container Throughput Index for November will be published on December 20th.
