The Container Throughput Index of the RWI – Leibniz Institute for Economic Research and the Institute of Shipping Economics and Logistics (ISL) continues its upward tendency as it improves from 127.9 (revised figure) to 128.8 points in August 2017. Values for the previous two months have been adjusted to a greater extent than usual. This was necessary due to an outlier in the data of one of the major ports in the index. The revised figure for June is now much closer to the one originally reported while the value for July has been revised downwards by 0.7 points compared to the one previously stated. However, the general economic tendency of the index has not been affected by these adjustments.
The index is based on data continuously collected from world container ports by ISL as part of its market monitoring. 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. Together, the 82 ports covered in the index account for about six out of ten containers handled worldwide. The flash estimate for August is based on data reported by 41 ports accounting for roughly 78% of the total index volume.
The RWI/ISL-Container Throughput Index for September 2017 will be released on October 26th.
