RWI/ISL Container Throughput Index reaches new heights

Press release from 22 August 2017

The Container Throughput Index of the RWI – Leibniz Institute for Economic Research and the ISL – Institute of Shipping Economics and Logistics rose in July 2017 from 127.4 (revised figure) to 128.6 and reached a new all-time high. At the same time there were upward revisions – for the May value slightly and for the June value significantly. All of these figures indicate a rather strong expansion of the world trade.

Container Throughput Index

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 July is based on data reported by 41 ports, accounting for close to 73% of the total index volume.

The RWI/ISL-Container Throughput Index for August 2017 will be released on September 26th.
