The Container Throughput Index of the RWI – Leibniz Institute for Economic Research and the ISL - Institute of Shipping Economics and Logistics showed a further substantial increase in September 2017 from 128.5 to 129.7 (revised figures). Compared to the beginning of 2017 it gained almost six points. A similarly strong plus was last achieved in 2010. The figure for August was revised downward by 0.3 points compared to the flash estimation.
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 September is based on data reported by 45 ports, accounting for close to 80% of the total index volume.
The RWI/ISL-Container Throughput Index for October 2017 will be released on 21 November 2017.
