Abstract
The pattern of international trade is changing constantly. The HWWA Index of World Market Prices of Commodities, which is weighted by imports, therefore needs to be adapted from time to time in order to preserve its relevance as an indicator of price trends in international commodity markets. It is now (as of September 2003) published with updated weights based on 1999–2001 import values and with a new price basis (2000=100).
