5.4% is the world average growth rate of trade in goods, in volume,  over the period 1996-2004. This figure is to be compared with the 6.9% growth rate of world trade in value across this period. This suggests a yearly 1.5% increase in international trade prices, which is lower than the average world inflation (5% increase in consumption prices, according to the IMF).

Nevertheless, the following graph shows that the gap between value and volume evolutions is widening at the end of the period. From 2002, international trade looks less and less disinflationary. Probably, one of the main reason of this price increase being the pressure on primary good markets involved by emerging countries.

TradePrices allows us to do this volume calculations. TradePrices is the new database of international trade price indices, relying on unit values of the international trade database BACI. TradePrices is available on line and provides several type of index, for 205 countries and 35 sectors over the period 1996-2004.
