The Singapore Department of Statistics has completed the rebasing of the Import Price Index and Export Price Index to base year 2006. The rebasing of these indices is conducted periodically to ensure that the coverage of commodities and the weighting structure of these indices are representative of the current imports and exports patterns. In the 2006 rebasing exercise, methodological changes were introduced to enhance the accuracy of the price indices and facilitate the early completion of the 2006 rebasing exercise.

The information paper titled "Rebasing and Revision of Import & Export Price Indices (Base Year 2006 = 100)" (230kb) provides an overview of the concepts, methodology and survey coverage of the 2006-based price indices. A comparison of the weighting patterns and trends of the 2006-based price indices with those of the 2000-based series is also presented.
