The Export and Import Price Indices (XMPI) are measures of price changes of goods imported into or exported outside the country. The XMPI are used to analyse Terms of Trade (ToT) which is the ratio of Export Price Index (XPI) to the Import Price Index (MPI).
The Export and Import Price Index (XMPI) covers both exports and imports of merchandise trade. These quarterly specification-based XMPI have been compiled and disseminated since the first quarter of 2013 up to the last quarter 2017 with reference base period of March quarter 2013. The updated XMPI has the fourth quarter of 2017 as the reference base period. The updating of the weights and the product sample for the XMPI used customs data for the years 2014 to 2016. Initiation of price collection for the updated XMPI was carried out during the period October-December 2017. This allows for the compilation of the XMPI for the fourth quarter of 2017 using the new product and enterprise samples.
