Revision of Wholesale Price Index (WPI)


The Committee of Secretaries (CoS) in its meeting held on 9th August, 2010 approved the release of new series of Wholesale Price Index (WPI) with 2004-05 as its base and directed that it may be released on September 14, 2010. Accordingly WPI new series is proposed to be released tomorrow. Simultaneously, the release of the current series of WPI with 1993-94 as its base will be discontinued. Some of the broad features of new series of WPI are as follows:


· A representative commodity basket comprising 676 items has been selected and a new weighting diagram reflecting the current structure of the economy has been derived for the new series.


· The number of quotations selected for collecting price data for the above items is 5482. Thus, there is substantial increase in the number of items in the commodity basket and number of quotations for collecting price data in comparison to the existing series.
