Context: Recently, the National Statistical Commission (NSC) has been scrutinizing the working group report outlining the roadmap for introducing the Producer Price Index (PPI) in India as a replacement for the Wholesale Price Index (WPI), and we are eagerly awaiting their recommendations.

oPPI is different from WPI in the way that it measures the average change in prices received by producers and excludes indirect taxes.

Wholesale Price Index (WPI)

  • About: The WPI is a gauge used to monitor and record fluctuations in the prices of bulk goods at the wholesale level within India.
  • Published by: Office of Economic Adviser, Ministry of Commerce and Industry.

  • Component of WPI: Manufactured products = 65% approx (64.2% now)

oPrimary articles = 20% approx (22.6% now)

oFuel and power = 15% approx (13.1% now)

Producer Price Index (PPI)
