Wholesale Price Index

As India shifts to a new WPI base year, the outgoing series reflects a turbulent period marked by deep deflation, record inflation and sharp fuel price swings

The revised WPI expands the basket from 697 to 957 items, and improves the methodology to prepare weightings by using gross value of output instead of net traded value

The government will gradually phase out the Wholesale Price Index (WPI) and introduce a detailed Producer Price Index (PPI) covering output, input and services prices, in a bid to offer a more realistic assessment of inflationary trends in the economy. Addressing media on the subject, Praveen Mahto, Principal Economic Adviser in the Commerce and Industry Ministry, also said that the Department for Promotion of Industry and Internal Trade (DPIIT) will release the revised series of WPI with new base year 2022-23 on June 15, which would replace the existing series with base year 2011-12. In addition, the department would release a new series of Output Producer Price Index (OPPI), Trial Input Producer Price Index (IPPI), and Service Producer Price Index (Service PPI) of seven services - Banking, Securities Transaction, Insurance, Management of Pension Funds, Railways, Air (Passenger), and Telecom with base year 2022-23 on June 15.

Over financial years 2017-2026, the volatility of WPI, measured by standard deviation, was almost three times higher than that of CPI, according to the rating agency

The increased rate of inflation in March was primarily due to a jump in prices of crude petroleum & natural gas, other manufacturing, non-food articles, manufacture of basic metals and food articles

Committee asks DPIIT to align WPI with revised GDP, CPI and IIP series, and roll out producer price indices to improve price measurement and data accuracy

As India shifts its GDP base year to 2022-23, economists are divided on whether the unrevised WPI base will distort real growth estimates, even as CPI has been updated to 2024

India's revamped GDP series will use richer data and double deflation to better capture the informal economy, address IMF concerns and improve accuracy from 2026
