The government will introduce a revised Wholesale Price Index (WPI) series and a new Producer Price Index (PPI) series from 15 June 2026, with PPI set to replace WPI over the next five years.
The Department for Promotion of Industry and Internal Trade (DPIIT) will release the revised WPI with 2022–23 as the new base year, replacing the 2011–12 series.
The new Producer Price Index (PPI) will include Output PPI, Input PPI, and Services PPI to better measure producer-level inflation.
Initially, the Services PPI will cover seven sectors, including banking, insurance, railways, air passenger transport, and telecom.
WPI will continue to be published alongside PPI for five years before being phased out.
