Answer: 2022–23
Notes: The Government of India has revised the base year of the Wholesale Price Index (WPI) from 2011–12 to 2022–23. The revised WPI series and new Producer Price Indices (PPIs) will be released by the Office of Economic Adviser under the Department for Promotion of Industry and Internal Trade. New indices include Output Producer Price Index (OPPI), Input Producer Price Index (IPPI), and Service Producer Price Index (Service PPI). The transition from WPI to PPI aligns India’s statistical framework with international standards recommended by the International Monetary Fund. Both WPI and PPI will be released simultaneously for five years before WPI is phased out.
