Context: Govt. to replace Wholesale Price Index with Producer Price Index
India is modernising its inflation and economic statistics framework. The Wholesale Price Index base year has been revised from 2011–12 to 2022–23, while a new Producer Price Index has been introduced. WPI and PPI will run simultaneously for five years before PPI gradually replaces WPI.
