India to Use Producer Price Index [PPI] for GDP Deflation

 India to Use Producer Price Index [PPI] for GDP Deflation

• Announced by: Ministry of Statistics and Programme Implementation July 2026.[MoSPI]
• Change: Use output Producer Price Index as deflator for quarterly and annual GDP estimates, replacing Wholesale Price Index [WPI] wherever applicable.
• PPI Series: Released by DPIIT in June 2026 to support improved GDP measurement and align national accounts with international standards.
• Highlights:
  • GDP Deflation: Output PPI will be used for GDP deflation to improve accuracy of real growth measurement and reduce distortions.
  • Data Point June 2026: WPI inflation rose to 9.87% from 9.68% May, output PPI inflation increased to 9.57% from 9.38%.
  • Methodology Change: Revised GDP series updated base year to 2022-23 from 2011-12 and adopted double deflation which separately adjusts output and input prices.
  • Replacement: WPI phased out as GDP deflator, CPI will continue for specific granular items; earlier single deflation using WPI for output and input replaced due to growth estimation distortions.
  • Implementation: New PPI-based methodology with GDP estimates for April-June quarter 2026-27. Back series data also to be released.
• About PPI: Measures price changes received by producers for goods and services, used for accurate GDP deflation.
• About WPI vs PPI: WPI measures wholesale prices, includes taxes, multiple counting; PPI measures producer prices, excludes taxes, better for deflation.
• UPSC Relevance: GS3 - Economy, GDP measurement, Inflation indices, National Accounts.
• Prelims Point: Double deflation method - separately deflates output and intermediate consumption.
