Indian Economy (UPSC): Why India is Phasing Out WPI for PPI, WPI Base Year Revision explained

భారతదేశ ద్రవ్యోల్బణం లెక్కింపులో భారీ మార్పులు.. WPI బేస్ ఇయర్ మార్పు & కొత్త PPI పూర్తి విశ్లేషణ | This comprehensive lecture analyzes the Government of India’s landmark 2026 decision to revise the Wholesale Price Index (WPI) base year to 2022–23 and introduce the Producer Price Index (PPI) framework, curated specifically for UPSC Civil Services Examination (Prelims & Mains) preparation. Using this foundational current affairs update, we break down core macroeconomic concepts under Indian Economy (GS Paper 3). We dissect how the new PPI architecture—consisting of Output PPI (OPPI), Input PPI (IPPI), and Service PPI—rectifies the structural limitations of WPI by tracking factory-gate prices and integrating services. Finally, we evaluate its technical significance for national income accounting, its role as a superior GDP deflator for converting Nominal GDP to Real GDP, and the logistics of the planned 2026–2031 five-year transition window recommended by global frameworks like the IMF.
