Essential upgrades: On upgrades to India's statistical databases

📌 Summary:

• The government has rolled out wide-ranging, long-overdue upgrades to India's statistical databases — covering GDP, the Index of Industrial Production (IIP), and price indices (CPI, WPI, PPI) — making them more representative and aligned with international best practice

• Core change is updating base years: earlier base years were 2011 or 2012, leaving measures increasingly out of touch with reality

• In Feb 2026 MoSPI released the new national accounts/GDP series (base 2022-23) with methodological gains, including the double-deflator approach long demanded by statisticians and the IMF

• MoSPI also released a new CPI series (base 2024) with a more inclusive item basket and accurate weightages → more realistic retail inflation reading, which is central to interest-rate decisions

• New IIP series (base 2022-23) released in early June feeds into more accurate GDP

• The Commerce Ministry updated the WPI (new series) and introduced a Producer Price Index (PPI) to replace WPI within five years; PPI is the developed-economy standard and captures goods AND services prices at the producer stage

• A more accurate CPI/WPI yields a better GDP deflator → more reliable real (inflation-adjusted) GDP growth

• These are expected to improve the recurring 'C' grade the IMF gives India's national accounts; the editorial urges a time-bound release of the long-delayed new Census
