India is planning to release a revised GDP series with 2022-23 as the base year on February 27, 2026, replacing the current 2011-12 base. Officials are considering incorporating findings from the upcoming All India Debt and Investment Survey (AIDIS), scheduled from July 2026 to June 2027, into the GDP series by FY28. This survey is crucial for estimating household investment and could lead to further updates in the national accounts, particularly if post-pandemic shifts in savings and investment behavior are significant.
