How the new GDP series could alter growth figures

DATA FACTORS

NATIONAL STATISTICAL OFFICE (NSO) released the advance estimates for 2025-26, indicating annual GDP growth of 7.4%, with a decadal growth of 5.9% (2015-2026).

The growth is fairly robust, given the need for structural changes, global uncertainties and pandemic. This would be the last GDP estimates of the current series based on 2011-12 since in February 2026, the statistics ministry proposed to release new series with 2022-23 as base.

There are three key critical concerns, besides the dated base, that are expected to be addressed in the new series to make these estimates more realistic. We look at these concerns and their outcomes. Firstly, the new base proposes to use supply use tables (SUT) for eliminating the discrepancies in GDP estimates based on sector approach and the expenditure approach. SUT is available until 2022-23, the base year for the new series.
