New GDP series captures structural changes in economy, reflects global best practices: N K Singh
The new GDP series with base year 2022-23 (replacing base year 2011-12) was released by the National Statistics Office (NSO) on February 27, 2026
The revised series is described as reflecting structural changes in the economy and as being aligned with global best practices in national accounting
Commentary on the revision linked it to India's recent sovereign credit rating upgrade, describing the improvement in India's rating as coming after a multi-decade gap since India last held an "A"-grade rating
The revised base year captures shifts in economic activity such as digitalization and formalization of enterprises
GDP Base Year Revision — Purpose and Process
The base year in national accounts is the reference year against which real (inflation-adjusted) GDP growth is measured; it also anchors the weights and methodology used to compile GDP. Periodic revision is necessary to capture structural changes in the economy, incorporate new and improved data sources, and update survey/deflator methodology. India's base year has moved through several revisions: 1999-2000, 2004-05, then 2011-12, and now 2022-23.
Defenses of the revision emphasize that base-year changes are a routine, globally practiced statistical exercise undertaken to reflect a changing economic structure, not a one-off or India-specific departure from norms.
Alignment with the UN System of National Accounts (SNA) 2008
The System of National Accounts (SNA) is the UN-endorsed international statistical standard that defines how countries compile GDP and related aggregates for cross-country comparability. The 2008 update to SNA introduced changes such as treating research and development expenditure as capital formation and refined measurement of financial intermediation services.
Key Details
- The new GDP series is stated to align with SNA 2008 recommendations
- Uses a new Producer Price Index (PPI)-based deflator series in place of parts of the earlier Wholesale Price Index-based approach
- MoSPI is the nodal ministry; the National Statistical Office (NSO) compiles the estimates under the oversight framework that includes the National Statistical Commission
Aligning with SNA 2008 makes India's GDP data more internationally comparable and methodologically current — a data-quality improvement of the kind that sovereign rating agencies cite as strengthening confidence in a country's macroeconomic statistics.
Institutional Machinery for National Accounts Statistics
GDP compilation in India runs through a defined institutional chain: MoSPI sets policy and constitutes expert committees; the NSO carries out data compilation and release; advisory bodies like ACNAS recommend methodological changes such as base year selection.
Key Details
- ACNAS (2024): 26 members drawn from central ministries, state governments, academia, and research institutions
- Base year decisions of this kind have historically been made through similar advisory committee structures for past revisions (e.g., 2011-12 base year)
The institutional process — an expert advisory committee formally recommending a base year, followed by NSO implementation — is the standard governance route through which national accounts revisions of this scale proceed in India.
- New GDP series base year: 2022-23 (previous base year: 2011-12)
- Release date: February 27, 2026 (annual and quarterly estimates for 2022-23 to 2025-26)
- ACNAS constituted: June 2024; 26 members; chaired by Biswanath Goldar
- Back-series data (linked to 1950-51): expected by December 2026
- Methodological alignment: UN System of National Accounts (SNA) 2008; new Producer Price Index (PPI) series
- Referenced rating context: India's sovereign rating upgraded to A- by JCRA (from BBB+), described as ending a multi-decade gap (reported as roughly 35-38 years by different sources) since India last held an "A"-grade sovereign rating
