What Happened
- The Ministry of Statistics and Programme Implementation (MoSPI) released a new series of National Accounts Estimates, shifting the base year from 2011-12 to 2022-23.
- Under the new series, India's real GDP is estimated to grow at 7.6% in FY26, with Q3 FY26 recording 7.8% growth; nominal GDP growth is pegged at 8.6%.
- India's nominal GDP for FY26 is estimated at Rs. 345.47 lakh crore — approximately 3.3% smaller than earlier estimates under the old series.
- The new series revises nominal GDP downward for FY24, FY25, and FY26 by about 3.8% each for earlier years, which will negatively affect fiscal ratios such as debt-to-GDP and fiscal deficit-to-GDP.
- Manufacturing posted double-digit growth for the fifth straight quarter, and services rose to a seven-quarter high of 9.5% under the new series.

National Income Statistics: Base Year Revision
In India, national income aggregates — GDP, GVA, NNP, and per capita income — are compiled by the National Statistical Office (NSO) under MoSPI. Periodically, the base year of these estimates is revised to reflect updated consumption patterns, production structures, and price levels. The previous base year of 2011-12, adopted in 2015, had become outdated after over a decade. The new base year of 2022-23 represents a post-COVID-19 normal year with robust and comprehensive data across sectors.
- Previous base year: 2011-12 (adopted in 2015, replacing the 2004-05 series)
- New base year: 2022-23 (adopted in February 2026)
- Compiled by: National Statistical Office (NSO), MoSPI
- MoSPI simultaneously revised base years for CPI and IIP alongside GDP in 2026
- Data sources expanded to include GST administrative data for estimating private corporate sector output
Connection to this news: The base year change underpins the revised GDP growth estimates and explains why India's nominal GDP appears smaller — the 2022-23 base better captures current price structures.
Double Deflation: The Key Methodological Upgrade
The most significant methodological innovation in the new GDP series is the adoption of double deflation for manufacturing and agriculture. Under the previous single-deflation method, a single price index was used to convert nominal GVA to real terms, which could distort real growth when input and output prices moved differently. Under double deflation, output and intermediate inputs are deflated separately using their respective price indices (WPI/CPI components), producing more accurate real value added estimates. This aligns India's methodology with the UN System of National Accounts (SNA 2025) and international best practices.
- Old method: Single deflation — one price deflator applied to the entire sector
- New method: Double deflation — outputs deflated separately from inputs (intermediate consumption)
- Sectors covered: Manufacturing and agriculture initially; single extrapolation elsewhere
- Price indicators used: Expanded from ~180 to nearly 500-600 specific CPI and WPI components
- GST data now used to cross-validate annual accounts and allocate GVA across states
Connection to this news: The shift to double deflation is why real growth figures under the new series differ from the old estimates — it produces more precise measurement of value added by eliminating the distortions of the single-deflator approach.
Fiscal Ratios and the GDP Denominator Effect
When the GDP denominator changes, all ratios expressed as a percentage of GDP are automatically affected. A downward revision in nominal GDP — as in the current base year change — increases the apparent fiscal deficit-to-GDP ratio and the debt-to-GDP ratio even if the absolute rupee values remain unchanged. This has significant implications for India's compliance with FRBM Act targets and how markets and rating agencies perceive fiscal consolidation.
- Fiscal Deficit (FY26 RE): 4.4% of GDP (under old series); ratio rises under the smaller GDP denominator
- Debt-to-GDP: FY26 estimated at ~56.1%; the downward GDP revision makes this ratio appear larger
- FRBM Act (2003) requires the government to target fiscal consolidation and maintain transparency through Medium-Term Fiscal Policy Statements
- NK Singh Committee (2017) recommended a debt-to-GDP target of 60% for combined government by 2023
Connection to this news: The article notes that India's nominal GDP has been revised downward, which will negatively impact several fiscal ratios — this is the denominator effect in action.
