India’s real GDP growth of 7.8 per cent in the April-June quarter of 2026 has triggered a sharp debate after former Finance Secretary Subhash Chandra Garg questioned the figure. He argued that a downward revision of the previous year’s GDP made the latest growth rate look stronger than it actually was. A closer look at the data and the methodology shows where that argument goes wrong.
The Claim and the Numbers
Garg pointed out that nominal GDP for the first quarter of 2025-26 had earlier been reported at around 86 lakh crore rupees. In the latest release, the same quarter appears closer to 80 lakh crore rupees under the revised series. Comparing the new first-quarter figure for 2026-27 (approximately 88.27 lakh crore rupees) with the old 86 lakh crore rupees number produces nominal growth of roughly 2.6 per cent. After adjusting for inflation, he suggested, real growth would be close to zero.
The arithmetic is straightforward. The error lies in treating the two figures as directly comparable.
Why the Base Year Change Matters
In early 2026 India shifted the base year for national accounts from 2011-12 to 2022-23. A base-year revision is a periodic statistical exercise. It updates the weights of different sectors, incorporates newer data sources, improves coverage of emerging activities and aligns methods with current international practice. Once the new series is introduced, historical estimates are recalculated on the same basis so that growth rates remain consistent over time.
The original 86 lakh crore rupees figure belonged to the old 2011-12 series. The 80 lakh crore rupees figure is the comparable estimate under the new 2022-23 series. The latest quarter’s GDP is also calculated on the new series. Growth rates are valid only when both the current and the previous period are measured on the same series. Mixing an old-series level with a new-series level produces a meaningless percentage.
Under the new series, the comparable year-ago nominal GDP is about 80 lakh crore rupees. Measured against that consistent base, nominal growth is around 10 per cent and real growth is the reported 7.8 per cent after deflation.
Standard Practice, Not Manipulation
Rebasing always changes the absolute levels of past GDP. Sometimes the revised levels are higher; sometimes they are lower, depending on how the structure of the economy and the new data sources alter the picture. The important point is that growth rates are recomputed on the revised levels so that the time series remains coherent. This is how national statistical offices around the world handle base-year changes.
Officials from the Ministry of Statistics and Programme Implementation have stated that the revision was the mechanical result of moving to the new series and of incorporating updated price indices and other indicators. They have rejected the suggestion that the previous year’s number was deliberately lowered to inflate the current growth rate.
Supporting Evidence Beyond the Headline
High-frequency indicators have been cited in support of the official growth estimate. Goods and services tax collections, bank credit growth and automobile sales, among other measures, pointed to reasonable economic momentum during the quarter. While no single indicator perfectly mirrors GDP, the broader data flow is not consistent with near-zero real growth.
That does not mean every aspect of the new series is beyond discussion. Economists routinely debate the choice of deflators, the treatment of the unorganised sector and the pace at which new data sources are integrated. Those are legitimate technical conversations. They are different from the claim that simply restoring an old-series level would reveal the “true” growth rate.
What the Controversy Reveals
The episode highlights two recurring features of India’s GDP discourse. First, base-year revisions inevitably create temporary confusion because absolute levels shift while the public conversation focuses on growth percentages. Second, political and public debate often seizes on the most dramatic arithmetic comparison rather than on whether the comparison is statistically valid.
Garg’s intervention correctly drew attention to the scale of the revision. Where it went wrong was in treating figures from two different statistical frameworks as interchangeable. Once the numbers are placed on a consistent series, the 7.8 per cent real growth rate is the coherent result of the data as currently constructed.
Looking Ahead
Future quarterly releases will continue to be published on the 2022-23 base. As more data accumulate, further routine revisions to recent quarters are normal. The credibility of the series will rest on transparency about methods, timely clarification when large revisions occur, and the willingness of users to distinguish between legitimate statistical updates and claims of deliberate distortion.
The 7.8 per cent figure is not immune to scrutiny. Growth accounting, sectoral inconsistencies and the relationship between GDP and employment or investment remain open for analysis. But the specific assertion that the rate would have been only 2.6 per cent in nominal terms, or near zero in real terms, rests on an invalid comparison across two different GDP series. On a like-for-like basis, the reported growth rate stands as the statistically consistent measure of the quarter’s performance.
