India’s economy grew 7.8 percent in the April-June quarter, according to the latest official GDP data. The number was better than expected and was hailed by the government as evidence of India’s resilience amid global economic uncertainty.
But the headline figure has quickly become the centre of a political and statistical controversy.
Former finance secretary Subhash Chandra Garg has questioned the way the latest growth number is being presented, arguing that a sharp downward revision to last year’s GDP has significantly lifted the apparent growth rate for the current quarter.
The government, however, says the comparison being made by Garg is invalid because the figures belong to different GDP series. It says the revision is a routine consequence of shifting the base year, incorporating newer data and improving the methodology used to calculate national income.
The dispute has now drawn in the Congress, Prime Minister Narendra Modi, Commerce and Industry Minister Piyush Goyal and former RBI Governor Raghuram Rajan.
The controversy centres on nominal, or current-price, GDP.
Under the earlier 2011-12 base-year series, Q1 FY2025-26 GDP at current prices was estimated at around ₹86.05 lakh-crore. Under the new GDP series, with 2022-23 as the base year, the same quarter’s estimate has been revised to around ₹80 lakh-crore.
That is a difference of roughly ₹6 lakh crore.
Garg argues that if the earlier ₹86.05 lakh crore figure had been retained, the latest Q1 FY2026-27 nominal GDP of about ₹88.27 lakh crore would imply growth of only around 2.6 percent.
In other words, his argument is not that the government has officially reported 2.6 percent GDP growth. Rather, he is questioning how much of the reported growth is explained by the downward revision to the previous year’s base.
Garg has also pointed to the fact that the earlier Q1 FY2025-26 estimate was produced under the old GDP series, while the latest comparison is being made using the new series.
The government has rejected the criticism, calling the comparison between ₹86.05 lakh-crore and ₹88.27 lakh-crore misleading.
Its argument: growth rates must be calculated using comparable estimates from the same GDP series.
The ₹86.05 lakh-crore figure was calculated under the old 2011-12 base-year series. After India shifted to the 2022-23 base year, the entire historical GDP series was recalculated.
Under the revised series, Q1 FY2025-26 GDP at current prices was initially estimated at ₹80.32 lakh-crore. It was subsequently updated to ₹80.44 lakh-crore and later revised to around ₹80 lakh crore as newer data became available.
The government says these revisions reflect:
Change in the GDP base year from 2011-12 to 2022-23
Updated data sources
Changes in methodology and coverage
Incorporation of newer economic indicators
Revised Index of Industrial Production data
Introduction of the Producer Price Index
Therefore, the government says the appropriate comparison is ₹88.27 lakh-crore in Q1 FY2026-27 against the revised Q1 FY2025-26 figure of around ₹80 lakh-crore — not against the superseded ₹86.05 lakh crore estimate.
A GDP base-year revision is not simply an accounting adjustment to make one quarter look better or worse.
When the base year changes, statisticians revisit the historical GDP series using newer information about the structure of the economy.
The government says the latest revision incorporates improved data sources, updated methodologies and wider coverage of economic activity.
This means that a figure published under the old series cannot necessarily be placed alongside a figure from the new series to calculate a meaningful growth rate.
That is the government's central defence against the 2.6 percent argument.
However, the controversy highlights an important issue: when a revised GDP series substantially changes the previous year's nominal GDP, it can also alter how the latest growth performance is perceived.
The Congress has seized on Garg's criticism to attack the Modi government.
Congress general secretary Jairam Ramesh shared a video of Garg and accused the government of using public relations to present a better picture of the economy.
The Kerala Congress also joined the criticism, using an image comparing the economy with liquid in a beer mug and the official GDP figures with the fizz on top.
The political argument is essentially this: even if the 7.8 percent figure is statistically valid under the new series, it may not fully reflect the economic experience of households and businesses.
The government has strongly rejected this interpretation. Prime Minister Narendra Modi described the 7.8 percent growth as a “Herculean feat”, while Piyush Goyal accused critics of failing to make comparable comparisons.
Former RBI governor Raghuram Rajan has also expressed doubts about the strength of the headline growth numbers, although his criticism is different from Garg's calculation.
Rajan's focus is on jobs. He questioned why an economy growing at such a rapid pace is not generating enough good jobs for young people.
His argument raises a broader economic question: if GDP is expanding rapidly, why is that growth not translating into stronger employment opportunities and broader economic gains?
This does not by itself disprove the official GDP figures. But it highlights the difference between measuring aggregate output and assessing the quality and distribution of economic growth.
There are two separate issues in the current GDP controversy. The first is statistical: whether the 7.8 percent growth rate has been correctly calculated under the new GDP series. The government's position is that it has.
The second is economic: whether the headline number adequately captures the strength of the economy and whether revisions to earlier data have materially changed the picture.
That is where Garg, Rajan and the Opposition are raising questions.
The 2.6 percent figure, therefore, should not be presented as an alternative official GDP growth rate. It is a calculation based on comparing the latest nominal GDP with an earlier estimate from a superseded GDP series.
At the same time, the controversy cannot simply be dismissed as a political attack. Large revisions to historical data naturally invite scrutiny, particularly when they have a significant effect on the apparent pace of growth.
For now, the official number remains 7.8 percent. The real debate is over how much confidence should be placed in that headline figure — and what it says about the economy beyond the statistical tables.
