India’s unexpectedly strong economic growth has triggered a debate over the reliability of the country’s newly revised GDP data, with a former senior finance ministry official and an ex-central bank governor questioning whether the headline expansion overstates underlying momentum.
India’s economy grew 7.8% in the three months through June from a year earlier, government data showed on Monday, significantly exceeding the 7.1% median forecast in a Reuters poll. The expansion was supported by an investment boom and strong manufacturing activity, alongside resilient consumer demand.
The reading has nevertheless raised questions over how much of the acceleration reflects genuine economic strength and how much is the result of changes to the way India calculates GDP.

Subhash Chandra Garg, a former senior Finance Ministry bureaucrat, argued in Indian media that the growth rate was inflated because the government had lowered its estimate of GDP for the same quarter a year earlier, creating a weaker base against which the latest expansion was measured.
Raghuram Rajan, the former governor of the Reserve Bank of India, raised a different concern, questioning why such robust GDP growth has not been accompanied by stronger job creation, domestic investment and foreign portfolio inflows.
Some private-sector economists have also focused on the GDP deflator, the measure used to remove price changes from nominal GDP and calculate real economic growth. They argue that the unusually low deflator may be understating inflation and consequently overstating real output growth.
The controversy has given India’s opposition another line of attack against Prime Minister Narendra Modi’s government. A senior Congress party official dismissed the 7.8% figure as “statistical gymnastics,” turning what initially began largely as a social-media debate into a broader political dispute over the government’s economic record.
The government has faced growing pressure over employment and economic opportunity, particularly among younger Indians. Youth protests in July contributed to the resignation of the education minister and were widely seen as reflecting broader frustration over jobs, opportunities and corruption in the education system.
Government Defends Revised GDP Methodology
India’s statistics ministry responded by holding a news conference on Wednesday to defend the GDP figures and rebut Garg’s criticism.
A senior statistics official said the methodology changes introduced in February followed extensive consultation and were designed to provide a more accurate picture of economic activity.
The revised series changed the GDP base year by more than a decade and incorporated new data sources as well as changes in the goods and services captured by the national accounts.
One of the most consequential changes was the revision of nominal GDP for April-June 2025. Under the new methodology, the figure was reduced to 80 trillion rupees ($850 billion), compared with 86.05 trillion rupees under the previous GDP series. Using the old base would have produced nominal GDP growth of only 2.6% in the latest quarter, compared with the 10.3% reported under the new series.
But the government has rejected a direct comparison between the two figures, explaining that the new series does more than simply change the base year. It also incorporates revised data sources, coverage and methodology, meaning the old and new estimates are not directly comparable.
The statistics secretary said quarterly revisions over the past three years had moved in both directions, while changes to annual GDP estimates had been relatively limited.
The government’s defense is deemed necessary because GDP revisions are a normal part of national accounting. Updating the base year and incorporating better data can change the measured size and composition of an economy without necessarily implying that the underlying activity itself has suddenly changed.
The Deflator Becomes The Key Battleground
The more difficult question concerns prices.
India’s GDP deflator for April-June was just 2.3%, considerably below retail inflation of more than 4% and wholesale inflation of more than 9%. Because real GDP is calculated by stripping price changes from nominal output, the choice of deflator can materially affect the reported growth rate. A lower deflator means a larger portion of nominal growth is treated as an increase in real economic activity.
The government says the apparent gap does not indicate that inflation has been understated. It argues that the revised GDP series uses the internationally accepted method of double deflation, which separately adjusts the value of output and the cost of inputs for changes in prices.
The statistics secretary said the new system also relies on a more granular Producer Price Index, using more than 300 deflators covering inputs and outputs, compared with about 180 under the previous methodology.
That approach can produce a GDP deflator that differs significantly from consumer or wholesale inflation because the three measures capture different baskets and stages of the economy. Consumer inflation, for example, measures prices faced by households, while GDP deflation reflects the prices of domestically produced goods and services and their contribution to national output.
But that has not ended the debate.
Mumbai-based ICICI Securities Primary Dealership said the lower GDP deflator was compatible with an environment in which input prices were rising faster than output prices. In that interpretation, the unusually low deflator does not necessarily invalidate the growth figure.
Societe Generale economists took a more cautious view, noting that the low deflator raises questions about the strength of real-sector activity.
Other Indicators Provide Mixed Evidence
India’s high-frequency economic data offers ammunition to both sides of the debate, although several indicators support the government’s broader argument that economic activity remains strong.
Auto sales increased 21% in August, while bank credit growth reached a decade-high 19%. Net direct tax revenue also increased more than 23% year-on-year during the April-August period, pointing to strong activity and income generation in parts of the economy.
Those indicators make it difficult to dismiss the GDP figures as purely a statistical phenomenon.
At the same time, the Purchasing Managers’ Index, a closely watched survey-based gauge of business activity, has weakened to multiyear lows. That contrast underpins why economists remain divided over the extent to which India’s headline GDP growth is translating into broad-based economic momentum.
The disagreement also goes beyond the technical details of national accounting. The central economic question is whether India’s rapid headline growth is generating sufficient employment, investment and capital inflows to support sustained expansion. Rajan’s criticism goes directly to that issue. If output is expanding at close to 8% but employment, private investment and foreign capital flows are not accelerating proportionately, the headline number may not fully capture the quality or breadth of growth.
For the Modi government, the stakes are higher than defending a single quarterly statistic. India is seeking to sustain rapid growth while attracting investment, expanding manufacturing and creating enough jobs for a large and increasingly young workforce.
The latest figures provide evidence that the economy retains considerable momentum. But the dispute over the methodology means investors and policymakers are likely to scrutinize other indicators more closely before concluding that India’s underlying growth rate has genuinely shifted higher.
Ultimately, the credibility of the new GDP series will depend less on any single quarterly number than on whether its estimates continue to align over time with employment, investment, tax receipts, corporate activity, consumption and other independent measures of economic performance.
