Surjit Bhalla Rejects India GDP Data Manipulation Claims Amid Controversy

In a significant development concerning India's economic statistics, prominent economist and former IMF Executive Director for India, Surjit Bhalla, has strongly rejected claims alleging political manipulation of the country's Gross Domestic Product (GDP) data. Bhalla asserted that his analysis found "no evidence" that politics played a role in the recent revisions of India's GDP numbers. He made these remarks during a discussion on the controversy surrounding India's revised GDP figures, which have triggered questions over methodology, rebasing, and earlier estimates. Bhalla even described such criticism as "the stupidest" levelled against India's economic policymaking. He further defended India's statistical establishment, characterizing the economists and statisticians involved in compiling national accounts as among the "most conservative" he had encountered. This debate gained traction following the release of India's Q1 FY27 (April-June 2026) GDP estimates, which showed a real growth of 7.8% and a nominal growth of 10.3%. The Ministry of Statistics and Programme Implementation (MoSPI) subsequently issued clarifications regarding its methodology, particularly the adoption of a new base year (2022-23) and the use of the double-deflation method. A central point of contention raised by critics, including former Finance Secretary Subhash Garg, was the downward revision of last year's GDP numbers. Garg initially claimed that India's real GDP growth for Q1 FY27 would be only 2.6%, arguing that the government purposely reduced the previous year's GDP figure (from ₹86.05 lakh crore under the old 2011-12 base year to ₹80 lakh crore under the new series) to artificially inflate the current year's growth rate. However, this comparison was widely criticized as "misleading" and "fundamentally flawed" by MoSPI and other economists, as it inappropriately compared figures from two different GDP series with distinct base years and methodologies. Later, Garg himself contradicted his earlier claim, stating that India is "definitely growing by 5%". Another aspect of the controversy involved the negative 1.5% implicit Gross Value Added (GVA) deflator for manufacturing in Q1 FY27. MoSPI clarified that a negative deflator does not indicate a fall in manufacturing prices. Instead, under the double-deflation approach, real GVA is calculated by separately deflating output and intermediate consumption. When input prices rise faster than output prices, nominal GVA can grow slower than real GVA, resulting in a negative implicit GVA deflator, even if both output and input prices are increasing. This is a standard national accounts method recommended by the International Monetary Fund (IMF). Former Chief Statistician of India, Pronab Sen, while not directly accusing manipulation, raised concerns about the new GDP series' methodology, particularly regarding the price deflators. He suggested that the Q1 GDP growth figure of 7.8% might be an overestimation, with an actual figure closer to 6.5%. Sen also emphasized the importance of transparency and urged the National Statistics Office (NSO) to publish both the old and new GDP series with their respective bases for at least five years to allow for better comparison and understanding of the changes. He highlighted that a significant downward revision in nominal GDP for FY26 under the new series, compared to earlier estimates, was largely a "price thing" linked to the overall inflation taken being on the lower side. Bhalla, in his defense of the data, pointed out that India's statistical office has, in its last two GDP data revisions (2011-12 and 2022-23), actually revised its own economy smaller, which is uncommon in the developing world. He contrasted this with countries like Bangladesh, Pakistan, China, and Vietnam, which have shown much larger cumulative GDP additions through base-year changes since 1980. He noted improvements in India's statistical system, such as the abolition of single deflation and the introduction of Producer Price Indices (PPI), which the IMF had previously requested. Overall, the news highlights an ongoing, intricate debate among economists and policymakers in India regarding the accuracy and methodology of GDP calculations. While the government and some economists like Surjit Bhalla defend the integrity of the data and the updated methodologies, others like Pronab Sen continue to call for greater transparency and scrutiny of the underlying data and its implications.
