India's recent provisional estimate of 7.8% Gross Domestic Product (GDP) growth has ignited a fresh debate among economists and policymakers. While the Ministry of Statistics and Programme Implementation (MoSPI) defends the figures, former Chief Economic Advisor Arvind Subramanian has voiced concerns, emphasizing the critical need for greater transparency and trust in the nation's official economic data.
Subramanian, known for his incisive economic commentary, stated that while the 7.8% growth rate is "technically plausible" when analyzed under the new methodology, the government's inconsistent handling of economic data has eroded public confidence. This "trust deficit" makes even technically sound figures harder for independent economists and the public to accept fully.
Understanding the Plausibility and Concerns
In his assessment, Subramanian acknowledged that MoSPI is technically correct in stating that GDP estimates under the new and old methodologies are not directly comparable. When the new framework is applied consistently, the 7.8% real growth rate emerges. He also pointed to several coincident macroeconomic indicators that seem to support the possibility of robust economic activity, including:
- Real sales growth of listed firms at 14.9%
- Real non-food credit growth also at 14.9%
- Real exports growing by 12.1%
Despite these supporting indicators, Subramanian highlighted a more significant issue: the overall credibility of official data. He cited several instances that have contributed to this credibility gap, such as the prolonged delay in conducting the Census, the controversial withdrawal of the 2017 consumption survey, and general questions surrounding other official economic estimates. In such an environment, he argued, the onus is on the government to definitively prove the integrity and accuracy of its economic data.
Inconsistencies and the Energy Shock
Subramanian further questioned inconsistencies in the data, including a 7% downward revision of first-quarter FY2025-26 GDP when the methodology changed, and the lack of a comprehensive "back series" that would explain when and how any loss of growth occurred over time. He also noted a disconnect between the reported growth estimate and the prevailing economic conditions during April and May 2026.
“The latest numbers are plausible,” Subramanian said, “but restoring confidence will require the government to publish the underlying data and methodology and address the inconsistencies that continue to fuel doubts.”
During that period, India experienced significant fuel shortages and rationing, which severely impacted travel and businesses. The rise in energy costs effectively acted as an additional tax burden, estimated at around 1.5% of GDP. This challenging backdrop was compounded by tepid wage growth, weak job creation, a declining stock market, and pressure on the currency. Subramanian found it remarkable that, despite these headwinds, MoSPI's estimate suggested an acceleration of growth by nearly one percentage point, rather than merely maintaining previous rates.
Other points of concern raised included nominal net Goods and Services Tax (GST) revenue growing by only 5%, falling import volumes, and a negative manufacturing deflator, even as business margins reportedly improved.
Recommendations for Restoring Trust
To address these concerns and rebuild trust, Subramanian proposed several actions for the government:
- Provide a credible, research-backed explanation detailing how the economy managed to accelerate growth despite the significant energy shock and other adverse conditions.
- Offer clear explanations for the inconsistencies observed in nominal net GST revenue, import volumes, and the manufacturing deflator.
- Release the complete "Sources and Methods" document, which would transparently outline how GDP figures are calculated and revised.
- Apply the same rigorous logic and scrutiny used to defend the current GDP numbers to earlier estimates, particularly those from the previous 15 years, if current growth is supported by indicators like sales, trade, electricity, and investment.
Ultimately, Subramanian stressed that while the latest GDP figures might be technically sound, genuine public and expert confidence can only be restored through comprehensive transparency, consistent methodology, and a willingness to address all lingering doubts with detailed, verifiable data.
