💡 Why It Matters
Accurate GDP deflator figures are essential for separating real economic growth from price changes. SBI’s confirmation lends credibility to the 7.8 percent growth print, reassuring investors, policymakers and the public that the data is reliable and transparent.
Background In July, the Ministry of Statistics and Programme Implementation (MoSPI) released India’s growth figure for the June quarter, reporting a 7.8 percent rise in GDP. The figure was higher than many analysts had expected, prompting questions about the accuracy of the newly adopted GDP deflator methodology.
SBI Research’s Independent Verification State Bank of India’s research arm, SBI Research, conducted its own calculation of the GDP deflator for the first quarter of fiscal year 2027 (Q1 FY27). Using publicly available data on crop prices, wholesale indices and service‑sector output, the bank produced deflator estimates that closely mirror the government’s numbers.
### Agriculture SBI’s estimate of agricultural GVA‑deflator inflation is 3.74 percent, compared with the MoSPI‑implied 3.77 percent. The calculation incorporated crop price data and separate estimates of rising costs for fertiliser and diesel.
### Industry For the manufacturing sector, SBI reported a deflator of –1.67 percent, versus the government’s –1.30 percent. The negative figure reflects a scenario where input costs rose faster than the prices manufacturers could charge for finished goods.
### Services The services sector deflator was 2.30 percent, just 0.10 percent lower than the government’s 2.40 percent estimate.
### Overall Economy When combined, SBI’s overall GDP deflator stands at 3.70 percent, against the official 3.00 percent. The slight difference is attributed to the methodology’s weighting of sectoral deflators.
Significance of the Findings SBI’s exercise demonstrates that the new deflator methodology can be replicated with publicly available data, addressing concerns that the revised calculation was opaque. By confirming the government’s figures, the bank reinforces confidence in the 7.8 percent growth print.
Reactions and Commentary Some former officials had previously questioned the validity of the higher growth figure, citing the lack of transparency in the new deflator calculation. SBI’s report counters this by showing that the broad contours of the methodology are reproducible. The bank also dismissed comparisons between the old and new deflator series as “frivolous,” noting that such comparisons do not account for the change in how activity is measured.
What to Watch - Future revisions of the GDP deflator methodology may invite further scrutiny from analysts and former officials. - The Ministry may release additional data to support the new calculation, potentially clarifying any remaining doubts. - Market reactions to the confirmed growth figure could influence investment sentiment and policy decisions.
Conclusion SBI Research’s independent calculation provides a reassuring check on the government’s GDP deflator and supports the 7.8 percent growth figure for Q1 FY27. The exercise underscores the importance of transparency and reproducibility in national economic statistics.
🏛️ Background & Context
India’s GDP deflator methodology was revised in 2023 to better capture sector‑specific price movements. The change aimed to improve the precision of real growth estimates but raised concerns about data accessibility and reproducibility.
