The federal government on Wednesday sought to handle considerations over the methodology and interpretation of the most recent gross home product (GDP) estimates, notably the damaging implicit deflator for manufacturing, holding that it is because enter costs elevated quicker relative to output costs.
Implicit worth deflator (IPD) is a measure of the general change in costs used to transform between nominal and actual GDP. The statistics ministry asserted there was no deliberate downward revision of June quarter GDP of FY26 to “mechanically enhance” the Q1FY27 progress price to 7.8 per cent.
Below the double-deflation strategy, output and intermediate consumption of the manufacturing sector are deflated individually and actual gross worth added (GVA) is obtained as actual output minus actual intermediate consumption.
Due to this fact, when enter costs enhance quicker than output costs, the relative worth motion may end up in nominal GVA rising extra slowly than actual GVA, Ministry of Statistics and Programme Implementation (Mospi) stated in a press assertion.
“In Q1, 2026-27 manufacturing GVA is compiled utilizing the double-deflation strategy, underneath which output and intermediate consumption are individually deflated. Throughout this era enter costs elevated quicker relative to output costs. Consequently, nominal GVA progress for this sector was comparatively decrease at 7.7 per cent, whereas actual GVA progress was 9.2 per cent,” Mospi stated in an announcement.
“The ensuing distinction between nominal and actual GVA progress produced a damaging implicit GVA deflator of 1.5 per cent,” the ministry stated.
Former performing chairman of the Nationwide Statistical Fee (NSC) P.C. Mohanan stated a damaging GVA deflator is more likely to occur whereas utilizing double deflation. “That is one motive why individuals weren’t very eager on double deflation earlier. A few of us had additionally raised the problem of how these indices (deflators) had been ready. The methodology remains to be not very clear,” he added.
Madan Sabnavis, chief economist at Financial institution of Baroda stated the Mospi clarification is supported by the company outcomes. “A variety of firms absorbed the upper enter prices and didn’t go them on to shoppers within the Q1 as a result of demand circumstances had been unsure. However at some stage, firms should go on the rise in enter costs,” he added.
Mospi secretary Saurabh Garg stated at a press convention that the ministry will launch the methodology and information sources used within the publication ‘Sources and Strategies’ in subsequent two week.
Mohanan stated Mospi ought to have waited earlier than shifting from utilizing WPI to PPI as a deflator. “Sudden adjustments will all the time create doubts within the minds of the information customers. They need to have waited for the PPI sequence to stabilise and research the behaviour of those indices for an affordable interval earlier than leaping into utilizing that,” he added.
On the problem raised by some specialists that final 12 months’s nominal GDP has been revised down from ~86 trillion to ~80 trillion, to make present 12 months’s GDP look higher, Mospi stated successive revisions to the GDP sequence arose from the change in base 12 months, incorporation of improved information sources and methodologies, and updation of accessible indicators.
“It’s subsequently incorrect to interpret the distinction as a deliberate downward revision of final 12 months’s GDP to mechanically enhance the present 12 months’s progress price,” it stated.
It additionally clarified that because the Quarterly GDP estimates are compiled utilizing the benchmark-indicator strategy, underneath which the motion within the quarterly estimates is guided by the motion in related high-frequency indicators, a revision within the previous-year benchmark doesn’t, by itself, create a synthetic enhance within the present 12 months’s underlying financial exercise or the symptoms used for estimation.
Questions have additionally been raised on 2.5 per cent implied GDP deflator when client inflation (CPI) was 3.9 per cent and wholesale inflation (WPI) was over 9 per cent.
The Mospi clarified that the implicit GDP deflator needn’t transfer in step with both CPI or WPI resulting from variations in protection, weights, worth ideas.
“It must be famous that the deflation of particular person merchandise/group of things is completed utilizing the related worth indices for that merchandise/item-group. The implicit GDP deflator is simply a derived quantity reflecting the value impression of greater than 300 particular person worth deflators used on the merchandise/item-group degree,” it added.
On excessive degree of discrepancies in each present and fixed worth GDP estimates throughout Q1 of FY27, Mospi stated whereas the present discrepancy might change in subsequent revision rounds, it can’t be concluded upfront that GDP will essentially be revised upward, or by a particular magnitude.
“The discrepancy is a statistical balancing merchandise arising from the distinction between the GDP estimates compiled via the manufacturing and expenditure approaches. Its motion ought to subsequently not be interpreted, by itself, as proof that the reported GDP is discreet or overstated,” it added.
India’s GDP methodology has come underneath cloud at a number of occasions. Within the final occasion, finance minister Nirmala Sitharaman clarified in Parliament final December that IMF’s ‘C’ score for India’s nationwide accounts’ information adequacy was on account of the usage of the 2011-12 base 12 months reasonably than any broader information shortcoming. India launched the 2022-23 base 12 months this 12 months.
