New Delhi: The government has sought to clear the air over two issues surrounding the latest GDP numbers — a seemingly puzzling negative 1.5 percent inflation in manufacturing and the revision of last year’s April-June GDP from about Rs 86 lakh crore to Rs 80.32 lakh crore.
The clarification comes after questions were raised over the credibility and interpretation of the newly released GDP estimates for the first quarter of 2026-27, in which India's real GDP growth was estimated at 7.8 percent.
In a detailed explanation, the Ministry of Statistics and Programme Implementation (MoSPI) said both issues arise primarily from the way national income is calculated and from revisions made when a new GDP series is introduced.

One of the most confusing numbers in the latest GDP data is the minus 1.5 percent implicit GVA deflator for manufacturing.
At first glance, this could suggest that prices of manufactured goods actually fell. The government, however, says that is not what the number means.
To understand this, it is important to distinguish between the price of what a factory sells and the price it pays for inputs such as raw materials.
Manufacturing GVA is calculated using what economists call a double-deflation method. In simple terms, the government separately adjusts the value of a factory's output and the cost of the intermediate goods it uses to produce that output before arriving at real GVA.
So, if the prices of raw materials and other inputs rise faster than the prices of finished products, a factory may see its nominal GVA grow more slowly than its real GVA.
That can produce a negative GVA deflator — even when neither the price of the finished product nor the price of the inputs has actually fallen.
The government's own illustration makes the point. If a manufacturer's sales value rises 20 percent but its input costs rise 22 percent, the nominal value added can grow much more slowly than the underlying real value added after prices are adjusted.
In the actual April-June quarter, manufacturing's nominal GVA grew 7.7 percent, while its real GVA increased 9.2 percent, resulting in the reported negative 1.5 percent implicit GVA deflator.
The government said this phenomenon was seen in activities including textiles and cotton ginning, basic metals, and rubber and plastic products, where input prices rose faster than output prices.
For the common man, the simplest way to understand it is: a negative manufacturing deflator does not mean that the prices of cars, steel, clothes or other manufactured products necessarily fell. It means that, in the GDP calculation, input prices moved differently from output prices.
Agriculture is calculated differently at the quarterly level.
According to the government, agricultural GVA is first estimated at constant prices based on production data. Current-price GVA is then derived by applying the relevant Producer Price Index.
During April-June 2026, the output Producer Price Index for agriculture, forestry and fishing increased by about 5 percent. Since agricultural output prices rose, agriculture recorded a positive implied inflation rate of 3.9 percent.
Thus, the apparent contrast between manufacturing's minus 1.5 percent and agriculture's plus 3.9 percent does not mean that manufacturing prices fell while agricultural prices rose. The two sectors use different methods to arrive at their quarterly GVA estimates.
The second issue is more consequential because it concerns the base against which the latest GDP growth is measured.
When the Q1 GDP estimate for 2025-26 was originally released in August 2025 under the then-prevailing 2011-12 base-year series, India's current-price GDP was estimated at Rs 86.05 lakh crore.
But after the government introduced a new GDP series with 2022-23 as the base year in February 2026, the estimate for the same quarter was revised to Rs 80.32 lakh crore.
That is a difference of nearly Rs 5.7 lakh crore.
The government has rejected the suggestion that this reduction was made to make the latest GDP growth rate look better.
Its explanation is that the GDP series is routinely revised when better data becomes available and when methodology, coverage and base-year information are updated. The new series incorporated updated data sources and new price and production indices, including the Output Producer Price Index and Banking Services Price Index.
This is where GDP mathematics can become confusing.
GDP growth is essentially a comparison between the economy's performance in one period and the corresponding period a year earlier. Therefore, if the estimate for the previous year changes, the percentage growth calculated against it can also change.
The government, however, argues that changing the benchmark does not change the underlying economic activity that took place last year.
It has also pointed out that quarterly GDP estimates are not based on a single number or a single survey. They use a benchmark-indicator approach, drawing on hundreds of indicators such as crop production, cement output, finished steel consumption and commercial vehicle sales.
In other words, when the government revises the GDP number for the previous year, it is not necessarily saying that factories produced less or that Indians consumed less than previously thought. Rather, it is saying that with better information and a revised statistical framework, its estimate of the size of the economy has changed.
So, did the government ‘reduce’ GDP to boost growth?
The government's answer is no.
It says the reduction in the Q1 2025-26 current-price GDP estimate from Rs 86.05 lakh crore under the old series to Rs 80.32 lakh crore under the new series is a consequence of the base-year change, methodological improvements, better data and successive revisions.
Importantly, the government is not saying that Rs 86.05 lakh crore was deliberately inflated earlier or that Rs 80.32 lakh crore is the result of an arbitrary reduction. Rather, the two figures belong to different versions of the GDP series.
This distinction is important when comparing the numbers.
The latest clarification essentially boils down to three points:
A negative 1.5 percent manufacturing deflator does not mean manufacturing prices fell. It reflects the fact that input prices rose faster than output prices under the double-deflation method.
The Rs 86 lakh crore to Rs 80.32 lakh crore revision does not, by itself, mean that the economy suddenly became smaller. It reflects a revised statistical framework and updated data.
The 7.8 percent real GDP growth for Q1 FY27 is calculated using the revised GDP series, which the government says is intended to provide a more accurate picture of the economy.

The larger takeaway is that GDP is an estimate, not a single cash register recording every rupee generated in the economy. It is periodically revised as better information becomes available. The latest controversy is therefore less about whether the government can revise GDP — it routinely does — and more about whether the new methodology and resulting estimates provide a sufficiently transparent and reliable picture of economic activity.
The government's latest FAQ is essentially an attempt to explain that statistical machinery in simpler terms and address concerns arising from the unusually large revision in the previous-year current-price GDP and the negative manufacturing deflator.
