India’s industrial growth in August: India’s industrial output grew 8% in August, its strongest year-on-year expansion in recent months, as manufacturing and electricity output accelerated. Manufacturing, which accounts for about 76% of the Index of Industrial Production (IIP), grew 9%, while electricity and gas supply rose 12.3%. Mining and quarrying moved in the opposite direction, contracting 5.6%. The result is a stronger industrial economy on the face of it, but the composition of that growth is more revealing than the headline number.
The IIP is a measure of changes in the volume of industrial production, not a scorecard for the entire economy. Because manufacturing carries such a large weight, a sharp rise in factory output can lift the index even when other parts of industry are under pressure. The August data show that clearly: capital goods and intermediate goods recorded double-digit growth, while mining contracted and consumer non-durables rose only 2.1%. The question is therefore less whether industrial activity is recovering than how broad and durable the recovery will prove to be once the favourable year-earlier comparison fades.

The numbers suggest that industrial activity has gained momentum. They also show why the 8% headline needs to be read with some care. Manufacturing carries about 76% of the weight in the new IIP, while mining accounts for about 11%. A strong manufacturing performance can therefore more than offset a sharp contraction in mining. The index tells us that production has increased; it does not by itself tell us whether demand, investment, profits or employment have strengthened to the same extent.
India’s industrial growth: What the IIP actually measures
The IIP measures changes in the volume of production relative to the base period. It is therefore different from a measure based on the rupee value of goods produced. A rise in the value of output can reflect higher prices, whereas an increase in the IIP is intended to capture changes in production volumes.
The revised series, with 2022-23 as the base year, has broadened the coverage of industrial activity and changed the basket and weights. MoSPI says the new series covers 463 item groups and adds 120 new groups, while bringing minor minerals, rare earth minerals, gas supply, water supply, sewerage and waste management into the framework.
The weighting of the index is important when interpreting the August data. Manufacturing accounts for 76.062% of the new IIP, compared with 11.053% for mining and quarrying, 10.865% for electricity and gas supply and 2.020% for water supply, sewerage and waste management.
A 1% movement in manufacturing consequently has a much larger effect on the headline index than a similar movement in mining. An 8% rise in industrial production does not mean that Indian industry as a whole expanded by 8%. It represents the weighted outcome of sectors and industries with very different performances.
Nor should the IIP be read as a measure of industrial profitability. A factory can increase physical output while facing higher input costs and lower margins. Conversely, production can fall temporarily because inventories are high even when underlying demand remains firm. The IIP is best read alongside prices, credit, exports, consumption and investment data.

Manufacturing is strong, but the recovery is uneven
Manufacturing was the main source of August’s strength. Eighteen of the 23 manufacturing industry groups recorded year-on-year growth. Electrical equipment output rose 30.9%, other transport equipment 25.3% and motor vehicles, trailers and semi-trailers 25.2%. Computers and electronic products, rubber and plastics and several other manufacturing segments also recorded strong growth.
This is a substantial improvement in industrial activity, but manufacturing cannot be treated as a homogeneous sector. Five of the 23 groups contracted in August, including tobacco, apparel, refined petroleum products, chemicals and paper. Strong output of automobiles and electrical equipment can coexist with weakness in labour-intensive industries such as apparel.
The comparison with August 2025 also requires caution. Year-on-year IIP growth can be lifted by a favourable base when production in the corresponding month a year earlier was unusually weak. ICRA’s Rahul Agrawal attributed part of the favourable base in August to inventory recalibration in the year-earlier month ahead of the implementation of GST rate cuts.
There was also a sequential decline in production. Manufacturing output fell 1.4% from July, while overall industrial production declined 1.8%. The year-on-year rate is therefore telling a stronger story than the month-to-month movement. That does not invalidate the August result, but it does argue against treating one month’s growth rate as evidence of a sudden change in the underlying pace of industrial activity.
Capital goods point to investment, but do not prove a boom
The use-based classification provides another way to examine the August numbers. Capital goods output rose 16.9%, intermediate goods 13.7%, consumer durables 11.1%, infrastructure and construction goods 6.4%, and primary goods 3.5%. Consumer non-durables grew only 2.1%.

The strength in capital and intermediate goods is significant because these categories include machinery, equipment, components and other inputs used in production. Their expansion is consistent with stronger investment activity. But IIP data alone cannot establish that private investment has entered a sustained expansion. That requires evidence from capacity utilisation, corporate investment, bank credit, new project announcements and actual capital expenditure.
The contrast with consumer non-durables is also worth watching. These goods include products associated with everyday consumption. Their 2.1% growth in August followed a 0.8% contraction in July, and their output was only 1.2% higher during April-August than a year earlier. Consumer durables, by contrast, grew 11.1% in August.
The distinction does not provide a direct measure of household purchasing power, since production data are also affected by inventories, exports and supply conditions. It does, however, suggest that the recovery in industrial production is stronger in some discretionary and investment-linked categories than in everyday consumer goods.
Mining is another weak spot. Output fell 5.6% year-on-year in August, the sharpest contraction since the launch of the new IIP series. Mining is affected by seasonal factors, including the monsoon, but its weakness remains relevant because the sector supplies raw materials to much of the industrial economy.
The August IIP therefore presents a more complicated picture than the headline suggests. Manufacturing is expanding strongly and investment-linked categories are recording double-digit growth. Electricity and gas supply also rose sharply. At the same time, mining remains weak and the increase in consumer non-durables is modest.
The test now is whether the stronger industrial output survives the favourable base and becomes broader across sectors. The coming months will show whether capital goods and intermediate goods continue to grow at high rates, whether consumption becomes less concentrated in durables, and whether mining recovers. The festive season will provide an important demand test, but the more meaningful evidence will come after the favourable comparisons fade.
The 8% figure is therefore encouraging as a measure of industrial volume growth. Its significance will depend on what follows it.
