Why in news?
India’s Index of Industrial Production grew 6.7 per cent during July 2026. Manufacturing and electricity helped offset a contraction in mining. The general index reached 124.8, compared with 117.0 one year earlier. These are quick estimates under the new base year of 2022–23.
The July numbers
The National Statistics Office released the data on 28 August. Manufacturing output rose 7.3 per cent from July 2025. Electricity and gas supply grew 8.7 per cent. Mining and quarrying fell by 0.9 per cent.
Water supply, sewerage and waste management grew 7.4 per cent. This sector appears separately in the revised series. The four sectoral indices stood at 94.4, 127.4, 133.5 and 148.4. The general index combined them using fixed weights.
Nineteen of 23 manufacturing groups recorded annual growth. Motor vehicles, trailers and semi-trailers made the largest positive contribution. Electrical equipment and other machinery also contributed strongly. A contribution depends on both growth and the group’s weight.
What the index measures
The Index of Industrial Production is commonly called IIP. It measures changes in the physical volume of selected industrial output. The index covers mining, manufacturing, electricity and selected utility activities. It does not cover services or the entire economy.
The base-year average is set at 100. An index of 124.8 means measured output is 24.8 per cent above that base level. It does not mean output grew 24.8 per cent during July. Annual growth compares July 2026 with July 2025.
The National Statistics Office compiles information from government and industry source agencies. Those agencies collect production data from factories and establishments. The first release is called a quick estimate. Later information can revise the result.
The 2022–23 base revision
India introduced the new IIP series during June 2026. It replaced the older 2011–12 base year. A newer base reflects changes in products, technology and industrial structure. It also updates factories, data sources and weights.
The revised basket contains newer products and removes outdated items. It uses the National Industrial Classification for consistent grouping. Broader electronic reporting supports faster compilation. Method changes can affect comparisons with the old series.
Users should compare like with like. Growth rates in the release use a back-series prepared on the new basis. A level from the old series should not be directly matched with 124.8. Proper metadata are essential for long-term analysis.
Use-based reading of demand
IIP also groups products by their broad economic use. Capital goods grew 16.1 per cent during July. Intermediate goods rose 10.0 per cent. Infrastructure and construction goods grew 6.9 per cent.
Consumer durables increased 10.5 per cent. Consumer non-durables fell 1.0 per cent. Primary goods grew 4.1 per cent. Intermediate, capital and primary goods made the largest positive contributions to overall growth.
Capital-goods growth can indicate stronger equipment production. It does not automatically prove a completed investment boom. Intermediate goods feed later production stages. Consumer non-durables may reflect everyday demand, but their basket is selective.
How to interpret the result
The 6.7 per cent increase shows broad industrial improvement over the previous July. Manufacturing strength is encouraging because it carries substantial weight. Mining weakness shows that progress was uneven. One month cannot establish a lasting trend.
Weather, working days and base effects can move monthly growth. Sector-specific orders and inventory changes also matter. Analysts should compare several months and other indicators. Useful companions include purchasing surveys, company results, freight and credit data.
IIP and gross domestic product answer different questions. IIP focuses mainly on production volume in selected industries. Gross value added also considers the value created after intermediate inputs. Services and agriculture lie outside IIP.
Why revisions matter
The release arrives twenty-eight days after the reference month. Speed makes the estimate useful for current decisions. Some factories or agencies may later provide revised information. The published revision policy allows the series to incorporate it.
Users should label every figure as quick, revised or final. Policy statements should avoid false precision from one early estimate. Revisions do not automatically indicate an error. They reflect the trade-off between speed and completeness.
Level and growth are different
The index level was 124.8, while annual growth was 6.7 per cent. The first compares with the base year; the second compares with July 2025.
Conclusion
July’s IIP release points to strong manufacturing and utility production. Mining and consumer non-durables remained weaker parts of the picture. The new base improves relevance but requires careful historical comparison. Quick estimates should be read with later revisions and other indicators. Sustained industrial strength must appear across months, sectors and final data.
