Production growth in India's nine key infrastructure sectors accelerated to 5.4 per cent in July, supported by higher output in coal, refinery products, cement, electricity and iron ore, according to official data released on Thursday.
The performance marks a significant improvement over the 3.2 per cent growth recorded by the core sectors in July 2025, although the pace was slower than the 6 per cent expansion registered in June 2026. The nine sectors together form a crucial component of industrial activity and account for a substantial share of the Index of Industrial Production (IIP).
The latest data also reflects an important change in the way core sector growth is measured. Since June, the government has been releasing the index with a revised base year of 2022-23, replacing the earlier base year of 2011-12. The revision is aimed at providing a more contemporary representation of changes in the structure and composition of the Indian economy.
As part of the revision, iron ore has been added to the core sector index, taking the total number of key infrastructure sectors from eight to nine. The inclusion is expected to provide a broader picture of activity in the mining and industrial segments, particularly given the importance of iron ore to India's steel and manufacturing industries.
The nine core sectors now comprise coal, crude oil, natural gas, refinery products, fertilisers, steel, cement, electricity and iron ore. Their combined performance is closely watched because these industries provide critical inputs to manufacturing, construction, transportation and other parts of the economy.
The rise in July output indicates continued momentum in several energy and industrial segments. Higher coal production, for instance, points to stronger activity in the energy sector, while increased refinery output reflects demand and operational trends in the petroleum industry. Growth in cement production is closely linked to construction and infrastructure activity, while electricity generation provides an important indicator of overall economic and industrial demand.
Iron ore output has also gained greater importance in the revised index following its inclusion. The sector's performance is closely connected to steel production and infrastructure development, making it a significant indicator of industrial activity.

The core sector data is particularly important because the nine industries collectively have a major influence on the overall IIP. A sustained improvement in their output can therefore support industrial production figures in the coming months, although the impact on the headline IIP will also depend on the performance of other manufacturing and mining segments.
The July numbers come against the backdrop of continued government emphasis on infrastructure development and capital expenditure. Higher activity in sectors such as cement, electricity, coal and iron ore could provide support to construction, manufacturing and investment-related activity.
However, the moderation from June's 6 per cent growth suggests that the recovery is not uniform across all core industries. The month-on-month movement will need to be assessed alongside sector-specific trends and broader domestic demand conditions.
With the revised base year and expanded coverage now in place, the core sector index is expected to offer a more updated measure of infrastructure and industrial activity. The July performance, marked by a 5.4 per cent expansion, points to healthy growth across several critical sectors while also highlighting the need to monitor the pace of expansion in the months ahead.
