India's Index of Core Industries rose 5% in June 2026, but the growth is heavily skewed by the inclusion of volatile iron ore production. Excluding this impact, underlying industrial growth was only 2.85%, raising concerns about the true pace of domestic activity.
Detailed Coverage
The latest data for India’s Index of Core Industries (ICI) shows a 5% year-on-year increase for June 2026. While the headline number appears to be a strong rebound, a closer look at the data shows that this growth is largely supported by specific statistical changes and base effects rather than a broad-based recovery in industrial activity.
Impact of Iron Ore Inclusion
The primary reason for the 5% headline growth is the recent inclusion of iron ore into the index, which now carries a weight of 4.9%. In June 2026, iron ore production saw a significant year-on-year jump of 43.9%. This single sector contributed approximately 2.15 percentage points to the total index growth. When iron ore is removed from the calculation, the growth rate of the core industries drops to 2.85%, reflecting a much more modest performance.
Statistical Illusions and Sequential Trends
Beyond the headline figure, the data shows signs of weakness when looking at month-on-month performance. The index dropped from 120.1 in May 2026 to 119.6 in June 2026, indicating a sequential contraction. The surge in iron ore production was also heavily influenced by a favorable base effect, as production levels were unusually low in June 2025. This creates a statistical illusion of high growth that does not necessarily reflect new industrial momentum.
Sectoral Divergence
Performance across the eight core industries remains uneven. The energy sector, including crude oil, natural gas, and refinery products, continues to act as a drag on the overall index. Conversely, the infrastructure and power sectors show stronger resilience. Electricity generation grew by 9.8%, and cement production also posted a 9.8% rise, suggesting sustained activity in construction and power. Meanwhile, steel production grew by 4.6%. The gap between high iron ore input growth and the relatively slower growth in steel output may suggest that raw materials are being stockpiled or exported rather than consumed immediately by domestic manufacturers.
Investor Takeaways
For investors, the key monitorable will be whether demand across the energy and manufacturing sectors catches up to the high-growth segments like electricity and cement. The revised index, which now uses a 2022-23 base year, aims to provide a more accurate picture by including more upstream activities, but the volatility of these new components means investors should focus on the underlying growth ex-volatility to gauge the health of the industrial economy.
