India’s Core Sector Growth Hits Series High of 7.9% in September 2026

India’s core sector output grew 7.9 per cent year-on-year (YoY) in September 2026, recording its fastest growth under the current data series. The expansion was supported by higher production of iron ore, electricity, coal and refinery products. Growth accelerated from 5.9 per cent in August 2026 and 3.1 per cent in September 2025, according to data released by the Ministry of Commerce & Industry on October 21, 2026. The improvement comes as infrastructure activity and industrial production remain important indicators of domestic economic demand.

The Index of Core Industries (ICI), which tracks nine key infrastructure industries, recorded its highest growth since the current data series began in April 2024. The index’s base year has been updated to FY23. Six industries reported positive year-on-year growth in September, while crude oil, natural gas and fertilizers continued to contract. The government also revised August’s core sector growth estimate upward to 5.9 per cent from the provisional estimate of 4.8 per cent, indicating stronger industrial activity than initially assessed. Cumulatively, core sector growth stood at 5.1 per cent during April-September 2026, compared with 2.5 per cent during the corresponding period last year.

Iron ore production recorded the strongest growth among the core industries, increasing 18.4 per cent year-on-year in September, compared with 5.5 per cent in August. Coal production recovered significantly, rising 10.7 per cent after declining 3.8 per cent in the previous month. Refinery products output increased 10.3 per cent, compared with 5.6 per cent in August. Electricity generation maintained double-digit growth at 11.4 per cent, although it moderated from 13.1 per cent in the previous month.

Cement production increased 9.8 per cent year-on-year in September, compared with 11.7 per cent in August, while steel production grew 4.9 per cent following a 3.5 per cent increase in the previous month. The growth in cement and steel output indicates continued activity in Construction and infrastructure-related industries. Demand from road development, housing and other capital-intensive projects remains important for these sectors. However, the moderation in cement production growth highlights that the improvement was not uniform across industries.

Despite the broader improvement, weaknesses persisted in some segments. Fertilizer production contracted 11.7 per cent year-on-year in September, marking its seventh consecutive month of decline. Natural gas production fell 4.6 per cent, while crude oil output declined 1.4 per cent. These contractions highlight continuing challenges in domestic energy production and fertilizer manufacturing, limiting the breadth of the overall industrial recovery.

The stronger core sector data could provide a positive operating signal for companies exposed to mining, electricity, refining, cement and steel. Listed companies such as Coal India Ltd, NTPC Ltd, UltraTech Cement Ltd and Steel Authority of India Ltd operate in industries represented in the index. However, the government’s data reflect industry-wide production trends and do not establish the performance of individual companies or confirm that their share prices gained following the announcement. Higher production can support business volumes, but company earnings also depend on selling prices, input costs, demand conditions and company-specific operating factors.

The 7.9 per cent expansion in September points to improving industrial momentum, supported by stronger output across several key industries. However, the continued contraction in crude oil, natural gas and fertilizers indicates that the recovery remains uneven. The upcoming Index of Industrial Production (IIP) data will provide a broader assesSMEnt of manufacturing and industrial performance. Sustained growth in infrastructure-related industries, accompanied by a recovery in energy production and fertilizers, would indicate a more balanced expansion of India’s industrial economy.
