Core Sector Growth at Series High of 7.9% in September

The country’s core sector output grew at its fastest pace under the current data series in September 2026, expanding 7.9% YoY, supported by higher production of iron ore, electricity, coal and refinery products. The growth was faster than August's 5.9% and September 2025's 3.1%, according to data released by the Ministry of Commerce & Industry on October 21.

The uptick comes as infrastructure activity and industrial production remain key barometers of domestic economic demand.

Core Sector Grows at Its Highest Rate in Current Series

The Index of Core Industries (ICI), which represents nine key infrastructure industries, recorded its fastest growth since the current series began from April 2024. The base year of the index has been updated to FY23.

Six industries, however, reported positive YoY growth in September. Crude oil, natural gas and fertilizers continued to contract.

The government also increased its August growth estimate to 5.9% from a provisional 4.8%, showing industrial activity was stronger than first thought.

Growth in the core sector was 5.1% during April-September 2026, compared with 2.5% during the same period last year.

Iron Ore, Coal & Refinery Products Drive September Surge

Iron ore saw the sharpest rise, with output up 18.4% YoY compared with 5.5% in August. Coal output recovered strongly, increasing 10.7% after falling 3.8% in the previous month.

Refinery products were up 10.3%, against 5.6% in August. Electricity generation sustained double-digit growth but at a slower pace of 11.4% from 13.1%.

But the overall improvement did not hide weaknesses in fertilizers and domestic energy production. Fertilizer output contracted for the seventh consecutive month and natural gas production also declined.

Cement & Steel Production Indicates Infrastructure Activity

Cement production rose 9.8% YoY in September, down from 11.7% in August. Steel production increased 4.9% following a 3.5% gain in the previous month.

The ongoing growth in cement and steel output is indicative of activity in the construction and infrastructure-related industries. Demand from roads, housing and other capital-intensive projects continues to be important for these sectors.

But the better performance was uneven across industries, with slower cement growth than in August.

Why Infrastructure Stocks May React to Data

The stronger numbers in the core sector provide a positive operating signal for companies involved in mining, electricity, refining, cement and steel.

Companies listed on the stock exchange like Coal India, NTPC, UltraTech Cement and Steel Authority of India have exposure to these industries.

But government data capture industry-wide production, not individual company performance. It does not prove these stocks gained on the announcement. A direct share-price reaction remains unproven.

Higher production can help sustain volumes of business, but earnings also depend on selling prices, input costs, demand and company-specific operating conditions.

Outlook: Industrial Momentum Builds, but Gaps Persist

The 7.9% growth in September shows a positive trend in industrial activity, driven by a strong base effect and increased output in several key industries.

The next important indicator is the Index of Industrial Production (IIP), which will offer a wider picture of manufacturing and industrial performance.

Sustained growth in infrastructure sectors, particularly alongside a recovery in crude oil, natural gas and fertilizers, would suggest a more balanced expansion of India’s industrial economy.
