What Happened
- India's eight core infrastructure sectors recorded a combined growth rate of 4% in January 2026, easing from a revised 4.7% in December 2025 and 5.1% in January 2025
- The slowdown was primarily driven by contractions in crude oil production (down 5.8% YoY) and natural gas production (down 5% YoY), both of which have been on a declining trend due to ageing domestic fields and limited new discoveries
- Cement output remained the standout performer with 10.7% growth in January, while steel output grew a robust 9.9%, reflecting continued momentum in construction and infrastructure activity
- Electricity generation growth moderated from its December pace, while refinery products and fertiliser output posted modest gains
- For the first 10 months of FY26 (April–January), core sector cumulative growth stands at a modest 2.8%, compared to 4.5% in the same period of FY25 — a significant deceleration

Eight Core Industries — Composition, Weightage, and Significance
The Index of Eight Core Industries (ICI) is a monthly output index tracking the performance of eight infrastructure-linked industries that are considered the backbone of industrial production in India. These industries account for 40.27% of the weight of items included in the Index of Industrial Production (IIP), making core sector performance a leading indicator of overall industrial activity. The index is compiled by the Office of the Economic Adviser (OEA), Ministry of Commerce and Industry, and released about six weeks after the reference month, with two revisions thereafter.
- The eight industries: Coal, Crude Oil, Natural Gas, Refinery Products, Fertilisers, Steel, Cement, Electricity
- Combined weight in IIP: 40.27%
- Release agency: Office of the Economic Adviser, Ministry of Commerce and Industry
- IIP itself is compiled by the National Statistics Office (NSO), MoSPI; base year is 2011-12 (under revision to 2022-23)
- Cement (weight: 5.37%) and Steel (weight: 17.92%) together account for the largest share; their strong performance partially cushioned the January 2026 decline
- Crude oil and natural gas together account for ~15% weight but are both in structural decline
Connection to this news: The January 2026 data illustrates a structural bifurcation in India's core sector: construction-linked industries (cement, steel) are booming driven by government infrastructure spending, while energy production industries (crude oil, natural gas) are in secular decline, creating a drag on the overall index.
Index of Industrial Production (IIP) — Structure and Economic Significance
The Index of Industrial Production (IIP) is India's primary measure of short-term industrial output, compiled monthly by the National Statistics Office (NSO). It covers manufacturing (77.63% weight), mining (14.37%), and electricity (7.99%). Because core sector data is released before IIP data (due to the 6-week lag), the core sector index serves as an advance signal for IIP trends. A slowdown in core sector growth — as seen in January 2026 — typically presages softer IIP numbers for the same month.
- IIP base year: 2011–12 (being revised to 2022-23)
- IIP composition by sector: Manufacturing 77.63%, Mining 14.37%, Electricity 7.99%
- IIP composition by use: Capital Goods (most volatile; tracks private investment), Consumer Goods (Consumer Durables + Non-Durables), Infrastructure/Construction Goods, Intermediate Goods
- Published: NSO, six weeks after reference month
- IIP growth was running at ~3-4% in H2 FY26, below the 6–7% seen in FY24
- Core industries collectively represent a bridge between primary resources (mining) and downstream manufacturing
Connection to this news: A 4% core sector growth in January — and only 2.8% for April–January FY26 — signals that India's broader industrial momentum has lost pace compared to the previous year. This has direct implications for IIP numbers and broader GDP growth projections for FY26.
India's Hydrocarbon Sector — Structural Decline and Policy Response
India's crude oil and natural gas production has been in a prolonged decline due to ageing major fields (Mumbai High, Bassein, Ravva), limited new discoveries, and insufficient investment in upstream exploration. India imports ~88% of its crude oil requirements, making it the world's third-largest oil importer. The government has attempted to reverse the production decline through the HELP (Hydrocarbon Exploration and Licensing Policy, 2016), the National Seismic Programme, and strategic partnerships with OPEC+ countries for assured supply.
- India's domestic crude oil production: ~29–30 million tonnes per year (well below peak of ~40 MT in 2010–11)
- Crude oil self-sufficiency: ~12% (domestic production as share of consumption)
- India's crude oil imports: ~235–240 million tonnes per year; top suppliers: Russia (~32%), Iraq (~22%), Saudi Arabia (~17%)
- HELP (2016): replaced NELP (New Exploration Licensing Policy, 1999); introduced revenue-sharing model (replaced profit-sharing), unified licensing, and open acreage policy
- Major upstream companies: ONGC, OIL (Oil India Ltd); major refiner: IOC, HPCL, BPCL
- Natural gas domestic production: ~35 billion cubic metres per year; targets increased through new fields like KG-D6 (Reliance-BP joint venture)
Connection to this news: January 2026's crude oil contraction of 5.8% and natural gas contraction of 5% continue a multi-year trend — not a sudden shock. This structural underperformance in energy production is a persistent drag on India's core sector index and one of the central challenges for India's energy security.
