Index of Core Industries: Features, Significance & Challenges

India revised the Index of Core Industries with a 2022–23 base year, improving industrial measurement and policy relevance.

About Index of Core Industries (ICI)

• Meaning: Measures monthly production performance of India’s nine core infrastructure industries, published by the Office of the Economic Adviser.
• Economic Significance: Serves as a lead indicator of industrial growth, carrying 40.27% weight in the Index of Industrial Production (IIP).
• Sector Coverage: Covers Coal, Crude Oil, Natural Gas, Refinery Products, Fertilisers, Steel, Cement, Electricity, and Iron Ore (new addition).

Key Features of New ICI

• Basket Expansion: Adds iron ore and assigns it a 4.905% weight, expanding the core industry basket from eight to nine industries.
• IIP Alignment: Uses gross instead of net production data for the Steel index, and reduces the combined weight of nine core industries to 32.88% to align with the Index of Industrial Production.
• Sectoral Weights: Electricity (30.932%) has the highest weight, followed by refinery products (22.572%).
• Metric Refinement: Only raw coal is retained, excluding by-products such as Coal Middlings and Washed Coal to prevent double-counting.
• Linking Factor: It is the ratio of the old and new series’ monthly geometric means, in line with the IIP 2022-23 methodology.

Significance of the Revised Core Sector Growth Framework

• Accurate Measurement: Revising the base year to 2022–23 better reflects India’s evolving industrial structure, improving the accuracy and relevance of industrial output estimates.
• Evidence-Based Policy: Reliable core sector data guides decisions on industrial policy, infrastructure investment, and energy planning, with core industries contributing 40.27% to the IIP.
• Industrial Monitoring: The revised framework captures real-time industrial trends, as reflected in 5% core sector growth in June 2026, the highest in five months.
• Infrastructure Planning: Inclusion of iron ore strengthens tracking of PM Gati Shakti, NIP, and Make in India-driven infrastructure expansion and steel-led industrial growth.

Challenges of the Revised Core Sector Growth Framework

• Energy Weakness: Crude oil output declined for the 18^th consecutive month, while natural gas contracted for the 24^th month, highlighting persistent energy security concerns.
• Base Effect: June 2026 core sector growth reached 5%, with iron ore output surging 43.9%, partly reflecting a low-base effect rather than broad-based expansion.
• Data Reliability: Frequent revisions (May 2026 growth revised from 1% to 3.2%) highlight the need for robust industrial databases and real-time reporting.
• Global Volatility: Falling global crude prices reduced refinery output by 4.7%, while geopolitical disruptions continue affecting energy and commodity supply chains.
• Structural Dependence: India imports nearly 88.5% of its crude oil, making industrial growth vulnerable to external energy shocks despite domestic reforms.

Way Forward

• Regular Revision: Periodically revise base years, following the 2022–23 ICI update, to accurately capture India’s evolving industrial structure.
• Expand Coverage: Include critical minerals, battery materials, and renewable energy equipment supporting Mission Critical Minerals and India’s Net Zero 2070 goals.
• Digital Systems: Leverage AI, GIS, IoT, and API-based reporting enabling real-time industrial monitoring and improving data reliability.
• Mining Reforms: Strengthen mineral exploration under the National Mineral Policy, 2019, with iron ore’s inclusion reflecting mining’s growing industrial significance.
• Integrated Indicators: Harmonise ICI, IIP, GDP, CPI, WPI, PPI, and the Index of Services Production, ensuring consistent, evidence-based macroeconomic policymaking.

“What gets measured gets managed.” A robust, dynamic ICI enables evidence-based policymaking, industrial resilience, and sustainable economic growth.
