Overview
The Index of Core Industries (ICI) has been re‑based to Base Year 2022‑23. The Ministry of Commerce & Industry through the Office of Economic Adviser (OEA) released the June 2026 provisional figures on 20 July 2026.
Key Developments
- Iron ore is added as a new core item, raising the count of core industries from eight to nine.
- Steel index now uses gross production data, aligning it with the Index of Industrial Production (IIP) methodology.
- Only raw coal is retained; coal middling and washed coal are excluded to avoid double counting.
- Weights for the new series are derived from the corresponding IIP weights and scaled to 100.
- The Linking Factor between the old (2011‑12) and new (2022‑23) series is calculated as 1.47.
- Provisional ICI for June 2026 shows a **5.0 %** YoY rise, driven mainly by iron ore (+43.9 %) and electricity (+9.8 %).
Important Facts & Figures
Growth rates (June 2026, provisional):
- Iron Ore: +43.9 %
- Electricity: +9.8 %
- Cement: +9.8 %
- Steel: +4.6 %
- Coal: +1.4 %
- Natural Gas, Crude Oil, Refinery Products, Fertilizers: negative growth.
The cumulative growth for April‑June 2026 is **3.6 %** (provisional), up from **1.0 %** in the same period of the previous year.
Exam Relevance
Understanding the ICI is essential for GS‑3 (Economy) as it reflects the health of core manufacturing sectors, which influence employment, export potential, and fiscal revenue. The shift to a newer Base Year aligns the index with recent structural changes in the economy, a point often asked in data‑interpretation questions. The concept of a Linking Factor is useful for handling series revisions, a typical analytical skill tested in the mains.
Moreover, the inclusion of iron ore underscores the government's focus on resource‑based industries, linking to policy discussions in GS‑2 (Polity) about the role of ministries such as the Ministry of Commerce & Industry in shaping industrial strategy.
Way Forward
- Students should track monthly ICI releases to observe sectoral trends and correlate them with policy announcements.
- Practice converting provisional figures into final estimates to understand data reliability.
- Analyse the impact of the new weightage on sectoral contributions, especially the rise of iron ore, for answer writing in GS‑3.
- Use the linking factor (1.47) to compare historic data with the new series when answering time‑series questions.
Regular monitoring of the ICI will help aspirants develop a nuanced view of India’s industrial trajectory, a key component of the economy syllabus.
