Overview
The Union Government has released a revised series of the ICI. The new series aligns the ICI with other refreshed macro‑economic metrics such as GDP and GVA. It also brings the ICI on par with the IIP. The changes aim to make the index more current and comparable.
Key Developments
- Base year shifted from 2011‑12 to 2022‑23, reflecting recent industrial structure.
- Number of sectors increased from eight to nine with the addition of the iron ore sector.
- Steel output now measured on a gross‑output basis to match the methodology of the IIP.
- Coal index now records only raw coal, removing middling and washed coal.
- Sectoral weights realigned to mirror those in the IIP, causing significant redistribution.
Important Facts & Weight Changes
The addition of iron ore carries a weight of 4.905%. Consequently, other sectors lose share. Notable downward revisions:
- Coal weight falls from 10.33% to 5.596%.
- Natural gas drops from 6.88% to 3.841%.
- Refinery products reduce from 28.04% to 22.572%.
Upward revisions include:
- Electricity rises sharply to 30.932% from 19.85%.
- Fertilizers increase slightly to 2.731% from 2.63%.
