India’s industrial sector showed mixed performance in October 2025, with Mining contracting by 1.8%, Manufacturing expanding by 1.8%, and Electricity output declining sharply by 6.9%.
The fall in electricity generation was attributed to extended rainfall and comfortable temperatures across several States and UTs, which dampened overall demand. The overall IIP for October stood at 150.9, slightly higher than 150.3 in October 2024, with sectoral indices at 126.2 for Mining, 151.1 for Manufacturing, and 193.4 for Electricity.
