India's industrial output slows to 0.4% in Oct from 4.6% in Sept

India's industrial output grew 0.4% year-on-year in October, which is down from revised 4.6% in September 2025. The government noted that the slower pace was primarily due to fewer working days in October, as the month saw multiple festivals including Dussehra, Diwali, and Chhath.

The IIP is prepared using data submitted by source agencies, which collect production figures from factories and establishments nationwide. The Quick Estimates are provisional and may be revised in subsequent releases in line with the IIP revision framework.

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.
