NEW DELHI (Reuters) -India’s infrastructure output was unchanged in October from a year earlier, its weakest performance in 14 months, as declines in coal, crude oil and electricity production offset gains in steel and refinery products, government data showed on Thursday.

The index, which tracks activity across eight sectors and makes up 40% of the country's industrial production, grew at a revised 3.3% in September.

India’s infrastructure output contracted 1.5% year-on-year in August 2024.

Excess rainfall impacted mining activity and power demand in October, while steel output decelerated sharply, said Aditi Nayar, an economist at ICRA.

Given the contraction in the mining and electricity segments, the industrial output growth in October is expected to ease to 2.5%-3.5% from 4% in the previous month, she said.

India's industrial output data will be released on November 28.
