India's core infrastructure sectors recorded a growth of just 0.5% in May 2026, marking the slowest expansion in seven months, primarily due to a decline in the production of coal, crude oil and refinery products.
According to government data released on Monday, core sector growth moderated from 1.8% in April 2026 and 1.2% in May 2025.
Among the eight core industries, coal, crude oil, natural gas, refinery products and fertilisers registered negative growth during the month, weighing on overall performance. The slowdown reflects continued challenges in key energy-related sectors, which form a significant part of the country's industrial output.
The eight core industries comprise coal, crude oil, natural gas, refinery products, fertilisers, steel, cement and electricity, and collectively account for about 40% of the Index of Industrial Production (IIP).
