The April reading is the first estimate under the revised series, which aims to better reflect the evolving structure of India's industrial economy, emerging manufacturing segments and newer infrastructure-related activities. "India's industrial cycle started FY27 on a firm footing, with the new base IIP up 4.9% YoY in April 2026, led by a 6.2% expansion in manufacturing. Mining's 5.1% contraction weighed on the headline, but the breadth of manufacturing, with 17 of 23 industry groups recording a positive growth, helped offset the drag..." said Rajeev Sharan, head of research, Brickwork Ratings. Industrial production in March under the old series had expanded by 5.2%.
