India IIP Gets a Major Makeover: What the 2026 Reforms Mean

The new IIP series will be released on June 1, 2026, according to official announcements. MoSPI will maintain a back series for comparison, allowing users to see consistent trends over time.

What This Means for India

These reforms represent a comprehensive effort to modernise India's industrial statistics. The updated framework incorporates changes in technology, sector composition, and economic activity patterns. Expanded coverage and revised methodologies aim to improve the accuracy of industrial output measurement. The revision is part of a broader initiative to strengthen India's economic data systems, including the planned introduction of an Index of Services Production. Simply put, India will finally have a clearer, more honest picture of its industrial health.
