New IIP series: April industrial growth rises to 4.9% from 3.2% in March

📌 Summary:

• India's industrial output grew 4.9% in April 2026, up from 3.2% in March, as per the new Index of Industrial Production (IIP) series released by MoSPI on Monday
• New IIP series uses 2022-23 as the base year (replacing the older 2011-12 base) and updates methodology and coverage of the indicator
• Past three years' growth revised upward: 2023-24 at 6.7% (vs 5.9% old), 2024-25 at 6.4% (vs 4.0% old), 2025-26 at 4.3% (vs 4.1% old)
• Higher revised growth primarily driven by upward revisions in manufacturing and electricity sub-sectors
• The new base year aligns IIP with the new GDP series and reflects the changed industrial structure (post-Atmanirbhar Bharat / PLI manufacturing expansion)
• Re-basing follows the international statistical convention of revising base year every ~5 years to keep the index representative
