The first tranche of the Reserve Bank of India's 100 basis point Cash Reserve Ratio (CRR) reduction took effect from the reporting fortnight beginning September 6, 2025. Banks are now required to maintain CRR at 3.75% of Net Demand and Time Liabilities (NDTL), down from 4%. Announced as part of the June 2025 Monetary Policy alongside a 50 bps repo rate cut to 5.5%, the CRR cut will be delivered in four equal tranches of 25 bps each on September 6, October 4, November 1, and November 29, 2025, reducing CRR from 4% to 3%. The phased reduction will release approximately ₹2.5 lakh crore of primary liquidity into the banking system by December 2025, supporting credit growth and economic activity.
