The Reserve Bank of India has mandated that banks maintain 99% of their Cash Reserve Ratio on a daily basis, up from 90%. This measure aims to soak up excess liquidity in the banking system, which recently reached ₹5.9 lakh crore due to foreign currency inflows. This move may tighten short-term money market rates and influence bank profitability.
The Reserve Bank of India has introduced a stricter rule for how banks manage their daily cash reserves. Starting from the fortnight beginning October 16, 2026, all scheduled banks must maintain at least 99% of their required Cash Reserve Ratio (CRR) on a daily basis. This is an increase from the previous requirement of 90%.
Under the existing rules, banks had a degree of flexibility to balance their reserve obligations over a two-week period, provided they met the 90% threshold daily. The new mandate removes much of this flexibility, requiring banks to be more precise with their daily cash holdings at the central bank.
This regulatory shift is a direct response to a massive surplus of money circulating in the banking system. Systemic liquidity has been hovering around a daily average of ₹5.9 lakh crore, largely driven by significant foreign currency inflows, including FCNR (Foreign Currency Non-Resident) deposits. This excess cash has made it challenging for the central bank to keep short-term interest rates aligned with its policy objectives.
For the broader economy, this change is designed to drain excess money out of the banking system. When banks are forced to park more of their funds at the central bank daily—where these deposits earn zero interest—the amount of available cash for lending or short-term trading is reduced. This helps the RBI ensure that the short-term rates in the money market stay close to the repo rate, which is the interest rate at which the RBI lends to banks.
This decision follows the Monetary Policy Committee meeting on October 7, 2026, where the RBI hiked the repo rate by 25 basis points to 5.50% and adopted a stance of calibrated tightening. By combining this interest rate hike with stricter reserve requirements, the central bank is aiming to control inflation and manage the overall cost of money in the economy.
For bank investors, the primary monitorable is how this affects net interest margins. Since banks will now have less operational flexibility and must maintain higher daily reserves, the cost of funds may rise slightly for some institutions. If banks find it harder to deploy surplus funds, it may lead to a rise in overnight money market rates. Investors should watch for commentary from banks in the coming weeks regarding the impact on their lending capacity and daily liquidity management costs.
