The RBI CRR Rules change will require banks to maintain at least 99% of their prescribed Cash Reserve Ratio (CRR) on a daily basis from October 16, 2026, up from the existing minimum of 90%.
The Reserve Bank of India (RBI) has announced the revision to reduce excess liquidity in the banking system and tighten daily cash management by banks.
The overall CRR requirement remains unchanged at 3% of a bank’s net demand and time liabilities.Â
The change concerns the minimum amount banks must maintain each day, reducing their flexibility to compensate for lower balances on some days by holding more reserves on others.
 RBI CRR Rules: What Changes From October 16
Under the revised requirement, scheduled banks must maintain at least 99% of the prescribed CRR on every day during the reporting fortnight, beginning October 16, 2026.
Previously, banks were permitted to maintain at least 90% of the required amount daily, provided their average balance over the fortnight met the full prescribed requirement.
The new rule significantly reduces this operational flexibility.
Banks will need to manage their daily cash positions more carefully to ensure they meet the minimum reserve requirement while continuing to handle withdrawals, payments and other financial obligations.
The RBI’s decision follows a review of liquidity conditions in the banking system.
The central bank has been working to absorb surplus funds through multiple measures, including variable rate reverse repo auctions and open market operations.
 What Is CRR and Why Does It Matter?
The Cash Reserve Ratio is the share of specified bank liabilities that scheduled banks must maintain as cash balances with the RBI.
These balances do not earn interest, and the funds kept as CRR cannot be used by banks for lending or other commercial purposes.
With the overall CRR remaining at 3%, a bank must maintain Rs 3 with the RBI for every Rs 100 of applicable liabilities, subject to the regulatory calculation.
The revised rule does not increase this percentage; instead, it raises the minimum daily maintenance requirement from 90% to 99% of the prescribed amount.
For example, if a bank’s calculated CRR requirement is Rs 100 crore, the minimum daily balance under the earlier rule could be Rs 90 crore.
From October 16, the minimum will rise to Rs 99 crore, while the bank must still satisfy the full prescribed requirement on average over the reporting fortnight.
 Why the RBI Is Tightening Daily Cash Requirements
The move comes as the RBI seeks to absorb excess liquidity from the banking system.
The surplus had declined to around Rs 3.88 lakh crore as of October 8, 2026, following earlier liquidity-management operations.
When banks have substantial surplus funds, short-term money market interest rates can remain below the RBI’s policy repo rate.
Tighter daily reserve requirements can reduce the cash available for other uses and may help bring overnight market rates closer to the policy rate.
The RBI has also announced an open market operation involving the sale of government securities worth Rs 25,000 crore on October 13, 2026.
Such sales absorb rupee liquidity from the banking system as buyers pay for the securities.
Will the New RBI CRR Rules Affect Customers?
The immediate change applies to banks’ reserve management, not directly to the CRR percentage charged to customers.
However, tighter liquidity conditions can influence banks’ short-term funding costs and money market interest rates.
If banks face higher funding costs, the effect on lending rates, deposit rates and other banking products will depend on market conditions, competition and each bank’s funding position.
The revised daily maintenance rule does not automatically mean that every bank will increase loan interest rates or reduce deposit returns.
Customers should therefore distinguish between a change in reserve maintenance rules and a direct change in the interest rate on their loans or deposits.
Any adjustment to a specific banking product will depend on the bank’s own decisions and the terms of that product.
For banks, the main operational task is to maintain a higher proportion of the prescribed CRR every day while meeting the full fortnightly average requirement.
The revised RBI CRR Rules take effect from the fortnight beginning October 16, 2026, as the central bank continues managing surplus liquidity.
