RBI Tightens Bank Liquidity Requirements

The Reserve Bank of India (RBI) has tightened bank liquidity requirements by increasing the minimum daily Cash Reserve Ratio (CRR) maintenance from 90% to 99%, effective 16 October, 2026. However, the overall CRR remains unchanged at 3%. The move aims to improve liquidity management and bring short-term borrowing rates closer to the RBI’s repo rate.

RBI Tightens Bank Liquidity Requirements

The decision comes as the banking system continues to hold surplus funds. The RBI has also raised the repo rate to 5.50% and announced an open market sale of government securities worth ₹25,000 crore to absorb excess liquidity. These measures could affect banks’ funding costs, deposit mobilisation and lending activities.

RBI Tightens Bank Liquidity Requirements: Key Highlights

What Has Changed in RBI’s CRR Rules?

The RBI has increased the minimum amount of the prescribed CRR that banks must maintain every day. Previously, banks had to maintain at least 90% of their required CRR daily. From October 16, 2026, this minimum will increase to 99%. The overall CRR remains at 3%. This means the RBI has not increased the reserve ratio itself; it has made the daily maintenance requirement stricter.

Under the new rule, banks will have less flexibility to manage their cash reserves throughout the reporting fortnight. They will need to keep their daily balances closer to the prescribed requirement.

What Is the Cash Reserve Ratio (CRR)?

The Cash Reserve Ratio (CRR) is the percentage of a bank’s specified deposit liabilities that it must keep as cash with the RBI. Banks cannot use these funds for regular lending or investment activities. The CRR helps the RBI manage the amount of money available in the banking system.

Example: If a bank has ₹10,000 crore in eligible deposits and the applicable CRR is 3%, it must maintain ₹300 crore with the RBI.

Why Has the RBI Tightened Bank Liquidity Requirements?

The RBI’s decision is linked to surplus liquidity in the banking system and its efforts to keep short-term interest rates closer to the policy repo rate.

• To Manage Excess Liquidity : The banking system received substantial foreign-currency deposit inflows through the RBI’s FCNR(B) deposit scheme. According to the reported figures, banks mobilised approximately $127 billion under the scheme before it closed on August 31, 2026. The banking system’s liquidity surplus rose to more than ₹10 lakh crore in early September. Although it later declined, surplus funds remained significant. The RBI has used measures such as reverse repo operations, foreign exchange swaps and government securities sales to manage this surplus.
• To Bring Short-Term Rates Closer to the Repo Rate : The repo rate is an important policy rate used by the RBI to influence borrowing costs and monetary conditions. The weighted average call rate (WACR), which reflects overnight interbank borrowing costs, was reported at 5.31% on October 9, 2026, below the repo rate of 5.50%. By increasing daily CRR maintenance, the RBI aims to improve liquidity management and bring overnight borrowing rates closer to its policy rate.
• To Support Monetary Policy Measures : The RBI recently raised the repo rate by 25 basis points to 5.50% to address inflationary pressures. The stricter daily CRR requirement supports its broader liquidity-management approach. However, it is important to remember that the daily maintenance rule has changed while the overall CRR remains at 3%.

RBI’s Recent Liquidity Measures

The RBI is using different measures to manage liquidity and influence short-term borrowing conditions.

How Will the New CRR Rule Affect Banks?

The impact will depend on each bank’s deposits, loan growth and funding requirements.

• Less Flexibility in Cash Management : Banks will have less freedom to maintain lower CRR balances on certain days. They will need to plan their daily cash requirements more carefully.
• Possible Increase in Short-Term Borrowing Costs : Banks facing temporary cash shortages may need to borrow funds to meet their requirements. If liquidity becomes tighter, short-term borrowing costs could rise.
• Greater Need to Attract Deposits : Banks need deposits to support their lending activities. If loans grow faster than deposits, they may face greater pressure to attract new deposits or arrange alternative funding.
• Different Impact on Different Banks : Banks with strong deposit growth may be better placed to support credit expansion, while banks whose loans grow faster than deposits may face greater funding pressure.

What Does the RBI’s Decision Mean for NBFCs?

Non-Banking Financial Companies (NBFCs) may also be affected because many depend on banks and other financial institutions for funding. If banks face higher funding costs or become more cautious about lending, some NBFCs could find borrowing more expensive or difficult. The possible effects include:

• Higher borrowing costs: NBFCs may have to pay more for funds.
• Pressure on profit margins: Higher funding costs can reduce margins if lending rates do not adjust quickly.
• Tighter access to credit: Some NBFCs may find it harder to obtain funds from banks.
• Greater need for alternative funding: NBFCs may look for additional sources of finance to reduce their dependence on bank borrowing.

Will Loan Interest Rates and EMIs Increase?

The revised CRR maintenance rule does not automatically increase loan interest rates or EMIs. However, if banks face higher funding costs because of tighter liquidity, they may reconsider their lending rates depending on market conditions, their funding sources and applicable loan benchmarks.

Borrowers should distinguish between the repo rate and the CRR rule. The repo rate influences monetary policy and borrowing costs, while the CRR requirement determines how banks maintain their reserves with the RBI. Any change in a borrower’s EMI will depend on the terms of the loan and whether the applicable interest rate changes.

What Should Banks Watch Next?

• Banks and market participants will closely monitor liquidity conditions, deposit growth, short-term borrowing rates and credit demand following the implementation of the new rule.
• Banks with faster loan growth will need to maintain a healthy balance between lending and deposit mobilisation. NBFCs will also need to monitor their funding costs and access to bank credit. The RBI’s next steps will depend on how liquidity conditions evolve and whether short-term market rates move closer to the policy repo rate.
