The Reserve Bank of India (RBI) has raised the minimum daily Cash Reserve Ratio (CRR) maintenance requirement for banks to 99% of the prescribed reserve amount from the earlier 90%, effective October 16, 2026. The decision reduces the flexibility banks previously had to manage their reserve balances during a reporting fortnight and forms part of the central bank’s efforts to absorb surplus liquidity from the banking system.

The move does not mean that banks must keep 99% of their total deposits with the RBI. The CRR itself remains a separate percentage of banks’ net demand and time liabilities (NDTL). What changes is the minimum proportion of that required reserve that banks must maintain each day. The RBI has also announced a ₹25,000-crore government bond sale through open market operations, reinforcing its effort to withdraw excess funds from the financial system. Source: Reuters.
What Has the RBI Changed in the CRR Rules?
Under the earlier framework, banks were required to maintain at least 90% of their prescribed CRR on each day of the reporting fortnight, while ensuring that their average daily balance over the period met the full requirement.
From October 16, the minimum daily maintenance threshold will increase to 99%. This leaves banks with much less room to hold lower reserve balances on certain days and compensate with higher balances on others.
| CRR requirement | Earlier rule | New rule from October 16, 2026 |
|---|---|---|
| Minimum daily maintenance | 90% of required CRR | 99% of required CRR |
| Average requirement over the reporting fortnight | 100% | 100% |
| Operational flexibility | Greater | Significantly reduced |
| Main objective | Maintain prescribed reserve levels | Tighten daily reserve discipline and manage liquidity |

The change is primarily an operational tightening. Banks will need to plan their treasury positions more carefully because they will have less scope to allow reserve balances to fall below the full prescribed amount on particular days.
Bankers quoted by The Economic Times said the new rule would reduce operational flexibility, although it was not expected to cause a major structural change in banking operations by itself.
What Is the Cash Reserve Ratio?
The Cash Reserve Ratio is the share of a bank’s net demand and time liabilities that it must maintain as cash balances with the RBI. These liabilities broadly include deposits and certain other obligations.
The RBI uses the CRR as one of its monetary and liquidity-management tools. Money maintained as CRR cannot be deployed by banks for ordinary lending or investment activities, and it does not earn interest for the bank.
For example, consider a simplified bank with ₹1,000 crore in NDTL and an assumed CRR rate of 3%.
| Calculation | Amount |
|---|---|
| Bank’s NDTL | ₹1,000 crore |
| Prescribed CRR at 3% | ₹30 crore |
| Minimum daily balance under the old 90% threshold | ₹27 crore |
| Minimum daily balance under the new 99% threshold | ₹29.7 crore |
| Difference in minimum daily maintenance | ₹2.7 crore |
Illustration only. Actual requirements depend on each bank’s eligible liabilities and applicable RBI rules.
In this example, the bank must maintain at least ₹29.7 crore each day under the new threshold, compared with ₹27 crore previously. The bank must still meet the full ₹30-crore average requirement over the reporting fortnight.
The distinction is important: the RBI has increased the minimum daily maintenance percentage, not raised the underlying CRR rate to 99%.
Why Is the RBI Tightening Liquidity?
The decision comes at a time when India’s banking system has been operating with a substantial surplus of liquidity.
According to The Economic Times, the banking system’s liquidity surplus was around ₹4 lakh crore when the new requirement was announced. Reuters separately reported that surplus liquidity had averaged more than ₹7 lakh crore a day from September 1, equivalent to approximately 2.6% of deposits. These figures refer to different reported measures and periods, but both indicate that surplus funds have been substantial.
Excess liquidity can help banks meet funding requirements and support lending. However, when the RBI wants to tighten financial conditions, it can withdraw surplus funds through reserve requirements and open market operations.
The central bank’s October actions followed a 25-basis-point increase in its Bank Rate, announced earlier in the week, and a broader shift towards more calibrated monetary tightening.
By requiring banks to maintain a larger share of their prescribed CRR every day, the RBI is reducing their ability to manage reserve balances flexibly. Combined with bond sales, the change can contribute to tighter liquidity conditions across the financial system.
RBI Announces ₹25,000-Crore Bond Sale
Alongside the CRR change, the RBI announced that it would sell government securities worth ₹25,000 crore through open market operations on October 13, 2026.
When the RBI sells government bonds to banks and other investors, buyers pay for those securities, transferring funds out of the banking system. This reduces available rupee liquidity, all else being equal.
The planned sale follows a ₹1 lakh-crore net bond sale during September, which Reuters described as the largest net sale in more than a decade.
| Liquidity-management measure | Reported details |
|---|---|
| Daily CRR maintenance | Increased from 90% to 99% |
| Effective date | October 16, 2026 |
| Planned bond sale | ₹25,000 crore |
| Bond-sale date | October 13, 2026 |
| Reported banking-system liquidity surplus | Around ₹4 lakh crore in the Economic Times report |
Sources: Reuters and The Economic Times, October 9, 2026.
The two measures operate through different mechanisms. The CRR change reduces banks’ daily flexibility in maintaining required reserves, while bond sales withdraw liquidity as investors pay for government securities.
Together, they indicate that the RBI is actively managing the banking system’s surplus cash rather than relying only on changes to policy rates.
What Does the New CRR Rule Mean for Banks?
The immediate impact will be on bank treasury operations and liquidity planning.
Banks will need to maintain reserve balances closer to the full prescribed requirement on a daily basis. This could make intraday cash management, payment flows and forecasting of deposit movements more important, particularly for institutions that regularly operate with tighter liquidity buffers.
The new rule does not directly change the CRR percentage itself, so it should not be interpreted as an across-the-board increase in the amount of deposits that banks must reserve. Instead, it limits how much of the required amount they can temporarily fall short of on individual days.
The effect will vary by bank. Institutions with ample liquid assets and strong treasury management may find the adjustment relatively straightforward, while banks that rely more heavily on daily liquidity optimisation may need to adjust their operating practices.
The change may also influence short-term money-market conditions if banks become more cautious about lending surplus funds to one another. The size of that effect will depend on overall liquidity, credit demand and other RBI operations.
Could Loan and Deposit Interest Rates Change?
The new daily CRR rule does not automatically require banks to increase lending rates or reduce deposit rates. Its direct effect is on reserve maintenance rather than the price of credit.
However, tighter banking-system liquidity can influence short-term funding costs. If banks find it more expensive to obtain funds or face stronger competition for deposits, lending rates could come under upward pressure. Banks may also reassess deposit pricing if they need to attract additional funds.
The actual effect on home loans, personal loans, business credit and fixed deposits will depend on several factors, including the RBI’s policy-rate decisions, banks’ funding positions, market interest rates and credit demand.
Borrowers should therefore avoid assuming that their loan interest rates will change immediately because of the new CRR rule. Existing loans linked to external benchmarks are generally affected by changes in the relevant benchmark and the terms of the loan, rather than by a CRR adjustment alone.
What Should Investors Watch Next?
Investors should monitor banking-system liquidity, overnight money-market rates, government bond yields and any additional RBI liquidity operations. These indicators can help show whether the tighter reserve requirement and bond sales are materially changing financial conditions.
For bank investors, the key considerations include funding costs, net interest margins, deposit growth and credit expansion. A tighter liquidity environment can create additional funding pressure, but the effect will depend on each bank’s balance sheet and ability to attract deposits.
Government bond investors will also watch how open market sales influence demand for securities and yields. Larger bond supply from the central bank can place upward pressure on yields, although market expectations, inflation and demand from institutional investors will also matter.
The Bigger Picture
The RBI’s decision highlights the difference between changing the headline CRR rate and changing how strictly banks must maintain the required reserves. By raising the minimum daily maintenance threshold from 90% to 99%, the central bank is reducing operational flexibility while keeping the underlying reserve requirement distinct.
The move also forms part of a wider effort to manage excess liquidity through multiple instruments, including government bond sales. The eventual impact on lending, deposit rates and market yields will depend on how the banking system adjusts and whether the RBI continues to withdraw surplus funds.
Looking Ahead
The new daily maintenance requirement will take effect from October 16, 2026, and its immediate impact should become clearer as banks adjust their treasury operations. Market participants will look for changes in short-term funding rates, liquidity balances and demand for government securities following the RBI’s planned bond sale. Any further action will depend on the central bank’s assessment of liquidity, inflation and wider financial conditions.
For customers, the change is not an automatic signal that loan or deposit rates will move immediately. For banks and investors, however, it is an important operational and liquidity-management development. The central question is whether these measures will gradually reduce the banking system’s surplus cash without creating undue pressure on credit availability or financial-market stability.
