RBI raises banks’ minimum daily CRR maintenance to 99% from October 16 to absorb surplus liquidity
Why this matters
This is a monetary-policy story about how the Reserve Bank of India controls excess money in the banking system without changing the headline reserve ratio. It matters because even a technical change in daily reserve rules can influence overnight interest rates, banks’ lending flexibility and the transmission of policy decisions.
In plain words
This decision sits within the Reserve Bank of India’s liquidity-management framework. Banks must keep a portion of their deposit-related liabilities as cash reserves with the central bank. The overall Cash Reserve Ratio remains 3% of Net Demand and Time Liabilities, but from the fortnight beginning October 16, 2026, banks must maintain at least 99% of that required reserve every day, instead of 90%. The fortnightly average must still equal 100% of the prescribed requirement. (moneycontrol.com)
Earlier, a bank could temporarily hold only 90% of its required reserve on one day and compensate by keeping more reserves later in the same 15-day reporting fortnight. Raising the daily floor to 99% sharply narrows this cushion. It therefore improves the central bank’s day-to-day control over banking-system liquidity, although it does not withdraw liquidity in the same mechanical way as raising the overall reserve ratio. The effect will differ across banks according to their reserve positions and cash-flow management. (moneycontrol.com)
Think of the fortnightly average as a monthly attendance requirement: earlier, a bank could be absent for part of a day and make up for it later; now, it must be present almost every day. The move responds to elevated surplus liquidity, partly linked to foreign-currency deposit inflows. The Reserve Bank has also used variable-rate reverse-repurchase operations, government-bond sales and foreign-exchange swaps to absorb or redistribute excess funds. (moneycontrol.com)
Key facts
- Scheduled banks must maintain at least 99% of their prescribed CRR each day from the fortnight beginning October 16, 2026, up from 90%.
- The overall CRR remains unchanged at 3% of net demand and time liabilities.
- The measure reduces banks’ ability to temporarily fall below the required reserve level and compensate later during the fortnight.
- It is intended to manage surplus banking-system liquidity and improve alignment of overnight money-market rates with the policy stance.
- The liquidity surplus was attributed partly to foreign-currency deposit inflows and other systemic liquidity factors.
How we got here
The legal foundation for reserve requirements is Section 42(1) of the Reserve Bank of India Act, 1934; banking companies are also covered through the Banking Regulation Act, 1949. The daily maintenance floor was reduced from 95% to 90% in the liquidity-management reforms of 2016, giving banks greater flexibility while retaining the fortnightly average requirement. (systemhealth.rbi.org.in)
The headline reserve ratio has moved in stages. In December 2024, the Reserve Bank reduced the ratio from 4.5% to 4% in two 25-basis-point steps, releasing about ₹1.16 lakh crore of primary liquidity. In June 2025, it announced four further 25-basis-point reductions, taking the ratio to 3% from the reporting fortnight beginning November 29, 2025. (rbi.org.in)
In 2026, banking-system liquidity became strongly surplus after capital inflows, including funds attracted through the special FCNR(B) deposit facility. The surplus was subsequently moderated through variable-rate reverse-repurchase operations, open-market bond sales and liquidity outflows, but remained high enough for tighter daily reserve discipline.

The bigger picture
Economic
Liquidity control without changing the headline ratio
The measure is a calibrated instrument: it leaves the 3% Cash Reserve Ratio unchanged but reduces banks’ ability to time their reserve holdings within the fortnight. This can make overnight money-market conditions more responsive to the Reserve Bank’s policy stance. However, because the average requirement remains unchanged, the move is mainly about timing and control rather than a large one-time withdrawal of lendable funds. Its effect will depend on whether banks were actually using the earlier 10% daily cushion. (moneycontrol.com)
The policy tightens daily liquidity discipline more than it changes the structural quantity of reserves.
Economic
Monetary-policy transmission
When surplus funds push overnight market rates below the intended policy corridor, the central bank’s signal becomes weaker. A tighter daily reserve floor can reduce banks’ ability to deploy temporary excess cash and may help overnight rates align more closely with the policy stance. Better transmission can influence deposit pricing, lending rates and asset prices, although the direct impact on credit growth should be modest unless the surplus liquidity is persistent and large. (moneycontrol.com)
Controlling excess liquidity helps the policy rate influence market rates more effectively.
International
Foreign-currency inflows and domestic liquidity
Foreign-currency deposit inflows can increase domestic banking-system liquidity when banks convert or hedge the associated foreign exchange and receive rupee funds. The 2026 surplus was partly associated with the FCNR(B) deposit facility, showing how external capital movements can affect domestic monetary conditions. Such inflows strengthen external financing capacity but may complicate liquidity management and exchange-rate operations if they are sudden or later reversed. (moneycontrol.com)
External capital inflows can create domestic liquidity even without a domestic credit boom.
Historical
Shift from flexibility to finer calibration
The 2016 reform lowered the minimum daily maintenance requirement from 95% to 90% to give banks operational flexibility. The 2026 move partly reverses that flexibility by raising the floor to 99%, while retaining the fortnightly average system. This is not a return to the earlier headline reserve ratio; it is a fine-tuning response to a different problem—excess liquidity rather than an acute shortage of funds. (systemhealth.rbi.org.in)
The change reverses a flexibility measure, not the earlier reductions in the overall reserve ratio.
The big debate
Should the Reserve Bank tighten daily reserve maintenance when surplus liquidity is elevated?
For
- It improves control over overnight liquidity and strengthens transmission of the policy stance without raising the headline reserve ratio.
- It discourages banks from relying on end-of-fortnight adjustment and improves predictability of money-market conditions.
- It is more targeted than a permanent increase in the reserve ratio, which could impose a broader cost on bank intermediation.
Against
- Reduced flexibility may raise banks’ cash-management costs and create temporary stress for institutions with uneven payment flows.
- The measure may have limited effect if surplus liquidity is caused by large external or government-related flows.
- Frequent calibration of reserve rules can complicate treasury planning and may blur the distinction between structural and temporary liquidity tools.
On balance. The measure is justified as a limited, reversible calibration when liquidity is persistently surplus and overnight rates are losing policy alignment. It should not substitute for transparent liquidity forecasting or become a routine burden on banks. The Reserve Bank should review its effects on money-market volatility, credit pricing and smaller banks before making the tighter floor permanent.

How can international capital inflows complicate domestic monetary and liquidity management?
Approach. Use FCNR(B)-related inflows as the hook. Connect external flows with rupee liquidity, exchange-rate management, sterilisation needs and reversal risks, while balancing benefits for external financing against macroeconomic volatility.

Prelims quick-fire
- Term. Cash Reserve Ratio is the share of Net Demand and Time Liabilities banks must maintain as cash reserves with the Reserve Bank. CRR is not the same as Statutory Liquidity Ratio, which is generally maintained in specified liquid assets.
- Data. From the fortnight beginning October 16, 2026, the minimum daily CRR maintenance floor rises from 90% to 99%. The 99% figure is the daily floor, not the new overall CRR ratio.
- Data. The overall CRR remains 3% of Net Demand and Time Liabilities after the October 2026 notification. Do not read the change as a rise in the headline reserve ratio.
- Constitution. Section 42(1) of the Reserve Bank of India Act, 1934 provides the principal legal basis for CRR requirements. The power is statutory, not merely an informal monetary-policy convention.
- Historical. The daily CRR maintenance requirement was reduced from 95% to 90% during liquidity-management reforms in 2016. The 2026 change raises the daily floor but does not restore the earlier headline CRR.
- Body/Institution. The 2025 RBI notification phased the CRR down to 3% through four 25-basis-point reductions. Basis point means one-hundredth of a percentage point; 25 basis points equals 0.25 percentage point.
- International. Surplus liquidity in 2026 was partly linked to inflows through the Foreign Currency Non-Resident Bank deposit facility. FCNR(B) deposits are foreign-currency deposits, not ordinary rupee savings deposits.
- Body/Institution. The Reserve Bank used variable-rate reverse-repurchase operations and open-market bond sales to moderate surplus liquidity. These are liquidity operations; they are distinct from changing the statutory CRR.
What should happen
- Use a transparent liquidity dashboard combining banking-system balances, government cash flows, foreign-currency deposit movements and money-market rates. Better forecasting would allow the Reserve Bank to choose between daily reserve rules and market-based operations according to the source and persistence of surplus liquidity. RBI liquidity-management framework, April 2016
- Treat the 99% floor as a calibrated and reviewable instrument rather than an automatic permanent tightening. Periodic review can preserve operational flexibility while retaining stronger control during episodes of excessive surplus funds. RBI notification on Maintenance of CRR, June 6, 2025
- Prefer a mix of variable-rate reverse-repurchase operations, open-market operations and foreign-exchange swaps for fine-tuning. Multiple instruments can absorb or redistribute liquidity without placing the entire adjustment burden on banks’ reserve balances. RBI Monetary Policy Statement and liquidity operations framework
- Monitor differential effects on small banks, credit availability and overnight-rate volatility. A rule that is manageable for large banks may be costly for institutions with less predictable cash flows and thinner treasury operations.
Jargon, demystified
- Reserve Bank of India (RBI)
- India’s central bank, responsible for monetary policy, banking regulation, currency management and liquidity operations. It uses both statutory rules and market operations to influence financial conditions.
- Cash Reserve Ratio (CRR) and Net Demand and Time Liabilities (NDTL)
- CRR is the required cash reserve; NDTL is the base of demand and time liabilities against which it is calculated. The headline CRR is an average requirement, while the daily maintenance floor controls short-term flexibility.
- Fortnightly average and daily maintenance floor
- Banks meet the required reserve on average over a 15-day reporting period but must also stay above a specified minimum each day. The 2026 change raises the floor from 90% to 99% without changing the average CRR.
- Foreign Currency Non-Resident Bank (FCNR(B)) deposit
- A permitted bank deposit held in foreign currency by eligible non-residents, which can influence domestic rupee liquidity when funds enter India. Do not confuse it with ordinary rupee-denominated non-resident deposits.
- Liquidity Adjustment Facility (LAF), variable-rate reverse-repurchase operation and open-market operation
- Tools used to absorb or inject short-term funds; open-market operations involve buying or selling government securities. These market tools complement, but do not replace, statutory reserve requirements.
- Overnight money market and policy stance
- The overnight money market is where banks lend or borrow for one day; the policy stance is the central bank’s intended direction for financial conditions. Surplus funds can push overnight rates away from the intended policy signal.
- Basis point
- One-hundredth of a percentage point; 100 basis points equal one percentage point. A 25-basis-point change equals 0.25 percentage point.
