RBI raises daily cash reserve ratio requirement for banks

1. At a Glance

• The RBI has raised the share of the required Cash Reserve Ratio (CRR) that banks must hold every day from 90% to 99%, starting October 16 [1].
• The CRR rate itself has not changed. Only the daily minimum balance banks must keep within the reporting fortnight has gone up [1][2].
• The aim is to absorb surplus liquidity in the banking system, which was about ₹3.88 lakh crore as of October 8 [1].
• For UPSC this links to monetary policy tools, liquidity management, the Liquidity Adjustment Facility (LAF), and the gap between the policy rate and the overnight call rate (GS-III, Indian Economy).

2. Why in the News

• On Friday, 9 October 2026, the RBI announced that banks must maintain 99% of the required CRR daily from 16 October 2026, up from 90% [1].
• The RBI said the move follows a review of current liquidity conditions in the banking system [1].
• It is meant to reduce banking-system liquidity, which was in surplus by about ₹3.88 lakh crore on 8 October 2026 [1].
• The report was a PTI story in The Hindu, Chennai edition, 10 October 2026, page 19 [1].

3. Background & Evolution

• Legal origin: CRR is prescribed under Section 42(1) of the RBI Act, 1934. Scheduled banks must keep a cash balance with the RBI equal to a set percentage of their Net Demand and Time Liabilities (NDTL) [2].
• 2006 amendment: The statutory floor of 3% and ceiling of 20% on CRR was removed, so the RBI can now set it at its discretion [2].
• Averaging system: Banks meet CRR as an average over a fortnight. A daily minimum (a percentage of the requirement) stops banks from keeping very low balances on some days [2].
• Milestones in the daily minimum [2]:
• July 2013: raised to 99% (from 70%) to tighten liquidity and defend the rupee during the "taper tantrum". This is the closest precedent to the current move.
• September 2013: eased to 95%.
• April 2016: eased to 90%.
• March 2020 (COVID): temporarily cut to 80%, then restored to 90% in September 2020.

• October 2026: raised to 99% [1].

• Recent CRR rate path [2]: 4.5% (May 2022) → 4% (December 2024) → 3% after a 100 bps cut announced in June 2025 and carried out in tranches from September to November 2025.

4. Core Static Facts

5. Multi-Dimensional Analysis

Economic / Monetary

• The move takes out surplus liquidity of about ₹3.88 lakh crore [1] without changing the policy rate or the headline CRR. That makes it a calibrated, low-signal tightening.
• A large surplus pushes overnight rates (WACR) toward the SDF floor, which weakens policy transmission. A higher daily minimum pulls the operating target back toward the repo rate [2].
• Banks lose day-to-day flexibility. They can no longer run their RBI balances down to 90% on some days and make up the shortfall later in the fortnight [2].

Financial Stability / Banking

• Banks will need to plan their treasury cash flows more tightly. Demand for call money and TREPS borrowing may rise around large outflows such as advance-tax dates [2].
• The RBI used the same lever in 2013 for rupee and currency stability [2]. That suggests the move may also have a currency or capital-flow angle, though the article only cites liquidity [1].

Governance / Policy Design

• This is an operational lever outside the MPC. The RBI can adjust liquidity between policy meetings without changing its stance [2].
• It complements other tools such as VRRR auctions, OMO sales and the SDF [2].

Legal / Institutional

• The RBI's discretion comes from Sec. 42 of the RBI Act, which has had no statutory floor or ceiling since 2006 [2].

6. Recent Developments (last 12–18 months)

• June 2025: RBI announced a 100 bps CRR cut to 3%, carried out in four tranches between September and November 2025 [2].
• 8 October 2026: banking-system liquidity surplus was about ₹3.88 lakh crore [1].
• 9 October 2026: RBI announced the daily CRR minimum would rise from 90% to 99% [1].
• 16 October 2026: the new 99% daily requirement takes effect [1].

7. Prelims Hooks

• From 16 October 2026, banks must keep 99% of required CRR daily, up from 90% [1].
• The headline CRR rate was not changed. Only the daily maintenance threshold changed [1].
• The stated reason was a review of liquidity conditions, with a surplus of about ₹3.88 lakh crore on 8 October 2026 [1].
• CRR is mandated under Section 42 of the RBI Act, 1934 [2].
• SLR is mandated under Section 24 of the Banking Regulation Act, 1949 [2].
• CRR is calculated on Net Demand and Time Liabilities (NDTL) [2].
• The RBI pays no interest on CRR balances [2].
• CRR is decided by the RBI, not the MPC [2].
• The 2006 amendment removed the 3% floor and 20% ceiling on CRR [2].
• The daily minimum was 99% in July 2013 (taper-tantrum response) and was cut to 90% in April 2016 [2].
• A higher daily CRR minimum reduces system liquidity, so it is a tightening measure [1].

8. Why the RBI Changed Its Own Rule Within a Year

• The RBI had just confirmed the 90% rule a year earlier
• On 30 September 2025, the RBI issued its revised liquidity management framework. It said banks would keep maintaining at least 90% of CRR every day [3].
• That framework followed a review by an RBI Internal Working Group (IWG), whose report came out on 6 August 2025 [3].

• Raising the daily minimum to 99% about 12 months later shows that the 'normal' setting could not handle the current surplus.

• A rate rise does not work if overnight money stays cheap

• Business Standard reports that this move came just after a rate rise [4].
• The RBI keeps the overnight call rate, WACR (the average rate at which banks lend to each other for one day), close to the repo rate. The floor sits 25 bps below the repo rate (the SDF) and the ceiling 25 bps above it (the MSF) [3].
• With a surplus of about ₹3.88 lakh crore [1], banks have spare cash. They lend it cheaply, so the call rate sinks towards the floor.

• So the policy rate goes up, but the rate banks actually pay each other does not follow. The 99% rule supports the rate rise by taking away some of that spare cash.

• It partly cuts against the 2025 CRR cut

• The 2025 CRR cut to 3% was meant to release money into banks (see section 3).
• The RBI did not reverse that cut. It tightened only the daily rule. That lets it drain cash for now without publicly undoing a recent decision.

9. Why 99% Almost Ends Fortnight Averaging

• Averaging exists so banks can absorb sudden cash flows
• Under averaging, a bank can hold less on a day of heavy withdrawals and more later in the fortnight.
• At 90%, a bank could fall 10% below its requirement on any day. At 99%, the room is only 1%.

• In practice, CRR becomes almost a daily requirement. Averaging stays in the rules but loses most of its use.

• The shock now goes to the call money market instead

• A bank hit by large outflows, such as on tax-payment days, can no longer draw down its RBI balance.
• It has to borrow overnight or use the MSF (the RBI's emergency overnight window, priced 25 bps above repo) [3].

• This is the intended effect, since it pushes call rates up. The risk is sharp one-day spikes in the call rate that have nothing to do with the policy stance.

• It drains less money than the headline suggests

• The fortnightly CRR amount is unchanged. Banks must still hold the same average.
• What changes is how low they can go on a single day. The rule takes away cash banks could have lent on some days. It does not remove the whole ₹3.88 lakh crore surplus [1].
• So the bigger job of draining the surplus still falls on the RBI's main tool, 7-day VRRR auctions [3].

10. Why Not Just Use Reverse Repo Auctions?

• The case against the move
• The RBI's own 2025 framework names 7-day VRR/VRRR auctions as the main way to manage liquidity [3]. (In a VRRR auction, banks park spare cash with the RBI for a few days and earn interest.)
• Those auctions let the market find a price. Banks choose how much to park and at what rate.
• A stricter CRR rule does the opposite. It forces banks to lock up cash and pays them nothing for it (see section 4).

• That works like a hidden tax on banks. Some of the cost may reach borrowers as higher loan rates or depositors as lower deposit rates.

• What this argument gets right

• Money locked as CRR earns nothing. Using CRR to manage liquidity does cost banks, and that cost is not visible in any policy rate.

• It also adds another lever outside the MPC, which makes the RBI's signals harder to read.

• Why the RBI may still prefer it

• VRRR has a cost for the RBI, which pays interest on every rupee it absorbs. With a ₹3.88 lakh crore surplus [1], that bill is large.
• VRRR depends on banks choosing to bid. If they prefer to keep the cash, the auction can fall short. A CRR rule applies to every bank, every day.
• Verdict: this works well as a short-term top-up to VRRR, but it is a poor permanent tool. The 2013 precedent fits that view: the 99% level was eased to 95% within about two months (see section 3).

11. How to Tell Whether It Worked

• Watch where WACR sits inside the corridor
• The goal is to bring WACR from near the SDF floor back up towards the repo rate [3].

• If WACR stays near the floor after 16 October [1], the drain was too small and the RBI will need bigger VRRR auctions or OMO sales.

• Watch how quickly the rule is relaxed

• Easing back to 90–95% within months, as in 2013, would show it was a short-term tool.
• If 99% stays in place for long, it would quietly reverse the averaging system that the 2025 framework kept [3]. That would deserve a formal review, not just a press release.

12. Anchors for Answers

• Data: Banking-system liquidity surplus of about ₹3.88 lakh crore on 8 October 2026 is the surplus this move targets [1]
• Data: The corridor is SDF at repo − 25 bps and MSF at repo + 25 bps, and WACR is the operating target [3]
• Report/Committee: RBI Internal Working Group to Review the Liquidity Management Framework (report released 6 August 2025). The final framework of 30 September 2025 kept the 90% daily CRR minimum and made 7-day VRR/VRRR the main operation [3]
• Law/Case: Section 42(1), RBI Act, 1934, is the legal basis for CRR. The statutory floor and ceiling were removed in 2006.

15. NCERT Concepts to Revise

• Cash Reserve Ratio (Economy): The note's core subject: the share of deposits banks must park with the RBI, now with a stricter daily minimum.
• Banking system liquidity (Economy): The move aims to soak up a ₹3.88 lakh crore surplus; this explains what surplus liquidity means.
• Net Demand and Time Liabilities (Economy): CRR is calculated as a percentage of NDTL, so you need this base to understand the requirement.
• Liquidity Adjustment Facility (Economy): The RBI's day-to-day liquidity framework, which this daily CRR change supports by keeping rates near the policy corridor.
• Monetary policy transmission (Economy): Excess surplus liquidity weakens how policy rate changes reach market rates, which is why the RBI tightened.
• Statutory Liquidity Ratio (Economy): SLR is often confused with CRR; knowing the difference helps avoid common exam traps.

16. Common Errors / Trap Areas

• Rate vs. daily minimum: The CRR rate did not rise. Only the share of it that must be held daily went from 90% to 99% [1].
• Wrong statute: CRR is under the RBI Act, 1934 (Sec. 42). SLR is under the BR Act, 1949 (Sec. 24) [2].
• Wrong authority: CRR is set by the RBI, not the MPC [2].
• Interest on reserves: Balances held for CRR earn no interest. SLR assets, such as G-secs, do earn returns [2].
• Direction of effect: A higher daily minimum drains liquidity. It does not inject it [1].
