RBI raises daily CRR maintenance to 99% for banks from Oct 16
Synopsis
The RBI has sharply curtailed the daily flexibility banks enjoyed under CRR maintenance rules, pushing the threshold from 90% to 99% with effect from 16 October. The move is a precision liquidity management tool deployed against a backdrop of ₹3.92 lakh crore in system surplus — and signals the central bank is tightening the plumbing even as it holds its policy rate steady.
Key Takeaways
The RBI has raised the minimum daily CRR maintenance requirement for banks from 90% to 99% of the prescribed ratio.
The revised norm takes effect from the reporting fortnight beginning 16 October 2026 .
The overall CRR ratio has not been changed; only the daily compliance floor has been raised.
Banking system liquidity surplus stood at ₹3.92 lakh crore as of the latest data, down from an average of ₹5.9 lakh crore since the August MPC meeting.
RBI Governor Sanjay Malhotra had flagged gradual liquidity easing at the 7 October monetary policy review.
The RBI will continue to use VRRR auctions, OMO sales, and dollar-rupee swaps to manage system liquidity.
The Reserve Bank of India (RBI) on Friday, 9 October 2026, announced a tightening of cash reserve ratio (CRR) maintenance norms, raising the minimum daily maintenance requirement for banks from the existing 90% to 99% of their prescribed CRR. The revised rule takes effect from the reporting fortnight beginning 16 October 2026.
What the New Rule Changes
Under the existing framework, banks were required to maintain an average daily CRR balance equal to the prescribed requirement over a fortnight, with the flexibility to dip as low as 90% of that requirement on any individual day. The updated notification nearly eliminates that intraday flexibility, requiring banks to hold 99% of the prescribed CRR on each working day. Notably, the RBI has not altered the overall CRR ratio itself — the change is purely a tightening of daily compliance thresholds.
Why the RBI Moved Now
The timing follows RBI Governor Sanjay Malhotra's remarks during the 7 October monetary policy review, in which he flagged that surplus liquidity in the banking system was expected to ease gradually through the remainder of the financial year due to natural liquidity-draining factors. Banking system liquidity had surged during August and September following strong capital inflows, including funds mobilised through the central bank's special foreign currency non-resident bank (FCNR-B) deposit facility.
The surplus has since moderated after the RBI conducted variable rate reverse repo (VRRR) auctions and open market operation (OMO) bond sales, alongside other liquidity outflows. According to RBI data, the average daily liquidity surplus under the liquidity adjustment facility (LAF) stood at ₹5.9 lakh crore since the August meeting of the Monetary Policy Committee (MPC), with the latest reading showing the surplus at ₹3.92 lakh crore.
Impact on Banks
The impact of the revised norm is expected to vary across banks depending on their individual liquidity positions and treasury management practices. Lenders that routinely operate close to the minimum reserve threshold may need to restructure their day-to-day liquidity planning to stay compliant. The move effectively limits the room banks previously had to deploy reserve balances more aggressively on a daily basis.
RBI's Broader Liquidity Toolkit
The central bank reiterated that it would continue to closely monitor liquidity conditions and deploy appropriate instruments as warranted. These include VRRR auctions, dollar-rupee sell-buy swaps, and OMO operations, all aimed at ensuring orderly liquidity conditions across the financial system. The latest CRR norm change is best understood as a calibration tool — not a pivot in monetary stance — designed to prevent excess liquidity from re-accumulating at the short end of the market.
Point of View
Not a blunt instrument. By tightening the daily CRR floor rather than hiking the ratio itself, the RBI is signalling that its concern is with the pattern of reserve management — banks drawing down buffers on high-demand days — rather than the aggregate level of reserves. That distinction matters: it does not tighten credit conditions for borrowers, but it does constrain treasury desks that have grown accustomed to playing the daily band. The backdrop of ₹3.92 lakh crore in surplus liquidity explains why the RBI feels comfortable moving now. The real question is whether this is a standalone calibration or the first in a sequence of measures to normalise the post-FCNR inflow overhang before the fiscal year closes.

Frequently Asked Questions
What has the RBI changed about the CRR maintenance norm?
The RBI has raised the minimum daily cash reserve ratio (CRR) maintenance requirement for banks from 90% to 99% of the prescribed CRR, effective from the reporting fortnight beginning 16 October 2026. The overall CRR ratio itself has not been changed.
When does the new CRR daily maintenance rule take effect?
The revised norm comes into force from the reporting fortnight beginning 16 October 2026. Banks will need to ensure their daily reserve balances meet 99% of their prescribed CRR from that date onwards.
Why has the RBI tightened the daily CRR requirement now?
The RBI is looking to tighten daily liquidity management after banking system liquidity surged during August and September 2026, driven by strong capital inflows including the FCNR-B deposit facility. Governor Sanjay Malhotra had flagged at the 7 October monetary policy review that surplus liquidity was expected to ease gradually.
How does this affect banks?
Banks that routinely operated near the 90% daily floor will need to restructure their treasury and liquidity management. The change significantly reduces the intraday flexibility banks had to deploy reserve balances, though it does not alter the overall CRR level or directly tighten lending conditions.
What is the current banking system liquidity surplus?
According to RBI data, the banking system's liquidity surplus stood at ₹3.92 lakh crore as of the latest reading, down from an average daily surplus of ₹5.9 lakh crore recorded since the August Monetary Policy Committee meeting.
