RBI's New CRR Rule 2026: Key facts, 90% to 99% CRR, NDTL, Liquidity Management Instruments, Basel III Liquidity Standards, Impact, Significance and Challenges

Why in news?

On 9 October 2026, the Reserve Bank of India (RBI) announced an increase in the minimum daily Cash Reserve Ratio (CRR) maintenance requirement from 90% to 99%.

Key Facts

What is CRR (Cash Reserve Ratio)?

• The percentage of a bank's Net Demand and Time Liabilities that must be maintained as cash balances with the RBI. 
• Banks cannot freely use their mandatory CRR balances for lending or investment. RBI does not pay interest on mandatory CRR balances.
• By adjusting CRR requirements, RBI can influence the amount of money available in the banking system.

Eg. Suppose a bank has Net Demand and Time Liabilities of ₹1,000 crore. At a CRR of 3%: Required CRR is 30 crore. The bank must maintain an average CRR balance of ₹30 crore with RBI over the prescribed reporting fortnight.

What exactly has RBI changed?

• RBI has not increased the CRR rate from 3% to 99%. It has increased the minimum proportion of the required CRR that banks must maintain every day. 
  • Earlier: 90% minimum daily maintenance of prescribed CRR
  • From 16 October: 99% minimum daily maintenance of prescribed CRR
  • Actual CRR rate: 3% unchanged

Eg. If the required CRR is ₹30 crore:

What is Net Demand and Time Liabilities (NDTL)?

• The liability base used to calculate CRR and certain other statutory banking requirements.
  • Demand Liabilities: Deposits or other qualifying liabilities payable on demand, such as current account balances.
  • Time Liabilities: Deposits and other qualifying liabilities payable after a specified period, such as fixed deposits.
  • Net Liabilities: The applicable liability base after adjustments prescribed by RBI, including relevant interbank liabilities and exemptions.
• CRR is calculated on the prescribed NDTL base, not simply on a bank's total assets or the sum of every deposit without adjustment.

Why has RBI increased daily CRR maintenance?

• Excess Liquidity in the Banking System
  • India's banking system experienced substantial surplus liquidity during August and September 2026.
  • Excess liquidity can push short-term money-market interest rates below the policy rate and complicate monetary policy transmission. 
• Better Control Over Daily Bank Reserves
  • Previously, banks could temporarily maintain only 90% of their required CRR and compensate by maintaining higher balances on other days.
  • The 99% rule significantly reduces this flexibility. It helps RBI manage short-term liquidity conditions more closely.
• Strengthening Monetary Policy Transmission
  • RBI raised the policy repo rate by 25 basis points to 5.50% in October 2026.
  • Excess liquidity can weaken the transmission of monetary tightening to overnight market rates.
  • Tighter daily reserve requirements, combined with other liquidity operations, can support closer alignment between money-market rates and the policy stance. 
• Liquidity Created Through Foreign Currency Inflows
  • Foreign Currency Non-Resident Bank deposits, or FCNR (B) deposits, contributed to banking-system liquidity.
  • Banks mobilised foreign currency deposits, and subsequent foreign-exchange swap operations helped provide rupee liquidity.
  • Government expenditure also contributed to temporary liquidity surpluses. 

How will the New Rule affect the Banking System?

• Daily CRR minimum rises to 99% 
• Banks have less flexibility to draw down reserve balances
• More disciplined daily liquidity management
• Potentially tighter overnight money-market conditions

Liquidity Management Instruments Used by RBI

• Open Market Operations (OMO)
  • Refers to RBI's purchase or sale of government securities in the financial market.
  • OMO Purchase: RBI buys government securities and injects liquidity into the banking system.
  • OMO Sale: RBI sells government securities and absorbs liquidity from the banking system.
  • On 9 October 2026, RBI announced an OMO sale of ₹25,000 crore for 13 October.
• Repo Rate
  • The repo rate is the policy interest rate at which RBI provides liquidity to eligible banks against approved securities through repurchase agreements.
  • A higher repo rate generally makes borrowing from RBI more expensive and supports tighter monetary conditions. In October 2026, the repo rate was increased to 5.50%.
• Standing Deposit Facility (SDF)
  • SDF allows RBI to absorb surplus liquidity from eligible banks without providing collateral.
  • It operates as the floor of the Liquidity Adjustment Facility (LAF) corridor under normal conditions.
• Variable Rate Reverse Repo (VRRR)
  • VRRR auctions allow RBI to absorb surplus banking-system liquidity for specified periods at market-determined auction rates.
  • They are particularly useful when excess liquidity is temporary.
• Marginal Standing Facility (MSF)
  • MSF provides an emergency overnight borrowing facility for eligible banks against permitted securities.
  • It normally forms the upper boundary of the LAF interest-rate corridor.

CRR vs SLR

Basel Standards and Their Relationship with CRR

• The Basel framework is developed by the Basel Committee on Banking Supervision (BCBS), based in Basel, Switzerland, and supported by the Bank for International Settlements (BIS).
• Its objective is to improve banking stability through stronger capital, liquidity and risk-management requirements.

Evolution of Basel Standards

Basel III: Three Major Pillars

• Pillar 1 (Minimum Capital Requirements): Banks must maintain regulatory capital against credit, market and operational risks.
• Pillar 2 (Supervisory Review): Regulators evaluate banks' risk management, capital adequacy and overall financial resilience.
• Pillar 3 (Market Discipline): Banks disclose financial and risk-related information to promote transparency.

Important Basel III Liquidity Standards

• Liquidity Coverage Ratio (LCR): Ensures that banks hold sufficient High-Quality Liquid Assets (HQLA) to withstand net cash outflows during a 30-day stress scenario.

• Net Stable Funding Ratio (NSFR): Ensures that banks maintain stable funding relative to their assets and activities over a one-year horizon.

Difference between CRR, LCR and NSFR

Impact of RBI's Decision 

• Impact on Banks
  • Banks will need to manage daily reserve balances more carefully.
  • Their flexibility to temporarily use CRR balances for other liquidity needs will decrease.
  • Some banks may rely more on interbank borrowing or RBI liquidity facilities to meet short-term funding requirements.
  • The actual cost impact will depend on individual banks' liquidity positions.
• Impact on Lending and Borrowers
  • The revised rule does not directly increase lending interest rates.
  • However, if it contributes to tighter money-market conditions, banks' short-term funding costs could increase.
  • The impact on home loans, personal loans, business loans and MSME credit will depend on broader monetary conditions and banks' pricing decisions.
• Impact on Inflation
  • Tighter liquidity conditions can support RBI's efforts to control inflation by influencing credit conditions and short-term interest rates.
  • However, the daily CRR maintenance change alone is unlikely to produce a large, immediate reduction in inflation.
• Impact on Financial Markets
  • Money Market: Overnight interest rates may face upward pressure if surplus liquidity declines.
  • Bond Market: OMO sales can increase the supply of government securities in the market, potentially putting upward pressure on bond yields.
  • Banking Sector: Banks may need more active treasury and liquidity management.
  • Exchange Rate: Liquidity tightening can influence rupee funding conditions, although exchange rates depend on several domestic and international factors.

Significance 

• Monetary Policy Effectiveness: Helps RBI maintain better control over short-term banking liquidity.
• Financial Discipline: Encourages banks to maintain reserve balances closer to the prescribed requirement each day.
• Liquidity Stability: Reduces excessive daily fluctuations in banks' use of mandatory reserves.
• Policy Coordination: Complements repo-rate decisions, OMO sales and other liquidity management operations.
• Financial Stability: Supports more predictable reserve management without changing the overall CRR rate.

Challenges 

• Reduced Flexibility: Banks have less freedom to manage temporary daily liquidity shortages.
• Funding Costs: Banks with tighter liquidity positions may face higher short-term borrowing costs.
• Uneven Impact: Smaller or less liquid banks may experience greater adjustment pressures than banks holding substantial excess reserves.
• Credit Transmission: Excessive liquidity tightening could affect credit conditions if combined with other restrictive measures.
• Market Volatility: Rapid changes in liquidity conditions may influence overnight interest rates and bond yields.
