CRR vs SLR: Differences, RBI Monetary Tools & Banking Facts
In the macroeconomic management of India's financial system, the Reserve Bank of India (RBI) utilizes quantitative credit control tools to regulate market liquidity, control inflation, and ensure the structural solvency of the commercial banking sector. Among these instruments, the Cash Reserve Ratio (CRR) and the Statutory Liquidity Ratio (SLR) represent the twin reserve requirements that all commercial banks operating in India must legally maintain. While both tools mandate that banks sequester a specified proportion of their Net Demand and Time Liabilities (NDTL) rather than disbursing them as commercial credit, they differ fundamentally in their statutory governance, the forms of eligible assets, the custody of reserves, and their return on investment.
The Cash Reserve Ratio is governed by Section 42(1) of the Reserve Bank of India Act, 1934. Under this provision, scheduled commercial banks are mandated to maintain a specified percentage of their total NDTL exclusively in cash balances deposited directly with the Reserve Bank of India. Crucially, the RBI pays zero interest on these cash balances—a policy cemented by the Reserve Bank of India (Amendment) Act, 2006, which also abolished the statutory floor of 3% and ceiling of 20%, giving the central bank absolute flexibility in fixing the ratio. Because CRR deposits earn no yield and are locked in the vaults of the central bank, adjustments to the CRR serve as a direct, powerful valve to drain excess liquidity or pump immediate funds into the interbank system.
In contrast, the Statutory Liquidity Ratio is governed by Section 24(2A) of the Banking Regulation Act, 1949. Instead of depositing reserves with the central bank, banks maintain the SLR with themselves in the form of approved unencumbered liquid assets. These assets include physical cash in bank vaults, gold valued at current market rates, and designated government securities such as dated Government of India bonds, Treasury bills, and State Development Loans (SDLs). Unlike CRR, the SLR generates investment income because banks earn regular coupon interest and capital yields on their government bond holdings. While the primary objective of CRR is to control money supply and interbank liquidity, the SLR ensures bank solvency against sudden depositor bank runs and secures a guaranteed domestic market for central and state government borrowing programs.

CRR (Cash Reserve Ratio) is governed under Section 42(1) of the Reserve Bank of India Act, 1934.
SLR (Statutory Liquidity Ratio) is governed under Section 24(2A) of the Banking Regulation Act, 1949.
Both reserve requirements are calculated as a percentage of a commercial bank's Net Demand and Time Liabilities (NDTL).
CRR must be maintained exclusively in the form of liquid cash balances held with the Reserve Bank of India.
SLR is maintained by the commercial bank itself in the form of unencumbered liquid assets: cash in vault, gold, or approved government securities.
The RBI pays zero interest on CRR balances deposited by banks (provisions for interest were removed by the 2006 RBI Amendment Act).
Banks earn interest and capital returns on SLR holdings through periodic coupon payments on government bonds and Treasury bills.
The 2006 amendment to the RBI Act abolished the statutory floor (formerly 3%) and ceiling (formerly 20%) on CRR, granting complete policy discretion to RBI.
The Banking Regulation (Amendment) Act, 2007, removed the statutory 25% floor on SLR, but retained a statutory ceiling of 40%.
CRR is primarily a direct monetary policy tool used to expand or contract credit creation capacity and drain or inject interbank liquidity.
SLR ensures the liquidity and solvency of banks against sudden depositor withdrawals while creating a captive institutional market for government debt.
When the RBI increases the CRR, commercial banks have fewer lendable funds, which raises loan interest rates and contracts domestic money supply.
When the RBI cuts the CRR, it immediately releases lendable reserves into the banking system, reducing borrowing costs for enterprises and individuals.
Approved securities for SLR include Government of India Dated Securities, Treasury Bills (91-day, 182-day, 364-day), and State Development Loans (SDLs).
Gold held under SLR must be valued at current market rates not exceeding the closing price in London or designated bullion markets.
Failure to maintain the required daily or fortnightly CRR invites statutory penal interest charged by the RBI on the shortfall amount.
Under the Liquidity Adjustment Facility (LAF), banks can borrow overnight funds from RBI against excess G-Secs held beyond their mandatory SLR quota.
The Marginal Standing Facility (MSF) allows scheduled banks to borrow overnight funds by dipping into their statutory SLR quota up to an approved limit.
The Basel III framework introduced complementary global liquidity standards: the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR).
NDTL encompasses all demand liabilities (current accounts, demand drafts) and time liabilities (fixed deposits, recurring deposits) minus inter-bank deposits.
CRR applies to all Scheduled Commercial Banks, Regional Rural Banks (RRBs), and Urban Cooperative Banks as notified by the RBI.
SLR acts as a structural prudential buffer ensuring that a defined portion of public bank deposits remains safely insulated from commercial lending risks.
