Every rupee deposited in a bank cannot be used for lending. Banks are required to keep a portion of their deposits in reserve. One such requirement is the Statutory Liquidity Ratio (SLR), a key tool used by the RBI. It requires banks to maintain a minimum percentage of their deposits in liquid assets such as cash, gold, and government securities. This helps ensure that banks remain financially stable and have enough funds to meet customer withdrawals and other.
Understanding the Statutory Liquidity Ratio (SLR)
The Statutory Liquidity Ratio refers to the mandatory minimum percentage of a bank's Net Demand and Time Liabilities (NDTL which needs to be maintained as liquid assets at the end of every banking day.
This ratio comes into effect under Section 24 of the Banking Regulation Act, 1949, and is controlled by the Reserve Bank of India (RBI). The Banking Regulation Act permits the RBI to prescribe an SLR of up to 40% of NDTL, although the prevailing requirement is significantly lower.
Let's try to understand it with a simple example. Suppose a bank having ₹100 worth of liabilities must maintain at least ₹18 in eligible SLR assets.
Why Does RBI Require Banks to Maintain SLR?
SLR serves several purposes simultaneously. It ensures banks have enough funds during stress periods by keeping a portion of their funds in assets that can be liquidated quickly. It also helps the RBI manage money supply across the economy.
When the RBI raises SLR, banks have less money available to lend, credit tightens and inflation reduces. When SLR is lowered, more funds flow into the credit market, supporting growth. This makes SLR a monetary policy instrument.
Beyond liquidity management, SLR channels a portion of bank funds into government securities. This supports the government's borrowing programme by creating a steady institutional demand for sovereign debt, particularly Treasury Bills, dated Government of India (GOI) securities, and State Development Loans (SDLs).
Components of the Statutory Liquidity Ratio
The SLR is calculated using two key components: liquid assets and Net Demand and Time Liabilities (NDTL). Understanding these elements helps explain how banks determine their SLR requirements.
Liquid Assets
Eligible SLR assets include cash, gold, and unencumbered government securities (assets free from any claims liens, or pledges), specifically dated GOI securities, Treasury Bills, and State Development Loans, along with certain balances maintained with the RBI.
Worth noting, only the unencumbered portion of approved securities qualifies as SLR assets for compliance purposes. Securities pledged as collateral are generally treated as encumbered, and therefore excluded, with specific carve-outs for certain RBI-approved liquidity facilities.
Net Demand and Time Liabilities (NDTL)
NDTL is the denominator in the SLR calculation. It represents a bank's total liabilities to the public, both demand liabilities (amounts repayable on demand, such as current accounts and call deposits) and time liabilities (amounts repayable after a fixed period, such as fixed deposits and recurring deposits), minus claims on other banks.
Funds borrowed under repo in government securities are exempt from CRR and SLR computation, while securities acquired under such repos are eligible for SLR maintenance.
How is SLR Calculated?
The formula is straightforward:
SLR (%) = (Liquid Assets ÷ Net Demand and Time Liabilities) × 100
Example:
Suppose a bank has NDTL of ₹5,000 crore. At the current SLR of 18%, it must hold at least ₹900 crore in eligible liquid assets. If it holds ₹950 crore, it is compliant with a small buffer. If it holds only ₹850 crore, it is in shortfall, and penalties apply.
NDTL figures must be certified by statutory auditors, adding an independent verification layer to the compliance process.
How SLR Influences Bank Lending and Liquidity
SLR directly constrains the volume of funds a bank may deploy as credit. This reflects the RBI's design intent. When a larger share of deposits must be stored in approved securities, the pool available for commercial lending shrinks.
This is particularly relevant in a falling interest rate environment. At its 58th Monetary Policy Committee meeting held from December 3–5, 2025, the RBI kept the SLR unchanged at 18.00%, alongside policy rate reductions, and opted instead to inject liquidity through open market operations (OMOs) and foreign exchange swaps. Maintaining the SLR while using non-statutory tools suggests the RBI is preserving structural liquidity buffers even as it eases borrowing costs.
From a banking operations perspective, the SLR also creates a channel through which banks participate in the government securities market. Banks are among the largest holders of G-Secs in India precisely because of this obligation.
Importance of SLR in the Indian Financial System
SLR plays three distinct roles in the Indian financial system:
- Depositor protection. By requiring banks to hold liquid assets, SLR reduces the likelihood of a bank being unable to meet withdrawal demands during periods of stress.
- Monetary transmission. The RBI uses SLR alongside the repo rate and Cash Reserve Ratio (CRR) to manage liquidity conditions. A change in SLR affects how much credit the banking system can create, influencing interest rates across the economy.
- Sovereign borrowing support. SLR-eligible assets are predominantly government securities. The mandatory holding requirement creates consistent institutional demand for these instruments, helping the government finance its fiscal deficit at relatively lower costs.
SLR vs CRR: Key Differences
CRR (Cash Reserve Ratio) is another tool used by the RBI. It is the portion of deposits that banks must keep as cash with the RBI to help regulate liquidity in the economy. It is important to understand how SLR and CRR differ.
| Feature | SLR | CRR |
|---|---|---|
| Full form | Statutory Liquidity Ratio | Cash Reserve Ratio |
| What is maintained | Liquid assets (cash, gold, G-Secs) | Cash only |
| Where held | With the bank itself (in eligible assets) | Deposited with RBI |
| Current rate | 18.00% | 3.00% |
| Interest earned | Yes (on G-Secs held) | No |
| Primary purpose | Liquidity + sovereign debt support | Controlling money supply |
What Happens if Banks Fail to Maintain SLR?
Not following the rules may lead to financial penalties..
Following the December 5, 2025 Monetary Policy Statement, penal interest rates on SLR shortfalls were reduced to 10.50% per annum in line with the revised Bank Rate. This penalty rate applies to the amount of shortfall for each day the bank remains non-compliant.
Persistent default may lead to cancellation of a bank's banking licence, and late submission of statutory returns attracts penalties under Sections 42(4) and 46(4) of the RBI Act.
In practice, SLR shortfalls in large commercial banks are uncommon. Most banks maintain SLR holdings above the minimum requirement, partly as a buffer and partly because government securities remain a core part of their investment portfolios.
Current SLR Requirement in India
As confirmed at the RBI's 58th MPC meeting on December 5, 2025, the Statutory Liquidity Ratio stands at 18.00%. (Figures are subject to change based on RBI policy decisions.)
The RBI (Commercial Banks – Cash Reserve Ratio and Statutory Liquidity Ratio) Directions, 2025 set out updated rules for banks' reserve maintenance, reporting, and compliance, effective immediately across commercial banks. These Directions consolidate and modernise the earlier regulatory framework, with NDTL computation rules and eligible asset definitions updated to reflect current market instruments.
Conclusion
The Statutory Liquidity Ratio is a foundational pillar of India's banking regulation. It protects depositors, supports the government's borrowing programme, and gives the RBI a tool to calibrate credit flows in the economy. At 18% of NDTL, it represents a meaningful constraint on bank lending, and a meaningful safeguard for financial stability. For anyone seeking to understand how Indian banks are regulated, or how the fixed-income market in India is structured, SLR is a concept worth understanding clearly.
FAQs on Statutory Liquidity Ratio
What is the current SLR rate in India?
The RBI has currently fixed the SLR at 18.00% of the NDTL of the banks up till December 5, 2025. This figure may fluctuate according to the need for monetary policies.
Who determines the SLR in India?
The Reserve Bank of India decides and changes the SLR in accordance with section 24 of the Banking Regulation Act of 1949.

Whereas SLR assets require banks to hold liquid assets like cash, gold, and government securities, CRR demands that banks deposit cash reserves with the central bank, which doesn’t yield coupons, unlike SLR assets.
Why is SLR important for banks?
The SLR is crucial for banks for ensuring liquidity, fulfilling the needs of their depositors, and maintaining stability in the financial markets.
What assets qualify for SLR maintenance?
Assets eligible for holding as SLRs include cash, gold, treasury bills, securities of the government of India, SDLs, and RBI balances.
