The SLR full form is Statutory Liquidity Ratio — a quantitative monetary policy instrument used by the Reserve Bank of India (RBI) to regulate commercial banks' credit expansion and ensure banking system solvency. The SLR is the minimum percentage of a bank's Net Demand and Time Liabilities (NDTL) that must be maintained in the form of liquid assets — cash, gold, or approved government securities — held with the bank itself.
As of April 2026, the SLR in India stands at 18%, unchanged since April 2020 when RBI cut it from 19% during the COVID-19 liquidity support phase. For UPSC aspirants, SLR is a core concept in banking, monetary policy, and public finance.
Statutory Backing — BR Act 1949
The SLR is prescribed under Section 24 of the Banking Regulation Act, 1949. Key provisions:
- RBI can prescribe SLR up to a maximum of 40%
- Earlier floor was 25%, removed by the Banking Regulation (Amendment) Act, 2007
- The Act gives RBI full discretion to revise SLR upward or downward as warranted by monetary conditions
Components of SLR — Approved Assets
A bank maintains SLR by holding a mix of the following:
| Asset | Description |
|---|---|
| Cash in hand | Vault cash with the bank |
| Gold | Valued at a price not exceeding the current market price |
| Approved securities | Central govt securities, state development loans (SDLs), Treasury Bills |
| Balances with RBI | In excess of CRR requirements |
Notably, demand and time liabilities of RBI held by banks do not qualify as SLR assets.
SLR Formula
The formula is straightforward:
SLR (%) = (Liquid Assets ÷ NDTL) × 100
Where:
- Liquid Assets = Cash + Gold + Approved Securities (held by the bank)
- NDTL (Net Demand and Time Liabilities) = Bank's demand liabilities + time liabilities – inter-bank liabilities
Illustration
If a bank's NDTL is Rs. 100 crore and the SLR is 18%, the bank must hold at least Rs. 18 crore in SLR-eligible assets.
Current SLR Rate and Historical Trajectory
| Period | SLR Rate |
|---|---|
| 1970s–1991 | Around 38–38.5% (peak) |
| 1991 (liberalisation) | Gradual cut began |
| 1997 | 25% |
| 2012 | 23% |
| 2018 | 19.5% → 19% (staggered) |
| April 2020 | 18% (current) |
The steady reduction reflects India's transition from a statutory credit allocation model (funding government borrowing) to a more market-determined monetary framework.
Objectives of SLR
1. Ensure Bank Solvency
SLR assets act as a liquidity cushion. If a bank faces sudden deposit withdrawals, it can liquidate SLR assets to meet obligations.
2. Regulate Credit Expansion
By raising SLR, RBI reduces the portion of deposits available for lending — a contractionary tool.
3. Finance Government Borrowing
Since most SLR assets are government securities, SLR indirectly channels bank funds to fund the fiscal deficit. This is a form of captive demand for G-Secs.
4. Monetary Policy Transmission
SLR interacts with CRR, repo rate, and MSF to influence money supply, inflation, and interest rates.
5. Prevent Asset Bubbles
Restraining credit growth prevents overheating in specific sectors (real estate, unsecured lending).
SLR vs CRR — The Critical Distinction
Both SLR and CRR are reserve requirements, but they differ sharply in mechanics and purpose:
| Parameter | SLR (Statutory Liquidity Ratio) | CRR (Cash Reserve Ratio) |
|---|---|---|
| Meaning | Liquid assets as % of NDTL | Cash reserves as % of NDTL |
| Held with | The bank itself | The RBI |
| Form | Cash + Gold + Govt securities | Cash only |
| Earns interest | Yes (on G-Secs and gold) | No (non-interest bearing) |
| Legal basis | BR Act 1949, Section 24 | RBI Act 1934, Section 42(1) |
| Maximum limit | 40% | No upper limit (earlier 15%) |
| Current rate (2026) | 18% | 4% |
| Primary purpose | Solvency + govt borrowing | Liquidity control |
Impact of SLR Changes
When RBI Increases SLR
- Banks must park more funds in government securities/liquid assets
- Loanable funds decrease
- Lending rates tend to rise
- Inflation pressure eases (contractionary)
- Government borrowing is cushioned
When RBI Decreases SLR
- Banks have more funds for credit
- Lending rates tend to fall
- Credit growth and investment are stimulated
- Inflation risk may rise (expansionary)
The April 2020 cut from 19% to 18% was a COVID-era measure — designed to boost credit flow to stressed sectors.
SLR-Eligible Securities — What Counts
Per RBI's Master Circular on SLR, the following qualify:
| Category | Examples |
|---|---|
| Central Government Securities | Dated G-Secs issued by Central Govt |
| State Development Loans (SDLs) | State government securities |
| Treasury Bills | 91-day, 182-day, 364-day T-Bills |
| Oil Bonds, Special Securities | Notified by RBI as SLR-eligible |
| Cash | Vault cash |
| Gold | At current market valuation |
Notably, corporate bonds, state government guaranteed bonds not specifically notified, and equity are not SLR-eligible.
Penalty for Shortfall
If a bank fails to maintain SLR:
- RBI charges penal interest on the shortfall for the day
- First-day shortfall: Bank Rate + 3%
- Continuing shortfall: Bank Rate + 5%
- Repeat violations attract regulatory action under BR Act
SLR and the Broader Monetary Toolkit
SLR is part of a family of quantitative monetary instruments:
| Tool | Mechanism |
|---|---|
| CRR | Cash with RBI, non-interest bearing |
| SLR | Liquid assets with bank, interest-bearing |
| Repo Rate | Rate at which RBI lends overnight to banks |
| Reverse Repo | Rate at which RBI absorbs liquidity |
| MSF (Marginal Standing Facility) | Emergency overnight borrowing |
| OMO (Open Market Operations) | RBI's buy/sell of G-Secs |
SLR is generally viewed as a structural tool, while CRR and repo rate are used for fine-tuning.
SLR and Financial Repression — A Critique
Economists historically criticised high SLR as a form of financial repression:
- Forces banks to fund government deficits at below-market rates
- Crowds out private sector lending
- Distorts bank balance sheets
- The Narasimham Committee (1991) recommended phased reduction
However, in a bank-dominated financial system like India's, SLR also provides systemic stability — a point underscored during global financial crises.
Recent Policy Context
- April 2020: SLR cut to 18% to support COVID-era credit flow
- HTM (Held-to-Maturity) limits periodically relaxed to facilitate bank G-Sec holdings
- RBI's Financial Stability Reports track SLR holdings as a solvency metric
- The combined CRR (4%) + SLR (18%) = 22% of NDTL is locked away from active lending
