What is the Statutory Liquidity Ratio (SLR)? Formula, Components and Current SLR Rate
The banking system does not lend every rupee deposited by customers. A certain portion must always be kept safely aside in liquid assets to maintain financial stability and manage economic risks. This reserve requirement is known as the Statutory Liquidity Ratio (SLR).
What is the Statutory Liquidity Ratio (SLR)?
The Statutory Liquidity Ratio (SLR) is the minimum percentage of deposits that banks in India must maintain in the form of liquid assets, such as
- Cash
- Gold
- Government-approved securities
It is set by the Reserve Bank of India to ensure banks remain financially stable and always have enough liquidity to handle withdrawals or financial stress.
As of May 2026, the current SLR rate is 18%.
Objectives of Statutory Liquidity Ratio (SLR)
The main objective of the Statutory Liquidity Ratio (SLR) is to ensure that banks remain financially stable and maintain enough liquid assets to handle customer withdrawals and economic uncertainty.
- Maintain Bank Liquidity
SLR ensures that banks always keep a certain portion of their funds in liquid assets like cash, gold, and government securities. This helps banks meet sudden withdrawal demands from customers.
- Control Credit Growth
The Reserve Bank of India uses SLR to regulate how much money banks can lend.
Higher SLR means less money available for loans, while lower SLR means banks can lend more money in the economy. This helps control excessive borrowing and risky lending practices.

- Control Inflation
When inflation rises, the RBI may increase the SLR so banks lend less money into the economy. Reduced lending helps slow down excess spending and inflationary pressure.
- Ensure Financial Stability
SLR acts as a safety cushion for banks during financial stress or economic crises. It reduces the risk of bank failures and strengthens confidence in the banking system.
- Encourage Investment in Government Securities
Since government securities form a major part of SLR assets, banks regularly invest in government bonds and treasury instruments. This supports government borrowing and infrastructure funding.
- Protect Depositors’ Money
By forcing banks to maintain safe liquid reserves, SLR helps protect customer deposits and improves overall trust in the banking sector.
- Prevent Excessive Lending
SLR prevents banks from using all the deposited money for loans. This reduces the chances of liquidity shortages and unstable banking practices.
Uses of Statutory Liquidity Ratio (SLR)
The Statutory Liquidity Ratio (SLR) is used by the Reserve Bank of India as an important banking regulation and monetary policy tool.
- Helps RBI Adjust Banking Reserves
The RBI changes SLR rates depending on economic conditions and reserve requirements in the banking sector.
- Supports Monetary Policy Decisions
SLR works alongside other tools like CRR and repo rate to help the RBI manage money supply and lending conditions in the economy.
- Supports Government Fundraising Activities
Banks invest part of their reserves in approved government instruments, helping the government raise long-term funds.
- Improves Regulatory Monitoring
SLR gives the RBI better oversight of reserve management and banking practices across commercial banks.
- Strengthens Banking Regulation Framework
SLR forms an important part of India’s banking regulation system and helps standardise reserve requirements across commercial banks.

What are the Components of the Statutory Liquidity Ratio
The main components of the Statutory Liquidity Ratio (SLR) are the liquid assets that banks must maintain against their total deposits and liabilities.
1. Cash
This includes the cash reserves available with the bank for immediate use. It helps banks manage sudden withdrawal demands and maintain daily liquidity.
2. Gold
Banks can hold gold as part of their SLR requirement. The gold must be valued according to current market prices approved under banking regulations.

3. Government Securities
This is the largest component of SLR for most banks. It includes:
- Treasury Bills (T-Bills)
- Government bonds
- Dated securities
- State Development Loans (SDLs)
These are considered low-risk investments because they are backed by the government.
4. Approved Securities
Apart from central government securities, certain other RBI-approved financial instruments may also qualify under SLR requirements.
SLR Formula
The Statutory Liquidity Ratio (SLR) formula is used to calculate the percentage of liquid assets a bank maintains against its total deposits and liabilities.
SLR Formula = (Liquid Assets / Net Demand and Time Liabilities (NDTL)) × 100
Here is what each component of the SRF formula signifies-
| Component | Meaning |
| Liquid Assets | Cash, gold, and RBI-approved government securities |
| Net Demand and Time Liabilities (NDTL) | Total deposits and liabilities of the bank |
Example of SLR Calculation
Suppose a bank has:
- Liquid assets worth ₹240 crore
- Net Demand and Time Liabilities (NDTL) of ₹1,200 crore
Now apply the formula:
SLR = (240 / 1200) × 100
SLR = 20%
This means the bank is maintaining a Statutory Liquidity Ratio of 20%.
Difference Between CRR and Statutory Liquidity Ratio (SLR)
Both Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) are important monetary policy tools used by the Reserve Bank of India to regulate liquidity and maintain stability in the banking system. However, they work differently.
| Basis | CRR | SLR |
| Full Form | Cash Reserve Ratio | Statutory Liquidity Ratio |
| Meaning | Percentage of deposits banks must keep as cash with RBI | Percentage of deposits banks must maintain in liquid assets |
| Maintained With | Reserve Bank of India | Bank itself |
| Form of Reserve | Only cash | Cash, gold, and government securities |
| Main Purpose | Control liquidity in the economy | Ensure bank solvency and reserve safety |
| Interest Earned | Banks do not earn interest on CRR | Banks may earn returns on government securities under SLR |
| Impact on Lending | Higher CRR reduces lending capacity | Higher SLR also reduces lending capacity |
| Controlled By | RBI | RBI |
Banking regulations and taxation policies both play an important role in India’s economy. Learn the difference between CGST and SGST and understand how indirect taxes work in the Indian financial system.
If a bank receives ₹1,000 crore in deposits:
- A portion must be kept with the RBI as CRR
- Another portion must be maintained by the bank itself as SLR assets
This ensures that banks do not lend all deposited money and maintain financial discipline.
SLR vs CRR- Which is More Liquid?
CRR is more liquid because it is maintained entirely in cash with the RBI. SLR includes other liquid assets like gold and government securities.
CRR focuses mainly on controlling liquidity in the banking system, while SLR focuses on maintaining bank stability and reserve strength.
