For investors trying to understand what statutory liquidity ratio is, it is a reserve requirement set by the Reserve Bank of India (RBI) that requires banks to hold a portion of their liabilities in liquid assets. The SLR full form, or Statutory Liquidity Ratio, reflects the share of a bank’s net demand and time liabilities (NDTL) that must be maintained in assets such as cash, gold and approved securities.
Unlike the Cash Reserve Ratio, which is maintained with the RBI, eligible SLR assets are generally held by banks in the prescribed forms. This requirement can influence lending capacity, support liquidity preparedness and affect broader credit conditions in the economy.
What is statutory liquidity ratio (SLR)?
The SLR full form is Statutory Liquidity Ratio. Under Reserve Bank of India (RBI) directions, banks must maintain a prescribed share of their net demand and time liabilities in India as eligible SLR assets. In simple terms, it is the minimum liquid-asset buffer that banks must maintain in approved forms.
How does the statutory liquidity ratio work?
The statutory liquidity ratio works by requiring banks to hold part of their resources in eligible liquid assets. When a larger share of funds is held in such assets, fewer resources may be available for fresh loans. When the requirement is reduced, banks may have greater room to lend, subject to factors such as credit demand, capital availability and prevailing liquidity conditions.
SLR can therefore influence banking-system liquidity, asset allocation and credit capacity. However, it operates alongside policy rates, the Cash Reserve Ratio, open market operations and other liquidity-management tools.
Under the current RBI framework, commercial banks covered by the applicable directions must maintain SLR assets of at least 18% of their total net demand and time liabilities in India. The requirement must be met at the close of business on every day and is calculated with reference to NDTL on the last day of the second preceding fortnight.

Objectives of the statutory liquidity ratio
The objectives of SLR include:
- Maintaining a liquid-asset buffer to support banks in meeting their obligations
- Moderating the excessive conversion of bank liabilities into loans
- Strengthening liquidity preparedness and balance-sheet discipline
- Supporting monetary and liquidity management by influencing credit availability
- Providing a regulated holding base for approved government securities
These functions arise from the RBI’s reserve framework and the role of SLR as a mandatory liquid-asset requirement. Together, they are intended to support banking-system liquidity, influence lending capacity and contribute to broader financial stability.
Components of the statutory liquidity ratio
The main components of the statutory liquidity ratio are cash, gold and approved securities. Eligible holdings under the applicable RBI directions broadly include:
- Cash or deemed cash: This may include cash in hand, eligible excess balances maintained with the RBI, qualifying current-account balances and balances held under the Standing Deposit Facility.
- Gold: Gold may be included at a value not exceeding its current market price.
- Approved securities: These generally include Government of India dated securities, Treasury Bills, State Government Securities and any other instruments notified by the RBI.
For SLR purposes, approved securities generally need to be unencumbered, which means they should not be subject to a pledge or charge. However, the RBI directions provide certain regulatory exceptions under which specified securities may continue to qualify as SLR assets.
The value and eligibility of these SLR assets are determined according to the applicable RBI computation, valuation and maintenance rules.
What is NDTL in SLR?
NDTL stands for Net Demand and Time Liabilities. It represents certain liabilities that a bank owes to customers, other banks and other entities, after making the adjustments permitted under RBI rules. These may include deposits, borrowings and certain other liabilities.
Demand liabilities are generally payable on demand and may include current-account deposits, the demand portion of savings deposits and demand drafts. Time liabilities are payable after a specified period and may include fixed deposits, recurring deposits and the time-liability portion of savings deposits.
Since SLR is calculated as a percentage of NDTL, a bank’s applicable NDTL forms the base against which its required SLR holdings are determined. A higher NDTL generally results in a higher amount of eligible SLR assets being required, based on the prescribed statutory liquidity ratio.
How is SLR calculated?
The SLR formula used to calculate the Statutory Liquidity Ratio is:
Statutory Liquidity Ratio = (Eligible SLR assets / Net demand and time liabilities) x 100
Eligible SLR assets broadly include qualifying cash, gold and approved securities. Net demand and time liabilities, or NDTL, represent the bank’s relevant demand and time liabilities after applicable inclusions, exclusions and adjustments under RBI rules.
The formula shows the percentage of a bank’s NDTL maintained in eligible SLR holdings. Multiplying the result by 100 expresses the Statutory Liquidity Ratio in percentage terms.
How to calculate SLR with an example?
Consider Ananya, a treasury manager at a commercial bank, who wants to check whether the bank is maintaining the required Statutory Liquidity Ratio. Suppose the bank has:
- Eligible SLR assets: ₹180 crore
- Net demand and time liabilities (NDTL): ₹1,000 crore
Using the SLR formula:
- SLR = (Eligible SLR assets ÷ Net demand and time liabilities) × 100
- SLR = (₹180 crore ÷ ₹1,000 crore) × 100
- SLR = 18%
In this illustrative SLR calculation example, the bank maintains eligible SLR assets equal to 18% of its NDTL. Ananya would compare this calculated ratio with the applicable SLR requirement under the relevant RBI directions to assess compliance. Actual SLR computation is subject to applicable RBI definitions, inclusions, exclusions, valuation rules and regulatory directions.
The figures shown are for illustrative purposes only.
How does SLR affect investors, banks and customers?
For banks, a higher statutory liquidity ratio may reduce funds available for lending and influence asset allocation, loan pricing and portfolio decisions. It also increases the share of funds held in eligible SLR assets, such as government securities.
For customers, changes in bank lending capacity can affect the availability and cost of credit, including loans for homes, vehicles and businesses. Depositors may be indirectly impacted through shifts in liquidity and interest rates, though outcomes also depend on factors like borrower demand, bank capital and credit risk.
For investors, SLR can influence banking liquidity, demand for government securities, bond yields and the transmission of monetary policy. These effects vary based on market conditions and interest-rate expectations.
How does RBI use SLR to manage inflation and economic activity?
An increase in SLR requires banks to hold a larger share of eligible assets, which may reduce their capacity to extend fresh credit and contribute to moderating credit expansion during periods of inflationary pressure. Conversely, a reduction in SLR may increase the funds available for lending during periods of weak economic activity.
However, greater lending capacity does not necessarily result in higher credit availability, borrowing or economic activity. The actual impact depends on factors such as credit demand, banking-system liquidity, bank capital, policy rates and prevailing economic conditions.
In practice, the RBI manages monetary and liquidity conditions using a mix of tools, including policy rates, CRR, liquidity facilities and open market operations. SLR forms one part of this broader regulatory and liquidity-management framework.
What happens if a bank does not maintain the required SLR?
A bank that fails to maintain the required Statutory Liquidity Ratio may be liable to pay penal interest to the Reserve Bank of India under applicable laws and RBI directions. Failure to submit the prescribed SLR return on time may also attract penalties. If a bank persistently fails to maintain the prescribed SLR, the RBI may take further supervisory action, including cancellation of the bank’s licence, where applicable.
How does SLR affect government securities and debt mutual funds?
Changes in SLR may influence bank demand for government securities because approved government securities can form part of eligible SLR holdings.
Other factors remaining unchanged, higher demand may support government-security prices and place downward pressure on bond yields. Lower demand may have the opposite effect. Since debt mutual funds may invest in government securities and other fixed-income instruments, changes in bond prices and yields can affect their net asset values.
Existing debt mutual fund investors may see an increase in NAV when the prices of securities held by a scheme rise, particularly where the portfolio has greater sensitivity to interest-rate movements. However, the extent and direction of any NAV movement depend on the scheme’s portfolio composition, duration, maturity profile and prevailing market conditions. Lower yields may also reduce the potential returns available from new fixed-income investments.
The overall impact depends on interest-rate expectations, inflation, market liquidity and broader RBI policy measures. Mutual fund returns are market-linked and are not guaranteed.
Why is SLR important for banks and the financial system?
SLR creates a mandatory liquidity buffer, supports disciplined asset allocation and limits the extent to which relevant bank liabilities can be deployed as credit. By requiring banks to maintain a portion of their NDTL in eligible liquid assets, it is intended to support liquidity preparedness and contribute to broader financial stability.
Eligible securities may also support access to certain RBI liquidity facilities, subject to applicable rules. However, SLR does not replace capital-adequacy requirements, sound lending practices, asset-quality controls or other liquidity and risk-management standards.
Difference between SLR and cash reserve ratio (CRR)
Although both are RBI reserve requirements linked to NDTL, the difference between SLR and cash reserve ratio (CRR) lies in the form of reserves maintained and where they are held:
| Parameter | SLR | CRR |
| Meaning | Eligible SLR assets maintained against NDTL | Cash reserve maintained with the RBI against NDTL |
| Form of reserve | Qualifying cash, gold and approved securities | Cash only |
| Where held | Generally maintained by the bank in qualifying forms | Maintained with the RBI |
| Income feature | Certain approved securities may earn interest | The RBI does not pay interest on CRR balances |
| Direct effect | Influences asset allocation and lending capacity | Withdraws cash directly from banking-system liquidity |
Conclusion
Understanding what statutory liquidity ratio is helps explain how the RBI links bank liquidity, credit capacity and balance-sheet discipline. SLR affects how banks hold eligible assets, manage lending and meet regulatory requirements, with implications for borrowers, depositors, government securities and bond investors. While the SLR full form is simple, its role extends across liquidity preparedness, banking regulation, approved-security holdings and monetary management.
FAQs
What is the SLR full form?
The SLR full form is Statutory Liquidity Ratio. It is the minimum percentage of a bank’s net demand and time liabilities (NDTL) that must be maintained in eligible SLR assets, such as qualifying cash, gold and approved securities.
How is SLR calculated?
SLR is calculated by dividing a bank’s eligible SLR assets by its net demand and time liabilities (NDTL) and multiplying the result by 100.
SLR = (Eligible SLR assets / NDTL) x 100
For example, if a bank has eligible SLR assets of ₹18 crore and NDTL of ₹100 crore, its Statutory Liquidity Ratio is 18%.
What is the current statutory liquidity ratio in India?
As of July 2026, the current statutory liquidity ratio in India is 18% of NDTL for commercial banks covered by the applicable RBI directions. Banks must maintain the prescribed SLR in eligible assets at the close of business each day. The RBI may revise the rate through regulatory notifications.
Who determines the Statutory Liquidity Ratio?
The Reserve Bank of India determines the Statutory Liquidity Ratio under the applicable banking laws. The RBI specifies the SLR rate, eligible assets, calculation and valuation rules, reporting requirements and consequences of non-compliance. The applicable requirements may differ across categories of banks. Therefore, the latest RBI directions relevant to the bank category should be referred to.
What are the benefits and limitations of the Statutory Liquidity Ratio?
The main benefit of the Statutory Liquidity Ratio is that it requires banks to maintain a minimum liquid-asset buffer. This requirement is intended to support liquidity preparedness, disciplined asset allocation and compliance with regulatory reserve requirements.
However, a higher SLR may reduce the funds available for lending and affect bank margins. SLR also cannot independently address credit risk, poor asset quality, insufficient capital or weak lending practices.
How does the Statutory Liquidity Ratio affect the economy?
The Statutory Liquidity Ratio affects the economy by influencing the funds banks may have available for lending. A higher SLR can restrict lending capacity and credit creation, while a lower SLR can release additional funds that banks may use for lending. However, the actual economic impact depends on credit demand, bank capital, banking-system liquidity, policy rates and other RBI monetary and liquidity-management measures.
