SLR

1. Meaning, legal basis and institutional purpose

SLR requires banks to maintain a prescribed stock of liquid assets against their net demand and time liabilities, or NDTL. Its principal legal foundation is Section 24 of the Banking Regulation Act, 1949. RBI directions specify the applicable ratio, eligible assets, valuation rules and reporting requirements. The statutory requirement is expressed with reference to liabilities in India, and qualifying assets must be maintained in India.

SLR serves both prudential and monetary purposes. A liquid-asset buffer improves a bank’s ability to meet its obligations without relying entirely on fresh borrowing or the hurried sale of illiquid loans. By influencing how much of a bank’s balance sheet must be allocated to eligible assets, SLR also affects the resources available for ordinary lending. Historically, high SLR requirements helped channel substantial bank resources into government securities.

However, SLR is not a guarantee against bank failure. Securities may face market-price risk, and a bank can remain vulnerable to credit losses, concentrated funding or sudden withdrawals despite meeting the ratio. Under India’s contemporary monetary framework, the policy repo rate and liquidity-management operations have a more immediate role in monetary transmission. SLR remains important but is not the RBI’s routinely adjusted policy signal.

• Do not confuse the legal maximum of 40% with the operational ratio prescribed by the RBI.
• Removal of the statutory minimum gave the RBI flexibility to prescribe SLR below 25%.

2. Calculation, eligible assets and compliance

Conceptually, SLR equals the value of eligible liquid assets divided by the relevant NDTL, multiplied by 100. Demand liabilities are payable on demand, such as current-account balances. Time liabilities are payable otherwise than on demand, such as fixed deposits. Savings-bank deposits contain demand and time components for regulatory classification. NDTL is therefore a defined regulatory measure, not merely the sum of all customer deposits appearing on a balance sheet.

Netting is particularly relevant to liabilities and assets within the banking system. The treatment of interbank positions, other liabilities and specific exclusions follows RBI rules. For maintenance purposes, banks use the prescribed reference-date NDTL, generally that of the last Friday of the second preceding fortnight. The balance-sheet base and the date on which the asset requirement is observed should therefore not be assumed to be identical.

Eligible assets include cash, gold and unencumbered approved securities. In practice, eligible government securities are central to SLR portfolios. These include Treasury Bills, Central Government dated securities and State Government securities that qualify under the applicable rules. Ordinary corporate bonds, equities, real estate and loans do not become SLR assets simply because a bank considers them valuable or readily saleable.

Unencumbered broadly means that assets are not subject to restrictions preventing their use, although RBI directions provide specific treatments and exceptions. Assets must also be valued under prescribed rules: a rise or fall in security prices can affect regulatory calculations. Cash maintained to meet CRR cannot simply be counted again towards SLR; the treatment of cash balances and any eligible excess is governed by the relevant directions.

• Illustration: at an SLR of 18%, relevant NDTL of ₹1,000 crore requires at least ₹180 crore in eligible assets.
• A bank may voluntarily hold more than the minimum; excess SLR holdings are not a regulatory violation.
• Non-compliance can attract penal interest and other supervisory action.

3. How SLR changes influence credit and monetary conditions

An increase in SLR requires a bank operating near the minimum to allocate more resources to eligible assets. Other things remaining equal, this reduces the balance-sheet space available for ordinary loans. Conversely, an SLR reduction relaxes that constraint and may allow a bank to expand lending or change its investment mix. These are directional effects, not mechanical predictions of the final outcome.

Consider a bank with relevant NDTL of ₹1,000 crore. Reducing SLR from 19% to 18% lowers its minimum eligible-asset requirement by ₹10 crore. This does not mean that the RBI transfers ₹10 crore to the bank. Rather, the bank gains regulatory flexibility. It may sell securities, refrain from replacing maturing securities, or continue holding them if lending opportunities are unattractive.

Actual credit expansion depends on borrower demand, creditworthiness, bank capital, funding costs and the bank’s willingness to accept risk. If a bank already holds SLR assets substantially above the required minimum, a reduction may have little immediate effect. Nor does a lower SLR automatically compel banks to reduce lending rates. Interest-rate transmission operates through several channels, including deposit rates, market yields and competition.

SLR also affects the government-securities market. A mandatory holding requirement creates structural demand for eligible securities and can support government borrowing. Excessively high requirements, however, may crowd out private-sector credit or create financial repression when combined with administered returns. Eligible securities can also support collateralised borrowing, subject to operational rules, so their liquidity value should not be confused with that of funds permanently immobilised.

• Higher SLR: a potentially tighter lending constraint, especially for banks close to the minimum.
• Lower SLR: greater lending flexibility, not guaranteed lending growth or an equivalent increase in money supply.

4. Distinguishing SLR from related requirements

CRR and SLR both link reserve requirements to bank liabilities, but their asset composition and location differ. For scheduled banks, CRR is maintained as cash balances with the RBI under Section 42 of the RBI Act, 1934. SLR is maintained by banks in eligible assets under the Banking Regulation Act. Government securities held for SLR generally earn interest; CRR balances do not earn interest under the prevailing framework.

The Liquidity Coverage Ratio, or LCR, is a Basel III liquidity standard. It requires sufficient high-quality liquid assets to meet projected net cash outflows over a 30-calendar-day stress period. SLR uses NDTL as its base, whereas LCR uses stressed net cash outflows. Some government-security holdings can support both requirements under RBI rules, including specified regulatory carve-outs, but the two ratios are not interchangeable.

Capital adequacy addresses loss absorption rather than the availability of liquid assets. It compares regulatory capital with risk-weighted assets. A bank can satisfy SLR yet lack adequate capital to expand lending. Similarly, repo operations involve collateralised borrowing or lending of funds; SLR is a continuing balance-sheet requirement. These distinctions frequently determine the correct answer in statement-based prelims questions.

• Liquidity concerns meeting payment obligations; solvency concerns whether losses can be absorbed without exhausting capital.
• Neither SLR compliance nor ownership of government securities eliminates interest-rate risk.

5. Reform trajectory and examination relevance

Before financial-sector liberalisation, India combined high statutory pre-emption of bank resources with extensive administered financial controls. SLR reached 38.5% in 1990. The 1991 Narasimham Committee recommended reducing statutory pre-emption and moving towards a more market-oriented financial system. Subsequent reductions in SLR helped give banks greater discretion over their deployment of funds.

In December 2018, the RBI announced a calibrated reduction from 19.5%, in quarterly steps of 25 basis points beginning in January 2019, until SLR reached 18% in April 2020. The announced objective included aligning SLR with LCR requirements. This sequence is important: the final reduction in April 2020 was part of an earlier announced schedule, rather than a measure first designed in response to COVID-19.

For prelims, focus on the legal basis, eligible assets, denominator and likely direction of effects. Be cautious with absolute statements such as 'all SLR assets earn interest', 'SLR is deposited entirely with the RBI', or 'a reduction necessarily increases lending'. For analytical answers, present SLR as a balance between liquidity resilience, efficient credit allocation and the broader development of financial markets.

• One basis point is 0.01 percentage point; 25 basis points equal 0.25 percentage point.
• Always attach an effective date to a quoted operational SLR rate.
