Standing Deposit Facility

1. Meaning and institutional background

The Standing Deposit Facility is an instrument through which the Reserve Bank of India accepts deposits from eligible Liquidity Adjustment Facility participants to absorb surplus funds. It is a standing facility: eligible institutions can access it under the RBI’s prescribed terms rather than wait for a separately announced auction. It is not a deposit scheme for households or ordinary businesses. Its principal purpose is to support monetary-policy implementation by providing an interest-bearing outlet for surplus liquidity.

The Finance Act, 2018 amended the Reserve Bank of India Act, 1934 to enable the RBI to establish this facility. The RBI operationalised it on 8 April 2022. The distinction between legal enablement and operational introduction is important: 2018 created the statutory basis, whereas 2022 marked its actual use as the floor of the monetary-policy corridor.

The Urjit Patel Committee on revising and strengthening the monetary-policy framework, which submitted its report in 2014, had recommended a standing deposit facility. Its introduction addressed a limitation of collateral-backed liquidity absorption: the central bank’s capacity to absorb funds should not depend entirely on how many eligible securities it can offer.

2. How the SDF operates

When a participating bank has surplus funds, it can place them with the RBI under the SDF and earn the applicable interest rate. Funds that could otherwise have been offered in the overnight money market are thereby parked with the central bank. This absorbs liquidity for the deposit’s tenor; it does not permanently extinguish money. On maturity, repayment releases funds back to the participant unless they are absorbed again.

Unlike a reverse repo transaction, an SDF deposit does not involve the RBI supplying government securities as collateral. This is the facility’s defining feature. Under reverse repo, the RBI absorbs funds against securities through a transaction involving their subsequent repurchase. Under the SDF, absorption takes place through a deposit liability of the RBI, without an accompanying securities transaction.

The facility ordinarily absorbs liquidity overnight, although the RBI retains flexibility to absorb liquidity for longer tenors with appropriate pricing when necessary. It is available on all days, including Sundays and holidays, subject to operational rules. Access is available to LAF-eligible participants, including eligible banks and primary dealers, rather than automatically to every financial institution.

An important regulatory distinction concerns reserve requirements. SDF deposits are not eligible balances for maintaining the Cash Reserve Ratio under Section 42 of the RBI Act. However, they are eligible assets for maintaining the Statutory Liquidity Ratio under Section 24 of the Banking Regulation Act, 1949. Thus, earning interest through the SDF does not substitute for maintaining the mandatory CRR balance.

3. Position in the monetary-policy corridor

The Liquidity Adjustment Facility corridor is bounded by a deposit facility below the policy repo rate and a lending facility above it. Since April 2022, the SDF has provided its floor, while the Marginal Standing Facility provides its ceiling. Under the standard symmetric arrangement, the SDF rate is 25 basis points below the repo rate and the MSF rate is 25 basis points above it, creating a corridor 50 basis points wide.

For illustration only, if the repo rate were 6.00 per cent, the corresponding SDF rate would be 5.75 per cent and the MSF rate 6.25 per cent. These are illustrative figures, not a statement of current rates. Aspirants should check the latest RBI monetary-policy resolution because rate levels can change.

The SDF supports a lower bound for overnight interest rates because an eligible bank has the option of earning the SDF rate by depositing with the RBI. It would ordinarily have little incentive to lend comparable overnight funds at a substantially lower return. Nevertheless, this is not an absolute legal minimum for every money-market transaction: differences in access, collateral, market segmentation and operational frictions can produce deviations.

The weighted average call rate is the operating target of monetary policy. The RBI manages liquidity to align this rate with the policy repo rate. The SDF helps prevent surplus liquidity from pushing overnight rates excessively downward, while the MSF provides an upper backstop during shortages. Establishing the SDF did not itself change the inflation target or replace the repo rate as the principal policy signal.

4. Comparison with other RBI instruments

The fixed-rate reverse repo was previously the corridor’s floor. When the SDF was introduced, that floor function shifted to the new facility. However, the fixed-rate reverse repo was retained in the RBI’s toolkit and may be used at its discretion. Therefore, statements that the reverse repo was abolished in April 2022 are incorrect.

Variable Rate Reverse Repo operations also absorb liquidity, but through auctions with rates determined by bidding and acceptance. The SDF instead offers access at an administered rate under standing arrangements. Both may coexist: auction-based operations can manage liquidity for specified tenors, while the standing facility provides a readily available absorption backstop.

The distinction from the MSF is especially important. Under the MSF, eligible banks obtain overnight funds from the RBI against eligible securities, subject to prescribed conditions. Under the SDF, participants place funds with the RBI without receiving securities. Similarly, an outright open market sale absorbs liquidity through the sale of securities, whereas an SDF deposit absorbs funds temporarily without requiring a securities sale.

The SDF also differs from the CRR. CRR is a compulsory reserve requirement, while placement under the SDF is voluntary and interest-bearing. The Market Stabilisation Scheme is another separate mechanism: it absorbs liquidity through government securities issued specifically for sterilisation, with proceeds held in a separate account rather than used for ordinary government expenditure.

5. Significance, limitations and examination relevance

The SDF strengthens the RBI’s ability to handle large liquidity surpluses without being constrained by securities available for collateral-backed absorption. Such surpluses may arise from foreign-exchange purchases, government cash flows or earlier liquidity injections. This makes the instrument useful for both monetary-policy implementation and financial stability, especially when excess liquidity threatens to weaken control over short-term interest rates.

Its effect on inflation is indirect. By influencing liquidity conditions and overnight rates, it contributes to transmission through deposit rates, lending rates, credit conditions and aggregate demand. However, greater SDF usage does not automatically mean that inflation will fall or that bank lending will contract by an equivalent amount. Transmission also depends on credit demand, banking-sector conditions, expectations and the underlying causes of inflation.

The facility is not costless: interest paid on deposits is an expense for the RBI. Nor can it resolve bank insolvency, replace prudential regulation or independently remove supply-side inflation caused by food shortages or imported energy prices. For objective questions, remember the central distinction: SDF means collateral-free absorption, MSF means collateral-backed injection, and reverse repo means collateral-backed absorption.
