• The Reserve Bank of India (RBI) recently infused over ?25,000 crore into the banking system through a 3-day Variable Rate Repo (VRR) auction, following earlier liquidity injections of around ?3.5 lakh crore via Open Market Operations (OMOs) since January 2026.
• These measures highlight the RBI’s proactive approach to managing short-term liquidity conditions and maintaining monetary stability.

Need for Liquidity Management

Liquidity in the banking system fluctuates due to factors such as tax outflows, government cash balances, and seasonal demand for cash.

A deficit in liquidity can push up short-term interest rates, while surplus liquidity may weaken monetary transmission. Therefore, the RBI actively uses a mix of instruments to ensure that market rates remain aligned with its policy stance.

Variable Rate Repo (VRR): A Market-Based Tool

• The Variable Rate Repo (VRR) is a short-term liquidity injection mechanism under the RBI’s monetary framework. Unlike the fixed repo rate, where the interest rate is predetermined, VRR operates through an auction-based system, allowing the market to determine the borrowing rate.
• Banks bid for funds by offering interest rates, and the RBI allocates liquidity starting from the highest bids until the notified amount is exhausted. Typically, VRR operations are conducted for short durations (1–14 days) against the collateral of government securities.
• This mechanism enables efficient liquidity distribution and real-time price discovery, reflecting actual demand conditions in the market.

Liquidity Adjustment Facility (LAF): Core Framework

• VRR operates within the broader framework of the Liquidity Adjustment Facility (LAF), which is the RBI’s primary tool for managing day-to-day liquidity.
• Introduced in 2000 based on the Narasimham Committee recommendations, LAF allows banks to either borrow from or lend to the RBI.
• The system is structured around a corridor mechanism. At the centre lies the policy repo rate, which signals the monetary policy stance. The upper bound is defined by the Marginal Standing Facility (MSF), while the lower bound is set by the Standing Deposit Facility (SDF), which has replaced the reverse repo as the primary absorption tool.
• The objective is to keep the Weighted Average Call Rate (WACR)—the operating target—closely aligned with the repo rate.

Open Market Operations (OMOs): Quantitative Tool

• In addition to LAF tools, the RBI uses Open Market Operations (OMOs) as a quantitative instrument to manage liquidity.
• OMOs involve the purchase or sale of government securities. When the RBI purchases securities, it injects liquidity into the system; when it sells them, liquidity is absorbed. These operations are conducted through auctions or direct transactions using the RBI’s electronic platform.
• The large-scale OMO purchases in 2026 reflect a systemic liquidity infusion aimed at supporting credit flow and economic activity.

Significance of VRR and Related Instruments

The combined use of VRR, LAF, and OMOs enables the RBI to maintain short-term interest rate stability and effective monetary transmission.

VRR, in particular, provides flexibility by allowing market-driven rate discovery, reducing the need for the central bank to pre-determine liquidity conditions. It also ensures that liquidity mismatches are addressed efficiently without distorting market signals.

Overall, these instruments help in controlling inflation, supporting growth, and maintaining financial stability.
