RBI VRR auctions: ₹1.25 lakh crore overnight to steady rates

What the RBI is trying to achieve

The Reserve Bank of India will conduct an overnight variable rate repo (VRR) auction worth ₹1,25,000 crore on Thursday to manage evolving liquidity conditions in the banking system. The central bank said the move is aimed at keeping overnight money market rates aligned with the policy repo rate. The weighted average call rate (WACR), which is the operating target for monetary policy, is a key indicator the RBI watches closely. In the latest reported move, WACR inched up to 5.24% from 5.21%, but stayed below the policy repo rate of 5.25%. The RBI’s use of short-tenor liquidity tools signals an attempt to fine-tune conditions without changing the policy stance.

Overnight VRR auction: size and context

The notified size for Thursday’s overnight VRR auction is ₹1,25,000 crore. Overnight VRR operations are typically used for quick liquidity management when the central bank wants to address immediate mismatches in funds availability. The RBI’s communication linked the operation to “evolving liquidity conditions” and the objective of keeping overnight rates close to the repo rate. Such auctions also help absorb transient pressures that can emerge around tax outflows, government cash balances, or uneven distribution of liquidity among banks. The announcement comes even as system liquidity has shown both surplus and deficit readings in recent data points cited by the RBI and news reports.

What happened in the latest five-day VRR auction

Ahead of the overnight operation, the RBI conducted a five-day VRR auction on Wednesday with a notified amount of ₹1,50,000 crore. The central bank received bids worth ₹16,435 crore, far below the notified amount. The bid amount was allotted at a weighted average rate of 5.26%. The low bid participation relative to the notified amount is a useful signal of banks’ near-term demand for central bank liquidity at those rates. It also underlines that notified auction size does not necessarily translate into actual borrowing if banks do not need funds or prefer alternative sources.

System liquidity and the WACR-repo alignment

RBI data showed net liquidity in the banking system was in a surplus of ₹1,50,000 crore on Tuesday. Even with that surplus, WACR moved up to 5.24% from 5.21%, indicating some tightening at the margin while remaining below the 5.25% repo rate. The RBI’s emphasis on keeping overnight rates aligned with the repo rate reflects the operational framework of monetary policy, where the call rate is expected to trade near the policy rate under normal conditions. When the call rate moves persistently above or below the repo rate, the RBI can adjust liquidity through tools such as VRR auctions.

Other VRR operations cited: three-day and seven-day auctions

Separately, the RBI has also announced other VRR operations in recent reports. One update noted a three-day VRR auction worth ₹50,000 crore, with market participants linking the decision to a surge in WACR to 5.31% on a Monday, versus 5.18% at the previous close. In that instance, the call rate was reported to have moved above the repo rate of 5.25%, making liquidity infusion tools more relevant to bring the operating target back in line. Another report described a seven-day VRR auction worth ₹1,00,000 crore scheduled for a Monday, again framed as a response to evolving liquidity conditions.

When liquidity tightened: injections and deficit readings

A separate set of data points highlighted how liquidity conditions can turn quickly. The RBI infused ₹79,256 crore through an overnight VRR auction, with cut-off and weighted average rates of 5.26%. This injection was described as much lower than the notified amount of ₹1,00,000 crore. The same update cited an estimated liquidity deficit of about ₹65,395.64 crore as of March 23, 2026. Another report said the RBI injected ₹48,014 crore via a seven-day VRR auction at a cut-off and weighted average rate of 5.26%, against a notified ₹1,50,000 crore, as surplus liquidity narrowed sharply due to advance tax outflows.

How VRR works and why it is used

VRR auctions allow banks to borrow funds from the RBI against government securities at market-determined rates. Under this mechanism, banks bid based on their liquidity needs, and the borrowing cost is determined by the auction outcome rather than a fixed rate. By varying tenor and notified amounts, the RBI can calibrate short-term liquidity without altering the policy repo rate. The repeated reference to aligning overnight rates with the repo rate suggests the RBI is using VRR as an operational tool to keep the monetary transmission channel functioning smoothly in the money market.

Liquidity toolkit beyond VRR: bonds and FX swaps

In addition to VRR operations, the RBI has outlined the use of multiple instruments to manage liquidity. One plan referenced open market purchases of government bonds, a dollar-rupee buy/sell foreign exchange swap, and a VRR auction. Specifically, the RBI said it would conduct a 90-day VRR operation worth ₹25,000 crore on January 30. It also said it would carry out a three-year USD/INR buy/sell swap amounting to $10 billion on February 4 to inject durable rupee liquidity while managing foreign exchange market conditions. Separately, the RBI said it would purchase ₹1,00,000 crore of government bonds through open market operations in February, split into two tranches.

Market impact and why it matters

The immediate market relevance of these operations is concentrated in overnight and short-tenor rates, especially WACR. With WACR reported at 5.24% against a repo rate of 5.25%, the overnight market is trading close to the policy signal, but small deviations can prompt operational action. The difference between notified amounts and actual bids or injections also matters, because it reflects real demand for RBI liquidity at the prevailing auction rates. Periods of advance tax payments were specifically cited as a driver of tighter liquidity, and the RBI’s use of VRR operations in those periods indicates a preference for temporary, targeted support rather than broad-based measures.

Conclusion

The RBI’s upcoming overnight VRR auction of ₹1,25,000 crore fits into a broader pattern of using variable rate repos to manage short-term liquidity and keep WACR aligned with the 5.25% repo rate. Recent auctions show large notified sizes alongside smaller actual bids or injections, depending on system conditions. Along with VRR, the RBI has also flagged bond purchases and a $10 billion USD/INR swap as part of its liquidity toolkit. The next immediate event for markets is Thursday’s overnight VRR auction outcome, which will indicate near-term demand for RBI liquidity support.
