In a recent liquidity operation, Indian banks parked ₹ 90,931 crore with the Reserve Bank of India (RBI) via a 4-day Variable Rate Reverse Repo (VRR) auction, well short of the notified target of ₹ 1,00,000 crore (i.e. ₹ 1 trillion).
This shortfall highlights evolving dynamics in the banking system’s liquidity, the choices banks make in deploying surplus funds, and the RBI’s delicate balancing act in steering short-term interest rates.
This article explores:
Before delving into the event, it’s useful to recap how these auctions work and why they are critical tools in India’s monetary operations.
Because the return (or cost) is determined by competitive bidding rather than a fixed interest rate, these auctions give the RBI flexibility to fine-tune short-term rates.
In effect, VRR/VRRR are operating under the Liquidity Adjustment Facility (LAF) framework: the RBI ensures that overnight and short-tenor rates evolve within its corridor defined by the Standing Deposit Facility (SDF) rate (floor) and Marginal Standing Facility (MSF) rate (ceiling).
Thus, how banks respond to these auctions is a reflection both of prevailing liquidity dynamics and of their expectations about short-term interest rates or risk.
According to the Business Standard article, banks placed ₹ 90,931 crore in the RBI’s 4-day VRR reverse repo auction, falling short of the notified ₹ 1,00,000 crore target. The auction was conducted under conditions of surplus liquidity in the banking system.
This under-subscription underscores that even when liquidity is ample, banks may hesitate to park all surplus funds with the central bank, preferring alternative avenues or anticipating more profitable short-term opportunities.
Here is a comparative table summarising this and similar auctions to shed light on trends:
Note: Figures are drawn from recent RBI and market news reports; “subscription rate” refers to the proportion of bids submitted relative to notified.
Before this table, we see that banks are cautious in fully committing surplus funds to short-term central bank instruments. After the table, we observe that this pattern points to a delicate interplay of return expectations, alternative liquidity uses, and rate expectations.
By comparing across tenors, the table illustrates how shorter-term auctions tend to see more conservative uptake, even when surpluses are large, reflecting banks’ desire to retain flexibility or chase better yields elsewhere.
In mid-2025, India’s banking system has often been running a liquidity surplus of over ₹ 2.5–3.0 lakh crore. That surplus is driven by a mix of factors: lower credit offtake, government cash inflows, RBI’s open market operations, and a cut in the Cash Reserve Ratio (CRR) which adds durable liquidity.
Given this backdrop, the RBI has started to scale back daily VRR injections (previously used to counter episodes of tightness) and instead lean more on VRRR operations to absorb excess funds.
This shifting mix signals a more nuanced approach—less reliance on blunt daily injections, more on auction-based absorption, and flexible use of durable tools.
Because the objective of absorbing surplus is to avoid short-term rates collapsing below policy thresholds, VRRR auctions push up the cost of parking funds, narrowing the gap between interbank rates and the repo rate.
In recent episodes, weighted average call rates (WACR) and tri-party repo rates have shown upticks following VRRR operations.
However, if banks are cautious or unwilling to commit, under-subscription can limit the efficacy of such operations in anchoring rates. Indeed, some VRRR auctions have seen weak response (e.g. 3-day VRRR with 57,450 crore bids against 1,00,000 crore notified) even in a surplus regime.
In short: VRRR ops help prevent rates from moving too far below the floor, but their impact depends heavily on bank participation.
Banks must decide whether to park surplus funds with the RBI (low risk but possibly lower yield) or deploy them in alternative, riskier short-term instruments (e.g. collateralised markets, interbank loans). The under-subscription suggests many prefer flexibility, anticipating better opportunities or avoiding rigidity.
Additionally, episodes of cash stress (overnight) can discourage banks from over-committing to VRRR auctions. Indeed, Reuters noted that after a sudden spike in overnight rates, banks are likely to be more cautious in future VRRR bids.
Pricing expectations matter: if banks believe short-term yields will rise, they may withhold surplus rather than lock in lower rates via VRRR.
The RBI’s ability to steer short-term rates closer to the repo rate depends critically on auction outcomes. Weak uptake undermines the transmission channel and may force the RBI to lean more on other tools (e.g. overnight windows, durable liquidity adjustments).
Moreover, if VRRR auctions raise the short-term cost of funds, this could partially offset earlier monetary easing steps (e.g. rate cuts or CRR reduction). Analysts have warned that excessive liquidity withdrawal could push money market yields up and soften the impact of the repo rate cuts.
As liquidity is watered down, money market rates and short-term yields may creep upward. That could influence the yield curve, especially at shorter maturities, and raise funding costs for banks and borrowers. Some reports already point to upward movement in T-bill yields by 5–10 bps following surplus withdrawal moves.
However, the impact on longer-term bond markets may be muted if the central bank offsets pressures via OMOs or keeps an accommodative stance elsewhere.
The recent 4-day VRR operation, where banks parked ₹ 90,931 crore (against a ₹ 1,00,000 crore target), is symptomatic of how surplus liquidity and evolving return expectations are reshaping the dynamics of India’s interbank and central banking operations.
Banks are more judicious now in placing surplus funds with the RBI; they weigh the trade-off between the safety and certainty of central bank absorption versus flexibility and yield opportunities elsewhere. The under-subscription underscores this caution.
For the RBI, the challenge lies in orchestrating its liquidity tools, VRRR auctions, CRR adjustments, OMOs, or overnight windows, in a complementary fashion so as to maintain smooth monetary transmission, anchor short-term rates, and avoid volatility.
Looking ahead, success will depend on how well the RBI calibrates the frequency, tenor, and size of VRRR auctions, and whether banks respond credibly. If under-subscription persists, the central bank may have to lean more on overnight tools or durable measures. Conversely, overzealous absorption could lead to inadvertent tightness.
In short, the 4-day auction episode is a microcosm of an evolving liquidity regime, one that’s less about blunt injections or drains, and more about tactical, calibrated operations in an era of persistent surplus.
