Discuss the role of Variable Rate Reverse Repo (VRRR) auctions in RBI's liquidity management framework. How do surges in capital inflows complicate monetary transmission?

The Liquidity Adjustment Facility (LAF) is the RBI's principal instrument for aligning overnight money-market rates with the policy repo rate. Within it, the VRRR is an auction-based tool that absorbs surplus liquidity for a specified tenor at market-discovered rates [1]. Its growing use reflects a system awash with funds, largely from recent forex inflows.

Role of VRRR in liquidity management

• Rate-corridor discipline: by mopping up surplus, VRRR prevents call and repo rates from sinking towards the floor of the corridor, keeping the operating target near the repo rate [2].
• Price discovery: unlike the fixed-rate window, banks bid competitively; the cut-off signals the true cost of surplus funds — on 3 September 2026 the RBI absorbed over ₹5.18 lakh crore at a cut-off of 5.24% [3].
• Calibration by tenor and quantum: multiple 3-day, 7-day or 14-day auctions with differing notified amounts allow fine-tuning; partial acceptance against notified amounts shows absorption is voluntary, not mandated [1][3].
• Complementarity: VRRR handles short-term surpluses, while OMO sales and CRR changes address durable liquidity — the RBI explicitly uses a mix of instruments [2].

How capital-inflow surges complicate transmission

• Unsterilised rupee injection: dollars purchased or swapped against rupees expand reserve money. The RBI's special USD-INR swap facility (operational 8 June 2026) for FCNR(B) deposits, ECBs and OFCBs [5] drew $136.4 billion by 31 August 2026 [4], flooding banks with rupee funds.
• Weakened signalling: with excess cash, banks price loans and deposits off surplus conditions rather than the policy rate, blunting rate signals [2].
• Impossible trinity: defending the rupee while retaining monetary autonomy under open capital flows forces continuous, costly sterilisation.
• Sterilisation costs and volatility: short-tenor absorption must be rolled over repeatedly, and reversal of flows can swing liquidity sharply.

VRRR thus remains an indispensable stabiliser, but a short-tenor tool cannot alone neutralise durable, externally driven surpluses. Pairing it with OMO sales, longer-tenor absorption and staggered maturity of swap inflows would preserve both exchange-rate stability and effective monetary transmission — the twin objectives of the RBI's flexible inflation-targeting mandate.
