India's interbank funding market, a crucial component of its financial system, came to a standstill for 90 minutes on Friday, September 4, 2026. This unprecedented freeze was caused by a record liquidity surplus of 9.7 trillion rupees (approximately $102.67 billion) in the banking system, which left banks with no immediate need for short-term borrowing. This surplus liquidity marks an all-time high, surpassing the previous record of 9.2 trillion rupees in September 2021, and complicates the Reserve Bank of India's (RBI) efforts to manage liquidity and overnight rates.
The surge in liquidity is largely attributed to massive inflows from non-resident foreign-currency deposits, specifically the Foreign Currency Non-Resident (Bank) or FCNR(B) scheme. Indian banks raised $127.23 billion through these deposits, which were then largely swapped with the central bank, injecting significant rupee liquidity into the system. The RBI's special forex measures mobilized a total of $136.38 billion by August 31, including FCNR(B) deposits, Overseas Foreign Currency Borrowings (OFCBs), and External Commercial Borrowings (ECBs). The FCNR(B) window, which alone brought in $127.23 billion, closed a month early due to strong responses.
In response to this "problem of plenty," as noted by Nomura economists, the RBI has been actively employing liquidity absorption tools. On September 4, the RBI conducted a variable rate reverse repo (VRRR) auction to mop up surplus liquidity, accepting bids totaling $5.42 trillion at a cut-off rate of 5.24%. This operation aims to keep short-term interest rates aligned with monetary policy objectives and prevent downward pressure on overnight money market rates. Money market experts suggest that the central bank may need to deploy additional tools, such as an incremental cash reserve ratio (ICRR) hike, open market sales, and the market stabilization scheme (MSS) to manage the persistent surplus.
The liquidity surge has created challenges for the RBI in maintaining a balanced financial system. The central bank's special deposit program is estimated to come with a hefty $10.6 billion bill for the RBI, as it shielded banks from currency risk on the raised funds. While some of the current surplus might be offset by increased cash circulation during the upcoming festive season, maturity of forwards, and potential RBI foreign exchange intervention, the record high liquidity necessitates ongoing vigilance and diverse absorption strategies from the central bank to ensure orderly financial market evolution and stable lending rates for borrowers.
