RBI Absorbs Rs 6.2 Lakh Crore in Liquidity to Anchor Overnight Money Market Rates

The Reserve Bank of India (RBI) drained a net Rs 6,19,975.24 crore (approximately Rs 6.2 lakh crore) of surplus liquidity from the banking system on September 18, 2026, through a combination of same-day and outstanding money market operations.

According to data released by the central bank under press release 2026-2027/1151, total turnover in the overnight money market segment stood at Rs 12,740.38 crore on September 18, with the weighted average rate printing at 5.02 percent. Meanwhile, cash balances held by scheduled commercial banks with the RBI stood at Rs 828,700.80 crore, remaining comfortably above the statutory Cash Reserve Ratio (CRR) requirement.

Multi-Pronged Absorption Strategy

The central bank has deployed both short-term variable rate reverse repo (VRRR) operations and longer-term open market operations (OMO) to manage the massive liquidity overhang sloshing through the Indian financial system:

• VRRR Auctions: On September 18, the RBI conducted a three-day VRRR auction with a notified amount of Rs 2.25 lakh crore, receiving and accepting bids worth Rs 2,22,629 crore (Rs 2.23 lakh crore) at a weighted average rate of 5.24 percent.
• Standing Facilities: Banks continued to park substantial additional surplus balances through the Standing Deposit Facility (SDF) and ongoing repo windows, driving total net absorption past Rs 6.19 lakh crore.
• Durable Liquidity Drainage via OMO: Alongside short-term reverse repo tenders, the RBI initiated open market sales of government securities totaling Rs 1 lakh crore across three tranches. It concluded the first tranche by selling Rs 50,000 crore worth of sovereign papers on September 17, with subsequent tranches of Rs 25,000 crore each scheduled for September 21 and September 28.

Drivers of the Liquidity Surplus

Banking system liquidity has remained in deep surplus over recent weeks, with excess reserves estimated between Rs 6.94 lakh crore and Rs 7.38 lakh crore around mid-September.

The primary catalyst behind the flood of cash was the massive influx from the central bank's special foreign exchange mobilization measures. Inflows generated through Foreign Currency Non-Resident (Bank), or FCNR(B), deposit schemes—which mobilized over $127 billion—were converted via currency swaps with the RBI, releasing enormous rupee liquidity into domestic lenders. Routine government spending, including salary and pension disbursements, further contributed to elevated cash levels.

Market Impact and Investor Implications

With system liquidity excessively loose, the Weighted Average Call Rate (WACR) had slipped to around 5.02%–5.05%, running well below the central bank's policy repo rate of 5.25%.

Key Takeaways for Domestic Investors:

• Short-Term Debt Yields: Aggressive absorption prevents Treasury bill yields and commercial paper rates from collapsing, offering stable returns for liquid funds and ultra-short-duration debt mutual funds.
• Bond Market Sentiment: The RBI's active OMO sales put mild upward pressure on secondary market sovereign yields, particularly in the 5-to-10-year maturity bracket where banks demand higher cut-off yields.
• Credit and Lending Rates: By keeping the overnight call rate aligned with the benchmark repo rate, the RBI ensures monetary conditions remain consistent with its stated policy stance without triggering unintended credit easing.
