Money Market Operations as on September 10, 2026

The Reserve Bank of India's money market operations on September 10, 2026, reveal a sophisticated liquidity management framework that has evolved significantly since the 1991 economic reforms. On this day, the RBI absorbed a massive ₹6,53,116 crore of net liquidity through its Liquidity Adjustment Facility (LAF) operations, demonstrating the central bank's active role in maintaining interest rates within the policy corridor. The LAF, introduced in 2000 based on the Narasimham Committee recommendations, replaced the earlier system of refinance facilities and has since become the primary tool for daily liquidity management. The operations conducted on September 10, 2026, showcase the three-tier LAF corridor structure: the Standing Deposit Facility (SDF) at 5.00% as the floor, the policy repo rate (implied at 5.25% based on the 25 bps spread to SDF), and the Marginal Standing Facility (MSF) at 5.50% as the ceiling. The Variable Rate Reverse Repo (VRRR) at 5.24% cut-off rate, absorbing ₹3,96,694 crore, indicates strong banking system liquidity surplus that the RBI needed to mop up. This is complemented by the SDF absorption of ₹2,56,504 crore at 5.00%, while the minimal MSF borrowing of ₹82 crore at 5.50% suggests no liquidity stress in the system. The overnight money market segment recorded ₹6,76,850.95 crore in total volume at a 4.60% weighted average rate, with Triparty Repo dominating at ₹4,86,883.05 crore (72% of overnight volume). The Triparty Repo system, introduced in 2018 replacing the CBLO (Collateralised Borrowing and Lending Obligation), provides a secured lending platform with CCIL as the central counterparty, reducing counterparty risk. The call money market, traditionally the core of the overnight segment, accounted for only ₹10,335.01 crore (1.5%), reflecting the structural shift toward collateralised lending post-2005 reforms. From a constitutional perspective, the RBI's monetary policy operations derive authority from the RBI Act, 1934, particularly Section 45W which empowers the Bank to regulate money market instruments. The Monetary Policy Framework Agreement (2015) and subsequent amendment to the RBI Act (2016) established the statutory Monetary Policy Committee (MPC) under Section 45ZB, mandating inflation targeting at 4% (±2%). The LAF operations on September 10, 2026, represent the operational implementation of the MPC's policy stance. The significance extends beyond daily liquidity management. Effective transmission of policy rates to money market rates ensures that the RBI's stance — whether accommodative, neutral, or contractionary — reaches the real economy. The fact that the weighted average call rate (4.98%) and Triparty Repo rate (4.65%) trade between the SDF (5.00%) and the VRRR cut-off (5.24%) indicates proper corridor functioning. However, the market repo rate at 4.44% trading below the SDF floor warrants attention, possibly reflecting temporary demand-supply mismatches in specific collateral segments. Looking ahead, the RBI's liquidity management will likely remain active as government spending patterns, foreign portfolio flows, and currency management operations create durable liquidity surpluses or deficits. The introduction of the Standing Deposit Facility in April 2022 (replacing the fixed rate reverse repo) gave the RBI a tool to absorb liquidity without collateral constraints. As India's financial markets deepen, with the Corporate Bond Repo segment still nascent (₹6,413.95 crore overnight), the RBI may encourage broader participation to enhance transmission efficiency. For aspirants, understanding these operations is crucial for grasping how monetary policy translates from MPC decisions to everyday banking rates affecting investment, consumption, and ultimately GDP growth.
