RBI to Inject ₹2 Trillion via G-Sec Purchases in 2026

RBI Announces Major Liquidity Infusion

The Reserve Bank of India (RBI) has announced a significant liquidity injection program to manage financial conditions within the banking system. On December 23, 2025, the central bank declared its intention to conduct Open Market Operation (OMO) purchases of Government of India securities (G-Secs) for an aggregate amount of ₹2,00,000 crore, equivalent to ₹2 trillion. This move is designed to provide durable liquidity and ensure stability in the financial markets, particularly in response to anticipated outflows.

The Four-Tranche OMO Plan

The RBI structured the ₹2 trillion liquidity infusion across four equal tranches. Each tranche involves the purchase of G-Secs worth ₹50,000 crore. This systematic approach allows the central bank to manage the liquidity injection in a calibrated manner, responding to evolving market needs. The auctions were scheduled to ensure a steady flow of funds into the system during a period of potential tightness.

Rationale Behind the OMO Purchases

The primary driver for this large-scale OMO program was the need to counteract a liquidity deficit in the banking system. This deficit was largely attributed to significant outflows from banks and companies for advance tax and Goods and Services Tax (GST) payments. Such large, periodic payments can temporarily drain liquidity from the system, putting upward pressure on short-term interest rates. By proactively announcing the OMOs, the RBI aimed to ensure that banks have sufficient funds available for lending and to maintain orderly conditions in the money markets.

Understanding Open Market Operations

Open Market Operations are a core monetary policy tool used by central banks worldwide to regulate the money supply. When the RBI conducts an OMO purchase, it buys government securities from commercial banks in the open market. In exchange for these securities, the RBI credits the banks' accounts with an equivalent amount of money. This process directly increases the cash reserves of the banks, thereby injecting liquidity into the financial system. Conversely, an OMO sale involves the RBI selling securities to absorb excess liquidity.

Details of the First Auction

As scheduled, the first OMO purchase auction for ₹50,000 crore was conducted on December 29, 2025. The RBI purchased a portfolio of seven different government securities with maturities ranging from 2029 to 2053. The central bank successfully injected the targeted amount, although it did not accept any bids for one of the notified securities, the 7.18% GS 2037 bond. This selective approach allows the RBI to influence the yield curve at specific points while achieving its overall liquidity objective.

Broader Context of RBI's Liquidity Management

This OMO program is part of a broader strategy by the RBI to manage liquidity throughout the fiscal year 2025-26. Data indicates that the central bank has been actively using OMOs to absorb a significant portion of the government's borrowing program. By purchasing nearly half of the government securities issued during the fiscal year, the RBI has played a crucial role in preventing excessive hardening of bond yields, which could otherwise result from heavy government borrowing. This intervention helps maintain stable financing costs for both the government and the private sector.

Complementary Liquidity Measures

In addition to the G-Sec purchases, the RBI announced other measures to supplement its liquidity management efforts. A USD/INR Buy/Sell Swap auction for an amount of $10 billion with a three-year tenor was scheduled for January 13, 2026. This tool injects rupee liquidity while also managing foreign exchange market dynamics. Furthermore, the RBI has been using short-term instruments like the Variable Rate Repo (VRR) auctions to manage day-to-day liquidity fluctuations, demonstrating a multi-pronged approach to ensuring financial stability.

Market Impact and Outlook

The RBI's proactive and transparent communication regarding its liquidity operations has been crucial in anchoring market expectations. These measures help cushion the banking system from liquidity tightness, support credit flow to the economy, and strengthen the transmission of monetary policy. By ensuring adequate liquidity, the central bank helps keep overnight money market rates contained and aligned with the policy repo rate. Looking ahead, the RBI has reiterated that it will continue to monitor evolving liquidity and market conditions and stands ready to take appropriate measures to ensure financial stability.
