Role of Reserve Bank of India’s Open Market Operations (OMO) in Managing Liquidity and Inflation in the Indian Economy

SYNOPSIS

When liquidity dries up or floods the system, the RBI uses Open Market Operations to quietly restore balance. By buying and selling government bonds, it manages inflation, stabilizes markets, and keeps credit flowing smoothly through the economy.

When markets tighten or overflow with liquidity, RBI’s Open Market Operations quietly steer the economy toward stability—balancing inflation, credit flow, and growth with precision.

Open Market Operations (OMOs) enable the Reserve Bank of India to manage liquidity, stabilize markets, and control inflation by buying or selling government securities, ensuring balanced credit flow, monetary stability, and sustainable economic growth in India.

As one of the monetary policy instruments to control liquidity, stabilise financial markets, and thereby inflation, OMOs have long served as a significant instrument for the Reserve Bank of India. Open Market Operations (OMOs), the buying and selling of government securities by a central bank, serve as a key instrument through which the RBI regulates money supply and stabilizes the financial system.

Between 2023 and 2025, the role of OMOs expanded significantly as the liquidity position in India was impacted not only by domestic credit demand but also by international capital flows, foreign exchange interventions, and government borrowing. During the first half of 2025, the RBI infused approximately ₹9.5 trillion of durable liquidity into the banking system, out of which nearly ₹5.2 trillion was infused specifically through OMOs. This massive injection of liquidity helped change the liquidity position from a deficit in late 2024 to a surplus position by March 2025.

The central bank has continued to employ open market operations to manage the fluctuating liquidity gaps. In December 2025, it announced the plan to purchase Government of India securities amounting to ₹2 lakh crores in multiple tranchesto ease monetary conditions, promote credit flows, and maintain market stability in view of seasonal withdrawals of funds for activities such as tax payments. Similarly, liquidity injection measures included OMO purchases of approximately ₹1 lakh crores, in addition to forex swaps, to maintain liquidity stability and strengthen monetary policy transmission, even as inflation lowers.

The Reserve Bank of India maintains a distinction between two instruments -The management of durable liquidity via Open Market Operations (OMOs) and the more short-term adjustments through repo and reverse repo transactions under the Liquidity Adjustment Facility (LAF) as LAF instruments deal with short-term shortages to keep the short-term interest rates aligned with the policy repo rate. This distinction allows OMOs to influence medium term inflationary expectations without requiring constant adjustments to interest rates. Open Market Operations (OMOs) play an important role in showing how monetary policy and government borrowing connect with each other. In FY26, OMOs helped the central bank absorbed nearly 47% of the government’s bond issuance program, preventing yields from rising sharply and crowding out private credit, thus keeping liquidity stable even though borrowing had increased and market conditions were tight. The operations also ensured that the cost of funds was under control, thus ensuring that economic growth was promoted without contributing to inflation due to liquidity. Additionally, to ensure that liquidity levels are orderly and that there is a smooth transmission of policy, the central bank has used strategic OMO purchases and swaps to manage seasonal pressures such as advance tax payments, GST, and foreign exchange.

Conclusion:

In conclusion, OMOs have evolved from a supplementary tool into a central pillar of India’s monetary policy framework in an increasingly complex and dynamic financial environment. The operations manage systemic liquidity, stabilize bond markets, and facilitate smooth credit flows, all of which are critical to achieving the dual objectives of growth and price stability. In an environment marked by fiscal expansion, global uncertainty, and changing capital flows. As India navigates fiscal expansion and global financial volatility, the strategic deployment of OMOs will only grow in significance.
