RBI Concludes Rs 1 Lakh Crore Liquidity Drain with Rs 25,000 Crore OMO Bond Sale Auction

The Reserve Bank of India (RBI) concluded the final leg of its targeted liquidity absorption program on September 28, successfully selling government securities worth Rs 25,000 crore through an Open Market Operation (OMO) sale auction. With this auction, the central bank fulfilled its planned Rs 1,00,000 crore bond sale program announced earlier in September to withdraw structural surplus liquidity from the domestic banking system.

The auction drew robust participation across six sovereign papers maturing between 2029 and 2032, with the central bank allocating the majority of the issuance to longer-duration paper.

Breakdown of the September 28 Auction

The central bank accepted bids across all six offered securities without setting specific notified amounts for individual bonds, exercising its discretion on allocation:

Accepted Bids and Yield Levels:

• 6.54% GS 2032: The central bank accepted the largest share at Rs 14,350 crore, setting a cut-off price of Rs 97.63 and a cut-off yield of 7.0810%.
• 7.26% GS 2032: Accepted bids totaled Rs 6,450 crore at a cut-off price of Rs 100.74, translating to a cut-off yield of 7.1021%.
• 7.61% GS 2030: Accepted volume stood at Rs 1,350 crore with a cut-off price of Rs 102.19 and a cut-off yield of 6.9108%.
• 5.85% GS 2030: Allotments reached Rs 1,320 crore at a cut-off price of Rs 96.07, yielding 6.9481%.
• 7.59% GS 2029: Accepted bids reached Rs 920 crore at a cut-off price of Rs 102.07 and a yield of 6.6676%.
• 6.45% GS 2029: The smallest tranche was accepted at Rs 610 crore with a cut-off price of Rs 99.27 and a cut-off yield of 6.7201%.

Together, the two 2032-maturing bonds absorbed Rs 20,800 crore, accounting for more than 83% of the total auction size. Settlement of the auction occurs through the participants' current accounts on September 29.

Completion of the Rs 1 Lakh Crore OMO Roadmap

The September 28 auction marks the third and concluding phase of the OMO sales initiative outlined in the RBI’s September 11 notification.

The central bank conducted the program in three structured tranches:

• Tranche 1 (September 17): Rs 50,000 crore absorbed.
• Tranche 2 (September 21): Rs 25,000 crore absorbed, following total bids worth over Rs 84,000 crore.
• Tranche 3 (September 28): Rs 25,000 crore absorbed.

By completing all three tranches, the RBI has drawn exactly Rs 1,00,000 crore directly out of the banking system via primary secondary-market sales.

Drivers Behind the Liquidity Withdrawal

The RBI’s aggressive OMO intervention has been primarily necessitated by persistent, high liquidity surpluses within the Indian banking system, which had climbed above Rs 6 lakh crore in mid-September.

The build-up was propelled by heavy mobilization of foreign currency funds, notably via the RBI's special USD-INR swap window, where inflows exceeded $143 billion, including over $132.9 billion mobilized through Foreign Currency Non-Resident (Bank), or FCNR(B), deposits. As commercial lenders swapped foreign exchange for Indian rupees with the central bank, systemic rupee liquidity expanded sharply. Seasonal government spending on pensions and salaries further widened this surplus.

Market Implications for Investors and Borrowers

By conducting outright sales of government securities, the central bank permanently absorbs rupee liquidity, requiring purchasing institutions to remit cash directly to the RBI.

For Indian debt markets, concentrating the auction allotment in 2032 maturities places a slight upward floor on benchmark 7- to 8-year sovereign yields, helping align overnight money market rates with the prevailing policy repo rate. Investors in fixed-income securities and bank treasury desks can expect money market conditions to remain closely calibrated, limiting excess credit creation while keeping bond yields steady across the middle of the sovereign yield curve.
