RBI Announces ₹1 Lakh Crore OMO Bond Sales to Mop Up Banking System Liquidity

The Reserve Bank of India (RBI) announced that it will conduct Open Market Operation (OMO) sales of Government of India securities worth an aggregate of ₹1 lakh crore. The open-market sales are aimed at absorbing massive durable liquidity from the banking system after short-term liquidity management measures proved insufficient.

The operations will be conducted in three distinct tranches through multi-security auctions using the multiple-price method:

• Tranche 1 (September 17, 2026): ₹50,000 crore
• Tranche 2 (September 21, 2026): ₹25,000 crore
• Tranche 3 (September 28, 2026): ₹25,000 crore

Liquidity Deluge and VRRR Limitations

The inter-bank liquidity surplus escalated sharply, standing at approximately ₹10.43 lakh crore as of September 10. The liquidity overhang stems primarily from commercial banks mobilising large Foreign Currency Non-Resident (Bank) [FCNR(B)] deposits, which brought substantial foreign exchange into the system. Subsequent dollar-rupee buy/sell swaps with the central bank released equivalent rupee funds to domestic lenders. Additional month-end government expenditure, including salaries and pension disbursements, further elevated the cash balance.

While the central bank deployed Variable Rate Reverse Repo (VRRR) operations, banks displayed a marked reluctance to lock in long-term surplus funds. In a recent 26-day VRRR auction aimed at absorbing ₹5 lakh crore, the RBI received bids worth only ₹60,449 crore. Although a subsequent 4-day VRRR absorbed ₹3.45 lakh crore, it underlined lenders' preference for short-duration instruments over parting with durable liquidity, prompting the central bank to intervene directly through permanent open market bond sales.

RBI Governor Sanjay Malhotra indicated that the central bank was actively reviewing liquidity conditions and noted that multiple tools—including OMO sales and foreign exchange swaps—remained on the table to align money market rates with monetary policy objectives.

Details of the First Auction

For the first ₹50,000 crore auction on September 17, eligible primary dealers and market participants can submit electronic bids on the RBI's E-Kuber platform between 9:30 AM and 10:30 AM.

Bonds Offered in Tranche 1:

• 7.59% GS 2029 (maturing March 20, 2029)
• 6.79% GS 2029 (maturing December 26, 2029)
• 7.61% GS 2030 (maturing May 9, 2030)
• 5.77% GS 2030 (maturing August 3, 2030)
• 6.68% GS 2031 (maturing September 17, 2031)
• 8.28% GS 2032 (maturing February 15, 2032)

The RBI has not set security-specific quotas, retaining the flexibility to accept bids based on market pricing and to alter aggregate accepted sums.

Impact on Bond Yields and Indian Markets

The announcement triggered an immediate repricing across sovereign debt tenors. India's 10-year benchmark government bond yield climbed six basis points to 7.04%, while the 5-year paper rose nearly 10 basis points to 6.62%.

The absorption of ₹1 lakh crore from the inter-bank market will likely establish a floor under short-term money market rates, which had slipped below the benchmark repo rate amid the cash deluge. For fixed-income investors and mutual funds, the resulting steepening of yields offers more attractive entry points in medium-to-long duration sovereign securities, while scheduled commercial banks may see money market borrowing costs firm up over the coming quarter.
