RBI Sets Underwriting for ₹32,000 Crore Bond Auction

The Reserve Bank of India has finalized the underwriting commitment for its upcoming July 10 government securities auction as part of its regular market borrowing program.

MUMBAI – The Reserve Bank of India (RBI) has set the underwriting commitment for its scheduled auction of Government of India dated securities, totaling ₹32,000 crore. As the central bank prepares for the July 10, 2026, sale, it has confirmed the specific underwriting requirements for Primary Dealers to ensure the successful absorption of the re-issued bonds.

The auction includes two major government securities: ₹21,000 crore of the 6.36% Government Security (GS) 2031, maturing on February 16, 2031, and ₹11,000 crore of the 7.71% GS 2066, maturing on May 18, 2066. To guarantee the success of this issuance, the RBI has established mandatory underwriting commitments, requiring Primary Dealers to underwrite ₹5 billion for the 2031 bonds and ₹2.62 billion for the 2066 bonds.

Strengthening Sovereign Debt Stability

The underwriting process is a vital mechanism for the central bank to manage market liquidity and ensure sovereign debt issuance remains stable. By mandating these commitments, the RBI mitigates the risk of undersubscription, particularly in volatile market environments. Primary Dealers are tasked with bidding for the Additional Competitive Underwriting (ACU) portion between 9:00 am and 9:30 am on the auction day to provide the necessary buffer for these securities.

"According to officials at the Reserve Bank of India, the underwriting commitments for the 2031 and 2066 securities are designed to uphold market confidence and ensure the government's borrowing program proceeds efficiently," stated the central bank in its latest notification regarding the auction logistics.

Auction Mechanics and Investor Participation

The sale will be conducted through the RBI's e-Kuber platform using the multiple price method. The government has retained the option to accept an additional subscription of up to ₹2,000 crore against each security if demand exceeds the initial notified amount.

• Retail Participation: Eligible retail investors can participate via the RBI Retail Direct portal, with a minimum bid size of ₹10,000 and multiples thereof.

• Settlement: Successful bidders are required to complete payments by Monday, July 13, 2026.

• Trading: The bonds are already eligible for "When Issued" trading, providing market participants with early price discovery ahead of the formal auction.

Why It Matters

This auction is a cornerstone of the government’s fiscal strategy to finance public expenditure. The presence of robust underwriting commitments signals to domestic and international investors that the sovereign debt market remains well-supported, effectively lowering the risk profile for institutions and retail participants alike. By maintaining a structured approach to these debt auctions, the RBI continues to foster a predictable environment for fiscal management.
