RBI sets underwriting auction for ₹32,000 crore G-Secs sale on 7 August 2026
The RBI will conduct an underwriting auction on 7 August 2026 for the Government of India’s ₹32,000 crore re-issue of two securities. The process supports smooth debt market functioning by ensuring firm demand through Primary Dealers’ underwriting commitments.
India’s government securities market will see a key operational milestone on **Friday, 7 August 2026**, as the Reserve Bank of India (RBI) conducts an **underwriting auction** linked to the Government of India’s planned **₹32,000 crore** sale (re-issue) of Government Securities (G-Secs).
The RBI announcement outlines the underwriting commitments of **Primary Dealers (PDs)** under the **extant scheme of underwriting commitment** that has been in place since **14 November 2007**. In practical terms, underwriting helps the auction process run smoothly by ensuring a baseline level of support from PDs, contributing to orderly market development and reliable government borrowing operations.
What is being auctioned: two re-issued G-Secs
As per the RBI communication, the Government of India has announced the sale (re-issue) of the following securities through an auction scheduled for **7 August 2026 (Friday)**:
- **6.36% GS 2031** — **Notified amount: ₹21,000 crore**
- **7.71% GS 2066** — **Notified amount: ₹11,000 crore**
Together, these add up to the **₹32,000 crore** notified amount.
A re-issue means the government is issuing additional amounts of an existing security, which typically supports liquidity by increasing the outstanding stock of that bond in the market. Better liquidity can help market participants—banks, insurers, mutual funds and other investors—trade and price these securities more efficiently.
Underwriting commitments: MUC and ACU requirements for PDs
The underwriting arrangement described by the RBI involves two key components:
1. **Minimum Underwriting Commitment (MUC)**: the minimum amount each Primary Dealer is required to underwrite. 2. **Additional Competitive Underwriting (ACU)**: an auction mechanism where PDs bid competitively, with a **minimum bidding commitment** specified per PD.
For this underwriting auction, the RBI has specified the following per-PD requirements (₹ crore):
- **6.36% GS 2031** (₹21,000 crore notified)
- **7.71% GS 2066** (₹11,000 crore notified)
The underwriting auction will be conducted through a **multiple price-based method**, a standard approach in which accepted bids may carry different prices/terms, reflecting market-based competition.
Timeline, bidding window and settlement of commission
The RBI noted that PDs may submit their bids for the **ACU auction** electronically through the RBI’s **Core Banking Solution (e-Kuber system)** between **09:00 a.m. and 09:30 a.m.** on the day of the underwriting auction.
The communication also clarifies how underwriting compensation will be handled: the **underwriting commission will be credited to the current account of the respective PDs with the RBI on the day of issue of the securities**.
Such operational clarity—on timings, systems and settlement—helps market participants plan participation and supports smoother execution for government borrowing programmes.
**Why it matters:** A well-structured underwriting process strengthens confidence in India’s G-Sec auctions, supporting efficient government financing and deeper bond market liquidity—both essential building blocks for long-term economic stability and investment-led growth.
