Govt to conduct ₹30,000 crore G-Sec switch auction to optimise debt profile

The Government of India has announced a conversion/switch of its securities through an auction for an aggregate amount of **₹30,000 crore (face value)**, as per an RBI press release. The operation will be conducted on **Monday, 17 August 2026**, with settlement scheduled for **Tuesday, 18 August 2026**.

A switch (or conversion) auction allows market participants to exchange (“switch”) holdings of one set of Government of India securities (the **source securities**) into another set (the **destination securities**). Such operations are commonly used to manage the government’s redemption profile, support orderly market functioning, and improve the overall efficiency of public debt management.

What has been announced According to the notified plan, the auction will cover multiple source securities—largely maturing in **2027–2030**—and offer corresponding destination securities with longer maturities, extending up to **2060**.

The security-wise switch details (face value) are:

• **₹2,000 crore**: 8.26% GS 2027 (maturing 02 Aug 2027) → 7.19% GS 2060 (maturing 15 Sep 2060)
• **₹3,000 crore**: 7.17% GS 2028 (maturing 08 Jan 2028) → 6.64% GS 2035 (maturing 16 Jun 2035)

• **₹3,000 crore**: 7.26% GS 2029 (maturing 14 Jan 2029) → 6.64% GS 2035 (maturing 16 Jun 2035)

• **₹5,000 crore**: 7.10% GS 2029 (maturing 18 Apr 2029) → 7.62% GS 2039 (maturing 15 Sep 2039)
• **₹2,000 crore**: 6.45% GS 2029 (maturing 07 Oct 2029) → 7.10% GS 2034 (maturing 08 Apr 2034)
• **₹5,000 crore**: 7.88% GS 2030 (maturing 19 Mar 2030) → 6.67% GS 2035 (maturing 15 Dec 2035)

Together, these add up to the notified **₹30,000 crore**.

How the auction will work Market participants will place bids on the RBI’s **Core Banking Solution (e-Kuber)** platform. Bids must specify the amount of the source security being offered and the prices of both the source and destination securities, expressed in **Indian Rupees up to two decimal places**.

The auction will follow a **multiple-price** format—meaning successful bids may be accepted at the **respective quoted prices** offered by each bidder, rather than at a single uniform price.

Key timings and milestones:

• **Bid window:** 10:30 AM to 11:30 AM on **17 August 2026 (Monday)**
• **Results announcement:** on the **same day**
• **Settlement:** **18 August 2026 (Tuesday)**

The announcement also notes that the **Government of India reserves the right** to accept offers for less than the notified amount and may also purchase marginally higher than the notified amount, as permitted under the stated framework.

A constructive step for orderly debt management Switch operations are generally viewed as a practical tool for **smoothing near-term maturities** and reducing concentrated redemption pressures in specific years. By offering longer-dated destination securities, the government can spread repayments over time, which supports predictability in borrowing and helps keep the market in a steady rhythm.

For investors, the exercise provides an avenue to **rebalance portfolio duration**—for example, moving from shorter maturities to longer ones—through a transparent auction process. For the broader market, such operations can improve **liquidity** in key benchmark securities and aid in building more actively traded segments along the yield curve.

**Why it matters:** A well-executed G-Sec switch programme helps India manage its debt maturity profile smoothly, supports market liquidity, and strengthens confidence in a transparent, rule-based government securities market.
