AT-1 Bonds: Understanding High Returns and Principal Risks After Yes Bank Case

By Arth Vani Desk · 2026-10-20

Additional Tier-1 (AT-1) bonds, which saw ₹8,400 crore in investor principal written off during the Yes Bank crisis, are a high-risk, high-return fixed-income instrument for banks to raise capital. Indian retail investors considering these bonds must understand their perpetual nature, potential for coupon deferral, and the significant risk of principal write-down.

Key takeaways

Additional Tier-1 (AT-1) bonds, a complex financial instrument, have once again become a topic of discussion among Indian investors, largely due to the precedent set during the Yes Bank crisis. The case highlighted the inherent and significant risks associated with these bonds, particularly the potential for investors to lose their entire principal amount, as seen when a staggering ₹8,400 crore worth of these bonds were written down.

For Indian retail investors, understanding the unique characteristics of AT-1 bonds is crucial before considering them for their portfolio. While they offer attractive high interest rates, they come with a distinct risk profile that is not suitable for everyone.

What are AT-1 Bonds?

AT-1 bonds are a type of perpetual debt instrument issued by banks to strengthen their capital base, specifically their Additional Tier-1 capital. They are considered 'hybrid' instruments because they combine features of both debt and equity. Unlike traditional bonds that have a fixed maturity date, AT-1 bonds are 'perpetual', meaning they do not have a set repayment date. Banks can choose to call them back after a certain period, but they are not obligated to do so.

Why Banks Issue Them

Banks issue AT-1 bonds primarily to meet regulatory capital requirements under Basel III norms. These bonds act as a cushion to absorb losses in times of financial distress before equity capital is completely wiped out. This makes the banking system more resilient. From a bank's perspective, issuing AT-1 bonds can be a cheaper way to raise capital compared to issuing equity, and the interest payments (coupons) are tax-deductible.

How Investors Earn Returns

Investors in AT-1 bonds typically earn returns through attractive, higher interest rates (coupon payments) compared to traditional fixed deposits or even some other corporate bonds. This higher coupon is offered as compensation for the elevated risks associated with these instruments. The interest is usually paid periodically, such as quarterly or semi-annually.

The Yes Bank Precedent and Investor Losses

The Yes Bank restructuring in March 2020 served as a stark reminder of the risks involved. As part of the bank's revival plan, the Reserve Bank of India (RBI) decided to write down (cancel) all outstanding AT-1 bonds, amounting to ₹8,400 crore. This meant that investors, including many retail individuals who had invested directly or through mutual funds, lost their entire principal investment. The decision was controversial but permissible under the terms of the bonds, which allow for such actions if a bank's financial health deteriorates significantly.

Key Risks for Investors

What Investors Should Consider

Given the complexities and risks, AT-1 bonds are generally not suitable for conservative or moderate-risk retail investors. They are best suited for sophisticated investors with a high-risk appetite, who have a thorough understanding of the banking sector and the specific bank's financial health. If considering an investment, it is crucial to:

The Yes Bank episode serves as a powerful lesson that high returns often come hand-in-hand with equally high risks, especially in instruments designed to absorb losses.
