What is the controversy around AT1 Bonds?

Additional Tier 1 (AT1) bonds, also known as perpetual bonds, are hybrid instruments issued by banks to strengthen their capital base under Reserve Bank of India regulations aligned with Basel III norms. They offer higher interest rates than traditional bonds but come with unique risks: no fixed maturity, discretionary interest payments, and the possibility of write-down or conversion into equity during financial stress.

In India, AT1 bonds have come under scrutiny following past episodes like the Yes Bank crisis, where such bonds were written down entirely, wiping out investor wealth. More recently, concerns have resurfaced around HDFC Bank, not due to immediate financial distress, but because of regulatory tightening and evolving investor awareness.

The “storm” stems from a mix of factors: stricter risk perception post-Yes Bank, increased retail participation in complex instruments, and ongoing discussions by the Securities and Exchange Board of India on improving disclosure and suitability norms. For HDFC Bank, one of India’s most stable lenders, the debate is less about solvency and more about transparency, pricing, and investor protection.

AT1 bonds remain crucial for bank capitalisation, but the recent spotlight highlights a broader lesson: higher returns often come with hidden structural risks that investors must fully understand before participating.
