Yes Bank Shares Crash 20% After Supreme Court Upholds AT1 Bond Write-Down Reversal

The Quick Take

• Yes Bank shares fell 20% to ₹18.15 after the Supreme Court upheld the reversal of the 2020 AT1 bond write-down
• The ruling reinstates ₹8,415 crore in AT1 bonds, creating significant contingent liabilities for the lender
• The verdict revives fundamental questions about Yes Bank's capital structure stability post-rescue

Yes Bank shares collapsed 20% in a single session to ₹18.15 after the Supreme Court upheld the Bombay High Court's 2023 judgment that set aside the write-down of ₹8,415 crore in Additional Tier-1 bonds executed during the bank's 2020 government-backed rescue. The ruling represents a significant legal setback, as AT1 bonds had been written to zero as part of the bailout framework. Reinstating these instruments at face value creates a potential financial liability that the market is now pricing into the bank's equity with urgency.

The verdict reignites questions about Yes Bank's capital structure stability more than six years after its government-orchestrated rescue. AT1 bonds, classified as going-concern capital instruments, are designed to absorb losses at the point of non-viability—but courts have now twice ruled that the regulatory framework used to write them down was improper. For investors, the ruling introduces meaningful uncertainty about the final size of the bank's obligations, with the quantum of interest arrears and legal costs still to be determined.
