Yes Bank stock touches multi-year low after Supreme Court backs AT-1 bond write-off reversal

Yes Bank shares declined 1.15 percent to close at ₹15.43 on October 29, reaching their lowest level since April 2023 and extending total losses for October to 29 percent. This downward movement followed the Supreme Court's decision to uphold the reversal of the lender's ₹8,415 crore additional tier-1 bond write-off, raising market concerns regarding capital adequacy and potential unpaid coupons. Additional tier-1 bonds are high-risk financial instruments that banks issue to bolster their core capital buffers under regulatory norms.

When judicial authorities overturn write-offs that lenders previously relied on to absorb losses, the capital computation changes significantly, creating uncertainty around balance sheet strength and liability payouts. This shifts the risk-reward matrix for equity holders compared to debt holders, altering previous assumptions about capital stability. Investors and financial analysts should review portfolio exposure to banking equities and monitor regulatory capital disclosures closely.

Market participants must track further judicial clarifications regarding coupon payments and debt restructuring impacts on the lender's financial health. Proper evaluation of contingent liabilities protects portfolios against sudden valuation swings in banking stocks.
