Yes Bank Ltd. sees a credit rating action

The premise needs correction: the Supreme Court did not uphold the write-down. It upheld the Bombay High Court judgment quashing Yes Bank’s March 2020 write-down, thereby reinstating the AT-1 bonds. The hard principal quantum is Rs 8,415 Crores; total liability including accrued interest has been described in media reports as potentially exceeding Rs 13,000–14,000 Crores, but the specific contingent-liability line from the Notes to Accounts could not be confirmed from the cited material. ^[1]

For the latest reported quarter, Q2 FY27 ended September 30, 2026, Yes Bank reported a CET-1 ratio of 13.7%. ^[2] On the bank’s indicative pro-forma assessment, recognising the AT-1 reinstatement would reduce CET-1 to 11.4%, a decline of 2.30 percentage points, or 230 bps. ^[3]

Thus, no contingent liability is being extinguished by the judgment; the judgment creates the requirement to reinstate the AT-1 principal, with the CET-1 effect shown above. The 11.4% figure is indicative and unaudited; it was not reflected in the reported Q2 FY27 CET-1 ratio. ^[3]

Yes Bank’s current position is that coupon discretion remains available under the AT-1 Information Memoranda, but the bank has not yet decided whether to exercise it. Its latest exchange filing says the bank retains the right to exercise coupon discretion, including for the 9% AT-1 bonds whose coupon date was 18 October 2026, and will communicate its decision after completing its legal and regulatory assessment. ^[4]

That discretion is not an unfettered right to withhold coupons. The Supreme Court has directed that the annual coupon payments remain governed by the relevant Information Memoranda and must be paid in accordance with those terms. ^[1] The practical position is therefore:

• The bank continues to assert contractual discretion.
• The court’s ruling does not make the coupon automatically payable irrespective of the instrument terms.
• The bank has not announced a final coupon decision for the affected instruments; the issue remains under assessment. ^[4]

PONV and future capital raising

There is no disclosed change to Yes Bank’s internal PONV policy as a consequence of the judgment. The ruling addressed the legality and authority of the 2020 AT-1 write-off: the judgment identified the relevant write-down routes as an action by Yes Bank under the instrument terms or an action by the RBI, and held that the administrator could not assume the RBI’s regulatory role. ^[1]

PONV is a loss-absorption trigger for AT-1 instruments, not a direct trigger for raising ordinary equity. The stated framework links loss absorption to a CET1 threshold or a determination that the issuer is no longer viable. ^[5] The bank’s current capital-raising discussion is instead being driven by the potential CET1 compression and its growth-capital objectives: management said it would evaluate capital actions, including a possible raise, with reference to regulatory requirements, capital cost and availability, shareholder interests and medium-term growth plans. ^[6]

Implication: the judgment raises the importance of strict compliance with the Information Memoranda, the RBI framework and proper institutional authority when applying any future PONV or write-down mechanism. It does not, based on the bank’s disclosures, create a new PONV trigger or alter the bank’s stated policy for deciding when to raise capital.

The Supreme Court outcome is likely to increase YES Bank’s issuer-specific AT-1 risk premium relative to similarly rated private-sector banks, even if the ruling does not change its formal credit rating. The important correction is that the Court did not uphold the 2020 write-down; it made the opposite outcome final by quashing the write-down and reinstating the AT-1 liability. The bonds carried coupons of 9.5% and 9.0% ^[1].

Why the risk premium should rise

• Legal and resolution risk: The judgment demonstrates that an AT-1 loss-absorption action can be challenged and reversed if the prescribed process is not followed. Investors are therefore likely to demand compensation for issuer-specific legal, documentation and regulatory-process risk.
• Capital-buffer risk: YES Bank’s indicative CET1 ratio fell to 11.4% from 13.7% after recognising the judgment’s effect, while the pro-forma quarterly result swung from a reported profit of Rs 1,080 Crores to a loss of Rs 5,217 Crores ^[3]. Even if the accounting treatment is ultimately adjusted, investors will price the lower effective capital cushion and the possibility of future capital raising.
• Coupon uncertainty: YES Bank retains contractual coupon discretion and had not completed its assessment of whether to exercise it for the 9% AT-1 bonds due on 18 October 2026 ^[4]. That creates a separate payment-risk premium, distinct from principal-loss risk.
• Rating is not the full pricing signal: S&P said it did not expect the judgment to affect YES Bank’s ratings, but still viewed the outcome as earnings-negative because of the 9.0-9.5% coupon burden and uncertainty over intervening coupon payments ^[5]. This implies that investors may price the event through a spread widening even if the rating category remains unchanged.

The finality of the judgment does remove one element of uncertainty—the binary litigation question—but that benefit is likely outweighed initially by the precedent it creates, the reinstated liability, the compressed CET1 position and uncertainty around coupon treatment. The expected effect is therefore a higher spread over the relevant risk-free or swap benchmark, rather than simply a mechanically higher coupon equal to the existing 9.0-9.5% coupons.

Peer spread comparison

Comparable FY26-FY27 AT-1 yield spreads could not be confirmed for the requested private-bank peers:

• RBL Bank: AT-1 yield spread versus similarly rated private-sector banks — N/D — not disclosed.
• IDFC First Bank: N/D — not disclosed.
• IndusInd Bank: N/D — not disclosed.
• Karur Vysya Bank: N/D — not disclosed.
• Bandhan Bank: N/D — not disclosed.

Accordingly, a defensible basis-point estimate of YES Bank’s premium over those banks cannot be calculated. The 9.0% and 9.5% contractual coupons on YES Bank’s legacy bonds are also not directly comparable with current peer yields: they were set when the instruments were issued and are not the same as a current secondary-market yield spread.

Analytical conclusion: absent a directly comparable peer curve, the appropriate conclusion is directional: YES Bank would likely need to offer a wider issuer-specific and legal-resolution premium than a similarly rated bank with an untested AT-1 loss-absorption record. That premium could narrow if the bank clarifies coupon treatment, restores CET1 buffers and demonstrates that future issuance documents provide stronger procedural certainty; it would remain elevated if investors perceive further legal, regulatory or capital-raising uncertainty.
