Yes Bank Ltd. sees a credit rating action

Yes Bank’s filing quantified the CET1 hit at approximately 250 bps. Against the reported standalone CET1 ratio of 13.7% for Q2 FY27, that implies a pro forma ratio of roughly 11.2%, although the bank subsequently indicated a more precise estimate of 11.4%, or a 240-bps decline, as of 30 September 2026. The figures remain indicative pending final accounting and regulatory treatment. ^{[1] [2] [3]}

The ruling did not uphold the original write-down; it upheld the judgment setting it aside, requiring reinstatement of the roughly Rs 8,400 crore AT1 principal. ^[1]

No previously earmarked contingent capital buffer is reported as being released. The immediate effect is a reduction in CET1, partly offset by the reinstated AT1 instruments being recognised as AT1 capital. Consequently, the overall Tier 1 and total capital ratios were expected to remain broadly unchanged in the principal-restatement scenario, at around 14% and 15.1%, respectively. ^[4]

The economic effect is therefore a change in capital composition, not a release of surplus capital: the bank loses common-equity loss-absorption capacity while retaining an offsetting AT1 classification. Management was instead evaluating additional capital actions, and any liability for accumulated coupons remained unresolved. ^[3]

Moody’s did not explicitly say that the “legal overhang” has been removed. The latest opinion instead says that the Supreme Court ruling required reinstatement of the AT1 securities, while “it remains unclear whether further legal options are considered by the bank.” ^[5] Moody’s rationale is that the bank can maintain its overall credit profile “despite the decline” in CET1 following the ruling, supported by improving funding, asset quality and profitability. ^[5]

On wholesale funding costs, the disclosed outlook has not materially changed to a lower-cost forecast. Moody’s says Yes Bank’s funding profile has strengthened in recent years, but remains weaker than that of large Indian peers because of its less-established deposit franchise, “and consequently higher funding costs.” ^[5] The opinion provides no quantified post-ruling reduction in wholesale funding spreads or funding-cost guidance.

Implication: the rating affirmation removes an immediate downgrade concern, but it does not amount to a clean declaration that the legal risk or funding penalty has disappeared. Relative to the pre-ruling position, the evidence supports rating stability and continued gradual funding improvement, not a disclosed structural normalization of wholesale funding costs. The remaining constraints are the weaker deposit franchise, the capital hit from AT1 reinstatement and the unresolved treatment of any accrued coupons. ^{[5] [6]}

Verdict: The AT1 litigation leaves Yes Bank with a thinner equity cushion and a more visible dependence on non-equity capital for Tier-1 compliance than its mid-sized peers appear to have on a core-equity basis. The Supreme Court’s reinstatement of the Rs 8,415 Crores AT1 principal preserves Yes Bank’s Tier-1 ratio at roughly 13.70%, but reduces pro-forma CET1 to 11.40% ^{[5] [3]}. The implied AT1 contribution is therefore about 2.30 percentage points, or approximately 16.79% of Tier-1 capital—a derived estimate from those reported ratios.

What the litigation changed

The Supreme Court upheld the reinstatement of the AT1 securities after setting aside the 2020 write-down ^[5]. Economically, this does not bring in fresh equity:

• Yes Bank’s adjusted net worth was reported at Rs 46,970 Crores versus Rs 53,268 Crores before the adjustment, while borrowings would rise to Rs 86,149 Crores from Rs 77,734 Crores ^[1].
• The bank’s total capital adequacy ratio was expected to remain unchanged at 14.50%, because the restored AT1 securities continue to count as regulatory capital ^[1].
• The reported Q2 FY27 figures had not yet booked the litigation impact; the bank was still assessing the accounting treatment, legal options and any accumulated coupon obligation ^{[1] [3]}.

Thus, the resolution protects the headline Tier-1 and total-capital ratios more than it protects common-equity loss-absorbing capacity.

CET1 comparison with peers

The peer comparison is directional: the capital data reports CET1 for each bank, but does not provide a matching total Tier-1 and AT1 split.

Analytical read

• Yes Bank’s regulatory compliance is more instrument-dependent than its CET1 ratio suggests. The bank can retain a Tier-1 ratio near 13.70% only because the reinstated AT1 securities remain eligible for regulatory capital. Without that AT1 component, the pro-forma CET1 ratio would be 11.40% ^{[5] [3]}.
• Most peers have more equity-led capital cushions. RBL, Karur Vysya, Bandhan and IndusInd report CET1 ratios materially above Yes Bank’s 11.40% pro-forma level ^{[7] [9] [10] [11]}. IDFC First is the closest comparison at 13.30% ^[8], but still has a higher reported CET1 ratio.
• The comparison does not prove that peers have no AT1. Their total Tier-1 and AT1 balances are not reported in the cited peer data. The defensible conclusion is narrower: Yes Bank’s core-equity buffer is weaker, and its ability to maintain headline Tier-1 capital is visibly more reliant on AT1 recognition.
• The remaining risk is coupon treatment. If accumulated AT1 coupons are ultimately recognised, Crisil estimated that Yes Bank’s CET1 ratio could fall to around 10.00% ^[4]. That would increase the relative importance of AT1 in the capital stack, subject to the final accounting and regulatory treatment.
