SC Upholds Quashing of Yes Bank AT-1 Write-Down: Basel III

🗞️ Why in News The Supreme Court, in a judgment of 15 October 2026 by Justices Dipankar Datta and Augustine George Masih, dismissed the appeals of Yes Bank, the Reserve Bank of India (RBI) and the Union of India. It left standing the Bombay High Court’s judgment that set aside the write-down of Rs 8,415 crore of Yes Bank’s Basel III Additional Tier 1 (AT-1) bonds, holding that the bank’s Administrator had no power to write the bonds down once the Reconstruction Scheme had come into force.

The Case at a Glance

The Court described its reading of the RBI’s Master Circular on Basel III as “possibly, the first of its kind by this Court to date”.

What AT-1 Bonds Are: Basel III Capital in India

Basel III is the capital framework of the Basel Committee on Banking Supervision at the Bank for International Settlements (BIS). The RBI applied it through its Master Circular on Basel III Capital Regulations of 1 July 2015, the version in force in March 2020 and the one the Administrator relied on.

An AT-1 bond is capital that must be able to absorb losses. Annex 16 of the Master Circular gives it two triggers:

Of Yes Bank’s two Basel III series, according to an RBI note quoted in the judgment, the Rs 3,000 crore series allowed write-down and conversion at both triggers, and the Rs 5,415 crore series allowed only write-down. An older Rs 280 crore series of 2013 was not Basel III compliant and was not counted for write-down at all.

March 2020: How the Write-Down Happened

The judgment explains the dropped clause from an RBI note obtained under the Right to Information Act. The note records that “a majority of investors had agreed to conversion of the bonds into equity shares”. The Court found that the proposal to write down or convert the bonds “was abandoned in its entirety at the stage when the scheme was considered by the Central Government”. On why, it was careful: “While it remains a matter of speculation, it appears the intent was to avoid the pending litigation concerning the bonds”.

Why the Write-Down Failed: The Court’s Reasoning

1. The Scheme gave the Administrator no such power. The Court said: “We do not, for a moment, think that the Central Government intended to have the AT-1 Bonds written down”. The Administrator acted under an “erroneous impression or mistaken belief”, and his act was “an impermissible act and ultra vires the Master Circular read with the Reconstruction Scheme”. Reading the power in, it said, would make the Scheme “akin to a half-baked pie, where the last step of the process is left to the Administrator”. A general savings clause in the Scheme “does not, by itself, confer the specific authority to write down the AT-1 Bonds”, because “a power not specifically conferred cannot be implicitly vested through a general, omnibus savings clause”.

2. “Before reconstitution” means before the Scheme takes effect. Clause 2.15 of Annex 16 says that when a bank is reconstituted or amalgamated under section 45, it is deemed non-viable, both triggers are activated, and “the AT1 instruments will be fully converted / written-down permanently before amalgamation / reconstitution”. The Court held that “before” “can only mean before the Reconstruction Scheme takes effect”. “Had the intention been otherwise, the clause ought to have read “before reconstitution is complete”.” Any other reading would leave “investors to wonder at what point the guillotine blade might fall”. The background facts: the Scheme took effect on 13 March 2020; the write-down came on 14 March.

The Lakshmi Vilas Bank contrast. The Court recorded, from a respondent’s counter-affidavit, the context of an earlier case: when Lakshmi Vilas Bank was amalgamated with DBS Bank India, its Basel III compliant Tier 2 bonds of Rs 318.20 crore were written down on 26 November 2020, a day before the amalgamation scheme came into force. Of Yes Bank, the Court said: “Why the same course was not adopted remains unexplained.”

3. The Administrator is not the regulator. An Administrator under section 36ACA “acts as a substitute for the Board of Directors”, and “Any act performed by the administrator beyond the powers clothed upon him would be wholly illegal and void.” Of the two triggers, the first was Yes Bank’s, which it did not use; the second was the RBI’s, which it chose not to exercise. “The Administrator could not have assumed the regulatory role of the RBI”.

4. Necessity does not excuse the manner. The appellants argued that a bail-in (writing down the bonds) and a bail-out (the infusion of funds by the State Bank of India) were both needed to revive the bank. The Court accepted that both may have been needed, but held that “mere necessity cannot possibly circumvent the manner in which the write down ought to have been exercised”.

The Court on the RBI and on Mis-selling

The Court framed the case narrowly: “The question is not whether the AT-1 Bonds could have been or ought to have been written down off. The question is the manner in which it was done”.

It was sharp about the regulator: “The RBI was a mere bystander, allowing the CET1 ratio of YES BANK to drop to an astonishing low of 0.6%”. It added that “to have the investors at the receiving end of the administrative lapses would be highly unfair.”

On who bought the bonds, the Court noted that AT-1 bonds are “high-risk securities and thus, as per the RBI, must be offered only to institutional investors”, yet Yes Bank “actively offered these instruments to individual investors in violation of the Master Circular”. SEBI had penalised a private wealth management firm and the then Managing Director of Yes Bank for facilitating sales to private individual investors.

What the Ruling Does and Does Not Decide

It decides:

• The Administrator’s write-down of 14 March 2020 was without authority, so the Bombay High Court’s order stands.
• “The payment of annual coupon rate shall remain unaffected by the outcome of these appeals and must be made in terms of the Information Memoranda.”

It does not decide:

• That AT-1 bonds can never be written down. The fault lay in the manner, the timing and the authority, not in loss absorption as such.
• Anything beyond these appeals: the Court clarified that its observations “are only for the purpose of decision on these appeals”.

Next steps lie with the bank. In a filing with the stock exchanges on 16 October 2026, Yes Bank said, as The Hindu reported: “The Bank respects the judgment of the Supreme Court. The Bank is examining the judgement in detail including evaluating all available legal options and suitable actions / steps going forward.” It added that it “has access to appropriate capital-management levers”.

Significance: The Mains Angle

• Rule of law in bank resolution. A rescue can impose losses, but only through the power and the procedure the law and the contract lay down. The Court’s test is the manner, not the outcome.
• Certainty for the AT-1 market. Investors price these bonds on knowing when they can be written down. A reading that let the write-down come at any time after reconstruction would, in the Court’s words, leave them to wonder “at what point the guillotine blade might fall”.
• Regulatory accountability. The Court called the RBI “a mere bystander” while CET1 fell to 0.6%. Early supervisory action is cheaper than a late rescue.
• Investor protection. High-risk bonds meant for institutions reached individual investors, which the Court found to be “in violation of the Master Circular”.
• Bail-in versus bail-out. The case shows the tension between asking bondholders to share the loss and keeping a resolution legally clean.

Way Forward

• Write the loss-absorption step into the scheme itself, and complete it before the scheme takes effect, as a respondent’s affidavit on record says was done for Lakshmi Vilas Bank’s bonds.
• Keep the PONV decision with the RBI, recorded and reasoned, since the Court placed it there.
• Enforce the selling rules: AT-1 bonds to institutional investors only, with full risk disclosure.
• Act early on falling capital ratios, so that a bank does not reach a CET1 ratio of 0.6% before anyone steps in.

• The write-down was made by the Administrator, not the RBI or the Central Government; the final Scheme had dropped the write-down clause.
• The Court did not hold that AT-1 bonds can never be written down; it faulted “the manner in which it was done”.
• Per a respondent’s affidavit the Court recorded, Lakshmi Vilas Bank’s Rs 318.20 crore were Tier 2 bonds, written down a day before its amalgamation with DBS Bank India took effect.

Mains, arguments and keywords:

• Keywords: loss absorbency; ultra vires; bail-in versus bail-out; point of non-viability; mis-selling; regulatory accountability.
• Way forward: write any write-down into the scheme before it takes effect; keep PONV with the RBI; sell AT-1 bonds only to institutional investors.

Interview, be ready for:

• “Should bondholders bear losses before taxpayers in a bank rescue?” Accept bail-in in principle, but only through the procedure the contract and the regulator lay down.
