Supreme Court 2026: Corporate Guarantees Constitute Financial Debt Under the Insolvency and Bankruptcy Code

In State Bank of India and Others v. Doha Bank Q.P.S.C. (2026 INSC 423), decided on 28 April 2026, the Supreme Court of India held that liabilities arising from corporate guarantees squarely fall within the definition of financial debt under Section 5(8) of the Insolvency and Bankruptcy Code, 2016. The judgment, delivered by Justices PS Narasimha and Alok Aradhe, set aside concurrent orders of the National Company Law Tribunal (NCLT) and the National Company Law Appellate Tribunal (NCLAT) that had excluded an SBI-led consortium of banks from the Committee of Creditors (CoC) in the Corporate Insolvency Resolution Process (CIRP) of Reliance Infratel Limited (RITL). The ruling reaffirms the principle that a guarantor's liability is co-extensive with that of the principal borrower and establishes that technical defects in documentation cannot be used to strip lenders of their statutory rights under the IBC.

Background: The Reliance Infratel CIRP and SBI Consortium's Claims

Reliance Infratel Limited (RITL) was admitted into CIRP following a petition filed by its creditors. During the claims process, a consortium of banks led by the State Bank of India, which included Bank of India, UCO Bank, Syndicate Bank, Oriental Bank of Commerce, and Indian Overseas Bank, submitted claims totalling over Rs 3,628 crore. These claims were based on corporate guarantees that RITL had executed to secure credit facilities extended by the consortium to its group entities, Reliance Communications Limited (RCOM) and Reliance Telecom Limited (RTL). Doha Bank, an External Commercial Borrowings (ECB) lender to RITL, challenged the SBI consortium's claims before the NCLT. Doha Bank argued that the corporate guarantees were suspicious in nature, had not been adequately stamped, and were not disclosed in RITL's audited financial statements. Doha Bank further contended that the guarantees were executed without proper board authorisation and were therefore unenforceable. Both the NCLT and the NCLAT upheld these objections, directing the removal of the SBI consortium from the CoC and denying them the status of financial creditors.

Section 5(8) IBC: The Definition of Financial Debt

The Supreme Court's analysis centred on Section 5(8) of the IBC, which defines financial debt as a debt along with interest, if any, that is disbursed against the consideration for the time value of money. Clause (i) of the provision includes within this definition any amount raised pursuant to any note purchase facility or the issue of bonds, notes, debentures, loan stock, or any similar instrument. More critically for this case, the explanation appended to Section 5(8) clarifies that any amount raised from an allottee under a real estate project shall be deemed to be an amount having the commercial effect of a borrowing. The Court emphasised that the language of Section 5(8) is deliberately broad and inclusive. The provision lists various categories of financial transactions that constitute financial debt, and among them is any liability in respect of a guarantee or indemnity for any of the items referred to in the preceding sub-clauses. The Court held that a corporate guarantee, by its very nature, creates a financial liability because it provides a credit enhancement that enables the principal borrower to access funds. The guarantor assumes a contingent liability that crystallises into an actual debt upon the principal borrower's default. This contingent liability has the commercial effect of a borrowing because it is given against the consideration for the time value of money advanced by the lender to the principal borrower.

Rejecting Technical Defences: Stamping, Disclosure, and Board Authorisation

The Supreme Court systematically rejected each of the technical defences raised by Doha Bank and accepted by the lower tribunals. On the stamping issue, the Court held that inadequate stamping renders an instrument inadmissible as evidence until the deficit stamp duty and penalty are paid, but it does not render the underlying transaction void or unenforceable. The remedy for inadequate stamping is the payment of deficit stamp duty, not the nullification of the guarantee itself. On the non-disclosure in financial statements, the Court held that the failure to disclose a corporate guarantee in audited accounts may constitute a violation of accounting standards and disclosure norms, but it does not affect the legal validity or enforceability of the guarantee as between the parties. A guarantee is a contractual obligation that arises from the execution of the guarantee deed, not from its disclosure in financial statements. The accounting treatment is a regulatory compliance matter that is distinct from the contractual enforceability of the instrument. On board authorisation, the Court observed that questions of internal corporate governance and ultra vires acts are matters to be adjudicated in appropriate proceedings, but cannot be used as a sword to defeat the legitimate claims of financial creditors in insolvency proceedings where the objective is maximisation of value for all stakeholders.

Co-Extensive Liability of Guarantor and Principal Borrower

The Court reaffirmed the well-established principle under Section 128 of the Indian Contract Act, 1872, that the liability of the surety is co-extensive with that of the principal debtor unless the contract of guarantee otherwise provides. This means that upon the principal borrower's default, the guarantor becomes liable for the entire debt to the same extent as the principal borrower. The Court clarified that this principle applies with full force in insolvency proceedings. When the principal borrower defaults and the corporate guarantor is subsequently admitted into CIRP, the lender who holds the corporate guarantee is entitled to file a claim as a financial creditor of the guarantor. The debt owed by the guarantor to the lender qualifies as financial debt because it arises from a guarantee given in respect of money borrowed against interest. The Court further held that the financial creditor does not need to first exhaust its remedies against the principal borrower before filing a claim against the guarantor in the guarantor's CIRP. The IBC does not require such sequential enforcement, and imposing such a requirement would defeat the time-bound resolution process mandated by the Code.

Implications for Lenders, Corporate Guarantors, and Insolvency Practice

The judgment strengthens the position of secured lenders who rely on corporate guarantees as part of their credit security package. Banks and financial institutions that hold corporate guarantees can now assert their claims as financial creditors in the CIRP of the guarantor company with greater confidence, knowing that technical objections relating to stamping, accounting disclosure, or alleged procedural irregularities in the execution of the guarantee will not be sufficient to defeat their claims. For corporate debtors and their promoters, the judgment limits the scope for strategic challenges designed to reduce the voting power of secured lenders in the CoC. The reconstitution of the CoC in the Reliance Infratel case, with the SBI consortium restored as financial creditors, will directly affect the outcome of the resolution process and the voting dynamics on any resolution plan. For insolvency professionals and resolution applicants, the judgment clarifies that corporate guarantee claims must be admitted as financial debt and that the guarantee holders are entitled to participate in the CoC with voting rights proportionate to their admitted claims. This ruling provides much-needed certainty in complex group insolvency situations where multiple entities within a corporate group have issued cross-guarantees for each other's borrowings.
