TL;DR: Pari passu - Latin for "on equal footing" - is one of the most consequential two-word phrases in finance law, and its meaning has been litigated all the way to the US Supreme Court. In debt finance, a pari passu clause ensures that a borrower's payment obligations under a bond or loan rank equally with the borrower's other unsecured, unsubordinated obligations of the same class. The clause does not guarantee equal payment; it guarantees equal ranking. That distinction became the center of a decade-long legal battle when Elliott Management's NML Capital fund argued that Argentina's pari passu clause required not just equal ranking but ratable payment - meaning Argentina could not pay restructured bondholders while stiffing holdout creditors. The US Second Circuit agreed, and the resulting injunctions reshaped sovereign debt restructuring globally. In corporate finance, pari passu provisions appear in intercreditor agreements, bond indentures, and loan facilities to establish the relative priority of claims in insolvency. The clause interacts closely with negative pledge provisions (which prevent the borrower from granting security to other creditors without equivalent security) and subordination agreements (which explicitly rank certain claims below others). Getting the pari passu language wrong - or failing to understand its interaction with the debt waterfall - can mean the difference between full recovery and total loss in a restructuring.

What Is a Pari Passu Clause?

A pari passu clause is a contractual provision in a debt instrument (bond, loan agreement, or credit facility) that establishes the ranking of the borrower's or issuer's obligations relative to its other obligations. In its standard form, the clause provides that the obligations under the agreement rank at least equally with all other present and future unsecured and unsubordinated obligations of the borrower, except for obligations that are preferred by mandatory provisions of applicable law (such as statutory priority claims in insolvency, including employee wages, tax obligations, and secured creditors).

The clause operates as a contractual commitment by the borrower not to create a hierarchy among its unsecured creditors outside of what is mandated by law. It does not create security. It does not guarantee payment. It does not establish a lien or charge over assets. What it does is prevent the borrower from voluntarily subordinating the covered obligations to other unsecured obligations through contractual arrangements, corporate actions, or preferential payment practices.

The interpretation of pari passu clauses has generated more legal scholarship and litigation than almost any other standard-form clause in finance. The central question is whether the clause creates a "ranking" obligation (the obligations are equal in the insolvency waterfall) or a "payment" obligation (the borrower must pay all pari passu creditors ratably whenever it makes any payment). The ranking interpretation is the orthodox view supported by most legal scholars and market practitioners. The payment interpretation, adopted by the US courts in NML Capital Ltd v. Republic of Argentina, sent shockwaves through the sovereign debt market and led to significant changes in bond documentation.

Why It Matters

Creditor Protection in Insolvency: The pari passu clause is the unsecured creditor's primary contractual protection against being subordinated to other unsecured creditors. Without it, a borrower could issue new debt that contractually ranks senior to existing obligations, diluting the recovery prospects of earlier creditors in an insolvency scenario.
Sovereign Debt Restructuring: The NML Capital v. Argentina litigation demonstrated that pari passu clauses in sovereign bonds can be used as offensive weapons by holdout creditors to block payments to restructured bondholders. This has transformed sovereign debt restructuring practice and led to widespread adoption of modified pari passu language in new sovereign bond issuances.
Intercreditor Dynamics: In leveraged finance transactions with multiple tranches of debt (senior secured, senior unsecured, mezzanine, subordinated), pari passu provisions establish the ranking within each tranche and interact with intercreditor agreements that govern the relationship between tranches.
Negative Pledge Interaction: Pari passu clauses work in tandem with negative pledge provisions. The pari passu clause ensures equal ranking; the negative pledge prevents the borrower from granting security to other creditors that would give them effective priority. Together, they form the core unsecured creditor protection package.
Documentation Standard: Pari passu clauses are included in virtually every international bond issuance and syndicated loan facility. Their interpretation affects trillions of dollars in outstanding debt obligations. Even minor drafting variations can have significant consequences in a distressed scenario.

Key Elements of a Well-Drafted Pari Passu Clause

Ranking Statement: State that the obligations under the agreement rank and will rank at least pari passu with all other present and future unsecured and unsubordinated obligations of the borrower. The "will rank" language creates a forward-looking commitment, not merely a representation of current status.
Scope of Covered Obligations: Define which obligations are subject to the pari passu commitment. Standard scope covers all payment obligations under the agreement (principal, interest, fees, expenses, indemnities). Address whether contingent obligations (guarantees, indemnification obligations, deferred consideration) are included.
Exceptions for Mandatory Priority: Carve out obligations that are preferred by mandatory provisions of applicable law. In most jurisdictions, statutory priority claims include: secured creditors (to the extent of their collateral), employee wages and benefits, tax obligations, and certain regulatory claims. The carve-out should reference "mandatory provisions of law" rather than listing specific categories, to accommodate jurisdictional variations.
Payment vs. Ranking Clarification (Post-NML Capital): Following the NML Capital litigation, modern pari passu clauses in sovereign and quasi-sovereign bonds increasingly include express language clarifying that the clause establishes ranking parity only and does not require ratable payment. This language was recommended by ICMA (International Capital Market Association) and has become market standard for new sovereign issuances since 2014.
Interaction with Subordination: If the borrower has or may have subordinated debt, the pari passu clause should coordinate with the subordination provisions. The pari passu obligation applies among obligations of the same class (unsecured, unsubordinated); it does not override express subordination arrangements.
Negative Pledge Coordination: The pari passu clause and negative pledge clause should be drafted as complementary provisions. The pari passu clause addresses contractual ranking; the negative pledge addresses the granting of security. Together, they prevent the borrower from elevating other creditors above the covered obligations through either subordination (pari passu protection) or collateralization (negative pledge protection).
Remedies for Breach: Specify the consequences of a breach of the pari passu commitment. Standard remedies include acceleration of the obligations, event of default under the agreement, and cross-default triggers in other agreements. Following NML Capital, consider whether the clause should expressly address or exclude the remedy of specific performance (equitable relief requiring ratable payment).

Market Position & Benchmarks

Where Does Your Clause Fall?

Creditor-Favorable (Broad Pari Passu): Covers all obligations of the borrower (not just payment obligations), includes a ratable payment commitment, no carve-outs beyond mandatory law, cross-default triggered by any breach of pari passu status, specific performance available as a remedy, applies to both direct and indirect obligations (including guarantees issued by the borrower).
Market Standard: Payment obligations rank at least pari passu with all other present and future unsecured and unsubordinated obligations, exception for obligations preferred by mandatory provisions of law, ranking interpretation only (no ratable payment obligation), standard event of default remedies, negative pledge as a separate complementary provision.
Borrower-Favorable (Narrow Pari Passu): Limited to principal and interest obligations only (excluding fees, expenses, and indemnities), broad carve-outs for statutory priority, express statement that the clause does not require ratable payment or equal treatment in any restructuring, waiver of specific performance remedy, pari passu obligation subject to the borrower's right to incur additional indebtedness without restriction.

Market Data

Pari passu clauses are included in virtually 100% of international sovereign bonds, syndicated loan facilities, and investment-grade corporate bond issuances. They are a universal feature of debt documentation.
Following the NML Capital litigation and the 2014 ICMA recommended clause, approximately 85% of new sovereign bond issuances since 2015 have adopted the modified pari passu language that expressly limits the clause to ranking (not payment) obligations.
In leveraged finance, the LMA (Loan Market Association) and LSTA (Loan Syndications and Trading Association) model credit agreements include standard pari passu provisions coordinated with intercreditor agreements and subordination mechanics.
The ICMA's recommended modified pari passu clause (published in 2014) has been adopted by the vast majority of sovereign issuers, including all G20 nations that have issued new international bonds since 2015.
In corporate insolvency proceedings across major jurisdictions, pari passu distribution among unsecured creditors is a statutory principle (e.g., UK Insolvency Act 1986, Section 107; US Bankruptcy Code, Section 726), reinforcing the contractual clause with legislative backing.

Sample Language by Position

Creditor-Favorable: "The Borrower's payment obligations under this Agreement rank and shall at all times rank at least pari passu in priority of payment and in right of payment with all other present and future unsecured and unsubordinated obligations of the Borrower. The Borrower shall not make any payment on account of any other unsecured and unsubordinated obligation unless the Borrower simultaneously makes a ratable payment to the Lenders on the obligations outstanding under this Agreement."

Market Standard (Post-ICMA 2014): "The Notes rank, and will rank, pari passu in right of payment with all other present and future unsecured and unsubordinated External Indebtedness of the Issuer, provided that the Issuer shall have no obligation to effect equal or ratable payment(s) at any time with respect to any such other External Indebtedness, and, in particular, shall have no obligation to pay other External Indebtedness at the same time or as a condition of paying sums due on the Notes, and vice versa."

Borrower-Favorable: "The principal and interest payment obligations of the Borrower under this Agreement constitute direct, unconditional, and unsecured obligations of the Borrower and rank at least pari passu with all other unsecured and unsubordinated obligations of the Borrower, except for obligations mandatorily preferred by operation of applicable law. For the avoidance of doubt, this Section does not require the Borrower to make ratable or proportional payments on all unsecured obligations simultaneously, and the Borrower retains full discretion as to the timing and order of payments on its various obligations, subject to applicable law."

‍

Example Clause Language

Sovereign Bond (ICMA Model): "The Notes constitute direct, general, unconditional, and unsecured obligations of the Issuer which will at all times rank pari passu among themselves and at least equally with all other present and future unsecured and unsubordinated External Indebtedness of the Issuer, save only for such obligations as may be preferred by mandatory provisions of applicable law. For purposes of this provision, 'External Indebtedness' means obligations (other than the Notes) for borrowed money or evidenced by bonds, debentures, notes, or other similar instruments denominated or payable in a currency other than the currency of the Issuer."

Corporate Bond Indenture: "The Notes are senior unsecured obligations of the Company and rank pari passu in right of payment with all existing and future senior unsecured indebtedness of the Company. The Notes are effectively subordinated to all existing and future secured indebtedness of the Company to the extent of the value of the assets securing such indebtedness, and are structurally subordinated to all existing and future indebtedness and other liabilities (including trade payables) of the Company's Subsidiaries."

Syndicated Loan Facility (LMA-Style): "The Borrower shall ensure that at all times the claims of the Finance Parties under the Finance Documents rank at least pari passu with the claims of all its other unsecured and unsubordinated creditors except for obligations mandatorily preferred by law applying to companies generally. The Borrower shall not create or permit to subsist any arrangement under which any of its unsecured and unsubordinated obligations are given contractual priority over the obligations under the Finance Documents."

Common Contract Types

Sovereign Bonds: The most high-profile context for pari passu clauses. Sovereign bonds governed by New York or English law universally include pari passu provisions, and the interpretation of these clauses has defined modern sovereign debt restructuring practice.
Corporate Bond Indentures: Investment-grade and high-yield corporate bonds include pari passu clauses establishing the ranking of the notes relative to other debt obligations of the issuer. The clause is coordinated with the indenture's covenant structure.
Syndicated Loan Facilities: Term loans and revolving credit facilities include pari passu commitments, typically as an information undertaking or a general covenant. The LMA and LSTA model agreements include standard formulations.
Intercreditor Agreements: When a borrower has multiple tranches of debt, the intercreditor agreement establishes the pari passu relationship within each tranche and the subordination relationship between tranches. The intercreditor agreement governs payment waterfall, enforcement rights, and restructuring voting.
Project Finance Agreements: Non-recourse project finance facilities include pari passu provisions among the project lenders, coordinated with the security package and the intercreditor arrangements among senior lenders, mezzanine lenders, and equity providers.
Bilateral Loan Agreements: Even simple bilateral loan agreements between a borrower and a single lender include pari passu provisions to protect against the borrower subsequently issuing senior or secured debt that would subordinate the existing lender's claims.
Guarantee and Indemnity Agreements: Guarantors provide pari passu commitments ensuring that their guarantee obligations rank equally with their other unsecured obligations, preventing the guarantor from subordinating the guarantee to other claims.

Negotiation Playbook

Key Drafting Notes

Choose the ranking interpretation explicitly: Following NML Capital, do not leave the ranking-vs-payment question to judicial interpretation. If you intend a ranking-only obligation (the market standard), include express language stating that the clause does not require ratable or proportional payment. The ICMA 2014 model clause provides widely accepted formulation for this purpose.
Coordinate with the negative pledge: The pari passu clause and negative pledge are complementary protections that should be drafted together. The pari passu clause prevents contractual subordination; the negative pledge prevents security grants that create effective priority. Gaps between the two provisions create exploitable loopholes. For example, a pari passu clause without a negative pledge allows the borrower to grant security to new creditors, giving them effective priority despite nominal pari passu ranking.
Address structural subordination: A pari passu clause at the parent company level does not protect against structural subordination - the risk that subsidiary-level creditors have priority claims on subsidiary assets. If the borrower's assets are held primarily through subsidiaries, the pari passu clause should be supplemented with subsidiary guarantees or asset maintenance covenants.
Define "unsecured and unsubordinated" precisely: The standard pari passu clause ranks the covered obligations equally with other "unsecured and unsubordinated" obligations. Define what constitutes "subordinated" obligations to avoid disputes about whether specific instruments (convertible bonds, junior facilities, shareholder loans) fall within or outside the pari passu class.
Consider the insolvency waterfall: The pari passu clause operates within the framework of applicable insolvency law. Understand the statutory priority scheme in the relevant jurisdiction before negotiating the contractual ranking. Certain claims (employee wages, tax, secured creditors, administrative expenses) will rank ahead of pari passu unsecured claims regardless of the contractual language.

Common Pitfalls

Assuming pari passu means equal payment: The most common misconception. A pari passu clause does not require the borrower to pay all creditors simultaneously or ratably. It establishes equal ranking in the insolvency waterfall. A borrower may choose to pay one pari passu creditor and not another (subject to preference law), without breaching the pari passu clause under the orthodox ranking interpretation.
Ignoring structural subordination: A parent company's pari passu clause is meaningless if the parent has no assets and all value sits in subsidiaries. Subsidiary creditors have direct claims on subsidiary assets; parent-level creditors (including pari passu creditors) have only a residual claim through the parent's equity interest in the subsidiary. Without guarantees or structural protections, the pari passu clause provides ranking equality among an empty class of claims.
Failing to update legacy pari passu language: Pre-2014 sovereign bonds may contain the "old" pari passu language that was interpreted in NML Capital as requiring ratable payment. If you hold or are purchasing legacy sovereign bonds, assess the pari passu language and its litigation exposure. Consent solicitations and exchange offers have been used to update legacy language in many outstanding sovereign bond series.
Overlooking the interaction with acceleration and cross-default: A breach of the pari passu clause typically constitutes an event of default, which may trigger acceleration of the debt and cross-default provisions in other agreements. The cascade effect can turn a technical pari passu breach into a liquidity crisis. Understand the cross-default network before asserting a pari passu breach.
Confusing pari passu with pro rata: In syndicated lending, "pro rata" refers to the lender's proportionate share of the facility commitment. "Pari passu" refers to the ranking of the facility's claims relative to other obligations. Conflating these concepts leads to confusion in payment waterfall provisions and intercreditor arrangements.

Jurisdiction Notes

United States: The US Second Circuit's decision in NML Capital Ltd v. Republic of Argentina (2012, affirmed by the Supreme Court's denial of certiorari in 2014) interpreted Argentina's pari passu clause as requiring ratable payment, and upheld injunctions preventing Argentina from paying restructured bondholders without simultaneously paying holdout creditors in full. This interpretation, while limited to the specific clause language and sovereign context, sent shockwaves through the debt markets. The decision led to Argentina's technical default and ultimately to a $9.3 billion settlement with holdout creditors in 2016. Under the US Bankruptcy Code, the pari passu distribution principle is codified in Section 726 (Chapter 7 liquidation) and applied through the plan confirmation requirements of Chapter 11. New York law governs the vast majority of international sovereign bonds and a substantial portion of corporate bond indentures, making the Second Circuit's jurisprudence particularly influential.

United Kingdom: English law has traditionally interpreted pari passu clauses as ranking-only provisions, not payment obligations. The UK Insolvency Act 1986 (Section 107 for voluntary liquidation, Rule 14.12 of the Insolvency Rules 2016 for compulsory liquidation) establishes the pari passu distribution principle as a mandatory rule of insolvency law. English courts have not adopted the NML Capital payment interpretation, and the prevailing view among English law practitioners is that a pari passu clause establishes ranking equality, not payment equality. The LMA model facility agreements include pari passu provisions that are interpreted under this ranking-only framework. London is a major market for sovereign and corporate bond issuances, and English-law-governed bonds represent a significant portion of outstanding international debt.

European Union and Other Jurisdictions: EU insolvency law (including the EU Insolvency Regulation (Recast) No. 2015/848) recognizes the pari passu principle as a fundamental feature of insolvency proceedings, with each Member State's national law establishing the specific priority waterfall. The EU's framework for sovereign debt restructuring through Collective Action Clauses (CACs), introduced under the ESM Treaty and the Euro Area Model CAC, interacts with pari passu provisions by enabling supermajority restructuring that binds holdout creditors. In Latin America, the NML Capital litigation has had direct effects: Argentina, Brazil, and Mexico have updated their sovereign bond documentation to include modified pari passu language. In Asia, Singapore and Hong Kong follow the English law approach to pari passu interpretation. The IMF has published guidance supporting the ranking interpretation and has endorsed the ICMA model clause as the standard for sovereign debt issuances.

Related Clauses

Negative Pledge - The companion protection to pari passu; prevents the borrower from granting security to other creditors, which would give them effective priority despite nominal pari passu ranking.
Subordination Clause - Establishes a hierarchy among debt obligations, expressly ranking certain claims below others; operates in tension with pari passu provisions by creating the very inequality that pari passu seeks to prevent among same-class creditors.
Cross-Default Clause - A breach of the pari passu commitment may trigger cross-default provisions in other agreements, cascading the consequences across the borrower's debt structure.
Acceleration Clause - Pari passu breaches typically constitute events of default that trigger acceleration rights, allowing creditors to demand immediate repayment of the outstanding principal.
Collective Action Clause - In sovereign bonds, CACs enable supermajority restructuring that modifies pari passu and other terms, binding holdout creditors who might otherwise use pari passu claims to block restructuring.
Intercreditor Agreement - Governs the relationships among creditors holding different tranches of debt, establishing payment waterfalls and enforcement priorities that implement the pari passu principle within and between debt classes.
