Abstract

This paper examines the ISDA Master Agreement not merely as a contractual template but as a normative instrument with profound implications for global financial markets. It interrogates the ways in which repeated adoption, judicial recognition, and regulatory reliance converge to produce a framework that functions in many respects like law, even if it is not formal sovereign law. By situating the Master Agreement at the intersection of customary international law, transnational private law, and contract-as-law theory, the study aims to illuminate how private contracts can generate systemic authority, influence market behavior, and establish normative expectations that extend beyond the parties themselves.

The research explores the practical mechanisms through which ISDA operates. Credit support annexes, confirmations, and collateral arrangements translate abstract contractual obligations into enforceable outcomes. Judicial decisions, particularly in English and United States courts, provide reinforcement by interpreting and upholding ISDA clauses across disputes involving bankruptcy, netting, and cross-border enforcement. Regulatory actors, including central banks and international standard-setting bodies, rely on the framework to measure counterparty risk and maintain financial stability. Taken together, these interventions create a self-reinforcing normative cycle that parallels many functions traditionally associated with law.

Critics of the ISDA framework argue that its dominance grants disproportionate authority to private financial actors, raising questions about accountability and systemic risk. This paper engages with such critiques while emphasizing the practical necessity of ISDA in stabilizing otherwise fragmented and volatile derivatives markets. It interrogates the tension between private contractual authority and public regulatory oversight, illustrating how repeated practice and tacit recognition can produce normative force even in the absence of formal legislative enactment.

The theoretical contribution of this study is significant. Customary international law explains how repeated conduct combined with state recognition can produce binding norms. Transnational private law demonstrates that non-state actors can generate rules with systemic effect. Contract-as-law theory highlights how widely adopted contractual frameworks can function as constitutive instruments for markets, allocating risk, guiding behavior, and influencing judicial interpretation. Each lens alone offers insight, but together they provide a comprehensive explanation for the normative power of ISDA and its quasi-legal function.

In conclusion, this paper argues that the ISDA Master Agreement occupies a liminal space between private and public authority, contractual form and law-like function. Its study reveals broader truths about the evolving nature of authority in global finance, the role of private contracts in shaping market norms, and the complex interplay between repeated practice, judicial recognition, and regulatory reliance. By analyzing ISDA through multiple theoretical perspectives and grounding the discussion in judicial and practical realities, the paper contributes to an enriched understanding of how private agreements can achieve normative force on a global scale, challenging traditional doctrinal assumptions about the origin and enforcement of law.
