Geopolitics of energy arbitration

International energy arbitration is no longer governed by contract law alone. It is increasingly shaped by geopolitics. Wars now determine far more than energy prices. They influence whether long-term supply contracts remain performable, whether arbitral proceedings can continue, and whether the awards they produce can ultimately be enforced.

The Russia-Ukraine war exposed this transformation. Sanctions fractured contractual performance, complicated enforcement against state entities, and elevated public policy from a peripheral concern to a central feature of international arbitration. The conflict also raised whether awards arising from sanctions-affected contracts can survive review against EU public policy at the enforcement stage. That question is now before the CJEU in Reibel v Stankoimport. The Advocate General's February 2026 opinion confirmed that sanctions-affected disputes remain arbitrable in principle while indicating that EU public policy may nevertheless constrain enforcement. Arbitration's promise of finality is increasingly contingent upon geopolitical realities beyond the tribunal's control.

The Gulf conflict accelerated this shift. Unlike Russia-Ukraine, where disruption was principally regulatory and financial, strikes on Qatar's Ras Laffan LNG complex and Iran's South Pars facilities directly targeted the infrastructure sustaining global energy trade. Combined with instability in the Strait of Hormuz, uncertainty now extends to whether contractual performance remains possible. Energy arbitration now confronts disputes in which commercial obligations, physical disruption and geopolitical conflict have become inseparable.

Force majeure doctrine addresses exceptional interruptions rather than prolonged geopolitical fragmentation. Under English law, relief depends upon establishing that the qualifying event caused non-performance and that reasonable mitigation was undertaken. Those requirements become increasingly contentious where alternative shipping routes exist, substitute supplies remain available at greater cost, or parties invoke force majeure while benefiting from altered market conditions. The inquiry has shifted from whether disruption occurred to whether it genuinely rendered performance impossible.

Yet force majeure represents only one dimension of a broader challenge. The same conflict that obstructs physical delivery may simultaneously trigger sanctions, rendering performance legally impermissible even where it remains commercially feasible. Contractual defences, sanctions and illegality increasingly converge within the same dispute, producing legal uncertainty that existing arbitral jurisprudence was never designed to resolve.

Enforcement presents another challenge. The New York Convention guarantees recognition of arbitral awards in principle, yet sanctions regimes increasingly determine whether that entitlement possesses practical value. Frozen sovereign assets, licensing restrictions and expansive public policy review risk separating legal rights from practical enforceability. The Singapore High Court's decision in DRL v DRK illustrates this. There, a SIAC arbitration was terminated after the tribunal concluded that international sanctions had rendered its continuation impossible under Article 32(2)(c) of the UNCITRAL Model Law, demonstrating that sanctions may prevent proceedings from reaching a determination on the merits.

Generic force majeure clauses are no longer sufficient. Contracts must anticipate the interaction between armed conflict, sanctions, disrupted infrastructure and maritime chokepoints as interconnected legal risks rather than isolated contingencies. Likewise, selecting an arbitral seat requires evaluating not only judicial neutrality and enforceability but also the sanctions exposure of institutions, tribunals and enforcement courts.

The defining challenge of contemporary energy arbitration is no longer determining whether a contract has been breached, but whether arbitration can preserve legal certainty when armed conflict, sanctions and public policy collide. The greatest threat to international energy contracts may no longer be breach itself, but the gradual fragmentation of the legal order that gives those contracts meaning and enforceability.
