Overview
On May 21, 2026, the Astana International Financial Centre Court in Kazakhstan authorized the enforcement of a $1.4 billion international arbitration award against Russia's Gazprom in favor of Ukraine's Naftogaz. The case stems from a Swiss arbitration ruling over an unfulfilled five-year gas transit contract between Gazprom and Naftogaz, with the enforcement permitted on Kazakh territory after Gazprom did not comply with the award voluntarily.
What Happened
The Astana International Financial Centre Court ruled to permit enforcement in Kazakhstan of an international arbitration award requiring Gazprom to pay $1.4 billion to Naftogaz.
A Swiss arbitration court originally issued the award in June 2025 in favor of Naftogaz, following a dispute over a 2019 gas transit contract intended to ship Russian gas through Ukraine to Europe.
After the start of the Russia-Ukraine war, gas flows through Ukraine decreased and Gazprom made payments only for actual volumes delivered, contrary to the contract's requirements. Naftogaz initiated arbitration over this contract breach.
Gazprom challenged the Swiss award, but Switzerland's Federal Supreme Court upheld it, ordering Gazprom to pay $1.37 billion including interest and legal costs. The amount was reported to have risen further due to ongoing interest and expenses.
Kazakhstan's court is the first foreign court to authorize enforcement of this Swiss arbitral award, according to Naftogaz. Gazprom had not commented on the ruling at the time of reporting.
Context
The Ukraine-Russia gas transit arrangement signed in 2019 required Gazprom to pay for transit capacity regardless of the actual volume delivered. After war disrupted shipments, the payment arrangement became a source of dispute.
Naftogaz began legal efforts to recover the award internationally, given Gazprom's non-compliance, and the enforcement in Kazakhstan marks an initial step in that process outside Switzerland.
Why It Matters
- This ruling allows Naftogaz to seek Gazprom assets in Kazakhstan to satisfy the unpaid arbitration award.
- It demonstrates courts in third-party jurisdictions permitting enforcement of arbitral awards tied to major international energy contracts.
- The decision may have implications for other efforts by Naftogaz or similar claimants to enforce arbitration awards against non-compliant state-owned entities.
