Modernization Of ICC Arbitration: Key Changes In The 2026 ICC Rules Explained

The International Chamber of Commerce ("ICC") has adopted revised Arbitration Rules that will enter into force on 1 June 2026 ("2026 ICC Rules"). The changes mark the largest revision of the ICC Rules since 2012 and introduce a series of targeted reforms aimed at aligning the ICC Rules more closely with the practical realities of modern international arbitration, with a particular focus on cost, speed and procedural efficiency.

Several of the amendments formalize practices that had already emerged in arbitral practice and were reflected in the somewhat dated ICC Note to Parties and Arbitral Tribunals Concerning the Conduct of Arbitrations under the ICC Rules published in 2021 ("ICC Note"). Others are more innovative, most notably the introduction of the Highly Expedited Arbitration Provisions, which contemplate the issuance of a final award within three months of the initial Case Management Conference.
