No major procedural or substantive document has been issued in this case to date; this summary is based on a Press Release available in the case file. In Oschadbank v. Russia (II), the claimant, Ukrainian state-owned bank Oschadbank, has initiated a new investment dispute against the Russian Federation. The dispute arises under the Bilateral Investment Treaty between Ukraine and Russia. According to a press release issued by the claimant on July 24, 2025, its legal counsel formally transmitted a Notice of Dispute to Russia on that date. The notice concerns the alleged loss of Oschadbank's substantial assets and operations located in the Donetsk, Luhansk, Kherson, and Zaporizhzhia regions of Ukraine. The claimant asserts that these losses are a result of Russia's actions, which it characterizes as gross violations of Russia's obligations under the investment treaty and general international law. The Notice of Dispute represents the first formal step required under the treaty to commence arbitration. It establishes a six-month cooling-off period, during which the parties may seek an amicable settlement. The claimant has demanded prompt, adequate, and effective compensation for all its losses. Should Russia fail to provide such compensation within the six-month timeframe, Oschadbank has stated its intention to formally commence international arbitration proceedings without further notice. This new proceeding is distinct from a prior arbitration between the same parties, also brought under the Ukraine-Russia BIT. In that earlier case, which concerned losses sustained by Oschadbank following Russia's purported annexation of Crimea in 2014, the claimant obtained a favorable award of USD 1.1 billion. The press release notes that Oschadbank is currently engaged in vigorous efforts to enforce that award against Russian assets globally. The current dispute expands the scope of Oschadbank's claims to encompass its more recent losses in other regions of southern and eastern Ukraine, signaling a continued legal strategy to hold Russia accountable for damages to its investments.
