East-West United Bank (French: Banque Unie Est-Ouest) is a bank based in Luxembourg, established on 12 June 1974 by the Gosbank, the Soviet Union's central bank.[1] It has been fully owned by Russia-based Sistema since 2018.[2] The bank offered private banking[3] and corporate financing.[4] Since the Russian invasion of Ukraine in February 2022 the bank has had to surmount many problems. Unable to sell the business, Sistema took the decision in late 2023 to close the bank.
