Ukraine’s government faces off against oligarch Igor Kolomoisky in a court appeal today over the nationalization of PrivatBank, a case ultimately affecting the country’s ability to get billions in foreign loans. Three years ago, the Poroshenko government seized the nation’s private largest lender as part clean-up of the banking system, arguing that bad practices drove the bank to insolvency. Earlier this year, a Kyiv court ruled the nationalization illegal. The case is a test of President Zelenskiy’s political will to fight powerful vested interests.
