"Today's decision of Ukrainian authorities to nationalize PrivatBank is an important step in their efforts to safeguard financial stability. This decision was taken to ensure the smooth operations of the bank given its systemic role in Ukraine's financial system, and in view of insufficient efforts to strengthen its capital adequacy in recent months," Lagarde said in a statement.

"Ensuring that all banks operating in Ukraine meet capital and regulatory requirements is essential to maintain public confidence in the banking system and reinforce the banks' ability to support productive activities necessary for the prosperity of the Ukrainian people," she stressed.
