The relevant regulatory requirements are set out in a letter dated 02.26.2015, reference № 28-211 / 12780.
As noted in the letter, to prevent the unrestricted outflow of capital abroad, the National Bank of Ukraine (NBU) has the right to demand from the bank copies of additional documentation giving details that the transaction in question has been appropriately registered. It is the case that the designated bank cannot carry out such transactions without confirmation from the NBU.
Every submission of documents by bank clients for foreign currency purchase transactions must contain the appropriate certificate from the SFSU confirming their tax arrears status.
