If such an agreement does not set the interest rate, the bank must pay interest at the rate of rate of the National Bank of Ukraine (part 1 of article. 1061 CC Ukraine, 3.4 Resolution of the Board of the National Bank of Ukraine from December 3, 2003 516 "On Approval of Regulation on the implementation of the Ukrainian banks of deposit (deposit) transactions with natural and legal persons"). But the above rule applies only to deposits in national currency. Deposits in foreign currency, unless otherwise stipulated in the contract, the bank is obliged to charge interest on the Classifier of foreign currencies, approved by the Board of the National Bank of Ukraine of November 4, 1998 (as amended on October 2, 2002 378). In Part 2 of Art.

1061 Civil Code of Ukraine stated that the bank has the right to change the rate of interest paid on demand deposits, if otherwise agreed. Changing the amount of interest on demand deposit may be a way to increase or decrease in interest rates. Law establishes the procedure for the bank's actions in the case of reducing the size of percent. Thus, the institution must inform the depositor of the bank to reduce the amount of interest. And only one month after the notification to the account (deposit) may apply the new (reduced) rate of interest. Emanating from the provisions of Art. 1061 Civil Code of Ukraine, we should recognize that such information should be conveyed to the investor and such data, if available of litigation, the court must be provided.
