The Central Bank of Russia published its December 2025 monitoring results for maximum interest rates on Russian ruble household deposits at the 10 credit institutions attracting the largest volume of household deposits, reporting an average maximum rate of 15.63% for the first 10 days of December. The average maximum rate is calculated as the arithmetic mean of each bank’s maximum publicly available deposit rate, excluding offers limited to special client categories or purposes, products with compound interest, rates conditional on meeting requirements (such as card turnover or minimum balances), combined deposit products with additional conditions (including investment or insurance-linked requirements), and deposits with stepped rates across sub-periods. For reference, the Bank of Russia reported average maximum rates by maturity of 15.02% (up to 90 days), 15.24% (91–180 days), 14.47% (181 days to one year), and 12.42% (over one year).
