The Central Bank of Russia released its December 2025 monitoring results on the average maximum interest rates on Russian-ruble deposits offered by the top 10 credit institutions attracting the largest volume of household deposits. The reported average maximum rate was 15.63% for the first 10 days of December and 15.38% for the second 10 days. The calculation reflects the arithmetic mean of each bank’s maximum publicly available deposit rate without limitations or preliminary conditions, and excludes products for special client categories, compound interest deposits, deposits conditional on meeting requirements (such as card turnover or minimum balances), combined products linked to investment or insurance features, and deposits with step-up or varying rates across sub-periods. For reference, the average maximum rates by maturity were 14.82% (up to 90 days), 15.02% (91–180 days), 14.40% (181 days to one year), and 12.37% (over one year), based on information from the banks’ websites.
