The paper considers the peculiarities of Ukraine’s deposit market functioning in 2020–2023 under the influence of force majeure factors. The current state of the respective market was analysed in terms of types of deposits by duration, namely fixed and demand, by types of currencies in which funds are placed on deposits, by ranges of the size of the deposits themselves, etc. Approaches to the interpretation of the “deposit operation” concept were systematized. Having analysed the definitions it is possible to define a “deposit operation” as an operation involving the deposit institution’s attraction of funds (in national or foreign currency, in cash or non-cash form) or bank metals of depositors to deposit bank accounts under the terms of the concluded agreement and following the current legislation of Ukraine. A comprehensive analysis of the dynamics of the deposit portfolio of the banking system was carried out. The dynamics of deposits of individuals in the banking system of Ukraine were analysed. The dynamics of interest rates on deposit deposits in terms of subjects, currencies and duration are highlighted. The increase in deposit rates contributed to the recovery of the growth of fixed deposits of individuals which volume increased for the first time since the beginning of the war. The permission of the National Bank to buy foreign currency to open fixed currency deposits contributed to their growth in dollar equivalent. The peculiarities of the activity of the Deposit Guarantee Fund in Ukraine during the period of martial law were identified, and the impact on the level of public trust in banks was investigated. The obtained results of the conducted research made it possible to determine the main trends in the development of the deposit market of Ukraine and to outline proposals for improving the deposit policy of Ukrainian banks.
