This paper presents the current number, size and position of depository institutions in the financial system of the Republic of Croatia. For this purpose, available literature and recent data are used, paying attention to be harmonized in time. The analysis and descriptive analysis of all components of the financial system, and in particular of depository institutions, is conducted. Using tabular and graphical representations, the data relating to depository institutions and financial intermediaries are analyzed. The synthesis of the obtained results of the analyzes led to the conclusions and the final results of this paper. Among other, the paper finds that depository institutions have a dominant role in the financial system of the Republic of Croatia. Also, the paper came to the conclusion that depository institutions have a positive impact on the economy of the Republic of Croatia, because they direct citizens’ savings for establishment and functioning of companies. The financial system of the Republic of Croatia is traditional because banks (and thus depository institutions) are the most important financial intermediaries and they are the basis of the financial system. Nevertheless, based on the analysis of movement size of financial assets in the period 2014 – 2018, the paper finds that depository institutions have a slight decline in the importance in the financial system of the Republic of Croatia. However, considering that depository institutions (especially banks) in the Republic of Croatia continue to have a dominant position, it can be said that the financial system of the Republic of Croatia is still considered traditional.
