In this study, the financial performance of public and private deposit banks, which are members of the Turkish Bank Association (TBB) and subject to the BIST Banking Index, were analysed comparatively. In analysing the financial ratios of 9 deposits between 2019 and 2021, a hybrid model was used in the ENTROPY-based MULTIMOOSRAL method. As a result of the study, it has been determined that the most important financial ratios are profitability ratios; the best performance in 2019 is that public deposit banks and private deposit banks are at the top. However, it was determined that public banks could not perform successfully until 2021. Contrary to the performance of public banks, it was determined that private deposit banks maintained stability, and some of the private deposit banks, which were initially in the lower ranks, followed a performance of 4 to 5 ranks higher.
