Özet:

Along with globalization and the development of technology, commercial activities that are increasing both domestically and with imports and exports have brought banks and the banking sector to an important point in terms of economy. Banks' financial performance researches are generally one of the most important issues in terms of both theory and practice. In the literature, it is seen that many multi-criteria decision making methods are used for financial performance measurements. In the study, it is aimed to measure the financial performances of 20 public, private or foreign capital banks operating in Turkey with BWM-based TOPSIS, PROMETHEE and COPRAS methods and to interpret the findings comparatively. In the study, banks are evaluated by determining 10 criteria under the CAMELS variables. At the same time, the results of the ranking of the banks obtained as a result of the study are compared with the Spearman rank correlation analysis. The study involves the years between 2009 and 2020. As a result of the study, it is concluded that public banks have higher performance and the findings of all three methods are similar in terms of methods, but the PROMETHEE method is more applicable in terms of ease of application and useful information it provides. It is thought that these results would contribute to the literature of multi-criteria decision making methods and the banking sector.
