This study aims to evaluate the performance of G20 economies. For this purpose, financial sector-based factors are taken into the consideration. Within this framework, 9 different indicators are identified. As a result of DEMATEL analysis, it is concluded that domestic credit provided by financial sector is the most important indicator whereas the indicator of automated teller machines has the weakest importance. In addition to this aspect, with the help of TOPSIS methodology, it is identified that Italy has the best performance while Argentina is on the last rank. While considering these aspects, it is recommended that G20 countries should focus on the significant criteria emphasized in the study in order to increase their performance.
