Abstract
The sustainability of the banking industry increasingly depends on the effective integration of traditional financial soundness indicators with environmental, social, and governance (ESG) risk considerations. In this research, a novel grey-based group decision-making framework is developed to assess the multidimensional CAMELS–ESG risk performance of banks operating in Turkey under conditions of uncertainty and incomplete information. The suggested methodology integrates the grey extensions of the Grey Symmetry Point of Criterion (G-SPC) and Grey Preference Selection Index (G-PSI) methods to objectively determine criterion importance weights, which are subsequently aggregated through a newly developed linear weight integration operator. The ranking of bank alternatives is then derived using the Grey Ranking of Alternatives by Criterion Weights (G-RAWEC) approach. The empirical analysis is conducted on eight deposit banks using six CAMELS-based financial indicators and one ESG risk criterion. The results reveal that ESG risk, impaired loans to gross loans, and liquid assets to deposits constitute the most influential factors in shaping banks’ overall multidimensional performance. The ranking outcomes indicate that Akbank achieves the highest performance, followed by Yapı Kredi Bank and Garanti BBVA, whereas Şekerbank, QNB Finansbank, and Vakıfbank exhibit relatively lower performance levels. Extensive robustness and sensitivity analyses-including parameter variation, comparison with alternative grey-based MCDM methods, rank reversal testing, and criterion elimination scenarios-confirm the stability, reliability, and internal consistency of the proposed framework. This study contributes to both the banking performance and MCDM literature. The proposed framework offers a transparent and practically applicable decision-support tool for regulators, bank managers, and investors seeking to assess banking performance in uncertain and complex decision environments.
