Abstract :This study aims to develop a comprehensive and multidimensional framework to assess sustainability performance in the banking sector. We propose the Banking Sector Sustainability Model (BSSM), which integrates six dimensions: social, innovation, governance, environmental, economic, and financial criteria. To determine the relative importance of these dimensions, the study employs the Interval-Valued Intuitionistic Fuzzy Best-Worst Method (IVIF-BWM). Then, banks are ranked using the Intuitionistic Fuzzy Weighted Correlation Coefficient (IF-WCC) method, allowing for comparison based on diverse and heterogeneous data. The results reveal that expert groups have different priorities, with some highlighting environmental concerns and others prioritizing economic factors, indicating the framework\\\'s potential to capture diverse stakeholder perspectives. Sensitivity analyses confirm the stability and reliability of the proposed approach. Overall, the study proposes novel and practical tool for evaluating sustainability in the banking sector. The framework can support decision-makers, financial institutions, and researchers in promoting sustainable banking and enhancing transparency and accountability in the sector.
