Abstract: Performance evaluation in the banking sector is a critical framework for assessing a bank's effectiveness in achieving stability, profitability, and regulatory compliance. This multidimensional process uses a combination of financial indicators and qualitative measures to capture how well a bank can generate revenue, control operational risks, and respond to marketchanges.This paper presents an in-depth evaluation of IDBI Bank Ltd.'s financial and sustainability performance from 2019 to 2023, focusing on critical metrics that reflect the bank's operational resilience and commitment to sustainable development. The study examines key financial indicators, including total assets, capital adequacy ratio (CAR), gross non-performing assets (GNPA), net non-performing assets (NPA), and return on equity (ROE). Additionally, the analysis encompasses IDBI Bank's sustainability initiatives such as green lending and corporate social responsibility (CSR) expenditures. Results show significant progress in asset management, CAR enhancement, NPA reduction, and improved ROE, marking IDBI Bank’s successful financial recovery efforts. Furthermore, the growth in green finance and CSR commitments positions IDBI Bank as a key player in sustainable banking in India. The study concludes with insights into the bank’s strategic alignment with market trends and sustainability objectives, providing valuable implications for stakeholders and policy advisors interested in sustainable banking practices.
