Since the financial reforms of 1991, the Indian banking system has undergone significant changes, positioning itself as a modern banking sector. This study focuses on examining the financial performance and profitability of both old and new private sector banks in India following the financial crisis. The research spans a 15-year period from 2000 to 2015, considering seven new private sector banks and twelve old private sector banks. The study aims to address the research gap by comparing the financial performance of old and new private banks, analyzing three major components, and investigating the impact of the financial crisis. The findings reveal differentiated impacts on bank profitability determinants, with the new private sector banks outperforming their older counterparts. This study underscores the importance of understanding the crisis's impact and fostering continuous improvement and adaptation within the Indian banking sector, particularly for the older private sector banks, to thrive in a dynamic and competitive environment.
