This study examines the mergers and acquisitions (M&A) that have taken place in the Indian financial sector in order to understand the long-term effects of the merger as well as the cooperative synergies that followed. The study delves deeper into the observed patterns in the Indian financial system following mergers and acquisitions, and as a result, makes recommendations for future actions that institutions have to take into account. The research examines the effects of mergers and acquisitions by examining the trends and movements within the Indian banking sector. In order to analyse and assess the performance of M&As in the Indian financial sector, the article attempted to locate earlier research. The findings showed that although M&A in the Indian financial sector has been skillfully carved out, the economy has only reaped relatively small gains thus far. When merging strong banks with weaker banks, the government and policymakers should exercise caution because doing so could have a detrimental effect on the assets of the stronger banks rather than only serving to safeguard the interests of the troubled banks. The article also focuses on newly formed organisations and recently combined institutions. The report makes some recommendations based on accessible secondary evidence.
