Banks boost the economy's growth. But, banks have major issues with overdue, unpaid loans called Non-Performing Assets (NPAs). Many reports show NPAs are rising rapidly, showing the problem's seriousness. Researchers study NPAs, looking at their status, causes, impacts, and effects. On a large scale, the rising bad debts hinder economic growth and affect diverse people, businesses, and banks. This article gives a brief summary of banking, explains bad debts, and looks at possible reasons for their increase. Our main goal is to clarify the major impacts of many bad debts on banks. We carefully study each potential effect using existing research. Studies show NPAs hurt banks. Our research uses data already collected to understand NPA problems in India. We carefully examined papers and statistics. NPAs cause major issues for banks. Profits go down. Credit ratings worsen. Banks cannot lend as much. Funding becomes more costly. We cite research to explain each effect. This gives a full picture of how NPAs impact banks. To conclude, this paper combines the effects of bad loans and suggests ways banks might take to fix this problem. It stresses how crucial immediate actions and smart plans are to get through this tough situation and protect the banking industry's stability and strength.
