Stressed assets, which include NPAs, restructured loans, and written off assets, are a major economic risk for India's banking sector as stressed assets levels have increased. Stressed assets provide an important indicator of a bank's financial health. NPAs refer to loans where interest or principal has remained unpaid for 90 days or more. Restructured loans are problematic assets that have been modified through measures like extended repayment periods to avoid being classified as NPAs. Written off assets are loans that banks have removed from their financial statements through compensation. The high level of stressed assets, currently at 11.5% of total loans, poses a significant problem particularly for India's public sector banks.
