RBI introduced stricter NPA classification rules effective April 1, 2027, aligning India's banking system with global standards. Key changes include cross-default provisions where all loans of a borrower become NPAs if one defaults, Expected Credit Loss (ECL) methodology replacing Incurred Loss approach, and Effective Interest Rate (EIR) for loss estimation. Banks must use automated NPA identification systems. New loans follow EIR from April 2027; existing loans convert by March 2030. ECL operates in three stages based on credit risk levels.

These reforms represent RBI's most significant credit risk management overhaul in decades, designed to enhance early detection of stressed assets and improve provisioning adequacy. The cross-default mechanism prevents borrowers from gaming the system by maintaining payments on some loans while defaulting on others. ECL methodology is forward-looking, requiring banks to provision based on expected losses rather than waiting for actual defaults, similar to IFRS 9 standards adopted globally. This increases provisioning requirements initially but creates more resilient balance sheets. EIR provides a more accurate reflection of loan economics by considering all cash flows and fees, not just nominal rates. The three-stage ECL framework allows proportionate provisioning - Stage 1 for performing loans (12-month expected losses), Stage 2 for underperforming but not defaulted loans (lifetime expected losses), and Stage 3 for defaulted loans (lifetime losses with individual assessment). Implementation timeline provides banks sufficient preparation time while ensuring systematic adoption. These changes will likely increase provisioning costs short-term but strengthen long-term stability and international comparability of Indian banking metrics.
