ECL is a forward-looking accounting standard that requires banks to make provisions on expected losses based on past asset quality, instead of incurred loss-based provisioning. The already created buffer would come into play from the first quarter of FY28. "Banks with higher floating and contingent provisions would be less impacted by the ECL provisioning norm. Typically, a few large private banks have built material floating provisions as compared to their public sector peers," Icra senior vice president and co-group head Anil Gupta told ET.
