“The stress in the MFI business was an MFI industry issue and looks like it is behind us. Other than MFI, the asset quality of the Bank has always been stable for over a decade through cycles and continues to be so with Gross NPA at 1.86% and Net NPA at 0.52% as of 30th September 2025. On cost of funds, we expect it to drop from here on. The bank is witnessing improving operating leverage. For instance, in FY25, total Business, i.e. loans and customer deposits, grew by 22.7% YoY, against increase in Opex of 16.5% YoY. Following on, in H1 FY26, total Business grew by 21.6% YoY, against Opex increase of 11.8% YoY. We hope to sustain this trend,” said V Vaidyanathan, MD and CEO of ISFC First Bank.
On Friday, the shares of IDFC First Bank closed flat at Rs 71.91 on the BSE.
