HDFC Bank has appointed former finance secretary Rajiv Kumar as the part-time Chairman for three years, according to an exchange filing on Monday. The appointment comes after Atanu Chakraborty, the former part-time chairman quit citing practices that he said were not aligned with his personal values and ethics. In his resignation letter he clarified that his decision was based on matters of principle and that there were "no other material reasons" behind his exit, causing a stir in the banking world. Keki Mistry has been serving as the part-time chairman of HDFC Bank in the interim, after being appointed post Chakraborty's abrupt exit in March 2026.
