IDBI Bank Ltd. was incorporated in 1964 as a development financial institution and was converted into a full-service commercial bank in 2004-05. While IDBI became a public sector bank only in 2019 (through government acquisition), its conversion to a bank status occurred during 2004-05. The other options are private sector banks (ICICI, Yes Bank which was founded in 2004, and UTI Bank which later became Axis Bank).
