Daniel Mminele, a former deputy governor of the South African central bank, is poised to be the new CEO of Absa Group Ltd., sources told CNBC Africa.

Absa had said Aug. 12 that it had completed the search for a new CEO. The source told CNBC that Mminele will succeed Maria Ramos at the helm of the group and unit Absa Bank Ltd. on Jan. 15, 2020. René van Wyk has been interim CEO since March following Ramos' retirement.

Mminele retired from the South African reserve bank at June-end.

However, Viv Govender, a senior analyst at Rand Swiss, told CNBC that appointing Mminele would not be a good fit for the bank in the context of the banking sector's shift online.

"You [want] somebody from the IT field, from the technology field … to run these banks going forward," Govender said in an interview.
