Abil collecting $230m of debt a month
African Bank, known as Abil, was rescued by the central bank in August after it was hit by a flood of bad debts as its core market of low-income borrowers failed to repay loans.
"The collections are at least as good as we expected, and have even been slightly above," he said.
The central bank initially said it would buy 17 billion rand of bad loans for 7 billion rand. However, Winterboer said he now he believes those loans were collectible and Abil would instead take a 7 billion rand facility from the central bank and keep the bad debt book itself.
"We've actually submitted a new banking application for a new licence, for the good bank. That went in yesterday."
The bank's loan volume for October is likely to be as much as 680 million rand, Winterboer said.
The central bank has also launched an investigation into Abil and its former management to determine if the bank engaged in reckless conduct or questionable practices.
