The suspension, with immediate effect, comes a day after the South African Reserve Bank announced a 17 billion rand rescue plan for the unsecured lender widely known as ABIL.
The central bank put ABIL, which has been hammered by waves of bad debts, under curatorship, or outside supervision, as part of the rescue plan.

The central bank will pay seven billion rand for ABIL's “bad loan” book, while a consortium of commercial banks including Standard Bank have agreed to underwrite a 10 billion rand capital raising.
“The board of the company considers that the suspension is in the public interest,” ABIL said in a statement, adding that it would also apply to have trade of its securities suspended on exchanges outside of South Africa.
ABIL shares are also traded in the United States and Germany and it has debt denominated in US dollars and Swiss francs.
