None of the interested investors were "suitable" to buy the stake at this stage, the South African Reserve Bank (SARB) said in a statement.

The central bank took control of the lender in 2014 following a bad loans crisis and began the process to sell its stake in early 2020.

The timing of the IPO will depend on market conditions, the SARB said. A surge in market volatility in recent weeks due to the Russia-Ukraine crisis has forced several companies to delay their market debuts.

Other investors in ABHL include big South African lenders from FirstRand to Standard Bank and a government employee pension fund.
