South African billionaire Michiel Le Roux gained 1.1 billion from his Capitec Bank stake in 2025 as shares of the leading retail bank climbed sharply on the Johannesburg Stock Exchange, lifting his long-held stake in Africas largest retail lender. The gains came during a year when investors returned to South African banking stocks, thanks to steady earnings and a firmer rand.
Le Roux, who co-founded Capitec more than two decades ago, owns an 11.36 percent stake in the bank, equal to about 13.19 million shares. Since the start of the year, the value of that holding has risen by roughly R13.89 billion, or 1.11 billion. The increase reflects a strong run in Capitecs share price as well as the appreciation of the rand against the U.S. dollar, which boosted returns for investors measuring their gains in dollar terms.
