South Africa’s $30 billion succession: what the Rupert, Oppenheimer and le Roux heirs inherit

The three men behind South Africa’s largest private fortunes are 76, 77 and 81. Their sons stand to inherit very different things, and only one of them is being groomed in public.

South Africa’s three largest fortunes belong to men born before 1951. Johann Rupert, chairman of Swiss luxury group Richemont, is 76 and worth roughly $15 billion on recent market estimates. Nicky Oppenheimer, 81, whose family controlled De Beers for more than 80 years, holds about $10.8 billion. Michiel le Roux, 77, co-founder of Capitec, has about $3.8 billion. Together they account for close to $30 billion, a sum that moves with the share prices of a Geneva-based luxury group and a Stellenbosch bank.

Each man has a son in line. The resemblance ends there. Anton Rupert, 39, is being placed inside the governance of a listed company his family controls with a minority of its equity. Jonathan Oppenheimer, 56, already runs a family office whose wealth was converted to cash 14 years ago. The younger Michiel le Roux built his own lender elsewhere in Africa and has no role at Capitec. For investors in Richemont, Remgro and Capitec, those differences decide how much a change of generation will be felt in the boardroom and on the share register.

Richemont puts its succession plan on the record

On September 9, Richemont named Anton Rupert non-executive co-deputy chairman, with immediate effect. He shares the title with Bram Schot, 65, the former Audi chief executive who joined the board in 2023 and became deputy chairman in 2024. The board split the job. Schot handles governance and the coordination of board committees; Rupert oversees the Strategic Product and Communications Committee, which sets product and messaging priorities across Cartier, Van Cleef & Arpels and the group’s other maisons. Johann Rupert called the appointment “an important step in the Board’s long-term succession planning.”

The younger Rupert has sat on Richemont’s board since 2017 and has also served as a director of Remgro. He keeps a low public profile. His best-known roles have been at family concerns such as L’Ormarins, the Rupert wine estate in Franschhoek, and the Franschhoek Motor Museum.

Outside shareholders should care because of the share structure. The Rupert family owns roughly a tenth of Richemont’s equity but controls just over half of its votes through unlisted B shares held by Compagnie Financière Rupert. At Remgro, the Stellenbosch investment group whose holdings include Mediclinic, OUTsurance and FirstRand, unlisted B shares give the family about 43% of the votes. Reinet, the Luxembourg investment company, is controlled through management shares. Whoever inherits those instruments inherits control of all three companies, however few ordinary shares change hands.

The division of labor says something about intent. Giving the heir the product brief keeps the family’s hand on the creative side of the business, and jewelry was what carried Richemont’s 11% constant-currency sales growth in the year to March 2026. Handing governance to an independent former car executive places an outsider in charge of the area where minority shareholders are most sensitive. It is a sensible arrangement. It also leaves the central question unanswered: whether Anton Rupert will one day chair the group, and when. The board has not said.

The Oppenheimers made their big decision in 2012

The Oppenheimer succession has largely happened already. Jonathan Oppenheimer is executive chairman of Oppenheimer Generations, the Johannesburg firm that runs the family’s investments and its philanthropy; his father is its chairman. He began his career at NM Rothschild & Sons in London and spent about two decades in senior roles at Anglo American and De Beers.

The decisive move came in 2012, when the family sold its 40% stake in De Beers to Anglo American for $5.1 billion in cash. That ended a connection that began when Ernest Oppenheimer, who founded Anglo American in 1917, took control of De Beers in 1929. In hindsight the timing was good. Laboratory-grown stones have since pushed down prices for natural diamonds, and in 2024 Anglo American put De Beers up for sale.

What Jonathan Oppenheimer inherits, then, is a portfolio. The industrial franchise went in 2012. Oppenheimer Generations set up Tana Africa Capital with Singapore’s Temasek to invest in African consumer businesses, and it runs the Brenthurst Foundation and the Tswalu Kalahari Reserve in the Northern Cape. A family office carries its own kind of succession risk: returns thin out as capital is divided among a growing number of descendants, and nobody outside the family can see it happening.

Capitec’s founder keeps his stake and his son keeps his distance

Le Roux co-founded Capitec in 2001 with the backing of Jannie Mouton’s PSG and chaired it from 2007 to 2016. The bank grew by offering low fees and simple accounts to customers the established banks served poorly, and in July it was valued at about R556 billion on the Johannesburg Stock Exchange. Le Roux remains its largest individual shareholder, with more than 10% held through his investment company, Kalander Sekuriteit.

He also borrows against that holding. In July, Kalander refinanced a hedging arrangement over 1,374,356 Capitec shares, then worth about R6.56 billion, using the stock as collateral for a loan. Founders often use such structures to raise cash without selling. They also leave a large block of stock subject to a counterparty’s terms, and Capitec’s shares fell on the day the transaction was disclosed.

His son, also named Michiel, has gone his own way. A Rhodes Scholar educated at Stellenbosch, Melbourne and Oxford, he worked in investment banking at Absa Capital and Barclays Capital and then in private equity at Barak Fund Management. In 2015 his group acquired a Zambian microlender with roots going back to 2007, which he has since built into Unifi, a lender operating in Zambia, Uganda, Kenya, Tanzania and South Africa. He is its chief executive. During the 2009 election he volunteered for the Congress of the People, a breakaway from the ANC, and published a book about the experience the following year.

From outside, the le Roux succession is the hardest to read. A founder’s stake of this size, with no heir on the board, will eventually pass through an estate, a trust or a sale, and each route has different consequences for Capitec’s shareholder base. The father’s other commitments add a public dimension. He has been the largest reported individual donor to the Democratic Alliance, and he founded and chairs the Millennium Trust, which funds investigative journalism and civil society groups. Whether either commitment outlasts him depends on decisions nobody has announced.

What each heir actually receives

Side by side, the three families show the main options open to founders. The Ruperts are passing on control: a voting structure that lets a family with modest equity direct a global luxury group and two investment companies. The Oppenheimers are passing on capital, spread across many holdings since 2012. The le Roux family is passing on a stake, a large holding, part of it pledged against loans, in a business the heir does not run.

Each model gives boards and investors something specific to watch. Dual-class control concentrates succession risk in one person’s readiness, and Richemont has been unusually open in staging that transition early. A family office carries less market risk and more governance risk within the family. A founder stake without an operating heir is the most likely of the three to change hands, which at some point means either block sales on the market or a new strategic holder.

“Succession in family-controlled companies is decided long before the founder steps back. At Richemont, the real inheritance is a share class, and investors should judge the heir by how that voting power is used, not by the family name,” said Prof. Dr. Amarendra Bhushan Dhiraj, CEO and Editor-in-Chief of CEOWORLD Magazine, Managing Director of CEO ATELIER, a global economic strategist, and the bestselling author of Between Olympus and the Ganges: How Greece and India Shaped the Modern Mind.

“In luxury, continuity of taste carries real commercial value. Placing the next generation in charge of product and communications keeps a house’s creative identity in steady hands, provided that judgment is tested openly before the chairmanship ever changes.”

Executive takeaways

What changed is that Richemont has formally placed the next Rupert in its leadership line, the clearest succession signal yet from any of South Africa’s three largest fortunes.

It matters because family control of Richemont, Remgro and Reinet rests on special share classes, so governance at all three depends on how and when those instruments pass to Anton Rupert.

Leaders and investors should watch three things: Richemont board statements on the chairmanship, any change in the Rupert family’s B-share vehicles, and Capitec filings on le Roux’s hedging and financing arrangements, which are the earliest public evidence of how the largest founder stake in South African banking will eventually move.

Johann Rupert has chaired Richemont since 2002 and has given no date for stepping back. Of the three heirs, his son has the most to inherit and the thinnest public record by which investors can judge him. The co-deputy chairmanship is the first role in which his decisions will be visible, and the next two years of product and brand choices at Cartier and its sister houses will be the closest thing shareholders get to an audition.
