Michiel Le Roux

Who Michiel Le Roux is

Michiel Le Roux is a founder of Capitec, the bank that took South African retail banking apart by charging people less. His fortune is the most straightforward on this index to understand and among the easiest to verify: one stake, one listed company, one idea executed for twenty-five years.

As of mid-2026, Capitec had the largest market capitalisation of any South African commercial bank, at R566 billion — larger than institutions that were a century old when it opened.

Where Capitec came from

Capitec was formed in 1997, through the acquisition of micro-lending businesses including Smartfin and Finaid by the founding entity, PSG. Its founders are Jannie Mouton, Michiel Le Roux and Riaan Stassen. It registered as a bank in 2001 and trades on the JSE under CPI.

The lineage matters. Capitec did not begin as a bank with a plan to serve poor customers; it began as a collection of micro-lenders — the businesses that made small, short, expensive loans to people the big four would not touch. What the founders did was take that customer base and give it a bank.

Several other people on this index come out of the same PSG stable: Chris Otto, a PSG co-founder, was a founding director of Capitec, and Piet Mouton later ran PSG. The Mouton network is one of the two or three most productive wealth-creating clusters in modern South African business, and Capitec is its best single outcome.

The idea

South African retail banking before Capitec ran on a particular arrangement. Fee structures were complicated enough that few customers could predict what a month would cost them. Charges were levied per transaction, per enquiry, per withdrawal, per statement. Branch hours suited the bank. A customer with a low balance was, in the language of the industry, unprofitable, and was priced accordingly.

Capitec's proposition was almost aggressively simple: one account, a single transparent fee structure, branches open when working people are not at work, and an assumption that a customer earning a modest wage is worth having rather than worth deterring.

None of this was technically difficult. That is the striking part. The incumbents had better balance sheets, better funding, more branches and more data. What they did not have was a willingness to compete for a customer they had already written off — and by the time they took the threat seriously, Capitec had a decade's head start and a cost base built for the job.

The scale it reached

As of September 2025, Capitec served 24.1 million individuals — 38 per cent of the South African population. It has the country's largest branch network at 880 branches and the largest ATM network at almost 9,000.

Thirty-eight per cent of a country is not a market share; it is closer to infrastructure. For a very large number of South Africans, Capitec is not their preferred bank but the first formal financial institution their household has ever dealt with. That has consequences beyond the share price: an enormous share of the country's payment behaviour, credit records and savings now runs through a single institution that did not have a banking licence in 2000.

What it did to everyone else

The clearest evidence that the idea worked is not Capitec's numbers but its competitors'.

Every one of the big four now sells a low-cost, flat-fee bundled account aimed at exactly the customer the industry had previously priced away. Branch hours moved. Fee disclosure got simpler, because a customer who can price one account against another will. None of that was the product of a regulator forcing it; it was a competitive response to losing millions of customers to a bank from Stellenbosch.

That is the part worth holding onto for anyone reading this site for their own sake rather than out of curiosity about rich people. The reason South African banking costs less to use than it did twenty years ago is that one competitor decided a low-income customer was worth having. Fortunes built by lowering a price tend to be better for the country than fortunes built by controlling one, and this index contains examples of both.

The part that is not a fairy tale

An honest profile has to note where the model carries risk, because it is the same risk that made it possible.

Capitec grew out of micro-lending, and unsecured lending to lower-income borrowers is the most cyclically dangerous business in retail banking. It performs well while employment holds and badly when it does not, and the losses arrive quickly because the loans are short. South Africa's unsecured lending market has had at least one serious reckoning in living memory, when an over-extended sector met a slowing economy and a major lender did not survive it.

A bank serving 38 per cent of the population also carries a concentration that is not really its own to manage: its credit book is a fairly direct read on South African household income. Whatever happens to employment happens to this share price, and therefore to this entry on the index, with very little that management can do about it.

Stating that is not a prediction. It is the context a reader needs to understand why a figure built on a single bank holding can move sharply without anyone having done anything wrong.

How Rateweb values him

This index records Le Roux's Capitec holding as a disclosed stake, converted into a fixed number of shares and revalued at the current JSE price — the same treatment the methodology describes for every listed holding. Capitec is one of the twelve companies for which we carry a market capitalisation, so this entry actually moves when the market does, rather than sitting as a frozen constant.

This entry was corrected in September 2026, and the correction was large. The index previously carried a 9.8 per cent stake with no recorded provenance, valued against a Capitec market capitalisation of R326 billion. Both figures were stale, and both were stale in the same direction.

Reporting dated 8 July 2026 records that Le Roux holds more than 10 per cent of Capitec, across two vehicles named Kalander Sekuriteit and Limietberg Sekuriteit, and that Capitec is now worth about R566 billion. The same report notes he pledged 1,374,356 Capitec shares through Kalander to secure a loan of roughly R6.56 billion, and that Forbes puts his total fortune at about R62 billion.

We now carry the stake at 10 per cent — a floor, taken under the lowest-sourced-figure rule in our methodology, because “more than 10 per cent” is what the source actually says. Secondary reporting puts it nearer 11.3 per cent, but we have not read that in a document we can cite, so we do not use it. The effect of the correction is to roughly double this entry.

One honest wrinkle remains. A pledged share is still beneficially owned and is correctly counted here — but a stake encumbered against a loan is not a freely disposable one. This index does not distinguish the two anywhere, for anybody, and that is a general limitation rather than something specific to him.

The remaining verification is bounded: Capitec's annual report tabulates shareholders above the disclosure threshold, and it will give an exact percentage rather than a floor.

What a founder's stake does over twenty-five years

Capitec is the clearest illustration on this index of why founding stakes produce fortunes that salaries never can.

A founder who keeps a single-digit percentage of a company that grows from a micro-lender into the most valuable bank in the country does not need to do anything else, ever. No further capital, no new ventures, no trading. The position compounds because the underlying business compounds, and the only decision that mattered was not selling.

It is also why this index treats disclosed listed stakes as the gold standard of evidence. Le Roux's wealth is not a matter of opinion about private assets. It is a share count multiplied by a price that anyone can look up, and the arithmetic is the same whoever does it.

The contrast with Natie Kirsh a few places above him is instructive. Both men built something large and kept it. One did it inside a listed company, so his figure can be checked by a stranger with an internet connection; the other did it inside a private one, so the published estimates of his wealth vary by more than ten billion dollars. Nothing about the quality of the two businesses explains that gap. Disclosure does.

What we do not know

What he has sold. Founders diversify, and a stake disclosed at one date is not a stake held forever; our figure depends on a percentage that needs checking against the current annual report. We also do not know what sits outside Capitec — private investments, property, philanthropy and family structures are not disclosed, and Le Roux keeps a notably low public profile for someone who built an institution this size.

We also do not attempt to separate what is held personally from what sits in family trusts or investment vehicles. A disclosed major-shareholder line in an annual report names the registered holder, which is not always the same thing as the beneficial owner, and reading a person's wealth straight off it can overstate or understate depending on which way the structure runs. Where the document does not distinguish, neither do we.

If you can point us at the current shareholder disclosure, tell us — that single document would move this entry from pending to verified.
