Built for Itself.
Mauritius is Africa’s foremost international financial centre, built to route private capital into the continent. South Africa is not a competitor to Mauritius in the way that Kigali or Casablanca are. It never was. The two were built for different jobs, and the difference between them is the difference between routing capital and retaining it.
Mauritius is a small Indian Ocean island that became the leading international financial centre (IFC) through which a large share of the world’s private and institutional capital is routed into Africa: the structuring layer for private equity, venture capital and development finance, built on global business company (GBC) fund structures, double taxation agreements (DTAs), and common-law courts. The Capital Codex concerns this private-capital routing layer, not domestic or retail banking. This excerpt looks at the neighbour usually mistaken for a rival: South Africa, whose financial system, banking included, was built to serve its own economy rather than to route external capital, which is why a routing hub and a retaining economy were never in the same race.
South Africa’s financial system was built for South Africa, to serve a domestic economy, a domestic capital market, and domestic institutional investors. The JSE, the GEPF, the domestic banking system: these were not designed to attract or route foreign capital flows. They were designed to intermediate within.
The proof is in the structure. The GEPF operates under the Government Employees Pension Law, not Regulation 28, with a specific offshore investment ceiling, raised from 10% to 15% in 2021 following negotiations with the Finance Minister. Even at 15%, the GEPF held only 13.7% offshore as of March 2024 (R319 billion of R2.38 trillion). The GEPF’s R2.38 trillion is built to stay largely in South Africa. It is not a pool that Mauritius routes. It is a pool that South Africa keeps.1
The relationship between Mauritius and South Africa is therefore not competitive; it is structural. Mauritius routes capital from European DFIs, global LPs, and non-South African investors into African markets. South Africa generates and retains its own capital. The two systems operate on parallel tracks that rarely intersect.
What South Africa does represent, and this is the more subtle pressure, is a gravitational centre that makes the Mauritius routing argument harder to sustain for pan-African deals. When South African capital is being deployed into East Africa, or when South African GPs structure regional funds, the question naturally arises: why route through Port Louis rather than Johannesburg, which has deeper capital markets, stronger institutional infrastructure, and no offshore premium to justify? South Africa does not displace Mauritius. But its scale and sophistication raise the comparison. And in an era when every layer must justify itself, being compared unfavourably to Johannesburg is a form of competitive pressure, even if the two systems were never in the same race.
South Africa was built for South Africa. But the size of what it built now creates a shadow over every smaller system in its region.
Delaware showed a rival that was never on the same track. South Africa shows something quieter: a neighbour so large that its mere existence reframes the question. The pressure on an intermediary is not always a competitor reaching for its position. Sometimes it is a giant next door who was only ever building for itself.
- The GEPF is established under the Government Employees Pension Law (Proclamation 21 of 1996) and sits outside the Pension Funds Act’s Regulation 28; its offshore ceiling is set by negotiation with the Minister of Finance, raised from 10% to 15% (concluded 2020, reported 2021). Foreign holdings were R319 billion, or 13.7% of assets, against a total portfolio of R2.38 trillion as at 31 March 2024. Sources: GEPF Annual Report 2023/24; GEPF actuarial report; National Treasury. The fund has since grown to R2.69 trillion (31 March 2025).
