Africa’s securities exchanges have raised well over $240 billion in debt and $87 billion in equity. Individual markets have posted index growth that would be remarkable anywhere.
Yet capital rarely moves between them. An investor in one African market is often more likely to hold US equities than securities from a neighbouring exchange. That is not a preference; it is a consequence of how the markets are built.
Fragmentation is structural, not cultural
The usual explanations — unfamiliarity, risk appetite, information gaps — describe symptoms rather than causes. Institutional investors are perfectly capable of researching a market they can actually reach.
The binding constraints are practical. Market participation is licensed per jurisdiction. Custody is per market. Currency conversion and repatriation are governed separately in each. Regulatory requirements differ and change.
The effect is that an investment firm’s opportunity set is bounded less by judgement than by where it already holds infrastructure.
The cost is borne twice
Investors hold more concentrated portfolios than they would choose. Diversification across African markets is available in theory and expensive in practice, so capital concentrates domestically and returns correlate with a single economy.
Issuers face shallower demand. A company listing in Accra is priced by the capital that can reach Accra, not by everyone who might want to own it. Thinner books, wider spreads, higher cost of capital — and, over time, fewer companies choosing to list at all.
Both effects reinforce each other. Thin markets deter investors; absent investors keep markets thin.
What has changed
Three things, over roughly the last five years.
The exchanges themselves have moved. Regional integration is no longer a conference topic. Exchange linkage initiatives are operating, and the African Securities Exchanges Association has been explicit that fragmentation is a structural constraint rather than an inconvenience.
Regulators are cooperating more and tolerating less. The perimeter is being enforced with unusual energy — Ghana’s SEC set an August 2026 licensing deadline and named platforms operating outside it; other markets have moved similarly. For legitimate participants this is welcome: a market where licensing is enforced is one where being licensed means something.
Infrastructure has become viable. What was previously bespoke — separate relationships, custody and currency arrangements per market — can now be provided as shared infrastructure by parties licensed in multiple jurisdictions. The fixed cost that made multi-market access uneconomic for mid-sized firms is being absorbed.
What integration actually requires
Not a single pan-African exchange. That has been proposed periodically for decades and remains politically implausible.
What it requires is more modest and more achievable: that an investment firm in one market can reach another without rebuilding its operational stack. Licensed access, custody that reconciles, currency that converts and repatriates, and regulatory standing in each jurisdiction — provided as infrastructure rather than assembled per firm.
That is the direction the exchanges, the regulators and the market are all now moving in. The remaining question is how quickly.
