Four African cities—Casablanca, Johannesburg, Maurice, and Kigali—have taken different paths to establish themselves as financial hubs. While they have successfully attracted businesses and investors, their next challenge is more complex: transforming this appeal into deeper financial markets and the ability to effectively move capital. On Friday, October 2, the Casablanca Business Forum marked a shift in focus. The discussion is no longer just about attracting more investors to Africa but about building local institutions, markets, and tools that can effectively mobilize the savings already present on the continent. Casablanca has risen 11 positions in the Global Financial Centres Index 40, published on September 16, reaching the 38th global ranking. It is now the top African city in the ranking and the third in the Middle East-Africa region, behind Dubai and Abu Dhabi. The Casablanca Finance City (CFC) claims more than 300 member companies and around 9,400 employees, with its firms operating in 53 African countries. According to Lamia Merzouki, deputy general director of CFC, nearly 20 billion USD of projects in Africa are currently managed by teams based in Casablanca. Managing a project from Casablanca does not necessarily mean that the capital was raised there, that the fund is domiciled there, or that the transaction was executed there. The boundary between a business center and a financial center now lies in the ability to structure, intermediate, and reallocate capital. Africa has not produced a single model. Johannesburg remains the reference in terms of financial depth. South Africa has large pension funds, insurers, asset managers, and a developed capital market, fueled by significant domestic savings. Mauritius has built itself differently, specializing in fund domiciliation and administration, investment vehicles, and cross-border operations. The market does not present this specialization as a direct confrontation with other hubs. Sanjay Bhunjun, president of the Economic Development Board, described in an interview with Gulf Business in June the Mauritian republic as a "complementary partner" of major financial centers rather than their rival, especially for investors seeking exposure to Africa. Kigali, much more recent, is trying to build a specialization around asset management, fintech, and climate finance. Casablanca pursues a more hybrid strategy. CFC wants to host both financiers, multinationals, international law firms, and regional headquarters. "If I take Mauritius, it is a place that has positioned itself on specific niches, particularly investment funds and fund administration," explains Lamia Merzouki. And unlike the Dubai model, which concentrates in the same ecosystem banks, funds, hedge funds, insurers, family offices, wealth managers, markets, and legal infrastructure, Casablanca does not claim to be a copy of this model. CFC, on the contrary, wants to distinguish itself from a purely offshore or fiscal logic. "We do not want to attract only for the taxation," insists Lamia Merzouki, who says she prefers the installation of teams managing the African activities of international groups. This logic explains the emphasis placed by CFC on "people flow" and "capital flow": mobility of talents on one side, flexibility in the management of currencies on the other. The model has allowed Casablanca to gain visibility. The question is now whether it can also produce financial depth. The real gap is in depth. The figures show how the situations remain contrasted. In 2025, the capitalization of listed companies represented about 327% of the South African GDP, compared to 62.5% in Morocco. In the UEMOA, the total capitalization of the BRVM, combining stocks and bonds, represented about 18% of the regional GDP. The same gap appears in bank financing. Private sector credit was equivalent to nearly 78% of the Moroccan GDP and about 89% of the South African GDP, compared to levels often below 30% in several West African economies. Lionel Zinsou, former Beninese prime minister and co-founder of SouthBridge, draws a simple conclusion: "We must treat finance as an industry." In other words, the ability of an economy to finance its transformation depends less on the number of banks or funds it hosts than on the depth of its markets, its institutional investors, and its ability to transform savings into credit and equity. CFC acknowledges this boundary. "We do not do deal making. We are not a stock exchange," recalls Lamia Merzouki. Her role is to create the environment, attract the actors, and facilitate their operations; investment decisions remain those of the banks, funds, and investors present in the ecosystem. The capital exists, but remains difficult to deploy. This is probably the main African paradox. The continent has more than 2,100 billion USD of institutional assets managed by pension funds, insurers, and sovereign funds, according to the African Development Bank. Didier Acouetey, special advisor to the president of the AfDB on the new African financial architecture, estimates that the challenge is less about finding new resources than about better articulating those that already exist. Mobilizing only 20% to 30% of these capitals, by strengthening guarantee mechanisms, would be sufficient to create a powerful lever effect. However, the lock is not only regulatory or financial. The Organization for Economic Co-operation and Development (OECD) also notes an internal skills deficit: many African pension funds do not yet have the necessary teams to assess the risks of an infrastructure project or conduct due diligence on non-listed investments. Nigeria illustrates this limit. Its regulation allows certain pension portfolios to allocate up to 15% of their assets to private equity. However, alternative investments remain marginal in the portfolios. For African financial centers, the next battle could thus consist less in attracting more money from London, New York, or Dubai than in circulating more African savings between African markets, as emphasized by Alain Ebobissé, CEO of Africa50. CFC is working with the AfDB on financial integration and new instruments for mobilizing the private sector. It is also trying to build a specialization in sustainable finance, particularly around the carbon market, and aims for 500 member companies by 2030.
