Every month, a nurse in Manchester wires her sister’s school fees to Harare. A driver in Houston sends rent money to his mother in Lagos. A teacher in Johannesburg pays a cousin’s hospital bill in Bulawayo. None of them call this development finance. They call it family.

But add up those wires and you get one of the largest capital flows on the continent. Remittances to Africa were estimated at somewhere between US$95 billion and US$100 billion in 2024, depending on the source, and the World Bank says they reached a fresh high in 2025. That is more than the continent received in foreign direct investment. It is more than official development assistance. Strip out one-off mega-deals, like the single urban development project that accounted for more than a third of Egypt’s 2024 FDI figure, and remittances stand alone as Africa’s steadiest external financing line.

Zimbabwe is a clean example. Diaspora remittances hit US$2.45 billion in 2025, up 14% on the year before, and now account for roughly 15 to 17% of the country’s foreign currency earnings. That places remittances alongside mining and exports as one of the few dependable sources of hard currency in the economy. Nigeria, Egypt, and Morocco anchor the continental totals. Kenya and Ghana follow close behind. This is structural money, woven into national accounts and household survival alike.

Giving that built things

Diaspora giving in Africa has never been only about wiring cash for consumption. It has a long organising tradition behind it.

Hometown associations in Ghana have funded classrooms, libraries, and bridges for decades. Members scattered across the UK, the US, and the Gulf pool their contributions and send them home together. Kenyan diaspora groups from counties such as Kiambu and Kakamega have financed schools and scholarships the same way. Giving circles work on the same logic of collective pooling, long practised across the Black diaspora in the Caribbean, the Americas, and the continent itself. Today that instinct also flows through platforms such as the African Diaspora Investment Fund and the Ethiopian Diaspora Trust Fund.

Governments have tried to formalise this instinct into capital markets. Nigeria issued a US$300 million diaspora bond in 2017 at 5.625%, targeting Nigerians in the US, UK, and Europe. It was oversubscribed. Ethiopia raised more than US$50 million from its diaspora through an infrastructure bond tied to the Grand Ethiopian Renaissance Dam. But diaspora bond attempts by Ethiopia, Ghana, and Kenya on other occasions fell flat, undersubscribed by investors who did not trust the government issuing the paper. The lesson sits in plain sight: diaspora capital responds to transparency and credible governance, not sentiment. Nigeria’s bond worked because the terms were clear and the state made itself accountable to bondholders in a way it rarely is to citizens at home.

The toll on the money that already left

Here is where the story turns from generosity to extraction. Sub-Saharan Africa is the most expensive region in the world to send money to. In the first quarter of 2025, the average cost of sending US$200 into the region was 8.78% of the transaction, against a global average of 6.49%. Some corridors are far worse. Sending money from Tanzania has cost as much as 27% of the transfer. Nigeria, South Africa, and Angola have all posted costs above 14%.

That gap is a private toll. A concentrated market of money transfer operators and correspondent banks charges it, extracted from wages already earned and already taxed once in the country where the sender works. A nurse who sends home US$200 a month can lose the equivalent of two or three days’ wages a year just to fees. Multiply that across an estimated 170 million people of African descent living outside the continent, and the sums lost to transfer costs alone run into billions annually. This is Africa’s diaspora subsidising both African households and a global remittance industry at the same time.

From donor to decision-maker

The African Union recognised the diaspora as its Sixth Region in 2012, alongside North, South, East, West, and Central Africa. On paper, that recognition now carries institutional weight. Diaspora civil society organisations hold seats within ECOSOCC, the AU’s economic, social, and cultural council. A diaspora legal framework governs how they participate in AU policymaking. Ghana has gone further, granting dual citizenship to anyone of African descent and establishing a Diaspora Affairs Office to manage the relationship.

These are the building blocks of something more useful than another appeal for generosity. Africa does not need to ask its diaspora to give more. It needs to let the diaspora decide more.

That means three concrete shifts. First, push regulators and central banks to open remittance corridors to competition, the way Kenya’s mobile money ecosystem forced domestic transfer costs down. High fees are a policy choice, and policy can unmake them. Second, build diaspora bonds on Nigeria’s model rather than Ethiopia’s: real disclosure, real audit trails, real consequences for governments that mismanage the proceeds. Third, extend the Sixth Region logic from AU summits into the rooms that actually decide fiscal futures. Diaspora representatives already sit in ECOSOCC. They should sit in national budget consultations and sovereign debt restructuring talks too. Their money keeps those economies afloat. Their seat should follow.

The diaspora has been treated as a wallet for long enough. The money was always a form of power. It is time African states priced it, governed it, and answered to it as one.
