What African economies keep of the value they create, over the next decade.
South Africa runs the deepest capital market on the continent and one of the highest youth unemployment rates on record, 60.9% for those aged 15 to 24, a level no other major economy approaches. Both hold in the same country, in the same quarter. Read that as a working preview rather than a South African accident: an economy can assemble world-class financial plumbing and still fail to keep the dividend flowing underneath it, and the balance of payments is where you watch that failure happen.
One year of the labour market, on participation-adjusted figures rather than the working-age headline. The people who arrive do not vanish; they are absorbed, and the question is into what.
The thesis
You can read a decade of an economy's self-assessment in one line of its balance of payments, a line almost nobody outside a central bank ever looks at. The primary income account records what residents earn from the rest of the world against what the rest of the world earns from them, and across most of Africa it runs persistently, structurally negative: a measurable share of the value generated on the continent each year is booked as income to someone who does not live on it. That is the quiet fact this brief is built around, and it survives every argument about whether the continent is rising, because the rising is not in dispute. The harder question is what happens to the value once it is made, where it comes to rest, and whether the person who carried the risk to create it is paid back for having done so.
This brief models how demographic pressure, capital coherence and state capacity together determine how much of the value Africa creates between now and 2035 is retained on the continent rather than paid out.
So it treats Africa as what it is: 54 sovereign economies on different demographic clocks and governance trajectories, not one story with one verdict. The organising discipline of the whole piece is a single triage, running underneath every section. Separate what is locked in for the next decade from what is still contestable, and hold both apart from the handful of questions that remain wide open. Most outlooks blur the three, and the blur is where confident forecasts go wrong: a contestable trend treated as settled produces the kind of certainty that ages badly.
The young people who reach the labour market by 2035 are already born. Urbanisation momentum and mobile connectivity are similarly baked in. Arithmetic, not opinion, and the same across every section that follows.
Whether funding turns patient and locally anchored, whether currencies hold, whether states consolidate capacity rather than lose it. These move with policy and can break either way inside the decade.
The pace of AI and African-language tooling, AfCFTA's real depth, geopolitical alignment, the energy leapfrog. Unsettled, and the place where foresight actually earns its keep rather than restating the obvious.
Each section that follows sorts its own findings back into this triad. But the triad only says what is fixed and what is contestable; it does not say where a given economy is most exposed. For that the brief needs one instrument, and it is the frame everything else hangs on.
The framework
Four capabilities decide how much of the value an economy creates it manages to keep. They do not add. They multiply, so an economy keeps the product of the four and is held down by whichever one runs nearest to zero.
Same effort, spent two ways. The capability the economy is weakest at returns roughly 2.0× what the capability it is best at returns. Reform pays most where a country is worst, not where it is proud.
This is where the usual instinct fails. Development strategy is built to reward strength: find what a country does well and do more of it. Multiplication punishes that instinct, because capability added to a ring that is already strong barely moves a product a weak ring is holding down. The reform with the highest return therefore sits, almost always, in the capability an economy is worst at rather than the one it is best at. South Africa runs the most sophisticated capital market on the continent and a youth absorption rate near one in ten, and the arithmetic is blunt about which of those to work on.
The four sections that follow are the four rings, taken in order. Read each as an answer to one question: is this the ring holding the country down?
Every economy creates value and every economy loses some of it across its borders. The single-number version of that idea, a "capture ratio" quoted as so many cents on the rand, is easy to say and impossible to audit, and a figure a brief declines to compute has no business anchoring the brief. So this is the computed version. The naive proxy for it is already public and already comparable: the gap between gross national income and gross domestic product, read alongside the primary income outflows in the balance of payments. Both measure value created inside an economy that ends up accruing to non-residents, and both come straight from the national accounts rather than from anyone's model.
Used on their own, those two measures mislead, and in a direction that matters. Primary income outflows include the contracted, expected returns to foreign capital, the dividend an oil major earns on the field it financed, the coupon a lender is owed, so a resource economy such as Angola or Mozambique posts a very wide gap that reflects the deal it signed rather than value leaving unbidden. Rank those raw gaps as a capture league table and the rigour is manufactured, because the widest gaps would belong to the economies that imported the most capital to build the most, which is not the same as losing the most. The instrument here is a decomposition: three components reported side by side rather than pressed into one headline number.
Eight economies, latest available year. The tall bars belong to resource exporters, and are tall because of component (ii), not (iii). Select a bar for its breakdown.
Component (i) is compiled from IMF Balance of Payments Statistics and World Bank International Debt Statistics (primary income debits, latest available year, 2023–24); component (ii) is modelled as the stock of foreign-held equity and debt liabilities times a market-rate band; component (iii) is the residual. Figures are Diagelo estimates with wide error bars, not official statistics. Continental scale for (iii) is anchored to UNCTAD, Economic Development in Africa Report 2020 (illicit financial flows ~US$88.6bn/yr, ≈3.7% of Africa's GDP, concentrated in extractive commodities). Data as of 2023–24. Download workbook (CSV)
Component (ii) is the expected cost of imported capital, and calling it leakage in any normative sense would be wrong: an economy that brings in capital to build an LNG train has agreed to pay for it. The line between (ii) and (iii) is contested, because market rates have to be estimated and because some contracted structures are themselves how mispricing is dressed up as a legitimate fee. Stating that openly is what makes this an instrument rather than a rhetorical device, and the workbook is published so the split can be argued with rather than taken on trust.
Sub-Saharan Africa added 15.4 million people to its labour force in a single year, and it will keep adding on that scale for decades. The talent is real. Whether the economy absorbs it into something productive, or lets it spill into unemployment and migration, is the whole of the question.
The numbers usually quoted here are blunt, so be careful which one you are holding. Africa's working-age population sat near 750 million in 2019 and crosses 1.1 billion before 2035 (UN projections summarised by the EUISS, Reaping Africa's demographic dividend). On the widest horizon Africa accounts for essentially all net growth in the world's working-age population to 2050, because it is the only region whose working-age cohort is still expanding while everyone else's contracts (IZA/G²LM, The Demography of the Labor Force in Sub-Saharan Africa, drawing on UN World Population Prospects). Of total population growth to 2050 the continent's share is more than half, not the near-universal share sometimes claimed; the two figures get conflated, and the working-age one is larger.
What matters for a jobs argument is not the working-age headline but the labour force, and the two differ because not everyone of working age participates. This is the correction that sinks the widely-quoted "Africa needs 18 million jobs a year," which quietly swaps working-age growth for labour-force growth. On participation-adjusted figures the flow is roughly 15.4 million labour-force entrants a year, against which the ILO records 14.6 million jobs created, but close to nine in ten of the region's workers hold informal employment, so formal wage payrolls are absorbing only around 2 million of the arrivals (ILO, World Employment and Social Trends 2026, January 2026). The shortfall between 2 million and 15.4 million is the entrepreneurial frontier, and it is where the rest of this brief lives.
Two adjustments, working-age increase to labour-force entry to formal jobs. Per year, Sub-Saharan Africa, millions.

The headline numbers describe pressure, and pressure is not a payoff. Economists named this moment the "demographic dividend," a phrase that has misled a generation of planners because it makes a contingent thing sound automatic, as though the cheque clears the day the working-age share rises. It does not. The economy has to earn the dividend by putting each new worker somewhere more productive than the one before, and the historical record is unforgiving on this point: East Asia earned it between roughly 1965 and 1990 and bought the fastest sustained rise in living standards ever recorded, while the Arab world had the same youthful arithmetic in the 2000s, did not build the jobs to match, and got a youth bulge that came of age into unemployment and, in 2011, into the street. Sub-Saharan Africa now stands where both once stood, and which version it gets is settled at three gates that are, at present, all closing on it.
Labour has shifted out of agriculture into low-productivity services rather than industry. Total factor productivity has added roughly a quarter of a percentage point to annual growth across 25 years, and turned negative in commodity economies.
IMF, Regional Economic Outlook: SSA, 2026 · IGCSMEs are roughly 90% of businesses and about 38% of GDP, yet sit on a finance gap near US$330 billion, with around half of formal SMEs credit-constrained. Firms stay sub-scale and die young, so they never become employers.
IFC, MSME Finance Gap · DevelopmentAid, 2025Power, logistics and hard currency do not scale with the workforce. Load-shedding, border friction and thin FX cap how fast a firm can add a worker, so absorption meets a physical ceiling long before the labour does.
Energy · logistics · FX elasticityClose one gate and the dividend stalls, while the surge keeps arriving regardless. It is also why one demographic input produces four different outcomes downstream: the conversion happens only at the rate these three gates allow, and the rate is a policy variable rather than a constant.
The 2020–2022 venture boom is not returning at the same scale. What has emerged instead is more disciplined, more concentrated, and restructured around debt and local anchors. For a founder, that changes how you build.
The peak was 2022. The 2025 rebound is real but debt-led, not a return of equity exuberance. Data as of full-year 2025.

It is tempting to read the 2021 boom as the moment global investors finally believed in Africa. Sit with the capital flows and a less flattering story surfaces, because the boom was never really about Africa. It was about the price of money. With US rates near zero, capital hunted yield in places it would not normally underwrite, and African startups were one stop on that tour; when the Federal Reserve began raising rates in 2022 and a Treasury bill suddenly paid five percent for no risk and no currency exposure, the tourist capital went home. What stayed is more honest money. Equity has settled near US$2.4 billion while debt has climbed to a record US$1.64 billion, now 41% of all capital deployed (fundsforNGOs analysis of Partech data, February 2026). Debt has stopped being the awkward cousin of the cap table and turned structural.
And it lands in remarkably few places. Kenya, South Africa, Egypt and Nigeria, the Big Four, took roughly 72% of everything invested in 2025. Two readings compete and this brief will not pretend to settle them. One calls it healthy maturation, capital learning to price risk and pooling where it can; the other calls it the ecosystem narrowing, the gap between four gravity wells and the other fifty hardening into a chasm. Both are partly true, and to a founder outside those four markets it makes little practical difference. You build assuming the gravity rather than wishing it gone.
Share of total African tech funding. Data as of full-year 2025.
Kenya led on total (US$1.04B, debt-heavy); South Africa reclaimed the lead on equity and deal count (Partech / fundsforNGOs, 2026). CSV
Read the 2025 numbers as the output of an allocation function whose inputs all changed together. When global rates rose, the growth-at-any-cost equity that chased African startups in 2021 found cheaper, safer homes and left, so what stayed demanded a path to cash. A dollar investor in a naira or cedi company prices in the currency's swing, which lifts the return hurdle and pushes capital toward instruments that self-protect, which is what debt does. Thin IPO and M&A markets mean equity cannot reliably exit, so it either stays away or returns structured as debt. And the markets with local pension pools, working courts and deeper FX (the Big Four again) can underwrite all three risks at once, so capital gathers where it can be priced.
So debt at 41% of deployment and the Big Four at 72% are one finding rather than two: capital is re-anchoring wherever risk can be measured and recovered. Which tells a founder what to optimise for. The work this decade is to make the business legible and recoverable, through local revenue, hard collateral or verified cash flows, because a growth story pitched at the equity that has gone home is the wrong message for the capital that is actually in the room.
Through the 2000s and 2010s, development policy chased a tidy dream: turn informal traders into tax-registered firms. It mostly failed. The breakthrough came from somewhere nobody was watching. In 2007 a Kenyan operator, Safaricom, launched a service to help people repay small loans by phone; customers ignored the instructions and used it to send each other money, for school fees, funerals and stock. Safaricom rebuilt the product around what people were actually doing, M-Pesa became the rails the banks had never bothered to lay, and the informal economy has been riding them since.
Mobile-money figures are for Sub-Saharan Africa as the denominator against a global total: GSMA, State of the Industry Report on Mobile Money 2026 (2025 data; global value passed US$2 trillion in 2025) and SOTIR 2025 (2024 accounts). Remittances: ISS Africa, 2024. Data as of 2024–25.
Informal employment will still sit above 70% across much of the continent in 2035, which is close to locked in. But the frame of "formal good, informal bad" misreads the opportunity. A spaza shop reconciling its day in a wallet app, a market trader taking a QR payment, a boda rider building a repayment history through transaction data: none of these is formal in the tax sense, and all of them are now legible. Legibility is what unlocks credit, insurance and inventory finance, and it is arriving without a single registration form. The informal economy did not need formalising. It needed a phone number, and it got one.
The numbers reward a second look. In 2024 the headline read that FDI into Africa, about US$97 billion, had finally drawn level with diaspora remittances of roughly US$95 billion. Then you read the footnote. More than a third of that FDI was a single transaction: a roughly US$35 billion deal in which an Abu Dhabi fund bought the right to develop Ras El-Hekma, a stretch of Egyptian coast on the Mediterranean. Strip out that one cheque and real, diffused investment across 54 economies drops to around US$62 billion, below what migrants wire home, now 5.1% of the continent's GDP (ISS Africa, 2025). The largest external financial flow into Africa comes not from investors or aid agencies but from the diaspora, and most of it is spent rather than invested. The unbuilt rail of the decade turns even a slice of that flow into patient, diaspora-anchored capital.
Stable diaspora flows now exceed foreign direct investment once the year's one megaproject is removed. Data as of 2024.
For years the effort ran one way: drag the trader into the bank. What actually happened ran the other. The bank is being taken apart into its functions and reassembled on rails the informal economy already runs on. More than 350 million adults in the region have no bank record, yet a market trader now emits a continuous, machine-readable cash-flow signal through wallet turnover, airtime, utility and e-commerce activity, which lenders read to price risk where they once saw a blank. What is assembling itself, layer by layer, is a credit stack built against the roughly US$330 billion the formal system never lent.
Each layer turns the one below it into capital. Legibility compounds upward; the top layer is the decade's largest unbuilt opportunity. Layer heights are illustrative, not quantitative.

The African Continental Free Trade Area is the most ambitious integration project the continent has attempted, and its progress is real but partial. Intra-African trade sits near 16% of total trade, up from under 10% two decades ago, with formally recorded flows rising from 13.6% in 2022 to 14.9% in 2023 (Afreximbank Trade Report, via Brookings). That figure measures what clears customs. The small-scale cross-border trade running through the same informal channels this brief keeps returning to, traders moving goods by minibus and mobile money, adds to it, and at specific borders rivals or exceeds the recorded flow, most visibly in the Great Lakes corridors between the DRC and its eastern neighbours, and along Nigeria's western borders with Benin and Niger.
How much informal trade adds is where the honesty has to be careful. A widely repeated claim puts the true figure "closer to 40%" once informal flows are counted; that number is not traceable to a single study or method. The defensible statement is 16% formally recorded, with informal flows adding materially at particular borders rather than doubling the continental figure. The companion Diagelo brief on intra-African trade builds on the same 16% baseline, and this brief adopts it too. The distinction changes what AfCFTA has to do: less to invent African trade than to see, formalise and finance the trade already moving.
Ambition keeps outrunning implementation. The African Union's own 2025 integration review put it plainly: without implementation, regional frameworks remain promises on paper. The World Bank's modelling shows intra-African exports reaching only about 15% by 2035 on the current path, rising to roughly 21% if AfCFTA's measures advance together. The 25-to-30% figure some cite requires payment integration, tariff harmonisation and non-tariff barrier reduction to move in lockstep, and they rarely do.
The early winners show the shape of it. Under AfCFTA's guided-trade pilot Rwanda began shipping packaged coffee to Ghana, then widened the corridor to tea, avocado oil and honey: finished goods moving between two African markets rather than raw beans bound for Europe. That is the promise in miniature, one corridor deep, not continent-wide. If you build in cross-border logistics, payments or manufacturing, AfCFTA is a tailwind or a mirage depending on which protocols have ratified in your lane. The corridor, not the continent, is the unit of planning.

"Paper versus real" is the wrong axis for this. Integration fails in three distinct places, and a different one binds in every corridor, so the question is never whether AfCFTA is working in general but which of these three is the one actually stopping the goods in the lane you care about.
Tariff schedules, rules of origin and the paperwork that decides whether a good qualifies as "made in Africa" at all. The tariff lines are being agreed; the rules of origin and standards behind them lag.
Roads, ports, border posts and the dwell time a truck spends waiting. A zero tariff means nothing if a container sits at the border for a week or the road does not exist.
Cross-border payment and FX conversion. Two African firms still often settle through a dollar or euro leg. PAPSS, the continental payment system, is the lever here, and its real adoption is the variable to watch.
A continental average is useless for planning, because AfCFTA does not advance or stall as a whole. It clears one friction in one corridor at a time. Map your corridor against these three, find the binding one, and the real entry timeline follows from that rather than from the headline.
Each path is rooted in conditions you can observe now, and each carries different implications for governments, investors and founders. But economies do not sit inside these boxes and stay there. They move through the field, and the movement is the investable fact.
Local pension and sovereign capital anchor a blended funding stack. Digital public infrastructure lowers the cost of starting a legible business, energy build-out de-bottlenecks light industry, and excellence stops being enclave-bound and reaches second cities.
Capital is disciplined and well-governed, but it pools in a few cities and sectors. World-class companies sit beside a deepening youth crisis. The South Africa pattern written continent-wide, and the realistic default rather than the worst case. The risk here is social, not financial.
High nominal activity on fragmented, foreign-dominated capital. It looks like a dividend captured, and it is not one: currencies swing, ownership sits abroad, and the abundance is usually a commodity boom that accrues elsewhere. Economies do not rest here. They drift down into the Missed Window, which is why this quadrant is close to empty and why the two axes are not independent.
Capital is volatile and siloed, governance backslides, and the dividend pressures into unemployment, migration and instability. The consequences run well past 2035, because the cohort that needed absorbing this decade does not get a second one.
Two of these four quadrants are not equally reachable, because capture tends to follow coherence. Brilliant Pockets, coherent capital that captures value but only in enclaves, is the crowded default. Volatile Abundance, fragmented capital that nonetheless keeps a broad dividend, is close to empty, since a dividend booked on foreign-owned, currency-exposed capital is not retained for long. This brief leaves that quadrant visibly thin rather than pretend the two axes are orthogonal, and the drift map below has no economy resting inside it. That absence is the point, not a gap in the data.
Most scenario work treats these as four bins economies are sorted into and left. They are regions of one field, and the forces that place a country also push it: a currency shock can slide an economy from Brilliant Pockets toward the Missed Window in a single year, while a serious capital-anchoring reform lifts it the other way. Most economies are mid-transition, holding a hybrid position, drifting. The map below plots nine of them, and does what a scenario grid cannot: it shows where each sits today and where each sat five years ago, so the vector is measured rather than asserted.
Figure 07Position is today's balance of coherence and capture; the arrow is the likely direction of travel on current policy. Solid is the probable path, dashed is contingent on a single decision.
The investment implication is that you are not betting on a country's position but on its vector: which way it is moving, how fast, and what single decision would flip the sign. What follows is that list of sign-flipping decisions, stripped of any framework and left as what it is, a set of choices with dates attached.
A preview rather than a special case. It reached the future first, deep capital markets bolted onto an economy that cannot absorb its own young people, and it shows the rest of the continent which tension ships next if the engine is left on its current settings.
In Tembisa, a stokvel of twelve women runs a buying group that would make a procurement director jealous. They pool cash weekly, settle on a phone, negotiate bulk prices a formal retailer cannot match, and extend informal credit on trust built over years. Not one of them appears in a startup database. Every one of them is an entrepreneur, and most have been unemployed in the official sense for longer than the data cares to admit.
This is the country that, in 2025, reclaimed the African lead in startup equity funding and deal count, with the continent's deepest capital market and most mature venture scene. It also carries youth unemployment of 60.9% for those aged 15 to 24, a youth absorption rate of just 10.1% so that barely one working-age young person in ten holds a job at all, and graduate youth unemployment of 23.9%, which means even a degree leaves nearly a quarter of young graduates without work (Stats SA, Quarterly Labour Force Survey, Q1 2026). Brilliant pockets, broad stagnation. The trajectory has a name because South Africa already lives inside it.

The system, mapped
Fifteen years reading these markets has taught one stubborn lesson: capable investors keep mistaking the depth of Johannesburg's financial plumbing for the health of the economy beneath it. The plumbing is world-class. Below it sit two economies, and the second one, younger and larger and entrepreneurial out of necessity, is almost entirely uncapitalised. Yet the money to change that is already in the country. South African pension and retirement funds hold several trillion rand, and for years Regulation 28, the prudential rule governing how those funds may be allocated, kept the bulk of it in listed equities and bonds, well away from the township firms and infrastructure that would move the absorption rate. Recent amendments to Regulation 28 have begun to loosen that. Route even a sliver toward the second economy, on rails it already trusts, and the split starts to close. The reflex to formalise the informal sector before funding it has the sequence backwards; fund it where it stands.
South Africa's question is every African economy's question, only arriving earlier: who the money reaches.
These are the decisions the drift map turns on, the ones that move a country from one region of the field toward another. They are not ranked into tiers, because the sequencing is contested and a false hierarchy would only hide that. What is not contested is that each has a window, each closes, and most are made by regulators and states rather than by founders.
Whether pension funds and sovereign vehicles are allowed and incentivised to back African venture and credit at scale. The biggest single swing on the coherence axis, and the upstream lever that pulls the others with it.
National identity, payments and data rails owned domestically lower the cost of starting a legible business and feed the credit stack directly. Rwanda, Ethiopia, Egypt and Nigeria are moving; the sovereignty premium compounds.
Payments interoperability, free movement, non-tariff barrier reduction. The corridors where these land become the real single market; map your corridor against the three frictions and the binding one is your timeline.
Diaspora bonds, lower transfer costs, productive instruments. This is Layer 4 of the credit stack; a fraction of US$95 billion redirected from consumption to enterprise reshapes the funding stack from the top down.
Distributed renewables plus storage can power SMEs faster than grid expansion in most peri-urban and rural contexts. This is the third structural gate from Section I, and the financing model is the bottleneck rather than the technology.
African-language tooling and local compute, or dependence on rented foreign models. An open question today, close to locked by 2032. Cheap to influence now, expensive to reverse later.
Whether Kigali, Accra, Casablanca, Dakar, Kampala and Cape Town absorb the next tier of growth, or the Big Four widen their lead and the divergence hardens into structure.
Women founders, rural enterprise, youth without tertiary education, displaced populations. Whether these cohorts are brought in or left behind decides whether the dividend is captured at all, or only in pockets.
The same six economies, read against six constraints. The colour is the severity, and each cell names both the mechanism behind it and the source the rating draws on. Hover or focus any cell for the detail. The binding constraint, not the average, is what you plan around.

Start the accounting from the balance-of-payments line this brief opened on, and one number governs everything downstream: how much of the value created on the continent is retained by the people who created it. That retention behaves less like the sum of four independent inputs than like their product. Demographic pressure sets the potential, the capital structure decides who owns the upside, the rails decide whether value is legible enough to bank, and the trade market decides what it can be sold into, and because these terms multiply rather than add, the outcome is governed by the weakest of them.
Michael Kremer formalised this structure in his O-ring theory of development, which models production as a chain of tasks whose qualities multiply rather than sum, so that a small failure in any single task sharply degrades the value of the whole (Kremer, "The O-Ring Theory of Economic Development," Quarterly Journal of Economics, 1993). The theory is named for the component that destroyed a space shuttle: everything else worked, one part did not, and multiplication did the rest. An economy with a powerful demographic engine, world-class fintech rails and a signed trade agreement, but with capital that captures the upside offshore, does not score three out of four. It is capped by the term nearest zero, and the other three cannot compensate.
Which reframes the decade's work. It is not to maximise any single input, because a brilliant score on demography or on digital rails is wasted against a weak link elsewhere. It is to find the binding ring in each economy, the one nearest zero, and raise it. That is what the Retention Chain measures, and what the constraints map, drift map and capture decomposition feed. Growth was the settled question, and it is settled. Retention is the open one, decided term by term, economy by economy, at the weakest link in each.
Stop asking whether Africa will grow. Ask what it keeps.
The value of a brief like this lies less in the prediction than in the decision it sharpens. Diagelo works with a small number of investors, operators and institutions to turn a continental read into a specific position: which corridor, which constraint, which vector, which year. If the drift map raised a question about a market you are already in, that is the conversation to have.
This document is analysis, not investment advice. Figures marked as Diagelo estimates are modelled, carry wide error bars, and are published with their workbooks so they can be checked and argued with.
Version 2.0 (February 2026). This revision re-dates the brief to February 2026, re-sources every load-bearing figure to material predating that date, reduces the analytical frameworks from eight to four, rebuilds the capture metric as a published three-part decomposition, and corrects the population-growth, intra-African-trade and mobile-money figures. A full change log is maintained at the corrections link above.
