Editor's Letter

Who Sets the Terms

For a generation, the terms that governed African economies were written elsewhere and read here. In 2025 that arrangement cracked, in both directions at once.

Start with the letter that arrived in Maseru. In April 2025, from a podium in Washington, the American president declared a national emergency over the trade deficit and imposed what he called reciprocal tariffs on the world. Lesotho, a mountain kingdom of roughly two million people, was assigned a rate of 50 percent, the steepest levied on any nation on earth. A country most of the world could not place on a map had been handed the highest tariff in it. The terms of access to the largest consumer market on the planet had been rewritten overnight, for an economy that did nothing to invite it.

Now set beside it a second scene from later the same year. In November, heads of state landed in Johannesburg for the first G20 summit ever held on African soil, under a South African presidency that put debt, inequality and a fairer cost of capital at the centre of the agenda. The two most powerful leaders in the room stayed away. The meeting produced a leaders declaration regardless. For once the continent was not lobbying at the edge of the table. It was setting it.

2025 was the year the terms cracked in both directions. Africa was handed the worst of someone else's, and drafted more of its own than in any year this century.

Between those two scenes runs the argument of this issue. The old model had a single author. Trade preferences, aid budgets, the price of money and the rules of the digital economy were set in foreign capitals and delivered to African governments as weather, something to be endured or exploited but never negotiated. We have argued before that markets are made by whoever sets their rules, not by whoever trades in them, and 2025 was the year that question stopped being abstract. Our December brief on the global election supercycle called this the exposure that matters most, the settings reset abroad in the same window that decide more for the continent than any single vote cast on it. 2025 tested that thesis and mostly confirmed it. But it also showed the first serious counter current in years.

The counter current is visible in the numbers the African Development Bank presented in Abidjan on 30 March 2026. The continent grew 4.2 percent in 2025, up from 3.5 percent in 2024, and outpaced the 3.1 percent world average. Twelve of the twenty fastest growing economies on earth were African. Growth topped 5 percent in twenty two of them and 7 percent in six. Behind the average sits a spread wide enough to make the single continental figure close to meaningless: Ethiopia at 9.8 percent, Rwanda at 7.5 percent, Uganda at 6.4 percent, against oil economies barely moving. There is no African economy. There are more than fifty, running on different clocks.

The counter current is visible in money as well. After a two year freeze, African sovereigns walked back into international markets. Cote d'Ivoire opened in January 2025, Benin and Kenya followed, and by year end eight countries had raised 15.7 billion dollars across fourteen eurobond issues, up 15 percent on 2024, most of it oversubscribed. The S&P Africa Sovereign Bond Index returned more than 20 percent in the year to October and spreads narrowed to their tightest since 2019. The price of money is still set abroad. But in 2025, for the first time in a while, the market came back to Africa on improving terms, not punitive ones.

And it is visible in silicon. In the same twelve months, the physical layer of artificial intelligence began landing on the continent, no longer only rented from abroad. Google opened a cloud region in Johannesburg, Microsoft and G42 committed a billion dollars to Kenya, and Cassava Technologies signed a deal with Nvidia to build Africa's first AI factory, a 700 million dollar rollout beginning with 3,000 GPUs in South Africa and reaching 12,000 across five countries. Whether this becomes ownership or merely a better class of tenancy is the open question we return to later. But the machines are now here, with African addresses.

Hold the two scenes together and the shape of the year appears. Africa was on the receiving end of the harshest terms anyone imposed in 2025, and it authored more of its own terms than in any year this century. Both are true, in the same twelve months, and the tension between them is not a contradiction to be resolved. It is the condition to be managed.

Which brings us to the question this issue is organised around, and the one we would ask of any institution reading it at the start of a decisive year. Not whether the terms are fair, because they are not and were never going to be. The question is narrower and more useful: on the decisions that will actually shape the next ten years, whose terms are you accepting by default, and which ones could you be writing yourself?

Five Signals That Matter

The year, read against the grain

Five readings of 2025 and the quarter just closed, each chosen because it changes what an institution should do on Monday morning.

01

When a Mountain Kingdom Got the World's Highest Tariff

On 2 April 2025, from a podium he named Liberation Day, the American president declared a national emergency over the trade deficit and imposed reciprocal tariffs on much of the world. The rates were calculated from bilateral trade balances, which meant the smallest economies with the least to buy from America were hit hardest.

Lesotho, a landlocked kingdom of two million people, drew 50 percent, the highest rate assigned to any country. Madagascar took 47, Botswana 37, South Africa 30. Twenty African countries were targeted above the 10 percent baseline. For textile towns built entirely around duty free access to American shelves, the model that justified their existence was cancelled in an afternoon.

By August the picture had shifted again. Lesotho's rate was cut to 15 percent, the level most African nations settled at, while South Africa and the North African states stayed higher. Our January brief tracked how this became the trade weapon of the year, the moment comparative advantage stopped being the rule and access became a favour to be renegotiated.

A rate set from a spreadsheet in Washington rewrote the prospects of a factory town in the Maloti mountains.

02

The Money Came Back, and on Better Terms

For two years African sovereigns were frozen out of international debt markets by borrowing costs that touched the highest in the world. In 2025 the freeze ended. Cote d'Ivoire opened in January, Benin and Kenya followed within weeks, and the market stayed open all year.

By December, eight countries had raised 15.7 billion dollars across fourteen eurobond issues, up 15 percent on 2024, with Morocco's two billion dollar deal heavily oversubscribed. Yields on Kenya's 2028 note fell from 10.4 to 8.3 percent in a year. The S&P Africa Sovereign Bond Index returned over 20 percent to October, and spreads narrowed to their tightest since 2019.

The relief is real and the risk is the same as ever. Most of the proceeds refinanced maturing debt; little went to new capacity, and the price of money is still set by decisions taken in Washington and Frankfurt. But for the first time since the pandemic, the terms moved toward Africa, not away. And the eurobond market is not where most African capital actually moves: our May brief traced the fifty billion rand a year that flows through South African stokvels alone, a banking system with no licence and a lower default rate than most that hold one.

The price of money is still set abroad. In 2025 it moved toward Africa, not away.

03

There Is No African Economy. There Are Fifty.

The African Development Bank presented its numbers in Abidjan on 30 March 2026, and the headline was strong: 4.2 percent growth in 2025, up from 3.5 in 2024, comfortably above the 3.1 percent world average. Twelve of the world's twenty fastest growing economies were African.

The average is the least useful number in the report. East Africa led at 6.4 percent, carried by Ethiopia at 9.8, Rwanda at 7.5 and Uganda at 6.4, while oil exporters barely moved and a handful of economies shrank. Growth topped 5 percent in twenty two countries and 7 percent in six. Underneath it all, per capita growth reached just 1.9 percent, still short of the pace that moves poverty. The official figures also miss where most Africans actually earn: our July brief showed that close to nine in ten sub-Saharan workers trade in an informal economy our instruments were built to overlook, which means even the divergence on the chart understates the real one. Growth also has to outrun a fast-moving denominator: the demographic window we mapped in 2024 only pays off if jobs arrive faster than the working-age population does.

This is the pattern our systems work has returned to repeatedly: the continental frame hides more than it shows. Whether the unit is a country, a city or a sector, the meaningful variation in Africa sits below the level most analysis operates at. Anyone still allocating against a single African number in 2026 is pricing an average that describes almost no real place.

The Machines Arrived With African Addresses

For a decade the compute that ran African software sat on other continents. In 2025 that started to change in physical, visible ways. Google opened a cloud region in Johannesburg with a 148 million dollar commitment, and Microsoft with G42 put a billion dollars into a Kenyan cloud region and Swahili language models.

The signal event came from an African operator. Cassava Technologies, built by Strive Masiyiwa, signed with Nvidia to build the continent's first AI factory, a 700 million dollar rollout starting with 3,000 GPUs in South Africa and reaching 12,000 across Egypt, Nigeria, Kenya and Morocco. Unlike state led models elsewhere, it runs on private execution with an African firm holding the design.

The open question is ownership. Africa still holds roughly 1 percent of global AI data centre capacity, and South Africa's 56 data centres include only five that are AI capable. Our September brief framed exactly this trap: Africa keeps producing world class builders while other economies become the owners, and ownership is decided by where the value keeps compounding.

The GPUs are here now. Whether that becomes ownership or a better class of tenancy is still open.

A Seat at the Head of the Table

In November 2025, Johannesburg hosted the first G20 summit ever held on African soil, under a South African presidency themed on solidarity, equality and sustainability. It was the first summit since the African Union took a permanent G20 seat.

South Africa used the chair to push debt relief, a fairer cost of capital and inequality onto the core agenda, including a call for an intergovernmental panel on inequality modelled on the climate panel. The two most powerful leaders in the world stayed away, and the summit produced a leaders declaration regardless. The absence made the point as sharply as attendance would have.

Convening power is not the same as decision power, and a declaration is not a disbursement. But set against the tariff letter that opened the year, the symbolism holds. In the same twelve months, the continent was handed the harshest terms anyone imposed and drafted more of its own than in any year this century.

In one year Africa received the worst of someone else's terms and authored more of its own than in any year this century.

Key Takeaways

  • The organising fact of 2025 is that the terms cracked in both directions. Africa absorbed the harshest trade shock imposed on anyone, and authored more of its own agenda than in any recent year.
  • The Liberation Day tariffs made market access a live political variable. A 50 percent rate on Lesotho, later cut to 15, showed how fast the terms of trade can be rewritten and re-rewritten.
  • Capital returned. Eight sovereigns raised 15.7 billion dollars in eurobonds, spreads hit a post-2019 low, and the terms improved for the disciplined, where once they punished.
  • The 4.2 percent continental average is close to meaningless. Ethiopia grew 9.8 percent, oil economies barely moved, and per capita growth of 1.9 percent still trails what poverty reduction needs.
  • The physical layer of AI began landing, with Google's Johannesburg region and Cassava's 700 million dollar Nvidia AI factory. Africa still holds about 1 percent of global AI capacity.
  • The Johannesburg G20, the first on African soil, gave the continent the chair. Convening power is real; it is not yet decision power.

Anatomy of a Tariff Shock

How one line in an executive order travelled from a Washington podium to a factory floor in Maseru, and how the firms that survived had already built the exit. Read left to right.

The narrowing happens in the middle of the chain, not at the podium. The decree cost nothing to write and everything to absorb, because the firms carrying it had capital already committed to a single buyer.

02

The band widens again only where a second market existed before the tariff did. Optionality could not be bought once the order landed. It had to have been paid for earlier, which is the whole lesson of the year.

Three Charts Worth Studying

Three charts that reset the base case

Chart One

Five economies, one misleading average

The African Development Bank put 2025 growth at 4.2 percent for the continent. The figure is real and it is close to useless as a planning input. Ethiopia grew at 9.8 percent, Rwanda at 7.5, Uganda at 6.4, while oil exporters barely moved and a handful contracted. The average sits in empty space between them.

Why it matters. An allocator working from the continental number is pricing a country that does not exist. The spread between the fastest and slowest major economies is now roughly five to one, which means the correct question is never how Africa is doing. It is which Africa, on which clock, exposed to which shock. The single figure flatters the laggards and insults the leaders in the same breath.

Why it matters. The share stays near 3 percent, which makes the total the wrong object to watch. Concentration is the variable. That demand arrives in dense clusters, on specific substations, over a five year horizon, against grid assets that take a decade to build. A 3 percent national number can still be a 40 percent local one. Grid planning, not generation totals, is where this gets settled.

Chart Two

The window that reopened

After two years locked out by punishing yields, African sovereigns walked back into international debt markets in 2025. Issuance rose to 15.7 billion dollars across fourteen deals by eight countries, up 15 percent on the year before, and spreads narrowed to 388 basis points, the tightest since 2019.

Why it matters. Access to the eurobond market is a market verdict on credibility, and in 2025 the verdict improved. But most of the money rolled old debt forward; new capacity barely featured, and the coupons still cleared 8 percent. The window is open and it is not cheap. The countries that use it to buy time without buying reform will meet it again, on worse terms, at the maturity wall.

Why it matters. Semiconductor capital expenditure has always been a boom and bust industry that punished anyone who read a peak as a plateau. A five year ramp with a shallow 2028 pause has the profile of an infrastructure programme, because a meaningful share of it is underwritten by governments buying self sufficiency at close to any price. That changes who the marginal buyer is, and buyers with fiscal motives do not exit at the trough.

Chart Three

Four rates in five months

Lesotho began 2025 with duty free access to the United States under AGOA. On 2 April it was assigned 50 percent, the highest tariff in the world. Within days a 90 day pause dropped most rates to a 10 percent baseline. By August the kingdom settled at 15 percent, the level most of Africa landed on.

Why it matters. The final number matters less than the path to it. A factory owner cannot plan against a tariff that moves four times in five months, and orders cancelled during the 50 percent window do not return when the rate falls. The damage was done by the volatility, not the level. That is the real export of the year: not a rate, but the knowledge that the rate can change at any time.

Why it matters. A 4 percent economy growing against a 2.4 percent population is a respectable performance and nowhere near enough to move poverty at speed. The margin compounds slowly in the right direction and unforgivingly in the wrong one: a single point of growth lost to a tariff, a drought or a debt service payment takes almost half of it. This is the chart that makes the 1.3 trillion dollar financing gap a structural fact.

Books, Reports and Papers

Six documents that earned their weekend

Four reports and two of our own briefs. What each should change about the way you hold the year.

African Development Bank · Abidjan · 30 March 2026
The take

The definitive scorecard for the year: 4.2 percent growth, twelve of the world's twenty fastest economies, and a spread wide enough to retire the continental average as a planning tool. Read the regional decomposition, not the headline. The gap between East Africa and the oil exporters is the whole story.

Center for Strategic and International Studies · October 2025
The take

The clearest account of how the tariff shock and the lapse of AGOA collided with an administration that also wanted trade over aid. It holds the contradiction still long enough to see it. The takeaway for any exporter: American market access is now a domestic political variable, priced accordingly.

G20 South African Presidency · November 2025
The take

A 122-paragraph document is rarely worth reading in full; this one is worth reading for what it represents. The first leaders' declaration produced on African soil, with debt and the cost of capital near the centre. Convening power committed to paper. Whether it converts to disbursement is the test of 2026.

Africa Labour Research and Education Institute · 2025
The take

The most honest audit of the continental free trade area at five years: 35 countries piloting real trade, 2.3 million jobs linked to it, and a candid ledger of what has not moved. The gap between a signed protocol and a working customs post is where the next decade of intra-African trade will actually be decided.

December 2025 · Intelligence Brief · Diagelo
The take

Our own reading of the 2024 to 2025 election supercycle, when 1.6 billion people voted and Africa cast few of those ballots but lives with nearly all their consequences. The argument that framed this issue: the settings that matter most, trade, aid and the price of money, are reset in foreign capitals in the same window.

September 2025 · Systems Brief · Diagelo
The take

Why Africa keeps producing world-class builders and letting other economies become the owners. Read alongside the AI factory story in this issue: the machines arriving in Johannesburg and Nairobi are a test of exactly this thesis. Ownership is decided not at the departure gate but by where the value keeps compounding.

Revisiting Our Thinking

Marking Our Own Homework

Few institutions publicly audit their own published work. We intend to do it every quarter, on the record, including the parts that did not hold.

Diagelo Intelligence · published January 2026

The Tariff War Nobody Could Ignore

Revisited March 2026, against the first quarter of outcomes.
What held

We argued that Liberation Day marked the end of comparative advantage as the operating rule of trade, and that access to the American market had become a favour to be renegotiated, no longer a right. Nothing in the first quarter of 2026 softened that. AGOA lapsed, was restored on a one year horizon, and every African exporter now budgets for a market that can close by executive order. The direction was correct.

Where we were right

We wrote that the damage would come through volatility more than the headline rate, and that orders lost during the shock would not return when the number fell. Lesotho's rate moved from 50 to 10 to 15 percent inside five months. The factories that lost contracts during the 50 percent window did not get them back at 15. The mechanism worked exactly as described.

Where we were surprised

We underestimated substitution. We expected South African vehicle exports to fall with the loss of the American market. Exports to the United States did collapse, yet total vehicle exports reached a record, because alternative buyers had been cultivated in advance. We were right about the shock and wrong about the shock absorber, a lesson we have carried into this issue's fifth signal.

Key Takeaways

  • The thesis held on direction and mechanism: comparative advantage gave way to raw bargaining power, and volatility did more damage than the level.
  • The thesis missed adaptation speed. We priced the loss of a market and not the presence of alternatives already built.
  • The correction we carry forward: model the second door. Any forecast of a shock that ignores existing optionality will overstate the damage.
Questions We Are Watching

Six Questions We Are Holding

We publish the questions we cannot close. A question held honestly is worth more than a forecast held loosely.

01
Does an AI factory make an owner, or just a better tenant?
Watching: whether Cassava's GPUs anchor African-owned models and revenue, or simply host workloads priced and captured elsewhere.
02
Can South Africa convert the G20 chair into anything durable?
Watching: whether the Johannesburg declaration's debt and cost-of-capital commitments survive contact with a presidency that handed the gavel onward in December.
03
Is AGOA worth saving, or already a relic?
Watching: whether the one-year renewal is extended, and whether African exporters keep diversifying away from a US market that now resets its own terms annually.
04
Will the open eurobond window fund building, or just refinancing?
Watching: how much of 2026 issuance funds new capacity versus rolling old debt, and whether the maturity wall arrives before the reforms do.
05
Does AfCFTA move from pilot to plumbing?
Watching: whether the 35 Guided Trade countries turn published tariff books into working customs posts, and whether intra-African trade share finally moves off its floor.
06
Will allocators finally price more than one Africa?
Watching: whether the 4.2 percent average keeps anchoring capital decisions, or whether Ethiopia and the oil exporters start being underwritten as the different risks they are.
Retroactive relief does not rehire a shift.

Later this year · Foresight study

Terms are not weather.

For a long time they were treated that way here, something handed down from elsewhere, to be survived and never shaped. 2025 was the year that assumption stopped holding cleanly. A tariff arrived like weather, from a podium no African voter could reach. But a G20 was chaired, a free trade area kept building, and the first AI factories broke ground with local names on the deed.

The lesson of the year is not that Africa now sets its own terms. It plainly does not, on most of what matters. The lesson is narrower and more useful. The terms are more contested than they were, more of them are being written here than before, and the institutions that treat every rule as fixed will keep being surprised by the ones that move. Which of the four decade-trajectories we mapped last January Africa ends up on will be decided less by any single forecast than by who keeps drafting the terms, year after year, in rooms like the one in Johannesburg.

Our task is not to predict which terms will change. It is to know, at every moment, which ones you are accepting by default, and which ones you could be writing yourself.
