Potential long-run loss to global output under deep fragmentation, per the IMF, about $7.4 trillion
When trade became a geopolitical weapon, Africa’s choices changed.
In the same season of 2025, two letters travelled between Africa and Washington. One arrived in Maseru: a notice that goods from Lesotho, a mountain kingdom of roughly two million people, would face a fifty percent tariff, the steepest rate applied to any nation on earth. The other left Kinshasa: a handwritten appeal from a president under military pressure, offering the United States access to the cobalt and copper beneath his country in exchange for security. Same trading system, same year, opposite ends of the same weapon.
For most of two generations, economists taught that trade rewarded efficiency. A country made what it made cheaply, sold it abroad, and bought what others made cheaply in return. David Ricardo called the underlying logic comparative advantage, and the institutions built after 1945, the GATT and later the World Trade Organization, encoded it into rules meant to keep politics out of commerce. The promise was that goods would follow prices, not flags.
That order did not end with a treaty. It ended with a tariff schedule. On April 2025, in a ceremony he named Liberation Day, the American president declared a national emergency over the trade deficit and, invoking emergency economic powers, imposed a ten percent duty on nearly all imports with far higher rates on dozens of trading partners. The rates were not calibrated to any foreign tariff. External analysts quickly showed they tracked one number: the size of America’s bilateral goods deficit with each country, divided and halved. A formula that had nothing to do with what anyone charged the United States, and everything to do with leverage.
Trade stopped being a market and became an instrument. The question this poses for Africa is unavoidable: what happens to a continent when access to markets, capital and technology is governed by national security rather than comparative advantage?
The story runs deeper than one administration or one set of tariffs, several of which were later suspended, exempted or struck down in the courts. It describes a structural shift that predates 2025 and will outlast it. The pandemic, the war in Ukraine, the semiconductor contest and the scramble for the minerals behind artificial intelligence have each pushed governments to prize resilience over price. The International Monetary Fund has a name for it: geoeconomic fragmentation, the policy-driven reversal of decades of integration. Its economists estimate a deeply fragmented world could shed as much as seven percent of global output over time, close to seven and a half trillion dollars.
Africa did not choose this contest. It is being conscripted into it. And as the two letters of 2025 show, the continent enters holding the weapon at both ends: acutely exposed where it sells finished goods into distant markets, quietly indispensable where it sits on the minerals the great powers now regard as matters of survival. That dual position is the subject of this brief. How it formed, how four other emerging economies have played comparable hands, and how a leader can tell which end of the weapon a country is holding.
The world did not stop trading. Measured crudely, globalisation looks intact: the ratio of goods trade to global output has hovered between forty-one and forty-eight percent since the financial crisis. But beneath that stable surface, the direction of trade is bending along political lines. American imports from China fell by roughly a third between 2024 and 2025. China’s share of United States imports had already dropped eight percentage points between 2017 and 2023. Flows are being redrawn not by cost but by alliance.
Fragmentation bites harder now than during the Cold War for one reason: scale. As the IMF’s Gita Gopinath has argued, the same cut inflicts far more pain on a world this interwoven, and the pain lands unevenly. The Fund’s modelling finds low-income countries would lose more than four percent of GDP permanently under a severe split into blocs, a pandemic-scale shock that does not reverse.
There is a subtler point buried in that modelling, and it is the one that matters most for African capitals. In a fragmented system, the countries that suffer least are not the richest but the least substitutable and the least dependent. A supplier the great powers cannot easily replace holds leverage. A supplier whose sales run through a single revocable channel holds none. Comparative advantage measured how efficiently you produced. The new order measures something colder: how hard you are to do without, and how badly you need the other side. Efficiency has been demoted. Position has been promoted.
Non-aligned states have so far cushioned the system, acting as connectors that keep goods moving between blocs that no longer trade directly. That role has value, and Africa is well placed to play it. But the connectors are only useful while the walls are low. As the weapon is used more freely, the space to sit comfortably between camps narrows, and every government is pressed to answer a question it once could ignore: whose side is your supply chain on?
The Liberation Day schedule read, for African officials, like a document written about them without their participation. Lesotho, singled out from the podium as a country “nobody has heard of,” drew fifty percent. Madagascar, one of the world’s poorest nations, drew forty-seven. Across Southern Africa the rates clustered high: Mauritius at forty, Botswana at thirty-seven, Angola at thirty-two, South Africa at thirty. As the CNN tally noted, several of the hardest-hit economies rank among the twenty-six poorest on the planet, together responsible for half a percent of global output yet home to nearly forty percent of the world’s poor.
The map below shows the reciprocal rates announced against African economies. The pattern is not one of hostility so much as indifference: rates rose with the bilateral trade surplus a country happened to run with the United States, which is why textile and apparel exporters were punished while raw-commodity shippers, whose goods already entered at low duties, were largely spared.
A tariff is a shock. The withdrawal of a preference is a structural change, and Africa absorbed both at once. On September 2025, the African Growth and Opportunity Act, the twenty-five-year arrangement that granted thirty-two sub-Saharan economies duty-free access to the American market for thousands of products, expired without renewal. For a moment the United States became the only major economy with no formal trade programme in sub-Saharan Africa. Congress later stitched a one-year extension into an appropriations bill, reauthorising the act through December 2026 and restoring benefits retroactively. The reprieve was real. So was the lesson.
The numbers explain why the lapse frightened trade ministries from Nairobi to Maseru. Kenya grew apparel exports to the United States from about fifty million dollars at the programme’s start to roughly five hundred million; one Nairobi factory owner said that without the preference there was “zero chance” of competing with Asia. In Lesotho, AGOA apparel supports thirty to forty thousand jobs, most held by women, where roughly a third of exports depend on it. For South Africa, the largest beneficiary, vehicles and parts made up sixty-four percent of AGOA-eligible exports. UNCTAD calculated that without renewal, Kenya’s trade-weighted US tariff would nearly triple, from ten to twenty-eight percent.
Set beside the countries that policymakers reach for as alternatives, the ranking looks almost designed to redirect production. A shirt sewn in Lesotho met a fifty percent wall. The same shirt sewn in Vietnam met twenty. Mexico, inside a rules-based agreement, met effectively zero on qualifying goods. For a buyer deciding where to place next season’s order, the tariff schedule was a map to the exit, and it did not point toward Africa. This is what it means for trade to become a weapon: the damage falls not on the least efficient producer but on the most replaceable and the most dependent.
Because the formula keyed on trade surpluses, the countries punished hardest were the ones that had done what every development textbook prescribes: moved beyond raw commodities into making things. Lesotho, Madagascar and Mauritius earned their steep rates precisely because they had built garment and textile industries. The raw-cobalt and crude-oil shippers, still at the bottom of the value chain, drew the baseline ten. Read plainly, the 2025 schedule was a tax on having industrialised, levied heaviest on the exact behaviour African policy has spent forty years trying to encourage.
The second letter, the one from Kinshasa, carries the weapon’s reverse edge. In February 2025, as a rebel offensive seized cities in the eastern Democratic Republic of Congo, President Tshisekedi wrote to Washington offering American access to Congolese minerals in exchange for security. The United States brokered the Washington Accords between the DRC and Rwanda, and by December 2025 had signed a Strategic Partnership Agreement granting American buyers preferential access, establishing a coordinated minerals reserve, and requiring Kinshasa to notify Washington before changing its cobalt export policy.
Why this urgency over one African country’s geology? Because the minerals that make electric vehicles, missiles and artificial-intelligence data centres run overwhelmingly through African soil, and their supply is dangerously concentrated. The DRC holds roughly seventy percent of the world’s cobalt reserves. And the processing that turns ore into usable material is more concentrated still, held not in Africa but in China.
This is the paradox at the heart of Africa’s position. The continent is not peripheral to the twenty-first-century economy; it is foundational to it. Yet holding the reserve is not the same as holding the leverage. The DRC ships cobalt hydroxide abroad to be refined, where the profit accrues and the product is finished. Its indispensability is real but hostage to a single processing partner and, until recently, a single route. Washington understood this, which is why the December agreement paired mineral access with the Lobito Corridor, a rail line steering Congolese copper and cobalt west toward the Atlantic and away from Chinese-controlled channels.
A reserve you cannot refine is a resource. A resource you can refine, and route, and withhold, is leverage. The distance between the two is the whole of industrial policy.
By February 2026 the contest had acquired institutions. The United States convened its first Critical Minerals Ministerial, launched a twelve-billion-dollar mineral stockpile it named Project Vault, and invited resource-rich states to form a preferential bloc with coordinated price floors. This is trade recast entirely as statecraft: not a market clearing at a price, but a club admitting members. Africa holds the entry ticket for cobalt, copper, manganese and the rare earths. The unsettled question is whether it enters as a shareholder or as a supplier, and that question, it turns out, has a structure.
In a market, a relationship is priced. In a weaponised system, it must be booked, on two sides of a ledger. Every economic tie a country holds carries an entry on each side: indispensability, the cost to the other party of doing without you, and dependence, the cost to you of losing them. The first is the leverage you hold. The second is the leverage held over you. A nation’s true position is the balance across all its relationships, and that balance, not the size of its economy, decides how a weapon of trade will treat it.
Plot the two against each other and four positions appear. They are not permanent addresses. They are locations a country can move through, and the direction of travel is the entire content of a modern industrial policy. Select a case to read its position.
The framework’s sharpest claim is about targeting. A weapon of trade does not strike the strong; it strikes the exposed. It hits the Tributary, the producer who is both replaceable and dependent, because that is where pressure converts cleanly into compliance and where retaliation costs the aggressor nothing. Lesotho’s apparel sector, brilliant at sewing but reliant on a single preferential channel it did not control, was a Tributary, and the fifty percent rate found it exactly. The DRC’s cobalt is a Fulcrum, indispensable enough to summon a presidential agreement, dependent enough that the agreement was written largely on someone else’s terms.
If coercion targets the lower-right, then survival means leaving it, and there are only two exits. Move up, and raise your indispensability by capturing more of the value chain at home, the path Indonesia took with nickel. Move right to left, and cut your dependence by spreading your sales, your suppliers and your routes across many partners, the path a continental market makes possible. Everything that follows is a study of who has taken which exit, and at what cost.
No African economy has to invent its response from scratch. Four emerging economies have already played strong and weak hands in the weaponised system, and each shows one exit from the Tributary, along with its price.
Indonesia sat on the world’s largest nickel reserves and shipped them raw for decades. In 2020 it banned raw exports, forcing anyone who wanted the metal to refine it on Indonesian soil. Export value roughly quintupled, from about six billion dollars in 2013 to nearly thirty by 2022. It climbed the ledger toward real indispensability. The catch hides in the same move: the refineries are Chinese-built and Chinese-run, the buyer of last resort is still China, and the WTO ruled the ban illegal. Kinshasa, which has studied this playbook for its own cobalt, should read both halves.
Mexico’s exports are eminently replaceable, yet it did what few captured economies manage: it made its dependence hard to weaponise by writing it into rules. Under USMCA, goods that meet regional-content thresholds enter the United States effectively duty-free, and when blanket tariffs loomed in 2025 firms scrambled to qualify, lifting compliance from forty-five to eighty-nine percent in a year. Proximity plus a binding treaty became a shield. Its flaw is that the shield lasts only as long as the treaty, and a 2026 review now hangs over every plant.
Vietnam built the archetypal China-plus-one economy, absorbing work that firms wanted out of China and reaching one hundred and sixty-five billion dollars in electronics exports. It cut everyone’s dependence by offering a second address. Then the weapon found the ceiling: the 2025 framework set a twenty percent tariff and a forty percent duty on transshipped goods, aimed at Chinese parts merely passing through. A corridor that only relabels is itself replaceable.
India held to autonomy, refusing to pick a bloc while courting the factories fleeing China, and now assembles roughly a quarter of the world’s iPhones. Autonomy is not free. When it kept buying discounted Russian oil, Washington stacked on a penalty that pushed its rate to fifty percent, among the harshest on any large economy, before rolling it back once Indian buyers adjusted. Scale bought room to absorb and negotiate. The lesson for smaller states is unforgiving: non-alignment is leverage only if you are costly to punish.
Read together, the four hold a single message. There is no clean escape from a weaponised system, only better and worse positions within it. Indonesia bought power at the cost of a new dependence. Mexico bought security at the cost of a review clause. Vietnam bought relevance until the rules caught its shortcut. India bought room by being too big to bully cheaply. For most African economies, individually too small to deter and too specialised to be indispensable, none of these hands is playable alone. Which is precisely the argument for not playing alone.
Africa’s two exits from the Tributary map onto two instruments the continent already possesses, one for each axis of the ledger. To reduce dependence, deepen the internal market. To raise indispensability, keep more of the mineral value chain at home. Neither is theoretical. Both are underway, and both are moving too slowly.
The single most striking fact about African trade is how little of it is African. Intra-African trade sits at roughly fifteen to eighteen percent of the total, against nearly sixty percent in Asia and around seventy in Europe. Every point of that gap is dependence on distant markets that can, as 2025 proved, revoke access at will. The African Continental Free Trade Area is the mechanism built to close it: a single market of 1.4 billion people, forty-eight ratifying states, and agreed tariff schedules on more than ninety percent of goods. Trade under its rules has begun, and the World Bank projects full implementation could lift fifty million people out of extreme poverty by 2035.
A larger internal market does more than add sales. It changes a country’s position on the ledger. An apparel maker selling only to the United States is a Tributary; the same maker selling across a functioning continental market, with the United States as one buyer among many, becomes a Skiff, replaceable still but no longer captured. The obstacles are not secret: infrastructure gaps, a trade-finance shortfall estimated near one hundred billion dollars, unresolved rules of origin on the very sectors, autos and textiles, that matter most for industrialisation. But these are problems of implementation, not of design, and implementation is a choice.
The mineral wealth that summons presidential agreements will not, on its own, make Africa indispensable, because indispensability lives in processing, not extraction. The continent holding seventy percent of the cobalt captures almost none of the margin on the battery. Closing that gap is the second exit, and governments are reaching for it unevenly: the DRC has tested export quotas and beneficiation rules, and mineral-rich states have studied Indonesia’s downstreaming. Indonesia also supplies the caution for free. Forcing refining onshore captures value but can relocate the dependence, trading a foreign buyer for a foreign operator. Extraction with one customer is a Fulcrum. Processing with many is an Anchor.
Between the two axes lies a diplomatic stance. The great powers are building competing clubs, an American minerals bloc, Chinese processing dominance, a European push for its own raw-materials security. A continent that must pick one loses the leverage of being wanted by all. The connector role that has cushioned the wider system is available to Africa on better terms than to most, precisely because its minerals are courted from every direction. The discipline required is to convert that courtship into competitive bids rather than exclusive dependence: to run the DRC’s cobalt, Zambia’s copper and South Africa’s platinum as auctions among rival buyers, not as tribute to a single patron.
The two letters close the argument where they opened it. Maseru’s and Kinshasa’s arrived in the same system in the same year, and everything separating their fortunes is captured in the ledger. Lesotho sold a replaceable good through a channel it did not own, and the weapon found it. The DRC held something the world could not do without, and the weapon negotiated with it. Neither position was destiny. Lesotho’s apparel could anchor a regional garment market in place of a single foreign one. The DRC’s cobalt could be refined and owned at home, not merely dug and shipped. The difference between the two futures is not luck or geology. It is the deliberate work of moving on the ledger, up toward indispensability, across toward diversity, and out of the one corner where a weapon of trade does its cleanest work.
Africa remains the most forecast and least decided continent on earth. Every institution with a model has projected its trajectory; almost none of those trajectories have been chosen by Africans deciding, deliberately, which end of the weapon to hold. The tariff war of 2025 did not create Africa’s exposure. It made the exposure legible, and with it the choice. A weapon, after all, is only dangerous depending on which hand is on the grip.
Tariffs make news; the reordering underneath makes the decade. Global trade is re-pricing from efficiency toward security, and the change outlasts any one dispute.
The durable lesson sits under the tariff: the ground rules of exchange are being rewritten toward resilience, and a producer's map of destinations now carries as much weight as its cost base.
