For half a century, Botswana’s diamonds appeared to grant the country a quiet immunity from economic gravity. The stones vaulted a thinly populated republic into the front rank of Africa’s most prosperous and stable states, paved its roads, filled its classrooms, and turned a state partnership with De Beers into one of the continent’s most consequential commercial marriages. Then the market that had underwritten all of it faltered.
Prices softened. Inventories swelled. Government coffers thinned. In 2024 the economy contracted by 3 percent, a reversal traced almost entirely to the downturn in the trade that had made the country’s fortune. Now Botswana is attempting the feat that resource-rich nations habitually vow and seldom accomplish: to spend the proceeds of a single dominant commodity building an economy that will no longer bow to it.
At the fulcrum of that ambition stands Dr. Akinwumi Adesina, the former president of the African Development Bank, who has assumed command of the Diamonds for Development Fund with an unusually unvarnished promise. The fund, he has said, will marshal serious capital for diversification, exports and jobs – but it will not bankroll “Mickey Mouse projects.”
That single line may be the most illuminating thing yet uttered about the fund’s emerging creed. Botswana is no stranger to diversification schemes, development agencies or state-backed finance. For years its leaders have sought to broaden the economy beyond mining, naming agriculture, tourism, manufacturing, financial services and technology as candidate engines of growth. Progress has been fitful, and the enduring gravitational pull of diamonds has left the country hostage to forces well beyond its borders: consumer appetite in the United States and China, the encroachment of laboratory-grown stones, the inventory calculations of global jewelers and the mercurial economics of luxury.
Natural-diamond prices have slid by roughly 30 percent since 2022, according to an assessment by the credit insurer. Last year’s contraction ran so deep that the government pared its 2025 growth forecast to nearly zero. Adesina’s disdain for small, scattered ventures is therefore more than bravado. It is a frank admission that Botswana cannot buy its way out of dependence with yet another assortment of workshops, pilot programs and subsidized enterprises that generate motion without generating scale.
The fund itself is a child of Botswana’s renegotiated bond with De Beers, the company whose alliance with the state has shaped the modern nation. In February 2025 the two sides signed a fresh 10-year accord governing sales of rough diamonds mined by Debswana, their jointly held venture, while extending their mining arrangements, according to Slaughter and May and De Beers. Under the deal, De Beers pledged up to P10 billion to the development fund over a decade, opening with one billion pula – roughly $75 million – according to an International Monetary Fund report. In a country of about 2.4 million people, the sum is large enough to matter and small enough to punish carelessness. Its true potency will rest less on that opening tranche than on whether it can lure pension funds, development banks, private investors and international partners to commit alongside it.
That is why Adesina casts the fund not as another dispenser of grants but as a catalytic investment platform. In development finance, “catalytic” is often a conveniently pliable word. Here it carries a precise aspiration: the fund would shoulder carefully chosen risks, groom projects for investment, and use its own capital as bait for far larger sums. Its mandate, he has said, is to crowd in financing for diversification, productivity, competitiveness and export expansion – a formulation he repeated after meeting President Duma Boko. His appointment, announced in May, hands the institution a chairman fluent in exactly this kind of financial engineering. At the African Development Bank, Adesina made his name championing platforms designed to drag projects out of policy binders and into financing rooms, where governments, lenders and investors could hammer out real transactions. De Beers framed his selection as installing an internationally recognized development economist at the helm. His assignment is to make “catalytic” denote leverage rather than mere hope.
The model he has sketched rests on a phrase now ubiquitous in African policy circles yet stubbornly hard to execute: government-enabled, private-sector-led growth. The distinction is not cosmetic. The state would name national priorities, sharpen infrastructure and regulation, and deploy public or quasi-public capital where markets stumble. Private firms would then build, compete, export and hire. Government would not withdraw, but neither would it try to become the chief operator of every factory, farm or start-up drawing on its support. Botswana’s planning documents already lean this way, framing a five-year agenda around a more diversified, inclusive economy that yields durable employment, while budget priorities trumpet private-led, export-driven growth. The African Development Bank’s country program echoes the same refrain. Such tidy alignment across paperwork can sound formidable. The thornier question is whether agencies can coordinate approvals, land, energy, logistics, skills and finance swiftly enough for a private enterprise to survive its infancy.
The stress on exports reflects a hard truth: Botswana’s home market is simply too slight to power transformation alone. Businesses serving only local buyers can furnish livelihoods, but they will rarely generate the foreign exchange, productivity and industrial depth needed to counter a protracted diamond slump. The fund is thus expected to back enterprises capable of reaching regional and global customers – through processed foods, tourism, digital services, financial products, light manufacturing or mineral value chains. Yet export promotion demands more than money. A firm must meet standards, thread customs, secure reliable transport, obtain working capital and compete on price and quality. Botswana’s landlocked geography inflates freight costs; scarce specialized skills throttle expansion. A serious platform must treat these as facets of one commercial puzzle. Financing a plant without solving its energy or transport would merely conjure a costlier stranded asset.
Adesina has said the fund will hew to “investible national priorities,” a phrase that lodges productive tension between political desire and commercial discipline. A national priority is not automatically an investible proposition. Governments may crave industries for sound social or strategic reasons, but investors still require credible demand, capable management, honest costs and a plausible route to repayment or profit. The fund’s task is to locate the narrow band where public purpose and business viability overlap – then widen it. That may mean early-stage capital, absorbing part of a project’s risk, or marrying money to technical assistance. It may also mean rejecting proposals that are politically seductive but economically frail. His pledge to concentrate on strategic intervention areas signals a selective posture: fewer projects, weightier consequences. Concentration can yield visible triumphs, but it raises the stakes of every choice. A poorly picked flagship can devour capital, corrode confidence and reduce diversification to another slogan.
One proposed instrument, the repayable grant, distills both the creativity and the ambiguity of the venture. Unlike a conventional grant, it would be returned should the enterprise flourish or hit agreed milestones, letting the money be recycled. Unlike an ordinary loan, it could offer gentler terms to firms unable to secure commercial credit early. Properly engineered, such grants can span the perilous gap between an entrepreneur’s idea and a lender’s willingness to bet on it. Poorly engineered, they breed confusion over obligations, reward insiders or become grants in all but name. The decisive matter lies in the contracts: what triggers repayment, how failure is handled, who carries currency and market risk, and whether recipients are chosen by competition or by favor.
Transparency, Adesina argues, must therefore sit at the core. That vow will be judged not by the elegance of a governance chart but by the information the fund actually discloses – selection standards, recipients, terms, conflicts of interest, performance and losses, all subject to independent audit. The fund says it has built a strong governance structure. That is a necessary opening, especially for an institution wedged between government, a global miner and private capital. It is not yet proof of independence. Development funds are peculiarly exposed to pressure, their broad missions lending easy cover to almost any outlay dressed in the language of national interest.
He has proposed measuring the fund by diversification, employment and returns. Each is sensible; none is simple. A project can add jobs while hemorrhaging money, or turn a profit while importing nearly everything and enriching little at home. Jobs may prove the most politically urgent yardstick. The International Labour Organization put total unemployment at 28 percent in 2024, with youth joblessness far higher; figures that convert diversification from an abstraction about gross domestic product into a daily reckoning with social mobility.
Botswana once epitomized natural wealth managed with restraint, its diamond rents poured into services and infrastructure rather than squandered on graft or conflict. Yet prudence never dissolved concentration risk. The realistic goal now is to make diamond income a bridge; spending today’s fading rents on businesses that can outlast tomorrow’s thinner market. That is the logic sewn into the fund’s very name.
President Boko calls it a bold initiative to ensure Batswana benefit directly from diamond wealth. The appeal is plain; the timeline is not. Diversification takes years, graduates need work now, and investors wait for proof that contracts hold. The unfinished clause hanging over the enterprise, the things Adesina says it will not do, may matter as much as its announcements. Successful development finance is built on refusal, and on the humility to admit that some careful bets will still fail. The fund begins with money, a marquee chairman and an emergency sharp enough to focus minds. What it lacks is a record – one that will be written not in speeches, but in factories that keep humming and paychecks that survive the last sale of stones.
