YEMI OSINBAJO, SAN, GCON, IMMEDIATE PAST VICE PRESIDENT OF THE FEDERAL REPUBLIC OF NIGERIA, AT THE 3RD AFRICA WORLD INITIATIVE (AWI) LECTURE TITLED: RESOLVING AFRICA’S TRIPLE CONUNDRUM IN PRINCETON UNIVERSITY, NEW JERSEY, U.S., ON THE 13TH OF NOVEMBER, 2025

PROTOCOLS

It is such a great pleasure to be here, and I am deeply honoured to have been invited by Prof Chika Okeke-Agulu and his team at the Africa World Initiative (AWI) to give this lecture. Thank you very much for the invitation. And I must commend AWI for the exciting work you are doing in so many diverse fields, from the Africa Archives Project to the Tech and Innovation Partnerships, African Languages and AI. Well done indeed.

I will be speaking for a few minutes on the topic of Resolving Africa’s Triple Conundrum. Africa today stands at a historic crossroads. With a population nearing 1.4 billion people, a median age of about 19 and one of the fastest-growing workforces in the world, 30% of the world’s mineral reserves, including critical minerals and rare earths, and 60% of the world’s arable land, the continent holds extraordinary potential. Yet that promise is constrained by a “triple conundrum”: a mounting public-debt burden and an excessively high cost of capital; acute climate vulnerability that is already eroding lives, assets, and livelihoods; and persistent structural development constraints that limit productivity, job creation, and opportunity. These three challenges are not isolated; they are tightly interwoven and mutually reinforcing. Together, they create feedback loops that can turn what should have been temporary shocks into prolonged stagnation.

I will, in a few minutes, outline each dimension of the conundrum, show how they interact, and propose responses that can help Africa escape this trap and realise its full potential.

Let me begin with debt, because it is often the sharpest pressure point and because it directly constrains everything else. By 2023, Africa’s public and publicly guaranteed external debt had reached about US$1.15 trillion, representing roughly 60% of total public debt. The average debt-to-GDP ratio was projected to decline modestly from 68.9% in 2023 to 64.3% in 2025, but this is still high given limited revenue bases and large development needs. More than 60% of African countries have debt-to-GDP ratios exceeding 50%.

Some face particularly acute pressures: Mozambique (98.1% debt-to-GDP), Cabo Verde (90.1%), and Egypt (88.3%) are clear examples. However, the deepest concern is not simply the size of the debt stock, but its composition and cost. A rising share is denominated in foreign currencies or carries short maturities. This exposes countries to exchange-rate risk and to sudden shifts in global financing conditions.

When global interest rates rise or investor sentiment swings, refinancing can become dramatically more expensive, and that is if it is available at all. Also, African sovereign bond yields and spreads remain well above those of comparable emerging markets, and in several cases, they exceed expected growth rates. Nigeria’s 10-year sovereign yield has been about 15.6%, against a projected 2025 growth rate of 3.9%. Kenya faces yields around 13.1% with expected 2025 growth at 4.5%. Egypt’s 10-year yields are roughly 20.1%, while its projected 2025 growth is about 4.3%. When borrowing costs are several times higher than economic growth, debt dynamics become extremely difficult to sustain.

Overall, borrowing costs have risen to about 8.2% in 2024. As a result, debt service now absorbs large and rising shares of government revenue. In many countries, debt servicing consumes double-digit proportions of fiscal resources, crowding out critical spending on education, infrastructure, climate resilience and health. Twenty African countries reportedly spent more on debt service than on health in 2022. This is not an abstract statistic; it represents classrooms, clinics, and climate-proof infrastructure that are not built because interest payments take precedence. Short-term debts and a narrow circle of lenders leave many African nations walking a financial tightrope.

When global liquidity tightens, countries with large near-term maturities face surging borrowing costs — or find access to markets abruptly cut off. Governments are then forced into an impossible choice: channel scarce resources toward costly debt repayment at the expense of essential investment and services, or maintain spending on development priorities and risk falling into distress. The challenge is even greater when debt is concentrated among a small group of creditors. A limited lender base reduces options and increases exposure to external shocks. We saw this in Zambia, where reliance on a few major creditors complicated the debt resolution process following its 2020 default. Ghana’s experience was similar — heavy exposure to international bond markets left it vulnerable when global interest rates rose, leading to loss of market access and eventual restructuring.

These examples underscore a broader lesson: financial concentration is a systemic vulnerability, not a local misstep. It highlights the shared responsibility of borrowers and lenders alike to build a more resilient, transparent, and inclusive financial architecture — one that enables countries to invest in their people without the constant shadow of crisis.

For many fiscally stretched African economies, a single severe shock can tip the balance from “manageable” to “unsustainable”. Mozambique offers a stark example. In 2019, Cyclone Idai caused estimated losses of over US$2 billion — around 13% of GDP. Growth fell from about 6% to below 2%, while reconstruction costs and lost export revenues pushed public debt above 100% of GDP, culminating in sovereign default. Zambia, also hit by drought and falling copper prices, saw revenue and foreign-exchange earnings eroded and became Africa’s first pandemic-era sovereign defaulter in 2020. At the same time, creditor composition has shifted significantly. Commercial and other private creditors now hold a large share of external debt, while multilateral creditors hold much of the external debt of IDA-eligible low-income countries. This makes debt resolution more complex. Mechanisms that were designed when official bilateral creditors were in the majority are no longer sufficient unless they include private creditors and address the treatment of multilateral claims.

The second dimension of the triple conundrum is the climate crisis, which is a powerful stress multiplier for African economies and public finances. Africa contributes relatively little to global greenhouse gas emissions, yet it is the fastest-warming continent. Temperatures and precipitation patterns are changing. Droughts, floods, storms, and heatwaves are becoming more frequent and more intense. Hundreds of millions of Africans live in areas highly exposed to climate hazards: low-lying coasts threatened by sea-level rise and erosion; arid and semi-arid regions where droughts are intensifying; and informal urban settlements built on flood-prone and poorly drained land. Agriculture, which remains the main source of income and employment in many African countries, is especially vulnerable.

Recurrent droughts and unpredictable rainfall patterns reduce crop yields and heighten food insecurity. To cope, households often sell productive assets or incur high-cost debt, weakening long-term resilience and shrinking the taxable base. Urban economies and infrastructure are similarly exposed. Floods and storms damage roads, bridges, power systems, ports, hospitals and schools. Each disaster generates direct repair costs and indirect losses from disrupted trade and service delivery. It is estimated that natural disasters cause around 12.7 billion US dollars in infrastructure and building losses annually across Africa, with nearly 70% of these losses due to floods. In some low-income countries, climate-related shocks can wipe out up to 6% of GDP in a single year —a crippling setback for economies already burdened by debt. Between 2021 and 2022, more than 52 million Africans were affected by droughts and floods.

Those numbers represent real people — farmers, traders, small-business owners — whose livelihoods have been disrupted or destroyed. Looking ahead, Africa faces potential economic losses of $289 – 440 billion by 2030 if adaptation and resilience measures are not dramatically scaled up. Climate shocks transmit directly into fiscal stress. They reduce revenues as economic activity slows and trade is disturbed. At the same time, they compel governments to increase emergency spending and reconstruction outlays. These pressures often emerge precisely when global financial conditions are tightening, leaving governments with few options beyond short-term, high-cost borrowing or deep cuts in planned development spending. Over time, recurrent climate shocks trap countries in a cycle of asset loss, interrupted schooling, rising food insecurity and chronic fragility. So the climate crisis is not only an environmental challenge; it is a central fiscal and development challenge.

The third component of Africa’s triple conundrum is a set of structural constraints that hold back productivity and growth, and thus weaken resilience. Infrastructure deficits remain severe. In many countries, electricity is unreliable and expensive; ports are congested; roads and railways are inadequate; and digital connectivity is limited. High energy costs and frequent power outages undermine competitiveness and discourage investment, making it difficult to develop labour-absorbing manufacturing and modern service sectors. Logistics inefficiencies and non-tariff barriers compound these problems. Slow customs procedures, fragmented regulations and weak corridor management significantly increase the time and cost of moving goods.

Human-capital gaps and skills mismatches are another critical constraint. Education systems often do not produce enough graduates with technical, vocational and managerial skills suited to modern industry and services. The result is a painful paradox: high youth unemployment and underemployment, alongside firms reporting shortages of qualified technicians, engineers and managers. Access to finance is also limited and costly. Small and medium-sized enterprises — the backbone of job creation — struggle to obtain credit at reasonable rates. Long-gestation infrastructure projects face similar difficulties. Shallow domestic capital markets push governments and firms toward foreign-currency borrowing, with all the associated exchange-rate risk. Weaknesses in public financial management and incomplete data systems further elevate perceived sovereign risk, raising the cost of borrowing.

These structural issues reduce the productivity and returns on investment. When the returns to public and private investment are low or uncertain, it becomes harder to grow out of debt and to build the buffers needed to absorb shocks. Debt, climate vulnerability and structural weaknesses are tightly linked. High debt-service burdens reduce fiscal space for precisely the investments that could lessen climate and development risks — such as early-warning systems, climate-resilient infrastructure, social protection and insurance mechanisms. When a climate or commodity shock hits, governments face simultaneous revenue shortfalls and spending pressures, just as access to affordable finance tightens. This leads to costly emergency borrowing or sharp cuts in investment, both of which undermine long-term growth.

Underdeveloped infrastructure and limited institutional capacity amplify losses from shocks. When drains, roads, power lines and health systems are weak, disasters are more damaging and recovery is slower. This depresses the productivity of investment and increases perceived risk, feeding into higher borrowing costs. The global financial architecture often amplifies these vulnerabilities. African sovereigns pay higher spreads than peers with similar fundamentals, and they have less access to countercyclical, low-cost financing. Rating-agency practices, limited African representation in global financial governance, and constrained concessional windows all contribute to structural disadvantage.

The result is a powerful feedback loop in which temporary shocks — climate events, commodity swings, or global financial turbulence — too easily become long-term setbacks. Breaking this vicious cycle requires an integrated strategy. In my view, there are at least six pillars that must move together to resolve Africa’s triple conundrum.

The first pillar is to address the debt problem decisively, both at the country level and in the global system. The global debate on debt reform is gaining momentum. The IMF and World Bank have expressed support for stronger restructuring mechanisms, the United States has signalled possible backing, and South Africa, as current G20 president, has placed debt high on the agenda. Several of the major debt relief initiatives are converging around some core demands, these include:

1. Stop net financial outflows from distressed countries, including via heavy IMF repayments.

2. Mobilize new IMF resources through limited gold sales and reallocation of unused SDRs from rich countries to vulnerable ones. The IMF’s large gold holdings could, with a small sale, raise billions for concessional lending or debt relief.

3. Link debt relief and rescheduling to climate and nature-resilient growth plans, so that investment in resilience is rewarded.

4. Revise IMF/World Bank Debt Sustainability Frameworks to reflect development realities and climate risks, not just narrow liquidity indicators.

5. Introduce contingency clauses into new loans — allowing automatic pauses in debt service during natural disasters, pandemics or major commodity shocks.

6. Expand debt-for-development and debt-for-nature swaps and create new sustainable-finance instruments.

7. Provide advisory and capacity-building support to help countries manage borrowing prudently and invest in high-return projects.

8. Establish a “South Club” of borrower countries — or strengthen the Sustainable Debt Coalition — to coordinate strategies and increase bargaining power.

9. Create a regular global forum, such as an annual Financing for Development meeting, to institutionalize dialogue on debt, climate and development.

These are the common asks of the most prominent debt relief initiatives. At the same time, Domestic Resource Mobilization (DRM) must be part of the compact. As aid budgets stagnate, low and middle-income countries must raise more revenue from domestic taxation and savings. For some creditors, improved DRM may become a condition for more generous debt relief, especially in the Paris Club.

Let me speak briefly on a debt relief effort that I am a part of: the African Leaders Debt Relief Initiative (ALDRI), headed by President Olusegun Obasanjo, with six other former Heads of State.

ALDRI’s plan is a bold, Africa-focused plan, drawing on the Brady Plan (1989) and the HIPC Initiative (1996–2005), both of which successfully reduced debt and restored growth, ALDRI responds to today’s context, including the inadequacy of the G20 Common Framework, under which Zambia, for example, waited nearly two years for debt restructuring. ALDRI’s four key actions are:

1. Comprehensive debt relief — cutting or cancelling unsustainable debts, including for highly climate-vulnerable countries.

2. Inclusive and transparent restructuring — ensuring that all creditors, including private lenders and China, share responsibility equitably.

3. Lower borrowing costs — through expanded concessional financing, reduced risk premia, and provisions that allow repayment pauses during crises.

4. Reformed debt architecture – stronger African representation in global financial institutions and movement toward a UN-based sovereign debt resolution framework. ALDRI warns that without such reforms, many developing nations face another “lost decade” of austerity and stagnation, and insists that debt relief is development justice.

The second pillar is to reduce the cost of capital for African countries and to reform global finance so that Africa is not systematically penalised. In the near term, this requires re-channelling concessional resources and reallocating SDRs to create African windows for low-cost, long-tenor finance, especially for climate adaptation and resilient infrastructure. It also means scaling up de-risking instruments — partial-risk guarantees, blended-finance platforms, first-loss facilities, and political-risk insurance— to crowd in private investment at lower cost. In the medium term, we must reform how risk is assessed and communicated. Supporting regional rating agencies and demanding more transparent and context-sensitive methodologies that ensure that ratings reflect not just market moods, but also structural improvements and climate investments.

In the long term, governance reforms in global financial institutions are needed so that Africa’s structural needs are taken seriously in rule-setting. This is a political project that must proceed alongside technical changes. A crucial element of this pillar is Natural Capital Accounting (NCA). Africa’s forests, peatlands, rivers, biodiversity and minerals are often invisible in traditional national accounts. Countries appear “poor” despite vast natural wealth, and this affects their creditworthiness. Natural Capital Accounting aims to measure and value natural assets systematically.

Forests are recognised as carbon sinks; mangroves as natural storm barriers; peatlands as climate regulators. When these assets are properly accounted for, they become bankable for green bonds, conservation bonds and debt-for-nature swaps. Some African countries are already taking the lead. Botswana uses water and mineral accounts to guide pricing and extraction. South Africa incorporates biodiversity accounts into development planning and has attracted private conservation finance. Liberia and Uganda are piloting wetland and forest valuation with support from WAVES (Wealth Accounting and the Valuation of Ecosystem Services) and UN partners. This work is not a luxury; it is essential for turning natural wealth into sustainable financial strength.

The third pillar addresses the resolution of two intertwined threats: the climate emergency and Africa’s extreme energy poverty, by proposing a grand bargain between Africa and the global community. Africa is the fastest-warming continent and also home to some of the world’s highest energy-poverty rates. Over 600 million Africans lack electricity, and nearly 1 billion lack clean cooking. Energy poverty holds back industrialisation, productivity and human development. But the crucial point is this – if Africa industrialises using the same carbon-intensive model as many advanced economies, its emissions could reach 9.4 gigatons of CO₂-equivalent annually, making it responsible for up to 75% of global GHG emissions by 2050.

In that scenario, the world would not achieve net-zero. Africa could become the problem — or it could become the solution. Africa can be the solution if it pursues Climate Positive Growth — reaching middle to high-income status while keeping emissions flat or even lowering them, by taking advantage of its climate competitiveness. The continent has some of the world’s best untapped renewable resources, a young and entrepreneurial labour force, and significant natural assets. Because its industrial base is still relatively small, Africa can build a new greenfield industrial system powered by clean energy, avoiding the massive costs of retiring legacy fossil-fuel assets. With around 60% of global renewable-energy potential, Africa can become a major climate-action powerhouse — greening global manufacturing and supply chains, protecting carbon sinks, and helping remove carbon from the atmosphere.

To keep its own side of the grand bargain, namely maintaining a carbon negative growth paradigm for its development, African countries must ensure that Climate Positive Growth is a feature of their economic planning and that relevant legislation is enacted. The global community, on the other hand, must provide appropriate and sufficient finance and investments, fair and equitable market access for the green industrial goods that would be produced, and also for African carbon credits, which today are very poorly priced.

Reversing energy poverty is another component of resolving the twin existential crisis. Africa’s renewable potential is estimated at 50 times the projected world electricity demand by 2040. Yet power outages and high tariffs remain common. Many initiatives focus on off-grid and mini-grid solutions, which are important but often financially fragile and too small to drive industrial transformation. A more scalable model is anchor-demand industrialisation. Large, energy-intensive industries, such as data centres, green hydrogen and ammonia plants, and mineral processing facilities — can be located near renewable resources and commit to long-term power-purchase agreements. Their demand makes large renewable projects bankable; surplus power can then serve households and small businesses at lower cost. This aligns with global trends: as industries seek low-carbon production locations, Africa’s combination of renewables, strategic geography and raw materials becomes attractive.

Three industry types stand out: 1. Energy-hungry and energy-cost-driven industries, such as green data centres and Direct Air Capture plants. Microsoft’s planned 1 GW geothermal-powered data centre in Kenya’s geothermal-rich Olkaria region in the Rift Valley is an illustrative example.

2. Strategically located industries, including the production of green fuels — hydrogen, ammonia, methanol — for shipping and aviation, and green fertilisers to support food security.

3. Resource-based industries, where Africa refines its own resources — cobalt, bauxite, lithium, iron, copper — into green metals, capturing greater value and jobs. For example, processing Africa-mined bauxite, which is 25% of global production, with renewable energy near bauxite mines in Africa will save 1% of global emissions and generate over 280,000 jobs and US$37 billion of additional revenue. Similarly, Africa is a prime location for green hydrogen, sustainable fuels and green fertilizer. Angola, Namibia and South Africa are advanced in their green hydrogen investment plans.

To fully realise this potential, Africa must improve regulation, skills and logistics; lower the cost of capital through de-risking, blended finance and long-term purchase agreements; and secure fair treatment in global trade rules, including under the EU Carbon Border Adjustment Mechanism, so that greener African exports are recognised and not unfairly penalised. By linking vast renewable resources to anchor industrial demand and then extending power to households and SMEs, Africa can tackle energy poverty, create jobs, add value to its resources and become a global leader in green growth.

The fourth pillar is to systematically build climate resilience and anticipatory finance mechanisms. Investments in robust early-warning systems, meteorological networks and climate services pay for themselves many times over. They enable anticipatory action: cash transfers before a drought fully hits, evacuation before a flood peaks, and pre-positioning of relief supplies. These measures reduce the human and economic toll of disasters. At the same time, expanding sovereign and sub-sovereign catastrophe insurance and strengthening regional risk pools can provide rapid post-disaster liquidity, reducing the need for expensive emergency borrowing. Premiums and coverage should be designed to incentivize risk reduction, investments in nature-based solutions, resilient infrastructure, and sound land-use planning that reduce expected losses over time.

The fifth pillar is to unlock Africa’s development potential by fully implementing the AfCFTA and investing in regional public goods. The AfCFTA is not merely a trade deal; it is a transformative development project. By creating a single African market, it aims to accelerate industrialization, job creation and global competitiveness. With a combined GDP of US$3.4 trillion, the AfCFTA is projected to boost Africa’s income by about US$450 billion by 2035, create some 14 million jobs, and lift around 50 million people out of extreme poverty. Since its signing in 2018 and operational launch in 2021, implementation has advanced: more than 45 countries have adopted tariff-concession schedules; rules of origin have been agreed for about 90% of products; and 24 services schedules have been adopted.

The 10 billion dollar AfCFTA Adjustment Facility will help countries adjust to tariff reductions, and this is important given that tariffs contribute around 10% of revenue in many states. Two critical digital platforms are operational. The Pan-African Payment and Settlement System (PAPSS) operates in 15 countries with 51 banks, enabling cross-border payments in local currencies. MANSA, a continental due diligence repository, simplifies KYC and reduces compliance costs for cross-border trade and investment. Yet major hurdles remain.

Africa’s transport and logistics network is a binding constraint. Under the Guided Trade Initiative, a test run of the operation of the AFCFTA, a shipment of Exide batteries from Kenya to Ghana took about six weeks because it had to pass through Singapore to consolidate cargo. This example illustrates how limited intra-African shipping and logistics capacity forces detours through non-African hubs, adding cost and delay. To unlock AfCFTA’s promise, Africa must invest heavily in regional infrastructure — roads, rail, ports, airports, power pools and digital backbones. These projects will often be cross-border and require blended financing that shares risks among countries, development banks and private investors.

Equally important is trade facilitation: single electronic windows, streamlined customs procedures, corridor management, and mutual recognition of standards to reduce the cost and time of trade. Ratification and implementation of the Free Movement of Persons Protocol would unlock labour mobility and support integrated labour markets. Alongside this, we must support industrial upgrading through robotics, AI and the Internet of Things, and help firms meet regional and international standards. This shift from raw-commodity exports to higher-value manufacturing and services will broaden the tax base and strengthen resilience.

The sixth pillar is the domestic reform agenda that underpins everything else. Strengthening domestic resource mobilization is critical: broadening tax bases, digitizing tax administration, and curbing illicit financial flows. When fiscal revenues rise and are managed transparently, governments can finance resilience, infrastructure and social protection in a sustainable way. Improving public investment management is equally important: rigorous project appraisal, cost-benefit analysis, climate screening, and transparent procurement help ensure that investments are of high quality, deliver strong returns, and are attractive to co-financiers.

Finally, investing in skills, standards, and technology adoption will enable African firms and workers to participate fully in emerging green and digital value chains. Education systems must produce the engineers, technicians, coders, logisticians and managers needed by a climate-positive, integrated economy.

Each of these 6 pillars is essential, but none is sufficient on its own. Addressing debt without improving productivity and resilience only buys time before the next crisis. Scaling climate finance without changing the cost of capital and debt composition leaves countries dependent on expensive and volatile funding. Implementing the AfCFTA without the infrastructure and finance for firms to scale limits its impact. The solutions must therefore be integrated so that debt reform creates fiscal space for climate resilience, infrastructure and human capital.

Lower-cost capital and de-risked projects crowd in private investment and support structural transformation. Climate resilience and anticipatory finance reduce the frequency and magnitude of fiscal shocks, stabilising debt dynamics. And AfCFTA and regional integration amplify the returns to domestic reforms by enlarging markets and broadening tax bases. Together, these elements convert reactive crisis management into a durable development strategy.

Let me close with a call to action to three groups: African governments, regional institutions and global partners, and multilateral institutions. African governments must accelerate domestic reforms: adopt transparent debt-management practices, procurement processes, curb illicit financial flows, curb official corruption, strengthen domestic resource mobilization; improve public investment appraisal and procurement, and advance trade facilitation measures. They must prioritise climate-proof, job-creating investments and collaborate regionally to pool risk and finance large cross-border projects.

Regional institutions and the African private sector should operationalise de-risking platforms, expand trade finance, scale regional catastrophe risk pools, and mobilise domestic pension and insurance savings into long-term productive investments. Investing in Africa’s green transition, connectivity, and integration is not charity; it is a compelling business opportunity.

Global partners and multilateral institutions must support SDR reallocation and new concessional windows for adaptation; they must reform creditor coordination processes; promote transparent, fair rating practices; and ensure stronger African representation in global financial governance. The rules that determine the cost of capital must no longer lock Africa into structural disadvantage. Re-engineering the global financial architecture is both political and technical. It demands leadership, coalitions and moral clarity. But we do not need to wait for a perfect system before acting. Practical tools — debt-for-resilience swaps, blended-finance platforms, risk pools, anticipatory action systems and AfCFTA trade facilitation measures — already exist. If deployed at scale and in coordination, they can deliver substantial gains in the near term.

Africa’s triple conundrum is not destiny. It is the product of interlocking constraints that can be overcome by an equally interlocking response: better managed and fairer debt, a lower and more just cost of capital, scaled climate resilience, and faster structural transformation driven by regional integration and domestic reform. If we align fiscal prudence with bold public investment, de-risk private capital while insisting on transparency, and pair regional integration with robust social protection, we will not merely manage crises, we will unlock Africa’s transformation. And that transformation will be good for Africa and good for the world.

Thank you.
