Closing Africa’s infrastructure gap requires between $130 billion and $180 billion a year, according to the African Development Bank, against an annual shortfall the bank puts at $68 billion to $108 billion even after accounting for what governments, development partners, and the private sector already spend. That shortfall isn’t spread evenly. Water and sanitation account for roughly 41% of it, electricity supply and transport access for about 28% each, and ICT for the remainder.
The more revealing question is why decades of development finance, dozens of continental frameworks, and a steady stream of summit pledges haven’t closed a gap of that size.
67% of GDP, Higher Than in 2000
Part of the answer sits on the liability side of the ledger. Africa’s public debt reached 67% of GDP in 2024, higher than the 62% recorded in 2000, the year before the continent’s major debt-relief initiatives began working through the system. Eight African countries are currently in debt distress, and 15 more face a high risk of joining them. Over 2019 to 2023, African governments spent, on average, seven times more servicing debt than building infrastructure. In 15 countries, interest payments now exceed infrastructure spending outright.
That’s the mechanism behind the widening: money that would otherwise fund roads, grids, and water systems is instead flowing toward creditors, at a moment when the debt-to-GDP ratio is already worse than it was before the last relief effort.
Aid Fell by $1.8 Billion in One Year
Development finance was supposed to be the offset. It’s moving in the opposite direction. Disbursements for African infrastructure fell from $16.6 billion in 2022 to $14.8 billion in 2023, and preliminary 2024 figures point to a further real-terms decline, with projections of a cumulative 16% to 28% drop in OECD development aid to Africa between 2023 and 2025. China, once the continent’s largest single infrastructure funder, cut its commitments from $25.7 billion in 2018 to $6.7 billion in 2019 and $6.5 billion in 2020, a retreat that followed criticism, including from China’s own government, over its lending’s role in Africa’s debt burden.
Private capital hasn’t filled the space either. Global private infrastructure investment tripled between 2013 and 2022. Africa’s share of it stayed at 6% to 8% throughout.
90% of Projects Never Reach Financial Close
The gap has a second driver that has nothing to do with the amount of money in circulation: most of the projects designed to spend it don’t survive long enough to spend anything. Early-stage preparation, feasibility studies, technical design, environmental review, financial structuring, can consume 5% to 12% of a project’s total cost and take up to seven years to complete. Up to 90% of infrastructure projects in Africa fail before reaching financial close, and roughly 80% of those stall at the feasibility stage specifically, before a shovel goes in the ground or a contract gets signed.
The continent’s own flagship infrastructure programme illustrates the pattern at scale. Under its first phase, running from 2012 to 2020, 51 cross-border programmes and 409 individual projects produced real, physical output, more than 16,000 kilometers of roads, 4,000 kilometers of railways, 3,500 kilometers of transmission lines. Yet only 18% of the targeted projects were actually operational by 2025. The constraint sat in preparation and financial structuring, the stage between an approved plan and a project actually under construction, not in the scale of the ambition itself.
Debt, Retreat, and a Broken Pipeline
Three separate mechanisms, running at the same time, explain why the gap widens instead of closing. Rising debt service is consuming the fiscal space governments would otherwise spend on infrastructure. The external financing that was supposed to offset that constraint, development aid and Chinese lending alike, is contracting rather than expanding. And even where capital exists and a government has room to deploy it, roughly 9 in 10 projects never make it through preparation to a signed, funded contract.
Each of those problems has its own fix, and none of them is a larger headline pledge. A continental financial architecture with its own dedicated financing arm was one of the tools designed specifically to absorb that kind of structural gap: raising capital independent of any single government’s balance sheet, financing preparation costs upfront, and channeling resources toward exactly the sectors where the shortfall concentrates. That is close to the description of a gap a dedicated, capitalized continental investment bank was designed to help close, an institution that exists on paper and has yet to exist in practice.
Until the debt trajectory, the financing retreat, or the project-preparation failure rate changes, on their own or together, the $68 billion to $108 billion annual shortfall has no structural reason to narrow. On current trends, it has every reason to keep doing what it has done for the past decade: widen.
