- Africa Can Unlock $1.43 tn Annually Through Smarter Public Investment – AfDB
The African Development Bank has projected that African economies could unlock up to $1.43 trillion annually through stronger domestic revenue mobilisation, improved public spending efficiency and deeper private-sector participation, as governments across the continent confront widening fiscal pressures and a growing development financing gap.
The estimates were contained in the Bank’s 2026 African Economic Outlook report, launched during the AfDB Annual Meetings in Brazzaville under the theme “Mobilizing Africa’s Development Financing at Scale in a Fragmented World.”
According to the report, African countries are currently forfeiting about $299 billion every year through weak public investment efficiency, highlighting the scale of fiscal leakages limiting infrastructure delivery, industrialisation and long-term economic transformation.
The AfDB further estimated that governments across the continent could generate an additional $469 billion annually through stronger tax administration reforms and enhanced non-tax revenue mobilisation.
The findings come at a time when African governments are under pressure to finance infrastructure, climate adaptation, food security, jobs and industrial development, while facing high borrowing costs, weak domestic savings and reduced access to concessional financing.
In one of the report’s central conclusions, the AfDB said every additional dollar of efficient public investment could attract about $1.40 in private capital through stronger public-private partnership frameworks.
That finding underscores the catalytic role of government spending when public investment is well planned, transparently executed and linked to commercially viable projects.
For the Bank, Africa’s financing challenge is not only a question of limited resources. It is also a question of how effectively existing public resources are mobilised, allocated and used to attract private capital.
Despite growing global institutional liquidity, Africa continues to attract only a small share of long-duration investment. The report noted that institutional investors, including pension funds, insurers and sovereign wealth funds, currently manage close to $4 trillion in assets globally, yet less than 2.7 per cent is allocated to infrastructure and productive sectors across Africa.
The AfDB described this weak allocation as a major structural constraint on the continent’s industrialisation and infrastructure ambitions.
The report also warned that Africa’s annual financing shortfall to achieve the United Nations Sustainable Development Goals now exceeds $1.3 trillion, with pressures compounded by rising debt vulnerabilities, illicit financial flows, weak domestic savings mobilisation and tighter global financial conditions.
The challenge is particularly urgent because many African countries are still recovering from the fiscal shocks of the pandemic, global inflation, currency depreciation, climate stress and elevated debt service costs.
For governments, the AfDB’s message is clear: the continent cannot finance its transformation through external borrowing alone. It must raise more revenue at home, spend more efficiently and use public investment to crowd in private capital.
The report nevertheless maintained that Africa remains one of the world’s fastest-growing regions, despite heightened geopolitical tensions, supply chain disruptions and elevated borrowing costs globally.
Regional projections showed East Africa retaining its position as the continent’s fastest-growing sub-region, although growth is expected to slow to 5.9 per cent in 2026 from 6.6 per cent in 2025 amid rising energy and import costs linked to Middle East tensions.
West Africa is projected to grow by 4.7 per cent in 2026, supported by agricultural expansion and infrastructure investment, while Central Africa is forecast to expand modestly to 3.8 per cent, largely driven by elevated oil prices.
Southern Africa is expected to remain the continent’s slowest-growing region, with projected growth of 2.1 per cent, reflecting weaker mining activity, slowing agricultural productivity and rising energy costs.
The regional picture reinforces a broader point: Africa’s growth story remains resilient, but uneven. Countries with stronger fiscal institutions, better investment execution and deeper domestic capital markets are likely to be better placed to withstand external shocks and finance development priorities.
For Ghana and other West African economies, the AfDB’s findings carry direct relevance. The pressure to mobilise domestic revenue, improve public investment efficiency and attract patient capital has become more urgent as countries seek to reduce dependence on expensive external borrowing.
The Bank’s report strengthens growing calls for African governments to deepen fiscal reforms, modernise tax systems, improve procurement, reduce waste and strengthen institutional accountability.
It also places renewed emphasis on capital market development. Pension funds, insurance assets and sovereign wealth funds could become important sources of long-term financing if regulatory frameworks, risk-sharing instruments and project preparation systems are strengthened.
The AfDB’s projection of $1.43 trillion in potential annual resource mobilisation is therefore both an opportunity and a warning.
The opportunity is that Africa has more financing capacity than it currently uses. The warning is that without fiscal discipline, institutional reform and credible project pipelines, the continent will continue to depend on costly and uncertain external financing.
Africa’s development challenge is no longer only about finding money. It is about building systems that make public money work harder, attract private capital and convert growth into structural transformation.
