AfDB accelerates private capital mobilisation to bridge Africa’s $402 billion funding gap

The African Development Bank Group has escalated efforts to mobilise private capital as a central strategy to close what it describes as Africa’s widening development financing gap and to accelerate a sustainable economic transition across the continent.

According to the AfDB, Africa faces an annual development financing shortfall estimated at roughly $402 billion, a figure the bank highlighted during the inaugural Africa Private Capital Mobilisation Day in London on 17 December 2025. The event, convened in partnership with the UK government and attended by more than 150 senior investors, marked an explicit shift from dialogue to execution, signalling a push to channel equity, debt and institutional investment into African projects.

The bank says public budgets and traditional development assistance are no longer sufficient, particularly as many governments confront rising debt servicing costs, climate shocks and global economic uncertainty. To attract private investors to projects often seen as too risky, the AfDB is emphasising de‑risking tools: guarantees, blended finance structures, technical advisory support and co‑investment. In his opening remarks at the London meeting, AfDB President Dr Sidi Ould Tah urged a large‑scale, coordinated mobilisation that pairs concessional resources and guarantees with private capital to scale investment across infrastructure, energy, agriculture, healthcare and climate adaptation.

Blended finance features prominently in the bank’s playbook. By combining concessional funding with private-sector investment, the AfDB says it can improve project bankability, lower perceived risks and generate returns that make projects more attractive to pension funds, institutional investors and commercial financiers. The bank’s recent $20 million equity commitment to the Africa50 Infrastructure Acceleration Fund I, which aims to mobilise up to $500 million for power, digital, transport and water projects, was presented as an example of using limited public resources to catalyse much larger pools of private capital.

Energy and climate finance are priority sectors. The AfDB argues that closing Africa’s persistent energy deficit, by backing renewable generation, transmission upgrades and off‑grid solutions, is essential for growth and job creation, while mobilising private capital for climate adaptation and mitigation is vital because African countries bear outsized climate risk despite contributing little to global emissions.

The bank is also pushing institutional reforms to unlock domestic savings. According to AfDB communications around the London event and related meetings in Abidjan, the institution is promoting a New African Financial Architecture and a Pan‑African Financial Coordination Platform to deepen capital markets, strengthen regional cooperation among development finance institutions, and channel sovereign wealth, pension assets and other long‑term domestic funds back into productive continental investment. Panels at the 2025 Africa Investment Forum echoed that message, warning that time is running out to close infrastructure and climate finance gaps unless governments mobilise domestic capital now.

Public‑private partnerships remain a core mechanism. The AfDB says it is helping governments design bankable PPP frameworks to unlock private expertise and balance sheets for large projects, roads, ports, power plants and digital networks, while also bolstering project preparation capacity so schemes reach financial close. At the same time, the bank acknowledges persistent barriers: perceived political risk, currency volatility and weak project pipelines continue to deter some investors, underscoring the need for coordinated policy reform, stronger legal frameworks and improved transparency to build investor confidence.

The AfDB frames its role as a catalyst rather than sole financier. By co‑investing with sovereign funds, development finance institutions and private investors, and by deploying guarantees and blended instruments, the bank aims to multiply the developmental impact of constrained public resources. Stakeholders welcomed the pivot to private capital, noting that with the right mix of risk mitigation, institutional support and policy reforms, private investment can be transformative for industrialisation, agriculture value chains, food security and the continent’s energy transition.

The bank cautioned that mobilisation must deliver inclusive and sustainable outcomes. Projects supported through private finance, it said, should meet environmental, social and governance standards to ensure long‑term benefits for communities and to guard against short‑term profit motives overriding development aims.

As global investors increasingly seek new growth arenas, the AfDB is positioning itself as a trusted partner and risk mitigator to channel international and domestic private capital into Africa. But closing the continent’s financing gap, the bank concludes, will require sustained collaboration among governments, regulators, development partners and private capital providers to turn commitments into financed projects and measurable development outcomes.
