The scale of Africa's infrastructure financing gap exceeds public sector capacity. Africa's annual infrastructure financing gap stands at $170 billion, according to the African Development Bank (2023). Public expenditure on infrastructure across the continent averages below 3% of GDP, less than half the 5 to 7% threshold required to support economic growth. The consequence is visible across every productive sector: over 600 million Africans lack reliable electricity, and logistics costs across the continent run two to three times the global average, directly constraining trade and investment.
Nigeria's position within this continental picture is acute. Nigeria requires an estimated $3 trillion over 30 years to close its infrastructure deficit, a figure that renders any “public-finance-only” strategy structurally insufficient.
Nigeria's sectoral deficits span every productive vertical.

Africa’s private capital market base is enough to close the gap but is not being deployed in infrastructure.
Global infrastructure assets under management exceeded $2.2 trillion in 2025, up from $1.5 trillion in 2023 (Preqin). Africa-focused private equity and infrastructure funds collectively manage more than $2.5 trillion in committed capital. Nigerian pension funds alone hold N19.4 trillion ($14.3 billion) in AUM. Clearly, the capital base exists but the problem is that it is not being deployed at scale to fund infrastructure at both regional and national levels.
For instance, Africa receives less than 2% of global infrastructure investment despite housing 19% of the world's population. Pension fund infrastructure allocations remain below 1% of the portfolio. This confirms that the real constraint is not capital scarcity, but the absence of conditions that make deployment viable at scale.
Four structural barriers prevent private capital deployment in infrastructure at scale
1. Less than 15% of Nigerian infrastructure projects meet minimum investor-readiness criteria.
Most proposed infrastructure project ideas reach investors without viable feasibility assessments, structured revenue models, or creditworthy offtakers. Less than 15% of Nigerian infrastructure project proposals meet minimum investor-readiness criteria. To make infrastructure more attractive for private capital, Nigeria must improve the investor-readiness of its project development pipeline. This will require project sponsors to mandate high-standard feasibility assessments, establish creditworthy offtaker frameworks, and structure risk allocation before projects even reach private investors.
2. We must rethink infrastructure risk sharing in a way that reduces private capital exposure.
Nigeria ranks among the top 10 most volatile markets globally from a currency perspective. Historically, infrastructure revenues are denominated in naira but with dollarised obligations. This has continued to create an exchange risk that makes it difficult for private capital to participate. For instance, the naira depreciated by over 40% in 2023 alone, leading to losses that most unhedged transactions cannot absorb. Without credible FX risk management mechanisms, this barrier will persist. Concessional capital deployed through institutions such as InfraCredit and MIGA demonstrably de-risks infrastructure transactions. Nigeria must scale these instruments systematically, rather than deploying them on an ad hoc, deal-by-deal basis.
3. Governance and investor protection is critical for private sector confidence.
Nigeria ranks 131st of 190 countries on the World Bank's contract enforcement index. Inconsistent sector regulation, weak PPP contract enforcement, and opaque approval processes extend pre-construction timelines and directly compress investor returns, increasing perceived risk beyond what underlying fundamentals justify. Attracting private capital (whether local or foreign) at scale requires enforceable, rule-bound PPP contracts, standardised processes, and independent sector regulators insulated from political pressures. A transparent foreign exchange framework and governance is a key requirement for serious private institutional participation.
4. The market infrastructure for blended finance must be built to scale, not deployed on an ad hoc basis. About us:
