Beyond Project Risk; Capital and Currency Mismatch – The Real Risk in African Infrastructure

In the first article in this series, I argued that Africa’s infrastructure challenge is not one of ambition or project availability, but of capital structure. In the second, I explored how infrastructure debt funds are emerging as a missing middle, aligning long‑term capital with long‑life assets.

There is, however, a deeper issue that continues to distort infrastructure investment decisions across Africa: how risk itself is defined and priced.

African infrastructure is routinely described as “high risk.” Yet this label has become a shortcut rather than a diagnosis. In practice, much of the perceived risk is not inherent to the asset or its operations. It is structural. The real risk in African infrastructure is not that assets fail to perform. It is that capital and currency are misaligned with the assets they finance.

Risk Is Being Misdiagnosed

Infrastructure risk is rarely singular. It includes construction risk, operational risk, demand risk, policy risk, financing risk, and currency risk. Too often, these are bundled together and labelled simply as “project risk.” This obscures more than it reveals. Across Africa, many infrastructure assets including power plants, transport corridors, ports, telecom towers, operate reliably once built. They generate essential services and predictable cash flows. When projects struggle financially, the problem is frequently not operational failure, but financial fragility. That distinction matters, because misdiagnosed risk leads to misapplied solutions.

Project Risk Is Not Financial Risk

Project risk concerns whether an asset can be built and operated as intended. Financial risk concerns how that asset is funded. In African infrastructure, financial risk often overwhelms sound project fundamentals. Commercial banks, constrained by short‑term liabilities and regulatory capital requirements, provide debt with maturities far shorter than the economic life of infrastructure assets. This introduces refinancing risk at precisely the wrong stage of an asset’s lifecycle. A project can be operationally sound and financially vulnerable at the same time.

The Currency Mismatch Problem

There is an even quieter source of instability: currency mismatch. Most African infrastructure revenues are earned in local currency. Much of the financing, particularly in early project stages, is denominated in foreign currency. This creates structural exposure to exchange‑rate volatility, independent of project performance. Currency movements, not demand failure, have been the primary driver of stress in many otherwise viable projects. Yet this is still described as “project risk.” It is not.

Why Banks and Governments Cannot Absorb This Risk

The persistence of this mismatch reflects structural limits. Commercial banks are not designed to hold long‑tenor currency risk at scale. Their balance sheets are short‑term by nature, and regulation reinforces this constraint. Governments, meanwhile, face fiscal limits, political sensitivity to contingent liabilities, and growing scrutiny over public debt. Absorbing long‑term infrastructure risk through sovereign balance sheets is increasingly untenable. Neither actor is structurally equipped to carry this risk over decades. That does not mean the risk disappears. It means it must be reallocated.

Risk Is Not Eliminated, It Should be Assigned

The objective in infrastructure finance is not to eliminate risk. It is to assign risk to balance sheets that can manage it. Long‑term institutional capital i.e. pension funds, insurance companies, dedicated infrastructure debt platforms etc., is structurally better aligned with infrastructure risk. Their liabilities are long‑dated. Their return expectations are stable. Their investment horizon matches the asset life. This is the logic underpinning infrastructure debt funds.

How Infrastructure Debt Funds Reframe Risk

Infrastructure debt funds do not make projects risk‑free. What they do is change the shape and location of risk. By matching asset life with capital life, they reduce refinancing risk. By diversifying across portfolios, they dilute asset‑specific shocks. By focusing on contracted cash flows rather than speculative upside, they prioritise resilience over volatility. Most importantly, they allow infrastructure risk to be priced, monitored, and held rather than repeatedly transferred through unstable refinancing cycles. In this sense, infrastructure debt funds are not just financing tools. They are risk‑management structures.

Comparative Perspective: How Others Addressed the Same Problem

Other emerging markets faced similar constraints. In India and parts of Latin America, infrastructure financing evolved when policymakers and investors accepted that the problem was not risk itself, but where risk sat. Long‑term debt platforms, refinancing of operational assets, and gradual reduction of foreign‑currency exposure allowed infrastructure risk to migrate from banks and governments to institutional balance sheets. The result was not risk elimination, but risk normalisation. Infrastructure ceased to be exceptional and became financeable at scale.

Nigeria as the Stress Test

Nigeria brings this debate into sharp focus. It has infrastructure assets with strong local‑currency demand. It has growing domestic institutional capital. It has improving PPP and regulatory frameworks. Yet financing structures have not consistently matched asset fundamentals. The question Nigeria now poses is not whether infrastructure is too risky. It is whether risk can be allocated to the right holders, using the right instruments, at the right tenor. If this can be done in Nigeria, it can be done elsewhere on the continent.

What Must Change in Investor Thinking

Investors often ask: Is this project risky? The more relevant question is: Is the capital structure fragile? This shift in perspective is subtle but decisive. It moves the conversation from avoidance to design, from fear to pricing, from rejection to structuring. Africa’s infrastructure future will be shaped not by those who avoid risk, but by those who understand where risk belongs.

Conclusion: Misalignment, Not Risk, Is the Real Constraint

Africa’s infrastructure challenge is not excessive risk. It is misplaced risk. When long‑term assets are financed with short‑term capital, when local‑currency revenues are paired with foreign‑currency debt, and when refinancing risk is treated as inevitable, failure becomes a financing outcome rather than an operational one. The next phase of African infrastructure finance will be defined by those who correct this misalignment. Risk is not the enemy. Misalignment is. And that is where the real work now lies.
