Africa’s Infrastructure Capital Constrained by Allocatability

A new analysis released by the Sustainable Markets Initiative (SMI), Africa investor (Ai), the Institute of Sovereign Investors (ISI), and partners suggests that the primary constraint on infrastructure capital formation may no longer be capital availability, but rather allocatability. This shift highlights the growing importance of aligning infrastructure projects with institutional investor mandates, as more than US$300 trillion is already allocated across institutional portfolios worldwide, yet the infrastructure financing gap persists.
The report, released ahead of the G7 Summit and London Climate Action Week, argues that despite three decades of guarantees, blended finance structures, political risk insurance, and first-loss capital mechanisms, the global infrastructure financing gap remains substantial. This persistence shows the need to reevaluate the traditional focus on risk reduction and explore new frameworks like Allocatability Risk-Bounding (ARB) to address the evolving challenges in infrastructure financing.
The Shift from Bankability to Allocatability
According to the analysis, the challenge is no longer simply how to finance infrastructure, but how to create allocatable exposure. The infrastructure constraint is increasingly fiscal rather than financial. Governments, which traditionally scale infrastructure through balance sheets, now face requirements that exceed their fiscal capacities and the mobilization potential of MDB-led de-risking mechanisms. This fiscal strain necessitates a rethinking of how infrastructure projects can meet the stringent allocation criteria of institutional investors.
Governments face infrastructure requirements that exceed what public balance sheets can fund and what MDB-led de-risking mechanisms can mobilize at scale. As fiscal capacity becomes increasingly constrained, infrastructure capital formation may depend less on additional risk-transfer mechanisms and more on whether infrastructure exposure can satisfy institutional allocation requirements at scale. The focus must shift from merely de-risking projects to ensuring they align with the benchmarks and governance frameworks of institutional portfolios.
Bankability determines whether projects obtain financing, while allocatability determines whether exposure can enter the portfolio, benchmark, and governance systems through which institutional capital is allocated. These conditions are not equivalent, and the distinction is critical for understanding why financially viable projects often fail to attract institutional investment.
The Role of Institutional Investors
Institutional investors scale infrastructure through allocations, not projects. They allocate to admissible exposure, not individual projects. This distinction is key, as projects may satisfy lender requirements, attract financing, and achieve commercial viability while remaining absent from institutional portfolios. The analysis emphasizes that institutional capital allocation is driven by exposure characteristics rather than project-specific merits, further highlighting the need for infrastructure projects to align with broader portfolio criteria.
The analysis introduces the concept of Allocatability Risk-Bounding (ARB), which addresses the conditions through which infrastructure exposure becomes institutionally allocatable. By understanding the relationship between infrastructure development, institutional participation, and long-term capital formation, sovereigns, investors, and policymakers can better mobilize capital at institutional scale. ARB provides a structured approach to bridge the gap between bankability and allocatability, ensuring that infrastructure projects not only secure financing but also meet the allocation requirements of institutional investors.
As Dr. Hubert Danso, Chairman and Chief Executive Officer of Africa investor Group, notes: “For decades, infrastructure finance has focused on reducing risk in order to attract capital. Yet the financing gap persists despite significant innovation in guarantees, blended finance, and risk-transfer mechanisms.” Dr. Danso further emphasizes that the challenge is no longer about removing more risk but about creating allocatable exposure, a paradigm shift that requires a deeper understanding of institutional investor behavior and portfolio construction disciplines.
The challenge is not capital availability, but institutional allocatability. As fiscal capacity becomes increasingly constrained, the question is no longer simply how to finance infrastructure, but whether infrastructure exposure can become allocatable. This shift necessitates a reevaluation of traditional financing strategies and a focus on aligning infrastructure projects with the mandates and benchmarks of institutional investors.
In practice, this shift means that infrastructure projects must not only be financially viable but also align with the mandates, benchmarks, and governance frameworks of institutional investors. This alignment is essential for attracting the large-scale capital needed to address the global infrastructure gap. Projects that fail to meet these criteria risk being excluded from institutional portfolios, regardless of their financial viability or risk profile.
Implications for Sovereigns and Policymakers
As Kristian Flyvholm, Chief Executive Officer of the Institute of Sovereign Investors (ISI), explains: “The world’s largest pools of capital allocate through mandates, benchmarks, governance frameworks, and portfolio construction disciplines.” Flyvholm highlights that understanding these disciplines is key for sovereigns and policymakers to effectively mobilize institutional capital for infrastructure development.
A project may satisfy lender requirements and still remain absent from institutional portfolios. Infrastructure may be bankable without being allocatable. Allocatability provides a useful lens through which sovereigns, investors, and policymakers can better understand the relationship between infrastructure development, institutional participation, and long-term capital formation. This lens reveals the critical differences between what makes a project financially viable and what makes it institutionally allocatable.
The analysis suggests that infrastructure capital may increasingly scale not because risk disappears, but because exposure becomes institutionally allocatable. As fiscal capacity becomes increasingly constrained, understanding the distinction between bankability and allocatability may become increasingly important for sovereigns, investors, and policymakers seeking to mobilize capital at institutional scale. This understanding is vital for designing infrastructure projects that not only secure financing but also align with the allocation criteria of institutional investors.
The report is being released as leaders, sovereigns, investors, and policymakers gather for the G7 Summit and London Climate Action Week to identify practical mechanisms capable of accelerating private capital mobilization for resilient infrastructure systems. Its central proposition is straightforward: bankability determines participation, allocatability determines scale, and scale determines the cost of capital. By focusing on allocatability, stakeholders can unlock the vast pools of institutional capital needed to address the global infrastructure gap and support sustainable development.
