A new analysis suggests that infrastructure capital formation is increasingly constrained by allocatability rather than capital availability, despite more than $300 trillion being allocated across institutional portfolios worldwide. The global infrastructure financing gap remains substantial, even after three decades of guarantees, blended finance structures, political risk insurance, and first-loss capital mechanisms.
The infrastructure challenge is no longer simply how to finance infrastructure, but how to create allocatable exposure, according to the analysis released by the Sustainable Markets Initiative, Africa investor, the Institute of Sovereign Investors, and partners.
Understanding Allocatability
Infrastructure may be bankable without being allocatable, and the infrastructure constraint is increasingly fiscal rather than financial, the analysis notes. Governments face infrastructure requirements that exceed what public balance sheets can fund and what MDB-led de-risking mechanisms can mobilise 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. 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.
Allocatability Risk-Bounding
Allocatability Risk-Bounding (ARB) addresses the conditions through which infrastructure exposure becomes institutionally allocatable. The analysis 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 mobilisation for resilient infrastructure investment systems.
According to the report, the central proposition is straightforward: bankability determines participation, allocatability determines scale, and scale determines the cost of capital. Dr Hubert Danso, Chairman and Chief Executive Officer of Africa investor Group, notes that the challenge is not capital availability, but institutional allocatability.

Dr Hubert Danso, Chairman and Chief Executive Officer of Africa investor Group, notes that “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.The challenge is not capital availability. The constraint is institutional allocatability. Governments scale infrastructure through balance sheets. Institutional investors scale infrastructure through allocations. As fiscal capacity becomes increasingly constrained, the question is no longer simply how to finance infrastructure. The question is whether infrastructure exposure can become allocatable. Institutional portfolios do not primarily allocate to projects. They allocate to admissible exposure. The challenge is no longer how to remove more risk. It is how to create allocatable exposure.”
Kristian Flyvholm, Chief Executive Officer of the Institute of Sovereign Investors (ISI), adds that 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.
Implications for Infrastructure Capital
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 mobilise capital at institutional scale.
The analysis highlights the need for a new approach to infrastructure financing, one that focuses on creating allocatable exposure rather than simply reducing risk. By understanding the conditions through which infrastructure exposure becomes institutionally allocatable, sovereigns, investors, and policymakers can work towards accelerating private capital mobilisation for resilient infrastructure systems.
