Abstract
Emerging economies face widening development-financing gaps amid constrained public revenues and rising debt burdens. In 2024, debt servicing absorbed over 70% of Nigeria’s federal revenue, sharply limiting fiscal space for infrastructure, health, education, and climate objectives. This paper examines how legal and regulatory frameworks can mobilise private capital while guaranteeing public mandates. The findings demonstrate that comprehensive PPP legislation, legally-backed guarantees, and predictable fiscal regimes directly influence investor confidence and deal flow. Comparative evidence from Kenya and Ghana substantiate the unbroken link between clear statutory mandates, institutional coordination and stronger project pipelines. In the same vein, Nigeria’s InfraCredit demonstrates how institution-backed guarantees unlock domestic capital markets. Empirically, climate finance remains underfunded (only $1.9 billion flowed annually in 2019–2020 against a $17.7 billion need), with private sources contributing just 18%. Furthermore, education and health sectors lag due to regulatory and procurement gaps. The paper recommends harmonised PPP reforms, stronger statutory backing for guarantee institutions, standardised transaction models, performance-based incentives, and enhanced oversight. These measures unequivocally address sectoral disparities and limited private participation. It concludes that blended finance functions best when paired with legal certainty, transparency, and enforceable accountability. These requisites align private incentives with public mandates at scale.
