Quality infrastructure is central to sustainable socio-economic development. Despite its critical importance, however, infrastructure globally suffers from an investment gap of $2.5-3 trillion per annum.
This policy paper catalogues tools and techniques used by public actors such as national development banks and green investment banks to mitigate project-level risks and attract private investment in infrastructure. The analysis provides development banks and other public financial institutions a nuanced view of options for targeted mobilisation efforts.
The paper updates the dataset underlying the 2018 "Progress Update on Approaches to Mobilising Institutional Investment for Sustainable Infrastructure" to provide an expanded typology of de-risking instruments and highlight several novel approaches for mobilising institutional investment.
