Over the past decade, about three-quarters of private infrastructure investment globally was debt financed, and about a quarter was equity financed.
In private infrastructure investments, equity financing is typically higher than debt financing to compensate for higher intrinsic risk. Over the past decade, equity financing was relatively higher in lower middle- and low-income country groups, and the regions of Asia Pacific and Sub-Saharan Africa. Across infrastructure sectors, equity financing was relatively higher in the water and waste, and transport infrastructure sectors.
