The United Nations Capital Development Fund (UNCDF) serves as the United Nations’ flagship catalytic financing platform, designed to crowd-in the public-private finance needed to scale development impact where needs are the most acute and constraints to private investment are the most pervasive, particularly in Least Developed Countries (LDCs). By leveraging a combination of concessional financing instruments, advisory services, and technical assistance, UNCDF is strategically positioned in the UN Development System (UNDS) – and complementary to UNDP – to catalyze public and private investment at the speed, agility, and scale needed to achieve the Sustainable Development Goals (SDGs) and realize the Doha Programme of Action for the Least Developed Countries, 2022–2031.
