Development finance institutions (DFIs) occupy an intermediary space between public aid and private investment, ‘facilitating international capital flows’ … Distinct from aid agencies through their focus on profitable investment and operations according to market rules, DFIs share a common focus on fostering economic growth and sustainable development. Their mission lies in servicing the investment shortfalls of developing countries and bridging the gap between commercial investment and state development aid (http://www.oecd.org/dev/41302068.pdf).
 
There are numerous DFIs including multilateral development banks (including World Bank and Asian Development Bank); regional development banks (including African Development Bank and European Bank for Reconstruction and Development); bilateral development banks (including German Investment Corporation) and Bretton Woods Institutions (including the International Monetary Fund).
