Multilateral development banks (MDBs) are "institutions that provide financial support and professional advice for economic and social development activities in developing countries."1 The largest of these include banks from the World Bank Group along with the following four regional development banks: the African Development Bank (AfDB), the Asian Development Bank (ADB), the European Bank for Reconstruction and Development (EBRD), and the Inter-American Development Bank (IADB) Group. MDBs occupy a unique position: they not only provide finance for infrastructure projects, but their multinational ownership structure and pan-regional outlook mean that they can provide an important bridge between the public and private sectors.
