Bulgaria became an EIB donor partner in 2019 after contributing funds to the Economic Resilience Initiative Fund (ERIF). The trust fund aims to build economic resilience and support sustainable growth in the Western Balkans and the EU's Southern Neighbourhood.
Donor partnerships provide an effective vehicle for donors looking to deliver sustained impact in developing countries. They enable donors to work with the EIB to unlock projects with high socio-economic returns, reaching out to people and places with additional support for targeted development outcomes. EIB activities outside the EU account for around one third of EU development aid. All contributions to EIB donor funds are considered Official Development Assistance (ODA) eligible.
