The Western Balkans Investment Framework (WBIF) is a regional blending facility supporting EU enlargement and socio-economic development in Albania, Bosnia and Herzegovina, Kosovo*, the former Yugoslav Republic of Macedonia, Montenegro, and Serbia. 

The WBIF was established in 2009 as a joint initiative of the European Commission, the Council of Europe Development Bank, the European Bank for Reconstruction and Development, the European Investment Bank, and and several bilateral donors. The World Bank Group and the KFW Development Bank subsequently joined the Framework. In June 2017, the KfW became partner organisation to the WBIF. 

The WBIF provides financing and technical assistance to strategic investments in the energy, environment, social, and transport sectors. It also supports private sector development initiatives.
