The UN Secretary-General’s Peacebuilding Fund (PBF) is the organization’s financial instrument of first resort to sustain peace in countries or situations at risk or affected by violent conflict. The PBF may invest with UN entities, governments, regional organizations, multilateral banks, national multi-donor trust funds or civil society organizations. From 2006 to 2020, the PBF has allocated nearly $1.47 billion to 62 recipient countries. Since its inception, 60 member states contributed to the Fund, and 42 have made commitments and pledges for the present 2020-2024 Investment Plan. The Fund works across pillars and supports integrated UN responses to fill critical gaps; respond quickly and with flexibility to peacebuilding opportunities; and catalyze processes and resources in a risk-tolerant fashion.
