This SIPRI Fact Sheet presents the latest SIPRI data on multilateral peace operations, along with analysis of developments and trends in 2025.

• A total of 58 peace operations were active in 34 countries or territories during 2025. This was three fewer than in 2024.
• Personnel deployments to peace operations declined sharply to reach 78 633, just over half the number deployed in 2016 and the smallest number in at least 25 years.
• Sub-Saharan Africa, which saw the biggest personnel cuts, hosted 70 per cent of peace operation personnel in 2025.
• A combination of political, geopolitical and budgetary factors continued to challenge multilateral peace operations in 2025, at both United Nations and regional level.
• The cuts in deployed personnel during 2025 were largely driven by a liquidity crisis in the UN due to delayed or unpaid contributions from major donors.
• In the absence of multilateral responses to new and ongoing conflicts, the trend towards conflict management by ad hoc, often militarized bilateral or mini-lateral interventions continued in 2025.
