International peacekeeping missions are in peril due to global geopolitical deadlock, funding issues and declining personnel numbers, the Stockholm International Peace Research Institute (SIPRI) said Monday.

Missions managed by the United Nations have been particularly affected, a SIPRI study said.

The analysis found that just under 79,000 personnel were deployed in international peacekeeping missions at the end of 2025, its lowest point in 25 years and 49% lower than in 2016.A 'perfect storm'

"If things continue in this way, we could see a dramatic weakening of multilateral conflict management and the near-complete sidelining of institutions like the United Nations," said Jair van der Lijn, SIPRI's director of peace operations and conflict management programme.

"The result is likely to be more conflicts, and these conflicts are likely to have even graver impacts on civilians as states abandon long-established norms," van der Lijn added.
