Risk assessment

Risk profile

The 12-month probability of a new armed-conflict onset in Brunei is 0.2%, representing a minimal risk. Brunei’s long period without civil war, insurgency, or interstate fighting; small population; effective state institutions; and substantial energy revenues support a highly stable security environment.

Recent reporting provides no evidence of armed mobilisation, domestic unrest, or threats to Brunei’s territory. A September 2026 report noted the presence of U.S. F-22 personnel at Rimba Air Force Base in August 2024, illustrating defence cooperation rather than an emerging conflict. No prediction market is available for Brunei.

The main uncertainty is whether a wider regional confrontation could eventually reach Brunei through miscalculation or attacks affecting its territory, although no such pathway is currently evident. Risk would rise most clearly with sustained domestic armed violence, a serious breakdown in political order, or an interstate attack; continued institutional stability and routine defence cooperation would support the current minimal assessment.

Strategic reasoning

  • Brunei’s conflict-free modern history, strong state capacity, and hydrocarbon-funded public finances reduce the likelihood that political grievances develop into sustained armed violence.
  • The reported U.S. military presence at Rimba Air Force Base is a stabilising defence relationship, while the absence of reported armed mobilisation or domestic unrest provides no current escalatory signal. Fighting involving Brunei abroad would not itself constitute a new onset on Bruneian territory.

Critical indicators

  • In August 2024, U.S. F-22 personnel from the 27th Expeditionary Fighter Squadron visited Rimba Air Force Base in Brunei; the development indicates established defence cooperation, not conflict on Bruneian territory.
  • A 7 September 2026 report discussing China’s J-20 and J-35 aircraft referenced the earlier U.S. presence in Brunei but identified no attack, mobilisation, or armed confrontation involving Brunei.
