Diplomatic expulsions of U.S. ambassadors remain rare events triggered only by acute bilateral crises, such as major policy clashes or public insults. As of May 2026, no such rupture has materialized despite isolated calls in South Africa and Lebanon for action against sitting envoys. These remain rhetorical amid otherwise routine diplomatic engagement. U.S. relations with key partners show no escalation to persona-non-grata declarations, with tensions instead addressed through recalls, statements, or standard channels. The 73% market probability for no expulsion by year-end reflects this absence of fresh catalysts capable of prompting a host government to cross that threshold within the remaining timeline.

Qualifying announcements must be definitive, unambiguous, official statements issued by an authorized governmental person or entity.
Whether the ambassador resigns, is recalled, or otherwise departs voluntarily will have no bearing on the resolution of this market.
