European leaders have advanced planning for a multinational reassurance force to support Ukraine's security after any ceasefire, with the UK and France coordinating a coalition of the willing that includes commitments from dozens of nations for air, land, and sea elements. A letter of intent was signed in January 2026, and recent NATO and EU meetings have emphasized sustained support and coordination ahead of potential deployment. Stalled U.S.-mediated talks have shifted focus to European diplomacy, including early June 2026 discussions among UK, German, French, and Ukrainian leaders on security guarantees. Russia continues to reject NATO or EU troops on Ukrainian territory, while formal peace negotiations remain limited. Trader sentiment reflects the conditional nature of any announcement, tied to progress on ceasefires and territorial issues.
