Trader consensus prices "No" at 95% on any European country formalizing a bilateral security guarantee with Ukraine by June 30, reflecting the absence of active diplomatic negotiations or announcements among remaining EU member states or NATO allies in recent weeks. Over 28 such pacts were already signed by late 2025, shifting focus to multilateral frameworks like January's EU-U.S. pledges for post-war support, alongside €90 billion EU loans and $60 billion NATO weapons commitments highlighted at April's Ukraine Defense Contact Group. With just six weeks left and no reported talks on new bilateral deals—despite ongoing Ramstein meetings and aid packages—traders see significant procedural and political barriers. A sudden escalation or breakthrough with a smaller nation like Latvia could shift odds, though late formalization remains unlikely.

A qualifying “security guarantee” requires language that is equivalent in character to a NATO Article 5–style mutual defense commitment: the relevant European country must commit to responding militarily if Ukraine is attacked, or otherwise guarantee Ukraine’s defense through binding defense obligations. Examples of qualifying language include commitments modeled on the US treaties with Japan, South Korea, or the Philippines, or NATO's Article 5 instrument, which obligates the United States to “act to meet the common danger” through military force if an ally is attacked. Cooperative frameworks, capacity-building measures, consultative mechanisms, or nonbinding pledges will not qualify.
Examples of non-qualifying arrangements include the June 13, 2024 US–Ukraine bilateral security agreement, the Taiwan Relations Act, or G7/EU “security arrangements” that provide support or consultation but stop short of binding defense guarantees.
A qualifying agreement must be jointly announced and finalized, and take the form of a treaty, executive agreement, memorandum of understanding, joint declaration, or equivalent written instrument. Announcements which are statements of intent, contingent, exploratory, or otherwise not indicative of a formalized policy will not count.
The primary resolution source will be a consensus of credible reporting.
Qualifying European countries include: Albania; Andorra; Armenia; Austria; Azerbaijan; Belgium; Bosnia and Herzegovina; Bulgaria; Croatia; Cyprus; Czechia; Denmark; Estonia; Finland; France; Georgia; Germany; Greece; Hungary; Iceland; Ireland; Italy; Latvia; Liechtenstein; Lithuania; Luxembourg; Malta; Moldova; Monaco; Montenegro; Netherlands; North Macedonia; Norway; Poland; Portugal; Romania; San Marino; Serbia; Slovakia; Slovenia; Spain; Sweden; Switzerland; Ukraine; United Kingdom.
