What’s Happening

Negotiations over a potential European country agreeing to give Ukraine a security guarantee by December 31 remain fluid, with the probability of a formal bilateral pact by that date standing at just 10%. The most concrete development occurred on December 15, when the Council of the European Union issued a joint statement affirming that European nations and the United States would provide “robust security guarantees” to Ukraine as part of a broader peace framework. That statement, however, stopped short of naming a single European country as the lead guarantor, instead describing a collective commitment alongside economic recovery measures. The Council’s language followed a December 11 meeting of European leaders in Paris, where French President Emmanuel Macron and German Chancellor Olaf Scholz discussed structuring guarantees that would not trigger immediate NATO membership but would still deter further Russian aggression.

The core obstacle to any european country agreeing to give ukraine security guarantee by december 31 is Russia’s explicit refusal to accept an arrangement where Moscow is not a co-guarantor. According to a December 15 analysis from Defense Priorities, Russian negotiators have indicated they will reject any security guarantee framework that excludes them, while Ukrainian President Volodymyr Zelensky has insisted that guarantees must be binding and enforceable without Russian participation. Meanwhile, a December 31 post by U.S. envoy Steve Witkoff described “productive” discussions with national security advisers from Britain, France, Germany, and Ukraine focused on “strengthening security guarantees and developing effective deconfliction mechanisms.” That post, however, did not confirm a bilateral treaty, and subsequent meetings in Paris on January 6 produced no public breakthrough, with France 24 reporting that progress remains uncertain as Russia shows no signs of budging from its demands.

The structural factor that will determine whether any european country agrees to give ukraine security guarantee by december 31 is the timeline for the €90 billion EU financial support package, which the European Council agreed in December 2025 to disburse across 2026 and 2027. That package, representing two-thirds of Ukraine’s funding needs, is explicitly tied to defense industrial investment and military equipment procurement, but the Council directed that the loan should only become repayable once Russia has made war reparations — a condition Moscow has rejected. European leaders have linked the security guarantee question to this funding mechanism, suggesting that a formal bilateral guarantee may be delayed until the financial framework is operational. With the December 31 deadline now passed without a confirmed bilateral agreement, the market’s 10% probability reflects the gap between collective EU statements and the legally binding, single-country guarantee that Ukraine has sought.
