U.S. agrees to give Ukraine security guarantee by June 30?

Platform comparison

Market context

The United States has formally proposed a 15-year security guarantee for Ukraine as part of a condensed 20-point peace framework, a move confirmed by President Zelenskyy following his meeting with President Trump at Mar-a-Lago on Sunday[2][3]. This represents a significant shift from earlier statements by Trump, who previously insisted Europe must underwrite Ukraine’s security and denied any significant US commitment[4]. Despite this new offer, the market-implied probability of a binding, NATO Article 5-style guarantee by June 30 remains at 0%, reflecting deep scepticism that the proposal will satisfy the market’s strict definition of a mutually agreed, binding obligation before the settlement deadline.

Historically, comparable security arrangements, such as those discussed during the 2026 Geneva and Abu Dhabi meetings, have stalled due to Russian insistence on full control of Donbas and unresolved issues regarding the Zaporizhzhia nuclear facility[6]. The Razumkov Centre notes that while robust guarantees are a prerequisite for peace, they remain a major obstacle, with Russia yet to accept the terms proposed by the US, Europe, and Ukraine[5]. The current 0% probability mirrors these past failures, suggesting that a 15-year offer, which Zelenskyy himself argued should be extended to 50 years for true deterrence, does not equate to the binding, Article 5-equivalent commitment required for a “Yes” resolution[2][3].

Traders should monitor the immediate reaction from the Kremlin, as Russia has so far rejected the 20-point proposal, and watch for any US Congressional vote, which Zelenskyy noted is required to ratify the guarantee[3]. Key catalysts include the finalisation of security protocols in Paris, where US envoy Steve Witkoff claimed significant progress was made, and any announcement regarding the multinational force composition, which currently lacks clarity on US troop involvement[1]. The settlement window closes on 30 June 2026, leaving little time for Russia to reverse its stance or for the US to secure the necessary legislative approval for a binding obligation[1][3].
