US Security Guarantee for Ukraine Unlikely by Deadline
U.S. agrees to give Ukraine security guarantee by June 30?
Polymarket prices this 100% no. The reporting broadly agrees.
The prospect of the United States formally committing to a NATO Article 5-style security guarantee for Ukraine by the June 30 deadline appears all but settled, with no such agreement anticipated. This effectively means that Kyiv will not receive a binding obligation from the Trump administration for direct military intervention on its behalf in the event of an attack. While the market has not officially closed, the outcome is considered a near-foregone conclusion, with traders putting the probability of "No" at 100%, a figure that has remained essentially flat with a +0.5 pts move over the past seven days.
Background
Discussions surrounding security guarantees for Ukraine have been ongoing, particularly in the context of potential peace agreements with Russia. Previous reports indicated that Russian President Vladimir Putin had agreed in principle to the idea of the US and Europe offering NATO-style security assurances to Ukraine, as conveyed by a Trump envoy. However, subsequent reports, including from Politico, suggested that the US would not provide such guarantees until a comprehensive peace agreement with Ukraine is finalized. The core issue revolves around defining a "security guarantee" equivalent to NATO's Article 5, which mandates mutual defense among members.
The precedent
- NATO's Article 5, established in 1949, states that an attack against one member is an attack against all, requiring collective defense.
- The Budapest Memorandum of 1994 provided security assurances to Ukraine from the United States, United Kingdom, and Russia in exchange for giving up its nuclear arsenal, though it did not include a binding mutual defense clause.
