US proposed European countries unfreeze some Russian sovereign assets in an effort to revive peace talks during discussions in Miami last week between Trump's peace negotiators and officials from Ukraine, France, Germany, UK, EU and NATO, according to FT

The frozen sovereign assets question has been the most legally fraught thread of the sanctions regime since the reserves were immobilised: outright seizure has repeatedly been floated and resisted in Europe on rule-of-law and euro-custody grounds, while the compromise that actually advanced was the use of windfall profits rather than principal. A US proposal to partially unfreeze assets as a negotiating sweetener fits the established pattern of Washington treating the reserves as leverage for a settlement and European capitals treating them as their principal hold over Moscow; the reported rebuff is consistent with every prior round, where Europe has resisted moves that dilute the asset pool ahead of any deal. The actors matter here: the bulk of the reserves sit in European custody, so European assent is the binding constraint, and the US side cannot deliver unfreezing alone. Episodes of this kind have tended to trade through the peace-talks channel rather than the asset channel, with any credible thaw read as negative for European gas risk premia, gold and defence names, and positive for European equities and the euro; premature or rejected proposals have typically faded quickly. Worth noting is the sequencing tell: proposals floated through negotiators rather than formal communiques have historically been trial balloons, and the follow-on to watch is whether the idea resurfaces in official text or is denied. As a single-source report of a rejected proposal, the signal is directional and low conviction.
