Russian President Vladimir Putin’s October 1 rejection of mutual limits on long-range strikes against energy infrastructure and shipping has reinforced trader expectations of continued fighting, following intensified Russian drone and missile barrages on Ukrainian cities and reciprocal Ukrainian attacks on Russian refineries. US-mediated efforts since September, including proposals for limited energy, grain, and Black Sea truces discussed at the UN General Assembly and a possible October trilateral technical meeting in the UAE, have produced only rhetorical openings from Moscow while Putin insists any agreement must address core security demands and territorial outcomes. Ongoing strikes, differing positions on neutrality and occupied regions, and Putin’s recent comments on a potential future memorandum after a Trump call highlight persistent gaps that limit near-term ceasefire prospects despite diplomatic activity.
