Russia's nuclear posture remains shaped by ongoing strategic signaling amid U.S. statements on resuming explosive testing after decades of moratorium. President Putin has publicly warned of reciprocal measures if Washington proceeds first, while Russian forces continue large-scale exercises involving strategic missile launches, bomber patrols, and nuclear command drills without crossing into actual explosive tests. Activity at the Novaya Zemlya site and doctrinal updates lowering nuclear thresholds have sustained trader attention, yet no verified detonation has occurred since the Soviet era. Escalation risks tied to the Ukraine conflict and U.S.-Russia diplomatic frictions keep the possibility open, though historical restraint and verification challenges support the market's low implied probabilities for near-term tests by specific deadlines. Scheduled military maneuvers and any further U.S. policy moves could influence sentiment before year-end resolution windows.
