- •Advance warnings of impending strikes have in the past given Ukrainian authorities and residents time to prepare shelters and emergency responses.
- •The warning suggests increased military tensions that could lower the likelihood of a ceasefire agreement by the end of 2026, and market pricing indicates participants see a December 2026 deal as less probable.

Ukrainian President Volodymyr Zelensky has warned that Russia is planning a new mass attack, according to reports from the Jerusalem Post.
The announcement comes amid ongoing hostilities in the Russia-Ukraine war, which has featured repeated drone, missile, and glide-bomb strikes across Ukraine. Since Russia launched its full-scale in February 2022, Russian forces have regularly carried out large-scale barrages against Ukrainian cities, energy facilities, and other critical infrastructure, and Ukrainian officials have periodically cautioned in advance that further waves of strikes were being prepared. Those barrages have repeatedly tested Ukraine's air defenses, and strikes on power facilities have at times disrupted electricity and heating supplies for civilians.
Zelensky's statement raises concerns of a potential large-scale escalation, which typically involves coordinated attacks targeting civilian and infrastructure sites. Advance warnings of this kind have in the past given Ukrainian authorities and residents time to prepare shelters and emergency responses before strikes begin.
The development may further complicate diplomatic efforts aimed at securing a ceasefire agreement between the two nations. The warning appears to suggest an increase in military tensions, which could indicate a decreased likelihood of a ceasefire agreement by the end of 2026. The indication of a planned mass attack is also consistent with scenarios in which military activity intensifies, potentially affecting control over contested territories such as Sloviansk, a city in Ukraine's eastern Donetsk region that has remained under Ukrainian control.
Market pricing suggests that participants view the likelihood of a December 2026 ceasefire agreement as less probable in light of Zelensky's statement.
Several developments remain in focus, including any official responses from key actors such as the Kremlin, the U.S. government, and international bodies including the United Nations. Changes in military activity, particularly around strategic locations such as Sloviansk, could shape perceptions of the conflict's trajectory, while shifts in geopolitical dynamics or new diplomatic interventions will be important in assessing the potential for a ceasefire agreement before the end of the year.
