The energy ceasefire between Russia and Ukraine was a short-lived and disputed arrangement described in October 2026 during the ongoing Russo-Ukrainian war. According to the supplied news context, U.S. president Donald Trump abruptly declared the ceasefire, although neither Russia nor Ukraine said that it had agreed to it.

The reported understanding concerned attacks connected with energy infrastructure. It collapsed after Ukraine resumed strikes on Russian oil refineries. Ukrainian president Volodymyr Zelenskyy said Kyiv was abandoning the ceasefire, while European Commission president Ursula von der Leyen said Russia had not respected it and had instead escalated attacks.

The episode occurred within the wider Russo-Ukrainian war, which began in 2014 and escalated sharply when Russia launched its full-scale invasion of Ukraine on 24 February 2022. It also formed part of continuing international efforts to negotiate a ceasefire or broader settlement, including initiatives pursued by the United States under the second Trump administration.
