Russia-Ukraine war: List of key events, day 1,388

Ukrainian forces said they retook parts of Kupiansk and encircled Russian troops as President Zelenskyy visited the front, while Kyiv stepped up strikes on Russian energy and maritime logistics—drones hit Lukoil’s Filanovsky and Korchagin Caspian rigs, Ukraine said it struck two Russian weapons ships and a major Yaroslavl refinery suspended output—Russia countered with strikes on Odesa and Chornomorsk ports (damaging Turkish-owned vessels) and reported shooting down some 90 drones. The EU agreed to indefinitely freeze €210bn of Russian sovereign assets to support Ukraine, prompting Moscow’s central bank to denounce the move as illegal and sue Euroclear, and Hungary lodged protests, raising legal and geopolitical frictions. Diplomatically, Turkey has urged an urgent ceasefire around ports and energy sites and President Erdogan raised limited ceasefire ideas with Putin, while US, EU and Ukrainian advisers (joined by private-sector figures including Ajay Banga and Larry Fink) discussed economic-track proposals such as a US-proposed Donbas free zone—yet the Kremlin conditions any ceasefire on full Ukrainian withdrawal from Donbas, leaving the prospect of a negotiated settlement and near-term energy and market risks uncertain.

Analysis

Ukrainian forces reported tactical gains around Kupiansk on day 1,388 (13 Dec 2025) with parts of the town retaken and Russian units reportedly encircled as President Zelenskyy visited the front; Kyiv has escalated maritime and energy-targeted strikes, saying SBU drones hit Lukoil’s Filanovsky and Korchagin Caspian rigs, struck two Russian weapons ships and attacked a major Yaroslavl refinery that industry sources say suspended output. Russia retaliated with strikes on Chornomorsk and Odesa ports that damaged three Turkish-owned vessels (including a civilian food ship), attacked energy infrastructure in Odesa region causing fires and outages, and reported shooting down 90 drones overnight; Sheremetyevo suspended departures and seven people were injured in Tver. The EU agreed to indefinitely freeze €210bn of Russian sovereign assets to support Ukraine, prompting Russia’s central bank to denounce the move as illegal and to sue Euroclear, while Hungary formally protested — a development that removes rollover ambiguity but raises legal and geopolitical countermeasures. Diplomatic activity is active but unresolved: Turkey urged a ceasefire around ports/energy and Erdogan discussed a limited ceasefire with Putin, the US proposed a Donbas free economic zone and a high-level meeting including Kushner, Witkoff, Ajay Banga and Larry Fink is working economic-track proposals, yet the Kremlin conditions any ceasefire on full Ukrainian withdrawal from Donbas, leaving short-term energy, shipping and sanction risks elevated; sentiment signals show strongly negative risk-off bias (sentiment_score -0.6, market_impact_score 0.65).

Key Decisions for Investors

• Reduce unhedged exposure to assets with direct Russia or Black Sea shipping/logistics exposure and consider hedging energy positions, given reported strikes on Lukoil rigs, a refinery suspension and damage to Turkish-owned vessels
• Avoid allocating to Russian sovereign or Euroclear-held assets until legal outcomes on the €210bn freeze and Moscow’s litigation are clearer, and maintain liquidity to respond to further escalation
• Monitor short-term indicators — oil and refined-product flows, shipping insurance/pandemic of port disruptions, and announcements on ceasefire scope — and use positive diplomatic progress around ports/energy as a catalyst to selectively redeploy capital
• Increase portfolio tail hedges or defensive positioning versus European logistics, insurers and energy names with high exposure to Black Sea routes while the security and sanction picture remains unsettled
