**Summary**: Ukraine has formally ended its pause on attacks against Russian refineries, with confirmed new strikes setting at least the Ryazan refinery ablaze and the Kremlin acknowledging ongoing hits to energy infrastructure. This renews the risk of incremental Russian product export losses and a higher geopolitical risk premium in refined products and crude.

## Detail

Multiple reports in the last hour confirm that Ukraine is resuming systematic strikes on Russian oil infrastructure. Zelensky and Ukrainian officials publicly state that attacks on refineries will continue, while Russian and Kremlin-linked channels acknowledge ongoing strikes on energy facilities. A specific incident is flagged at the Ryazan refinery, which has been set ablaze, implying at least temporary operational disruption.

Russia is the world’s largest seaborne exporter of diesel and a major exporter of other refined products. Previous waves of Ukrainian drone/missile attacks on Russian refineries in late 2023–2025 periodically removed an estimated 300–800 kb/d of refining capacity for weeks at a time, causing spikes in European diesel cracks and supporting Brent. A renewed campaign, explicitly framed as open-ended, increases the probability of recurring outages across the Russian refining system heading into the Northern Hemisphere winter.

Immediate supply-side impacts are twofold: (1) potential loss of Russian refined product exports, particularly diesel and naphtha, if significant units at targeted plants are damaged or pre-emptively shut for protection; and (2) possible upstream impacts if sustained refinery outages force Russia to curtail crude runs, leading to marginally higher crude exports but tighter product balances. In practice, past episodes showed net bullish effects for refined product benchmarks and a modest positive risk premium for Brent/WTI via concerns over global product tightness.

Market reaction should center on European diesel futures, gasoline and middle distillate cracks, and Urals/ESPO differentials. European gasoil and Singapore middle distillates are likely to gain, with Brent and WTI supported by 1–3% in the near term on higher geopolitical risk and potential product shortage fears. Shipping rates for clean tankers in the Atlantic and Med could also firm on rerouting and substitution flows.

Historically, such campaigns had an episodic but recurring effect: price spikes on each major hit, then partial normalization as capacity returns or flows are rerouted. The new rhetoric—openly rejecting an “energy ceasefire” and signaling continued strikes—shifts this from a one-off shock to a structurally higher tail-risk environment for 2026 winter. Expect the impact to be medium-duration (weeks to months), with volatility around each confirmed high-capacity refinery strike.
