**Summary**: Ukraine has formally ended its pause on strikes against Russian oil infrastructure, with reports of a fresh attack setting the Ryazan refinery ablaze and the Kremlin confirming continued hits on energy facilities. This reopens the risk of recurring outages at key Russian refining assets, raising global diesel/gasoline supply concerns and re‑pricing the geopolitical risk premium in crude and refined products.

## Detail

Multiple reports in the last hour indicate that Ukraine has officially resumed strikes on Russian oil refineries after a short‑lived ‘energy ceasefire’ expectation. A specific strike reportedly set the Ryazan refinery ablaze, and both Ukrainian and Kremlin statements confirm an intent by Kyiv to continue targeting Russian energy infrastructure, including refineries. This is being framed as a deliberate, open‑ended campaign rather than isolated one‑off attacks.

On the supply side, Russia is one of the world’s largest exporters of diesel and other refined products. Earlier in the conflict, Ukrainian drone and missile attacks temporarily knocked 10–15% of Russian refining capacity offline at different points, tightening middle distillate balances and lifting diesel cracks. A renewed, politically signaled campaign against refineries increases the probability of sustained or recurring outages in the low‑to‑mid double‑digit percent range of Russian refining capacity over coming months, depending on strike frequency and repair times.

The immediate market impact is to add a risk premium to crude (Brent and Urals) and, more acutely, to European diesel and global middle distillates. Russian diesel exports to global markets are explicitly referenced as resuming, which had been stabilizing prices; renewed refinery disruption could reverse that effect, tightening European and global diesel spreads versus crude. Front‑month cracks and time spreads are likely to widen, with the largest move in European gasoil futures and regional physical diffs. Tanker routing risk in the Black Sea also edges higher as refineries and associated logistics are targeted.

Historically, similar Ukrainian campaigns against Russian refineries in early 2024–2025 pushed refining margins and diesel prices higher even when headline crude prices were range‑bound, as markets repriced the availability of Russian product exports. The current signals—public political commitment by Zelensky to continue the strikes and Kremlin confirmation of ongoing hits—suggest this is not transitory headline risk but a structural medium‑term threat to Russian refining reliability.

Expected duration of impact is at least several weeks to months, contingent on the scale and success of further strikes. The risk skew is bullish for refined products and modestly bullish for crude, with upside to European inflation expectations and potentially to European power prices via fuel‑switching if gas markets tighten seasonally.
