**Summary**: Ukraine has conducted another drone strike on Russia’s Tuapse oil refinery in Krasnodar Krai, with reports ranging from one damaged tank to multiple tanks ablaze. This is the latest in a series of attacks on the facility, reinforcing downside risk to Russian product exports and supporting the current risk premium in crude and products.

## Detail

1) What happened:
Multiple Ukrainian reports (15, 17, 32, 35, 34) confirm a renewed drone strike on the Tuapse refinery overnight, with claims of at least four tanks set ablaze. Russian media are downplaying the incident, saying only one tank was damaged (33). This follows previous attacks on the same refinery, and Ukraine’s General Staff has explicitly framed this as a deliberate repeat strike (11, 15). The facility is an export-oriented refinery on the Black Sea, important for Russian product flows.

2) Supply impact:
While precise damage and downtime are not yet confirmed, the pattern of repeated strikes suggests disrupted operations and/or forced curtailments even if physical damage is localized. Conservatively, markets will assume elevated outage risk and a higher probability of more effective future strikes, including on associated storage and port logistics. Tuapse has nameplate capacity of ~240 kb/d; even a partial loss or precautionary run cut of 25–50% for several weeks equates to 60–120 kb/d of refined product potentially removed or delayed from seaborne markets. Coupled with other ongoing disruptions to Russian export infrastructure, this incrementally tightens product balances, especially for fuel oil, vacuum gasoil, and diesel flows to Europe, the Mediterranean, and West Africa.

3) Affected assets and direction:
This materially reinforces upside pressure on Brent and gasoil cracks, and supports backwardation in refined product curves. The continuation and escalation of attacks at the same site increases the perceived vulnerability of Russian Black Sea export infrastructure more broadly, adding to risk premia already priced after earlier Tuapse strikes (existing alerts) but likely still capable of pushing front-month Brent and European diesel >1% on confirmation of extended downtime.

4) Historical precedent:
Past repeated strikes on Russian refineries (e.g., 2024–25 wave of drone attacks) reliably added 1–3% to front-month crude and significantly widened diesel and fuel oil cracks when sustained outages were anticipated, even when physical damage was limited but operational risk rose.

5) Duration:
Direct physical disruption may be weeks to a few months depending on damage, but the structural effect is a higher ongoing risk premium for Russian product exports as Ukraine demonstrates persistent long-range strike capability against coastal refining assets.
