**Summary**: Ukraine reports striking 14 vessels in the Sea of Azov, including an oil tanker attempting to enter the Kerch Strait, marking the seventh consecutive day of this campaign. The sustained focus on tankers and regional shipping raises incremental risk to Russian oil logistics in the Black Sea and Azov corridors.

## Detail

1) What happened: Ukrainian Unmanned Systems Forces claim they struck 14 more ships overnight in the Sea of Azov, with the governor of Russia’s Rostov Oblast confirming that an oil tanker was hit while trying to enter the Kerch Strait. This forms part of a new Ukrainian campaign targeting Russian oil tankers and other vessels, now in its seventh consecutive day.

2) Supply/demand impact: The immediate physical loss of volumes from a single damaged tanker is minor in the context of global supply. However, the strategic impact lies in increasing risk and operational friction along a critical logistics artery for Russian oil and products moving between the Azov ports and the Black Sea, and ultimately to global markets. If insurers, charterers, and shipowners further reprice risk or restrict calls to Azov ports or transits via the Kerch Strait, effective export capacity from southern Russia could be constrained at the margin—potentially on the order of several hundred thousand barrels per day if disruptions broaden or repeat incidents mount.

3) Affected assets and direction: This development adds to the cumulative pressure on Russian oil export routes alongside ongoing drone strikes on refineries. Brent and Urals-related differentials are biased tighter, with Russian FOB discounts potentially widening on elevated logistical and insurance risk. Freight rates for tankers serving the Black Sea/Azov region may rise. European product cracks, especially diesel, could see modest support if market participants begin to price in heightened disruption risk to Russian exports.

4) Historical precedent: Previous Black Sea disruptions—such as the 2022–23 mines and corridor negotiations affecting grain—show that repeated incidents can materially alter routing, insurance, and capacity even in the absence of a formal blockade.

5) Duration: As this is the seventh straight day of attacks, the campaign appears deliberate and persistent. Expect a medium-term (weeks–months) elevation in risk premium for Russian southern export logistics, with the potential to escalate if tankers are sunk or navigation through Kerch is periodically halted.

**AFFECTED ASSETS:** Brent Crude, Urals FOB Black Sea, European diesel cracks, Tanker freight (Black Sea), Russia sovereign CDS
