Russia says it hit a tanker off Odesa, two days after earlier strikes
Russia's defence ministry said on 10 November, as reported by Interfax, that it had struck a dry bulk carrier and a tanker in the Black Sea and a second dry bulk carrier east of Odesa. It is the second wave after a claim of three ships on 8 November; none has been independently verified.
According to a Reuters-sourced report published by Business Recorder on 10 November, the ministry did not give the names, flags, owners or cargoes of the targets. There was no initial comment from Ukraine, and no information on casualties or damage. The Russian ministry had also said on 8 November that it struck three ships around Odesa and Chornomorsk; Reuters could not verify that claim either.
The campaign is not new. An Atlantic Council piece dated 18 August said Odesa officials had by then counted more than 70 attacks on port infrastructure and more than 60 on commercial vessels. The same piece said Odesa and two neighbouring ports normally handle about 60% of monthly exports, cargo worth roughly 3.5 billion dollars. Those counts date from August and are stale. The claim that a tanker was targeted suggests the strikes are extending from dry bulk to energy shipping.
Current war risk premium quotes for tankers calling at Ukrainian ports could not be verified. According to Talay's record of 28 September, Ambrey counted 45 merchant ships hit outside the former risk zone in the 12 months to 21 September. As the tempo rises to several ships a week, the cover threshold becomes the real variable deciding which shipowners keep using the corridor.
Talay assessment
Bottom line
Russia has claimed six ships in two days and added a tanker to its target list. The claims are unverified, but successive announcements keep cover for ships bound for Ukrainian ports expensive and conditional. The corridor closes not through price but when underwriters stop offering cover, and that threshold does not appear to have been crossed yet.
Likely effects
- Black Sea insuranceNegativeWeeks
A tanker on the target list could make war risk cover for energy cargoes dearer than for dry bulk; the thesis fails if quoted premiums fall.
- Ukrainian exportsNegativeWeeks
Sustained targeting of the port cluster that carries about 60% of monthly exports raises freight costs and shipping delays.
- TürkiyeUncertain1–6 months
Attacks on shipping in the Black Sea add to Ankara's chokepoint security initiative and to its diplomatic burden over the Straits.
