Ukrainian sea drone sets a laden crude tanker ablaze off Sochi
A Liberian-flagged crude tanker was struck by a sea drone off Sochi on the evening of 6 October. All 23 Indian crew members were rescued; Russia's transport ministry said the oil was burning on the sea with an open flame.
Arab News reported on 7 October that the attack took place on the evening of Tuesday 6 October and thick smoke rose over Sochi, a city of about 500,000. According to Georgia Today, Russia's transport ministry confirmed the attack and said firefighting would begin once the flames died down. The tanker's name and the size of its cargo had not been officially disclosed as of 7 October. On 7 October Zelensky said four targets had been hit in 24 hours and that a response had also been delivered in the Black Sea.
The attack shows that the war on shipping in the Black Sea now runs in both directions. Turkish Minute reported that three Turkish-owned ships were hit by drones off Romania and Bulgaria on 5–6 October, and two sank. According to Euronews, Zelensky blamed Russia for the sinking on 5 October, while Bulgaria named no culprit for the attack on 6 October. NBC News said Ukraine also hit oil facilities in Perm, Samara and Astrakhan in the same 24 hours. With this attack, the risk now extends to Novorossiysk, Russia's main crude export route in the Black Sea.
The constraint is insurability. Dünya newspaper reported on 21 September that the Black Sea war-risk premium had risen from a normal 0.1–0.2% of a ship's value to 1–1.5%. At that rate a seven-day voyage carries an extra cost of $150,000–300,000. Now that tankers calling at Russian ports are targets on the open sea too, the premium is expected to be repriced; the new rate could not be verified as of 7 October.
Talay assessment
Bottom line
The Sochi attack confirms that the risk to merchant shipping in the Black Sea now runs both ways: in three days three Turkish-owned ships and one tanker bound for a Russian port were hit. The war-risk premium is already 1–1.5%, and a further rise for tankers on Russian routes is likely. The most likely path is that Black Sea freight becomes more expensive for everyone, Turkish shipowners included.
Likely effects
- Black Sea freight and insuranceNegativeWeeks
The war-risk premium for tankers bound for Russian ports could rise above the 1–1.5% band, adding to the $150,000–300,000 extra cost of a seven-day voyage.
- Turkish shipownersNegative1–6 months
Turkish shipowners, three of whose vessels were hit on 5–6 October, face higher premiums and crew risk on routes now targeted by both sides.
- Russian crude exportsNegative1–6 months
If chartering tankers on the route to Novorossiysk becomes costlier, Russian crude will be sold at deeper discounts and budget revenue will fall.
Possibilities, ranked
- 1Tit-for-tat attacks on shipping continue55%
At least one more attack on a merchant ship occurs in the Black Sea in October and insurers reprice regional premiums.
