A wider underwriting boundary
The London market’s Joint War Committee widened its Black Sea listed area on 16 September. The new boundary now covers almost the whole sea for hull war, piracy and terrorism risks, excluding the territorial waters of adjoining states other than Russia and Ukraine. Its immediate effect falls on insurance administration. The wider boundary brings more voyages into an area that can trigger notification, underwriting review and contract-specific negotiation.
That distinction matters for Ukraine and Romania. Ships serving Ukrainian ports remain within the listed area through Ukrainian territorial waters. Romania’s territorial waters fall outside it. Many international voyages to Constanța or Ukraine still cross high seas that are now listed. A voyage to a Romanian port can therefore face the new insurance scrutiny before the ship reaches the exempt coastal segment.
Key takeaways
- The 16 September circular places almost the entire Black Sea within the listed area, while Romanian and most other adjoining-state territorial waters remain exempt.
- More voyages may now face notification, underwriting review and contract-specific negotiation. The circular sets neither a standard premium nor a navigation restriction.
- Lost access would require operational evidence such as owner refusals, fewer port calls, route diversions or falling throughput. No such post-circular series is yet public.
What the notice changes
The Joint War Committee’s circular replaces a coordinate-defined zone bounded by points from the Ukraine-Romania border to the Russia-Georgia border. The new notice extends the designation across the sea and repeats that its application to an individual contract remains a matter for negotiation. Price, coverage and any additional premium remain contract-specific.
The circular gives underwriters a reason to review more voyages, but it does not stop a ship from calling at Constanța or a Ukrainian port. Depending on the policy, an owner may have to notify the insurer and negotiate an additional premium. Neil Roberts, the committee’s head of marine and aviation, said the reporting requirement now applies across the Black Sea. He added that voyages within the territorial waters of adjacent states do not require notification.
“The circular gives underwriters a reason to review more voyages, but it does not stop a ship from calling at Constanța or a Ukrainian port.”
This can still raise costs. Reuters reported that additional premiums can currently add hundreds of thousands of dollars to a seven-day voyage. The figure is a snapshot of prevailing market conditions. The circular leaves the actual price to contract negotiation, and rates were already rising as attacks on commercial vessels increased. Comparable quotations from before and after the change would be needed to separate its effect from the effect of those attacks.
Physical attacks remain the underlying risk
The wider listing followed more violence against merchant shipping during Russia’s war against Ukraine. Ukrainian officials said Russian fire struck the Golden Leo after it left Chornomorsk through a Ukrainian-controlled corridor towards Romania on 19 July. The vessel sank a week later and nine crew members were killed. A Reuters witness saw smoke rising from the ship after the strike. Moscow did not comment on the allegation.
On 17 September, a Ukrainian infrastructure official said a Russian drone hit a vessel heading to a Ukrainian port, killing its captain and injuring three crew members. These incidents explain the tighter scrutiny. Establishing any subsequent effect on traffic will require data on voyages and port activity. Russia remains the aggressor in the war, regardless of uncertainty that may surround the evidence for an individual maritime incident.
A separate Reuters report found that Caspian Pipeline Consortium oil exports rose by 22 percent in August after fewer tanker attacks. The report did not attribute those attacks. The episode offers a concrete example of owners and cargo interests responding when physical danger rises or falls. Its relevance is to shipping behaviour, not to the effect of every listed-area revision.
Access requires operational evidence
A genuine loss of shipping access would appear in operations. Relevant evidence would include owners refusing voyages, insurers excluding named ports or cargoes, fewer port calls, longer routes, sustained increases in comparable quotes, longer transit times or falling throughput after accounting for attacks and seasonal trade. No public post-circular series yet shows those effects for Ukrainian or Romanian ports.
The 16 September decision has expanded the insurance review applied to Black Sea voyages. Routes crossing listed high seas can now face notification and individual negotiation before reaching exempt Romanian waters, while voyages entering Ukrainian waters remain inside the listed area. Current evidence does not demonstrate lost access. That judgment should change if post-16 September data reveal persistent declines in port calls or throughput, documented owner refusals, route diversions, or premium increases that remain after the effect of attacks is separated.
