Black Sea attacks reach NATO’s doorstep as Europe widens Russia sanctions

Second ship sunk off Bulgaria in a week. Western Black Sea cargo will cost more. A drone-hit cargo ship, HS Dignity, sank off Bulgaria overnight with 11 crew missing, Reuters reported on 13 October. It was heading for Braila, Romania. A second ship, Chelsea-3, was hit by three drones. A week earlier, another drone attack in Bulgaria’s economic zone left 10 sailors lost. Our view: the “safe” western corridor to Romania is no longer safe. In September, London insurers widened their high-risk zone to the whole Black Sea. Romanian and Bulgarian coastal waters were left out. We expect underwriters to start charging extra for Constanta and Danube calls by end of November.

The western Black Sea has lost its safe-lane status, and Romania’s trade will pay for it

A cargo ship bound for Romania sank off Bulgaria’s coast overnight after a drone attack, Reuters reported from Sofia on 13 October. Eleven sailors are missing. Five were rescued.

The ship was HS Dignity, flagged in Guinea-Bissau. It went down near Krapets, a village close to the Romanian border. According to Reuters, it was part-loaded and sailing to Braila, a Romanian port on the Danube, after calling at Mostaganem in Algeria.

The same night, a second ship was hit. The Malta-flagged Chelsea-3 took three drones. All 15 crew were rescued and none were seriously hurt.

This was not a one-off. About a week earlier, Reuters says, “nine Syrian sailors and one Egyptian were lost at sea from a ship that sank when hit by drones” inside Bulgaria’s exclusive economic zone. An exclusive economic zone is the stretch of sea, out to 200 nautical miles, where a country controls fishing and seabed resources. It is not the same as its territorial waters, which run 12 nautical miles from shore.

Our view is simple. For most of this war, the western Black Sea, the side that serves Romania, Bulgaria and the Danube, was treated as the calmer route. That is no longer true. Two sinkings in a week, both close to EU and NATO waters, mean higher costs and fewer options for anyone moving cargo into south-east Europe.

Two sinkings in a week, both next to NATO

The first ship was the Alfa Watan, a Togo-flagged general cargo ship. Insurance Business reported on 6 October that it sank after critical structural damage about 128 km off Bulgaria near Byala, inside Bulgaria’s exclusive economic zone. A second vessel in that attack, the Palau-flagged Able, was carrying wheat and caught fire. Its 18 crew were taken off by a Bulgarian ferry. Two were seriously injured and flown to hospital in Varna.

Then came this week’s attacks, which happened closer to shore and closer to Romania.

Bulgaria’s response was sharp. “This is absolutely unacceptable — another attack in the immediate vicinity of Bulgarian territorial waters,” Prime Minister Rumen Radev said in a televised address, according to Reuters.

Bulgaria summoned Russia’s ambassador, Eleonora Mitrofanova. Reuters reports she said Russia’s Defence Ministry had given her no information, and she did not rule out a provocation by a third party. Bulgaria did not directly blame Russia. But Radev said the outcome of the attacks “benefits the Russian Federation.” Moscow had not commented when Reuters published.

The EU and NATO both weighed in. “The Black Sea has become another front of escalation of the Russian war in Ukraine,” European Commission President Ursula von der Leyen said on X. Radev asked von der Leyen and NATO Secretary General Mark Rutte for help with sea and air surveillance. Rutte said NATO would keep adjusting its military presence on its eastern flank “as needed.”

Why the insurance map matters

To see why this hits freight costs, look at the insurance map.

War-risk cover is separate from normal marine insurance. In London, the Joint War Committee, a group of Lloyd’s and company underwriters, publishes a list of “listed areas”. These are waters where insurers can ask for notice before a voyage and charge an extra premium on top of the normal policy.

In mid-September, the committee widened that list. “This week, the JWC has expanded the Black Sea reporting requirements to the whole of the Black Sea area,” Neil Roberts, the committee’s secretary and head of marine and aviation at the Lloyd’s Market Association, told Reuters, as carried by gCaptain on 18 September. “The coastal waters of Russia and Ukraine were already listed,” he added.

There was a gap. “However, voyages within the territorial waters of adjacent countries still do not require notification,” Roberts said. Ukrainian trade outlet UkrAgroConsult reported that the listed areas would exclude “the territorial waters of Turkey, Georgia, Bulgaria and Romania”.

In plain terms, a ship that hugs the Bulgarian and Romanian coast on its way to Constanta or the Danube could still avoid the extra paperwork, and often the extra premium.

This week’s sinking happened, in Radev’s words, “in the immediate vicinity of Bulgarian territorial waters”. That is the exact edge of the exemption. Insurance Business had already flagged the risk after the first sinking, writing that coastal exemptions “may come under closer scrutiny” and that hull war and cargo war underwriters, along with P&I clubs, “are likely to face pressure to reprice western Black Sea exposure”. P&I is protection and indemnity insurance, which covers a shipowner’s liability to crew, cargo owners and third parties.

What happened last time

There is a recent pattern to learn from. In January this year, after drone attacks on oil tankers, Marine Insight reported, citing Reuters and five industry sources, that war-risk costs for ships calling at Black Sea ports had climbed to around 1% of a vessel’s value. That was up from roughly 0.6% to 0.8% in late December.

One per cent sounds small. It is not. On a ship valued at $20 million, 1% is $200,000 for a single call. Reuters reported in September, as carried by gCaptain, that war-risk premiums were already adding hundreds of thousands of dollars to every seven-day voyage in the listed waters.

The lesson from January is that underwriters move fast once attacks cluster. They reprice within days, not months. A broker at McGill and Partners told Marine Insight at the time that rates were changing daily and could go above 1%, depending on the ship’s value, who owns it and where it is calling.

So far, the published repricing has centred on Russian and Ukrainian waters. Our view is that this week moves the western coast into the same conversation.

Sanctions are tightening at the same time

The attacks came as Europe stepped up pressure on Russian shipping from another direction.

On 12 October, the EU published and put into force its largest expansion of the Russia sanctions list since the war began. It adds 826 companies and 743 executives, roughly 1,600 listings. “This is the single largest expansion of our sanctions list since Russia started its war,” EU foreign policy chief Kaja Kallas said, as reported by gCaptain.

The list includes some of Russia’s biggest shipyards: Admiralty Shipyards, Sevmash, Amur Shipbuilding Plant, Severnaya Verf, Vyborg Shipyard and the Zvezdochka and Dalzavod repair centres, among others. gCaptain notes the listings freeze assets and bar EU persons and firms from making funds available to these entities. They are not a blanket ban on Russian-built ships. gCaptain reports the regulation came into force on the day it was published. It mentions no grace period.

Enforcement at sea is also reaching further. On 13 October, Reuters reported that French forces boarded the tanker DF Peak by helicopter about 450 nautical miles south of Réunion in the Indian Ocean. The ship, formerly named Kaliningrad, has been under US, UK and EU sanctions since 2024. “We had doubts regarding the flag under which this vessel was sailing, so we carried out an inspection,” French army spokesperson Col. Xavier Rival said. “France is determined to combat the shadow fleet, wherever it may be in the world,” President Emmanuel Macron said. Reuters says it is at least the fifth Russia-linked tanker France has seized since 2024. Russia’s embassy called it “piracy”.

What this means for forwarders

Start with routing. Romania’s Danube ports, such as Braila, and the sea port of Constanta are the main entry points for south-east Europe from the Black Sea. Reuters also notes Ukraine now leans more on river ports on the Danube. That means the same narrow stretch of water carries Romanian imports, Ukrainian exports and a lot of grain. Ukraine and Russia are both among the world’s largest grain exporters.

Next, cost. If underwriters close the coastal gap, every call into a western Black Sea port could carry an extra war-risk premium. Shipowners pass those costs on. For breakbulk, steel, project cargo and grain, that usually comes as a line on the freight invoice. For containers, it usually arrives as a war-risk or emergency surcharge from the carrier.

Then, capacity. Some owners will simply refuse western Black Sea calls, or demand more money to make them. Fewer willing ships mean higher rates and longer waits, especially for smaller general cargo vessels serving the Danube.

Finally, compliance. The EU list grew by about 1,600 names overnight with no grace period. Any screening tool that has not pulled the 12 October update is out of date. That matters for anyone handling Russia-adjacent trade, ship repair, spare parts or vessels linked to the named yards.

Practical steps for this week: - Add a war-risk clause to Constanta and Danube quotes so you can pass on new charges. - Ask carriers and charterers now whether they plan surcharges for western Black Sea calls. - Warn customers that transit times into Romania and Bulgaria may stretch. - Refresh denied-party screening data against the 12 October EU list. - Check where cargo insurance excludes listed war areas, and whether the policy follows any change to the listing.

Our call

We expect the Joint War Committee or the London underwriting market to tighten cover for the western Black Sea coast by end of November 2026. That could mean narrowing the territorial-waters exemption, or underwriters quoting extra premiums for Romanian and Bulgarian calls even without a formal change.

We also expect at least one major container line to announce a war-risk or emergency surcharge on Constanta bookings before the end of the fourth quarter. Forwarders who build that cost into quotes now will avoid eating it later.
