Black Sea surpasses Hormuz as deadliest shipping lane

Attacks on 570 vessels in 2026 push Black Sea fatalities past Strait of Hormuz levels as NATO bolsters patrols.

A relentless surge of attacks over the past four days has cemented the Black Sea’s grim status, with seafarer deaths now exceeding those around the Strait of Hormuz, where 24 have been killed in 120 incidents this year. Maritime security firm Ambrey and the International Maritime Organization (IMO) confirmed the figures, which underscore the widening threat to commercial shipping beyond Ukraine’s territorial waters.

The attack capsized the ship, killing one seafarer, leaving three missing, and forcing the rescue of nine others. Romanian President Nicușor Dan directly blamed Russia, calling it
“another escalation of Moscow’s war against Ukraine.&quot.

Four days of escalation push fatalities past Hormuz: Black Sea

A Romanian navigational warning issued on Sunday confirmed the Khoryv remains partially submerged and drifting south of its original position, with vessels instructed to maintain a one-nautical-mile exclusion zone.

Russia’s defence ministry has claimed a series of strikes on port infrastructure and cargo vessels since Friday, though none have been independently verified. On Friday, Moscow said it targeted facilities at Vylkove on the Danube, including installations allegedly used for operating unmanned surface vessels, and struck a cargo ship bound for Odesa. Similar claims followed on Saturday, with Russia reporting attacks on Chornomorsk, including a workshop manufacturing unmanned vessels, and another cargo ship en route to Odesa.

The pattern continued on Sunday, with Russia announcing two more cargo vessel strikes, one overnight for Chornomorsk and another during the day for Odesa. Today, Moscow claimed yet another attack on a ship heading to Odesa, alongside strikes on cargo-handling infrastructure at three berthing terminals in Chornomorsk.

Ambrey recorded nine merchant vessels struck in Romanian and Bulgarian waters in October alone, including several sunk or badly damaged near NATO coastlines. The security firm cautioned that no merchant vessel can be assured of protection from drones operating near alliance territory, prompting NATO to deploy additional maritime patrol aircraft, surveillance equipment, and drones to monitor the region.

The commercial fallout is severe. War-risk insurance premiums for Black Sea voyages have soared to 15% of a vessel’s hull value, roughly double the rates for the Persian Gulf. The Joint War Committee has expanded its listed high-risk area to cover nearly the entire Black Sea, excluding only the territorial waters of Türkiye, Romania, Bulgaria, and Georgia.
