Türkiye Restricts Black Sea Shipping Transit Following Surge in Vessel Attacks

Ankara is restricting commercial shipping transit into the Black Sea amid mounting alarms over a spike in maritime strikes by Russian and Ukrainian forces.

Türkiye's Directorate General of Coastal Safety is currently withholding or delaying transit permits through the Dardanelles Strait.

The administrative blockade primarily targets vessels bound for the critical Russian oil and agricultural export hub of Novorossiysk.

Sources familiar with the matter indicated that ships en route to Ukrainian ports face similar administrative hurdles, according to Bloomberg.

Maritime authorities have declined to publicly explain the sudden permit suspension.

Regional Security Deteriorates

The unannounced policy shift follows a rapid deterioration of maritime security in the region.

Recent drone strikes have heavily targeted commercial shipping lanes, prompting Ankara to demand enhanced protective measures.

The Turkish Foreign Ministry reported earlier this week that several citizens sustained injuries during drone strikes on two distinct Turkish-owned vessels.

The Nadezhda, a roll-on/roll-off cargo ship, was among the latest casualties in the contested waters.

“We reiterate our call to all relevant actors, especially the warring parties, to urgently implement concrete measures to ensure navigational safety in the Black Sea,” the Foreign Ministry stated.

Officials warned that further escalation risks severe consequences for global food security.

A separate Turkish oil tanker suffered a drone strike near the Caspian Pipeline Consortium terminal at Novorossiysk last month.

Persistent attacks have repeatedly forced the facility to suspend and resume loading operations over recent weeks.

Global Commodity Pressures

Transit bottlenecks at the Dardanelles risk compounding existing global supply chain disruptions. International oil markets are already strained by the war in Iran and diminished traffic through the Strait of Hormuz.

The escalating Black Sea theater is simultaneously threatening regional agricultural exports. Heightened security risks previously drove global wheat prices to a two-year peak in July.

Vessels destined for ports outside Russia and Ukraine remain unaffected by the new permit delays.

Tracking data confirmed ships sailing to Bulgaria, Romania, Georgia, and domestic Turkish ports navigated the Dardanelles unimpeded on Saturday.

The Montreux Mandate

The Bosphorus and Dardanelles straits form the sole maritime corridor connecting the Black Sea to the global ocean via the Aegean. Government data indicates more than 40,000 vessels transited the Bosphorus in 2025.

Under a 1936 international convention, Türkiye is obligated to guarantee civilian passage through the straits. However, the treaty grants Ankara sovereign authority to regulate traffic for immediate navigational safety.

The NATO member has strategically preserved diplomatic relations with both Moscow and Kyiv throughout the ongoing war. Yet, regional hostilities have forced previous maritime interventions.

In 2022, Turkish authorities mandated supplementary insurance documentation from shipping operators.

That directive followed European Union sanctions that stripped maritime coverage from specific regional cargoes.
