Turkey has called on Russia and Ukraine to agree to a moratorium on attacks on ships and maritime-related facilities in the Black Sea amid a sharp increase in attacks on the commercial fleet.
Turkish Foreign Minister Hakan Fidan stated on August 8 that Ankara is proposing that the parties establish a special mechanism to halt mutual attacks in the Black Sea.
“We have called on both sides to establish a mechanism for declaring a moratorium,” Fidan said in an interview with the Turkish state news agency Anadolu. According to him, Ukraine had previously put forward a similar proposal, after which Turkey conveyed it to the Russian side and is now awaiting Moscow’s response.
The Turkish foreign minister noted that the war has effectively spread to the entire Black Sea. While the attacks initially targeted mainly military ports and warships, commercial vessels are now increasingly coming under fire.
Ankara is particularly concerned about attacks on vessels linked to Turkey—those flying the Turkish flag, owned by Turkish companies, or carrying Turkish crew members.
According to Fidan, Russia and Ukraine are also attacking logistics facilities of strategic importance to the opposing side, and the further escalation of such actions is becoming “extremely dangerous.”
Ankara’s statement came after a sharp deterioration in the security situation for commercial shipping.
According to data from Ukraine’s Ministry of Community and Territorial Development, as cited by Reuters, in July alone, Ukraine recorded 35 attacks on ships in ports, 22 attacks on ships at sea, and 67 strikes on port infrastructure.
By comparison, Reuters counted 14 attacks on ships in the Ukrainian sector of the Black Sea throughout all of 2025. At the same time, Ukraine has intensified its strikes on tankers linked to the Russian oil trade. Both Moscow and Kyiv claim that their targets are facilities associated with military activities.
The escalation is already affecting global trade in grain and oil. More than 90% of the country’s agricultural exports pass through Ukrainian Black Sea ports, while the Russian ports of Novorossiysk and Tuapse remain major export hubs for grain and petroleum products.
The cost of war risk insurance for ships calling at Black Sea ports has risen to approximately 2% of a ship’s value, up from about 1% two weeks earlier, while the cost of chartering oil tankers on certain routes has exceeded $300,000 per day.
Amid rising risks, reports emerged that Turkey had begun restricting the passage of certain commercial vessels into the Black Sea. However, on August 9, two Turkish officials told Reuters that traffic through the Bosphorus and the Dardanelles was proceeding as usual. Ankara has indeed implemented temporary additional security measures, but these do not mean that the straits are closed to commercial shipping.
Passage is governed by the 1936 Montreux Convention, which grants Turkey control over the Bosphorus and the Dardanelles and special powers regarding military vessels, while ensuring freedom of passage for civilian vessels.
For Ankara, the security of the Black Sea is of fundamental economic importance. Large volumes of Russian and Ukrainian agricultural products, oil, and petroleum products pass through this region, and Turkish shipowners are actively engaged in these routes.
Since the start of the full-scale war, Turkey has maintained contacts with both Kyiv and Moscow and has sought to play the role of mediator. Ankara has not joined Western sanctions against Russia, yet it continues to cooperate with Ukraine and has repeatedly acted as a mediator on issues related to Black Sea shipping.
