Black Sea Becomes the New Global Chokepoint
July saw a dramatic surge in attacks on ships and ports, driving up freight and insurance costs and disrupting key trade routes.

A sharp rise in attacks on ships, ports, and export terminals in the Black Sea is disrupting global grain and oil supplies, turning this vital region into the latest strategic chokepoint hit by escalating conflicts. The Black Sea is a key route for grain, crude oil, and refined products, with its waters shared by Russia, Ukraine, Bulgaria, Georgia, Romania, and Turkey.
Russia, the world's largest wheat exporter, and Ukraine, also a major agricultural exporter, have intensified attacks on each other's agricultural export capacities and commercial vessels in recent weeks. Kyiv has also stepped up strikes on tankers involved in Russian oil trade. The effects of this escalation are already being felt in global markets.
"The consequences ... are already visible in global agricultural markets. We must not allow this dangerous spiral of escalation to continue," said UN official Kayoko Gotoh at a UN Security Council meeting last week.
The latest escalation adds another pressure point for commodity markets already facing disruptions on major shipping routes in the Middle East. Oil flows through the Strait of Hormuz have been disrupted by the US-Iran conflict, while a naval blockade declared by Yemen's Houthis on Saudi ports and ships has increased risks for navigation in the Red Sea.
According to data from Ukraine's Ministry of Infrastructure, Ukraine recorded 35 attacks on vessels in port and 22 at sea in July 2026, along with 67 strikes on port facilities. In comparison, vessels were attacked 14 times during the entire year of 2025. Russian shipping group FESCO announced this week that it has suspended new orders for deliveries across the Black Sea after one of its vessels was hit in a Ukrainian drone attack.
Russia, meanwhile, has intensified attacks on civilian vessels and port infrastructure around the southern Ukrainian hub of Odesa, through which more than 90% of Ukraine's agricultural exports pass. Both Russia and Ukraine claim to target only military-related objectives.
Agricultural products remain Ukraine's largest source of export revenue more than four years into the war. Kyiv is seeking alternative export routes, but Ukrainian Agriculture Minister Taras Vysotskyi said this week that they will not reach full capacity until the end of August and will only be able to carry about half of the volumes normally shipped through Black Sea ports.
Navigation in the Sea of Azov, which leads into the Black Sea, has been restricted since July 10, 2026, affecting operations at the major Russian grain port of Taman. Grain exports continue from Novorossiysk and Tuapse, but at a slower pace than before. Ukrainian attacks on tankers in July damaged several vessels and forced temporary suspensions of loading at Novorossiysk and at the Caspian Pipeline Consortium (CPC) terminal, the main export terminal for Kazakh oil.
"The CPC system is a critical export route for Kazakhstan, carrying approximately 80% of that country's crude oil exports, making any prolonged disruption a potential concern for regional supply flows," said a report from shipbroker BRS this week.
Growing security risks are also pushing up shipping costs. Average daily rates for crude oil tankers in the Black Sea have surged to over $300,000, up from just over $200,000 a week ago, according to market estimates. War risk insurance premiums for calling at Black Sea terminals have risen to as much as 2% of a vessel's value, up from around 1% two weeks ago, according to insurance industry sources. Even small increases translate into hundreds of thousands of dollars in additional costs per voyage.
British maritime security firm Ambrey has advised clients that vessels continuing to call at Black Sea ports should conduct comprehensive voyage threat assessments, and crews should remain at designated safe muster points during drone attacks.
"Killing innocent civilian seafarers is unacceptable; they cannot be 'collateral damage' for achieving military objectives, that is an immoral and very dangerous precedent," said Stephen Cotton, General Secretary of the International Transport Workers' Federation seafarers' union.
Niels Rasmussen, Chief Shipping Analyst at BIMCO, warns of broader implications: "If (Black Sea) volumes continue at the reduced levels seen over the past two weeks, global crude (oil) tanker volumes could fall by 3% in an already challenging market."
