The global shipping lanes have become a battlefield. In the last 48 hours, Russian missiles have targeted at least two cargo vessels in the Black Sea, sending a stark warning to maritime trade. One strike landed within 200 metres of a Maltese-flagged bulk carrier, the *MV Prosperity*, as it sailed near the Bosphorus. A second salvo struck a grain freighter, the *SS Harvester*, carrying 30,000 tonnes of Ukrainian wheat to Egypt. No deaths have been confirmed, but the message is clear: no vessel is safe.
This is not a war of tanks and trenches alone. It is a war on the price of bread. The Black Sea corridor is the artery for Ukrainian grain, sunflower oil, and maize. Before the invasion, Ukraine supplied 10% of the world's wheat. Now, every missile that lands near a freighter sends insurance premiums soaring. The cost of shipping grain has doubled in the past month. When shipping costs rise, the price of a loaf of bread rises in Cairo, in Nairobi, in Manchester.
For the workers on these vessels, this is a daily terror. Seafarers from the Philippines, India, and Ukraine themselves are caught between their duty to deliver food and the calculus of the Kremlin. “We are not soldiers,” one captain told me from a port in Romania. “We carry food. Why are we targets?” His voice crackled over a satellite phone. He wished not to be named for fear of reprisals. Behind him, I could hear the low hum of cargo cranes. The port is working overtime. Every grain of wheat that leaves Ukraine is a victory for the global supply chain.
But the Kremlin sees it differently. By striking near civilian vessels, Moscow aims to weaponise hunger. It is a strategy of economic attrition. If ships cannot sail, insurance companies will not underwrite war risk. If insurance is unavailable, shippers turn back. The export of Ukrainian grain, already down 40% from pre-war levels, could grind to a standstill. The UN-brokered Black Sea Grain Initiative, already fragile, is now on life support.
For the unionised dockworkers in Hull and Hamburg, this means less work. For the families in Gaza, where wheat imports are already choked by blockade, it means even higher prices. For the workers in the bakeries of London, it means bread that costs a pound more than it did a year ago. The economics of the kitchen table are being rewritten by missiles fired from warships.
NATO has condemned the attacks. The EU has pledged to extend its “solidarity lanes” – overland routes through Poland and Romania. But these routes cannot replace the sea. The trains and trucks are bottlenecks. The cost of land transport is three times that of maritime. The result is a two-tier system: rich nations can outbid the poor for what grain reaches port.
Ukraine has responded by expanding its own naval drone programme, sinking Russian patrol boats in the Black Sea. But the balance of power remains tilted. The world’s largest grain exporter is also one of the world’s largest naval powers. Russia has blockaded the Sea of Azov and parts of the Black Sea with mines and missiles. The cargo vessels are caught in the middle.
For the labour movement, the situation is a call to action. The International Transport Workers’ Federation has called for a safe corridor for seafarers. But what can unions do when the threat is a hypersonic missile? They can strike. They can refuse to sail into war zones. But that would cut off Ukraine’s last lifeline. It is an impossible choice: endanger workers or starve the world.
Today, the *SS Harvester* docks in Constanta. The crew will not sleep tonight. Tomorrow, the wheat will be loaded onto trucks, bound for the Horn of Africa. There, a mother will pay double what she paid last year for a bag of flour. She will not know the name of the ship or the men who risked their lives to bring it. But she will know the taste of a world where trade routes are no longer safe. And that is the real cost of this escalation.
