Maritime trade tilts toward coercion

Maritime trade is supposed to be the plumbing of globalization. Containers move, tankers sail, ports load and unload, and most companies barely think about the route. But that old assumption is breaking. Over the past year — and especially in 2026 — governments have started using ships, ports, and sea lanes less like neutral infrastructure and more like pressure points. That matters because most world trade still moves by sea. Once states start treating maritime access as leverage, the cost of moving goods stops being just fuel, vessels, and labor. It becomes political risk. ### What changed? Three things stacked on top of each other. The U.S. moved ahead with Section 301 action aimed at China’s maritime dominance, including phased port service fees on China-linked and many Chinese-built ships. The EU adopted a 20th Russia sanctions package that creates the legal basis for a future maritime services ban on Russian oil trades. And in the Gulf, disruption around the Strait of Hormuz showed how quickly a chokepoint can become a live instrument of coercion rather than just a vulnerability.

A port fee, denial of service, insurance restriction, or sanctions screening rule hits the shipment at the point of movement. The U.S. measures are a good example — they ta(whitecase.com)ere a ship was built part of trade policy. (whitecase.com) ### Why is Hormuz the clearest warning? Because it showed how fast traffic can collapse when states signal that transit is no longer commercially safe. UNCTAD’s March update described the Strait of Hormuz as carrying about a quarter of global seaborne oil trade, plus major LNG and fertilizer volumes. It also showed daily ship (whitecase.com)— it is maritime pressure with global spillovers. (unctad.org) ### Is this only about oil? No — oil is just the fastest way the shock shows up. The same routes carry petrochemicals, fertilizers, grains, metals, and containerized intermediate goods. UNCTAD’s broader shipping reviews make the point pretty bluntly: chokepoint disruptions in the Red Sea, Suez, Panama, and Black Sea have already stretched ro(unctad.org)tested, electronics and agriculture feel it too. (unctad.org) ### So is this sanctions creep? Basically, yes. Sanctions used to focus more narrowly on named cargoes, banks, or companies. Now the maritime sector itself is becoming the enforcement terrain. Legal and compliance specialists are describing shipping as a front line for sanctions policy, with screening expanding from counterparties to vessel histories, AIS behavior, flag changes(unctad.org)— it is part of the target set. (hklaw.com) ### What does that do to business decisions? It raises the “maybe don’t use that route” premium. Companies now have to ask whether a voyage is technically possible, legally clean, insurable, and politically durable. The result is more diversification, more inventory buffers, more friend-shoring, and more willingness to pay for redundant (hklaw.com)point — trade is continuing, just through a thicker layer of friction. (portwatch.imf.org) ### Is this temporary? Probably not. The pattern now spans sanctions, industrial policy, and military pressure. The U.S. is using port access to counter China’s shipbuilding position. Europe is building maritime sanctions tools into its Russia playbook. Regional conflicts are turning chokepoints into bargaining chips. Those are different theaters, but they all push in the same direction — sea lanes are becoming governed space, not neutral space. (whitecase.com) ### What’s the bottom line? The old model said maritime trade was global by default and political only in emergencies. The new model is the reverse. Trade still flows, but the route, the ship, the insurer, the port, and the flag all carry strategic meaning now. That does not end globalization. But it does make coercion part of the freight rate.
