Background
A founding NATO member since 1949, Denmark hosts US forces and F-35 squadrons and has been among the more hawkish EU states on Russia sanctions. It participates in the Joint Expeditionary Force, was represented at the Helsinki summit, and has already detained shadow fleet vessels in its waters. Sweden's seizure of the cargo ship Caffa near Trelleborg in March showed coordinated Baltic enforcement is operationally feasible.
Denmark controls the Danish Straits (Oresund, Great Belt and Little Belt), the only maritime route connecting the Baltic Sea to the North Sea without passing through the English Channel. After Britain announced at the JEF Helsinki summit on 26 March 2026 that the Royal Navy would interdict sanctioned shadow fleet vessels in Channel waters, the Danish Straits became the sole alternative Baltic exit for 600+ sanctioned tankers. Whether Copenhagen follows London's lead is now the pivotal question in the economic war against Russia's oil revenue.
If Denmark closes the straits to sanctioned tankers, Russia's Baltic fleet would face a genuine maritime blockade, with no short northern European passage remaining. The EU's parallel shift towards targeting shadow fleet operators and registries gives Copenhagen both legal cover and political pressure to act.
