THE European Union has spent more than three years trying to strike a difficult balance: punish Russia without inflicting intolerable damage on itself. As negotiators haggle over the details of a 21st sanctions package, that familiar tension is once again on display.

When European Commission president Ursula von der Leyen unveiled the package in June, she promised measures that would further squeeze Moscow’s energy revenues. A month later, the final outcome looks increasingly likely to be another exercise in political compromise.

The latest dispute centres on the oil price cap. Brussels wants to freeze the EU’s current cap on Russian crude rather than allow it to rise above the price of Urals crude next week. Yet even this relatively modest measure has become entangled in national interests. Greece is pushing for a shorter freeze period and, in return, wants to preserve its ability to ship Russian LNG to non-EU destinations, a concession that would dilute earlier claims that Europe was closing off loopholes in the LNG trade.

This is hardly new. Every sanctions package is shaped by a process of horse trading that reflects the reality that member states do not share equal exposure to Russian energy flows or shipping’s quietly powerful lobbyists. The result is often a package that is politically achievable rather than strategically decisive.

More revealing, however, is what is happening beyond Brussels’ negotiating rooms.

France and the UK have increasingly turned to a more direct form of pressure by detaining sanctioned shadow fleet tankers that enter European waters without valid registration. The strategy has delivered visible results and generated favourable headlines. Officials point to the detention of vessels such as Smyrtos (IMO: 9389100) as evidence that targeting stateless ships can disrupt Russia’s maritime supply chain.

But sanctions rarely remain a one-sided contest.

Rather than eliminating the trade, the campaign appears to be accelerating its adaptation. Operators are seeking alternative registrations before entering European waters, swapping fraudulent flags for legal — if often poorly performing — registries in places such as Equatorial Guinea and Sierra Leone. Others are looking directly to Russia itself.

Moscow is now preparing measures that would make it easier for foreign-owned vessels to reflag under the Russian register, offering a new layer of protection for ships involved in sanctioned trades. At the same time, Russia has begun challenging European enforcement tactics at the International Maritime Organization, arguing that rapid deregistration campaigns create legal ambiguities that are then exploited to justify detentions under international law.

Whether those complaints have merit is almost beside the point. What matters is that every new enforcement measure is generating a countermeasure. Europe’s sanctions campaign is undoubtedly making life harder for Russia’s shadow fleet. But it is also reshaping it, driving operators towards new flags, new legal structures and new routes. As ever with sanctions, pressure creates adaptation. The question is whether Europe can keep pace with the consequences of its own success.
