How a One-Year-Old US-EU Trade Deal Is Already Being Tested to Breaking Point

The US-EU trade framework was negotiated to provide stability. Here is why, less than a year in, it is already being stress-tested by the IEEPA ruling, NATO threats, and pharmaceutical tariff signals.

The EU-US Framework Agreement on Reciprocal, Fair, and Balanced Trade was described at its August 2025 announcement as the beginning of trade stability between the world's two largest economic blocs. Less than a year into provisional application, it is being tested by a series of developments that its negotiators did not fully anticipate.

Stress test one: the IEEPA ruling. The Supreme Court's 6-3 decision that IEEPA tariffs were unconstitutional removed the legal authority that underpinned the pressure that produced the deal. The EU-US framework was negotiated under the implicit threat of IEEPA tariff escalation; with that threat removed by judicial action, the deal's underlying power dynamic has shifted. The EU Commission's legal analysis team is assessing whether specific deal commitments that were premised on IEEPA authority have been altered by the ruling.

Stress test two: pharmaceutical tariff signals. The administration's signal that pharmaceutical tariffs of potentially 200 percent are coming under a separate review process directly threatens European pharmaceutical exports that the framework agreement's tariff ceiling was supposed to protect. EU pharmaceutical industry representatives have formally raised this in the trade dialogue mechanisms the framework established, calling it inconsistent with the deal's spirit if not its letter.

Stress test three: NATO withdrawal threat. Trump's 'absolutely considering' NATO exit statement, linked to European refusal to join the Iran campaign, has introduced security relationship deterioration into the commercial relationship context in ways that the framework agreement was not designed to manage. European governments whose trade and security relationships with the US are both under strain are navigating a situation where each dimension of the relationship affects the other.

Despite all three stress tests, the framework remains operative. The 15 percent tariff ceiling on most EU exports to the US is the operative structure. Neither side has formally triggered the consultation or dispute resolution mechanisms that the framework established. But the stress is real, and the framework's durability depends on whether the next twelve months produce additional complications or allow the commercial relationship to stabilise.
