The EU is pressing the US to urgently restore tariff rates agreed under last year's Turnberry trade deal, with EU Trade Chief meeting US counterparts as Trump's new 25% auto tariffs add fresh friction to transatlantic commerce. Meanwhile, a $166 billion tariff-refund wave is reshaping corporate America following the Supreme Court's invalidation of IEEPA-based tariffs, raising questions about who truly benefits from the ongoing trade disruption.

1. EU Presses US to Reinstate Turnberry Deal Tariffs Amid Escalating Tensions
The European Union's trade chief formally urged the United States on Tuesday, May 5, to swiftly restore the tariff levels agreed under last year's EU-US Turnberry trade deal. The European Commission issued a pointed statement warning that if Washington takes actions inconsistent with the agreement, Brussels "reserves the right to consider all options." The move comes just days before the one-year anniversary of the deal and signals mounting frustration in European capitals.

The Turnberry deal remains under active negotiation between EU governments and lawmakers before it can fully take effect on the EU side, making Washington's compliance all the more critical.
Market implications: European exporters — especially in automotive and luxury sectors — face continued uncertainty. The Bloomberg newsletter noted that "more than a year after Liberation Day, there's a real chance the US-EU trade conflict is back."
2. Supreme Court Ruling Triggers $166 Billion Tariff Refund Wave
A significant downstream consequence of the US Supreme Court's decision to invalidate IEEPA-based tariffs is now coming into focus: approximately $166 billion in potential tariff refunds could flow back to American companies — much of it going directly into executive bonus pools and corporate boardrooms. The court's ruling struck down a large chunk of the "Liberation Day" tariffs President Trump had previously imposed on most of the world's imports.
The refund wave has not only opened the door to corporate windfalls but also forced the Trump administration to impose replacement tariffs, which themselves are now under review by a three-judge trade court panel that has questioned their legal basis.
Business implications: Companies in import-heavy sectors should be actively reviewing their customs filings and legal exposure. The replacement tariffs remain in legal limbo.
3. UK Parliament Briefs MPs on US Tariff Impact Amid Ongoing Deal Negotiations
The UK House of Commons Library updated its research briefing on US trade tariffs on May 6, noting that the US has imposed tariffs on most UK goods imported into the US and examining how the current UK-US deal framework will mitigate that exposure. The briefing is aimed at MPs navigating what has become one of the most complex bilateral trade relationships in recent British history.

Market implications: UK exporters — particularly in steel, aluminum, automotive, and aerospace — are watching closely. The UK-US deal framework remains the primary mechanism for reducing the tariff burden, but final terms are still not locked in.

United States (IEEPA tariffs) | Most imports globally | Voided / Replacement tariffs under legal challenge Following the Supreme Court's invalidation of broad IEEPA-based tariffs, the Trump administration imposed replacement tariffs, which a three-judge US trade court panel is now scrutinizing for legality — specifically whether a large trade deficit constitutes sufficient grounds for sweeping import duties.

The Turnberry Anniversary: How the EU-US Trade Deal Became a Flashpoint
As the one-year anniversary of the EU-US Turnberry trade deal approaches, the agreement — once celebrated as a détente in transatlantic trade hostilities — is under serious strain. EU Trade Commissioner met US counterparts this week to demand that Washington restore the tariff framework both sides had agreed upon.

The Commission explicitly reserved the right to pursue countermeasures if the US continues to act inconsistently with deal terms — a significant escalation in diplomatic language. Bloomberg described the situation as the US-EU trade conflict "resurfaces yet again," noting that the risk of a full re-escalation is no longer theoretical.
For businesses operating across the Atlantic, the key risk is a return to the tariff volatility of the Liberation Day era. European automakers are already facing Trump's new 25% tariffs imposed just days ago. French wine producers, Italian luxury goods manufacturers, and German industrial firms are watching the Brussels-Washington dynamic closely.
Why it matters globally: The EU-US trade relationship represents the world's largest bilateral trade flow by value. Any sustained deterioration directly affects global supply chains, currency markets, and the viability of multilateral trade norms.
What to Watch Next Week
-
EU-US Trade Talks (Ongoing) — Week of May 11: Watch for whether EU and US trade officials reach any agreement on restoring the Turnberry deal tariff framework. The Commission has explicitly threatened retaliation if the US does not comply. Failure to reach a deal could trigger formal EU countermeasures.
-
US Trade Court Ruling on Replacement Tariffs (Pending): The three-judge trade court panel is deliberating on the legality of the Trump administration's replacement tariffs imposed after the Supreme Court voided the IEEPA-based tariffs. A ruling could invalidate another round of duties — and potentially trigger further refund flows.
-
UK-US Trade Deal Negotiations (Ongoing): With the House of Commons Library flagging continued uncertainty around US tariffs on UK goods, any movement in UK-US bilateral negotiations will be closely watched by UK exporters in automotive, steel, and aerospace sectors.
-
Turnberry Deal Anniversary (Mid-May): The approaching one-year mark of the EU-US Turnberry deal is a symbolic and potentially substantive deadline. Both sides face pressure to demonstrate the deal has durable value — or acknowledge it has broken down.
