In a landmark ruling, the US Supreme Court has declared Donald Trump’s global tariffs illegal, prompting swift responses from both the UK and the European Union as they assess the implications. Business leaders on both sides of the Atlantic are holding their breath, hoping for clarity and stability in what has been a turbulent trade landscape.

UK Government Collaborates with US

A spokesperson from Downing Street confirmed that the UK is actively engaging with the US administration to understand the ramifications of the court’s decision. The government remains optimistic, expecting that the UK’s privileged trading status with the US will persist despite the ruling.

Historically, the UK was the first nation to reach a tariff agreement with the US, which imposes a 10% tariff on imports from Britain—significantly lower than the EU’s blanket 15% rate. This unique position is vital for ongoing trade relations, and officials are keen to maintain this advantage.

EU’s Response and Future Tariff Discussions

The European Union is also taking stock of the Supreme Court’s decision. A representative stated that they are closely examining the ruling while continuing their efforts to negotiate reduced tariffs on American exports. Last July, the EU and the Trump administration agreed on the 15% tariff rate, but challenges remain, particularly with the 50% tariffs still placed on steel imports.

EU's Response and Future Tariff Discussions

“We remain in close contact with the US administration as we seek clarity on the steps they intend to take in response to this ruling,” the EU spokesperson noted. They emphasised the importance of a predictable trading environment, calling for ongoing advocacy for lower tariffs.

Business Community’s Concerns

The ruling opens the door for businesses affected by the tariffs to seek refunds from the US government, although the process for doing so is yet to be defined. Experts warn that while some tariffs may remain, the White House could pivot to imposing broader product-based tariffs, particularly on sectors like agriculture and technology.

John Denton, Secretary General of the International Chambers of Commerce, highlighted the uncertainty that still looms over businesses. “Many companies will welcome the prospect of refunds, but the complexities of US import procedures mean navigating this will not be straightforward,” he said.

William Bain, head of trade policy at the British Chambers of Commerce, echoed these sentiments, stressing that although the ruling clarifies the use of executive powers regarding tariffs, it does little to dispel the confusion surrounding future trade policies. He pointed out that Trump could still invoke the 1974 Trade Act to impose even higher tariffs.

Market Reactions

Following the Supreme Court’s announcement, the UK’s FTSE 100 index surged to a new intraday high, closing up 0.56%. Exporters experienced notable gains, with Diageo—known for its whisky and tequila brands—jumping by 3.9%, and luxury brand Burberry rising by 3.3%. European car manufacturers also saw their stocks climb, suggesting a positive market sentiment in response to the ruling.

Market Reactions

However, the US bond market reacted differently, with prices falling and borrowing costs rising as investors anticipated a potential loss of tariff income and the prospect of refunds for US companies.

Why it Matters

The Supreme Court’s decision not only shakes up the existing tariff framework but also highlights the fragile nature of international trade relationships. For the UK and EU, this is a pivotal moment that could reshape their economic futures, bringing both opportunities and challenges. As businesses navigate this new reality, the emphasis on stable, predictable trade agreements has never been more critical. The path ahead is uncertain, but the impacts of this ruling will reverberate across the global economy for years to come.
