The head of Switzerland’s State Secretariat for Economic Affairs (SECO) said on Sunday that the country should be ready for the possibility that US tariffs could stay in effect indefinitely, even after last week’s US Supreme Court decision.

Switzerland was among the nations targeted when President Donald Trump imposed sweeping tariffs on global trading partners last year. It initially faced the highest tariff rate in Europe before the rate was later reduced.

Last week, the US Supreme Court invalidated Trump’s tariff program, after which he responded by announcing a blanket 15% tariff.

Helene Budliger Artieda of State Secretariat for Economic Affairs, the agency that handled technical tariff negotiations with the United States, told the Swiss newspaper SonntagsBlick that she anticipated the duties would remain in place.

“I suspect we will have to come to terms with US tariffs,” stated Budliger Artieda. She noted that the US government had suggested other legal options to preserve the tariffs, including using national security grounds or referencing unfair trade practices.

Swiss officials are evaluating the potential effects of Trump’s announcement of a 15% global tariff. Budliger Artieda stated that the total level of tariffs applied to Swiss exports is expected to stay largely the same, Reuters reports.

“It is clear that the US administration remains committed to its trade policy goals: reducing the US trade deficit, achieving greater reciprocity in international trade, and bringing production back to the United States.”

Bern and Washington reached a framework agreement in November to prevent a full-scale trade conflict. Under the arrangement, tariffs on Swiss exports to the United States were lowered from 39% to 15%, bringing them in line with the rate applied to European Union exporters.

In exchange, Swiss companies pledged to invest a total of $200 billion in the United States by the end of 2028.

At the time, both parties committed to completing the agreement by the end of March, and discussions are still underway, Budliger Artieda said.

She added that SECO has been in contact with US trade officials following the court’s decision.
