Swiss President Karin Keller-Sutter has expressed doubts about the success of a US-Swiss trade deal aimed at reducing tariffs by the end of 2025. The deal's progress is uncertain due to the imposition of 39% tariffs on Swiss exports by US President Donald Trump in August 2025. In response, Switzerland has made investment commitments and implemented deficit-reduction measures to negotiate more favorable terms. The US is a significant market for Switzerland, accounting for 17% of its exports, with the pharmaceutical and medical technology sectors particularly vulnerable to potential levies of up to 100%.
