The Swiss government is open to revising its offer to the United States in response to planned heavy tariffs, Business Minister Guy Parmelin said, as experts warned the 39% import duties announced by President Donald Trump could trigger a recession in Switzerland.

A 39% tariff on Swiss goods is a blow for a country that hoped to reach an early trade deal with the Trump administration. The rate, due to take effect on Thursday, exceeds the 31% level floated in April.

39%? For Switzerland, this is a huge shock, and worse than the worst-case scenario – these are the highest tariffs in Europe. Globally, the fourth highest, behind only Syria, Laos, and Myanmar, (although if President Trump follows through on his 50% tariff threat then Brazil will jump to the top of the list).
