What triggered the new USTR probe into Switzerland?

US authorities opened a Switzerland trade investigation after a legal defeat on earlier duties. Officials now seek a fresh record to support potential measures. The review cites the Swiss trade surplus and alleged barriers. It is an administrative step that could justify new actions if investigators find harm.

Which Swiss sectors are most exposed if tariffs return?

Machinery, precision instruments, chemicals, and watches have notable US exposure. Tariffs would raise delivered costs and weigh on margins. Firms with complex cross-border inputs may also face delays and compliance costs. Pharma has pricing power, but specific products could still see pressure depending on any final list.

How could this affect the Swiss franc and local equities?

Tariff headlines can boost CHF as a safe-haven, yet a stronger currency hurts exporters. Equities often react first through cyclicals tied to US demand, while defensives can be more resilient. Earnings uncertainty may widen credit spreads. The path depends on scope, timing, and whether exemptions or settlements emerge.

What can investors in Switzerland do now?

Audit US revenue shares, contract pass-through rights, and supply alternatives. Use FX hedges around earnings dates. Tilt toward balance sheets with low leverage and stable cash flows. Keep dry powder for volatility-driven entries. Track USTR notices, company guidance, and customs data to spot stress before it reaches earnings.
