Executive Summary

On February 20, 2026, the US Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA) does not provide the President with a basis for comprehensive additional tariffs. The US government responded swiftly and introduced new additional tariffs based on Section 122 of the US Trade Act, which came into effect on February 24. The Federal Council was informed and is continuing its negotiations with the United States to secure stable framework conditions for the Swiss economy.

The US Supreme Court blocked the additional tariffs imposed under the IEEPA, which had been in effect since April 2025. The US government circumvented the ruling through new additional tariffs under Section 122 of the US Trade Act, which represent a 150-day transition period. For Switzerland, securing stable market conditions remains the central negotiating objective; the USA signaled respect for existing trade agreements.

Detailed Summary

The court found that the IEEPA – an emergency law for economic crises – does not grant the President the authority to impose general tariffs. This decision invalidated the legal basis for the comprehensive additional tariffs that had been in effect since April 2, 2025. The US government subsequently announced new tariff measures immediately and implemented them on February 24.

The new additional tariffs under Section 122 replace the previous country-specific tariffs for 150 days and are applied in addition to most-favored-nation tariffs. The US government announced it would prepare further trade policy measures on alternative legal grounds. At the same time, it emphasized respect for existing trade agreements – including Swiss agreements. The Federal Council is analyzing the impacts and will consult on further steps at an upcoming session.

Key Points

  • The IEEPA legal framework was ruled inadmissible by the Supreme Court for additional tariffs
  • The USA responded with new tariffs under Section 122, which apply for 150 days
  • Switzerland retains its negotiating mandate to secure stable market conditions
  • The US government signaled respect for existing trade treaties

Critical Questions

  1. Evidence: What are the concrete impacts of the new Section 122 tariffs on Swiss exports, and are estimates of trade volume losses already available?

  2. Conflicts of Interest: Which economic sectors in Switzerland are particularly affected by the new tariffs, and are there conflicts of interest between different industries in the negotiations?

  3. Causality: To what extent does the US announcement to respect existing trade agreements guarantee that Switzerland will not be burdened by the new tariffs – or could Switzerland still be affected?

  4. Feasibility: What concrete negotiating leverage does Switzerland have to achieve its objectives in the coming 150 days before the new tariffs are potentially extended?

  5. Alternatives: Has the Federal Council conducted scenario analyses in case the USA introduces further tariff measures on yet other legal grounds?

  6. Transparency: When will the Federal Council inform the public about concrete negotiation results and possible protective measures for the Swiss economy?
