The Treasury Secretary expects tariff rates struck down by the Supreme Court to return within the next five months, following ongoing trade investigations. The White House plans to reconstruct President Trump's tariff regime after a Supreme Court decision nullified previous levies. Treasury Secretary Scott Bessent announced a likely increase in a temporary global tariff to 15% this week, initially set at 10% after the court's ruling. This tariff will expire after 150 days unless extended by Congress. Concurrently, the Trump administration is expediting Section 301 investigations, potentially leading to additional duties, with completion expected within five months. These investigations have previously resulted in tariffs on imports from China and Nicaragua. The administration aims to recreate much of Trump's previous tariff regime using this mechanism. While the White House builds its case for new tariffs, there is uncertainty about the impact on trade agreements made in response to Trump's tariffs. Some countries, like the European Union, have paused efforts to implement trade agreements pending clarity on U.S. plans. Germany's Chancellor Friedrich Merz expressed support for a deal but not if terms change due to new tariffs. The situation raises questions about the future of transatlantic trade and investment agreements.
