Global leaders and businesses are facing increased uncertainty following recent shifts in U.S. tariff policies. The U.S. Supreme Court's decision to void certain tariffs, specifically those impacting trade with Mexico, China, and Canada, has prompted urgent discussions among nations. However, ongoing disputes over tariffs on goods like vehicles, steel, and aluminum continue to create a complex trade environment.
The core issue is the unpredictability of U.S. trade policy and its broad impact on international commerce.
