A year on: Four ways Trump's tariffs have changed the global economy

President Trump's tariffs have pushed US import duties to their highest levels in decades, reshaping trade patterns across the global economy a year into his second term. The Trump administration's tariff strategy has affected multiple sectors and trading partners, altering costs for consumers and businesses while influencing supply chains and investment decisions worldwide. The shift represents a significant departure from the post-World War II free-trade framework that has underpinned international commerce for generations. Major economies and US trading partners have responded with their own retaliatory measures, creating cascading effects on exports, pricing, and economic growth rates globally. The tariff regime continues to be a defining feature of Trump administration economic policy, with ongoing impacts on inflation, corporate profitability, and geopolitical trade relationships.
