Nations around the world have threatened to escalate trade tensions with the United States after President Donald Trump unveiled sweeping new tariffs, stoking fears of significant price hikes in the world’s largest consumer economy.
Announced on Wednesday, the tariffs triggered a global sell-off in financial markets on Thursday and drew sharp criticism from international leaders. Many viewed the move as the end of a decades-long era of global trade liberalization.
There was confusion from within the White House, as officials gave mixed signals about whether the tariffs were a long-term policy or a strategic bargaining tool. Trump himself said the move “gives us great power to negotiate,” suggesting the latter.
The tariffs represent the most substantial trade barriers in over 100 years, including a 10% blanket tariff on all imports, alongside steeper duties targeting key U.S. trading partners. Analysts warned that this could significantly drive up costs for American consumers, with some projections suggesting high-end iPhones could exceed $2,300 if Apple passes on the added expense.
Businesses rushed to respond. Automaker Stellantis announced temporary layoffs in the U.S. and plant closures in Canada and Mexico. Meanwhile, General Motors stated it would boost domestic production in response to the new trade climate.
Canadian Prime Minister Mark Carney condemned the decision, accusing the U.S. of abandoning its role as a champion of international economic cooperation. “The global economy is fundamentally different today than it was yesterday,” he said, unveiling limited countermeasures.
China, the world’s second-largest economy, vowed retaliation against the 54% U.S. tariffs on its exports. The European Union, facing a 20% duty, issued similar warnings. French President Emmanuel Macron urged EU countries to suspend investment in the U.S. as a form of protest.
While countries like Japan, South Korea, Mexico, and India held off immediate retaliation, they indicated that they would seek concessions through dialogue. Japan’s Prime Minister Shigeru Ishiba called the situation a “national crisis,” emphasizing the gravity of the economic threat.
International Monetary Fund (IMF) Managing Director Kristalina Georgieva also voiced concern, warning that the tariffs pose a “significant risk to the global outlook” amid already sluggish growth. “We urge the U.S. and its trading partners to resolve tensions constructively and reduce uncertainty,” she said.
Despite attempts by U.S. Commerce Secretary Howard Lutnick and trade adviser Peter Navarro to frame the tariffs as firm and non-negotiable, Trump contradicted them, telling reporters the measures are a tool to gain leverage: “The tariffs give us great power to negotiate… we’re taking it to a whole new level.”
Markets reeled in response. The Dow Jones Industrial Average dropped nearly 4%, its steepest single-day loss since June 2020. The S&P 500 fell almost 5%, while the Nasdaq tumbled close to 6%—its worst performance since the height of the pandemic in March 2020.
Major U.S. companies with international supply chains were hit hard. Nike shares sank 14%, while Apple dropped 9%. Asian markets also faltered, with Japan’s Nikkei falling 1.85% on Friday, extending Thursday’s 2.8% loss. Chinese markets were closed for a national holiday.
The sweeping tariffs, combined with retaliatory threats and volatile markets, have cast a shadow over the global economy, prompting warnings of disrupted supply chains, shrinking corporate profits, and a potential slide toward recession.
