Nobel Economist Reveals US Weakness, Trump's Trade War with Canada Could Backfire
The trade war between the United States and Canada has entered an increasingly risky phase for both economies. US President Donald Trump on Monday (24/8/2026) threatened to raise tariffs to 50 percent on cars, trucks and vehicle parts made in Canada starting 1 January 2027, only days after Washington-Ottawa negotiations failed.
The new threat expands a dispute that had already drawn around 20 billion US dollars’ worth of Canadian products into 50 percent tariffs. Canada was scheduled to announce details of its retaliatory measures against Washington on Tuesday (25/8/2026).
Reuters reported on Monday, 24 August 2026, that Trump threatened 50 percent tariffs on all Canadian-made cars and trucks and their parts from the start of next year. The automotive dispute was one of the main causes of the failure of trade negotiations between the two countries.
The Associated Press reported on Monday, 24 August 2026, that Trump even asked Canadian leaders to follow the line set by Washington or face consequences he said would be far worse than the tariffs already imposed.
Canadian Prime Minister Mark Carney rejected the pressure. He said Canada remained open to negotiations but was not willing to take part in talks that placed his country as if it were beneath the United States.
An attitude at the negotiating table that treats Canada as if it were a subsidiary of the United States is unacceptable, Carney said, as reported by the Associated Press on Monday, 24 August 2026.
Carney also said the outcome of the negotiations led his government to believe Washington wanted major changes to Canada’s key industries, particularly automotive, steel and aluminium.
Canadian Finance Minister François-Philippe Champagne, along with a number of ministers, was scheduled to announce Ottawa’s retaliatory measures on Tuesday. Canada had previously stated it would retaliate against Washington’s tariffs dollar for dollar starting 8 September 2026.
The latest escalation forms the backdrop to analysis by American economist and 2008 Nobel Economics laureate Paul Krugman. He argued that America’s much larger economic size does not automatically mean Washington will emerge without losses if the dispute turns into a prolonged trade war.
In his writing published on Substack on Monday, 24 August 2026, Krugman predicted that Trump’s tariff strategy against Canada would ultimately run into problems because the two economies have been integrated for decades.
Krugman acknowledged that Canada’s position is more vulnerable in aggregate. Canada sends around 70 percent of its exports to the American market, so losing access or facing higher costs to enter the US market could deal a major blow to the Canadian economy.
