Canada Trade Collapse Shows the Cost of Overusing U.S. Financial Power

The collapse of Canada-U.S. trade talks this week highlights how American economic dominance can become political leverage, with new 50 percent tariffs prompting Canadian retaliation and suspended negotiations. Prime Minister Mark Carney called the last-minute American demands "unfair" and "uneconomic," announcing dollar-for-dollar countermeasures. The dispute follows U.S. sanctions on International Criminal Court judges, which disrupted their banking and travel, illustrating Washington's reach through global financial systems. The sale of Canadian payment processor Moneris to a U.S. firm raises concerns about critical infrastructure exposure. As allies reassess dependence, overusing coercive power risks eroding confidence in American systems, prompting shifts toward alternatives.
