Canadian Dollar Weakens as US Threatens New 50% Tariffs

The Canadian dollar weakened significantly against the U.S. dollar on Monday after U.S. President Donald Trump threatened to impose steep new tariffs on Canadian goods, escalating trade tensions between the two nations. The loonie fell approximately 0.6%, with the USD/CAD exchange rate trading around C$1.385, or 72.24 U.S. cents, according to market data.
Details of the Trade Dispute
The sell-off was triggered by a post on Truth Social in which President Trump threatened to raise tariffs on Canadian automobiles, car parts, and steel to 50% starting January 1, 2027. The move follows the breakdown of bilateral trade negotiations late last week and adds significant pressure on Ottawa.
Canadian officials have stated they will respond with retaliatory measures. Ottawa has pledged to match Washington's tariffs dollar-for-dollar, with new levies targeting U.S. steel, dairy, appliances, and electronics scheduled to take effect on September 8. The dispute introduces a new layer of cost and demand risk for Canadian exporters and companies with integrated North American supply chains.
Market Reverses Recent Gains
Monday's decline marks a sharp reversal for the Canadian dollar, which had reached a more-than-two-month high just last week. The currency's prior strength was supported by strong domestic economic data, including a 3.4% annualized GDP expansion in the second quarter and a gain of 75,000 jobs in July.
AdAccording to Karl Schamotta of Corpay Cross-Border Solutions, who spoke to the Financial Post, a recent U.S. Treasury bond buyback announcement had also been a major driver of the loonie's strength through mid-August. Analysts at City Index also noted that from a technical perspective, the USD/CAD pair was in oversold territory before Monday's rebound, suggesting the move was partly a short squeeze.
Broader Context
While the specific trade tensions are the primary driver of the loonie's weakness, broader market movements provided additional headwinds. The U.S. Dollar Index, which measures the greenback against a basket of currencies, was trading up 0.2% on the day.
Partially offsetting the negative pressure is the price of crude oil. As a major oil exporter, Canada's currency often finds support from elevated energy prices, which can provide a cushion even amid political or trade-related challenges.
