The loonie slipped 0.2% to trade at 1.4104 per U.S. dollar, equivalent to about 70.90 U.S. cents. The decline marked its lowest level since last Tuesday as investors reacted to the prospect of escalating trade tensions between Ottawa and Washington.
Market sentiment shifted after U.S. President Donald Trump unveiled a 50% tariff on a broad range of Canadian imports on Monday. The White House said the move was in response to what it described as Canada's discriminatory treatment of American-made vehicles, alcohol and dairy products. The new tariffs are scheduled to take effect on August 19 unless both countries reach a resolution before then.
Despite the announcement, analysts believe investors are viewing the latest tariff threat as part of ongoing trade negotiations rather than an immediate breakdown in economic relations between the two neighboring countries.
"The Canadian dollar’s move lower looks less like a clean tariff-premium story and more like a rates story for now," said Kevin Ford, FX & macro strategist at Convera.
He added, "The 30-day window on the latest U.S. tariff threat gives markets reason to treat this as another negotiating tactic rather than an immediate break in the trade relationship."
The tariff announcement prompted traders to trim expectations for additional interest rate increases from the Bank of Canada this year. Financial markets are now pricing in approximately 13 basis points of rate hikes by December, down from 16.5 basis points before the tariff announcement. Expectations had already softened from 18 basis points following the release of weaker-than-expected Canadian inflation figures earlier this week.
According to analysts, investors are increasingly focusing on broader macroeconomic factors rather than trade developments alone when assessing the Canadian dollar's direction.
"CAD is still being traded less as a standalone trade story and more as a macro expression of rates, growth divergence, and policy uncertainty," Ford said.
Meanwhile, the U.S. dollar strengthened against a basket of major global currencies as renewed geopolitical tensions in the Middle East pushed oil prices higher and revived fears that inflation could remain elevated for longer. U.S. crude oil futures climbed 2.5% to $85.31 per barrel during Tuesday's trading session.
Canada's bond market also reflected the shift in investor sentiment. Government bond yields declined across the curve, with the benchmark two-year yield falling 2.7 basis points to 2.812%. The spread between Canadian and U.S. two-year government bond yields widened further to 144.5 basis points—the largest gap since May 2025—highlighting growing expectations that Canadian interest rates may remain lower than those in the United States for an extended period.
The latest developments underscore how trade policy uncertainty, slowing inflation and changing interest rate expectations are combining to weigh on Canada's currency, even as markets continue to monitor whether the tariff threat ultimately results in a negotiated settlement or a deeper trade dispute.
