Ottawa's retaliation reaching 50 percent on CA$27.6 billion of American products, triggered by the breakdown of trade negotiations, lifted the dollar as currency markets braced for prolonged conflict.

Canada imposed retaliatory tariffs of up to 50 percent on CA$27.6 billion of U.S. goods Tuesday after trade talks collapsed, pushing the dollar off session lows as traders sought haven exposure.
"Canada wants a durable agreement with Washington but will not accept conditions that undermine the competitiveness of key Canadian industries," Prime Minister Mark Carney said, as Ottawa's finance department framed the duties as a "dollar for dollar" response to U.S. levies.
The new measures double Canadian tariffs on U.S. steel, aluminum and iron products to 50 percent and add duties on hundreds of goods including dairy, agricultural equipment, paper, household appliances and electronics. They follow U.S. tariffs of 50 percent on roughly $20 billion of Canadian wine, hockey sticks and other products that took effect Aug. 22 under a rarely cited Depression-era law. Existing Canadian counter-tariffs, including 25 percent on autos, remain in force.
The escalation converts weeks of threats into an active trade conflict between partners that exchanged more than $715 billion in goods last year, according to the U.S. Trade Representative's office. With no new talks scheduled and both governments blaming each other for the breakdown, traders are pricing continued dollar strength and elevated volatility across EUR/USD, GBP/USD, USD/CAD and USD/JPY.
The breakdown followed a dramatic reversal. Trump announced on Aug. 18 that Washington and Ottawa had reached preliminary terms and gave negotiators several days to settle remaining details. Instead, the talks collapsed, with each side accusing the other of making untenable last-minute changes to a deal that was nearly complete. The U.S. tariffs that followed were imposed hours after the failure, escalating a conflict that began with Washington's global tariff offensive in April 2025.
The dollar's rebound from session lows reflects traders rotating into U.S. assets as the trade conflict deepens. USD/CAD has been the most direct beneficiary, with the Canadian dollar absorbing the shock of tariffs that target roughly the same value of trade affected by U.S. duties on about $20 billion of Canadian products. EUR/USD and GBP/USD have weakened against the dollar's haven bid, while USD/JPY has tracked broader risk dynamics as traders weigh implications for global growth.
The pattern echoes earlier phases of the conflict. When Washington launched its global tariff offensive in April 2025, the dollar strengthened as investors favored U.S. assets over those of trading partners more exposed to disruption. Canada has now committed CA$32.5 billion in total support for businesses and workers — the CA$25 billion package announced in response to the April tariffs plus an additional CA$7.5 billion unveiled last month — a sign Ottawa expects the disruption to persist.
The stakes extend beyond currency markets. U.S. agriculture depends on integrated North American supply chains for farm equipment, replacement parts, fertilizer and transportation. Michigan and Ohio face significant exposure through manufacturing and export ties, while the broader Midwest could feel the effects if the dispute expands beyond current categories. U.S. Trade Representative Jamieson Greer has indicated additional tariffs and even restrictions on certain Canadian imports remain possible, though Washington has not announced timing.
Trump has also threatened restrictions on Canadian aircraft maker Bombardier, which relies on more than 2,800 U.S.-based suppliers. Both Kansas senators have pushed back, citing Bombardier's more than 1,200 jobs in Wichita. House Speaker Mike Johnson has publicly called for negotiations to resume, and Carney has left the door open to a deal.
But with Canadian tariffs now in force and no date set for new talks, businesses are no longer planning around a hypothetical threat — they are operating under actual duties that could remain unless both governments find a path back to the table. For currency traders, the question is whether the dollar's haven bid persists through further escalation or fades if negotiations restart.
