Trump Launches New Attack Against Canada’s Currency

U.S. President Donald Trump has opened another front in his trade war against Canada, suggesting that Canada is taking advantage of the U.S. through its currency. Both currencies are called the dollar, but Canada’s trades for less than the U.S. currency, and Trump argues this creates an unfair advantage.

More than 25 countries in the world have a currency called “the dollar”. Apparently, according to Donald Trump, 24 of them must be taking advantage of America because their dollars are different from his.

Canada has had a flexible exchange rate since 1970 (and also had a flexible rate between 1950 and 1962). It was one of the first industrial countries to abandon fixed exchange rates as the Bretton Woods financial system was dismantled in the early 1970s. The exchange rate is determined by numerous factors, including financial capital flows, comparative interest rates, comparative inflation, and investor expectations. The present exchange rate (about 72 cents U.S.) is well within the range of its historical fluctuations, and is in fact slightly stronger than when Trump took office for the second time in January 2025.

Of course, the fact that America’s dollar is used (for now, anyway) as a global reserve currency, hence allowing the US to run trade deficits every year for 50 years, is a unique privilege, not a sign of victimisation. America consumes far more than it produces, year after year. But inflows of capital from other countries, and holdings of U.S. dollars by foreign investors and institutions, allow the U.S. to maintain this ongoing trade deficit.

The world (including Canada) supplies the US with trillions of dollars of purchasing power every year, allowing this permanent trade deficit to continue. We explained this relationship in our research report, Who’s Subsidizing Whom? Over the past decade, new purchases of U.S. debt (mostly from the federal government) have almost perfectly offset the cumulative U.S. bilateral trade deficit with Canada over that same period. In short, it is Canada subsidizing America (with transfers of money), not the other way around.
