Inflation caused by tariffs could force the Bank of Canada to raise interest rates by up to 1.25 percent, a level that exceeds those in many other countries, a new report suggests.
Interest rates would rise by 0.25 percent to 0.5 percent on average in other “advanced and major emerging market economies,” the OECD said.
The growth outlook for most of the 38 countries was cut back in the March 17 report, with global growth predicted to slow to 3.1 percent in 2025 and 3 percent in 2026 due to higher trade barriers and geopolitical and policy uncertainty impacting investment and household spending.
GDP growth in Canada is expected to slow from 1.5 percent in both 2025 and 2026 to 0.7 percent in both years. The report projects that inflation in Canada will also be at 3.1 percent in 2025 and 2.9 percent in 2026.
If the United States hits all imports from Canada and Mexico with 25 percent tariffs, and the countries respond with retaliatory tariffs, it will be “particularly costly for Canada and Mexico” due to their high proportion of trade with the United States, the report said.
The United States will also see its GDP growth slow to 2.2 percent in 2025 and 1.6 percent in 2026, while inflation is projected to be 3 percent in 2025 and 2.6 percent in 2026.
The United States imposed 25 percent tariffs on Canada and Mexico on March 4, but implemented a one-month exemption for products compliant with the United States-Mexico-Canada Agreement (USMCA). If this pause were to be extended, the report projects inflation would be lower in all three countries, reaching 2.6 percent in 2025 and 2.5 percent in 2026 in Canada, and 2.7 percent in 2025, and 2.5 percent in 2026 in the United States.
The report said tariff revenues will amount to roughly 1.2 percent of U.S. GDP and 1.5 percent of Canada’s GDP, but this would be “offset by the associated decline in activity and higher debt servicing costs.” It said the impact of tariffs on public finances could mean there is “little scope” to use these revenues to lower taxes or increase spending.
Ottawa has said that revenues collected from retaliatory tariffs will be used to support Canadians harmed by U.S. tariffs.
