Bank of Canada would need to hike interest rates by up to 1.25% in full-blown tariff war, warns OECD

Canada’s economy may have ended 2024 on a high note, but that could all be undone as world trade is upended by Donald Trump’s tariff war, according to a new report by the Organization for Economic Co-operation and Development (OECD).

The OECD cut its growth forecast for Canada by more than half Monday, and predicted knock-on effects on inflation and interest rates that could result in the cost of borrowing rising and staying higher for longer if the country ends up facing 25 per-cent tariffs from the United States and a tit-for-tat retaliation. The analysis also accounts for tariffs exchanged between China and the United States, as well as Washington’s broad-based 25 per cent tariffs on steel and aluminum imports, which include Canada.

Here’s a look at what the OECD had to say about Canada.

The OECD now expects Canada’s gross domestic product (GDP) to grow by 0.7 per cent this year and next, down 1.3 percentage points from its previous projection in December.

The policy uncertainty created by tariffs will hit Canadian companies and households alike, forcing them to hold back spending on capital investment and durable goods, the report said.

Canada’s growth forecast was among the lower projections made by the OECD, which cut the outlook for most of its 38 nation members. Mexico, also in Trump’s tariff sights, was the only country where the OECD forecast the economy would contract over the year — shrinking 1.3 per cent.

The U.S. economy, meanwhile, is expected to grow 2.2 per cent this year, down 0.2 percentage points from the previous report, and 1.6 per cent next year, down 0.5 percentage points.

Canada’s growth prospects for this year and next dramatically improve if the U.S. extends tariff exemptions beyond April 2 for
