Turn your mortgage into a wealth-building tool. Smith Manoeuvre strategies, tax-smart planning, and honest math from two Canadian mortgage strategists.
US tariffs won't show up in your mortgage rate the way you think
The Bank of Canada lowered its overnight rate five times between June and December 2024, and the consensus view heading into 2025 was that fixed mortgage rates would keep drifting downward. Then the tariff threats started, and the bond market stopped cooperating. The five-year Government of Canada bond yield, the primary driver of fixed mortgage rates in this country, climbed back above 3% in early 2025 even as the policy rate held steady. The disconnect isn't a mistake. It's the market pricing in a problem that hasn't arrived yet but is visible from here.
Tariffs don't directly set mortgage rates. They influence the conditions that set mortgage rates, and the path from one to the other runs through inflation, currency weakness, and the impossible position tariffs put the Bank of Canada in when they try to manage both at once.
Tariffs will push inflation higher through import costs
A broad 50% tariff on Canadian goods entering the U.S. would raise costs for Canadian exporters immediately. Roughly 67.3% (October 2025) to two-thirds (H1 2026) of Canadian exports go south, so the impact isn't confined to a single sector. Companies absorbing the cost take a margin hit. Companies passing it on raise prices. Either way, the domestic economy gets the pressure.
Statistics Canada tracks cross-border trade at approximately $3.5 billion CAD per day. When that flow gets taxed, the cost doesn't stay at the border. It moves through supply chains, inventory pricing, and eventually consumer goods. The Bank of Canada's 2% inflation target becomes harder to defend when import costs are rising for reasons monetary policy can't address. This is cost-push inflation, and it persists even when demand is cooling.
The bond market doesn't wait for the inflation data to confirm the problem. It prices in the risk the moment tariff implementation looks credible. That's why yields on five-year bonds can climb while the overnight rate stays flat. The market is anticipating that the Bank will have to keep rates higher, longer, to prevent inflation from breaking above the control range, and fixed mortgage rates, which track bond yields, move accordingly.
The currency complicates everything
A weaker Canadian dollar makes our exports cheaper for American buyers, which partially offsets the tariff's impact on competitiveness. But it also makes everything we import more expensive, and that includes the goods Canadians buy every day. Market analysts have floated scenarios where a 10% increase in broad tariffs could push the CAD down to the $0.68, $0.70 range against the USD.
That kind of depreciation puts the Bank of Canada in a bind. Lowering rates to stimulate a slowing economy would normally be the response to a trade-induced slowdown. But lowering rates when the currency is already weak risks accelerating the slide, which feeds more inflation through import costs. The result is that the Bank may hold rates higher than the domestic economy alone would justify, simply to defend the currency. Fixed mortgage rates, in turn, stay elevated even if the housing market is cooling.
The lag between shock and response
Bond yields react to tariff news within days. The real-world economic impact, slower GDP growth, rising unemployment, weaker housing demand, takes months to show up in the data. By the time the recessionary effects are clear, mortgage rates may have already spiked on the expectation of persistent inflation.
The other timing issue: CUSMA comes up for review in 2026. That adds a layer of structural uncertainty to the long-term rate outlook that wasn't there a year ago.
If you locked in a fixed rate in late 2024 expecting steady declines into 2026, the tariff environment has changed the trade-off. Variable rates tied to the policy rate might eventually benefit if a slowdown forces the Bank to cut aggressively. Fixed rates, meanwhile, are being held up by a bond market that sees inflation risk before it sees relief.
The mortgage rate you're being quoted today isn't reacting to tariffs. It's reacting to what the tariffs are likely to force the Bank of Canada to do, and that calculation is already baked in.
