Canada and the United States have entered another period of heightened trade tensions, and many Canadians are wondering what it could mean for the economy, inflation and, ultimately, mortgage rates.
For homeowners, homebuyers and anyone with a mortgage, the big question is simple: could the current trade war cause mortgage rates to go up, or could it actually lead to lower rates?
The answer isn’t straightforward. Tariffs can put upward pressure on prices while simultaneously slowing economic growth. Those two forces can push interest rates in opposite directions.
Here’s how I look at the situation, what I’m watching, and what it could mean for Canadian borrowers.
What’s Happening With the Canada-U.S. Trade War?
Trade tensions between Canada and the United States escalated again in August 2026. Effective August 22, the United States imposed a 50% tariff on approximately $27.6 billion of Canadian goods after trade negotiations were suspended. Canada responded by announcing matching counter-tariffs covering approximately $27.6 billion of U.S. imports, with those measures scheduled to take effect September 8.
Canada’s counter-tariffs will range from 15% to 50%, depending on the product, and will affect sectors including steel, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics.
The situation remains fluid. Additional tariffs, exemptions or renewed negotiations are all possible.
For Canada, this matters because our economy is deeply integrated with the United States. Changes in trade policy can affect exporters, manufacturers, businesses, workers, consumers, investment and supply chains across the country. And when those parts of the economy change, the outlook for interest rates can change too.
Where Do Interest Rates and the Economy Stand Today?
Before looking at what the trade dispute could do next, it helps to understand where we are starting.
The Bank of Canada has held its policy rate at 2.25% since October 2025. At its July 15 meeting, the Bank said economic growth appeared to be resuming, even though U.S. trade policy remained a headwind and uncertainty was still elevated.
The most recent economic data have been mixed, but there are still signs of resilience. Employment increased by 75,000 in July and the unemployment rate fell to 6.4%, its lowest level in two years. At the same time, headline inflation rose to 3.0% in July, although the all-items CPI excluding gasoline was considerably lower at 2.2%.
That puts the Bank of Canada in an interesting position. There are reasons to be cautious about inflation, but also reasons to be concerned that a prolonged trade dispute could weaken growth. The latest escalation adds another layer of uncertainty to that balance.
Important timing note: At the time of writing on August 31, the Bank of Canada’s next interest-rate announcement is Wednesday, September 2 – just two days away. What the Bank says about inflation, economic growth and the latest trade escalation could change parts of this outlook. I will be watching that announcement closely and may revisit this article afterward if the Bank materially changes its message.
Why Does a Trade War Matter for Interest Rates?
The Bank of Canada doesn’t set interest rates based on tariffs themselves. It looks at how tariffs and trade disruptions affect the broader economy.
Two of the biggest factors to watch are inflation and economic growth. The challenge is that a trade war can affect both – and sometimes in opposite directions.
1. Tariffs Can Push Inflation Higher
Tariffs can create inflation in several ways. Canada’s retaliatory tariffs can directly increase the cost of certain goods imported from the United States. Businesses may also face higher costs as supply chains adjust, and a weaker Canadian dollar could make imported products more expensive.
Some of those additional costs can eventually be passed on to consumers through higher prices.
However, the Bank of Canada is unlikely to react to every one-time increase in the price of a tariffed product. The bigger concern is whether those price increases become broad-based and persistent – for example, if higher costs begin feeding into many other goods, services and inflation expectations.
If underlying inflation remains elevated or becomes more persistent, the Bank of Canada may have less room to reduce its policy rate.
Higher and more persistent inflation = less room for rate cuts and potential for increases.
This is one reason the trade dispute could keep interest rates higher for longer.
2. But a Trade War Can Also Slow the Economy
There’s another side to the story. U.S. tariffs make affected Canadian products more expensive for American buyers, which can reduce demand for Canadian exports. Trade uncertainty can also cause businesses to delay investment or hiring, while Canadian counter-tariffs can increase costs for businesses that rely on U.S. inputs.
Over time, that can contribute to:
– Lower exports
– Reduced business investment
– Slower economic growth
– Pressure on tariff-exposed industries
– Potential job losses
– Weaker consumer spending
If the trade dispute becomes a significant drag on the Canadian economy, the Bank of Canada could face greater pressure to support economic activity – particularly if inflation is also moving back toward target.
Trade war + weaker growth + contained inflation = a stronger case for lower rates.
So Which Way Will Interest Rates Go?
This is where things get complicated. The Bank of Canada may have to balance two competing risks: higher or more persistent inflation on one side, and weaker economic growth and employment on the other.
If inflation becomes the bigger concern, the Bank may need to increase rates. If economic weakness becomes the bigger concern and inflation remains contained, the case for future rate cuts becomes stronger.
My view is that the most important question is not simply whether tariffs are imposed. It is whether the trade dispute causes a meaningful deterioration in employment and economic growth without creating persistent inflation. That combination would give the Bank more reason to lower rates. If tariff-related costs and other global pressures keep inflation elevated, the Bank may be forced to stay on the sidelines longer or increase rates.
That’s why I would not try to predict mortgage rates based on a single trade headline. The Bank will be looking at the cumulative effect on inflation, employment, consumer spending, business investment and overall economic growth.
What Could This Mean for Variable Mortgage Rates?
Variable mortgage rates are more directly influenced by the Bank of Canada’s policy rate. When the Bank changes its overnight rate, lenders typically adjust their prime rates as well.
If the Bank of Canada lowers its policy rate, variable mortgage rates would generally move lower. Depending on the mortgage structure, a borrower’s payment may also decline. Some variable-rate mortgages have fixed payments, while adjustable-rate mortgages typically change their payments as prime changes.
If the Bank holds rates steady, variable mortgage rates would generally remain relatively stable. If persistent inflation eventually required tighter monetary policy, variable rates could move higher.
For variable-rate borrowers, the key things I am watching are:
– Inflation – especially whether price pressures are broad-based and persistent
– Employment and unemployment
– Economic growth and consumer spending
– The Bank of Canada’s policy decisions and guidance
– The trade war influences all of these, but it is only one part of the picture.
What About Fixed Mortgage Rates?
Fixed mortgage rates work differently. They do not simply move up or down with the Bank of Canada’s overnight rate.
Fixed mortgage pricing is heavily influenced by the bond market, particularly Government of Canada bond yields. Bond yields can move based on expectations for inflation and economic growth, but they are also influenced by U.S. Treasury yields, global financial markets, energy prices and broader investor sentiment.
That means fixed mortgage rates can move even when the Bank of Canada has not changed its policy rate.
If investors become more concerned about inflation – or if global bond yields move higher – Canadian bond yields can rise as well, putting upward pressure on fixed mortgage rates. On the other hand, if investors become more concerned about a significant economic slowdown, bond yields can fall, potentially creating downward pressure on fixed rates.
This is why borrowers shouldn’t assume that a Bank of Canada rate cut automatically means every mortgage rate will fall. Variable rates and fixed rates can move for different reasons – and sometimes in different directions.
What Should Homebuyers and Homeowners Do?
I wouldn’t make a major mortgage decision based on trying to predict the outcome of the trade war – or the next move from the Bank of Canada.
If you are choosing between fixed and variable today, the better questions are how much rate uncertainty you are comfortable with, how long you expect to keep the mortgage, how important payment certainty is to you, and how much flexibility you may need during the term.
If your mortgage is coming up for renewal, start reviewing your options early. Fixed and variable rates can move for different reasons, and your existing lender’s renewal offer is not necessarily your best option.
The right mortgage strategy should be based on your individual circumstances and financial goals – not on trying to guess exactly what Washington, Ottawa or the Bank of Canada will do next.
The Bottom Line
The latest escalation in the Canada-U.S. trade war adds another layer of uncertainty to the Canadian interest-rate outlook.
Tariffs can increase prices, which can make it harder for the Bank of Canada to lower rates. But they can also weaken exports, investment, employment and economic growth – which can eventually create pressure for lower rates.
Which force wins out will matter far more than the tariffs themselves.
For variable-rate borrowers, I will be watching inflation, employment and the Bank of Canada closely. For fixed-rate borrowers, I will also be watching the bond market and broader global interest-rate trends.
Most importantly, I wouldn’t structure a mortgage around trying to predict exactly where rates will be six months from now. The better approach is to choose a mortgage that works for your finances today while giving you enough flexibility for whatever comes next.
