Mortgages and Inflation: How Do They Affect Each Other?

This piece was originally published on May 11, 2022 and was updated on October 9, 2026. 

While Canada’s inflation rate has come down from its peak of 8.1% in June 2022, it has crept back up lately. Headline inflation held at 3.0% in August 2026, matching July and sitting above the Bank of Canada’s 2% target. Much of that is gasoline, which was up 22.8% from a year earlier; excluding gasoline, prices rose 2.4%, and the Bank's preferred core measures are close to 2%. Although we might not be paying eight bucks for a loaf of bread just yet, things still aren’t exactly cheap. Unfortunately, an increased inflation rate doesn’t just affect your shopping cart – it can also hit your mortgage. Keep reading to find out how inflation and mortgage rates are connected and what you can do to avoid being caught off guard.

What is the relationship between inflation and interest rates on mortgages?

Inflation is a natural part of a growing economy, but when it rises too quickly, it can create problems. As everyone races to raise prices to try to keep up, the value of the dollar can drop sharply. Left unchecked, it can cause a recession. In extreme cases, currencies have become completely worthless – to the point where it’s cheaper to literally burn cash than buy firewood.

The Bank of Canada has a mandate to keep inflation at a target rate of 2% per year to maintain economic stability. To do this, the Bank adjusts its overnight rate, which is the cost for banks to borrow money from each other (literally) over one night. When BoC raises this benchmark rate, lenders also increase mortgage rates to cover their costs.

How inflation affects variable mortgage rates

For variable-rate mortgages, the connection to inflation is direct. These rates are expressed in relation to the lender's prime rate, which usually changes when the BoC adjusts the overnight rate. 

For example, let’s say your lender is offering variable mortgage rates at Prime – 1.05%. Because the prime rate is currently 4.45%, you would pay an actual mortgage rate of 3.40% (4.45% - 1.05%). If the BoC raises the overnight rate by 25 points (0.25%), and the bank raises its prime rate by the same amount, your mortgage rate will go up to 3.65%.

How inflation affects fixed mortgage rates

Unlike variable-rate mortgages, fixed mortgage rates aren’t directly tied to the Bank of Canada’s overnight rate. However, they still respond to inflation and interest rate changes. Fixed rates are more closely related to bond yields, which typically rise when inflation is expected to jump. When inflation increases, bond investors demand higher returns to compensate for the loss of money’s value. This causes bond yields to go up, which in turn pushes fixed mortgage rates higher as well.

How do interest rates affect inflation?

It’s not just inflation that impacts mortgage rates – interest rates can also influence inflation. Here’s how:

1. Impact on consumer spending: High mortgage rates make it more expensive to borrow money, which can slow down spending in the housing market and other areas of the economy. When fewer people can afford to buy homes, it reduces overall demand in the housing market, which in turn can lower inflationary pressure in housing-related costs, like rent and home prices.
   
   
2. Slower economic growth: Higher mortgage rates generally lead to higher monthly payments for homeowners. This can reduce disposable income, causing people to cut back on spending. When consumers spend less, it can reduce demand for goods and services, which may help slow down inflation over time.

What do inflation and rising interest rates mean for my mortgage?

If you have a variable-rate mortgage, your costs came down after the Bank of Canada's nine rate cuts between June 2024 and October 2025. Since then the Bank has held its overnight rate at 2.25% for seven decisions in a row, most recently on September 2, 2026, so prime has stayed at 4.45%. That stability may not last. On September 2 the Bank said upside risks to inflation have increased, and its next decision is on October 28, 2026. Forecasters are split on whether it will hold or raise rates, but a hike would push variable-rate payments or interest costs up again.

While variable-rate mortgages are typically lower than fixed-rate mortgages, that is true again today. With the current overnight rate at 2.25%, the best 5-year variable mortgage rate is 3.40%, compared with 4.34% for the best 5-year fixed rate (as of October 9, 2026).

If you have a fixed-rate mortgage, your payment will remain the same until your mortgage is up for renewal. However, when it’s time to renew, you may face a higher rate. For instance, if you took out a 5-year fixed mortgage in 2021 at 1.68%, you’ll be renewing at today’s best 5-year fixed rate of 4.34% — more than double your previous rate.

How are the Canada–U.S. trade war and higher energy prices impacting inflation and mortgages?

Two forces are behind most of the recent movement in mortgage rates: an escalating trade conflict between Canada and the U.S., and higher energy prices linked to the war in the Middle East.

On trade, the U.S. imposed 50% tariffs on about $28 billion worth of Canadian products in August 2026. Canada responded with dollar-for-dollar counter-tariffs of 15% to 50% on more than 700 U.S. products ($27.6 billion), which took effect on September 8. Trade talks between the two countries have broken down. Tariffs pull in two directions: they can push prices up, but they can also weigh on growth, jobs and spending.

The impact has been most noticeable on fixed mortgage rates, which are influenced by bond yields. The Government of Canada five-year bond yield rose from 3.33% at the end of August to 3.69% in September and has stayed elevated. As a result, the lowest five-year fixed rate on Ratehub.ca climbed from 4.09% to about 4.24% in September, and it was 4.34% on October 9.

In the case of variable rates, the Bank of Canada held its overnight rate at 2.25% on September 2, saying upside risks to inflation have increased while the new tariffs make growth prospects more uncertain. With headline inflation at 3.0% and energy prices elevated, a rate hike is now a real possibility, and lenders may also reduce their variable-rate discounts. Forecasters are divided: some expect a hike on or shortly after October 28, while others expect the Bank to hold through the rest of the year.

Historically, variable-rate holders have usually paid less interest than fixed-rate holders, and variable rates are cheaper than fixed rates again today. But if the Bank starts raising rates, that gap could shrink. If you're thinking about switching from a variable to a fixed mortgage, consistent payments and stability should remain your primary motivation.

What can I do to navigate fluctuating mortgage rates?

Fixed rates have been climbing since August, and a Bank of Canada hike is possible, so rates may not be done rising. Prior to the Great Recession of 2008-09, rates bobbed around the 5%-6% range. In the 1970s and 1980s, mortgage rates of 10%-12% were typical. Since it’s not inconceivable that mortgage rates could return to those levels, you may want to start making changes now to prepare.

Here are a few things you might want to do to prepare for rising mortgage rates:

• Start making extra mortgage payments: For the past few decades, low mortgage rates have made it easier to carry a larger mortgage balance. However, with rates under upward pressure, now may be the time to make extra payments to reduce your principal. Lowering your mortgage balance will help you save money on interest in the long run. Use a mortgage payment calculator to estimate how much your payment might be at a higher rate. If your regular payments increase due to rising rates, the extra payments you’ve made will reduce the overall amount you owe, making future payments more manageable.
• Renew your fixed-rate mortgage early: If you’re currently in a fixed-rate mortgage, you might want to explore renewing early. This could be a good strategy if your current term is close to ending, especially since fixed rates have been rising along with bond yields. If you’re close to your mortgage renewal date, consider shopping around and getting a rate hold. This means you can lock in today's rate for up to 120 days, even if you don’t officially renew your mortgage until later. A rate hold can help you avoid higher rates if they continue to rise in the coming months.
• Consider refinancing to a more affordable option: If you're finding your current mortgage payments increasingly difficult to manage, refinancing your mortgage to a lower rate could help. This option could be particularly useful if you have significant equity in your home and want to take advantage of more manageable monthly payments if rates rise further. However, refinancing often comes with some upfront costs. 
• Call your mortgage broker or lender: If you’re concerned that rising inflation and mortgage rates will make it difficult for you to keep up with your mortgage payments, proactively reach out to your mortgage broker or lender to discuss your options. They will be willing to work with you to find solutions to keep your payments affordable. For example, you may be able to lower your payments by changing your payment frequency, extending your amortization, or switching to a new lender. You can use our amortization calculator to see how adjusting your amortization period length might affect your monthly payments. Be sure to ask questions and remember you don’t necessarily have to accept the first offer.
• Do nothing: If rates keep rising, a variable-rate mortgage will become more expensive no matter what you do, while a fixed-rate mortgage won't change until renewal. Trying to time the market is nearly impossible. You might simply choose to carry on as you already are and let the current carry you rather than waste energy trying to swim against it.

The bottom line

After a long stretch of rate cuts, inflation near 3%, higher energy prices, a trade war and climbing bond yields are a reminder that mortgage rates can move up as well as down. Rather than trying to time the market, your best course of action may be to start making additional mortgage payments to get used to a higher price and reduce interest payments for your future self. 

If things get really out of hand, ask for the help you need. Get in touch with your lender or mortgage broker for solutions that fit your unique needs.
