When the US Fed Raises Rates, What Happens to Mortgages in Canada?
The US Federal Reserve just raised interest rates, and many Canadians are wondering what that means for their mortgages. The short answer is that history shows the Bank of Canada almost always follows the Fed's lead. Since 1996, we've seen this pattern play out five out of five times. While a Bank of Canada rate hike isn't immediate, the effects are already here. In the last two weeks alone, rising government bond yields have pushed fixed mortgage rates up by 0.25% to 0.50%. This isn't a future problem. It's happening now. For anyone buying a home, renewing a mortgage, or holding a variable rate, this US rate hike is a direct signal that changes are coming to the Canadian market. Based on historical data, we can project a Bank of Canada rate increase is likely within the next two to five months, putting the spotlight directly on their upcoming meetings.
Key Takeaways
- History Repeats: Since 1996, the Bank of Canada has followed the US Fed's rate hikes five out of five times. The question isn't if, but when.
- Fixed Rates Are Already Up: Your fixed mortgage rate isn't tied to the Bank of Canada's overnight rate. It's priced off government bond yields, which are correlated with US Treasuries. These yields have already rallied, increasing fixed rates by as much as 0.50% in the last few weeks.
- A BoC Hike Is Likely Soon: The historical average delay between a Fed hike and a BoC hike is two to five months. This projects a potential increase between November 2026 and February 2027, with market predictors eyeing the December 9th meeting.
- Variable Isn't a Bad Bet: Despite the likelihood of a rate hike, my analysis shows a variable-rate mortgage still saves money in three out of five potential scenarios. It's a bet on oil prices coming down, but it's not an extreme call.
How Does a US Rate Hike Affect Canadian Mortgage Rates?
A US rate hike impacts Canadian mortgages through two primary channels: government bond yields, which immediately affect fixed rates, and the pressure it puts on the Bank of Canada to adjust its own policy rate, which governs variable-rate mortgages. Fixed mortgage rates are priced based on the Government of Canada's 5-year bond yield, which is heavily correlated with US Treasury yields. When US rates go up, investors often move money to higher-yield US assets, causing our bond yields to rise to compete. The Canadian 5-year bond yield climbed to 3.69% on September 23, 2026, according to Wowa.ca, pushing lenders to increase their fixed-rate offerings. Secondly, a wider gap between US and Canadian rates weakens our dollar. The loonie dropped from 72.35 US cents on September 10th to 71.32 on September 21st. A weaker loonie makes imports more expensive, fueling inflation, which the Bank of Canada is mandated to control, often by raising its own interest rate.
What's the Historical Link Between the Fed and the Bank of Canada?
Since 1996, the Bank of Canada has followed the US Fed's rate hikes five out of five times, with a typical delay of two to five months. In 1997, the BoC followed a March Fed hike in June, a three-month lag. In 1999, it took just over four months. In 2004, the delay was about 2.3 months. The longest gap was in 2015, when it took 19 months for Canada to follow suit, but that was a unique situation where the BoC was cutting rates in response to a sharp drop in oil prices. Most recently, in 2022, Canada actually moved just two weeks before the Fed. Averaging these out, the most probable timeline for the Bank of Canada to increase its rate is between two and five months from the recent Fed decision. This would land us somewhere between November 2026 and early February 2027, with the December 9th Bank of Canada meeting sitting right in the middle of that window. This historical pattern is the single best indicator we have for predicting the Bank's next move.
Should I Choose a Fixed or Variable Rate in 2026?
The decision depends on your risk tolerance, but the math shows a variable-rate mortgage is likely to save you money in most scenarios, even with potential rate hikes. On a $500,000 loan, if the Bank of Canada does nothing, a variable rate based on today's discounts would save you approximately $21,170 over the term compared to a fixed rate. If the BoC hikes three times starting in December, variable still saves you about $5,289. It's only in the worst-case scenarios, like the ten rapid hikes we saw in 2022, that variable would cost you more. A bet on a variable rate today is largely a bet that oil prices will come down, preventing inflation from getting out of control. With the lowest advertised insured 5-year variable rate at 3.45% as of September 23, 2026, according to True North Mortgage, compared to 4.39% for a fixed rate, the initial savings are significant. If you can handle potential payment increases, variable remains a strong strategic option. You can learn more about how to pick your mortgage term without predicting rates in our detailed guide.
What Should I Do If My Mortgage Is Renewing Soon?
If your mortgage is renewing in the next four to six months, you need to get a rate hold from a broker immediately. A rate hold locks in today's interest rate for up to 120 days, and sometimes even 180 days, protecting you from the increases we're already seeing in the fixed-rate market. Do not simply sign the renewal letter your current bank sends you. They rarely offer their most competitive rates to existing clients. Shopping around is critical. We can analyze your situation and compare offers from multiple lenders to ensure you're getting the best possible terms. Also, pay attention to the term length. Just a few weeks ago, a 3-year fixed was much cheaper than a 5-year. Today, they are very close in price, and in some cases, the 3-year is even higher. A 2-year term might offer a discount, but you sacrifice long-term certainty. We can run the numbers to see what makes the most sense for your specific financial plan.
What If I'm Buying a Home in the Next 4 Months?
Get a properly underwritten pre-approval and a rate hold now. This is massive. A rate hold doesn't just secure your interest rate; it secures your borrowing power. What you qualify for today is the maximum you can borrow. If rates go up before you buy, your maximum qualification amount will go down. By locking in a rate hold, you could potentially qualify for more house than you would in a few months. It's essential to get a pre-approval that has been fully underwritten, not just a quick online calculator estimate. An underwriter reviews your income, down payment, and credit documents to give you a firm approval. This gives you the confidence to go shopping for a home knowing exactly what you can afford and that your financing is secure, even if the market shifts.
Frequently Asked Questions
If the Bank of Canada hasn't raised rates, why did my fixed rate go up?
Fixed mortgage rates are not directly tied to the Bank of Canada's overnight rate. Instead, they are priced based on the Government of Canada's 5-year bond yield. These bond yields are traded on the open market and are heavily influenced by international factors, especially the US Treasury market. When the US Fed raises its rates, it makes US bonds more attractive, which often causes Canadian bond yields to rise to stay competitive. This increase in the cost of funds for lenders is passed on to consumers as higher fixed mortgage rates.
How long does it usually take for the Bank of Canada to follow a US Fed rate hike?
Based on historical data going back to 1996, the Bank of Canada typically follows a US Fed rate hike within two to five months. There have been exceptions, such as a 19-month lag starting in 2015 due to a collapse in oil prices, and an instance in 2022 where Canada moved just before the Fed. However, the consistent pattern across five separate hiking cycles shows a strong correlation and a predictable, though not exact, timeline. This history suggests a high probability of a Canadian rate hike before spring 2027.
Is a variable-rate mortgage too risky right now?
A variable-rate mortgage carries more risk than a fixed rate, but it may not be as risky as it seems. My analysis of a $500,000 mortgage shows that even with three quarter-point rate hikes from the Bank of Canada, a variable rate would still save you over $5,000 compared to current fixed rates. The risk is that rates rise more than expected. A borrower choosing variable should be comfortable with potential payment fluctuations and have a budget that can absorb them. It's a calculated risk that has historically paid off for many Canadians.
What is a rate hold and why is it important?
A rate hold is a guarantee from a lender to give you a specific interest rate for a set period, typically 90 to 120 days, while you finalize a home purchase or mortgage renewal. It's incredibly important in a rising rate environment because it protects you from any rate increases that happen after your hold is secured. If rates go up, you get your lower, held rate. If rates go down, most lenders will give you the new, lower rate. It's a free insurance policy against rising interest costs and can save you thousands of dollars.
What are the key economic indicators to watch?
The three main things to watch are the Consumer Price Index (CPI), oil prices, and the value of the Canadian dollar. The Bank of Canada's next decision on October 28th will be heavily influenced by the September CPI report, which comes out on October 19th. If inflation, particularly CPI excluding gasoline, continues to rise, it puts more pressure on the Bank to hike rates. Similarly, high oil prices and a weak Canadian dollar can also contribute to inflation, increasing the likelihood of a rate increase in the coming months.
The relationship between US and Canadian interest rates is complex, but the historical pattern is clear. If you're renewing, buying, or on a variable rate, now is the time to be proactive. Don't wait for the Bank of Canada's announcement, as the market has already started to move. To see what rates you could qualify for today, use our online tool at rate.getflowmortgage.ca.
