Why fixed rates are rising when the Bank hasn't moved

Fixed mortgage rates are going up because they follow Government of Canada bond yields, and those yields have climbed this fall, even though the Bank of Canada has held its policy rate at 2.25% since October 2025. When the 5-year bond yield rises, it costs lenders more to fund 5-year fixed mortgages, so they raise their rates. As of October 22, 2026, all of the Big Six banks have done exactly that.

Key takeaways

• The Bank of Canada's rate drives variable mortgages and HELOCs. Bond yields drive fixed mortgages.
• The 5-year Government of Canada bond yield was around 3.62% on October 7, compared with under 1% when many 2020 and 2021 mortgages were signed.
• Big banks raised fixed rates by roughly 10 to 50 basis points since early September.
• Buyers and renewers can protect themselves with a rate hold, which commonly lasts up to 120 days.
• The October 28 Bank of Canada decision isn't known yet, and a hold wouldn't automatically lower fixed rates.

Why are fixed mortgage rates going up?

Fixed rates are rising because the bond market has pushed yields higher, and lenders price fixed mortgages off those yields. Money.ca reports that every Big Six bank has raised fixed rates since early September, with TD and RBC up as much as 40 to 50 basis points on some terms. RBC also trimmed its variable-rate discounts.

None of that needed a move from the Bank of Canada. Its policy rate is still 2.25%, and prime is still 4.45%.

What is a bond yield, in plain English?

A bond yield is the return investors get for lending money to the government. When you buy a 5-year Government of Canada bond, you're lending Ottawa money for five years, and the yield is your annual return.

Yields move every day based on what investors expect. If they think inflation will stay high, or that interest rates will rise, they want a higher return to compensate. So yields go up.

Why does the 5-year bond matter for my mortgage?

The 5-year bond is the benchmark lenders watch for 5-year fixed mortgages, a popular term in Canada. Money.ca notes that fixed rates follow the 5-year Government of Canada yield. Think of the yield as the lender's base cost, with the lender's margin added on top. When that base cost rises, the mortgage rate tends to follow.

Here's how much it has moved. The C.D. Howe Institute noted the 5-year yield was about 3.7% on September 30, versus under 1% when many 2020 and 2021 mortgages were signed, according to Canada News Media. The same piece put the 10-year yield at 3.99% and the 2-year at 3.37%.

Why are bond yields rising right now?

Bond yields are rising because markets expect higher interest rates and stickier inflation. Canadian inflation was 3.0% in August (Canada News Media), above the Bank's 2% target. US yields matter too. The C.D. Howe piece cited the US 10-year at 5.3%, and Canadian yields tend to move in the same direction as US yields.

Markets have also been pricing in Bank of Canada hikes. In September, The Globe and Mail reported that bond swaps priced a 0.25% hike by year end and a second in early 2027. Bond yields move on those expectations before the Bank acts.

What does this mean for buyers?

For buyers, higher fixed rates mean higher payments and a tougher stress test. Here's simple example math on a 25-year amortization, comparing an example rate of 4.50% with an example rate of 4.90% (a 0.40% jump). These are example rates, not a quote.

The stress test moves too. You have to qualify at the greater of your contract rate plus 2% or 5.25%. So at an example contract rate of 4.50%, you'd qualify at 6.50%. At 4.90%, you'd qualify at 6.90%. That can shrink your maximum budget.

What does this mean for renewers?

For renewers, it means the rate you see at renewal could be well above what you signed in 2020 or 2021. An RBC/Leger poll found 82% of homeowners renewing within two years worry about rate increases, according to bips. A CMHC survey from May 2026 found renewers saw payments rise an average of $375 a month (same source).

A few things in your favour:

1. Federally regulated lenders must send your renewal notice at least 21 days before your term ends, but you can start shopping well before that.
2. You can switch lenders at renewal. Since late 2024, uninsured straight switches don't require the stress test (Money.ca, citing OSFI).
3. Banks have been reaching out to renewing clients earlier (bips). Take the call, but compare before you sign.

My renewal page covers the full process. You can test different rates in the renewal calculator.

Why does a rate hold matter right now?

A rate hold matters because it protects you from further increases while you shop, buy or renew. Rate holds commonly last up to 120 days, according to The Canadian Wire. If rates keep rising, you keep the held rate. If rates fall before you close, you can usually ask for the lower one.

When fixed rates have moved 40 to 50 basis points on some terms since early September, a hold can make a real difference. On the $600,000 example above, 0.40% is about $135 a month.

Will the October 28 decision change fixed rates?

Maybe a little, but not directly. The Bank of Canada announces its next decision on Wednesday, October 28, and as of today nobody knows whether it will hike or hold. A hike that markets already expected might barely move bond yields. A surprise either way could. Fixed rates will keep following bonds, so watch yields, not just the headline.

What I'd do next

If you're buying or renewing in the next four months, I'd get a rate hold in place now, before the October 28 decision. Then I'd compare your current lender's renewal offer against a few others instead of signing the first letter. If you have a variable rate or HELOC, the October 28 decision matters more directly for you, and I'll post an update on my news page.
