Mortgage Rates Rise in October 2026: The Big Six Banks Move, the Bank of Canada Doesn't
Financing · October 8, 2026 · 5 min read
RBC, TD, CIBC and the other three big banks raised their posted mortgage rates in early October 2026 while the policy rate holds at 2.25%. Here is what the increase means for your renewal, your home purchase and your choice between fixed and variable.
You have probably seen the news this week: Canada's big banks are raising their posted mortgage rates. RBC kicked things off on October 6, with increases of 10 to 20 basis points on its 1- to 5-year fixed rates. Its posted 5-year fixed now sits at 5.14%. CIBC and TD had already moved the week before. In the end, all six big banks raised their posted rates within a few days.
Meanwhile, the Bank of Canada announced nothing. Its policy rate is still at 2.25%, and its next decision only comes on October 28. Rates going up while the central bank leaves everything alone: how is that possible? That is the question we answer here, with concrete numbers and what it changes for you.
What happened, in numbers
First, the facts. On October 6, RBC raised its posted mortgage rates: fixed terms from 1 to 5 years went up by 10 to 20 basis points, and the posted 5-year fixed moves to 5.14%. The variable rate is not spared either: the discount offered on the 5-year variable was cut by 20 basis points for new borrowers, which pushes the effective variable rate up as well.
RBC is not an isolated case. CIBC and TD had already raised their posted rates the week before, and with this latest move all six big Canadian banks have now acted. When everyone moves at the same time, it is never a coincidence: a single engine is pushing rates up.
That engine is the bond market. Banks fund their fixed-rate loans on bond markets, and Government of Canada bond yields have climbed in recent weeks. The 5-year bond was hovering around 3.58% on the morning of October 6, after peaking at 3.729% at the end of September. When the banks' funding costs rise, their posted rates follow. It is mechanical.
Why the Bank of Canada has nothing to do with it
This is the point that confuses everyone, and it deserves to be said plainly: the Bank of Canada's policy rate drives variable rates, not fixed rates. Fixed rates follow bond markets. These are two separate circuits feeding the same mortgage.
We have already broken down this mechanism in detail in our article on fixed rates and the policy rate. The key takeaway for this week: fixed rates can rise, or fall, while the policy rate does not budge an inch. That is exactly what just happened.
What it changes for you, in practice
Renewing your mortgage soon?
This is the case that weighs the most. About 1.15 million mortgages are coming up for renewal in Canada this year and next, the biggest renewal wave in the country's history. If you bought between 2020 and 2022 at a very low rate, the gap with today's rates remains huge, and every 20 basis points counts.
To give you a concrete idea: on a $500,000 balance amortized over 25 years, a 20-basis-point increase works out to about $56 more per month, or more than $670 a year. On a budget already squeezed by a renewal at a much higher rate than the original one, every dollar counts. If your renewal letter is arriving in the coming months, now is the time to compare offers instead of signing your bank's first proposal.
Looking to buy?
Higher posted rates also mean slightly lower borrowing capacity. Your file is qualified under the stress test with a qualifying rate that follows market rates: when rates go up, the amount you can borrow goes down. Before falling in love with a property, recalculate what you can actually finance at today's rates: the simulator applies the stress test exactly like your lender does.
Fixed or variable, right now?
That is the question everyone asks when fixed rates rise. Right now, the gap is still notable: the best insured rates are around 4.59% for a 5-year fixed and 3.45% for a 5-year variable. Variable is therefore still cheaper in the short term, but it will move with the Bank of Canada's next decision.
The October 28 decision hangs over the debate, with the October 19 inflation report just before it. Opinions are split: some observers see a policy rate hike as all but certain by year-end, while others expect the Bank to sit on its hands. Nobody knows, and that is normal. The right question is not to guess, but to know what your budget could handle in each scenario. Test both scenarios in the refinancing simulator of the Analysis module: change the rate, and you instantly see the effect on your payment.
Track rates live instead of reacting to the news
The problem with increases like this week's is that you hear about them after the fact, in the news. Yet the data moves every day. Hom24 shows live rates, updated daily, and the Analysis module shows you today's rate with an alert when it drifts from your scenario. When the market moves, you see it in your analysis before you read it in the headlines.
And if you are a broker, this week hands you a perfect conversation starter with your clients. A market bulletin that explains the increase in plain language, generated from real-time data, is worth more than a long speech. The Hom24 CRM prepares it for you, ready to share.
In summary
The six big banks raised their posted mortgage rates in early October, led by RBC with a 5-year fixed at 5.14%. The engine behind the increase is bond yields, not the policy rate, which holds at 2.25%. For you, that means: compare offers if you are renewing soon, recalculate your capacity if you are buying, and test both scenarios, fixed and variable, before deciding. Rates are moving fast right now; track them live rather than react to them.
