Sources Table of Contents Let's fix the biggest misconception first: fixed mortgage rates in Canada are not set directly by inflation. Fixed rates are driven mainly by Government of Canada bond yields, plus the lender's spread for funding costs, credit risk, servicing, and profit margin. Variable rates are a different mechanism: they move with prime, which is tied closely to the Bank of Canada's policy rate. How Fixed Mortgage Rates Are Actually Priced When lenders price a 3-year or 5-year fixed mortgage, they look first at the matching part of the bond market — especially Government of Canada bond yields. If those yields rise, fixed mortgage pricing usually rises. If those yields fall, fixed pricing often improves. That means fixed rates can move even when the Bank of Canada does nothing. The bond market moves first, and mortgage pricing often follows. Why Inflation Still Matters — Indirectly Inflation matters because it can change what bond traders expect for future interest rates, economic growth, and risk. But the chain is indirect: New inflation data changes market expectations Those expectations move Government of Canada bond yields Lenders reprice fixed mortgages off those yields So saying "fixed rates moved because of inflation" is incomplete. More accurately: fixed rates moved because bond yields moved, and inflation was one of the reasons yields moved. What the March 2026 Headlines Actually Changed The Bank of Canada held its policy rate at 2.25% in March 2026. In that same communication, the Bank said the war in the Middle East had increased volatility in global energy prices and financial markets and that the economic effects were still uncertain. Lock In Today's Rates Mortgage rates change daily. Get a rate hold for up to 120 days and protect yourself from increases. Get Rate Quote That matters because geopolitical shocks do two things at once: they can raise near-term inflation anxiety through oil prices, and they can also push bond markets around as traders reprice risk. That's why fixed mortgage rates can move sharply even before the Bank of Canada changes the overnight rate. Why Variable Rates Behave Differently Variable mortgages do not price off bond yields the same way fixed mortgages do. They are tied to a lender's prime rate, which usually moves after Bank of Canada rate decisions. Lenders can still change discounts, but the main driver is monetary policy, not the Government of Canada bond market. That's why borrowers often see this disconnect: the Bank of Canada holds or cuts, but fixed rates stay high because bond yields remain elevated or bond yields fall first, and fixed rates improve before the Bank of Canada actually cuts What Borrowers Should Watch Right Now For fixed rates: watch Government of Canada bond yields For variable rates: watch the Bank of Canada and prime rate expectations For timing: remember the two products do not react on the same schedule If you're choosing between fixed and variable, inflation forecasts are only one piece of the puzzle. Compare where bond yields are heading, what markets expect from the Bank of Canada, and how much payment certainty you are willing to pay for—then stress-test those assumptions with real numbers. Run the numbers in our Fixed vs Variable Calculator → Bottom Line Inflation can influence mortgage pricing, but it is not the direct pricing mechanism for fixed mortgages. Bond yields drive fixed rates. Prime and Bank of Canada policy drive variable rates. If you understand that split, the market makes a lot more sense — especially during noisy periods like an oil shock or a hot CPI headline.

No. Fixed rates are priced mainly off Government of Canada bond yields for a similar term, plus the lender's funding spread, credit and operational costs, and margin. CPI and other inflation releases matter because they can shift rate expectations and risk appetite in the bond market, which then moves yields. What is the difference between what moves fixed mortgage rates and variable mortgage rates? Fixed mortgages track the bond market (especially GoC yields) for the matching tenor. Variable mortgages are tied to a lender's prime rate, which typically follows the Bank of Canada's policy interest rate. That is why fixed and variable pricing can diverge for weeks or months. Can fixed mortgage rates move even if the Bank of Canada leaves its policy rate unchanged? Yes. Bond yields react to new data, global risk events, and expectations about future inflation and growth. If yields rise or fall, lenders often reprice fixed mortgages even when the overnight target has not moved. March 2026 commentary from the Bank of Canada noted heightened volatility in energy prices and financial markets tied to conflict in the Middle East—conditions that can feed straight into bond-market repricing. How do oil shocks or geopolitical risk affect Canadian mortgage rates? They usually work through two channels at once: higher and more volatile energy prices can lift near-term inflation concerns, while uncertainty can change how investors price government bonds and credit risk. Either channel can move yields; for fixed borrowers, the bond channel is the one that hits quoted rates fastest. Why might fixed mortgage rates stay elevated after the Bank of Canada cuts? If Government of Canada bond yields remain high—because markets expect inflation to linger, term premia to rise, or fiscal and global risks to persist—lenders still face higher hedged funding costs for fixed-rate mortgages. A lower policy rate helps variable borrowers sooner; fixed borrowers need yields to cooperate too. What should I watch if I am deciding between a fixed and a variable mortgage right now? Watch GoC bond yields for the term you are considering, Bank of Canada guidance and forecasts for the policy path, and your own budget for payment swings. Our Fixed vs Variable Calculator can translate those views into monthly payment scenarios.
