Bank of Canada Sees Inflation Above 3% Through Much of 2027, a Warning for Owners Renewing Fixed Mortgages

A 2027 That Was Supposed to Be at Target Is Now the Hot Year

The revision is not subtle. In July, the Bank expected inflation to be back at target in 2027. In October, it expects 2027 to be the year inflation runs highest. According to the Bank's October projection tables, CPI inflation is now forecast to average 3.1% in 2027, up from 2.0% in the July Report, after averaging 2.9% in 2026 against July's 2.5%.

The quarterly path gives the shape. Year-over-year inflation was 3.0% in the third quarter of 2026 and is projected at 3.4% by the fourth quarter, then to keep rising into the first quarter of 2027. The Bank's outlook keeps it above 3% through the third quarter of 2027, easing to 2.6% by the end of that year and 2.1% by the end of 2028.

The Bank attributes the revision mainly to cost pressure from abroad: oil prices and refinery margins that are expected to stay high for longer because of conflicts overseas, higher prices for imported inputs, and Canadian counter-tariffs. A temporary offset — the suspension of the federal fuel excise tax — runs out in April 2027, which is one reason the forecast keeps inflation elevated well into next year. This is cost-push inflation, not an overheating domestic economy. That distinction matters later, because cost-push episodes are exactly the kind central banks worry will spread.

For context on where the big banks' rate calls sat before today, Homeowner.ca covered RBC's expectation of a full point of Bank of Canada hikes in 2027.

The Overnight Rate Moves Variable Rates; Bond Yields Move Fixed Rates

Two different interest rates drive Canadian mortgages, and they are easy to conflate. The overnight rate, which the Bank raised today, flows through lenders' prime rates within a day and reprices variable-rate mortgages and lines of credit almost immediately. A fixed rate works differently. A lender funding a five-year mortgage is effectively borrowing for five years, so it prices that mortgage off what five-year money costs in the market — the yield on Government of Canada bonds of a similar term — plus a margin.

The Bank of Canada uses exactly that logic in its own research. In a 2025 analysis of renewal payments, Bank of Canada staff modelled a fixed-rate borrower's renewal rate as a spread of 150 basis points above the forecast Government of Canada bond yield. The overnight rate does not appear in that formula. That is the central bank telling you where to look.

The chain from today's report to your renewal offer runs in five links:

• Inflation outlook. The Bank now expects inflation above 3% through much of 2027.
• Expected policy path. Markets infer that the Bank will need a higher policy rate for longer to bring that down.
• Term premium. Investors demand extra compensation to lend for five or ten years when the path is uncertain.
• Bond yield. The five-year Government of Canada yield absorbs both of the above.
• Your fixed rate. Lenders typically add a margin of roughly one to two percentage points above the bond yield, according to nesto's rate tracker, which reported the five-year yield at 3.54% on Oct. 16 after a 52-week high of 3.729% on Sept. 28.

A quarter-point move in the overnight rate can nudge the second link. It does not, on its own, decide the fifth. Fixed rates can rise when the Bank holds, and fall when it hikes, if the bond market has already moved on.

What the Report's Bond-Yield Section Says

The Bank's In Focus on the rise in long-term sovereign bond yields says yields have been rising since 2021 and accelerated in 2026, reaching their highest levels in more than a decade across many advanced economies. Its explanation splits the increase into two parts. One is expectations of higher policy rates, driven by persistently elevated energy prices; the Bank says this accounts for the majority of the rise in Canada, the United States and Germany. The other is the term premium, which the Bank ties to heavier government and corporate borrowing — including debt issued to fund artificial-intelligence infrastructure — and to rising uncertainty about how restrictive monetary policy will need to be. The Bank also cautions that these splits are model estimates, indicative rather than definitive.

Read that through a renewal lens. The largest driver of higher yields in Canada is the market's expectation of a higher policy path. Today's report, by raising the inflation forecast for 2027, gives the market more reason to hold that expectation, not less.

Lenders had already acted on it. On Sept. 29, CIBC and TD raised several fixed rates by 20 basis points, mostly on three- and five-year terms, while other lenders moved by five to 40 basis points as the five-year yield touched its 52-week high, Canadian Mortgage Trends reported. By early October, some terms at the big banks were up by as much as half a percentage point in roughly five weeks. All of that happened while the Bank of Canada was still holding at 2.25%.

RBC Economics made the same point in mid-October: the overnight rate matters most for variable mortgages and consumer credit, while rising term yields were already reshaping fixed-rate borrowing. Its economists also identified the group most exposed — a final cohort of five-year fixed borrowers who locked in ultra-low rates in 2021 and 2022 and have yet to renew.
