Canada Fixed Mortgage Rates Increase as Middle East Oil Shock Hits Borrowers

Canada fixed mortgage rates increase as lenders move pricing higher in step with the latest oil shock. Canadian lenders have raised fixed mortgage offers significantly since mid-March, while bond yields stay elevated in the wake of the continuing war in Iran. Borrowers watching the market now face a sharper choice between locking in and shifting to variable terms.

Canada fixed mortgage rates increase as lenders reset pricing

Canadian lenders have added between 30 and 40 basis points to discounted and posted fixed mortgage offers since mid-March. The lowest insured five-year fixed mortgage rate on Ratehub. ca has climbed to 4. 09 per cent from 3. 79 per cent at the start of March.

For a borrower with a $500, 000 mortgage, that change means about $80 more each month and $7, 064 more in total interest over a five-year term. The move comes as bond investors sell holdings and lenders face a higher pricing floor for fixed borrowing products.

Canada fixed mortgage rates increase further when five-year Government of Canada bond yields stay elevated, and that has been the pattern since March 18. The five-year yield remained above 3. 1 per cent through much of that stretch, briefly dipping to 3. 08 per cent on Thursday.

Why borrowers are looking at variable rates

As fixed borrowing gets more expensive, some borrowers are turning toward variable-rate options. The lowest five-year variable rate sits at 3. 35 per cent, creating a 74-basis-point gap between the two rate types, a spread not seen since the fall of 2022.

That gap is already changing borrower behavior. By the end of March, variable deals made up more than 30 per cent of all deals on Ratehub, up from 19 per cent at the end of December last year.

For a borrower comparing today’s lowest rates, a mortgage at 3. 35 per cent would save $196 a month versus locking in at 4. 09 per cent. Still, the risk remains that floating-rate borrowers could face higher costs if inflation broadens beyond energy.

Market pressure is tied to oil and inflation fears

The immediate trigger is the surge in oil prices linked to the continuing war in Iran. Bond investors have been selling as they weigh the chance that higher energy costs could reheat inflation and erase the possibility of central bank rate cuts in 2026.

The five-year Government of Canada bond yield is central to pricing for five-year fixed mortgage terms, and lenders appear to be using that signal to adjust rates quickly. Some providers are still keeping default insured rates near four per cent, but the broader direction has been higher.

What lenders and policymakers are watching next

Market pressure is likely to persist as long as the war in Iran continues and the Strait of Hormuz remains closed. Contradictory comments from U. S. President Donald Trump have not eased concerns, with yields rising alongside fears that the conflict could drag on.

The Bank of Canada’s governing council said in a summary of deliberations published on April 1 that it is “too early” to react to war-induced energy spikes. For now, Canada fixed mortgage rates increase alongside oil and bond moves, leaving borrowers to decide whether today’s spread justifies the added risk of a variable loan.
