Bank of Canada Governor Tiff Macklem warns 'consecutive' rate hikes are possible — what that means for Canadian mortgage holders

In the BoC’s Monetary Report released in April 2026, Governor Macklem warned that ongoing elevated oil prices and energy costs could feed into broader inflation, forcing the BoC to deliver consecutive rate hikes.

Now the next rate announcement, scheduled for July 15, sits in the shadow of that warning — and the inflation data since April has not made the outlook simpler.

In these uncertain times, here’s what homeowners and home buyers need to understand about rate risk, how it could affect their borrowing costs, and what steps are worth taking, right now.

Why ‘looking through’ inflation has limits

Central banks routinely ‘look through’ temporary price spikes caused by supply shocks — energy disruptions, weather events, one-off tax changes. The logic behind this approach is straightforward: Raising rates to fight a gas price spike that will likely reverse on its own would cause unnecessary economic pain.

The Bank of Canada applied exactly that logic in early 2026 when the Iran war and closure of the Strait of Hormuz sent global oil prices soaring. As a result, the BoC’s April Monetary Policy Report (MPR) assumed crude would ease from around US$100 per barrel to US$75 by mid-2027, projecting that inflation would peak around 3% in April before cooling toward the 2% target by early next year.

But Macklem was explicit about where that tolerance ends. The risk, he said, is that elevated energy costs begin spreading into wages, services and other goods — becoming what economists call ‘second-round effects.’

If those ‘second-round effects’ are triggered, the BoC cannot simply stand by and watch.

Statistics Canada confirmed in May that headline inflation rose to 2.8% year over year in April 2026 — up from 2.4% in March — with gasoline prices 28.6% higher than a year earlier. Crucially, core inflation — which strips out volatile components like gas — came in at 2.1% and was actually softer than in March. Why does this matter? Because right now it shows that soaring energy costs have not yet spread — the ‘second-round effects’ have not been triggered. But the Bank has made it clear: They are watching closely for any sign, and if it does, they will respond. More than likely, that response will come as a rate hike.

What consecutive rate hikes would do to a $500,000 variable mortgage

The BoC policy rate currently sits at 2.25%, which puts most lenders’ prime rate at around 4.45%. Variable-rate mortgage holders end up paying prime plus or minus the lender rate. For most borrowers, this means a variable-rate mortgage of prime minus the discounted range, which is currently between 0.5% to 1.0%.

But fast-forward to a point in time after two consecutive 25-basis-point BoC rate hikes — the scenario Governor Macklem described — and the BoC policy rate now sits at 2.75% — shifting your lender’s prime rate to roughly 4.95%. On a $500,000 variable mortgage with a 25-year amortization, that shift translates to approximately $130 to $150 more per month in interest costs (depending on the specific rate and payment structure).

Fixed-rate borrowers face a different but related pressure. Fixed mortgage rates are priced off Government of Canada bond yields, not the overnight rate. But fixed income markets will adjust pricing based on expectations — including a modest probability of rate hikes. When this happens, bond yields rise, and fixed rates follow. As a result, borrowers renewing fixed mortgages in the next 12 months are looking at potentially higher mortgage rates — at a time when they are already renewing into rates well above what they originally locked in.

For context, the market assumed a 5% probability of a rate hike on June 10 and about an 7% chance of a rate hike on July 15 — low odds, but a material shift from the near-zero probability that prevailed just a few months ago.

The Middle East conflict as a Canadian personal finance risk

The Iran war and the Strait of Hormuz closure account for roughly 20% of global oil supply. Macklem told the Senate committee that the conflict has pushed global energy prices sharply higher, increased financial market volatility and disrupted shipping for fertilizer and other commodities — all of which weigh on the global growth outlook.

For Canadian households, these economic headwinds have a direct impact both on Canadian budgets and on economic growth. For instance, the price of gasoline is up 28.6% year over year — a direct cost that’s felt at the pump every day. Even those that don’t drive are feeling the impact, with food suppliers adding fuel surcharges that eventually work their way through to grocery prices. And it’s not just gas. Utility costs — water, fuel and electricity — rose 5.5% year over year in April, according to Statistics Canada, reflecting higher energy input costs, all around.

The Bank of Canada’s MPR notes a second, countervailing risk as well: Significant new U.S. trade restrictions on Canada. The Canada-U.S.-Mexico Agreement (CUSMA) comes up for review in July and any hiccup or headwind in this agreement could slow Canadian economic growth enough to require rate cuts rather than hikes.

Unfortunately, the forces impacting Canada’s economic outlook require action in opposite directions, which is precisely why Macklem has avoided giving a clear directional signal and instead described the path ahead as “unusually uncertain.”

How to rate-proof your budget

None of this means Canadians should panic — or rush into a fixed rate at the first sign of concern. But there are specific steps worth taking before the July 15 BoC rate announcement or the remaining 2026 rate decisions (when the Bank should have significantly more inflation data).
