The recent global oil price shock has introduced a complex set of variables for Canadian monetary policy with direct implications for housing affordability. As oil prices surged above US$100 per barrel in early 2026, the Bank of Canada (BoC) maintained its policy interest rate at 2.25 per cent during its March 18 meeting. While Governor Macklem indicated a “look through” approach to the immediate energy price spike, the bond market responded with far less patience, creating a divergence that risks increasing the financial strain on Canadian households.
Strategic Policy Framework for Supply Shocks
Bank of Canada Deputy Governor Sharon Kozicki’s March 2 speech in Oslo, “Monetary Policy in a Turbulent World,” provided the intellectual framework for this decision, articulating a strategy for navigating supply-driven trade-offs when inflation and economic growth move in opposite directions:
- Flexible inflation targeting remains the goal, but the Bank must contend with more frequent and persistent supply disturbances.
- When a shock is expected to have large or lasting impacts, some policy restraint is warranted, even if the broader economy is weak.
- For housing, this means rate cuts are unlikely if easing risks allowing energy-driven inflation to become entrenched.
Bond Market Volatility and Mortgage Rates
The most immediate impact on housing has come from the bond market. Following the oil shock, Canadian five-year bond yields surged as investors priced in higher long-term inflation risks, prompting major lenders to raise fixed mortgage rates. For the millions of Canadians facing mortgage renewals in 2026, these market-driven increases translate into an erosion of affordability.
Bond Markets and Iran Conflict Uncertainty
Bond markets are sensitive to geopolitical uncertainty, and the ongoing Iran conflict presents an unusually wide distribution of possible outcomes for investors. As traders grapple with the risk of prolonged disruption to energy supplies and inflation pressures, markets have tended to adopt a risk-off approach, pricing in a heightened risk premium. This dynamic has contributed to volatility in government bond yields, with the five-year Government of Canada bond market largely echoing swings in the U.S. Treasury market as investors reassess expectations around inflation, risk sentiment, and global growth in response to geopolitical headlines.
Implications for Borrowers
Where bond traders reprice risk within minutes, the BoC operates at a more measured pace. The Kozicki framework makes this explicit: when a shock is clearly supply-driven and second-round inflation expectations remain anchored, a credible central bank can afford to wait before adjusting the policy rate.
This divergence leaves Canadian borrowers in a difficult position. The BoC’s measured pause offers no relief for variable rates tied to the overnight rate, while bond markets independently drive fixed rates higher. As a result, households face rising borrowing costs on both fronts simultaneously, with little practical comfort from a central bank whose patience may be intellectually defensible but financially irrelevant for a family facing mortgage renewal in 2026.
Conclusion
As recent rate movements suggest, a political off-ramp could lead to lower bond rates as inflationary and geopolitical pressures ease. However, oil prices are unlikely to fully return to levels seen at the beginning of the year.
