The Bank of Canada's (BoC) monetary policy calculations have recently become very complicated. Major macroeconomic variables, including the gap in economic strength with the U.S., defending the currency, and CUSMA uncertainty, are intertwining and having a direct impact on Canadian fixed mortgage rates.

Key Points

• Diverging economic strength: Unlike the U.S., which is growing on the back of solid employment and consumer spending, Canada faces a much greater need for policy rate cuts due to high household debt and a slowing economy.
• Limits of rate synchronization: The Government of Canada 5-year bond yield (the benchmark for fixed rates) is heavily tied to U.S. long-term bond trends. If the BoC cuts rates sharply on its own, the interest rate gap with the U.S. (Interest Rate Differential) widens, triggering capital outflows and a weaker Canadian dollar (CAD).
• A weaker dollar and imported inflation: When the Canadian dollar falls, the prices of goods imported from the U.S. rise, creating the risk of 'rising import prices' that could reignite domestic inflation that was brought under control with great difficulty.
• CUSMA risk premium: Recent U.S. refusal to renew CUSMA and threats of tariffs have sent the 'currency risk premium' on the Canadian dollar soaring. This is acting as a powerful negative that drags the exchange rate down regardless of the rate gap.
• The weakened petro-currency formula: Traditionally, higher international oil prices led to a stronger Canadian dollar, but recently, weighed down by global trade uncertainty and a strong U.S. dollar, rising oil prices have offered only limited support for the currency.

What It Means

Looking only at Canada's domestic economy, rates should be cut aggressively right away, but the central bank's hands are tied by the risk of a plunging dollar from the rate gap with the U.S., renewed inflation, and tariff uncertainty. In particular, because fixed mortgage rates move in line with U.S. government bond yields, they are likely to stay tightly held at high levels for the time being, despite weak domestic demand in Canada.

At a time like this, when global macro variables are shaking up the mortgage market, it is best to let go of vague hopes of rate cuts. If you have a renewal or home purchase ahead, we recommend getting an approval in advance to lock in your rate in preparation for the impact that currency and trade risks could have on rates, and making a conservative financing plan.
