Bank of Canada Governor Tiff Macklem has warned that new US tariffs could sharply slow Canada’s economy, with fourth-quarter growth potentially falling to below 1%. The estimate points to a material hit to activity at a time when policymakers are already navigating a fragile balance between weak growth and stubborn price risks.
The warning matters because the central bank is facing two shocks at once: trade barriers that threaten demand and higher oil-linked fuel costs that can lift inflation. Macklem signaled that officials do not want to overreact to an energy-driven price spike if broader inflation remains contained.
For investors, the message is clear: Canadian monetary policy may stay cautious even if headline inflation rises in the near term, because the Bank of Canada is focused on whether price pressures spread beyond energy while growth weakens under tariff pressure.
Key Facts
- The Bank of Canada said new US tariffs could roughly halve fourth-quarter growth to below 1%.
- Macklem said inflation would likely edge higher in coming months if oil prices remain near $100 a barrel.
- Recent gasoline prices have behaved as if oil were almost $40 a barrel higher than prevailing crude levels.
- The Bank of Canada has not yet seen evidence that higher oil prices are spreading broadly into other goods and services.
- The central bank expects labor force growth to be close to zero over the next few years.
Bank of Canada and US Tariffs
The central issue for the Bank of Canada is that US tariffs could weaken Canadian output just as energy costs lift consumer prices. Canada’s economy is highly exposed to cross-border trade, so new tariffs can quickly affect exports, investment plans, business sentiment and hiring. A fourth-quarter growth rate below 1% would mark a notable loss of momentum for an economy already adjusting to slower population-driven labor supply growth.
Macklem’s comments suggest policymakers are trying to distinguish between a temporary inflation shock and a more dangerous, persistent one. If higher oil and gasoline prices remain concentrated in fuel, the central bank may be willing to look through that move rather than tighten policy into a slowing economy. But if transportation, food, services or wage expectations begin to reflect sustained energy costs, the policy debate becomes more difficult.
That distinction matters for households, exporters, rate-sensitive sectors and currency markets. Consumers face higher fuel bills, businesses face trade uncertainty, and borrowers are watching whether the Bank keeps rates steady or turns more hawkish. At the same time, evidence that many Canadian businesses have started adapting to US tariffs suggests the damage may not be uniform across industries, with larger and more diversified firms potentially better positioned than smaller exporters.
“The Bank of Canada is signaling that weak growth from US tariffs may outweigh a temporary oil-price inflation shock unless broader price pressures start to spread.”
Why energy prices complicate the policy outlook
Macklem highlighted an unusual gap between crude oil and retail fuel behavior, noting that gasoline prices have risen more than would normally be expected because of damage to global refining capacity. In practice, that means consumers can feel a sharper inflation hit even when benchmark crude prices alone do not fully explain it.
For central bankers, refinery disruptions are especially difficult because they can push headline inflation higher without necessarily indicating stronger underlying demand. That is one reason the Bank of Canada appears reluctant to raise rates simply to counter an oil-driven move if core inflation dynamics remain stable.
Implications for Investors
For bond investors, Macklem’s comments lean dovish on growth but cautious on inflation. If tariffs drag Canadian activity below trend, expectations for aggressive rate hikes may fade. However, any sign that higher energy costs are feeding into core inflation could quickly revive concerns about a firmer policy response. That leaves Canadian yields sensitive to both trade headlines and inflation data in the months ahead.
For equity investors, the biggest divide may be sector-specific. Export-oriented manufacturers and firms with heavy US exposure could face margin pressure and slower demand if tariffs remain in place. Energy producers may benefit from stronger crude prices, but that support can be offset elsewhere in the market by weaker consumer spending and softer domestic growth. Financials and real estate could also remain vulnerable if slower growth weighs on credit demand and household confidence.
In currency markets, the Canadian dollar is likely to be pulled in opposite directions. Higher oil prices can support the loonie, while weaker growth and a more patient Bank of Canada can undermine it. Traders will be watching whether tariff risks escalate, whether inflation broadens beyond fuel, and whether labor market softness reinforces the Bank’s concern about a lower-growth economy.
The next phase for markets will depend on how long US tariffs stay in place and whether energy-driven inflation remains contained. If trade barriers persist while price pressures broaden, the Bank of Canada may face a far narrower path between supporting growth and defending price stability.
