The behavioral risk in this trade war is not on the Canadian side — it is on the American consumer side, and the data is already telling us how it ends. When discretionary prices rise 20%, roughly 20% of consumers stop purchasing. A 50% tariff does not get absorbed by importers or retailers. It gets passed to the end of the chain, where demand simply evaporates.
I want to separate the known from the unknown. We know the Dallas Fed found that the April 2025 tariffs added approximately 90 basis points to PCE inflation. We know the current Canada round affects only about 5% of $382 billion in bilateral trade. We know Canada's September 8 counter-tariffs target 700-plus US goods worth C$27.6 billion.
What we do not know is whether Trump follows through on the January doubling of auto and steel tariffs. If he does, the impact is not 5% of Canadian imports — it is the entire automotive supply chain, which cannot be reconfigured in a quarter.
The position sizing lesson is straightforward. Exposure to sectors with Canadian supply chain dependency — construction materials, automotive, steel, dairy, agricultural equipment — carries policy risk that cannot be hedged through normal portfolio construction. The tariff timeline is binary: either negotiations resume or escalation continues.
Carney's C$7.5 billion aid package signals Canada is prepared for duration. The US has no comparable consumer protection mechanism announced.
