Canada PM: Tariff Measures Against US Effective Sept 8

This is a tit-for-tat escalation between two of the world's largest trading partners, and the fact that a fixed effective date was named gives markets a countdown rather than an open-ended threat. Steel and aluminum are inputs into autos, construction and machinery, so the pressure runs through industrial supply chains rather than crypto or RWA markets directly. The open question is whether this stays a contained, sector-specific exchange or becomes the first step in a broader tariff cycle, since that distinction is what would move risk sentiment.
