Why does a Strait of Hormuz blockade matter for Canada?

How could the Trump Iran ultimatum move markets this week?

Keep a cash buffer, avoid leverage, and right-size position sizes for wider swings. Balance equity with quality bonds, consider some energy exposure, and use USD assets to cushion CAD moves. Write a rules-based plan with add and reduce triggers to stay disciplined during headlines.
