When crude oil prices slide, you typically see ripple effects across commodity-linked currencies—and the Canadian dollar is living proof. It just posted its longest losing streak in 10 months as oil continues to weaken.

Commodity currencies tend to move in tandem with energy prices, so watching CAD weakness can actually be a useful barometer for where risk appetite is heading across global markets.
