The loonie explained
The Canadian dollar — nicknamed "the loonie" after the loon bird on the one-dollar coin — is one of the most reliable commodity currencies in the world. When oil prices go up, the loonie strengthens. When oil crashes, the loonie falls. The correlation is not perfect but it is strong enough that FX traders sometimes call CAD/USD a "petrodollar proxy."
The reason is mechanical: Canada exports a lot of oil and gas, especially to the US. When oil prices rise, more dollars flow into Canada (paid for Canadian oil), those dollars get converted into Canadian dollars, and that conversion pressure pushes CAD higher. When oil drops, the reverse happens. Over the last 20 years, CAD/USD has tracked oil prices closely enough that you can often guess one from the other.
The typical range
CAD/USD has spent most of the last two decades between 0.70 and 1.05. The peak was in 2007-2011, when oil was high and the US was in crisis — the loonie briefly traded above parity (1 CAD = 1 USD), which was a first in decades. Since then it has drifted lower and settled into a range of about 0.72 to 0.80. That range has been remarkably stable, punctuated by occasional drops when oil crashes (2014-2015, briefly in 2020).
What actually moves CAD/USD
- Oil prices. The single biggest driver. A sustained $10 move in WTI crude typically moves CAD/USD by a few cents.
- Bank of Canada vs Fed rates. When the BoC keeps rates above or below the Fed, the rate differential pushes the loonie up or down.
- US economic data. Canada's economy is so tied to the US that strong US data is usually good for the loonie too — more US growth means more Canadian exports to the US.
- Commodity prices broadly. Lumber, metals, wheat — Canada exports enough of all of them that broad commodity strength lifts the loonie.
For cross-border shoppers and snowbirds
Canadian snowbirds — retirees who spend winters in Florida, Arizona, or Mexico — watch CAD/USD obsessively. When the loonie is at 0.80, a $100,000 winter home in Arizona costs C$125,000. When it drops to 0.70, the same home costs C$143,000. That is a C$18,000 difference on the same property, caused entirely by the exchange rate. Many Canadians time their US property purchases around the loonie's cycles.
The same math applies to cross-border shoppers in cities like Vancouver, Toronto, and Montreal who drive across the border for cheaper US goods. At 0.80, US prices look reasonable. At 0.70, US shopping becomes expensive enough that the gas and time are not worth it. The border trade volume between Canada and the US genuinely ebbs and flows with the exchange rate.
Reading the chart
The CAD/USD 5-year sparkline should look roughly like an inverted oil price chart. Where oil has spiked, CAD has risen. Where oil has fallen, CAD has followed it down. If the current rate is significantly different from the 5-year average, check what oil has done recently — chances are the two match up.
