Why Does the Price of Oil Move USD/CAD and the Canadian Dollar?
Direct answer
Oil and the loonie
Oil moves the Canadian dollar because crude is one of Canada's largest exports: higher prices bring more US dollars into Canada, improve its trade balance and growth outlook, and tend to strengthen the loonie, which means USD/CAD falls. In Federal Reserve and EIA data, the daily correlation between USD/CAD and WTI crude was −0.60 in 2010 and around −0.3 to −0.5 in most years to 2023. The link weakened to −0.15 in 2024 and was about +0.1 in 2025 and 0.0 in 2026, as interest-rate gaps, trade policy and supply-driven oil shocks dominated.
- Canada exports large amounts of crude, mostly to the US
- Normal pattern: oil up → Canadian dollar up → USD/CAD down (negative correlation)
- Daily correlation: −0.60 in 2010, −0.37 in 2021, −0.15 in 2024, about 0 in 2025–26
- Rates, trade policy and supply-driven oil shocks can break the link
The Canadian dollar is often called a "petrocurrency". That label is based on a real relationship, but the numbers show it is far from fixed.
What people on X are asking
In August 2025 a futures-exchange account asked why the Canadian dollar was gaining strength even as oil prices declined, pointing to weak US job growth instead. In March 2026 a post asked what $100 oil would mean for Canada, quoting a strategist who said the loonie was "recoupling" to oil. In May 2026 an analytics account asked whether the Canadian dollar is still a petrocurrency, arguing the link was weaker than ever. Our data let us check.

Why the link exists. The EIA reports that Canada is the largest single source of US crude oil imports; in 2022 it supplied 60% of gross US crude imports. When oil prices rise, Canadian exporters earn more US dollars and sell them for Canadian dollars, the trade balance improves, and energy investment and government revenue rise. Investors anticipate this, so the Canadian dollar tends to strengthen. Because USD/CAD is quoted as Canadian dollars per US dollar, a stronger loonie shows up as a falling USD/CAD, hence the negative correlation.
How strong it has been. Using daily changes and excluding the negative April 2020 price, we calculated the correlation for each calendar year:

Why the link weakened. Several forces can overpower oil. First, interest-rate differences: if the Fed holds rates higher than the Bank of Canada, money flows to the US dollar regardless of oil. Second, trade policy: tariffs and uncertainty about access to the US market affect Canada's whole economy, not just energy. Third, the type of oil shock: when oil jumps because of a supply disruption or war, it often comes with global risk aversion that lifts the US dollar too, cancelling the usual effect. WTI went from about $56 in early January 2026 to about $115 in April, yet USD/CAD stayed between about 1.35 and 1.43 all year, which matches the near-zero correlation.
What still holds. Over long periods, Canada's terms of trade still matter. A sustained fall in oil, like 2014–15, has historically come with a much weaker Canadian dollar: USD/CAD rose from about 1.17 at its 2015 low to almost 1.40 within the year in Federal Reserve data. Short-term traders should treat oil as one input, not a reliable signal.
Practical uses. If you trade USD/CAD, watch weekly US crude inventory reports, OPEC decisions (see what moves oil prices), Bank of Canada and Fed decisions, and Canadian jobs data. If you hold both oil and Canadian dollar positions, check whether they are really diversifying each other; see correlation in trading.

Decision helper
| Situation | Likely effect on USD/CAD |
|---|---|
| Demand-driven oil rally, calm markets | Down (stronger loonie) |
| Supply-shock oil spike with risk-off mood | Mixed; dollar strength can dominate |
| Bank of Canada cuts more than the Fed | Up |
| Trade-policy shock to Canada | Up |
Common mistakes
- Assuming oil always moves the loonie; in 2025–26 it barely did.
- Forgetting that USD/CAD falls when the Canadian dollar strengthens.
- Ignoring interest-rate gaps between the two central banks.
- Treating a correlation from one year as a trading rule.
FAQ

It has usually gone down, because the Canadian dollar strengthens.
Is the Canadian dollar still a petrocurrency?
The link was weak in 2024 and close to zero in 2025–26 in daily data.
What else moves the Canadian dollar?
Bank of Canada versus Fed rate expectations, trade policy, jobs data and global risk appetite.
What is the Bank of Canada's role?
It sets Canadian interest rates and publishes daily exchange rates.
Which oil price matters for the loonie?
