USDCAD Correlation in October 2026: Oil Near $108, and Why the Loonie Is Not Following

Oil near $108, USDCAD flat

Canada is a large oil exporter, so traders often treat the Canadian dollar as an oil currency: crude up, loonie up, USDCAD down. Over the last year the numbers tell a different story.

WTI figures are the daily Cushing spot price from the St. Louis Fed FRED series DCOILWTICO. USDCAD comes from ECB euro reference rates loaded through the Frankfurter exchange rate API and converted to a dollar pair, the same source the SIWAI correlation tool uses. In three months USDCAD stayed between 1.3740 and 1.4262, while WTI swung between $76.78 and $110.01.

USDCAD correlation readings in October 2026

The table shows the correlation coefficient of daily percentage returns between USDCAD and each market, for windows ending October 21, 2026. A reading of +1 means the two always move together, -1 means they always move opposite and 0 means no linear link.

What the table says:

• USDCAD is trading as a US dollar pair. Its strongest links are with the other dollar pairs, led by NZDUSD at -0.69 over three months. The minus sign only means the dollar sits on opposite sides of the two quotes. Over those three months USDCAD and NZDUSD closed in opposite directions on 50 of 66 days. See the NZDUSD vs USDCAD page and USDCAD vs USDCHF page.
• The oil link is close to zero. USDCAD against WTI daily returns reads -0.14 over three months and 0.02 over one year. The sign is the textbook one on short windows, but the size is too small to trade on.
• Big oil days were a coin flip. In the last three months WTI rose more than 2% on 17 days, and USDCAD fell on only 9 of them. On the 14 days WTI fell more than 2%, USDCAD rose on 11.

One honest caveat: ECB reference rates are fixed in the European afternoon (published around 16:00 CET, see the ECB reference rates page), while the WTI spot price is a US close. That timing gap weakens any daily FX and oil correlation a little. It does not explain a year where oil gained 85% and USDCAD finished flat.

Why the oil link has faded

USDCAD has two legs. The Canadian leg carries oil, Canadian data and the Bank of Canada. The US leg carries the Federal Reserve and the broad dollar. When the dollar is the bigger story, the US leg drowns out the oil leg, and USDCAD lines up with EURUSD, GBPUSD and NZDUSD instead of crude.

The rolling numbers show the link coming and going. Measured on rolling three month windows, the USDCAD and WTI correlation was -0.27 in mid February 2026, turned positive at 0.35 in May 2026 (the opposite of the textbook) and was back near -0.11 by mid October 2026. A link that flips sign within a few months is not a rule you can build a trade on. It is a reading you check.

For a dollar read on oil itself, compare crude with the dollar index on the DXY vs WTI correlation page. The full method for reading these numbers is in the guide to using correlation in forex.

What to watch: the Bank of Canada on October 28

The Bank of Canada's next interest rate announcement and Monetary Policy Report is on Wednesday, October 28, 2026 at 09:45 ET. Its policy rate page shows the target at 2.25%, unchanged at every 2026 decision so far, including September 2. The only other scheduled decision this year is December 9.

A rate decision is a Canadian leg event. It is one of the few days when USDCAD can move on its own and break away from the other dollar pairs. That makes it the day the correlation table above is least reliable, so do not assume a USDCAD position is hedged or doubled by a NZDUSD or USDCHF position into the announcement.

Holding USDCAD with other dollar pairs

Because USDCAD is trading as a dollar pair, a long USDCAD next to a short NZDUSD or a long USDCHF is mostly the same bet. With two positions that each risk 1% of the account, the typical swing of the pair is about the square root of (1 + 1 + 2 × correlation) percent:

Shorting NZDUSD flips the sign of the -0.69 reading, so the two positions move together at +0.69. Either way, if both stops are hit you still lose the full 2%. If both trades express one view on the US dollar, give that view one risk budget and split it.

Sizing USDCAD: a pip is not $10

USDCAD is quoted in Canadian dollars, so one pip on 1.0 lot (100,000 units) is worth 10 CAD. At 1.4046 that is 10 ÷ 1.4046 = about $7.12 per pip, $0.71 on 0.10 lot and about $0.07 on 0.01 lot. The same pip stop therefore needs a bigger position on USDCAD than on EURUSD to risk the same dollars. Example with a $10,000 account and a 1% budget of $100:

Lots are rounded down to the 0.01 step so the risk never goes above plan, and the USDCAD pip value moves a little as the rate moves. Run your own numbers in the USDCAD lot size calculator or the position size calculator. The full method, including accounts in other currencies, is in how to calculate lot size in forex.

A five step USDCAD check for this week

1. Read the 1M and 3M USDCAD readings in the forex correlation matrix instead of assuming the oil rule.
2. Decide whether your idea is about the US dollar, the Canadian dollar or oil.
3. If it is a dollar idea, count USDCAD and other dollar pairs as one risk budget.
4. Size USDCAD at about $7.12 per pip per 1.0 lot at today's rate, not $10.
5. Mark October 28 at 09:45 ET, and check the trade with the risk reward calculator before the announcement. For more on how pairs drift apart, read AUDUSD vs EURUSD correlation.
