EURUSD vs USDCAD Correlation: Live Readings, Risk Stacking and Lot Sizing

Why EURUSD and USDCAD usually oppose each other

EURUSD is the price of one euro in US dollars. USDCAD is the price of one US dollar in Canadian dollars. A stronger dollar pushes EURUSD down and USDCAD up in the same session. That shared dollar leg is why the correlation coefficient between the two is usually negative.

Each pair also carries its own currency. ECB decisions and euro area data move the euro alone. Bank of Canada decisions, Canadian jobs and oil linked flows move the loonie alone (see the BoC policy interest rate page). On a Canada day, USDCAD can swing while EURUSD barely moves, and the short window reading softens.

A coefficient of +1 means the daily moves always line up, 0 means no linear link and -1 means they always move in opposite directions. Over the last three months, EURUSD and USDCAD closed in opposite directions on 48 of 66 ECB fixing days (73%), and in the same direction on only 16 of 66 (24%).

EURUSD vs USDCAD correlation by time frame

The inputs are ECB euro reference rates (see the ECB reference rates page) loaded through the Frankfurter exchange rate API, converted to dollar pairs and compared as daily percentage returns. All windows end on November 5, 2026.

How to read it in practice:

• Around -0.5 to -0.7: a long EURUSD and a long USDCAD partly cancel on the dollar. That is the three month to two year picture.
• Near -0.3 or weaker: Canada specific moves dominate, so the hedge is unreliable. That is the October to early November 2026 reading.
• Check the live number on the EURUSD vs USDCAD tool page before you treat either pair as a hedge for the other.

Where each pair sits against the other majors

Context for both legs on the same three month and one year windows. EURUSD still tracks GBPUSD most closely. USDCAD still tracks USDCHF most closely among the dollar base pairs.

Why the link softened in late October 2026

From October 5 to November 5, 2026, EURUSD rose only 0.18% (1.1204 to 1.1224) while USDCAD fell 2.02% (1.4253 to 1.3966). The Canadian dollar did the work. Rolling three month correlation, which had sat between about -0.58 and -0.68 from May through September, eased to -0.54 by November 5, and the one month reading dropped to -0.27.

Policy sat behind part of that CAD move. On October 28, 2026 the Bank of Canada raised its overnight rate target by 25 basis points to 2.5% (see the BoC October 28 press release), while the Federal Reserve held the federal funds target range at 3.75% to 4% the same day (see the FOMC statement). A Canada led move is exactly when you should not treat a long EURUSD as a clean hedge for a long USDCAD.

EURUSD vs USDCAD side by side

EURUSD pays $10 per pip on 1.0 lot because the quote currency is the dollar. USDCAD pays 10 Canadian dollars per pip on 1.0 lot, about $7.16 at 1.3966. The two pairs move a similar number of pips a day, so a USDCAD stop in pips often needs a slightly larger lot to risk the same dollars.

How much risk you stack trading both

Two positions that each risk 1% swing together like one bigger position when they are correlated. The combined swing is the square root of (2 + 2 times the correlation of the two position returns), in units of one position's risk. Direction matters a lot because the raw EURUSD and USDCAD correlation is negative.

Buying both looks like a hedge on the long run numbers, close to one 1% risk unit. Selling the dollar on both charts (long EURUSD and short USDCAD) is mostly one dollar trade, and at the three month reading it swings like about 1.75%. Use the shortest window that covers your holding period. The guide to using correlation in forex covers the general rule.

Lot sizing EURUSD and USDCAD

Lots = risk in dollars divided by (stop in pips times pip value). The table uses 1% risk, a 25 pip stop on both pairs (near each three month median daily move), $10 per pip on EURUSD and about $7.16 per pip on USDCAD at 1.3966, rounded down to 0.01 lot.

If both trades are the same dollar idea on a $10,000 account, splitting one $100 budget gives 0.20 lot on EURUSD ($50) and 0.27 lot on USDCAD (about $48). Check your own numbers with the EURUSD lot size calculator, the USDCAD lot size calculator or the position size calculator.

A five step check before trading both

1. Open the EURUSD vs USDCAD correlation page and compare the 1M and 3M values with 1Y.
2. Name the leg: dollar, euro or Canadian dollar. A BoC day is not an ECB day.
3. Check EURCAD: if it moves strongly, the move is about the euro versus the loonie, not only the dollar.
4. If both trades sell the dollar, give them one risk budget and split it.
5. Size each leg from its own stop: $10 per pip on EURUSD, about $7.16 per pip on USDCAD at 1.3966.
