[DAILY TRADING]: USD/CAD Analysis 18 August 2026: USD/CAD Holds 1.3872 as 50% Tariffs and Oil Both Loom Large

USD/CAD traded at 1.3872 as of 05:15 (GMT+8) on 18 August 2026, barely moving despite a news list long enough to jolt most pairs. Whether you type it USD/CAD, USD to CAD, or USD / CAD: the pair swung from a low near 1.3841 to a high above 1.3890 on Monday, then settled back where it started. A tug-of-war between a soft Dollar and a firmer Loonie, and neither side is winning yet.

What’s Actually Moving USD/CAD Today

Start with the US half of USD and CAD. The US Dollar Index (DXY) sits close to a two-month low, near 99.65 in Asian hours on 18 August, up 0.1% but not far from the session’s 99.527 trough, Reuters reported.² A month of soft US jobs, inflation and retail sales data has chipped away at bets on a near-term Federal Reserve hike. For more, Vantage’s Federal Reserve News hub is worth a bookmark.

Then there’s oil, complicating any CAD to USD forecast. Brent crude climbed to 90.97 US Dollars a barrel on 18 August, a third straight daily gain, Trading Economics reported.³ The US-Iran ceasefire lapsed on Monday, with Tehran signalling a “fully offensive” posture, keeping oil supported into Tuesday’s session, Reuters said.⁴ Canada is a major oil exporter, so firmer crude usually lifts the Loonie too. More sits in Vantage’s Brent Crude Oil News coverage.

Canada’s Inflation Beat and the Widening Rate Gap

Canada’s headline CPI rose 3.0% year-on-year in July, up from 2.8% in June and hotter than the 2.9% consensus, Statistics Canada confirmed on 17 August.⁵ Gasoline, up 25.7% year-on-year, and World Cup travel costs did the heavy lifting, while grocery inflation cooled to 3.1% from 3.9%. Core inflation, on the BoC’s preferred gauges, averaged a tame 2.0%.⁶

That mix fits the Bank of Canada’s (BoC) mood: hold and wait. The BoC kept its rate at 2.25% on 15 July, a sixth straight hold, citing Middle East and trade uncertainty.⁷ Its next decision lands 2 September.

The Federal Reserve, meanwhile, held its range at 3.50% to 3.75% on 29 July, though three of nine voters dissented in favour of a hike, a hawkish tell.⁸ That gap between USD and CAD policy rates would normally put the greenback well in front. Instead, USD/CAD sits well under its June high near 1.4248, suggesting Dollar sentiment and oil have done more lifting than rate math alone.

Levels Traders Are Watching

On the 15-minute chart behind this USD/CAD forecast, the 50 and 200-period moving averages have converged almost exactly on price, at 1.38723 and 1.38725, usually a sign of pause rather than plan.¹ The RSI reads 48.34 against its own 54.45 average, a shade soft and consistent with fading momentum after Monday’s bounce.¹

Zoom out and RoboForex’s weekly note for 17 to 21 August pegs support at 1.3872 and 1.3825, resistance at 1.3973 and 1.4059.⁹ FXStreet’s Monday read had the pair capped by a trendline near 1.3913 and the 100-hour SMA at 1.3915, with the 200-hour SMA further out at 1.3955.¹⁰ These are levels traders are watching, never instructions. New to oscillators? Vantage’s RSI explainer is worth a look.

What to Watch Next

The next big date isn’t a data release, it’s a deadline. Additional US tariffs of 50% on Canadian goods, worth close to $20 billion a year in trade, take effect from 12:01am Eastern Time on 19 August under Section 338 of the US Tariff Act, Bloomberg reported.¹¹ Dairy, alcohol and motor vehicle products are named, capping weeks of Ottawa-Washington talks aimed at avoiding it. 

The Fed’s July minutes land the same day, fleshing out how close that 9-3 vote really was.⁸ Fed Chair Kevin Warsh’s expected Jackson Hole remarks and the BoC’s 2 September decision add to a busy few weeks for anyone in USD and CAD. A shift in the Strait of Hormuz situation could matter more than any single print. For the full USDCAD news thread, Vantage keeps a running page.

Risk Considerations

Tariff deadlines, central bank speak and Middle East headlines all land on one pair, and USD/CAD tends to move fast when they do. A Stop Loss order lets traders define, in advance, the point at which a position closes, rather than reacting after the fact. Vantage’s forex risk management guide covers position sizing in more depth, worth a look before the tariff clock runs out.

Leverage lets a trader control a bigger position than their account balance alone would cover, and Vantage offers up to 1:1000 on eligible accounts. It cuts both ways: the same leverage that magnifies a good move magnifies a bad one just as fast, worth remembering with so much on the calendar. Vantage’s leverage guide breaks down the ratios; the forex trading hub covers everything else moving markets.
