A closer look at why the loonie is being pulled in two directions at once — by a crude supply scare in the Gulf and by fresh American restrictions on Canadian vehicles and dairy.
The Canadian dollar held its ground against the greenback on Tuesday, with USD/CAD staying subdued near 1.3780 for a third consecutive session as elevated crude oil prices cushioned the currency against a fresh round of American trade restrictions. The pairing of a firmer commodity backdrop with a deteriorating trade relationship left the loonie unusually well supported for a currency whose largest export market is actively tightening access.
It is a split-screen market. On one side, a supply scare in the Gulf has pushed crude higher and lifted the currencies of oil-exporting economies. On the other, Washington has widened the list of Canadian goods facing restrictions, including motor vehicles and dairy, after both countries escalated tariffs against each other.
USD/CAD Stalls Near 1.3780 for a Third Straight Session
The most telling feature of this week’s trade is not the level but the lack of movement. USD/CAD has sat close to 1.3780 across three sessions, a sign that buyers and sellers are roughly balanced rather than that either side has won the argument.
Currency markets tend to go quiet like this when two large forces are pushing in opposite directions. Higher oil normally lifts the Canadian dollar; escalating trade barriers with the United States normally weigh on it. For now, those two impulses are broadly cancelling out.
That stalemate matters for anyone pricing cross-border contracts, hedging US-dollar receivables, or planning import costs for the fourth quarter. A flat rate is not the same thing as a stable one — it can be the calm before a sharp break in either direction once one of the two drivers resolves.
The Kharg Island Strike and the Crude Supply Premium
The oil leg of the story stems from a US strike on Iranian tankers near Kharg Island, which raised fears of supply disruption and pushed crude prices higher. Kharg Island sits at the heart of Iran’s crude export infrastructure, and any military activity in that corridor tends to be read by traders as a threat to physical barrels reaching the market.
Markets typically respond to that kind of event by adding a risk premium to the price of oil — not because supply has already been lost, but because the probability of losing it has risen. That premium can deflate quickly if shipments continue uninterrupted, which is precisely why an oil-supported currency move can be fragile.
For Canada, the mechanism is straightforward. Higher benchmark crude prices improve the value of the country’s single largest export category, strengthen the terms of trade, and increase demand for Canadian dollars to settle energy transactions.
Why Oil Still Moves the Loonie
The Canadian dollar is one of the market’s classic commodity-linked currencies, and Canada’s position as a leading crude exporter is the reason. When oil rallies, the loonie usually finds a floor; when it slumps, the currency tends to follow.
Three channels drive that relationship in practice:
- Export revenue: Crude and refined products make up a large share of Canadian export earnings, so price swings feed directly into the national income picture.
- Investment flows: Sustained higher prices tend to draw capital toward Canadian energy projects and energy-linked equities, both of which require Canadian dollars.
- Rate expectations: Energy prices shape headline inflation, and inflation shapes what traders expect from the central bank — which in turn feeds back into the currency.
That last channel is live right now. Expectations around inflation and the possibility of rate increases are influencing both commodity and currency moves, adding another layer of sensitivity to every energy headline. Readers following the domestic borrowing picture can see how those expectations are filtering through in our coverage of how the mortgage rate forecast shifted after the Bank of Canada held at 2.25%.
New US Restrictions on Canadian Vehicles and Dairy
Working against the currency is the trade file. New US measures restrict Canadian exports including motor vehicles and dairy products, arriving after a period of mutual tariff escalation between the two countries.
The choice of sectors is significant. Motor vehicles and parts represent one of the most deeply integrated cross-border supply chains in the world, with components frequently crossing the border several times before a finished vehicle is sold. Restrictions there do not fall on a single exporter — they ripple through plants, parts suppliers, and logistics operators on both sides.
Dairy has long been the most politically sensitive corner of the Canada-US trade relationship because of Canada’s supply-management system. Including it in a new restriction package signals that the dispute has moved beyond a narrow set of industrial goods.
Public sentiment has hardened alongside the policy. Our earlier reporting found that 73% of Canadians reject making concessions in trade talks with the United States, which narrows the room any negotiator has to strike a quick compromise.
Gold Rebounds From a One-Week Low Near $4,350
The same risk backdrop is visible in precious metals. Gold rebounded from a one-week low near the $4,350 level, recovering as geopolitical tension and inflation expectations drew buyers back.
Gold and the Canadian dollar are responding to overlapping but not identical forces. Gold is being bid as a hedge against conflict risk and price pressure, while the loonie is benefiting from the commodity revenue side of the same story. When both firm at once, it usually indicates that markets are pricing genuine supply and policy uncertainty rather than simple risk appetite.
What This Means for Canadian Businesses and Households
For exporters outside energy, a resilient Canadian dollar is a mixed blessing. It trims the currency cushion that normally softens the blow of weaker foreign demand, at the very moment US market access is being restricted for vehicles and dairy.
For importers and travellers, a steady rate near 1.3780 offers short-term planning certainty on US-dollar costs. For households, the more relevant transmission is energy prices: elevated crude eventually shows up at the pump and in transport-linked goods, feeding the inflation expectations that shape borrowing costs.
Equity markets are reading the same signals from a different angle. The TSX Composite’s slide of 1.11% to a one-month low underlines how quickly trade and commodity headlines are being repriced by Canadian investors.
The Two Variables Worth Watching
The near-term direction of the Canadian dollar rests on how two specific questions resolve, and neither has a scheduled answer:
- Whether the crude premium holds: If tanker traffic near Kharg Island continues without disruption, the supply fear that lifted oil can fade — removing the loonie’s main support.
- Whether trade escalation continues: Further restrictions, or retaliation, would extend the pressure already built into the vehicle and dairy measures.
No timeline for either has been announced. Until one of them shifts decisively, the balance that has pinned USD/CAD near 1.3780 for three sessions is likely to remain the defining feature of the market.

Frequently Asked Questions
Why does a strike on Iranian tankers affect the Canadian dollar?
It pushes crude prices higher on supply-disruption fears, and because Canada is a leading crude exporter, higher oil generally strengthens the commodity-linked Canadian dollar.
Which Canadian exports are covered by the new US measures?
The reported restrictions include motor vehicles and dairy products. No full list beyond those categories was specified.
What does USD/CAD near 1.3780 mean in practice?
It means roughly 1.3780 Canadian dollars are needed to buy one US dollar — a level that has held with little movement across three sessions.
Why did gold rise at the same time as the Canadian dollar?
Both are reacting to the same geopolitical and inflation uncertainty. Gold rebounded from a one-week low near $4,350 as a hedge, while the loonie drew support from the resulting rise in crude prices.
