Why it matters: Oil’s renewed strength reflects a real shift in the Hormuz story, with Washington and Tehran hardening their positions rather than converging on a settlement. CAD is trading energy directly, USD is trading what energy means for Fed policy ahead of Wednesday’s CPI, and AUD has almost nothing to do with either trade. Tuesday’s FX leadership is two separate transmission channels, not one macro trade wearing three currency labels.
Why Oil’s Rally Is Really About a Hardening Hormuz Standoff
Oil’s renewed strength reflects a deeper shift in the Hormuz story: markets are becoming less convinced that Washington and Tehran are moving toward a workable settlement.
The latest exchange makes that clear. Trump said Monday Iran should pay reparations for damage it had caused over decades, directly countering demands from Mohammad Bagher Zolghadr, secretary of Iran’s Supreme National Security Council. Zolghadr had laid out conditions for reopening the Strait including an end to the US blockade and sanctions, withdrawal of American forces, war reparations and release of frozen Iranian assets. Rather than bargaining those demands down, Washington responded with a compensation claim of its own. What had already been a difficult navigation dispute is now broadening into a larger confrontation over sanctions, security and reparations.
Iran hardened its tone again Tuesday. Foreign Ministry spokesman Esmail Baghaei dismissed Treasury Secretary Scott Bessent’s claim that sanctions were “suffocating” the Iranian economy and accused Washington of escalating sanctions whenever diplomacy fails. He called the approach less a policy than a “compulsive addiction.” That does not sound like a negotiation approaching its final compromise. For oil, the implication is straightforward: the longer the Strait remains unresolved, the more difficult it becomes to strip the geopolitical premium out of Brent. The brief move above $90 therefore matters even though prices subsequently pulled back, with $92.87 now seen as the next major technical test before $100 comes back into play.
The Widening Standoff
- Zolghadr’s conditions for reopening: end to US blockade and sanctions, withdrawal of American forces, war reparations, release of frozen Iranian assets
- Trump’s counter: Iran should pay reparations for decades of damage
- Baghaei: dismissed Bessent’s “suffocating” sanctions claim, called the US approach a “compulsive addiction”
- Brent crude: briefly broke above $90, eased back to $87-88
Oil Is Helping Dollar and Loonie for Different Reasons
That oil rally is helping Dollar and Loonie for different reasons. CAD gets the more direct benefit. Stronger crude improves Canada’s external backdrop and reinforces support already provided by last week’s robust jobs report. Dollar’s link is more indirect but equally important. Weak July payrolls raised the hurdle for another Fed hike, yet higher oil keeps the inflation problem alive. Ahead of Wednesday’s CPI, the Brent rebound gives markets another reason not to complete a full dovish Fed repricing. CAD is trading energy itself; USD is trading what energy means for rates.
RBA Gave Aussie Its Own, Separate Reason to Rally
Aussie, meanwhile, has almost nothing to do with that trade. RBA held at 4.35%, but the package was notably hawkish. Policy was described as only “somewhat restrictive,” another hike was explicitly left available if upside risks materialize, and forecast assumptions incorporate a cash-rate path rising toward 4.5%. Bullock then made the message harder to dismiss. She said the Board had considered hiking and stressed, “It’s important people believe that we will act if we need to.” More pointedly, she added: “I think personally that it’s quite possible we might need to go but we’ll wait and see what the data tells us.” That was enough to preserve the tightening bias and give AUD a distinctly domestic tailwind.
RBA’s Hawkish Signals
- Cash rate: held at 4.35%
- Policy characterization: only “somewhat restrictive”
- Another hike: explicitly left available if upside risks materialize
- Forecast assumptions: cash-rate path rising toward 4.5%
- Bullock: “It’s important people believe that we will act if we need to.”
- Bullock: “I think personally that it’s quite possible we might need to go but we’ll wait and see what the data tells us.”
Currency Performance: Two Trades, Not One
Aussie consequently leads, followed by Dollar and Canadian Dollar, while Swiss Franc sits at the bottom ahead of Kiwi and Sterling. Euro and Yen are in the middle. The useful takeaway is that Tuesday’s FX leadership is not one broad macro trade wearing three different currency labels. RBA gave AUD its own reason to outperform, while the worsening Hormuz outlook pushed oil high enough to support both CAD and USD through separate transmission channels.

Frequently Asked Questions
Q: Why are AUD, USD and CAD all higher today if they’re not the same trade?
A: They’re higher for two unrelated reasons. RBA refused to declare its tightening cycle finished, giving AUD a distinctly domestic tailwind that has nothing to do with oil. Separately, Brent’s brief break above $90 gave USD and CAD their own boost, tied to a hardening Hormuz standoff rather than anything happening in Australia. Three currencies moved together, but through two completely separate transmission channels.
Q: Why does CAD benefit more directly from oil than USD does?
A: CAD is trading energy itself, stronger crude directly improves Canada’s external backdrop and reinforces support already provided by last week’s robust jobs report. USD’s link is more indirect: weak July payrolls had already raised the hurdle for another Fed hike, but higher oil keeps the inflation problem alive ahead of Wednesday’s CPI, giving markets a reason not to complete a full dovish Fed repricing. CAD is trading the commodity; USD is trading what the commodity means for rates.
Q: What’s actually being negotiated over the Strait of Hormuz right now?
A: The dispute has broadened well beyond shipping logistics. Iran’s Zolghadr laid out conditions including an end to the US blockade and sanctions, withdrawal of American forces, war reparations and release of frozen Iranian assets. Rather than negotiating those down, Trump countered that Iran should pay reparations for decades of damage it caused. Iran’s Foreign Ministry has since dismissed US claims that sanctions are “suffocating” its economy, calling the approach a “compulsive addiction.” That’s not the tone of a negotiation nearing compromise.
Key Takeaways
- Tuesday’s FX leadership is two trades, not one: AUD is trading the RBA; USD and CAD are trading oil. All three currencies rose, but for unrelated reasons.
- The Hormuz standoff is broadening, not narrowing: Trump’s reparations counter-demand and Iran’s “compulsive addiction” rhetoric show both sides hardening rather than converging on compromise.
- Brent’s brief break above $90 matters even after pulling back: It signals markets are struggling to strip the geopolitical premium out of oil, with $92.87 the next technical level before $100 comes into view.
- CAD and USD benefit from oil through different channels: CAD gets a direct lift from stronger crude and last week’s jobs data; USD’s boost is indirect, since higher oil keeps the inflation case alive ahead of Wednesday’s CPI.
- RBA’s hold came with real hawkish signals: Policy is still only “somewhat restrictive,” another hike remains explicitly available, and Bullock said it’s “quite possible we might need to go.”
- Don’t read Tuesday’s currency moves as one broad risk trade: Grouping AUD, USD and CAD together as “the same story” misses that RBA policy and oil-driven geopolitics are doing completely separate work.
What to Watch Next
Wednesday’s US CPI is the next test for the oil-driven leg of this trade: a hot print would reinforce the case Brent’s rally is already building for USD and CAD, while a soft print would revive dovish Fed repricing despite firmer oil. On the Hormuz side, watch for whether Washington and Tehran show any sign of narrowing their positions, rather than hardening them further.
