The S&P/TSX composite closed Tuesday up 575.45 points, 1.63%, its strongest session in weeks, on what wire reports described as optimism the Strait of Hormuz could soon reopen. WTI crude fell 6.36% the same session, down 13.6% from its July 23 peak of $87.01.
The trade connecting those two moves is straightforward: a reopened strait means restored supply, restored supply means lower oil, and Canadian equities not tied to energy rallied on the relief. What is less straightforward, and worth tracing carefully before extending that trade, is what is actually being negotiated in Muscat this week.
What the Market Priced Versus What Is on the Table
According to Iranian, American, and Omani officials cited by the New York Times and the Oman Observer on Tuesday, the emerging arrangement gives Iran and Oman 60 days to negotiate the strait's opening. During that window, ships heading into the Gulf would transit a channel controlled by Iran and close to its coast; ships leaving would use a channel near Oman's. Iran would charge no formal toll but a "service fee" covering security, environmental impact, and staffing.

Separately, a member of Iran's negotiating committee told state broadcaster IRIB on Tuesday that the goal is an arrangement lasting one to three months in which Iran is, in his words, dominant: security, demining, and maritime services all handled by Iran. Reuters reported Tuesday that Iran wants control over inbound shipping and visibility over outbound traffic, with the ability to intervene if it judges necessary.
Washington and Tehran Are Not Describing the Same Deal
A US official told reporters Monday that the Iranian characterization of the talks was, in that official's words, not accurate, and said any temporary route would not involve Iranian approvals or permissions, and would carry no tolls. That is a direct contradiction of what Iran's own negotiators were telling their own state media the next day.
Inside the Pentagon, officials briefed on the talks have reportedly voiced concern the arrangement amounts to a concession that ratifies Iranian control over what was, before February, an open international waterway. Extensive mines reportedly remain in the strait regardless of which flag is on the negotiating table, meaning vessels will need to coordinate with Iran to transit safely even on the route the United States has been protecting.
The Base Rate This Market Has Not Yet Priced
This is not the first time in 2026 that a Hormuz de-escalation has been priced as durable. The June 17 memorandum of understanding ending the initial war produced a similar relief rally before Washington declared it over on July 8 and resumed strikes, sending WTI up 4.4% in a single session. President Trump has predicted the strait could reopen "literally by tomorrow" on multiple occasions since the war began in February, a claim that has not yet been correct.
None of that means the current talks will fail. It means the base rate for an announced Hormuz de-escalation converting into a durable resolution, rather than a time-limited arrangement that reopens the same question in one to three months, has not been strong this year. A structure both sides are describing as temporary, with a negotiated shelf life stated by Iran's own side, is not the same analytical category as a settled reopening, whatever the market did with it Tuesday.
The Canadian Chain: From Corridor Control to Q3 Export Revenue
Statistics Canada's June trade release, published Tuesday, showed second-quarter exports rising 13.1%, the strongest quarterly gain since the third quarter of 2020, with almost half of that increase tied to elevated energy prices flowing directly from this conflict. That tailwind, and the trade surplus and GDP contribution built on it, is a function of exactly the risk premium this week's talks are trying to remove.
If the arrangement now under negotiation is the narrow, Iran-administered, one-to-three-month structure both Iranian officials and Pentagon sources describe, rather than the clean reopening equity markets priced Tuesday, the risk premium supporting Canadian energy revenue is more likely to prove conditional than resolved. A Canadian portfolio with meaningful energy-sector weighting is exposed to that gap between what was priced and what was actually agreed to, and the exposure runs in both directions: a genuine reopening compresses energy-sector revenue from here, while a fifth round-trip on the same narrow arrangement leaves the current price support, and the export and GDP data built on it, more fragile than this week's headlines suggest.
