The Saudi East-West pipeline was Riyadh's answer to the Hormuz closure, a 4 to 5 million barrel-a-day route to the Red Sea that did not need the Strait at all. Drone strikes shut it down September 10 and 11. The mechanism from there to Canadian portfolios is direct and already visible.

WTI crude closed at $102.48 on September 10, up 25 per cent since mid-August, as U.S. strikes on Iranian tankers and Iranian retaliation against ships using unauthorized routes have cut Hormuz traffic by more than a third.

WTI has surged since the U.S. and Iran began trading strikes on tankers in the Persian Gulf. The currency that usually tracks Canadian energy windfalls closely has barely moved, and that gap is the real portfolio question.

The Bank held at 2.25% on September 2 and named gasoline-driven inflation as the reason to stay cautious. WTI has moved 7% higher since, ahead of the CPI print that lands before the October decision.

WTI crude closed at $92.72 Tuesday after Iran-aligned Houthi forces struck three Saudi Aramco facilities, and the mechanism that changed is more consequential for Canadian portfolios than the price level itself.

Canada’s new retaliatory tariffs and the Bank of Canada’s inflation warning raise the odds the prescribed rate rises before the mechanism that fixes an income-splitting loan’s rate for life resets it higher.

Brent has risen 4.5% in two sessions after the U.S. struck Iranian positions accused of preparing to mine the strait itself, not just harass shipping, and that distinction matters for how far the Canadian energy trade can run.

Monday's tanker attacks and the first direct US-Iran exchange in a month reopen a risk premium markets spent August pricing away. The mechanism runs straight through Canadian energy, the loonie, and tomorrow's Bank of Canada decision.

July CPI came in at 3.0%, above target and rising, while an escalating trade war argues for cuts. Wednesday's decision resolves nothing; it just picks which risk the Bank tolerates longer.

WTI jumped over 3% Monday after the first American strike on Iranian territory in a month. Gold barely moved. That gap tells Canadian portfolios exactly what kind of shock this is, and what it is not.

The weekend's first US-Iran military exchange in a month caught portfolios positioned for calm. Kahneman and Tversky mapped exactly why quiet weeks make the next shock feel unprecedented.

Constructive Oman-Iran talks pushed oil to a one-month low this week. A new US-Iran exchange over sanctions erased the move within two days.

WTI peaked near $87 on August 21 and has fallen more than six percent since, even as the U.S. sanctions campaign against Iran grew tougher. The market is pricing military risk and economic risk very differently.

WTI has fallen for three straight sessions since Washington's sweeping new Iran sanctions, because the sanctions spared Iran's trading partners and a parallel Hormuz corridor deal is progressing. Canadian energy and inflation now cut in opposite directions.

Bessent's sanctions campaign is the broadest financial pressure on Iran since the war began, and oil markets read it as diplomacy, not supply disruption. The chain that would flip that reading runs through Beijing.

The CRA prescribed rate holds at 3% for a sixth straight quarter, the lowest sustained reading since 2022, just as Canada's September 8 tariffs create a parallel deadline for incorporated business owners in six exposed sectors.
