President Trump said the U.S. will not attack Iran before the November 3 midterm elections, after reports that a pre-election strike was under consideration, according to Vantage Markets. He also described talks as productive while the blockade of Iranian ports remains in force, and Tasnim reported that Tehran is reviewing a U.S. reply to its proposal to reopen the Strait of Hormuz within seven days. Brent closed at $104.28 on October 8 after a 4.07% gain, and the question for Canadian portfolios is whether the pause removes a risk or only postpones it.
How a Hormuz Premium Reaches a Canadian Portfolio
The chain has three links. Crude prices feed gasoline, and the Bank of Canada attributed headline inflation of 3.0% in August mostly to gasoline when it held at 2.25% on September 2, with inflation at 2.2% excluding it. The Bank also said upside risks to its inflation forecast have increased, which is why the two-year Government of Canada yield was 3.25% on October 8, 1.00 percentage point above the policy rate. And because Canada is a net oil exporter, the same prices lift the earnings of energy producers that weigh heavily in the TSX, which stood at 35,136.47 on October 8, 4.9% below its August 25 close.
Oil is therefore both a cost and an income for Canadians, and which effect dominates depends on the portfolio. A household sees the cost at the pump and in a mortgage renewal priced off a five-year yield of 3.60%. An energy-weighted portfolio sees the income. The October 28 Bank of Canada decision is where the two meet.
What Brent Is Pricing and What WTI Is Not
Brent has closed above $100 on 15 of the 22 sessions since September 9 while WTI has not closed above that level since September 17, and the quoted gap between them widened from $5.16 to $12.79 over the period. Part of that widening reflects contract months, since the November Brent contract expired at $103.50 on September 30 and the series now quotes December, which was $98.03 that day.
Brent is the continuous front-month series as quoted by Investing.com; the November contract expired at $103.50 on September 30, so some day-to-day gaps reflect contract months as well as price. The September 22 marker follows an unnamed senior Iranian official quoted by Reuters.
The analyst reading is that Brent is priced for Hormuz risk and WTI for Hurricane Isaias, which shut in about 1.3 million barrels per day of U.S. Gulf output, according to Reuters as cited by Vantage Markets. That matters because the supply that has already returned is large: Goldman Sachs estimated on September 30 that Gulf exports had recovered to 23.3 million barrels per day. A Reuters poll the same day put the 2026 Brent average forecast at $89.05, well under the current price, which says analysts expect the premium to fade and have not yet seen it do so.
Three Outcomes Before November 3
The probabilities below are HDQ judgments, not market-implied figures, and they cover the period through the midterms.
Base case, about 60%. Talks continue, the blockade stays, and tanker harassment persists without a decisive break. Brent stays inside the $95 to $110 range of the past 22 sessions, where its low was $95.41 on September 22 and its high $108.75 on September 15. The U.S. statement removes a scheduled strike from this period, but nothing in it constrains attacks by other parties on shipping, as October 8 showed.
De-escalation, about 25%. A framework for reopening Hormuz is agreed in exchange for easing of the blockade, which is the trade the Iranian official described on September 22. Brent revisits the September 22 low and tests the $89.05 poll average. Hamad Hussain of Capital Economics cautioned that tolls and fees remained unresolved, and a single unnamed source is a thin basis for assuming this outcome.
Tail risk, about 15%. Talks collapse or tanker losses escalate before the election, and Brent moves through the September high toward the 52-week high of $126.41. The pre-election pause lowers the odds of a U.S.-initiated strike, but the odds of a miscalculation at sea are not zero, and they rise if the blockade and the reopening talks stay unresolved.
The Dates That Move the Odds
The U.S. CPI release on October 14 and the Federal Reserve decision on October 28 follow a 25 basis point hike to 3.75% to 4.00% on September 16, and both interact with oil through inflation expectations. The Bank of Canada decides the same day, October 28, with September CPI due before it. The midterms on November 3 are 25 days away. A stalemate through those dates keeps the oil premium in place, and a signed reopening framework would remove it faster than the data schedule can.
