Brent crude traded near US$116 a barrel on Tuesday, according to Reuters, after touching US$117 on Monday, its highest level since April. West Texas Intermediate was near US$102. Both benchmarks climbed through October even as officials from Saudi Arabia, Pakistan and Turkey met in Tehran on Monday to discuss a way out of the Iran war.
The chain of consequence runs in steps. Shipping through the Strait of Hormuz remains far below normal, which keeps crude and refined products tight. That holds Brent above US$100, keeps gasoline expensive and holds headline inflation above the Bank of Canada 3% ceiling. A majority of economists polled by Reuters now expect the Bank to raise its policy rate on Wednesday, and that decision reaches Canadian borrowers, bond holders and rate-sensitive equities more directly than the oil price helps energy producers.
Israel holds an election today, and DTN reported that President Trump is deciding whether to pursue an agreement with Tehran or, in the words attributed to him, to finish Iran off. The portfolio question is which of those outcomes the current Brent price already reflects.
The plotted series is the Investing.com continuous Brent contract, which trades below some front-month quotes reported by Reuters on October 27. The October 19 dip reflects a change of contract in the series. Markers show the date of the highest close since May 19 and the date of the Tehran meeting reported by DTN.
What the Strait Looks Like Now
Reuters reported that flows through Hormuz are about 60% of normal and that Gulf crude exports fell for a fourth straight week, according to ANZ Research. DTN counted eight transits in the 24 hours to Monday against roughly 60 in normal times. The two measures differ, and both sit far below normal.
Attacks on shipping are rising rather than easing. The UKMTO, the maritime trade body operated by the Royal Navy, recorded 32 attacks in October through October 21 against 16 in all of September, according to the Global Oil Shock tracker, which counts 153 incidents since March 1. Reuters cited a Washington think tank in calling October the worst month on record for attacks on shipping, and reported that the Houthis have renewed attacks on Saudi Arabia.
The buffers are being used. The International Energy Agency has released 330 million of an agreed 400 million barrels from emergency stocks, and German stocks have fallen from 90 days of cover to 82, according to the same tracker. Reuters reported that distillate inventories are nearly 5% below the five-year average, which matters because diesel and heating oil are the products that freight and winter heating depend on.
Diplomacy and the Fork in the Road
DTN reported that Saudi, Pakistani and Turkish officials met in Tehran on Monday while the Trump administration weighs its next step. Iranian Foreign Minister Abbas Araghchi has said talks are proceeding through Pakistan and Qatar, according to the Global Oil Shock tracker. Reuters noted that Israel votes on Tuesday, which adds a scheduled risk event to a week already crowded with them.
Neither track has produced a reopening. A diplomatic channel is not the same as resumed flows, and the transit counts above are the measure that would change first if talks were working. Until they do, the price of Brent is paying for a disruption that continues, not one that is ending.
The price offers a read on that fork. Reuters had Brent at US$116.26 on Tuesday, within 1% of the US$117 touched on Monday, even with talks under way in Tehran. A market pricing a near-term agreement would be expected to trade lower, and this one is pricing a disruption that continues.
Base Case, Upside Tail and Downside Tail
The base case is prolonged disruption without resolution or escalation over the next two weeks. Brent holds above US$100, transit counts stay far below normal and the diplomatic channel stays open without delivering a deal. In the Investing.com series, Brent has closed above US$100 in each of the 18 sessions since October 1, within a four-week range of US$97.09 to US$111.70.
The upside tail is a further fall in Gulf exports, driven by attacks on Saudi Arabia or on shipping. It is the more tangible tail in the data because the buffers are thinner: more than 80% of the agreed IEA release is already out, and distillate stocks are below average heading into winter. The downside tail is a credible agreement that reopens the strait, which would pull Brent lower and reduce the energy contribution to headline inflation. No agreement has been announced.
HDQ does not assign probabilities to either tail. The practical point is that portfolio and client decisions should not depend on guessing which one arrives first.
What It Means for Canadian Portfolios
Over the four weeks to October 26, Brent rose 11.0% in the Investing.com series while the S&P/TSX Composite rose 1.28% and closed 3.03% below its August high of 37,069.11. The daily relationship between the two has been weak, with a correlation of -0.18 across 18 sessions. The oil rally has not carried the index in proportion, which suggests investors are not capitalizing the full oil price into Canadian earnings.
The stronger channel is inflation. Gasoline was up 27.8% from a year earlier in September, headline CPI reached 3.1% and 19 of 34 economists polled by Reuters expect a quarter-point hike to 2.50% on Wednesday, even though CPI-trim is 1.8% and Canada lost 68,000 jobs in September. A hike would lift the lowest variable mortgage rate from 3.43% to about 3.7% and put pressure on bond funds and other rate-sensitive holdings.
Mortgage borrowers are exposed to the same chain. Government of Canada bond yields are near their Iran war peaks, and Clay Jarvis of Ratehub.ca said fixed rates are unlikely to fall significantly unless yields drop about 60 basis points, which might require a ceasefire or progress toward ending the conflict. The lowest five-year fixed rates are near 4.34%, so a geopolitical resolution would help renewing households through bond yields even before it helped through the Bank of Canada.
What to Watch This Week
The Bank of Canada announces its decision Wednesday at 9:45 a.m. ET with updated projections, which will show how much of the energy shock the Bank expects to pass into core inflation. The Israel election result, any statement from Washington on the Tehran talks and the next UKMTO incident counts are the geopolitical inputs most likely to move Brent before then.
The measure to track is Hormuz transits, not headlines. A rise toward the normal count of about 60 a day would confirm that diplomacy is working, while a further fall alongside new attacks on Saudi Arabia would move the upside tail toward the base case.
