Oil ends October at six-month high: active Brent $113.43, WTI $104.12

Oil futures closed Friday at their highest levels since late April, finishing a volatile October with another move higher. The active January Brent contract settled at $113.43 a barrel, up $2.63 for the session, while December West Texas Intermediate settled at $104.12, up $2.12, or 2.08%, according to Reuters.

Those are final Friday settlements, not live weekend prices. Futures are closed, and the contract roll matters. December Brent expired Friday at $117.64 after rising 2.4%. January Brent, which settled $4.21 lower, is now the more relevant benchmark. The gap does not mean oil suddenly fell $4.21. It reflects two different delivery months in a market where near-term barrels command a premium.

Reuters reports double-digit gains for the rolling benchmarks

Reuters reported that the rolling front-month Brent benchmark gained 13.6% in October and its WTI counterpart rose 15.2%. A rolling benchmark changes its underlying contract as expiration approaches, so those reported figures are not the October returns of January Brent or December WTI. This report does not combine unrelated spot-price and futures-contract observations to reconstruct the monthly percentages.

The latest Energy Information Administration outlook, completed October 1 and released October 6, forecast Brent spot crude would average $105 in the fourth quarter. January futures finished Friday $8.43 above that quarterly forecast. That is not an apples-to-apples comparison between a futures settlement and a spot-price average, but it shows how much risk remains embedded at the end of the month. The EIA also cautions that its October forecast does not account for events after October 1.

Shipping risk is still setting the marginal barrel

Reuters tied Friday's rise to fears of renewed escalation in the Iran conflict and to a reported tanker attack in the Strait of Hormuz. The news service said the United Kingdom Maritime Trade Operations reported that explosive devices attached by a small boat struck a tanker. The incident adds another uncertainty to a route whose reliability directly affects the cost and timing of Middle Eastern exports.

The market is not pricing a simple one-way shortage. Exporters have used pipeline and overland routes, ship-to-ship transfers and other workarounds. The EIA's countercase is that those alternatives and a gradual return of regional production will rebuild inventories. Its October base case has Brent spot crude falling to an average of $87 in the second quarter of 2027 and $74 in the fourth quarter. Those forecasts are conditional, not promises, and the agency explicitly expects more short-term volatility than its quarterly averages show.

Who feels $100 crude first

For a small carrier or contractor, the first transmission channel is diesel rather than a futures screen. The EIA said U.S. retail diesel averaged $6.29 a gallon in September and expected it to remain above $6 in October. A truck using 1,000 gallons in a month spends $1,000 more for every $1 increase per gallon. That arithmetic does not establish where retail diesel goes next, but it explains why even a stable weekend crude price can leave operating budgets under pressure.

Households that heat with oil face a separate channel. In its winter fuels outlook, the EIA projected heating-oil prices more than 30% above last winter and household spending about 21% higher, with milder Northeast weather partly offsetting the price increase. The forecast predates the final October rally, so the next EIA update on November 10 will be the cleaner test of how the agency incorporates the latest market.

Sunday's OPEC+ meeting is the next supply test

Seven OPEC+ countries are scheduled to meet November 1. At their October 4 meeting, Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria and Oman kept required November production at September levels, according to the group's official statement. A fresh decision could change the supply outlook, but shipping capacity and conflict risk still determine how much announced production can reach buyers.

Until trading resumes, the clean weekend read is limited: active January Brent is $113.43, December WTI is $104.12, and the rolling front-month benchmarks ended October with double-digit percentage gains. Readers can track the next move on the Chronicle's crude-oil chart. The next evidence is the OPEC+ statement, any verified update on shipping through Hormuz and the November 10 EIA forecast. Those will show whether the October premium begins to ease or remains anchored in physical supply risk.
