Brent Ends October Up 13.6% at $117.64 as Iran Says Four Tankers Struck Mines in Hormuz
The US military says the main shipping lanes are clear of mines, and an Iranian assessment reported by Globes expects US strikes to resume after the November 3 midterm elections.
Brent crude rose 13.6% in October to settle at $117.64 a barrel, a six-month high, according to India's Economic Times. The paper said traders priced the risk of new US strikes on Iran and of disruption to shipping through the Strait of Hormuz.
On Friday, Iran's Revolutionary Guard said four tankers had caught fire after striking mines in the strait. Ynet reported that the Guard said the ships had ignored its warnings. Tehran says the vessels used "unauthorised routes," while the US military says US forces have cleared all internationally recognized primary transit routes. Oman said it evacuated 25 crew members from a Panama-flagged tanker that caught fire 1.6 nautical miles off Musandam. No independent survey has yet established whether the ships struck mines or were attacked by other means. Each side's version carries a motive: Iran gains if shippers believe only Iranian-approved routes are safe, and Washington gains if insurers believe the main lanes remain open.
Diplomacy is running at the same time. Ynet reported that a Qatari delegation arrived in Tehran to try to advance an agreement with Washington, and US President Donald Trump said that Iran "wants to talk" and that the United States "has time." Globes reported a contrary assessment from Tehran. Iranian officials, it said, expect an opening for an Israeli-American strike after the midterms, aimed at deepening economic paralysis and later at toppling the government.
The cost is already reaching consumers. OilPrice reported gasoline up 34% and heating oil up 74% as voters head to the polls.
Part of a tracked trend
Hormuz Chokepoint Repricing
Recurring Gulf conflict forces energy exporters and importers to build costly workarounds around the Strait of Hormuz, permanently raising the risk premium embedded in Gulf trade and infrastructure.
Veracity: Plausible
40/100- If true, who benefits
If Iran's account of mine strikes holds, Tehran gains a way to push tankers onto Iranian-approved routes and raise war-risk insurance costs on all other lanes, while holders of long oil positions and Gulf producers with pipelines that bypass Hormuz gain from a higher Brent price.
- The nuance
Iran's Revolutionary Guard has given different counts of damaged tankers (two, three and four). US Central Command (CENTCOM) calls the mine claim false and says Iran uses missiles and drones. Oman's navy says a small boat attached two explosive devices to the hull of the Panama-flagged RITI. That means at least one of the fires came from a deliberate attack and not from a mine, and no party has publicly identified who carried it out.
An open-source-intelligence read of how likely this story is true with its real nuance, not a judgment of any outlet. It assesses the claim, weighing independent and adversarial reporting. .

Brent's 13.6% October gain implies a start near $103.60, giving a dated test: much of that $14 should unwind if no US strikes follow the November 3 midterms.
