Oil watches Hormuz traffic after Iran mine warning

NEW YORK, Nov. 8, 2026 (GoldSquawk) - ICE Brent crude last settled up 6 cents at $98.36 a barrel on Friday, Nov. 6, before Iranian state media carried warnings on Sunday from the navy and the Revolutionary Guards that ships in the Strait of Hormuz risk hitting mines if they ignored Iranian rules or used unauthorized routes.

The warning matters for oil traders because the Strait remains central to the market’s supply-risk premium: Reuters reported in an Aug. 31 poll that analysts expected Brent to average above $80 a barrel in 2026 because shipping disruptions tied to the U.S.-Iran conflict were reducing supplies, while the U.S. Energy Information Administration said on Oct. 6 that ongoing global supply constraints were keeping inventories below normal.

Iranian warnings tighten the focus on Hormuz

Fars reported on Sunday, Nov. 8, 2026, that Iran’s navy warned ships ignoring Strait of Hormuz rules and cooperating with the U.S. military that they might hit a mine.

Tasnim later reported that the IRGC Navy said unauthorized vessels in the strait faced drifting mines.

Press TV then reported that an IRGC spokesman said the Strait of Hormuz was under IRGC Navy control and again warned that vessels risked mines.

Reuters reported on Sunday that Iranian media said explosions on Qeshm Island may have been Iranian military activity, while Iran’s Revolutionary Guards Navy said two oil tankers caught fire after hitting mines on an unauthorized route in the Strait of Hormuz. Reuters also said Fars later reported a third tanker suffered an explosion and fire, and Reuters said those mine-hit claims from Iranian state media could not be independently verified.

Fresh incident reports were already building

The UK Maritime Trade Operations agency logged an Attack report on Nov. 8 in the Strait of Hormuz, saying a tanker outbound had been struck by an unknown projectile, with all crew safe and no environmental impact reported.

UKMTO also logged a Nov. 8 Suspicious Activity report saying a tanker 8 nautical miles northwest of Khasab, Oman, was on fire and its crew had been evacuated.

UKMTO’s incident notices for Nov. 6 in the Strait of Hormuz and Nov. 5 in the central Arabian Gulf showed a broader run of attacks in the days before Sunday’s warning, according to the agency’s incident log.

That pattern fits a wider deterioration in merchant-shipping security. AP reported on Nov. 2 that October saw the most attacks on commercial ships in the Strait of Hormuz since March.

What traders will watch next

For crude, the next question is whether Sunday’s warning is followed by more shipping incidents in or around Hormuz after a day that already brought UKMTO reports of one tanker struck by a projectile and another tanker fire near Khasab.

That matters because Reuters’ Aug. 31 poll said analysts and economists expected Brent to stay above $80 a barrel in 2026 partly because disruptions linked to the U.S.-Iran conflict were reducing supplies, and Reuters said estimates in that poll put the global oil market in a deficit of 1.65 million to 3.5 million barrels a day this year.

The EIA also said in its Oct. 6 Short-Term Energy Outlook that global supply constraints were keeping inventories below normal through its forecast period, and that tight diesel markets were adding upward pressure to crude prices.

Beyond any new UKMTO incident notices in the Strait of Hormuz, the next scheduled oil-market marker is the EIA’s next Short-Term Energy Outlook on Nov. 10, with U.S. CPI due the same day.
