Prices fell 1.6% in Asian trade. Iran's Revolutionary Guard said a cargo ship sank after hitting a mine, the first such sinking it has reported during the war.

Brent crude futures fell $1.64, or 1.6%, to $104.42 a barrel by 03:37 GMT on Thursday. US West Texas Intermediate (WTI) fell 98 cents to $94.11. Both benchmarks reversed gains made on Wednesday, when Brent rose 0.35% after an attack on Saudi Aramco.
That attack hit Aramco's headquarters in Dhahran overnight. CNBC reported that a Houthi strike damaged the top floors of a building used by senior executives, including the chief executive's office, and caused no casualties. Production sites were not reported hit, which may explain why the earlier price rise did not hold. Israel's Globes reported on a new study arguing that the Houthis are building medium-range missiles with Chinese components and no longer depend on Iran to supply them. If accurate, that means Yemen's armed group can keep striking Gulf energy sites even if Tehran agrees to stop.
In the Strait of Hormuz, Iran's Islamic Revolutionary Guard Corps (IRGC) navy said a cargo ship sank after hitting a mine. According to AP reporting carried by OPB, it was the first time Iran had reported a sinking caused by a mine during the war. Few details emerged about the crew. Russia's state broadcaster RT described the ship as a container vessel. RT also reported that the United States released video of an attack on what it called an Iranian spy vessel.
Other signs point to a tighter market. OilPrice reported that Brent was above $106 earlier in the week, that Iran is attacking more tankers in Hormuz, and that global inventories are falling. It added that the Organization of the Petroleum Exporting Countries (OPEC) has just forecast stronger demand for next year. Thursday's price drop reflects Washington's efforts to add supply from Russia and cut freight costs, along with the fact that a strike on an office building does not reduce oil output.
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.
If Iran's claim that a mine sank the ship is accepted, Tehran's claim to control traffic through Hormuz gains weight, and so do tanker owners and war-risk underwriters, who can charge more for each transit. If the Houthis really make missiles without Iranian help, that supports the case for more Western pressure on Chinese suppliers of dual-use parts.
Both sides agree a ship went down, but they disagree on how. The Islamic Revolutionary Guard Corps (IRGC) has not named the ship, its flag or its crew, no independent source has confirmed the sinking, and a US official says Iran hit the ship, likely with a missile. On Aramco, the Saudi energy ministry called the damage a "limited fire," while Reuters sources described extensive damage to the top floors. The Houthi independence claim also overstates the evidence. Other reporting says Chinese parts often reach Yemen through Iranian ports, so Tehran's role as the route and the political sponsor remains.

What this means
Oil sold off after an attack on Saudi Arabia's main oil company because the market is distinguishing symbolic hits from damage that actually reduces output. The mine is the more significant development. Mines remain in the water after they are laid, and insurers price shipping lanes according to the risk of loss, so Hormuz war-risk premiums and charter rates can rise even on otherwise quiet days. Gulf exporters that cannot reroute oil around the strait are most exposed, along with the Asian importers that rely on it. The precedent is the 1987-88 tanker war: the US Navy escorted convoys, mines kept damaging ships, and freight and insurance costs stayed elevated for most of a year. Our forward read: if Iran continues mining the strait or attacking ships there, Brent's floor above $100 is likely to hold for months, falling only if Washington releases more Russian or other non-Gulf barrels onto the market. A verified agreement to clear the mines, or a pause in IRGC attacks on ships, would prove this wrong.

Brent trades about $10.31 above WTI, a spread that prices seaborne Gulf supply risk which US inland crude does not carry, so a Hormuz escalation should widen it before it lifts both benchmarks.
