Brent crude futures [fell $1.64, or 1.6%, to $104.42 a barrel](https://www.thehindu.com/business/oil-prices-dip-as-supply-risks-from-west-asia-tensions-clash/article71586615.ece) 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%](https://www.nationthailand.com/news/world/40072291) after an attack on Saudi Aramco.

That attack hit Aramco's headquarters in Dhahran overnight. CNBC [reported](https://www.cnbc.com/2026/10/14/us-iran-war-trump-hormuz-saudi.html) 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](https://www.globes.co.il/news/article.aspx?did=1001559617#utm_source=RSS) 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](https://www.opb.org/article/2026/10/14/iran-says-a-ship-sank-after-striking-a-mine-in-strait-of-hormuz-and-other-middle-east-developments/), 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](https://rt-english.com/news/647214-hormuz-strikes-mine-vessel/?utm_source=rss&utm_medium=rss&utm_campaign=RSS) 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](https://oilprice.com/Energy/Crude-Oil/Oil-Market-Tightens-as-Tanker-Attacks-and-Inventory-Draws-Mount.html) 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.

## 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.

## What to watch

- War-risk insurance quotes for Hormuz transits. A further rise would show underwriters regard the mine threat as lasting.
- Any Houthi strike on Saudi production or export sites, rather than offices, which would turn symbolic damage into lost supply.
- Weekly US and global inventory data. Continued declines would undercut today's price drop.
