What happened
Saudi Arabia contained a fire near its biggest oil export terminal, at Ras Tanura on the Gulf coast, in the early hours of Tuesday, Bloomberg reported, citing a person familiar with the matter. The extent of damage was unclear, and Aramco did not immediately respond to Bloomberg. The Houthis say a ballistic missile hit the Ras Tanura refinery and started a fire. Saudi authorities have not confirmed a strike, Reuters reports. The coalition says it destroyed three Houthi missiles fired at the Eastern Province overnight and two aimed at Riyadh later, where explosions were heard (CBS News).
Iran's Persian Gulf Strait Authority says it will take "legal action" against all vessels of South Korea's Sinokor from November 1, Bloomberg reports. Sinokor ships carried nearly 40% of the crude that left the Strait of Hormuz in September.
Why it matters
Ras Tanura and Yanbu handle nearly all of Saudi Arabia's oil exports, according to Reuters. No loading halt has been announced, and the market is not pricing one. December Brent was $114.14, down 1.4% on Monday's settlement. We hold our threat assessment at 8/10 until the cause and the damage are confirmed.
Iran has not said what "legal action" means. Charterers and war-risk underwriters have until Sunday to decide whether a Sinokor tanker is still an acceptable risk in the strait.
What to watch
Watch for an Aramco statement, Ras Tanura loadings and Sinokor's reply. Iran's navy also says a tanker hit a mine east of the strait; UKMTO has no matching report. Our morning brief covers Iran's seven conditions for talks.
