Hours after doubting it, traders see a strike on Saudi oil pipeline this month as likely

Traders swung on Monday to expecting a strike on Saudi Arabia's East-West oil pipeline this month, a sharp reversal from hours earlier, when they considered one unlikely. Bets surged by roughly half the scale in about half an hour, and the reason is not clear. No credible report reviewed for this story describes a new attack on the pipeline or its pumping stations around the time of the jump.

The odds have been volatile all month. Early in November they hovered around the unlikely-to-toss-up range, then fell on November 3 after Bloomberg reported that U.S. and Iranian officials were reviewing fresh Qatari proposals. That report is background, and nothing confirms it drove the drop. Bets sank further by November 6, then spiked briefly on November 7 and flickered on November 8 before settling back. They were flat for most of Monday until the late jump.

The pipeline, also called the Petroline, carries crude from the Eastern Province to Yanbu on the Red Sea and bypasses the Strait of Hormuz. Drones launched from Iraq damaged the line in September, prompting a shutdown. That attack does not count toward this month's question. A report on November 6 described another closure, but its own account dates the attacks to September 10, so a new closure is unverified.

The question requires an air strike or a surface-to-surface strike that actually impacts the pipeline or its pumping stations. Intercepted weapons, falling debris, surface-to-air missiles, artillery and small drones do not qualify. On November 8, Saudi Arabia said debris from an attempted attack damaged an Aramco office building in Riyadh, not the pipeline. On November 6, the U.S. carried out a limited strike on an Iranian air-defense launcher while mediation continued.

Bets on related questions barely moved. Traders still see the Israel-Iran ceasefire continuing through November as likely and a U.S.-Iran Hormuz agreement as unlikely, which suggests the pipeline jump was specific to this question.

President Trump was scheduled to meet Qatar's prime minister on Monday about mediation with Iran. Axios reported the proposal concerned a ceasefire and renewed nuclear talks, not a confirmed agreement. Whether the pipeline is hit will depend on Saudi government statements and credible reporting that a qualifying strike actually landed.
