0. Overnight Arc

• **[ESCALATED] Maritime shock:** The IRGC said two tankers exploded and caught fire after striking naval mines in the Strait of Hormuz; Al Jazeera separately reported a tanker on fire after a mine strike ^[1][2][3].

• **[ONGOING] Broader risk load:** As of Nov. 13, UKMTO had counted 163 Iran- and US-conflict-linked maritime incidents year to date, eight more than on Nov. 6, plus 173 maritime-security warnings and 23 safety notices ^[5].
• **[NEW] Flow-versus-risk split:** Gulf oil exports were reported recovering even as Hormuz shipping struggled ^[6].

1. Mechanism: Mines, Fire and the 90-Day Bridge

• **[NEW] Operational bridge:** President Donald Trump will extend the shipping exemption for oil and fertilizer by 90 days ^[8].
• **[NEW] Data friction:** Microsoft's global service outage forced some trading teams to use phone, fax and instant messaging; Platts delayed updates and paused 22 biofuel prices, while Microsoft said more than 20 products and services might still show errors during recovery ^[9].
• **[ONGOING] Risk premium:** Bloomberg's Rebecca Patterson said Iran could retain greater influence over Hormuz, keeping shipping and insurance costs elevated even as oil flows resume ^[10].

2. Gulf Security and Policy Triggers

• **[ESCALATED] Yemen escalation:** The Houthis said they used drones and ballistic missiles to hit a Saudi-led coalition arms depot and a coalition assembly point in southern Yemen, directly hitting the targets and causing casualties ^[11].
• **[ESCALATED] Counter-strikes:** The Houthis said the Saudi-led coalition launched 85 airstrikes and missile attacks across six Yemeni provinces in the prior 24 hours, taking the total since the latest escalation to 4,948 ^[12].
• **[ESCALATED] Sirik escalation:** Iran's military said its navy intercepted and hit a U.S. MQ-1 drone in the Kohgestak area near Sirik ^[13]. A separate houseofsaud.com headline relayed an IRGC Aerospace Force warning of an “unlimited response” over Hormuz after the Sirik strike ^[14].
• **[ONGOING] Israel:** Israeli Chief of Staff Zamir favored postponing immediate renewed military action against Iran, arguing that the threat was real but not yet urgent and that action could serve Netanyahu's political purposes before a new government formed; Netanyahu and several officials he appointed opposed him ^[15].
• **[ONGOING] Naval coordination:** An Israeli military statement said U.S. Fifth Fleet Commander Kete Lunxiao visited Israel at Israeli Navy Commander Ayal Harrell's invitation and met senior commanders on naval operations, fleet coordination, partner relations and technical sharing ^[16].
• **[NEW] Regional pact:** Turkish President Erdogan and Qatari Emir Tamim signed a mutual defense agreement, although it was unclear whether it included an attack-on-one clause similar to the August pact among Turkey, Saudi Arabia and Pakistan; the new pact also calls for deeper energy and defense-industrial cooperation ^[17].
• **[ONGOING] U.S. posture:** NPR characterized Trump's strategy as preserving the status quo, with Gulf Arab allies favoring it and midterm politics shifting the approach from threats of attacks toward economic pressure ^[18].

3. Market and Revenue Read

• **[NEW] Export volume, headline-level:** gCaptain reported that Gulf oil exports were recovering while Hormuz shipping continued to struggle ^[6].
• **[ONGOING] Fiscal spillover:** The IEA said Russia's October crude and petroleum-product export revenues reached the highest level since May because the Iran war boosted oil prices ^[19].
• **[ONGOING] Inflation channel:** Charles Schwab Chief Investment Strategist Liz Ann Sonders and Council on Foreign Relations Senior Fellow Rebecca Patterson discussed how higher fuel and refined-product costs may feed inflation and complicate Federal Reserve policy ^[10].
• **[NEW] Trading plumbing:** Platts delayed updates for some refined products, natural gas and biofuels, suspended 22 biofuel prices, and later said the related incident was resolved; some traders used phone and fax for price reports and orders ^[9].
• **[ONGOING] Market tension:** Physical flows can recover while shipping and insurance costs may remain elevated, according to the Bloomberg assessment ^[10][6].

4. Falsification and Watchlist

• **[ONGOING] Verify the vessel event:** Independent confirmation of whether the reported tankers and gas carrier struck naval mines, and of the Oman-coast fire, would materially strengthen or weaken the maritime-risk signal ^{[1][2][4][3][7]}.
• **[ONGOING] Test the flow split:** A sustained recovery in Gulf exports alongside a lower UKMTO incident tally would weaken the acute-disruption reading, while new mine or fire reports would strengthen it ^[5][6].
• **[NEW] Watch the waiver:** Whether the planned 90-day oil and fertilizer shipping exemption translates into lower shipping or insurance pressure is the near-term test, although Bloomberg cautioned that costs may persist after flows resume ^[8][10].
• **[ONGOING] Policy threshold:** A move by Israel toward immediate action would run against Chief of Staff Zamir's current preference, while NPR's account of a status quo and economic-pressure strategy points instead to stalemate ^[15][18].
• **[NEW] Data resilience:** A recurrence of price-reporting or order-routing failures would show that the Microsoft outage was more than a temporary operational interruption ^[9].
