〔Day Digest〕Tanker Strike Kills One Off Hormuz as Iran Says Strait Won't Reopen Despite Oman Deal; Houthis Take Bab el-Mandeb, Saudi Pipeline Closed — ~4-5% of Global Supply at Risk

0. Weekly Arc

The Hormuz crisis widened on Sept 13: a projectile killed one on an Iranian commercial ship near Qeshm hours before Iran-Oman channel talks in Muscat on Sept 14 ^[1][2][3]. Yet the supply shock now spans two chokepoints — Bab el-Mandeb has flipped to the Houthis after the fall of Mocha, and Saudi Arabia's East-West pipeline is offline after a drone strike ^[4][5]. Net: roughly 4-5% of global oil supply at risk on top of an already-constrained Hormuz ^[5].

1. Chokepoint Mechanics

• **[NEW] Strait of Hormuz — projectile strike, 1 dead:** an Iranian commercial ship was hit near Qeshm with 1 fatality, per Iranian media ^[1][6][2]. The UK Maritime Trade Operations office received a separate report of a vessel hit by an 'unknown projectile' inside the strait, with crew status, damage and environmental impact all unknown ^[7]. WANA reports a projectile hit two vessels ^[8]; another outlet says a Panama-flagged oil tanker was hit by a missile ^[9]. Treat as a cluster, not a point.
• **[ESCALATED] Bab el-Mandeb — Houthis in control:** 73 ships transited in 48 hours, 98.6% of the pre-July-20 Houthi maritime-embargo daily average; 'safe and smooth' for all non-Saudi international vessels ^[10]. The Houthis claim to have captured Mocha and released 210 prisoners ^[4]. Saudi Arabia shut its East-West pipeline (1,200 km, 4-5 mb/d, 4-5% of global supply) after a drone attack; injuries and damage are under assessment and no group has claimed responsibility ^[5].
• **[ONGOING] US naval posture:** more than 5,000 sailors on the USS George Washington are on high alert in the Arabian Sea supporting 'Operation Epic Fury,' per Fox News ^[11]. US Central Command says it has guided 100 ships to alter course in the past 60 days ^[12]. The US has restricted air-defense windows for oil tankers in Hormuz, per the tracker relay ^[12].

2. The Iran-Oman Talks and the 7 Conditions

• **[NEW] Foreign Minister Araghchi:** the Sept 14 Muscat meeting will focus on a new maritime channel inside Hormuz, with Iran presenting the route map and details of its deal with Oman ^[13][3]. Araghchi stressed the Iran-Oman deal 'does not mean' Hormuz will reopen, conditioning any reopening on the US honoring the 'Islamabad Memorandum of Understanding' ^[3].
• **[NEW] Iran's 7 conditions:** Iran is demanding the US fulfill 7 conditions to reopen the Hormuz shipping corridor, per WION ^[14].
• **[NEW] Bahrain opts out:** Bahrain will not attend the Iran Hormuz meeting, per Bahrain state news agency cited in the tracker ^[12]. Source-quality note: the Bahrain no-show is single-sourced through a Chinese-language relay of state media.

3. Supply Math and Oil

• **[ONGOING] Brent > $100/bbl:** broke $100/bbl on Sept 9, with US consumers paying an estimated ~$100 billion extra for energy over the half-year conflict ^[15]. A BBC piece flags a 'huge worry' for winter heating oil and fuel costs ^[16].
• **[NEW] The Saudi pipeline is the swing factor:** the East-West pipeline (4-5 mb/d) was the main export route for the past six months while Hormuz was effectively shut, so its closure doubles the supply hit ^[5]. A single Saudi drone strike injured 2 ^[12]. The Houthis say they struck Saudi military sites with 'large numbers' of ballistic missiles and drones and that Saudi Arabia conducted 129 airstrikes on Yemen in 48 hours ^[12].

4. Contradictions and What Decides Next

• **[ESCALATED] Trump vs Iran:** 'We control the Strait of Hormuz' — yet Iran is convening channel talks and setting 7 conditions ^[12][3][14]. In the same statement, Trump said the war 'will end soon,' that Iran 'may be responsible' for the Saudi pipeline attack, and that the Houthis 'do not want to fight us' ^[12]. Print both; the contradictions are content, not noise.
• **Source quality control:** the Saudi pipeline and Iran-Oman channel details are largely single-sourced through Chinese-language relays of state media; the WANA 'two vessels' and missile lines are thinner than the Iranian media line on 1 dead. The $100 billion US consumer-cost figure rests on one People's Daily feature ^[15].
• **Falsifiable test:** a Saudi pipeline restart, an Iran-US deal on the 7 conditions, or a Houthi de-escalation at Bab el-Mandeb would each invalidate the two-chokepoint supply-shock arc. The near-term catalyst is the Sept 14 Muscat meeting ^[13][3].
