〔Overnight Brief〕Four Tanker Strikes in 72 Hours and Houthi-Hit Aramco Sites Meet Iran's 7-Condition Ultimatum — Brent Opens +$1, G7 Readies 100m-Barrel Release

0. Overnight Arc

The shipping threat is no longer episodic. UKMTO logged four separate tanker strikes between Oct 1-4 — all on the Omani side of the strait, each hit by an unidentified projectile, with one tanker reporting engine-room damage and crew safe ^[1][2]. Brent opened Monday up $1/bbl on Houthi claims of striking Saudi Aramco ^[3]. Yet the squeeze is meeting a counter-shock: Iran's parliament speaker says Hormuz stays shut until seven conditions are met, while the G7 prepares a 100-million-barrel crude-and-diesel release and Iraq reroutes tankers around the strait ^[2][4][5][6].

1. The Shipping Strikes

• **[ESCALATED] UKMTO, Oct 1-4:** four incidents on the Omani side, each vessel hit by an unidentified projectile; one tanker reported engine-room damage, crew safe ^[1][2]. UKMTO separately reported an incident 60 nautical miles south of Yemen's Mokha port — a tanker witnessed multiple nearby explosions, crew safe, no environmental impact ^[2][7].
• **[NEW] Iraqi rerouting:** Iraq is arranging tankers to move past Hormuz ^[4][5].
• **[ONGOING] US Energy Secretary Chris Wright:** energy supply through Hormuz continues to increase ^[8]. Contradicts the closure narrative; single-source, treat with caution ^[8].

2. Iran's Conditions and the 7-Day Plan

• **[NEW] Parliament Speaker Mohammad Bagher Kalibaf:** Hormuz will not reopen until Iran's conditions are met; the US "cannot keep stalling" ^[2].
• **[NEW] Foreign Minister Abbas Araghchi "7-day plan":** if the US accepts, Hormuz reopens within seven days ^[2]. Carried via Iran's Mehr News relay — single-source, unverified.
• **[NEW] Iran's framing:** the current phase is about Hormuz, not nuclear talks; the seven prior conditions stand ^[9].
• **[ESCALATED] Lever erosion:** separate analysis argues Iran is losing some leverage over the strait ^[10].

3. The Houthi Front and the Maritime Frame

• **[NEW] Houthi claims:** ballistic-missile and drone strikes on Saudi Aramco facilities in Riyadh and Kurais, fires reported ^[2].
• **[NEW] Saudi-led coalition:** will continue full combat support to the Yemeni government to "restore the state"; spokesman Turki al-Maliki accused the Houthis of deliberately and systematically targeting Saudi civilians in Riyadh, attempting strikes on Mecca and Medina, and threatening navigation in the southern Red Sea and Bab el-Mandeb ^[11].
• **[NEW] Yemen government:** Presidential Leadership Council chairman Rashad al-Alimi said military operations have begun to retake remaining territory from the Houthis ^[12].
• **[NEW] Houthis claim Saudi airstrike on Yemen's Jawf province** ^[2].
• **[NEW] Saudi oil pipeline:** reported attacked again ^[13]. Single-source, unverified.
• **[NEW] Prime Minister Benjamin Netanyahu** at the Ashdod Naval Base: "the maritime domain has effectively become an international battlefield," visible in Hormuz and Bab el-Mandeb; Israel will not allow enemies to threaten Mediterranean sea lanes, ports, and shipping; the sixth submarine has been delivered, with more requested ^[14].

4. The Counter-Shock: Supply and Policy

• **[NEW] Brent:** opened Monday up $1/bbl on the Houthi strike report ^[3].
• **[NEW] G7:** preparing a coordinated release of 100 million barrels of crude and diesel inventories ^[6].
• **[ONGOING] US Treasury Secretary** (per Friday recap) played down concerns over rising US yields; **September nonfarm payrolls** unexpectedly missed expectations ^[6].

5. What Decides Next

• Whether Iran publicly enumerates the seven conditions and whether the US engages the "7-day plan" ^[2][9].
• Size and timing of the G7 release versus the scope of Houthi strikes on Saudi energy infrastructure ^[2][6].
• Source-quality flags: the "7-day plan," the renewed Saudi pipeline attack, and the Israeli submarine delivery each rest on a single source; the closure claim is asserted, not yet demonstrated by traffic data ^[2][13][14].
