〔Overnight Brief〕US Strikes IRGC After Hormuz Shipping Attacks; Brent Clears $92, Diesel Spread Breaks $100 as Iran Fires Heavy Missiles at Jordan Marine Camp — Two Tankers Hit, Bypass Plan Pitched

0. Overnight Arc

The US opened a new front overnight: at 12 p.m. ET on Sept 1, US Central Command (CENTCOM) began strikes on IRGC targets in Iran, citing recent attempted attacks on commercial shipping in the Strait of Hormuz and against US service members in the region ^[1][2]. Iran retaliated with heavy ballistic missiles on a US Marine camp on Jordan's Gulf of Aqaba, claiming to have "destroyed several important facilities and enemy attack helicopters," while Jordan's air defense intercepted 13 incoming missiles ^[3][4]. Energy markets repriced hard: Brent cleared $92/barrel, the US diesel crack spread broke above $100/barrel, and Dutch TTF gas jumped 5.9% to €73.95/MWh, the highest since January 2023 ^[5][6]. US equities fell — Dow -0.79%, Nasdaq -1.03%, S&P 500 -0.71% ^[1].

1. Military Action and Counter-Action

• **[NEW] US strike package:** At 12 p.m. ET Sept 1, CENTCOM began strikes on IRGC targets in Iran following "recent attempted attacks by the IRGC against commercial shipping in the Strait of Hormuz and against American service members deployed to the region" ^[2]. The US has rerouted 84 commercial ships and disabled 3 to enforce a maritime blockade, per CENTCOM ^[1][7].
• **[NEW] Iranian retaliation:** The IRGC said it fired heavy ballistic missiles at a US Marine camp on the Gulf of Aqaba, claiming "massive US military casualties"; the US and Jordan have not confirmed ^[4]. Air-defense alerts were activated in Jordan's Mafraq and Aqaba provinces ahead of the strike ^[4].
• **[NEW] Air defense outcomes:** Jordan intercepted 13 ballistic missiles entering its airspace ^[3]. Iran said its new air defense system shot down a US MQ-9 drone over Khomein in Markazi Province ^[1][4].
• **[NEW] Civilian toll — single-source / unverified:** A US strike hit a wedding in Sirik, Hormozgan, killing 2 and injuring 68 ^[8][9]. Separately, the UK-based conflict monitor AirWars told AP that at least 6 weapons experts identified markings on the Lamerd strike site consistent with Lockheed Martin's new Precision Strike Missile; the US acknowledged firing Precision Strike Missiles into Iran but did not confirm the Lamerd site, and Iran said 21 civilians including 7 children were killed ^[10].
• **[NEW] Infrastructure damage:** US strikes damaged telecom and internet infrastructure in southern Hormozgan, with multiple communications towers near Sirik knocked out, per the Hormozgan deputy governor ^[11].
• **[ESCALATED] Expectation of further escalation:** House Armed Services Committee Chairman Mike Rogers said a plan is in place and the US-Iran conflict is expected to escalate further ^[12].

2. Strait of Hormuz: Shipping and Energy Corridor

• **[NEW] Tanker attacks:** Two supertankers — Saudi shipping giant Bahri's Sidr and Sinokor's Senegal Prosperity — were hit by projectiles while transiting out of the Strait of Hormuz near northeast Hasab, Oman; the UK Maritime Trade Operations independently confirmed a tanker reported three projectile hits on exit, without naming the vessel ^[6].
• **[ESCALATED] Throughput squeeze:** Iran's parliament speaker Mohammad Bagher Kalibaf said Hormuz traffic is well below the pre-conflict baseline of at least 120 ships per day and the Strait is "entirely controlled by the Iranian military"; he accused the US of lying about free passage ^[13]. The US, by contrast, claims to have rerouted 84 ships and disabled 3 ^[1][7]. Print both.
• **[NEW] Bypass plan:** Treasury Secretary Scott Bessent, speaking at a G20 fireside chat, said the Strait of Hormuz will have "bypass passage" within two years and that oil will then move via land pipelines rather than the Strait; the US plans its 3-3-3 energy program, with daily US oil production up 1.6-2.2 million barrels since Trump took office ^[14].
• **[NEW] Sanctions escalation:** Bessent said the US will announce bank sanctions this week and next, has support from the EU, ECB, UK, UAE, and Bahrain for "zero tolerance" and "economic strangulation" of Iran, and is targeting Iran-related aircraft leasing companies and British Virgin Islands accounts ^[15][14].

3. Markets: Crude, Diesel, Gas, Equities

• **[NEW] Crude and products:** Brent broke above $92/barrel in the Asia-Europe session and held above the level into the overnight print; the US diesel crack spread cleared $100/barrel; Goldman Sachs said "diesel is at the center of the supply squeeze" ^[6].
• **[NEW] European gas:** Dutch TTF near-month futures rose 5.9% to €73.95/MWh as of 9:02 p.m. Amsterdam time, the highest since January 2023 ^[5].
• **[NEW] Equities:** US stocks fell across the board — Dow -0.79%, Nasdaq -1.03%, S&P 500 -0.71%; crypto and optical communications names led losses, while healthcare led with Moderna up nearly 10% ^[1].
• **[NEW] Tankers:** Heidmar Maritime Holdings said the Q2 tanker market remained "highly volatile" on Middle East and European geopolitical tensions ^[16].

4. Diplomatic and Political Lines

• **[NEW] Russian mediation:** President Vladimir Putin met Iran's President Masoud Pezeshkian in Bishkek, said the Iran-US ceasefire is "fragile," and that Russia is providing Iran with "necessary material support"; Putin asked Pezeshkian to convey greetings to Supreme Leader Mojtaba Khamenei ^[17]. (Source is a Kremlin-website relay, not a direct read-out ^[17].)
• **[NEW] Iranian threats — single-source / unverified:** Iran's military spokesman said retaliation will be "swift, devastating, and massive" ^[18]. Iran's foreign ministry said any aggression will be met with a "decisive response" ^[7]. Iran separately threatened Bahrain and Kuwait that "gifts are on the way" ^[7].
• **[NEW] Trump's warning:** President Donald Trump said Iran will face even harsher strikes if it retaliates ^[1].
• **[NEW] US force posture — single-source social media:** Footage showed two US Black Hawk helicopters being transported on trailers near a Jordan base; analysts said this could be either preemptive relocation to avoid Iranian retaliation, or helicopters no longer flightworthy ^[19].

5. Source Quality Control

• The civilian casualty figure of 21 (including 7 children) and the Precision Strike Missile identification come from a single AP interview with AirWars plus Iranian state media; the US acknowledged firing Precision Strike Missiles into Iran but did not confirm the Lamerd site ^[10].
• The tanker names (Sidr, Senegal Prosperity) come from Greek risk firm Marisks via a Wall Street Jiànwén relay; UK Maritime Trade Operations confirmed one incident with three projectile hits but did not name the vessel ^[6].
• The "84 commercial ships rerouted, 3 disabled" is a CENTCOM count, not independently verified ^[1][7].
• The threats to Bahrain and Kuwait, and the MQ-9 shoot-down over Khomein, are single-source via Iranian state-aligned media relays ^[1][4][7].
• The Strait traffic figure of "at least 120 ships per day" pre-conflict is a Kalibaf claim, not independently confirmed ^[13].
