What changed since chapter 25

Since chapter twenty-five, the US struck Iran near the strait, Iran's Guards claimed tanker mine strikes on three more days, and UKMTO logged new attacks off Oman, Saudi Arabia and Qatar. [5, 8, 9, 7, 10, 15]

President Donald Trump confirmed that the US struck Iran early on Tuesday 3 November, calling it a 'minor attack' on an anti-aircraft facility, Al Jazeera reported. Iranian media said the strikes hit Qeshm Island, near the strait. US officials told US media the strikes were 'defensive' and followed Iranian fire at an American aircraft, Al Jazeera said. [5, 6]

The Guards' navy said on Sunday 1 November that two tankers 'exploded' after striking mines on an 'unauthorised route', Middle East Eye reported from state media. On Wednesday 4 November the Guards said four 'non-compliant' tankers were destroyed by mines south of the strait and two more vessels halted, AFP reported through Gulf News. On Thursday 5 November they said tankers and a tugboat caught fire on an unauthorised route, Al Jazeera reported. [8, 9, 6, 7]

The record

The Joint Maritime Information Center's Update 110, covering 1 March to 1 November, keeps the strait at SEVERE, with deliberate attacks 'highly likely'. It counts 18 confirmed attacks in the strait since 6 October and 167 incidents of all kinds across the region since 1 March. It names the RITI, LOUISE 1 and ARZANAH as tankers attacked in the strait on 28 and 29 October. [1]

About 490 vessels were waiting outside the strait on 1 November, against single-digit to low double-digit transits a day visible on ship tracking, the center said. US-facilitated transits from 29 to 31 October numbered 119, against a 2025 average of about 138 vessels a day. Its count of tankers sailing without US help shows none on Tuesday 27 October and four on Saturday 31 October. [1]

UKMTO issued Warning 191-26 on Sunday 1 November after a Mayday from a ship struck by an unknown projectile in the strait, gCaptain reported. Late that day two projectiles hit a tanker about 72 nautical miles east of Ras Al Khafji, Saudi Arabia, with all crew accounted for. On Tuesday two projectiles struck a tanker's engine room about 14 nautical miles northeast of Limah, Oman, Al Jazeera reported UKMTO saying. [10, 5]

UKMTO reported on Thursday 5 November that two projectiles hit a tanker about 50 nautical miles north of Madinat ash Shamal, Qatar, at 2320 UTC on Wednesday, Siasat reported. The crew's condition and the damage were unknown. Al Jazeera said it could not be verified whether the Limah attack was linked to the Guards' four-tanker claim. [15, 5]

Qatar's foreign ministry on Sunday 1 November condemned the attack on the LNG carrier Al Mayeda, owned by Nakilat, struck on Friday 30 October. Pakistan had negotiated safe passage for the ship with Iran, and Iran gave a green light hours before, people with direct knowledge told Bloomberg. Nakilat said there were no injuries and the carrier remained operational. [10, 11, 16]

Mohsen Rezaei, secretary of Iran's Supreme National Security Council, said on Tuesday the US reply to Iran's seven conditions was 'not convincing', Al Jazeera reported. Iran's foreign ministry said the plan was condensed to run within two days, and Reuters described it as ending the US blockade and reopening the strait. Trump told the Financial Times the US seemed to be getting everything it wanted and had no immediate plans to strike, Bloomberg reported. [5, 12, 14]

The Energy Information Administration's Short-Term Energy Outlook of October assumed Middle East flows stay constrained through the fourth quarter, with convoys and bypass routes lifting exports. It forecast Brent at an average of $105 a barrel in that quarter, from inputs finalized on 1 October. Brent fell below $100 on Wednesday 4 November for the first time since early October, AFP reported through Gulf News. [2, 6]

Who it reaches

Scorpio Tankers (STNG) is adjacent: its third-quarter release says the conflict 'kept the global fleet dislocated', and its LR2 tankers earned $55,184 a day in the quarter. Frontline (FRO) is adjacent: its second-quarter report said risk across Hormuz and the Red Sea was 'rapidly changing with little warning'. Qatar's LNG trade is reached directly through the Al Mayeda; Nakilat has no US listing. [3, 4, 10]

Where the sources disagree

The Guards call the strikes mine hits; a US official told Bloomberg no ship has struck a floating mine while transiting the strait. The attacks the center named were by projectile, and on the LOUISE 1 by two explosive devices a small boat attached to the hull. [13, 1]

Al Jazeera reported the Guards' Thursday statement as three tankers and a tugboat on fire; Siasat, citing Fars, reported two tankers and a tugboat. Bloomberg reported shipments through the strait at about 80 percent of prewar levels, while the center counts single-digit daily transits of ships sailing without US help. [7, 15, 13, 1]

What settles it next

The EIA publishes its next Short-Term Energy Outlook on Tuesday 10 November. Qatari officials expected feedback from both sides on new proposals, and new members of Congress take office in early January, Bloomberg reported. US officials told Axios the military is finishing preparations for possible major combat, which is not an order, Gulf News reported. [2, 14, 6]
