Strait of Hormuz

### Multiple tanker strikes

At least three separate incidents involving tankers struck by projectiles or mines occurred between Nov 2 and Nov 6, with the IRGC reporting Nov 6 that two tankers caught fire after hitting mines on unauthorised routes and one seafarer killed in an explosion on an oil products tanker.

War risk premium

### Oil volatility continues

Crude fell to a four-week low Nov 3 on expectations of a negotiated resolution, then rose more than two dollars per barrel Nov 5 as fears of renewed US military action against Iran grew.

Diplomatic track

### Talks proceed amid threats

Pakistan's Prime Minister described diplomatic efforts involving Pakistani, Iranian, Saudi, and Turkish officials as very productive Nov 4, though US President Trump stated Nov 5 he may have to destroy the rest of Iran and satellite imagery shows the USS Theodore Roosevelt moving closer to the Middle East.

SPI Marine - Strait of Hormuz attacks escalate as diplomatic talks continue

## This week: November 2-6

The Strait of Hormuz has seen a sharp escalation in attacks on commercial shipping this week, with at least three separate incidents involving tankers struck by projectiles or mines between Nov 2 and Nov 6. One seafarer was killed in an explosion on an oil products tanker, the ship's manager confirmed Nov 6, marking the week's only reported casualty among merchant crews transiting the chokepoint.

Oil markets have reacted to both the physical attacks and the diplomatic uncertainty, with crude falling to a four-week low Nov 3 on expectations of a negotiated resolution, then rising more than two dollars per barrel Nov 5 as fears of renewed US military action grew. Diplomatic efforts involving Pakistani, Iranian, Saudi, and Turkish officials continue, though US President Trump stated Nov 5 he may have to "destroy" the rest of Iran, and satellite imagery shows the USS Theodore Roosevelt moving closer to the Middle East.

This week's updates

- Nov 2 A projectile struck a ship about 9 nautical miles northeast of Lima, Oman, causing a hole in the starboard side, though the vessel and crew are safe.
- Nov 3 Oil prices fell to a four-week low as the market weighed talks to end the wars in Iran and Ukraine.
- Nov 3 An oil tanker was struck by two projectiles near the Strait of Hormuz.
- Nov 5 Oil prices rose more than two dollars per barrel over fears the US is preparing to resume military action against Iran, as attacks on tankers feed worries about oil supplies.
- FLASHNov 6 A tanker reported an explosion off Oman while transiting the Strait of Hormuz, and the IRGC said two oil tankers caught fire after being struck by mines while attempting to transit the strait using unauthorised routes.
- FLASHNov 6 A seafarer was killed in an explosion believed to have been caused by a missile attack earlier this week on an oil products tanker in the Gulf, the ship's manager reports.

Still developing

Charterers and owners moving product or chemical cargoes through the Strait of Hormuz should expect war risk premiums to firm in the near term, particularly for voyages that do not follow IRGC-designated routes. The IRGC's reference to unauthorised routes suggests enforcement of specific transit corridors, which may add delay for vessels seeking to avoid those lanes or waiting for clarification from underwriters and flag states. Owners should anticipate that some charterers may begin to price in Cape of Good Hope routing as an alternative, tightening tonnage availability for Gulf-loading stems.
