Houthi militant group targets Saudi Arabian supertanker in Red Sea

Yemen’s Houthi militant group claimed responsibility for launching ballistic missile strikes against the Saudi oil tanker Wafa near Yanbu and another tanker named Daisy in the Gulf of Aden on August 5. The attacks mark the latest escalation in what the Iran-aligned group has framed as a full naval blockade of Saudi maritime operations, declared on July 20.

Brent crude prices responded almost immediately, rising approximately 1% to around $80 per barrel.

A blockade by another name

Spokesman Yahya Saree announced the strikes as part of the group’s stated “siege for a siege” doctrine, positioning the attacks as retaliation for Saudi Arabia’s broader maritime operations in the region.

Earlier in July, the group claimed missile strikes on three other tankers: the Encelia, the Layla, and the NCC Ghazal. None of those incidents resulted in confirmed major spills or casualties, though independent verification of the Houthis’ claims has remained limited across all attacks.

The UK Maritime Trade Operations (UKMTO) has reported related incidents involving explosions and fires near tankers in the Gulf of Aden and Red Sea. In monitored cases, crews have been reported safe.

Some Saudi-linked vessels have already begun altering their courses through the Gulf of Aden and Red Sea to avoid potential strikes.

Why the Red Sea matters for oil markets

The Bab el-Mandeb strait, the narrow passage connecting the Red Sea to the Gulf of Aden, is one of the world’s most critical maritime chokepoints. Millions of barrels of crude and refined petroleum products transit through it daily.

Rerouting vessels around the Cape of Good Hope instead of through the Red Sea adds weeks to delivery times for crude heading to Europe and North America.

Geopolitical escalation with economic consequences

Iran’s relationship with the Houthis adds another layer of complexity. The group’s access to increasingly sophisticated missile and drone technology has long been attributed to Iranian support.

Each successful or even attempted strike on a Saudi tanker increases the risk premium embedded in oil prices. If the Houthis demonstrate the ability to consistently threaten vessels near Yanbu, one of Saudi Arabia’s key oil export terminals on the Red Sea coast, markets will need to price in a more permanent disruption scenario.
