Red Sea: ban, attacks, declared blockade

From the ban on Israeli ships to the Bab el-Mandeb blockade, two months on the southern corridor — and the rerouting it forces. Every event is dated, sourced and linked to its original articles.

Chronology

Jul 27

Red Sea traffic slows — yet Saudi crude keeps moving

Transit data show a slowdown after the attack on Saudi Arabia, while enforcement stays selective: Saudi crude is still moving. A measure of the gap between a declared blockade and an enforced one — the gap a chartering plan turns on.

Jul 22

Blockade declared on the Bab el-Mandeb strait

The Houthis extend the blockade to the strait itself — the neck through which most Asia–Europe traffic passes on its way to Suez. Washington plays the threat down; the chartering market rather less.

Jul 20

Houthis declare a naval blockade against Saudi Arabia

Sanaa announces a maritime blockade aimed at Saudi Arabia. The escalation changes target: from a flag to an energy-exporting state, which puts volumes rather than individual ships at stake.

Jul 5

Cargo ship attacked in the Red Sea off Yemen

A merchant vessel reports an attack, confirmed by the UK maritime authority. The move from declaration to act: from here, exposure stops being contractual and becomes operational.

Jun 10

Suez picks up tanker traffic diverted from Hormuz

The Hormuz shutdown pushes crude cargoes towards Suez. A measurable rerouting effect: a blocked strait does not remove traffic, it concentrates it on the neighbouring corridor — whose risk then becomes yours.

Jun 8

Houthis declare a total ban on Israeli ships

Sanaa bars all Israel-linked navigation in the Red Sea. A declaratory ban, but it redefines the risk test: what is targeted is no longer the route but the flag and the ownership.

Comparable precedents

Houthi campaign, 2023–2024The mass diversion round the Cape added 10–14 days to Asia–Europe transit and raised war-risk premiums by an order of magnitude. The dominant cost was not spot freight but the working capital tied up in longer voyages.
Ever Given blockage, 2021Six days of Suez closure was enough to disorder container rotations for months. A reminder that the length of an interruption is a poor predictor of the length of its effects.

Methodology — Events detected continuously across thousands of sources (GDELT + press feeds), grouped into deduplicated situations. Corroboration counts independent originators: syndicated copies of one wire story are merged, so the figure shown is not a raw outlet count. The intensity curve measures our own ingestion on this topic.
