The Houthis have struck Red Sea vessels repeatedly, but coalition escort vows and de-escalation leave markets leaning toward no confirmed hit by July 31.
The Houthi movement declared a naval blockade against Saudi Arabia on Monday, July 20, 2026, ordering commercial vessels to turn back from Saudi ports and warning shipping companies not to load or discharge cargo there. The Iran-aligned group framed the blockade as retaliation for Saudi military actions, marking a significant escalation of its maritime campaign around the Bab al-Mandab Strait, the chokepoint linking the Red Sea to the Gulf of Aden. In an email to shipping firms, the militia said "vessels are banned from loading or discharging cargo at or from any Saudi ports" and that non-compliant ships "may be targeted." The move opens a potential new front in the wider war with Iran and raises the threat to global energy supplies. The question of whether the houthis successfully target shipping by july 31, 2026 turns on whether these threats translate into strikes. [Marine News Magazine, Jul 21]
The escalation follows Iranian pressure. Two senior Iranian sources and a regional source told Reuters on July 16 that Iran asked the Houthis to prepare to attack Red Sea shipping if the United States expands airstrikes to Iranian energy infrastructure. A source close to the group said the Houthis had completed preparations by deploying missiles and drones near the strait. Whether the houthis successfully target shipping by july 31 may therefore hinge on U.S. decisions about striking Iran's power network. [The Jerusalem Post, Jul 16]
Notably, the Institute for the Study of War reported it had recorded no Houthi attacks on shipping since July 7, 2025, though the group ordered Saudi-bound vessels to turn back by radio on July 20. A Saudi-led coalition vowed to protect commercial ships transiting Bab al-Mandab. Analysts warn the blockade will almost certainly raise Red Sea shipping costs by deterring transits, even absent kinetic strikes — leaving open whether the houthis successfully target shipping by july 31, 2026.
