Houthis said on July 20, 2026, that they were imposing a maritime blockade against Saudi Arabia, a move that quickly disrupted traffic in the Red Sea. According to the report, the embargo targets Saudi vessels at the Bab al-Mandab Strait, a strategic chokepoint for global energy shipments.

The announcement appeared to have an immediate effect on shipping activity, with tankers turning back rather than continuing through the area. That shift highlighted how quickly security threats in the Red Sea can alter commercial decisions and force route changes for vessels carrying key cargoes.

Oil markets were rattled by the development, with concerns that the disruption could tighten supplies and push crude prices above $100. Even without a full halt to regional exports, the risk of interrupted transit through a major maritime corridor can add pressure to energy prices and shipping costs.

The situation also underscores the growing complexity of navigation in the Red Sea. As operators reassess routes in real time, the blockade threat is adding fresh uncertainty for traders, shippers and energy markets already sensitive to disruption around the Bab al-Mandab Strait.
