Houthis have disrupted but never fully closed Bab el-Mandeb; a full shutdown by August 31 stays unlikely at 82% NO.
Tensions across the Middle East's maritime chokepoints escalated sharply in mid-July after Iran, having already choked off shipping through the Strait of Hormuz, began signaling it could order Yemen's Houthi allies to shut the Bab el-Mandeb gateway to the Red Sea. Analysts described the move as Tehran's "nuclear option," extending disruption beyond the Gulf to a second vital energy artery. With Hormuz closed and the United States reimposing a naval blockade of Iranian ports, any Houthi action against Red Sea traffic would leave the region's two main oil-export routes disrupted simultaneously, opening a new front against Washington. The question of whether the Bab el-Mandeb strait effectively closed by August 31 hinges directly on this escalation path. [Times of Israel, Jul 14]
On July 16, Reuters reported that Iran had formally asked the Houthis to stand ready to close the strait if the US followed through on President Donald Trump's threat to strike Iranian power plants and bridges. A source close to the group said the Houthis had completed preparations, deploying missiles and drones near Bab el-Mandeb in Yemen's highlands overlooking Hodeidah and the Gulf of Aden, and were awaiting the order to begin. Days earlier, a container ship was attacked off the coast of Oman, prompting the UK to raise the regional threat level to "severe" and the IMO to suspend its vessel evacuation initiative.

Whether the Bab el-Mandeb strait effectively closed by August 31 now depends on the US-Iran confrontation. Iran's Islamic Revolutionary Guard Corps vowed to keep Hormuz shut until "the end of America's evils" and threatened to block "all other export corridors" benefiting the US and its allies. Tehran warned that if Trump's threats are executed, "all regional infrastructure will be destroyed." A Houthi blockade remains conditional and reversible, but staged military readiness near the passage marks a significant shift, keeping the near-term risk to global trade and energy supplies elevated through the summer.
