Houthis reportedly advance to key Red Sea island, further threatening crucial oil choke point

The Iran-backed Houthis reportedly advanced to Yemen’s strategic Perim Island on Friday, delivering a major boost to the militant group’s push to take control of one of the world’s most important shipping choke points.

The capture of Perim Island, which was reported by several news agencies, citing multiple Yemeni government sources, comes just one day after the Houthis seized Yemen’s port city of Mokha on the Red Sea coast. CNBC could not independently confirm the report.

The rapid ground offensive is seen as a severe setback to Saudi Arabia and the Yemeni forces it backs and puts Iran and its proxies on course to exercise control over two critically important oil choke points on either side of the Arabian Peninsula: the Bab el-Mandeb Strait and the Strait of Hormuz.

Perim Island is a small and rocky area of land that divides the Bab el-Mandeb Strait, a waterway that connects the Red Sea to the Gulf of Aden and to global markets.

There are concerns that the Houthis advance toward the Bab el-Mandeb Strait could have significant ramifications for global trade, particularly if the militant group ratchets up threats or attacks on Red Sea shipping.

Indeed, the capture of Mokha marked a “major blow” to Saudi Arabia as it raises the possibility of the group exerting a tighter grip on the Bab el-Mandeb Strait, according to Hamish Kinnear, principal Middle East and North Africa analyst at risk intelligence company Verisk Maplecroft.
