Quick Summary

The Houthi rebels, backed by Iran, have taken control of the Red Sea coastline in Yemen, including the strategic island of Perim, which is located in the Bab el-Mandeb Strait. The capture of these areas has raised concerns about a return to all-out war in Yemen and poses a threat to global oil supplies. If the Houthis can successfully threaten shipping along this key waterway, it could lead to reduced oil exports through another major route, exacerbating the world's energy crisis. Oil prices have already risen above $100 per barrel for the first time since May, amidst these developments.

Story summary

Yemen's Houthi rebels captured the port city of Mokha and advanced towards strategic locations in the Bab el-Mandeb Strait. This includes reaching Perim island, tightening their control over vital shipping routes that connect the Red Sea to the Gulf of Aden. The capture potentially disrupts maritime trade and increases threats to energy markets, as these straits are crucial for global oil transportation. Saudi Arabia has seen its crude supply fall significantly due to disruptions in the Bab el-Mandeb Strait by Houthi groups. Full control over this strategic waterway could give Iran a significant advantage against the U.S., reducing critical transit corridors and causing oil prices to surge. The Yemeni government, backed by Saudi Arabia, has retreated from several coastal towns towards Dhubab, overlooking the strait, while engaging in airstrikes on Houthi positions. International observers fear escalating conflicts might renew an all-out civil war in Yemen. Smoke detected near Saudi's East-West oil pipeline further complicates regional stability and energy security concerns. These developments raise alarms about global economic impacts, particularly concerning inflation and supply chain disruptions. The U.S., as a close ally of Saudi Arabia, is closely monitoring the situation, wary of potential escalations that could draw it deeper into conflict with Iran-backed Houthi rebels.
