On July 20, Yemen’s Houthi movement announced a naval blockade of Saudi Arabia, accusing the kingdom of exploiting Yemeni oil resources. The Saudi-led coalition stated on July 21 that it had begun protective measures for commercial vessels in the Bab el-Mandeb Strait and described the Houthi actions as piracy.
An International Crisis Group analyst assessed that disruptions to routes including the East-West pipeline and Bab el-Mandeb could raise Saudi security costs and affect global energy supplies if extended to the Strait of Hormuz.
