Tankers Alter Red Sea Routes Following Houthi Threats Against Saudi-Calling Vessels

## Tankers Alter Red Sea Routes Following Houthi Threats Against Saudi-Calling Vessels A number of tankers have changed course in the Red Sea after loading cargo in Saudi Arabia, according to Seatrade Maritime, as Houthi militants escalate threats against vessels associated with Saudi port calls. The course reversals signal a renewed phase of disruption in the Red Sea, a critical artery for global energy trade that has been under sustained pressure since Houthi forces began targeting commercial shipping in late 2023. The latest development suggests the Iran-backed group is expanding the scope of its targeting criteria to include vessels that have called at Saudi ports — a significant escalation that could affect a broader segment of the tanker fleet operating in the region. ### Implications for Energy Shipping Saudi Arabia is one of the world's largest crude oil exporters, and tankers regularly load at terminals including Ras Tanura and Yanbu before transiting the Red Sea toward the Suez Canal and onward to European and Asian markets. Any sustained pattern of threats or attacks against Saudi-loading vessels would place additional pressure on shipowners and operators to reroute around the Cape of Good Hope — a detour that adds approximately 10 to 14 days of sailing time and significantly increases voyage costs. The Red Sea crisis has already prompted widespread rerouting since late 2023, with major container lines and tanker operators diverting vessels away from the Bab el-Mandeb Strait. The additional threat layer targeting Saudi-associated tankers could further reduce traffic through the corridor and tighten available tonnage in the region. ### Operator and Market Response Shipowners and charterers will be closely monitoring the situation as they assess war risk insurance premiums and voyage planning for the region. The development is likely to prompt renewed guidance from flag states, P&I clubs, and industry bodies regarding safe transit protocols in the southern Red Sea. The Houthi campaign against commercial shipping has drawn international naval responses, including Operation Prosperity Guardian led by the United States, though attacks have continued despite these efforts. Industry stakeholders are advised to monitor official advisories from naval coalition forces and consult with their insurers and security advisors before committing to Red Sea transits involving Saudi port calls. *Source: Seatrade Maritime*
