Persian Gulf Tops 2026 Cable Risk Index, Highlighting Operational Challenges for Submarine Cable Operators
The Persian Gulf has been identified as the highest-risk area in the 2026 Cable Risk Intelligence report by Starboard Maritime Intelligence. The region scored 4.6 out of 5.0 on the risk index, primarily due to geopolitical tensions, high traffic density, and limited repair access. Recent developments have exacerbated these risks, with Iran threatening to sever submarine cables in the Strait of Hormuz amid ongoing conflicts. This area is crucial as it hosts at least 17 cable systems that facilitate data traffic between Asia and Europe. The conflict has halted cable construction and repair activities, as repair ships cannot operate safely in the region. Starboard's report emphasizes the importance of early detection and risk management to prevent cable damage, using advanced monitoring technologies to identify potential threats before they materialize.
