Description
The Strait of Hormuz has long been recognized as a critical maritime chokepoint for global oil supplies, with approximately 20% of the world's petroleum transiting its narrow waters. However, a parallel and arguably more consequential vulnerability has remained largely absent from scholarly and policy discourse: the concentration of undersea fibre-optic telecommunications cables traversing this same waterway. These cables carry approximately 95% of intercontinental internet traffic, underpinning global financial systems, cloud infrastructure, government communications, and digital commerce. This study conducts a critical analysis of the undersea cable infrastructure in the Gulf region, mapping the concentration of cables passing through the Strait of Hormuz and assessing the geopolitical, economic, and cybersecurity implications of this hidden vulnerability. Employing a qualitative analytical approach grounded in critical infrastructure studies, international relations theory, and geopolitical analysis, the paper examines the dual risks of intentional targeting and accidental disruption of these cables. It argues that the Strait of Hormuz constitutes not only an oil chokepoint but also a "data chokepoint", which is a concentration of information infrastructure whose disruption would have cascading consequences for global digital connectivity, financial stability, and international security. The study contributes to emerging scholarship on critical infrastructure protection, maritime security, and cyber-geopolitics by highlighting a vulnerability that has been systematically overlooked in favour of more visible energy security concerns. The paper concludes with policy recommendations for diversifying cable routes, enhancing physical protection mechanisms, and developing international frameworks for undersea infrastructure protection.

- Appendix A: Map of Undersea Cables in the Gulf Region (Description)
- Figure A1: Undersea Cable Network of the Gulf Region
- The Gulf region's undersea cable network comprises approximately 25 active systems connecting the Arabian Peninsula to East Africa, India, Southeast Asia, and the Mediterranean. Key features:
- Cables enter the Gulf through two primary corridors in the Strait of Hormuz: the western corridor through Omani waters near the Musandam Peninsula, and the central corridor through international waters.
- Major landing points: Muscat and Salalah (Oman); Fujairah, Dubai, and Abu Dhabi (UAE); Jeddah and Dammam (Saudi Arabia); Doha (Qatar); Manama (Bahrain); Kuwait City (Kuwait); Bandar Abbas (Iran).
- East-West routes: Cables from Europe and the Mediterranean connect to the Gulf via Egypt and the Suez Canal corridor, then traverse the Red Sea and the Gulf of Aden before entering the Gulf through the Strait of Hormuz.
- North-South routes: Cables from India and Southeast Asia connect directly to the Gulf, with some traversing the Arabian Sea to Oman and the UAE.
