This study aims to explore the dimensions of the intersection between traditional geopolitics and cybersecurity, focusing on the Strait of Hormuz not only as a vital chokepoint for global energy supplies but also as a digital backbone and critical infrastructure through which major submarine internet cables pass, connecting the Arabian Gulf with Asia and Europe. The study addresses a core problem: the vulnerability of global digital dependence on maritime corridors located in high-stakes geopolitical conflict zones, and the attempts by regional powers, such as Iran, to impose legal and technical sovereignty over this international infrastructure as a tool for strategic leverage. Utilizing the “Comparative Approach,” the “Systems Analysis Approach,” and “Geopolitical Analysis Tools,” the study examines the economic impact of undersea cable disruptions during crises. This impact extends beyond standard service outages to disrupting digital supply chains, increasing the costs of alternative capacities and insurance, and elevating latency in financial markets. The study concludes that the potential disruption of cables in the Strait of Hormuz serves as a complex strategic blackmail tool equivalent to a traditional naval blockade. It recommends accelerating the development of alternative land and sea routes via other regional corridors to mitigate total reliance on the Strait.
