Iran has raised alarms regarding the vulnerability of submarine cables in the Strait of Hormuz, critical for the region’s digital economy, amid fears of potential attacks on essential infrastructure. This narrow waterway, already a vital route for global oil shipments, also hosts several fiber-optic cables that link countries from Southeast Asia to Europe. Subsea cables are responsible for about 99% of the world’s internet traffic and play a crucial role in telecommunications and cloud services. Disruptions to these cables could result in significant slowdowns or outages for online services and e-commerce, impacting financial transactions and economic stability. Despite ongoing regional conflicts, including the war in Iran, which have affected other infrastructures, undersea cables have remained intact so far.
Why It Matters
The Strait of Hormuz is a strategically significant chokepoint, with major cables such as Asia-Africa-Europe 1 and the FALCON network facilitating global connectivity. While the total length of submarine cables has increased, faults remain stable, primarily caused by human activities like fishing and ship anchoring. The geopolitical landscape has intensified risks of sabotage, particularly in conflict zones, complicating repairs and maintenance of these cables. Historical incidents, such as damage caused by vessels during military operations, highlight the critical need for safeguarding these networks to ensure uninterrupted global communications and economic operations.
