Digital ‘catastrophe’?: Iran now eyes internet cables beneath Hormuz

## Iran's New Target: Subsea Internet Cables

Iran has signaled potential threats to subsea internet cables in the Strait of Hormuz, a critical passage for global data traffic. This move could disrupt digital communications between Europe, Asia, and the Gulf, raising fears of a significant digital impact.

## Strategic Waterway at Risk

Iranian officials have suggested imposing fees on submarine cables passing through the strategic waterway. Companies that do not comply might face disruptions, marking an escalation in Tehran's tactics amid ongoing tensions.

## Global Implications

Subsea cables are vital for internet and data traffic, handling nearly all global communications. Damage to these cables could affect banking, cloud services, and communications across continents. Experts warn of potential widespread disruptions if Iran follows through with its threats.

## Historical Context

The Strait of Hormuz is a crucial digital corridor linking Asia and Europe. Previous incidents, like the 2024 cable disruptions in the Red Sea, highlight the potential for significant regional and global impacts.

## Legal and Security Concerns

While Iran cites international maritime law to justify its actions, experts argue that the legal basis is questionable. The Strait of Hormuz is governed by international law, unlike the Suez Canal, which is fully controlled by Egypt. Security analysts also note that Iran's military capabilities could pose a threat to underwater infrastructure.

## Potential Economic Impact

Disruptions could affect countries across the Gulf and beyond, impacting internet services, financial transactions, and cloud-based operations. The situation underscores the strategic importance of the Strait of Hormuz in both energy and digital domains.
