Digital Chokepoints: Iran's Bid for Control Over the Strait of Hormuz Undersea Cables
The Strait of Hormuz has long been recognized as one of the world's most critical chokepoints for global oil shipments. However, a new development suggests that this strategic waterway is becoming equally vital—and vulnerable—for the digital age. Iran is currently mulling a plan to take full control of the seven undersea internet cables that traverse the strait, potentially transforming a physical transit route into a digital power lever.
These fiber-optic cables are the backbone of the modern internet, carrying approximately 99% of global data traffic. In the Strait of Hormuz, these cables facilitate a massive share of the data flow between Europe, the Gulf states, and Asia, supporting everything from cloud services to international banking and diplomatic communications.
A New Model of Digital Governance
According to reports from the FARS News Agency, Tehran is proposing a governance model that would fundamentally change how these cables are managed. The proposed requirements include:
- Permits and Tolls: The passage of submarine cables would require an official permit and the payment of transit tolls.
- Legal Jurisdiction: Foreign companies operating these cables would be required to operate under Iranian laws.
- Domestic Maintenance: Iran seeks to ensure that all management, repair, and maintenance of these cables are entrusted exclusively to domestic Iranian companies.
By implementing these measures, Iran aims to leverage its geographic position to exert influence over global data traffic and generate revenue from the infrastructure that connects the East and West.
Strategic Implications and Risks
This move is not merely about revenue; it is about strategic leverage. The Islamic Revolutionary Guard Corps (IRGC) has previously issued warnings that it could target submarine cable infrastructure used by Gulf states. By formalizing control through a "governance model," Iran effectively creates a legal framework for what some observers describe as a form of digital extortion.
The "Piracy" Perspective
Technical and geopolitical observers have raised concerns that this proposal is less about administration and more about coercion. As one commentator noted:
"By 'control' Iran doesn't mean they will operate or maintain these cables. They mean 'pay up, or we'll destroy these cables when we feel like it'. Modern day piracy."
The Risk of Global Precedent
There is also a broader concern that if Iran successfully imposes tolls on international waters, it could trigger a domino effect. If other nations with strategic maritime chokepoints—such as Indonesia with the Strait of Malacca—follow suit, the cost of global connectivity would rise, and the risk of conflict would increase.
"That creates the problem that if Iran is allowed to do this, other countries will do this too... a lot of countries will give very serious thought to attacking each other... and may decide they don't have a choice."
The Technical Counter-Response
From a network engineering perspective, the move may be counterproductive for Iran. The internet is designed to be resilient and reroutable. If a specific path becomes too expensive or politically unstable, traffic is typically diverted to alternative routes.
Critics argue that by attempting to monopolize these cables, Iran risks having its own connectivity marginalized. If global operators decide to route traffic around the Strait of Hormuz to avoid Iranian tolls and interference, Iran could find itself digitally isolated, with its own connections cut by adversaries or bypassed by the market.
Conclusion
The proposal to control the undersea cables of the Strait of Hormuz highlights the increasing intersection of physical geography and digital infrastructure. As data becomes as valuable as oil, the struggle for control over the "pipes" that carry it will likely become a central theme in 21st-century geopolitics.
