The Digital Choke Point: Undersea Cable Risks in the Strait of Hormuz

As of April 23, 2026, the Strait of Hormuz is no longer just a vital artery for the world’s oil supply. It has emerged as a critical “digital choke point,” with recent intelligence reports flagging severe risks to the undersea internet cables that facilitate communication between Asia, the Middle East, and Europe. While the world has long monitored the Strait for its impact on energy prices, the vulnerability of the global internet infrastructure is now taking center stage in international security discussions.

A Vulnerable Web Beneath the Waves

Undersea cables are the unsung heroes of the modern age, carrying over 95% of international data traffic. In the Persian Gulf region, these cables are densely packed within narrow corridors, making them susceptible to both accidental damage and intentional disruption.

The impact of a major disruption in the Strait of Hormuz would be catastrophic for the regional economy. The following chart illustrates the estimated share of regional internet traffic that relies on these specific undersea routes.

Global Repercussions of a Regional Cut

Experts warn that a coordinated effort to sever cables in the Strait of Hormuz could knock out significant portions of the global internet’s backbone. It is estimated that approximately one-fifth of all global internet traffic passes through or near this region at some point in its journey.

Conclusion

The situation in the Strait of Hormuz serves as a stark reminder of the physical reality of our digital world. We often think of the internet as a “cloud,” but it is actually a network of physical wires susceptible to physical threats. As we move deeper into 2026, the resilience of these connections will likely define the economic and political landscape of the next decade.
