Iran is weaponising the world’s hidden digital chokepoint

Iran’s threats to the Strait of Hormuz should be understood as more than another round of brinkmanship over shipping lanes.

They point to a broader geopolitical shift: power in the Middle East is increasingly being exercised not just through missiles, mines and tankers, but through the hidden infrastructure that keeps modern economies running. Under the sea, fibre-optic cables carry the digital traffic of finance, trade, diplomacy and intelligence. That makes Hormuz not only a maritime chokepoint, but a data chokepoint too.

For decades, the world has treated the Strait of Hormuz as a passageway for oil. That remains true: roughly one-fifth of global petroleum liquids pass through it, which is why every crisis in the Gulf sends energy markets into a nervous spasm. But the strait’s strategic meaning has widened. Subsea cables now run through nearby waters, linking the Gulf to Asia and Europe and giving the region’s economies access to the internet backbone on which banking, logistics, cloud computing and government systems depend.

The vulnerability is obvious once you look for it, which is precisely why it has been so easy to overlook.
That is what makes Iran’s posture so consequential. Tehran has spent years learning how to weaponise geography. In the past, that meant harassing tankers, seizing ships, or threatening to close Hormuz outright. Now the target set is broader. If the sea lanes are the economy’s bloodstream, the cables are its nervous system. Disrupt one and you create panic; disrupt both and you compound uncertainty.

Even without cutting a single cable, the mere suggestion that Iran might do so can raise risk premiums, unsettle investors, and force governments and companies to think about worst-case scenarios they previously filed under theoretical.
This is not just about technical damage. It is about strategic signalling. Iran does not need to sever every cable to gain leverage.

It only needs to convince its rivals that it can. In a region where perception is often as powerful as hardware, that is enough to alter behaviour. Gulf states depend heavily on stable digital links for finance, state administration, aviation, energy, and the data-heavy economies they are trying to build. The prospect of even temporary disruption introduces a new layer of pressure on governments already trying to manage conflict, deterrence and domestic expectations at once.

The wider danger is that the Strait of Hormuz becomes a model for future coercion. If one state can threaten subsea cables in a global chokepoint, others will study the lesson. The oceans are full of hidden infrastructure, and many of those systems are poorly defended, hard to repair and difficult to monitor at scale. That is a structural weakness in the architecture of globalisation. The world built a hyperconnected economy without giving enough thought to how fragile the physical layers beneath it really are. The result is that a crisis in one narrow waterway can ripple far beyond the region, affecting everything from payment systems to satellite coordination to the timing of container shipments.

The geopolitical implications are particularly severe because the Persian Gulf is already one of the world’s most militarised theatres. A move against subsea cables would blur the line between conventional conflict, economic warfare and cyber operations. It would also widen the circle of stakeholders. Europe, Asia and the United States all have an interest in keeping Hormuz open, not only for energy flows but for digital continuity.

That means any escalation could draw in outside powers more quickly and with less warning than in previous crises. A cable attack would not be a local incident; it would be read as a challenge to the stability of the global system itself.
There is also a dangerous asymmetry at work. Iran can create disruption relatively cheaply, while repair, rerouting and resilience cost others far more. A navy can escort tankers, but it cannot instantly protect every stretch of seabed. Cable repair ships are few.

Permits, access and security all slow recovery. That asymmetry is exactly why the threat matters. In modern geopolitics, the side that can create uncertainty faster than its opponents can restore order often gains the upper hand, even without winning a battle in the traditional sense.
The lesson for the West and its Gulf partners is uncomfortable.

Deterrence in the 21st century cannot be confined to missiles and minesweepers. It must extend to the physical infrastructure of connectivity: redundant cable routes, faster repair capacity, stronger monitoring, and closer coordination between governments and private operators. Yet even that is only partial insurance. Because the deeper issue is not simply vulnerability, but interdependence. The global economy has become so dependent on a handful of narrow passages, both maritime and digital, that regional conflict now has systemic consequences.

Iran understands this. By turning the world’s attention to the undersea cables beneath Hormuz, it is reminding its adversaries that power in the age of networks is exercised in layered ways. Control the sea, and you influence oil. Threaten the seabed, and you unsettle data, finance and communication. The real risk is not that Iran will literally unplug the internet, but that it will exploit the fragility of the infrastructure on which the world’s confidence depends.

That is the geopolitical message of Hormuz now: the age of chokepoints is not over. It has simply gone underground.
