India’s Digital Lifeline at Risk as West Asia War Escalates

The war in West Asia, now stretching beyond a month, has begun to cast shadows far beyond the battlefield. While missiles, troops, and oil dominate headlines, another front is quietly emerging—one that could strike at the very heart of India’s economy and daily life: the threat of internet disruptions caused by damage to submarine cables in the Red Sea.

The fear is not unfounded. Nearly 95 percent of global international data flows through undersea fibre optic cables, and the Red Sea is one of the most critical chokepoints in this network. India, with its rapidly digitising economy, is particularly vulnerable. The September 2025 incident, when a commercial ship’s anchor severed multiple cables, offered a grim preview. Though services did not collapse entirely, India experienced outages, latency, and congestion across major networks. That was an accident. Today, the possibility of deliberate sabotage looms large.

Iran-backed Houthis have repeatedly threatened to cut cables in the Red Sea, and with the U.S.-Israel war against Iran escalating, such threats carry weight. The International Cable Protection Committee has long warned that dragged anchors account for about 30% of annual cable incidents, but deliberate attacks would be far more devastating. Unlike accidental damage, targeted strikes could cripple multiple cables simultaneously, leaving nations scrambling for connectivity.

For India, the stakes are enormous. The country hosts 17 international cables across 14 landing stations, with Mumbai and Chennai serving as the two primary gateways. This uneven distribution is a structural weakness: two-thirds of traffic flows through Mumbai, while the rest is routed via Chennai. If either hub were compromised—whether by conflict spillover, technical failure, or sabotage—the ripple effects would be immediate and severe.

India’s dependence on digital infrastructure has deepened dramatically in recent years. Cloud services underpin businesses, digital payments drive commerce, and artificial intelligence workloads increasingly rely on seamless connectivity. A disruption in the Red Sea cables would not merely slow down video calls or email exchanges; it could paralyse financial transactions, destabilise stock markets, and interrupt critical services from healthcare to logistics. In a nation where UPI transactions cross billions monthly, even a few hours of outage could translate into massive economic losses.

The geopolitical angle is equally troubling. The Red Sea and Strait of Hormuz are already volatile zones, with oil tankers and naval deployments crowding the waters. Adding submarine cables to the list of potential targets raises the spectre of hybrid warfare—where economic disruption becomes as potent a weapon as missiles. For India, which imports significant energy from the region while exporting IT services globally, the double blow of oil shocks and internet cuts would be crippling.

India’s vulnerability is compounded by its uneven preparedness. While the country has invested in expanding cable networks, redundancy remains limited. Unlike Europe or the U.S., which enjoy multiple alternative routes, India’s reliance on a handful of chokepoints leaves it exposed. The September 2025 incident showed that rerouting traffic through alternative paths is possible but slow, costly, and insufficient to handle peak demand.

The economic consequences of a deliberate cable cut would be staggering. Cloud-dependent industries like fintech, e-commerce, and AI startups would face immediate disruption. International clients relying on India’s IT services could see delays, eroding trust in India’s digital reliability. Stock markets, already sensitive to geopolitical shocks, could tumble further if connectivity falters. Even ordinary citizens would feel the pinch—digital payments failing at shops, streaming services collapsing, and communication lines breaking down.

Diplomatically, India faces a dilemma. While it has maintained a cautious stance in the U.S.-Israel-Iran conflict, the threat to submarine cables forces New Delhi to consider proactive measures. Strengthening naval presence in the Indian Ocean, collaborating with global cable protection initiatives, and diversifying digital routes are urgent priorities. Yet these require coordination with multiple stakeholders—governments, private telecom operators, and international bodies—at a time when global trust is fraying.

The larger question is whether India can insulate itself from the fallout of wars it is not directly part of. The answer, for now, is sobering. In a hyper-connected world, geography offers no refuge. The Red Sea may be thousands of km away, but its cables are India’s digital lifeline. If they are cut, India bleeds.

The war in West Asia has already claimed lives and destabilised oil markets. If it expands into the realm of digital infrastructure, India could find itself at the frontline of an economic war it did not choose. The lesson is clear: India must treat submarine cables not as invisible threads beneath the sea, but as strategic assets as vital as oil pipelines or trade routes. Protecting them is no longer a technical issue—it is a matter of national security.
