Answer

Introduction

Submarine communication cables carry over 95% of global internet traffic and underpin international finance, cloud computing, and communication networks. India’s digital ecosystem is heavily dependent on these cables connecting it to the Middle East, Europe, Southeast Asia, and Africa. Despite their importance, ownership is concentrated among a handful of foreign telecom and tech firms, exposing India and other nations to vulnerabilities from geopolitical disruptions, sabotage, or regulatory constraints.

Strategic and Economic Significance

Global digital economy backbone : Submarine cables enable real-time data transfer, financial transactions, and cloud services.
Eg: The Europe-India SEA-ME-WE 5 cable supports billions in trade and IT exports.
National security and defence reliance : Cables are critical for military communication and intelligence sharing.
Eg: India’s naval and cyber command traffic relies on FA-1 and FLAG cables.
Economic development : Connectivity supports IT, fintech, and e-governance services.
Eg: Bengaluru and Hyderabad data centers depend on multiple redundant cables for uptime.

Vulnerabilities in Ownership and Geopolitics

Foreign ownership concentration : Over 70% of cables terminating in India are operated by multinational corporations.
Eg: Reliance on Google, Meta, and Telxius cables increases dependence on foreign policies.
Geopolitical risks : Conflicts, sanctions, or territorial disputes may threaten cable maintenance or access.
Eg: Tensions in the South China Sea or Gulf of Oman could disrupt key routes.
Physical and cyber threats : Submarine cables are susceptible to sabotage, natural disasters, and cyber intrusion.
Eg: September 6, 2025 Red Sea Cable Crisis, where the severing of SMW4 and IMEWE near Jeddah triggered severe latency across Indian banking nodes and cloud networks.

Way Forward

Diversify cable ownership : Encourage domestic telecom and private firms to invest in international cable projects.
Eg: Tata Communications co-owns some international routes, reducing reliance on foreign entities.
Redundant and alternative routes : Establish multiple geographically diverse cable paths to ensure continuity.
Eg: India-Middle East-Europe (IMEWE) and Bay of Bengal Gateway (BBG) serve as complementary pathways.
Strengthen cyber-physical security : Deploy monitoring, rapid response, and encryption protocols for data integrity.
Policy and multilateral coordination : Frame legislation to protect critical digital infrastructure and participate in international cable governance forums.
Eg : Enforcing the DoT’s newly accepted TRAI Submarine Cable Landing Station (CLS) Regulatory Mechanism, which strictly mandates that Indian licensed entities maintain operational control and security oversight over all international fiber endpoints terminating in domestic waters.

Conclusion

Submarine cables are lifelines of the modern digital economy, yet concentrated foreign ownership and geopolitical tensions make them vulnerable. India must pursue strategic diversification, robust security, and policy interventions to safeguard these critical infrastructures and ensure continuity of economic and national security operations.
