IRGC-affiliated news agency Tasnim published what it called "three practical steps for generating revenue from Strait of Hormuz internet cables." A companion piece in Fars, a second IRGC-linked outlet, went further, floating the idea of severing the cables entirely, with disruption costs estimated in the tens to hundreds of millions of dollars per day. Tasnim and Fars function as operational mouthpieces for the Islamic Revolutionary Guard Corps. Their proposals track closely with how Iran has historically signaled military intent, floating ideas publicly before acting on them. The cables they are describing carry close to $10 trillion in financial transactions daily. Several are owned or co-invested in by Meta Platforms, Google, Amazon, and Microsoft. The companies that would have to repair them, assuming they could even access the war zone, operate a global fleet numbering fewer than 60 vessels. The closest ones are currently parked. --- ## What the Cables Are and What They Carry Undersea fiber-optic cables are the physical backbone of the internet. Satellites handle less than 1% of intercontinental data, according to the International Telecommunication Union. The other 99% moves through approximately 600 cable systems laid on the ocean floor, totaling more than 1.4 million kilometers of cable worldwide. At the Strait of Hormuz, multiple major cable systems converge at one of the most geographically constrained points on earth. Iran has never granted permits for cables to cross its territorial waters, which means every cable connecting South and Southeast Asia to Europe via the Persian Gulf must route through the narrow southern passage of the strait. The result is a compressed cluster with very limited geographic separation. The cables that cross the strait: - **AAE-1 (Asia-Africa-Europe 1)**: A 25,000-kilometer system connecting Hong Kong, Vietnam, Cambodia, Malaysia, Singapore, Thailand, India, Pakistan, Oman, the UAE, Qatar, Yemen, Djibouti, Saudi Arabia, Egypt, Greece, Italy, and France. Owned by a consortium including Ooredoo, STC, du, and Telecom Egypt. - **SEA-ME-WE 5 (Southeast Asia-Middle East-Western Europe 5)**: Built on 100 Gbps technology with an initial capacity of 24 terabits per second. Lands in Singapore, Myanmar, Bangladesh, India, Sri Lanka, Pakistan, UAE, Oman, Djibouti, Yemen, Saudi Arabia, Egypt, Turkey, Italy, France, and the UK. Consortium members include Telecom Italia, Orange, SingTel, Tata Communications, and Vodafone. - **Falcon**: Operated by Flag Telecom. Connects the UK, France, Spain, Egypt, Djibouti, the UAE, Oman, Kuwait, and Bahrain. - **Gulf Bridge International (GBI)**: Links GCC countries to Europe via Jordan and Egypt. A terrestrial-and-submarine hybrid used as a primary carrier path by Gulf telecom operators. - **2Africa and 2Africa Pearls**: Meta's flagship undersea infrastructure investment. The 45,000-kilometer core cable encircles the African continent, designed to serve more than 3 billion people across 35 countries. The 2Africa Pearls extension was designed to branch into the Persian Gulf, with landing points in Saudi Arabia, the UAE, Kuwait, Bahrain, Qatar, Oman, and Pakistan. Meta paused all 2Africa Pearls work in the Persian Gulf in March 2026 after the Iran conflict made deployment untenable. The cable ship remains repositioned outside the region. TeleGeography has called the Hormuz corridor one of the most concentrated submarine cable chokepoints in the world outside the Suez Canal. --- ## The $10 Trillion Pressure Point The $10 trillion daily transaction figure cited by Tasnim covers the aggregate financial data transiting the Gulf corridor cable network: - SWIFT interbank payment instructions - Real-time gross settlement traffic - Foreign exchange transactions - Derivatives clearing communications - High-frequency trading data flows Cutting a cable does not freeze a bank's assets. It severs the communication channel through which transaction instructions are transmitted and confirmed, introducing latency, errors, and at scale, failures. The UAE alone processed more than $400 billion in financial transactions in 2024, the overwhelming majority transiting the cable systems running beneath the strait. Dubai's position as a regional financial center, hosting 300-plus banks and financial institutions from more than 100 countries, depends on sub-20-millisecond latency connections to London, Singapore, Hong Kong, and Mumbai. Saudi Arabia's Vision 2030 agenda is equally exposed. Riyadh's partnerships with Google, Amazon Web Services, and Microsoft Azure all require high-capacity, low-latency undersea connectivity to function at commercial scale. A cable disruption would impair the digital service economy that Vision 2030 is explicitly designed to build. --- ## The Clustering Problem The Hormuz cables are vulnerable for geographic reasons that decades of Iranian policy created. Iran's refusal to grant cable crossing permits has forced every operator planning a Gulf-to-Europe route to use the same narrow southern corridor of the strait. The cables are packed into a compressed band on the Arab side of the waterway, separated from each other by distances that a single well-placed anchor drag, let alone a deliberate military action, could breach simultaneously. The Red Sea precedent is instructive. In 2024, Houthi rebels attacked a vessel transiting the Red Sea. The ship lost maneuverability, dropped its anchor uncontrolled, and dragged it for two weeks before sinking. The anchor severed three major undersea cables: AAE-1, Seacom, and EIG. Repairs took months. That damage was accidental. Iran's IRGC operates a naval force specifically designed for asymmetric warfare in confined waters and has practiced underwater demolition operations. It would not need to be careless. TeleGeography's Alan Mauldin, writing in March 2026, noted that the clustering in the Hormuz corridor means a small number of targeted actions could sever the bulk of capacity on the Asia-Europe-Gulf route simultaneously, with no practical redundancy available within the strait itself. --- ## Who Would Fix Them Approximately 60 cable repair vessels operate worldwide, owned or operated by a small number of specialized firms: - **Alcatel Submarine Networks** (a Nokia subsidiary) - **SubCom** (US-based; operates the 140-meter Reliance vessel with DP2 capability and cable burial sea plow) - **NTT World Engineering Marine** (Japan-based; operates the cable-laying vessel Kizuna) - **E-marine** (UAE-based, founded in the 1990s; primary servicer of Gulf cable systems) E-marine is the most operationally relevant for the Hormuz scenario. Operating out of Abu Dhabi with vessels including the CS Maram, the company has maintained the Gulf cable network for decades. Under normal conditions, E-marine could mobilize and reach a fault in the Gulf within 24 to 48 hours. These are not normal conditions. Repair vessels require passage through or near the strait to access a fault inside it. During active military conflict: - Access to the operational zone requires naval coordination, risk insurance, and flag-state permission - No commercial insurance underwriter will extend war-risk coverage for a cable ship entering a contested military zone without government-backed guarantees - The frameworks that enabled Red Sea repair operations during the Houthi campaign have no equivalent for the Strait of Hormuz Standard repairs on accessible cables take two to four weeks from vessel mobilization to restoration. In politically contested or militarily active waters, that timeline doubles or quadruples, assuming access is granted at all. In the case of cables severed near Iranian territorial waters, Iran would have effective veto power over whether a repair vessel could approach the fault site. --- ## What Happens to the Internet A total severance of the Hormuz cable cluster would not produce a uniform global blackout. But the rerouting options are severely constrained by geography. Traffic would need to shift to one of two alternatives: - **The Suez Canal route**, which faces its own disruption risk given the ongoing Red Sea conflict - **Satellite links**, which lack the capacity and latency characteristics required for financial services, real-time cloud computing, and high-volume video transmission The impact by region: - **Gulf states (UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, Oman)**: Direct and severe. Minimal alternative terrestrial routing for international traffic exists. These are economies connected to the global internet almost entirely by sea. - **India, Pakistan, and Southeast Asia**: Significant but partially absorbable. India has invested in alternative cable routes that partially bypass the Gulf corridor. Financial services operators in Mumbai, relying on sub-10-millisecond connections to Gulf exchanges and European clearinghouses, would face harder choices. - **US hyperscalers**: Meta, Google, Amazon, and Microsoft would see degraded cloud performance across the Middle East, impaired returns on data center investments in the UAE and Saudi Arabia, and damaged business cases for the hundreds of billions in Gulf technology commitments announced over the past three years. --- ## The Licensing Gambit Iran's three-step plan, as outlined by Tasnim, escalates from extraction to control: 1. **Initial licensing fees** on all foreign-owned cables transiting the strait, with annual renewals 2. **Jurisdictional control**: requiring Meta, Amazon, and Microsoft to operate under Iranian law as a condition of cable access 3. **Operational transfer**: moving exclusive control and maintenance of the cabling to Iranian companies No international legal framework supports the claim. The United Nations Convention on the Law of the Sea establishes the right of transit passage through international straits and explicitly prohibits coastal states from interfering with cable traffic. Iran has never ratified UNCLOS and does not recognize these obligations as binding. What Iran does have is the physical ability to enforce its position regardless of legal standing. The IRGC's naval forces have seized, boarded, and detained vessels transiting the strait multiple times over the past decade. Applying the same logic to a cable repair vessel, or to a cable itself, would be a new escalation in kind, though not in category. --- ## The Stakes for Gulf Digital Ambition The UAE's G42, Microsoft, Google, and Amazon have committed a combined estimated $100 billion to Gulf-region data center and cloud infrastructure over the next five years. Saudi Arabia's Humain, the state-backed AI company launched in 2025, has signed partnerships with Nvidia, AMD, and AWS premised on high-capacity connectivity to global cloud networks. None of these investments function as marketed if the cables connecting them to the rest of the world are severed, taxed, or held hostage. The Iran conflict has already extracted concrete costs: - Iranian drone strikes hit data centers in Bahrain and the UAE earlier in 2026, causing physical destruction to server infrastructure - Meta's 2Africa Pearls deployment is stalled - At least five other scheduled Gulf cable projects are delayed indefinitely, according to AGBI reporting, with engineering teams and ships repositioned away from the operational zone The Tasnim and Fars articles may be the latest iteration of saber-rattling calibrated to produce concessions in negotiations. They may also be the operational preview for something already planned. A severed fiber-optic cable in a contested military zone can sit on the ocean floor, inert, for months. An oil tanker that survives a maritime incident resumes service. That asymmetry is the actual threat.
