Executive Summary: Iran's Hormuz Cable Fee ProposalIran has floated a plan to charge US tech companies for using the undersea internet cables that pass through the Strait of Hormuz. The proposal, aired by state‑linked outlets Tasnim and Fars, claims the scheme could generate hundreds of millions of dollars each year, but experts question its legality and technical feasibility.Details of the Proposed Licence RegimeThe media brief outlines three core elements:Impose licence fees on foreign firms that transmit data over the subsea cables.Require the so‑called “technology giants” – specifically Meta, Google, Amazon and Microsoft – to operate under Iranian law, effectively forcing joint‑venture arrangements.Monopolise repair and maintenance services for the cables, charging the world for any restoration work.Iran justifies the move by citing article 34 of the 1982 UN Convention on the Law of the Sea, which it interprets as granting rights over the seabed of the strait.Financial Estimates and Comparative BenchmarksWhile the exact figure is vague, Tasnim suggests the scheme could bring in hundreds of millions annually. For context, the proposal references Egypt’s model, where fees on cables crossing Egyptian territory are estimated to generate between $250 million and $400 million per year, though precise revenues are not publicly disclosed.Strategic and Operational Implications for the Gulf RegionSeven major cables run beneath the Hormuz strait, many supporting the rapid AI and cloud expansion in Gulf states. Potential consequences include:Disruption of regional internet traffic if fees are enforced or if repair ships are deterred.Limited global impact, as most traffic on these cables serves Gulf countries rather than trans‑Eurasian routes.Increased geopolitical tension, especially given US naval patrols and the strategic importance of the waterway.Experts note that most cables do not terminate in Iran, making fee collection technically challenging. Additionally, imposing tolls would likely require threats or physical interference, a step not previously observed.Outlook: Feasibility, Enforcement, and Regional TensionLegal analysts highlight sanctions and international law as major obstacles. Technically, separating traffic by company is infeasible, and cutting or seizing cables would demand capabilities Iran does not demonstrably possess. Even if Iran attempted to threaten repair vessels, such ships typically avoid operating under fire, potentially prolonging any disruption.In the near term, the proposal appears more rhetorical than actionable, serving as a bargaining chip in the broader US‑Iran confrontation. Unless Iran can develop the requisite maritime and cyber‑monitoring infrastructure, the likelihood of a sustained, enforceable fee regime remains low.

The Market Warning Stock markets are too high and are going to drop back at some point due to the many risks facing the global economy, according to Sarah Breeden, deputy governor of the Bank of England. Speaking to the BBC, Breeden issued this prediction at a time when the US stock market has risen to record levels despite ongoing Middle East conflicts. "There's a lot of risk out there and yet asset prices are at all-time highs. We expect there will be an adjustment at some point," Breeden stated, emphasizing that while she's not predicting an imminent correction, the financial system needs to be resilient enough to cope when it occurs. The Financial Policy Committee's Assessment This warning chimes with the latest assessment from the Bank's financial policy committee, which has pointed to specific risks from high AI valuations, potential AI disruption, and vulnerabilities in the private credit market. The big fear is that several risks could crystallize simultaneously—such as an economic shock leading to a rapid readjustment of AI valuations that could hurt confidence in private credit markets. "What we are watching for: is how might those prices fall? Will there be a sharp adjustment downwards? And if there is such an adjustment, how will that affect the economy?" Breeden explained. "I'm not saying it will happen today, tomorrow, in 12 months' time. It's ensuring that if it happens the system is resilient." The Trade Tensions Escalate The threat of a new UK-US trade war has reared up again after Donald Trump threatened to impose tariffs on the UK if it doesn't drop its digital services tax on US social media firms. Speaking from the Oval Office, the US president warned: "We've been looking at it and we can meet that very easily by just putting a big tariff on the UK, so they better be careful. If they don't drop the tax, we'll probably put a big tariff on the UK." The digital services tax, introduced in 2020, imposes a 2% levy on the revenues of several major US tech companies. The Trump administration has been consistently pushing back against this tax. In December, the US paused its promised multi-billion-pound investment into British tech in protest that trade barriers hadn't been lowered. The Market Impact Analysis These dual developments—market correction warnings and escalating trade tensions—create significant uncertainty for investors and businesses. The combination of potential market volatility and trade protectionism could create a challenging environment for global economic growth. Financial markets have shown remarkable resilience in the face of geopolitical tensions, with the US stock market reaching record levels despite conflicts in the Middle East. However, central bankers like Breeden are increasingly concerned that this resilience may be masking underlying vulnerabilities that could lead to a significant correction. The Global Outlook Looking ahead, investors and businesses should prepare for potential market volatility as these situations develop. The Bank of England appears focused on strengthening the UK financial system to withstand potential shocks, while the UK government faces the delicate task of managing its relationship with the US while maintaining its digital services tax. Today's economic calendar includes several key indicators that could influence market sentiment: the UK retail sales report for March at 7am BST, the IFO survey of German business confidence at 9am BST, and Russia's interest rate decision at 10.30am BST. These data points will provide further insight into the global economic landscape as these tensions unfold.

China has emerged as a leader in global AI governance, contrasting with the US, which is pursuing AI development in a 'wild west' manner, according to Prof Dame Wendy Hall, a former UN and UK government adviser. Hall told the House of Commons business and trade committee that China is backing multinational attempts to introduce global governance of AI, while the US has set up a race between profit-hungry companies that rely on hype.Hall, who is director of the Web Science Institute at the University of Southampton, said Chinese AI researchers are efficient, innovative, and willing to release their models on an open-source basis. However, she noted that it has become increasingly difficult for UK experts to collaborate with China on research, limiting her academic freedom.The UK's reliance on US tech companies, including Google, Microsoft, OpenAI, and Amazon, risks a repeat of the Post Office Horizon scandal, warned Neil Lawrence, Cambridge University's DeepMind professor of machine learning. He expressed concerns that the UK is outsourcing AI model development to private billionaires with zero loyalty to the British state and consumer.Hall and Lawrence also highlighted that promises from US-backed tech companies may not be delivered as planned. For example, OpenAI has put a UK datacentre project on hold, and a government plan to open a large UK sovereign AI datacentre is behind schedule.The tech industry has identified a lack of power as a key problem, with Microsoft saying a planned datacentre in the north of England will not come online until at least 2033 due to a shortage of power from the grid.
