The market has spoken, and it has a distinct American accent. Apple’s latest share price surge, driven by investor frenzy over its generative AI pivot, is not just another tech milestone. It is a flashing red light for the British economy. For those of us who have spent two decades watching the City’s pulse, this is a stark reminder of what happens when a country cedes strategic technological ground. The semiconductor supply chain, the lifeblood of AI, is tightening faster than a gilt yield spread in a crisis. And the UK, once a titan of chip design with ARM, is now watching from the sidelines as the chips fall where they may—almost exclusively in Taiwan, South Korea, and the United States.
The Apple story is simple: its stock jumped on reports that it will embed more powerful AI chips into its devices, promising a new era of on-device machine learning. The market cheered, and rightly so from a shareholder perspective. But look closer. Those chips are not built in Cupertino. They are fabricated in foundries thousands of miles away, using equipment and materials controlled by a handful of global players. The UK’s semiconductor industry, once the pride of Cambridge, has been hollowed out by years of underinvestment and a misguided belief that design alone is enough. We sold ARM to SoftBank in 2016, and while it remains a crown jewel, the manufacturing capability that would buffer us from supply shocks has evaporated.
Consider the fiscal backdrop. The government’s own budget watchdog, the Office for Budget Responsibility, has repeatedly warned about the UK’s productivity stagnation. A robust domestic semiconductor industry is precisely the kind of high-value, high-skill sector that could reverse that trend. Instead, we are doubling down on consumption-led growth, subsidising energy bills and printing money through quantitative easing residuals. The result? Persistent inflation that erodes the pound’s purchasing power and makes capital flight more attractive. Gilt yields have been on a rollercoaster, and foreign investors are looking for safer bets. They are not finding them in a UK that cannot even secure its own chip supply.
The government’s National Semiconductor Strategy, unveiled in 2023, was a step in the right direction, but it was more of a stumble. With a paltry £1 billion over ten years, it is a rounding error compared to the $52 billion in the US CHIPS Act or the €43 billion in the European Chips Act. The strategy focuses on design and R&D, which is fine, but it ignores the elephant in the room: we don’t have a single domestic advanced chip fabrication plant. We are entirely dependent on Taiwan Semiconductor Manufacturing Company (TSMC) and Samsung for the most advanced nodes. The geopolitical risks are obvious. Taiwan is a flashpoint, and any disruption would cripple not just Apple, but every tech company that relies on AI.
The market is not stupid. It sees the AI chip crisis coming. Apple’s price surge is a bet on its ability to source chips, not a vote of confidence in the supply chain. The same logic applies to the UK economy. If we cannot guarantee access to advanced chips, our ambitions in AI, quantum computing, and autonomous systems are dead in the water. The Treasury seems oblivious, more concerned with short-term deficit reduction than long-term strategic investment. Fiscal responsibility is important, but not if it comes at the expense of national resilience.
We need to accelerate the semiconductor strategy, and that means putting real money on the table. Private capital will not flow into a sector without government backstops. The British Business Bank should be mandated to co-invest in chip fabrication facilities. We should leverage our strengths in compound semiconductors, where we still have a lead, and build a dedicated foundry for AI chips. It will be expensive, but the cost of inaction is far higher. A 10% disruption in global chip supply could shave 1% off GDP, according to some estimates. That’s £20 billion gone.
The clock is ticking. Every day we delay, the moat around Apple and its American peers widens. The UK cannot afford to be a passive observer in the AI revolution. We need to move from a nation of chip designers to a nation of chip makers. Otherwise, the next Apple price surge will be a reminder not of British innovation, but of British decline.
