The Bank of England’s battle against inflation has encountered an unexpected foe: the artificial intelligence boom. New data reveals that surging costs for advanced semiconductors, driven by demand from tech giants like Apple and Nvidia, are feeding through to higher consumer prices in Britain. This is not a transitory supply shock but a structural shift in the cost base of the modern economy.
Consider the numbers. The producer price index for computer components jumped 8.2% year-on-year in the latest quarter, the fastest pace since the pandemic. That increase is now being passed along the supply chain. Apple, for instance, has raised prices on its latest iPhone models by an average of £150 in the UK, citing higher chip costs. Nvidia’s flagship AI accelerators now cost 12% more than their predecessors. These are not isolated incidents: they reflect a market where demand for cutting-edge chips far outstrips supply.
What does this mean for British inflation? The direct impact is modest: semiconductors account for only 1.5% of the consumer price index basket. But the indirect effects are more worrying. Higher chip prices raise costs for every industry that relies on digital processing, from automobiles to cloud computing. The services sector, which dominates the UK economy, is particularly vulnerable as firms upgrade AI infrastructure. The Bank of England’s preferred measure of underlying inflation, services CPI, remains stubbornly above 5%, partly because of these technology costs.
Critically, this inflation is global in origin, not domestic. The Bank cannot lower it by raising interest rates alone. A tighter monetary policy might cool UK demand, but it will not add a single wafer to GlobalFoundries or TSMC’s fabrication lines. The risk is a policy error: the Monetary Policy Committee, fixated on wage growth and services prices, may over-tighten, crushing the economy without taming the chip-driven price pressures.
Meanwhile, the gilt market is sniffing trouble. The 10-year yield has risen 35 basis points this month to 4.2%, partly on inflation concerns. The yield curve is steepening, a sign that investors expect the Bank to lag the curve. Capital flight is a distant threat for now, but the pound’s recent weakness against the dollar reflects fears that the UK is importing inflation from the US tech sector.
The Chancellor’s fiscal position is caught in the crossfire. Higher inflation pushes up debt interest payments, which track the RPI. The Office for Budget Responsibility will need to revise its forecasts. With little room for manoeuvre, the government faces a choice: either accept higher borrowing costs or slash public spending. Neither is palatable ahead of a general election.
What is the solution? The UK cannot control global chip prices. But it can insulate itself by boosting domestic semiconductor production. The £1 billion National Semiconductor Strategy is a start, but it is dwarfed by the $52 billion in US CHIPS Act subsidies. Britain needs a more ambitious programme to attract fabrication plants, or it will remain a price-taker in the AI economy.
Until then, the Bank of England is fighting two battles: one at home against domestic inflation, and one abroad against the relentless rise of AI chip costs. It is losing both. Investors would do well to hedge their bets: short long-dated gilts, long inflation swaps, and for heaven’s sake, buy Apple shares. The company’s pricing power is a feature, not a bug.
