Asia’s stock markets took a drubbing today as a broad tech sell-off rippled across the region, with Japan’s Nikkei shedding 2.3% and South Korea’s Kospi falling 1.8%. The trigger? A cocktail of profit warnings from major semiconductor players and renewed concerns about global demand. But across the English Channel, London’s FTSE 100 has remained remarkably resilient, propped up by a surge in UK-listed semiconductor firms after the government announced a £1.2 billion investment package for domestic chip manufacturing.
The disparity is telling. In Tokyo, investors are fleeing tech stocks like a ship from a leak, dragging down giants such as Tokyo Electron and SoftBank. The rout follows a similar downturn on Wall Street overnight, where the Nasdaq Composite slipped 1.5% as chipmakers like AMD and Intel issued cautious forecasts. The fear is that the post-pandemic boom in electronics is cooling faster than expected, with inventories piling up and order books thinning.
Yet London is playing a different game. The FTSE 100 edged up 0.3% by mid-morning, buoyed by a rally in UK semiconductor stocks such as IQE and Siltronic. The catalyst was a government initiative to boost domestic chip production, a move that has sceptics raising eyebrows. Investors seem to be betting that Britain can carve out a niche in the global chip supply chain, despite the country’s relatively small share of manufacturing.
But let’s be clear: this is a government intervention in a market that is already struggling with overcapacity. The global semiconductor industry is cyclical, and we are clearly in a downcycle. Pumping taxpayer money into a sector that is facing a demand glut smells more like political posturing than sound economics. Will these investments pay off? Only if the UK can lure world-class talent and technology, which is far from guaranteed.
Meanwhile, bond markets are sending their own signals. The yield on the 10-year gilt ticked up to 4.2%, reflecting expectations that the Bank of England may be forced to keep rates higher for longer. That is a headwind for growth stocks, which are particularly sensitive to interest rates. The irony is that while the government is splashing cash on semiconductors, it is also borrowing at increasingly expensive rates. Fiscal responsibility seems to have taken a back seat.
For the UK economy, the resilience of the FTSE 100 masks a more troubling picture. The index is heavily weighted towards old-economy sectors like energy and mining, which have benefited from high commodity prices. But manufacturing output remains weak, and the services sector is showing signs of strain. The divergence between Asia and London today is a reminder that markets are not monoliths. They reflect different exposures to the global economy.
The real question is whether the FTSE’s defensive posture can hold. If the tech rout deepens, it will inevitably spill over into other sectors. After all, the City of London is not an island. Capital flight from Asia could find its way to London, but it could just as easily head to the safety of US Treasuries. The pound, currently trading at $1.26, has been relatively stable, but a risk-off mood could see it slide.
Markets are driven by narratives, and today’s narrative is one of caution. The tech slump in Asia is a warning that the global economy is still grappling with uncertainty. The UK’s semiconductor gamble is a high-stakes bet that may or may not pay off. In the meantime, investors should brace for more volatility. As I always say, there is no such thing as a free lunch especially when the government is picking up the tab.
