The morning bell across Asian exchanges rang with a distinctly pessimistic tone, as a broad sell-off in technology shares erased billions in market value. Tokyo’s Nikkei 225 tumbled 2.1%, with semiconductor giants like Tokyo Electron and Screen Holdings shedding over 3% on fears of a global demand slowdown. Seoul’s Kospi followed suit, dropping 1.8% as Samsung Electronics and SK Hynix led the decline. Hong Kong’s Hang Seng Tech Index plunged 3.2%, weighed down by Alibaba and Tencent, as regulatory jitters resurfaced. Investors are clearly rotating out of growth names, chasing safety amid rising bond yields and hawkish central bank rhetoric.
Yet, in a curious divergence, London’s FTSE 100 opened broadly flat, defying the Asian gloom. The index found an unlikely anchor in British semiconductor stocks. Shares of IQE, the Cardiff-based wafer maker, jumped 4.5% after announcing a new supply deal with a US defence contractor. ARM Holdings, though not listed, casts a long shadow; its royalty revenue is a bellwether for UK chip intellectual property. The FTSE 350 Technology Index rose 0.3%, bucking the global trend. This is the old-economy resilience that investors love to hate: pharmaceuticals, miners, and energy stocks also lent support, cushioning the index from the tech wreck.
But let us not mistake this for strength. The FTSE’s steadiness is a symptom of capital crowding into defensive sectors, not a vote of confidence in the UK economy. The gilt market tells a murkier story. The 10-year yield edged up to 4.12% this morning, reflecting jitters ahead of the Bank of England’s decision this Thursday. Markets are pricing in a 40% chance of a quarter-point hike, despite inflation easing to 3.2%. If the MPC blinks, we could see sterling slide and gilt yields spike. The old adage holds: when America sneezes, Asia catches a cold, but Britain just takes a paracetamol and carries on.
The underlying rot is the same everywhere: rising real yields. The US 10-year Treasury yield breached 4.5% overnight, its highest since November. That is kryptonite for tech stocks, whose valuations rest on promises of distant cash flows. Discount those promises at 4.5%, and they suddenly look flimsy. Asia is feeling the heat first because its tech sector is levered to exports. Japan’s chip equipment makers rely on China demand, which is stalling. South Korea’s memory chip glut persists. Meanwhile, Britain’s semiconductor strength is niche: compound semiconductors for defence and automotive, less cyclical than memory. That explains the FTSE’s relative calm, but it is a thin reed.
What keeps me up at night is capital flight. Emerging Asian markets saw $2.3 billion in outflows last week, the largest in three months. That money is heading back to US dollar assets, seeking yield. Sterling is caught in the crosswinds: up 0.1% against the dollar this morning, but down 0.5% against the euro. The safe-haven bid is real, and it is not going to London. The FTSE 100 may hold today, but if global risk appetite sours further, no sector is immune. Watch the Vix: it is up 8% at 21.5. Volatility is back, and with it, the bottom line.
For now, the UK market is a lifeboat in a storm: stable, but crowded. The semiconductor story is a bright spot, but it cannot carry the whole index. The tech rout in Asia is a warning shot. Governments and central banks must resist the urge to meddle. Fiscal discipline, not stimulus, will restore confidence. The market always has the last word.
