Asian stock markets suffered a sharp sell-off on Monday, extending a global tech rout that has wiped billions off valuations in a matter of days. The Nikkei 225 plunged more than 4%, while Hong Kong's Hang Seng index fell 3.5% and South Korea's KOSPI shed 3.2%. The catalyst? A perfect storm of rising bond yields, hawkish central bank rhetoric, and renewed fears that the era of cheap money is ending.
The trigger for the latest wave of selling came from Wall Street, where the tech-heavy Nasdaq Composite tumbled 3.2% on Friday, its worst day since March 2020. The culprit was a surge in US Treasury yields, with the 10-year note hitting 4.5% for the first time in four months. This is a classic case of 'good news is bad news.' Strong economic data, particularly a surprisingly robust jobs report, has fuelled speculation that the Federal Reserve will keep rates higher for longer. For equity markets, especially richly valued tech stocks, higher discount rates are poison.
The pain was felt across Asia. Japan's chip-related stocks, such as Tokyo Electron and Advantest, were among the biggest losers, falling 6% and 7% respectively. In South Korea, Samsung Electronics slid 4% and SK Hynix dropped 5%. China's benchmark CSI 300 index, though less exposed to global tech, still fell 2%, dragged down by losses in semiconductor and internet firms. The sell-off was indiscriminate: investors are rotating out of growth stocks and into defensive sectors, a classic sign of risk aversion.
The bond market is sending a clear signal. The yield on the 30-year UK gilt rose to 5.1%, its highest since 1998, reflecting similar dynamics. Central banks are trapped: they want to tame inflation but cannot risk crashing their economies. The Bank of Japan, which has long resisted tightening, is now under pressure as the yen weakens further, stoking import costs. The irony is that the very policies designed to support markets during the pandemic are now their undoing.
Capital flight is accelerating. Investors are fleeing emerging markets and piling into the US dollar, which hit a two-month high against a basket of currencies. The dollar-yen pair breached 152 for the first time since 1990, forcing Japanese authorities to issue fresh warnings about intervention. Currency volatility is the last thing Asian companies need, especially those with dollar-denominated debt.
The question is: how much lower can markets go? Valuations in the tech sector remain stretched relative to history, despite the correction. The Nasdaq is still trading at 30 times forward earnings, well above its 10-year average of 25. Meanwhile, earnings estimates are being revised down as companies warn of margin compression. The Bloomberg World Tech Index has already fallen 15% from its peak, but I suspect there is more pain ahead.
For investors, the lesson is clear: central bank liquidity is no longer the tide that lifts all boats. The party is over. The only safe havens right now are cash and short-dated government bonds. Equities, particularly in the tech space, are a dangerous bet. As I have always said, when the music stops, you do not want to be left holding the most overvalued chairs.
The Asian session tonight will be crucial. If the sell-off continues, we could see coordinated intervention from Asian central banks to stem the rout. But do not expect a miracle. The bottom line is that markets are repricing for a world of higher rates, and that process is not yet complete. Buckle up.
