Asian stocks extended losses into a second day in early ‍trading on Friday as a selloff on Wall Street intensified, with precious ​metals and cryptocurrencies gripped by wrenching volatility.

MSCI’s broadest index of ⁠Asia-Pacific shares outside Japan fell 0.9 per cent, led by a 5.0 per cent dive in South Korea’s Kospi which triggered a brief trading halt shortly after the open. Japan’s Nikkei 225 shed 0.7 per cent, while S&P ‌500 e-mini futures ​slid 0.6 per cent as Nasdaq e-mini futures tumbled 1.1 per cent.

“Investors are ‍questioning their commitment to the pillars that have underpinned markets over the past six months: AI, crypto, and precious metals,” said Tony Sycamore, market analyst at IG in Sydney. “This raises the odds of ​a deeper unwind.”

Stocks sold off ‌overnight on fears that new AI models may start to eat into the ​profits of software firms, with the S&P 500 turning negative ‍for the year as fears around the labour market grew.

Layoffs announced by US employers surged in January to ​the highest ​level for the ​month in 17 years, a survey ​from global outplacement firm Challenger, Gray & Christmas showed on Thursday.

Precious metals saw little respite, with gold falling 1.6 per cent to $US4,691.76 ($A6,720.51), and silver plunging another 8.9 per cent to $US64.912 ($A92.980).

Cryptocurrency markets extended also losses after breaching several milestones in a $US2 trillion ($A2.9 trillion) wipeout on Thursday, with bitcoin tumbling 3.0 per cent to $US61,238.64 ($A87,718.71) ‍and ether down 1.8 per cent at $US1,813.77 ($A2,598.06).
