Asian markets rebound after CoreWeave stock shock

Asian stocks have rebounded following heavy selling in the previous session when investors dumped tech shares as questions about cloud company CoreWeave's debt pile fuelled worries about the financing driving the AI boom.

Bond markets stabilised after yields plunged on Thursday as traders bought up Treasuries and other safe-haven sovereign debt. The dollar limped towards its first weekly loss in five weeks as lower US yields eroded the currency's appeal.

Gold eased back from Thursday's high, while Brent crude drifted lower toward $US105.

In Asia, Japan's tech-heavy Nikkei rose 1.8 per cent, making back some of Thursday's almost five per cent tumble. South Korea's KOSPI climbed 2.8 per cent, following a nearly eight per cent plunge.

Taiwan's stock benchmark rose 0.7 per cent and Hong Kong's Hang Seng added 1.1 per cent. Mainland Chinese blue chips edged 0.3 per cent higher.

Indonesia's equity benchmark slumped 11 per cent after MSCI said the country's stock market is no longer worthy of "emerging market" status, and is preparing to cut it from a suite of products tracked by global investors, a major setback likely to send money fleeing. The rupiah weakened about 0.8 per cent to 95.0550 per US dollar.

US stock futures were lower, with tech-focused Nasdaq futures off 0.3 per cent and S&P 500 futures down 0.1 per cent, after the respective cash indexes notched small gains on Thursday.

Shares of Nvidia-backed CoreWeave recovered some composure on Thursday after starting the session by extending Wednesday's 15.5 per cent slump amid reports that its bond yields had reached highs associated with distressed debt, triggering a broad, AI-centred equity selloff globally.

Analysts also pointed to the pressure on memory maker shares this week after China's ChangXin Memory Technologies (CXMT) reported progress on a next-generation DRAM architecture that could intensify competition with established manufacturers.

"Global markets are getting very noisy once again after a period of low volatility: Wall Street is whipsawing, bond yields are swinging, currency markets are doing backflips, and commodity prices are running in multiple directions," Kyle Rodda, a markets analyst at Capital.com, wrote in a client note.

"Global markets could potentially be in for a protracted period of this sort of volatility," with tech company earnings announcements due in the coming weeks, and markets also attempting to discern the trajectory of US and other major economies' interest rates, he said.

Federal Reserve Chair Kevin Warsh, along with a host of other global central bank officials, will speak at events at the IMF-World Bank Annual Meetings in Bangkok during the day.

However, "given his notorious reticence and outright disdain for anything that resembles 'forward guidance', market participants will be forced to work hard to infer any insight from Warsh," Rodda said.

Most Japanese government bond yields rose, retracing about half of Thursday's decline, as they took cues from a smaller bounce in Treasury yields on Thursday following the prior session's plunge.
