Global Stock Markets Plunge Amid Tech Selloff and Rising Financial Risks

Market Overview and Key Developments

By Jamie McGeever

ORLANDO, Florida, June 23 (Reuters) - Global stocks slumped in a tech-fueled selloff on Tuesday, with investors unnerved by growing debt-funded AI spending, the prospect of a more hawkish U.S. rate outlook, and tightening financial conditions from a stronger dollar and higher U.S. bond yields.

In my column today I look at how investors may struggle with Fed communications under new chair Kevin Warsh if he adopts the more opaque messaging of the Alan Greenspan era. The chasm between Citi and Bank of America's Fed calls suggests the lack of clear signaling is already playing out.

If you have more time to read, here are a few articles I recommend to help you make sense of what happened in markets today.

Today's Talking Points

Tech Shakeout Intensifies

* Tech shake, rattle and roll

The global tech shakeout intensified on Tuesday. South Korea's KOSPI sank 10%, the U.S. "SOX" chip index fell 8%, and the S&P 500 tech subindex lost 4%. The Nasdaq's 2% decline meant the index lost almost $1 trillion in value.

Some of this is overdue and perhaps even warranted - the SOX hit a record high on Monday, having more than doubled in less than two months. But it's a worry, and fears of bursting bubbles and market turmoil will intensify if there are too many repeats.

Oil Price Reversal

* Oil loses oomph

Oil is down 40% from its Iran war peak, with Brent crude futures on Tuesday posting their lowest close since the conflict began in late February. Brent is below $80/bbl and falling, WTI futures could soon test $70/bbl.

It's a remarkable reversal from well over $100/bbl, and a welcome one for policymakers. Inflationary pressures are fading, and oil is close to being the disinflationary force it was for the whole year before war broke out. On Monday, the year-on-year change in WTI oil had evaporated to zero.

Brexit Anniversary and UK Uncertainty

* 10 years after

Tuesday marked the 10th anniversary of the "Brexit" referendum in 2016 when Britons voted to leave the European Union. The country has been grappling with the economic and political consequences ever since.

Fittingly, the anniversary coincides with yet another handover of power after Prime Minister Keir Starmer on Monday said he will resign. Divisions remain deep, and political and economic uncertainty runs high. There's no sign of that changing any time soon, suggesting a higher risk premium in UK assets.
