Asian stock rout deepens as AI worries grip markets

Market turmoil intensifies amid AI and geopolitical concerns

By Ankur Banerjee

AI-driven rally faces skepticism

SINGAPORE, July 29 (Reuters) - Asian stocks sank on Wednesday, extending a vicious selloff as anxiety about AI valuations and whether the massive spending will deliver returns rattled investors ahead of crucial earnings from big tech firms and a U.S. Federal Reserve policy decision.

Oil prices surge on Middle East tensions

Oil prices jumped after fresh attacks in the Middle East shattered the relative calm of recent days in the U.S.-Iran war as investors fret about the impact of depleting supplies on prices and global rates. 

Asian chipmakers at the center of volatility

Asian chipmakers have been at the epicentre of this year's AI-driven rally and, more recently, investor concerns about its staying power, sparking sharp market swings.

Major indices and company performance

South Korea's KOSPI, which had more than tripled over 12 months to June, sank over 11% to its lowest level since early April, after dropping more than 10% on Tuesday. Taiwan stocks fell 5% while Japan's Nikkei slid 2.6% as the rout deepened across the region.

That left MSCI's broadest index of Asia-Pacific shares outside Japan down over 2.45% after shedding 3.6% on Tuesday.

Shares of SK Hynix fell 9% as investors digested earnings that showed the chipmaker increased quarterly operating profit more than sixfold but missed lofty expectations.     

Investor sentiment and tech earnings

"SK Hynix delivered strong results, but in today’s AI market, strong is no longer enough," said Gary Tan, portfolio manager at Allspring Global Investments.

"Investors were looking for additional catalysts, particularly around long-term agreements and shareholder returns, to support a memory sector that has become the epicentre of the AI trade," Tan added.

Earnings from the "Magnificent Seven" members Microsoft and Meta later in the day will be a key test of the AI trade, particularly after Alphabet and Tesla spooked investors last week with negative cash flow reports.

"This round of earnings would need to prove that the huge capital expenditure has paid off else we may see the market drag further," said Sean Teo, sales trader at Saxo in Singapore.

Teo also said investors are now getting wary of circular financing where a handful of companies are investing into each other in somewhat of a closed loop where organic demand becomes unclear.

Nasdaq futures fell 0.7% in Asian hours while European futures slid 0.6% as the selling appeared to spread to other regions. Hong Kong's Hang Seng index bucked the trend and was up 1.4%.

Oil jumps ahead of Fed meeting

Middle East conflict impacts energy markets

Brent futures jumped over 3% to $87.19 per barrel while U.S. West Texas Intermediate (WTI) crude rose more than 3% to $82.08 after U.S. Central Command said Iran had launched multiple ballistic missiles that were successfully intercepted.

"The latest attack highlights that the two sides remain a long way from resolving the core dispute of passage through the Strait of Hormuz that caused the earlier MOU to collapse," said Tony Sycamore, market analyst at IG.    

Iran effectively shut the key waterway to ships other than its own after the U.S. and Israel launched strikes on February 28. A deal last month between Washington and Tehran partially reopened it, but the agreement collapsed in early July after Iran fired on ships using a channel it had not approved.

Inflation and Fed policy outlook

That has again put inflation pressures in the spotlight ahead of the Federal Reserve's policy decision due later on Wednesday. The U.S. central bank is seen as more likely to leave interest rates steady even as a growing number of its policymakers fret openly about inflation.

The decision remains unusually hard to call under the no-guidance regime adopted by the new Fed Chair Kevin Warsh, with traders pricing in a 33% chance of a hike. The U.S. dollar was perched near a one-month high ahead of the decision. [FRX/]

"We think the market may once again be underestimating the extent of the hawkish shift at the Fed, and that the (for now) moderate increase in energy prices may tip an already finely balanced meeting in favour of a hike this week," said Frank Flight, head of macro strategy at Citadel Securities. 

"We acknowledge that it is a close call, but we now see a rate hike at the July meeting," Flight said.
