Asian Tech Stocks Tumble on AI Funding and Competition Concerns

Asian markets fell sharply on Tuesday, with technology shares leading the decline amid growing investor unease over the massive funding requirements for the artificial intelligence boom and signs of intensifying competition in the semiconductor sector.

Chipmakers Lead a Sector-Wide Rout

Investor sentiment soured following a 2.2% drop in the Philadelphia Semiconductor index overnight. The sell-off was fueled by a Wall Street Journal report that Nvidia (NVDA) is in talks to provide approximately $250 billion in financing guarantees for a major OpenAI data center project, highlighting the immense capital costs associated with AI infrastructure. Nvidia's shares fell 5% on the news.

Compounding the anxiety, a report from The Information stated that China has started manufacturing its own immersion deep ultraviolet (DUV) lithography machines, a critical chipmaking tool long dominated by Dutch firm ASML. This development, signaling a rising competitive threat, sent ASML shares down 8.5%.

Broader Markets Feel the Impact

The tech-focused sell-off triggered a wider market retreat across the region. South Korea’s KOSPI index dived more than 8%, hitting a three-month low and triggering a circuit breaker. In Japan, the Nikkei slid 4%.

"There is clearly a growing sense of optimism within mainland markets about China’s ability to build a globally competitive AI ecosystem," said Chris Weston, head of research at Pepperstone, commenting on the competitive dynamics reshaping the sector.

Oil Prices and Fed Policy in Focus

In commodities, Brent crude futures extended their recent plunge, falling to $87.55 a barrel after a lull in hostilities between the U.S. and Iran. While the drop in oil prices pushed benchmark 10-year U.S. Treasury yields down slightly to 4.64%, it did little to alter expectations for central bank policy.

Traders are pricing in a 38% probability that the U.S. Federal Reserve will raise interest rates by 25 basis points this week. "The U.S.-Iran War, by propelling the price of crude oil, remains the most important determinant of what will happen to the global economy... and, by extension, what informs central bank policy outlooks," noted Thierry Wizman, a strategist at Macquarie Group.
