Asian financial markets stumbled sharply on Tuesday morning following a wave of profit-taking across semiconductor and technology heavyweights. Sentiment was further unsettled by reports of a breakthrough in Chinese extreme ultraviolet (EUV) lithography manufacturing, raising fears of structural shifts in global tech supply chains and triggering aggressive dumping of regional chipmakers. Coupled with continued volatility in global energy benchmarks as Middle East diplomatic talks remain fluid, investors in Asia are maintaining a defensive posture ahead of key central bank policy decisions later this week.

Global Macro Lead
Overnight action on Wall Street delivered a split finish as investors rotated out of AI-linked tech leaders and into defensive value names ahead of the Federal Reserve’s rate-setting meeting. While the Dow Jones Industrial Average gained 262.83 points (+0.51%) driven by strength in consumer staples and communication services, the tech-heavy Nasdaq dropped -0.18%. Megacap chipmakers bore the brunt of the pressure amid mounting investor scrutiny over hyperscaler capital expenditure returns and circular financing models in artificial intelligence.
In commodities, global oil prices extended their downward trajectory as reports confirmed diplomatic negotiations between the U.S. and Iran regarding Middle East shipping corridors had resumed. Brent crude slipped further below $89 a barrel, while WTI fell toward $82.90. This ongoing retreat in crude prices has helped suppress inflation expectations and eased 10-year US Treasury yields from their recent peaks, offering macro relief to energy-importing Asian economies even as tech sector valuations undergo recalibration.
Regional Asia-Pacific Markets
- Nikkei 225 (Japan): -3.61% (62,584.24) Tumbled to multi-week lows as semiconductor heavyweights like Tokyo Electron and Advantest led a severe tech selloff.
- KOSPI (South Korea): -7.60% (6,221.81) Dived sharply in early trade as memory giants Samsung Electronics and SK Hynix faced heavy selling following the Chinese EUV chip breakthrough report.
- Hang Seng Index (Hong Kong): -0.45% (17,670.15) Slipped moderately as strength in traditional financial stocks was offset by broader regional caution in tech listings.
- Shanghai Composite (China): +0.12% (2,992.30) Edges slightly higher in morning trade as domestic industrial and tech-sovereignty plays gained speculative interest.
- S&P/ASX 200 (Australia): -0.55% (7,772.10) Pulled back due to broad-based declines in mining and energy heavyweights tracking softer global commodity prices.
