Hong Kong sold off hard while Taiwan rallied — and now a tech-heavy US selloff overnight adds another layer of uncertainty as Asia heads into Tuesday’s open.

Where Asia Closed Yesterday

The headline split was China weakness versus pockets of strength in Japan and Taiwan. The Hang Seng fell 1.59% to 23,924, its sharpest single-session drop in weeks, dragged lower by property and consumer names as confidence around China’s domestic recovery wavered. The Shanghai Composite slipped 0.43% to 4,090, though the Shenzhen Component bucked the trend with a 0.94% gain — suggesting mainland investors rotated into smaller-cap tech and growth names even as blue chips faded.

Japan’s Nikkei 225 eked out a 0.28% gain to 71,250, with exporters finding support from a weaker yen (USD/JPY holding above 162). Taiwan’s TAIEX was the standout, jumping 1.28% to 46,465, lifted by semiconductor strength — TSMC and its supply chain continue to benefit from the global AI buildout theme.

Elsewhere, the picture was softer. Australia’s ASX 200 dropped 0.92% to 8,828, weighed down by materials and energy. India’s Nifty 50 fell 0.64% to 24,013, extending a cautious streak. South Korea’s KOSPI was nearly flat at -0.13%, while Singapore’s Straits Times Index lost 0.39% and New Zealand’s NZX 50 dipped 0.23%.

US Overnight Snapshot

Wall Street closed mixed with a clear rotation signature. The Nasdaq Composite dropped 1.32% as big tech stumbled — Oracle fell on higher capex guidance and an equity raise, Intel’s CEO delivered what investors took as a reality check, and the broader AI-infrastructure trade showed fatigue. The S&P 500 slipped 0.37%.

But the Russell 2000 gained 0.88%, signalling money moving into domestically oriented small caps rather than fleeing risk entirely. The VIX rose 5.37% to 17.3 — not panic territory, but enough to flag that hedging demand is picking up.

For Asia, the Nasdaq weakness is the signal that matters most. HKEX-listed tech (Alibaba, Tencent, Meituan) and KOSPI semiconductor names (Samsung, SK Hynix) typically mirror US tech sentiment at the open. The Russell strength won’t translate — Asia doesn’t have an equivalent domestic small-cap catalyst right now.

Commodity + FX Watch

Oil’s 3.02% overnight plunge to $74.30 is the sharpest commodity move on the board and will weigh on energy names across the region — Woodside and Santos on the ASX, CNOOC and PetroChina in Hong Kong. Copper slipped 0.34%, a mild headwind for ASX miners like BHP and Rio Tinto but not enough to force aggressive selling on its own.

Gold pulled back 0.41% to around $4,210, easing from recent highs. That may cool some enthusiasm for gold miners on the ASX, though the move is modest.

On FX, AUD/USD dipped 0.15% — no drama, but the direction keeps pressure on Aussie exporters. USD/JPY at 162 remains the elephant in the room: every tick higher raises the probability of verbal intervention from Tokyo. Japanese officials have historically drawn lines near these levels, and any BOJ commentary today could move the Nikkei sharply.

What to Watch Today

• HKEX tech at the open: After the Hang Seng’s 1.59% drop and a 1.32% Nasdaq selloff overnight, Hong Kong tech names face a two-day headwind. Watch Alibaba and Tencent for signs of whether mainland buying through Stock Connect provides a floor.
• USD/JPY intervention watch: With the pair above 162, any comments from Japan’s Finance Ministry or BOJ officials could trigger yen volatility and whip the Nikkei intraday. The last round of verbal warnings came near these levels.
• ASX energy reaction: Oil’s 3% overnight drop hasn’t been priced into the ASX yet. Energy is the second-largest sector weight — expect Woodside, Santos, and Beach Energy to gap lower at 10:00am.
• Taiwan semiconductor momentum: TAIEX gained 1.28% yesterday on chip strength, but overnight weakness in US semis (Micron’s Anthropic deal aside) could test whether TSMC’s rally has legs or was a one-session rotation.

Bottom Line

The overnight setup leans risk-off for Asia’s Tuesday open. A tech-led US selloff, a sharp oil decline, and lingering China weakness from yesterday’s session point to a cautious start — particularly in Hong Kong and on the ASX. Japan could go either way depending on whether USD/JPY at 162 triggers official pushback, while Taiwan’s chip rally faces its first real test against softer US tech sentiment. Luna3 sees this as a session to watch positioning rather than chase direction.
