Where Asia Closed Yesterday

Monday was rough across most of the region, and South Korea took the worst of it. The KOSPI dropped 3.12% to 6,696.96 — the sharpest single-day decline in the region — dragging chipmakers and auto exporters lower. Taiwan’s TAIEX fell 1.02% to 44,762.32, suggesting the semiconductor complex was under broad pressure.

Greater China wasn’t spared. The Hang Seng slid 1.89% to 25,517.33 as Hong Kong-listed tech and property names sold off. On the mainland, the Shenzhen Component dropped 2.13% to 13,794.29, while the Shanghai Composite gave up 0.59% to 3,882.01. The Shenzhen-Shanghai divergence points to growth and small-cap names bearing the brunt versus the state-heavy large-cap board.

Japan’s Nikkei 225 fell 0.74% to 65,528.09 — a more measured decline, though exporters remain sensitive to yen moves. India’s Nifty 50 and Singapore’s Straits Times Index barely moved, each off less than 0.2%.

The outliers were the Antipodean markets. Australia’s ASX 200 closed up 0.49% at 9,103.10, helped by materials strength, while New Zealand’s NZX 50 added 0.74% to 13,985.00. In a sea of red, the commodity-linked economies held their ground.

US Overnight Snapshot

Wall Street offered a calmer session than Asia delivered on Monday. The S&P 500 rose 0.32% and the Nasdaq Composite gained 0.66%, with tech stocks doing the heavy lifting — XLK added 0.94%. The Russell 2000 climbed 0.42%, a sign that risk appetite extended beyond mega-cap names.

The VIX fell 2.52% to 15.4, well below any stress threshold. This is a market that isn’t pricing in near-term trouble. For Asia, the Nasdaq bounce should provide some relief to the semiconductor-heavy boards in Seoul and Taipei that were hammered on Monday. KOSPI and TAIEX bears may struggle to extend the selloff if US tech holds these levels.

The weak spot was energy — XLE dropped 1.66%, dragged by the oil collapse (more on that below). Materials were flat. Financials barely moved at +0.15%.

Commodity + FX Watch

The overnight commodity picture is split. WTI crude collapsed 4.67% to $81 — a sharp move that will pressure energy stocks across the region, particularly on the ASX (Woodside, Santos) and in Southeast Asian markets tied to oil revenue. Any continuation below $80 would shift the narrative toward demand destruction fears.

On the other side, gold surged 1.90% and copper gained 1.69%. Gold above $4,700 supports ASX gold miners (Newmont, Northern Star) and signals persistent hedging demand. Copper’s strength is a tailwind for BHP and Rio Tinto, and offers a read that industrial demand expectations haven’t collapsed despite the oil rout.

On FX, AUD/USD slipped 0.23% to 0.715 — modest weakness, but the Aussie is holding above its recent range lows. USD/JPY was flat at 159, which removes any yen shock catalyst for Japanese equities today. The yen staying pinned near 159 keeps the status quo for Nikkei exporter earnings expectations.

What to Watch Today

• KOSPI bounce or breakdown: Monday’s 3.12% drop demands a verdict today. If Seoul’s semiconductor and battery names stabilise, it suggests Monday was a liquidity event rather than the start of something worse. Samsung and SK Hynix price action in the first hour will set the tone for the entire tech complex.
• Oil fallout in energy names: WTI’s near-5% overnight drop is the kind of move that cascades into Asian energy stocks at the open. Watch CNOOC and PetroChina on HKEX, Woodside and Santos on the ASX, and Reliance on the NSE for the first read on whether markets are pricing in further downside or treating this as an overshoot.
• China sentiment check: Shenzhen’s 2.13% drop outpacing Shanghai’s 0.59% suggests growth-stock selling. If mainland markets open weak again, it shifts attention back to whether Beijing delivers any policy support before month-end.
• ASX gold and copper miners: With gold up 1.9% and copper up 1.7% overnight, the ASX materials sector has a clear tailwind. Monday’s 0.49% ASX gain could extend if miners open strong — this is where the overnight setup is most directly positive for the region.

Bottom Line

The overnight US session hands Asia a mildly positive setup — tech gains and a low VIX suggest Monday’s regional selloff was more about local positioning than a global risk event. The clear dividing line today is sector exposure: commodity miners and tech names have a green light from overnight price action, while energy-linked stocks face headwinds from oil’s sharp drop. Luna3 sees the balance tilting cautiously risk-on for the Wednesday session, with the KOSPI’s opening print as the early signal for whether Monday’s damage extends or reverses.
