- KOSPI plunged 5.1% — the sharpest single-session drop across Asia — while Nifty 50 surged 1.6% and NZX gained 1.5%, splitting the region into clear winners and losers
- Overnight US tech rally (Nasdaq +3.4%, XLK +5.0%) after the momentum crash recovery should lift TAIEX and HKEX tech names at the open
- WTI oil collapsed 6.3% on the US-Iran accord, pressuring energy exporters while handing a cost tailwind to import-heavy economies like Japan, India, and South Korea
Where Asia Closed Yesterday
South Korea was the story. KOSPI cratered 5.1% in a single session — the worst day for the index in months — dragging it to 6,257 while every other major market posted either a modest move or outright strength. No other Asian benchmark lost more than 1%.
Japan’s Nikkei 225 slipped 0.9% to 63,755, weighed by yen weakness and cautious positioning ahead of the US session. China was split: the Hang Seng eked out a 0.5% gain to 26,009, but mainland boards went the other way — Shanghai Composite fell 0.6% to 3,810 and Shenzhen Component dropped 1.0% to 13,448. The Hong Kong-mainland divergence suggests offshore capital is still finding selective value in HK-listed tech and financials while onshore sentiment stays fragile.
The bright spots were clear. India’s Nifty 50 jumped 1.6% to 24,774 — the strongest close in the region — as domestic flows continued to support large-cap names. New Zealand’s NZX 50 gained 1.5% to 13,977. Taiwan’s TAIEX added 0.6% to 43,386, holding firm despite the semiconductor supply chain overhang that hit Korea hard. Singapore’s Straits Times dipped just 0.3%, staying largely sidelined.
US Overnight Snapshot
Wall Street roared back. The S&P 500 climbed 1.8% to fresh highs, and the Nasdaq surged 3.4% as investors who held through the recent momentum crash were rewarded in full. The Russell 2000 gained 1.9%, confirming broad participation rather than a narrow tech-only bid.
Technology was the engine — XLK jumped 5.0% on the session, with AMD’s Helios rack announcement adding fuel to the AI infrastructure trade. Materials rallied 1.9% and Financials added 0.9%. Energy was the sole laggard, slipping 0.5% as oil collapsed (more below).
VIX ticked up 4% to 16.5. That’s still well below the panic threshold, but rising vol alongside rising equities is worth noting — options traders are chasing the rebound with leveraged upside bets, which can amplify reversals if sentiment shifts. For Asia, the Nasdaq +3.4% print should put a floor under TAIEX semiconductors and HKEX tech at the open.
Commodity + FX Watch
Oil is the headline. WTI crude crashed 6.3% to $75.30 after ConocoPhillips declined on reports of a US-Iran accord — a potential supply shock that hammered the entire energy complex. For Asia, this is a double-edged move: bearish for ASX energy names and Malaysian oil producers, but a meaningful cost tailwind for net importers like Japan, India, and South Korea. Korean refiners and airlines could catch a bid today off the back of cheaper feedstock.
Gold surged 2.6% to $4,140, reflecting safe-haven demand even as equities rallied — a rare dual bid that often signals uncertainty about the durability of the risk-on move. Copper added 1.8%, which should support ASX base-metal miners like BHP and South32.
On FX, AUD/USD slipped 0.7% to 0.70 — a headwind for Aussie exporters priced in USD terms. USD/JPY edged up to 158, keeping the yen weak and helping Japanese exporter earnings translations but raising intervention talk again.
What to Watch Today
- KOSPI follow-through: After a 5.1% wipeout, the open in Seoul is the single most important print today. Watch whether institutional buying materialises or if selling accelerates into a second session. Samsung and SK Hynix set the tone for the entire Korean tech complex.
- HKEX tech gap: The Nasdaq’s 3.4% surge and XLK’s 5.0% jump should translate directly to Alibaba, Tencent, and Meituan at the Hong Kong open. The Hang Seng already closed green yesterday — a US tech tailwind could extend that streak.
- Oil-to-energy transmission: With WTI down 6.3%, ASX energy names (Woodside, Santos) face selling pressure at the open. Conversely, Indian OMCs and Korean airlines could rally on cheaper crude.
- Yen intervention watch: USD/JPY at 158 with the yen grinding weaker again puts the pair back in the zone where Japan’s MoF has historically stepped in. Any verbal or actual intervention would send the Nikkei sharply in either direction.
Bottom Line
The overnight US session hands Asia a clear risk-on signal — broad-based equity gains, surging tech, and strong commodity metals. But the region walks into Wednesday split: India and Taiwan carry upward momentum, Korea needs to stabilise after a 5% shock, and Japan is caught between a weak yen tailwind and the threat of intervention. The oil crash reshuffles sector positioning across every exchange. Luna3 sees a net-positive open for most of the region, with Korea as the wildcard that could swing sentiment either way.
