  • KOSPI surged 5.2% and Nikkei jumped 5% on Monday — the question is whether Asia can hold those gains after a tech-heavy US selloff overnight
  • Nasdaq dropped 1.15% with XLK down 2.8%, signaling pressure on TAIEX semis and HKEX tech names at the open
  • WTI crude collapsed 6% on US-Iran peace deal headlines — energy exporters face headwinds while oil-importing economies like India, Japan, and Korea get a tailwind

Where Asia Closed Yesterday

Monday was a broad-based green sweep across the region, but two markets stood out by a wide margin. The KOSPI surged 5.20% to 8,545 — its strongest session in months — while the Nikkei 225 rallied 4.99% to 69,317, pushing deeper into record territory. Both moves reflected aggressive risk appetite fueled by semiconductor optimism and a weaker yen supporting Japanese exporters.

China’s mainland markets joined the party with the Shenzhen Component up 3.79% and the Shanghai Composite gaining 1.61% to 4,096. The divergence between Shenzhen and Shanghai suggests tech and growth names led the rally over state-heavy large caps. The Hang Seng added a more modest 0.50% to 24,842 — Hong Kong lagged the mainland, which often signals caution among international investors even as domestic flows run hot.

The TAIEX climbed 2.78% to 45,396, riding the same chip-cycle wave as Korea. Australia’s ASX 200 gained 1.25%, Singapore’s STI rose 1.02%, and India’s Nifty 50 added 0.98%. Even New Zealand’s NZX 50 eked out a 0.11% gain. Every major index in the region closed higher — a clean sweep that now faces its first real test from what happened in New York overnight.

US Overnight Snapshot

Wall Street threw cold water on the Asia rally. The S&P 500 fell 0.57% and the Nasdaq Composite dropped 1.15%, with the tech-heavy XLK sector down 2.79% — the sharpest single-sector decline of the session. The “MANGOS” narrative is gaining traction as fund managers rotate out of mega-cap tech; one prominent manager publicly booted Tesla from his version of the Magnificent Seven, and Madison Capital sold its Accenture position citing AI-related concerns.

The rotation was visible in sector performance: Financials (XLF) rallied 1.47% and Materials added 0.42%, while Technology and Energy both fell. VIX ticked up to 16.4 (+1.30%) — elevated relative to last week but still below the 20 stress line. The Russell 2000 lost 0.87%, so there was no small-cap safe haven either. For Asia, the XLK selloff is the number to watch — it maps directly onto TAIEX semiconductor names and HKEX-listed tech.

Commodity + FX Watch

The biggest overnight move was in crude. WTI collapsed 6.03% to $75.90 on headlines of a US-Iran peace deal — the kind of supply-side shock that reshuffles the entire Asian energy complex. Net oil importers like Japan, South Korea, and India benefit directly from cheaper crude, while ASX-listed energy producers and Malaysian O&G names face selling pressure.

Gold climbed 0.58% to roughly $4,350 as the dollar weakened on the same Iran deal headlines — supportive for ASX gold miners like Newmont and Northern Star. Copper was flat (+0.17%), offering no directional signal for base-metal miners. On FX, AUD/USD was essentially unchanged at 0.707 and USD/JPY nudged up 0.10% to 160 — the yen staying weak keeps tailwinds in place for Nikkei exporters, though the 160 level itself invites BoJ jawboning risk.

What to Watch Today

  • TAIEX semiconductor open: TSMC and its supply chain rallied nearly 3% on Monday, but with XLK down 2.8% overnight, expect gap-down pressure on chip names. Whether TAIEX can defend Monday’s gains or gives them back sets the tone for the entire region’s tech sector.
  • Crude oil pass-through: A 6% WTI crash is material. Watch for immediate selling in Woodside Energy (ASX), CNOOC (HKEX), and Reliance Industries (NSE), while airline and transport stocks across the region should catch a bid.
  • KOSPI follow-through test: A 5.2% single-session surge invites profit-taking. If Korean markets open flat-to-down despite broad regional strength on Monday, it signals the move was technical rather than fundamental — which matters for positioning over the rest of the week.
  • US-Iran deal flow-through: Beyond crude, the dollar weakness tied to the deal supports emerging-market Asian currencies. Watch USD/KRW and USD/INR — any meaningful weakening extends the carry trade tailwind for Korean and Indian equities.

Bottom Line

Monday’s Asia sweep was the strongest coordinated regional rally in weeks, but tonight’s US tech selloff and the crude oil crash create a mixed setup. The balance tips slightly risk-off for tech-heavy markets like TAIEX and HKEX, while oil importers — Japan, Korea, India — get an unexpected tailwind from cheaper crude that could offset the Wall Street drag. Luna3 sees a session of internal rotation rather than broad direction: energy out, transport and consumer in, semiconductors on watch.
