TL;DR

Asian equities outside Japan climbed to all-time record highs on Monday, driven by a powerful combination of AI chip momentum in South Korea and Taiwan and easing Iran war anxiety. The MSCI Asia ex-Japan benchmark wiped out losses accumulated since the Strait of Hormuz crisis began, led by SK Hynix and Taiwanese chip stocks. The move sets a constructive tone ahead of the US market open, though active military operations in the Persian Gulf keep cross-asset risks elevated.

What Happened: Asian Stocks Reach All-Time Highs

Asian equity markets ex-Japan reached record highs in Monday's session, according to Bloomberg. The rally drew on two independent forces arriving at the same time: a sustained AI chip demand cycle and improving sentiment around the US-Iran conflict.

South Korean and Taiwanese chipmakers led the advance. SK Hynix, whose first-quarter profit rose five-fold on record demand for high-bandwidth memory (HBM) chips, contributed heavily to the Korean KOSPI's gains. HBM is the specialist memory architecture that AI accelerators and large data center GPUs depend on. The chipmaker recently forecast that AI chip demand would exceed its manufacturing capacity through 2026, according to Reuters.

Samsung shares lagged, with analysts citing strike risk at domestic facilities as a near-term overhang. Taiwan's benchmark also climbed as AI-linked chipmakers benefited from continued global data center investment. The dual catalyst structure, chips plus geopolitics, allowed the MSCI Asia ex-Japan index to decisively reclaim and surpass its pre-war high.

Why Markets Moved

Equities priced in a meaningful reduction of Iran war risk after President Trump announced "Project Freedom," a US military escort mission for neutral ships trapped in the Strait of Hormuz. Brent crude fell more than 2% in early trading before stabilizing below $109 a barrel, well off last week's high above $126. The Iran risk premium that had weighed on global growth expectations since the strait closure began has started to unwind.

Beyond geopolitics, the AI chip cycle provided a structural bid. Global technology investment spending has been resilient throughout the Iran war period, and SK Hynix's results confirmed that demand from hyperscalers and AI hardware providers remains ahead of supply capacity. That combination gave investors a reason to rotate back into Asian tech equities even as the geopolitical situation remains fluid.

Gold dipped as the safe-haven bid eased. Bond yields in developed markets ticked higher in a mild risk-on signal. Currency markets remained relatively calm, with no major dislocations in Asian FX pairs.

Implications for Traders

Equities and Index Futures

The MSCI Asia ex-Japan record has direct implications for US equity futures. A clean break to new all-time highs in Asian markets, driven by credible fundamental catalysts in AI hardware, strengthens the bullish case for US tech and semiconductor names at the open. Micron (MU), which has exposure to the same HBM demand wave as SK Hynix, and names across the semiconductor supply chain are worth watching. The iShares MSCI South Korea ETF (EWY) offers diversified exposure to SK Hynix and Samsung.

Oil and Commodity Futures

Brent below $109 is a positive input for equities and a headwind for energy sector earnings. Further de-escalation in the Hormuz situation could push crude lower still. However, the active military operation in the strait keeps oil directionally uncertain on an intraday basis. The downside case for oil requires a formal ceasefire and confirmed re-opening of the waterway to commercial traffic.

Crypto

Bitcoin and Ethereum typically benefit from risk-on shifts in global macro conditions. If Asian equity strength carries through to US pre-market trading, crypto assets may see incremental upside. The structural AI and tech narrative that drove Monday's Asian gains is broadly positive for technology-adjacent risk assets, including large-cap crypto.

Potential Positives vs Negatives

Positives

  • MSCI Asia ex-Japan at a new all-time high is a strong signal that institutional capital is rotating back into risk, not out of it.
  • SK Hynix's record earnings and forward guidance confirm the AI memory upcycle is real, not speculative, providing a fundamental floor under Korean and Taiwanese tech valuations.
  • Lower oil prices, if sustained, reduce global cost pressures and give central banks a cleaner path toward rate cuts.
  • A successful Project Freedom operation would set a precedent for further normalization of Hormuz shipping, removing a persistent drag on global growth.

Negatives

  • The Iranian ceasefire violation warning and a tanker strike reported Monday morning mean the Hormuz situation is not resolved. Equity gains could reverse quickly if escalation resumes.
  • Samsung's underperformance relative to SK Hynix signals that the AI chip rally is concentrated rather than broad-based. Single-stock or sector concentration risk is present in Korean equities.
  • A sustained rally in Asian equities while the US was closed overnight could lead to a "sell the open" dynamic in US markets if geopolitical risk re-surfaces before the bell.
  • AI chip demand that exceeds manufacturing capacity may eventually cause supply bottlenecks, posing a longer-term ceiling on hardware-driven equity gains.

What Could Happen From Here

Base Case (Most Likely)

The MSCI Asia ex-Japan record holds. US equity futures open positive, with semiconductor and AI hardware names outperforming. Brent stays in the $105 to $115 range. The AI chip cycle continues to drive earnings upgrades for HBM-focused names. Confirmed when: US pre-market futures add to Asian gains, SK Hynix closes at or near session highs, Brent holds below $112 through the New York open.

Upside Case

A formal Iran ceasefire removes the remaining geopolitical overhang entirely. Global equities surge broadly as inflation risk, supply chain disruption, and energy cost pressures recede simultaneously. AI chip stocks extend gains as capital reallocates from safe havens into growth. Confirmed when: ceasefire agreement is announced, US naval blockade lifted, oil drops toward $95 to $100, and major equity indices break above multi-month resistance levels.

Downside Case (Escalation)

Iran escalates in response to Project Freedom, challenging US escort vessels or striking additional tankers. Risk-off returns. Asian equity gains reverse, oil spikes back above $120, and safe-haven assets including gold and US Treasuries rally. The AI chip tailwind is not enough to offset a broad geopolitical risk repricing. Confirmed when: Iranian military action is confirmed against US assets, or peace talks are formally suspended.

What to Watch Next (Next 24 Hours)

  • US equity futures and the S&P 500 open to gauge whether Asian gains translate to New York
  • Semiconductor sector ETFs (SOXX, SMH) for follow-through on the AI chip momentum
  • SK Hynix and Samsung intraday and closing prices for confirmation of the Korean rally's breadth
  • Brent crude settlement as a read on how traders are pricing the Hormuz situation post-Project Freedom
  • Any official statements from Iran or the US on ceasefire progress or Project Freedom outcomes (see our Hormuz Oil Risk Watch for the full escalation analysis)
  • Broader MSCI Emerging Markets benchmark performance relative to the Asia ex-Japan record

Frequently Asked Questions

Why are Asian stocks hitting records while the Iran war is ongoing?
Two forces converged on Monday: improving Iran peace talk signals reduced geopolitical risk, and AI chip companies in Korea and Taiwan reported strong earnings that confirmed the technology demand cycle. Markets are forward-looking, and both developments gave institutional investors reasons to add risk.

What is high-bandwidth memory (HBM) and why does it matter for stock prices?
HBM is a specialized type of memory chip stacked on top of AI processors to enable faster data transfer at lower power. It is essential for training and running large AI models. SK Hynix dominates HBM production, so when AI data center spending rises, SK Hynix profits rise. Its five-fold earnings jump in Q1 2026 reflects exactly that demand surge.
