Asia’s stock markets delivered a historic session on Monday as South Korea’s tech shares surged on an AI investment landmark — Google announcing its first non-U.S. AI campus in Seoul — while Japan’s Nikkei 225 closed above 60,000 for the first time in its 76-year history. Chinese equities extended a multi-week recovery on Trump-Xi summit optimism, and solid macro data across the region reinforced the risk-on mood. Elevated oil prices — with Brent crude holding above $106 — remained an undercurrent from the ongoing Iran War, but were insufficient to derail one of Asia’s strongest sessions of 2026.
South Korea: KOSPI and KOSDAQ Rally as Google Picks Seoul for First Non-U.S. AI Campus
South Korean stocks surged on Monday as money continued flowing into technology shares, according to Nikkei Asia. The KOSPI advanced, extending a run that had already produced a record-high session on April 21, when the index jumped 2.7% to an all-time high on semiconductor strength.
Monday’s catalyst was structural: Google announced it will build its first AI campus outside the United States in South Korea — a landmark endorsement of Korea’s semiconductor infrastructure and AI talent ecosystem.
The announcement amplifies an already powerful earnings story. SK Hynix reported Q1 2026 net profit of ₩37.6 trillion (~$25.4 billion), a nearly fivefold year-over-year jump at a 72% operating margin — the highest in the company’s history — as demand for High Bandwidth Memory chips used in AI accelerators remains insatiable. Industry analysts project the AI-driven memory shortage will persist through 2027. South Korea’s macro backdrop is equally supportive: Q1 2026 GDP returned to growth on chip exports, and Korean exports hit an all-time high by value.
The KOSDAQ — Korea’s growth-stock exchange — also advanced, reflecting broad-based risk appetite rather than a narrowly concentrated rally.
Japan: Nikkei 225 Sets All-Time Closing Record at 60,537
Japan’s benchmark Nikkei 225 gained 821.18 points (+1.38%) to close at 60,537.36 — the highest closing level ever recorded, according to Nikkei Asia. The index surpassed the 60,000 threshold on a closing basis for the first time, extending a rally that has taken Japanese equities from the 42,000s of mid-2024 to uncharted territory.
Two structural tailwinds drove the advance:
- BOJ policy stability: The Bank of Japan is expected to hold its benchmark rate unchanged at next week’s meeting, with June identified as the next potential window for a hike, per Nikkei Asia. A steady BOJ policy rate keeps the yen under moderate pressure — USD/JPY at 159.16 — translating into stronger yen-adjusted earnings for Japan’s export-heavy index.
- Corporate earnings momentum: Nissan flipped to a positive operating profit forecast for fiscal 2025, while Daiwa Securities Group agreed to acquire Orix Bank for $2.3 billion.
Note: Japanese markets close for Golden Week from April 29 through May 5.
China: CSI 300 Extends Recovery on Summit Optimism and Solid Macro Data
Chinese equities extended their multi-week recovery. The CSI 300 has climbed over 8% from its March low as investors position for a U.S.-China trade thaw, with the South China Morning Post reporting that a Trump-Xi summit is tentatively scheduled for May 14–15. The Shanghai Composite gained 6.44 points (+0.15%) to close at 4,086.34.
Macro data reinforced the cautiously optimistic mood:
- China’s industrial firm profits rose 15.8% year-on-year in March and 15.5% in Q1 2026, per Reuters.
- Moody’s revised its outlook on China’s economy from negative to stable, Reuters reported.
- Shenzhen’s ChiNext index hit a record high after regulator reforms energized growth-stock investors.
- DeepSeek unveiled its V4 AI model, intensifying competition with U.S. frontier AI labs.
One headwind: Hengli Petrochemical shares plunged after Washington imposed fresh Iran oil sanctions, while Beijing warned Washington against the “misuse of sanctions”.
Hong Kong’s Hang Seng edged down 52.42 points (−0.20%) to 25,925.65, dragged by energy-sector pressure.
Macro Context: Iran War, Oil, and the Disconnect Tension
Asia’s equity markets are navigating a striking paradox: indices at or near record highs while the Iran War keeps energy costs elevated. Nikkei Asia’s “Asia’s Great Disconnect” analysis notes that markets are booming even as the conflict fuels a cost-of-living crisis across the region.
- Brent crude rose 0.83% to $106.20/bbl as shipping traffic through the Strait of Hormuz remains muted, per Reuters.
- Gold (XAU/USD) slipped 0.46% to $4,700.50/oz.
- The U.S. 10-year Treasury yield ticked up to 4.316%; Japan’s 10-year JGB yield rose to 2.474%.
- Previous U.S. session: S&P 500 +0.80%, Nasdaq +1.63% — positive handoff to Asian risk assets.
Other Asian Markets
- India Sensex: Rose 639.42 points (+0.83%) to 77,303.63, supported by domestic earnings strength. Sun Pharma’s $11.75 billion acquisition of Organon highlighted the industry’s pivot beyond generics.
- Singapore STI: Fell 30.13 points (−0.61%) to 4,892.73, dragged by energy and commodity-linked stocks.
- Australia ASX All Ordinaries: Edged down 0.17% to 8,990.80. ANZAC Day (April 25) fell on a Saturday — no closure on Monday; the market was fully open.
