Market Snapshot

What Moved the Market

• Record-breaking milestone: The Nikkei 225 closed at 66,329.50 on Friday, marking the first time the benchmark has traded above the 66,000 level, driven by renewed optimism surrounding potential Iran ceasefire negotiations and reduced geopolitical tensions that have weighed on oil prices.

• AI and earnings momentum: Semiconductor and technology stocks continued to fuel the rally, with investor confidence bolstered by strong corporate earnings results and Japan's status as a prime beneficiary of global AI investment trends. Foreign capital inflows have accelerated as Warren Buffett's recent endorsement and the SoftBank OpenAI connection reinvigorated interest in the Japanese market.

• Analyst confidence on upside: Reuters polling data indicates analyst consensus for the Nikkei to reach 69,000 in 2027, suggesting the current rally remains underpinned by fundamental earnings growth and AI sector tailwinds rather than pure speculation.

Corporate Headlines

SoftBank Group posts record profits as OpenAI holdings surge: SoftBank Group Corporation reported its largest annual net profit in company history, with AI investments—particularly its stake in OpenAI—driving exceptional returns. The company's share price has surged over 58% in recent trading sessions, reflecting investor enthusiasm for Japan's emerging AI champion.

Toyota posts Q4 2026 results with mixed performance: Toyota Motor Corporation reported fourth-quarter earnings showing a 1.89% year-on-year rise in revenue, though net profit missed analyst expectations by a wide margin due to U.S. tariff pressures that drove a 49% decline in earnings. The automaker announced a 95-yen dividend and a 3.66 trillion yen share repurchase program.

Japan's megabanks post record profits but face growth headwinds: Sumitomo Mitsui, Mizuho, and Mitsubishi UFJ reported record profitability for the fiscal year, though analysts caution that elevated credit costs and mounting geopolitical risks may pressure future growth. The banking sector's strong performance reflects higher net interest margins and robust lending demand.

BOJ & Macro Watch

No recent BOJ policy announcements or yen movement data were available for the 24-hour period ending 2026-05-30. The central bank's most recent decision (April 28) held rates steady, with market expectations for a potential June rate hike amid inflation concerns.

• Global macroeconomic data: U.S. economic indicators and further Iran ceasefire developments will be closely watched, as oil price movements and geopolitical risk sentiment remain key drivers of Japanese equity flows.
