Market Snapshot

What Moved the Market

• Record-High Retreat: The Nikkei hit an intraday high of 66,428.81 on May 27 but closed nearly flat, signaling investor unease despite the index's historic run above 65,000 and toward 66,000. Profit-taking pressure emerged as traders reassessed valuations in the AI-fueled rally.

• AI Momentum Still Intact: Reuters' poll of analysts forecasts the Nikkei will reach 69,000 by end-2027, driven by sustained AI investment gains and robust earnings outlooks. However, the poll also notes the index's blistering pace has made forecasting difficult for market participants.

• Geopolitical Caution: U.S.-Iran peace negotiations continue to influence oil markets and risk sentiment across Asia-Pacific. Declines in crude prices had earlier supported Japanese equity valuations, but uncertainty persists.

Corporate Headlines

SoftBank Reports Five-Fold Profit Gain on AI Investments: Japanese technology investor SoftBank Group posted near-five-fold profit growth for fiscal year through March, powered by its high-yielding artificial intelligence portfolio holdings. The stellar results underpin investor confidence in Japan's tech sector and justify part of the Nikkei's recent surge.

Japanese Megabanks Post Record Profits, but Headwinds Loom: Japan's largest lenders—Mitsubishi UFJ, Sumitomo Mitsui, and Mizuho—reported record profitability, yet analysts warn profit growth may slow due to mounting credit costs and lingering geopolitical risks. The banking sector's strength has been a key pillar supporting the broader market rally.

BOJ & Macro Watch

• BOJ Holds Rates Steady, Eyes June Decision: The Bank of Japan maintained rates at 0.75% at its May meeting while signaling a potential June rate hike by emphasizing inflation overshoot risks. Three board members dissented, reflecting internal debate on policy timing.

• Yen Weakness Persists Amid Policy Divergence: The USD/JPY pair remains elevated in the 150–160 range, reflecting Japan's cautious monetary policy versus U.S. rate resilience. The Ministry of Finance intervened in FX markets in April for the first time in two years to support the yen.

What to Watch Tomorrow

• Corporate earnings releases and guidance revisions from mid-cap companies as first-quarter reporting season advances in Japan
• BOJ official communications and any signaling toward the June monetary policy decision, which will be closely monitored for rate-hike probability
• Asia-Pacific risk sentiment and crude oil price movements, given ongoing U.S.-Iran negotiations and their impact on Japanese equity flows
