Japan Morning Briefing: What to Watch on September 29, 2026
Tokyo investors face a cautious start to Tuesday’s session as geopolitical tensions and AI bubble concerns weigh on global risk sentiment. Overnight weakness on Wall Street, combined with a strengthening yen, sets up a challenging backdrop for Japanese equities as the TSE prepares to open.
Wall Street Weakness Pressures Asian Markets
US markets closed broadly lower Monday, with the S&P 500 falling 0.74% to $765.61, while the Nasdaq 100 dropped 1.07% to $736.53. The Dow Jones declined 0.67% to $514.02. Higher oil prices and rising Treasury yields pressured stocks, while Michael Burry’s warning that the AI bubble “may burst” sooner than expected added to tech sector concerns. Geopolitical developments around Iran-US tensions and ongoing Middle East diplomatic efforts contributed to market uncertainty.
Yen Strength Challenges Export Giants
USD/JPY sits at ¥157.49, representing continued yen strength that could pressure Japan’s export-heavy sectors. Toyota, Sony, and other multinational corporations may face headwinds from the stronger yen, which reduces the value of overseas earnings when converted back to Japanese currency. This currency dynamic will be particularly important for NISA investors holding export-focused funds or individual stocks.
Key Themes and Sectors to Monitor
Technology stocks warrant close attention following Burry’s AI bubble warning, with SoftBank Group and other tech-exposed names potentially under pressure. Energy companies like Inpex may benefit from higher oil prices amid Middle East tensions. Defensive sectors including utilities and consumer staples could attract safe-haven flows. Watch for any Bank of Japan commentary on currency intervention, as USD/JPY remains near intervention-sensitive levels.
Today’s session will test whether Tokyo can decouple from overnight weakness or if global risk-off sentiment dominates the open.
