What Moved the Market
- National Holidays: The TSE is observing a three-day closure starting September 21, coinciding with Respect for the Aged Day and the Autumnal Equinox Day, which impacts liquidity and cross-border arbitrage strategies.
- Yen Weakness Post-BOJ: The Japanese yen continued to drop against the US dollar following the Bank of Japan's decision to raise rates on September 18, as Governor Kazuo Ueda's mixed signals about future hikes fell short of hawkish expectations.
- Regional Asian Sentiment: While Japan is closed, other Asia-Pacific markets edged higher, buoyed by AI demand for chips and easing oil prices amid reports of increased Middle East supply flows.
Corporate Headlines
No new Japanese corporate earnings or major business announcements were released today due to the market holiday. Recent notable context includes SoftBank Group overtaking Toyota as Japan’s most valuable company in June 2026, a milestone driven by the global AI boom.
BOJ & Macro Watch
- Policy Stance: The BOJ raised rates as expected on September 18, but the yen weakened as Governor Ueda signaled uncertainty regarding the pace of future tightening. Strategists warn that supporting the yen will require more aggressive communication on tightening.
- Fed Impact: The Federal Reserve's recent "hawkish hike" has raised the bar for the BOJ, with analysts noting that the yen could weaken further unless officials convince markets that more tightening is imminent.
What to Watch Tomorrow
- Market Reopening: Traders should monitor the gap between Nikkei futures and spot prices when the Tokyo market reopens on Thursday, September 24, after the three-day break.
- Global Macro Events: Investors are assessing renewed Middle East hostilities and their impact on oil prices, which have been a key driver for Asian equities this week.
