Key Points
Nikkei 225 fell 2,563 yen to 64,024 on June 8, down 3.8%.
US jobs data sparked rate hike fears, with Philadelphia Semiconductor Index falling 10%.
SoftBank Group, Tokyo Electron, and Advantest led Tokyo declines on growth stock selloff.
Iran missile attack added geopolitical risk, pushing crude oil up 2% and weighing on sentiment.
The Nikkei 225 index fell 2,563.52 yen to 64,024.60 on June 8, closing down 3.8% after a shock US employment report triggered rate hike expectations. The decline marks the fourth-largest drop in trading history. AI and semiconductor stocks led the selloff as investors fled growth-focused equities. Rising interest rates make future profits less valuable, pressuring high-growth companies.
US Jobs Data Sparks Global Selloff
On June 5, the US reported 172,000 new jobs in May, beating forecasts and raising expectations for Federal Reserve rate hikes. The Philadelphia Semiconductor Index (SOX) fell 10% that day. This flow directly hit Tokyo on June 8, where the Nikkei dropped as much as 3,100 yen intraday. The US dollar strengthened and Treasury yields rose across all maturities as investors repriced rate expectations.
AI Stocks Face Largest Losses
SoftBank Group (9984.T), Tokyo Electron (8035.T), and Advantest (6857.T) suffered the steepest declines, dragging the broader index lower. These high-growth tech names had surged on data center demand but faced sharp profit-taking. Growth stocks are valued on future earnings discounted at current interest rates. Higher rates increase the discount rate, cutting valuations immediately. The selloff reflects concern that AI enthusiasm may have pushed valuations too far.
Geopolitical Risk Adds Pressure
Early on June 8, Iran launched missiles at Israel, sending crude oil futures up 2% in after-hours trading. WTI crude rose sharply on the geopolitical shock. The combined effect of rate hike fears and Middle East tensions created a risk-off environment. Investors moved away from speculative bets and toward defensive positions. The Tokyo market could not escape the dual headwinds from Washington and Tehran.
What Comes Next
SMD Asset Management expects the Federal Reserve to raise rates 25 basis points in September and December 2026, but not pursue aggressive tightening. Key data to watch include May US consumer prices, the SpaceX IPO, and Micron Technology earnings. If these show stability, the AI and semiconductor selloff may prove temporary. However, if rate hikes accelerate or corporate guidance weakens, the decline could extend further into summer.
Final Thoughts
The Nikkei’s 3.8% drop reflects a sharp repricing of growth stocks on US rate hike fears. With Meyka’s analysis showing AI and semiconductor valuations compressed by rising discount rates, investors should monitor Fed communications and earnings guidance closely before re-entering these sectors.
FAQs
Strong US jobs data on June 5 raised rate hike concerns. Higher rates reduce future profit values, particularly impacting growth and semiconductor stocks, which fell 5-10% across Asia.
SoftBank Group, Tokyo Electron, and Advantest led declines as AI and semiconductor stocks faced profit-taking after surging on data center demand and valuation compression.
