The Shock of the Nikkei's Sudden Drop of Over 3,000 Yen: The Trial Brought to the Japanese Economy and the AI Market by the 'Democratic Victory' in the US Midterm Elections
A shockwave ran through the Tokyo stock market. As news of the opposition Democratic Party’s dominance and victory in the US midterm elections broke, the Nikkei Stock Average recorded a historic plunge, with its decline momentarily exceeding 3,000 yen.
The background to the market’s highly sensitive reaction lies not merely in a shift of political power, but in a ‘strong sense of caution regarding stricter regulations surrounding AI (artificial intelligence).’ What kind of ripples will this US political shift spread to Japan’s high-tech industry and the Japanese economy as a whole? We unravel the full picture and its impact.
1. Why did the market fall into a panic over the ‘Democratic victory’?
The primary cause of this sudden drop lies in the Democratic Party gaining strength in the US midterm elections. What market participants were wary of was the concern that moves toward stricter regulation of AI technology and the semiconductor market might accelerate.
-
Headwinds for the AI and semiconductor sectors: The Democratic Party has consistently shown a positive stance toward the ethical use of AI, security-related regulations, and control over platform operators. With them holding the majority, anxiety has spread that there might be a sudden braking effect on related investments.
-
Spillover to the Tokyo market: The Japanese market has previously benefited from the global ‘AI and semiconductor boom,’ with related stocks leading the market. As a result, it was hit directly by the regulatory risk originating in the US, leading to a situation where selling intensified, particularly among high-priced stocks.
2. Concrete impact on the Japanese economy and stock market
Although it was a historic plunge of over 3,000 yen at one point, there were subsequent movements of buying back as excessive uncertainty eased somewhat, such as President Trump expressing congratulations on the election results. However, risks that cannot be ignored remain for the future of the Japanese economy and corporate performance.
-
Re-evaluation of the high-tech and manufacturing supply chain: Japanese machinery, electronic component, and semiconductor-related companies are closely linked to the trends of US tech giants. Changes in US regulations or policy directions could become factors that disrupt the order plans and capital investment forecasts of Japanese companies.
-
Cooling investor sentiment with an eye on the ‘presidential election two years from now’: Voices from the market have also suggested that ‘this result is being viewed as a prelude to the presidential election two years from now, and the US political situation could become a long-term destabilizing factor.’ For the time being, it is highly likely that a market with high volatility, swayed by the tug-of-war in US politics, will continue.
Conclusion: How to face the ‘linkage risk’ of the global economy
This sudden drop has once again highlighted how strongly the Japanese stock market now depends not only on domestic factors but also on the ‘political situation’ and ‘steering of AI policy’ in the United States.
Even if the temporary shock of ‘concerns over AI regulation due to a Democratic victory’ is overcome, the impact that changes in the US political structure have on the global tech ecosystem is profound. Investors and management alike are under intense scrutiny regarding how Japanese companies will maintain and adapt their profit structures in this rapidly changing environment.
