Asian stock markets declined amid growing concerns over the enormous costs of investment in artificial intelligence (AI) and ongoing geopolitical uncertainties. On Monday, October 19, major stock markets in Japan and South Korea recorded notable losses. Meanwhile, international oil prices fell, although investors remained cautious about the global economic outlook.
According to a Reuters report, Japan’s Nikkei index fell by 2%. South Korea’s stock market also declined by 1.6%. The MSCI Asia-Pacific index, excluding Japan, dropped by 0.3%. Concerns about the potential returns from substantial investments in the technology sector, combined with uncertainty surrounding the global economy, weighed on market sentiment.
Investors are paying particular attention to the substantial spending required to develop AI technologies and related infrastructure. Major technology companies are investing heavily in data centres, computing infrastructure, semiconductor chips and electricity systems to expand their AI capabilities. However, questions remain about whether these investments will generate the expected returns.
Analysts suggest that it may take considerable time for companies to realise the full benefits of their AI investments. In the meantime, rising infrastructure costs, interest payments and other operating expenses could put pressure on corporate profitability. Higher government bond yields and increased corporate borrowing costs could also make financing new projects more difficult.
Companies across Asia’s technology sector could also face risks. Several major economies in the region play important roles in the global supply chains for semiconductors, memory chips, electronic components and AI infrastructure. If major technology companies reduce their spending or delay new projects, the revenues and valuations of related manufacturers could come under pressure.
The Reuters report also noted that semiconductor stocks in the United States faced significant selling pressure last week. The impact extended to technology stocks across Asia. Investors are now closely watching upcoming quarterly earnings reports from major technology companies. These results could provide important insights into corporate profitability, future revenue prospects and companies’ ability to sustain their AI investments.
Meanwhile, international oil prices declined on Monday. According to Reuters, Brent crude futures fell by 1.6% to $108.06 per barrel. US crude futures also declined by 0.7% to $100.70 per barrel. The price movements followed a US move concerning the possible easing of certain restrictions on Russia. However, uncertainty over the final outcome meant that the oil market remained vulnerable to further changes.
Geopolitical tensions in the Middle East continued to pose risks to global markets. Reports concerning a mine explosion involving a tanker in the Strait of Hormuz added to investors’ concerns and encouraged interest in safe-haven assets. Any escalation of tensions along this strategically important shipping route could affect international trade, energy supplies and transportation costs.
Despite the decline in Asian stocks, US stock futures showed some positive movement ahead of Monday’s trading session. The S&P 500 futures rose by 0.5%, while Nasdaq futures gained 0.8%. This suggested that expectations for the US market remained relatively positive, even as several Asian markets experienced losses.
Meanwhile, gold prices also moved higher in international markets. Against a backdrop of declining government bond yields, gold rose by 0.4% to $4,181 per ounce. During periods of uncertainty, investors often turn to assets such as gold and government bonds. However, market movements continue to depend on economic data, interest rates and geopolitical developments.
Over the coming days, investors will closely monitor the financial results of major technology companies, their plans for AI infrastructure spending and developments in the energy market. New information on these issues could significantly influence investor expectations. Nevertheless, the recent decline in Asian stock markets should not automatically be interpreted as evidence of a long-term downward trend. The future direction of the markets will depend on actual corporate earnings, the returns generated by investments and the broader global economic outlook.
