Asian stock markets opened mostly higher on Tuesday, 22 September, with technology and semiconductor shares leading gains after a strong session on Wall Street. Lower oil prices also supported sentiment, while investors turned their attention towards upcoming US-China talks and developments surrounding Iran.
Technology leads the advance
MSCI’s broadest index of Asia-Pacific shares outside Japan rose around 0.75% in early trading, reaching a two-week high. Technology stocks were among the strongest performers after renewed enthusiasm for artificial intelligence helped drive US technology shares sharply higher overnight.
South Korea was one of the region’s strongest markets. The Kospi initially gained around 2% before moderating, with semiconductor and technology companies supporting the advance. Taiwan also moved higher and reached record territory during the session.
China and Hong Kong move higher
Mainland Chinese equities opened positively, with the CSI 300 gaining around 0.2%, while Hong Kong’s Hang Seng advanced roughly 0.3% in early trade. Chinese and Hong Kong-listed AI companies were among the stronger sectors.
Investors are increasingly focused on a meeting between US President Donald Trump and Chinese President Xi Jinping expected later this week. Trade, investment and artificial intelligence are likely to be closely watched by markets during the talks.
Tokyo closed for holiday
Japanese markets were closed for a public holiday, removing one of Asia’s largest exchanges from Tuesday’s regional trading. Elsewhere, Australia’s S&P/ASX 200 gained around 0.2% in early dealings.
Oil provides support
Energy prices were another important factor. Brent crude stabilised around $100 a barrel after falling more than 3% in the previous session. Expectations that diplomatic discussions involving the United States and Iran could reduce geopolitical tensions contributed to the decline in oil prices.
Lower energy prices can ease inflation concerns across Asia, particularly for economies heavily dependent on imported oil.
The early session therefore showed a broadly positive tone across Asian markets, led by technology, while investors remained focused on oil prices, monetary policy and the approaching US-China meeting.
