Asia markets rally as tech optimism lifts sentiment

September 23, 2025 (MLN): Asian markets climbed on Tuesday, tracking gains on Wall Street fueled by renewed enthusiasm for technology stocks following Nvidia’s partnership with OpenAI.

Taiwan’s benchmark Taiex led regional advances, jumping 1.32% to close at a record high.

The rally came amid broader optimism in the tech sector and strong investor sentiment across Asia.

South Korea’s Kospi rose 0.69%, while the smaller-cap Kosdaq added 0.28% at the open. Australia’s S&P/ASX 200 edged up 0.17%, and mainland China’s CSI 300 gained 0.31%.

However, Hong Kong’s Hang Seng Index bucked the regional trend, slipping 0.34% at the open.

The city is bracing for the impact of Super Typhoon Ragasa, which is expected to make its closest approach to the Pearl River Estuary on Wednesday morning.

The Hong Kong Observatory has warned that conditions will deteriorate throughout Tuesday, according to CNBC.

Japanese markets remained closed for a public holiday.

In India, tech stocks remain in focus after falling on Monday in response to new U.S. visa policies. Former President Donald Trump made a $100,000 fee for new H-1B visas late Friday, a move that could heavily impact Indian IT firms. Indian nationals accounted for 71% of the nearly 400,000 H-1B visas issued in 2024, according to U.S. government data.

Meanwhile, Singapore is set to release its August inflation data later in the day, which could offer further insight into the region’s economic outlook.

The positive momentum in Asia followed a strong session on Wall Street. The S&P 500 climbed 0.44% to close at 6,693.75, while the Nasdaq Composite rose 0.70% to finish at 22,788.98.

The Dow Jones Industrial Average added 66.27 points, or 0.14%, to end at 46,381.54. All three major U.S. indexes hit fresh intraday and closing record highs, driven by optimism surrounding AI and semiconductor stocks.
