Asian stock markets surged on Friday, buoyed by overnight gains on Wall Street and a global rally in semiconductor stocks, with renewed optimism surrounding artificial intelligence (AI) investments driving sentiment higher [1]. The South Korean KOSPI Composite led the region, soaring over 14.5%, propelled by significant advances in SK Hynix (up over 25%) and Samsung Electronics (up over 20%) [1]. Investor confidence was further supported by South Korea's announcement of a 20 trillion Won sovereign wealth fund aimed at strategic industries, as well as a 2.3% rise in June industrial production—the fastest monthly increase in six years [1].
Korean authorities responded to heightened market volatility by intensifying policy measures. According to analysts at Commerzbank, the Finance Ministry announced additional steps to curb equity market swings, framing these as part of a broader effort to stabilize markets and support the Korean Won amid sharp movements in the KOSPI and related leveraged products [1].
Elsewhere in Asia, Japan's Nikkei 225 climbed 3.5% to approximately 64,050 after the Bank of Japan (BoJ) voted 8-1 to keep its policy rate unchanged at 1%, with only Hajime Takata dissenting in favor of a rate hike due to inflation risks linked to Middle East conflicts [1]. Chinese markets posted mixed results: the SSE Composite rose 0.70% to about 3,830, and the Shenzhen Component jumped over 3% to 13,700, while Hong Kong's Hang Seng slipped nearly 0.10% to around 25,830 [1].
Economic data from China highlighted ongoing weakness, as the NBS Manufacturing PMI fell into contraction at 49.2 in July (down from 50.3), and the Non-Manufacturing PMI dropped to 49.0, both missing the 50.0 threshold and underscoring growth concerns after sub-target Q2 GDP results [1]. Additionally, Zhongji Innolight's Hong Kong IPO raised HK$53.4 billion but saw the stock fall on debut, reflecting selective caution around tech valuations despite the broader market rally [1].
CONCLUSION
Asian equities rallied strongly, led by a dramatic surge in South Korea's KOSPI on AI optimism and robust Wall Street performance. While policy support and strong earnings fueled gains in Korea and Japan, weak Chinese economic data and selective caution in tech IPOs tempered enthusiasm. Overall, the market reaction was positive, but underlying risks remain in certain sectors.
