Asian stocks mostly advanced Wednesday as renewed strength in technology and semiconductor shares boosted markets in South Korea and Japan. However, higher oil prices and uncertainty surrounding U.S.-Iran negotiations kept investors cautious ahead of key U.S. inflation data.

South Korea’s KOSPI led regional gains, surging more than 4%, supported by a powerful chip-stock rally. Samsung Electronics jumped over 7%, while SK Hynix gained around 7% amid reports that Singapore state investor Temasek is considering direct investments in both semiconductor companies.

AI optimism also strengthened after CoreWeave reported better-than-expected sales growth, sending its shares sharply higher in extended U.S. trading. Super Micro Computer also gained after issuing a revenue forecast above expectations. Meanwhile, Nvidia announced partnerships with six major financial institutions aimed at mobilizing more than $500 billion in third-party capital for AI infrastructure.

Japan’s Nikkei 225 gained about 0.5%, with semiconductor-related stocks including Kioxia Holdings, TDK and Murata Manufacturing advancing. Chinese markets also moved higher, with the CSI 300 rising roughly 0.6% and the Shanghai Composite adding around 0.2%. SMIC, Cambricon Technologies, Luxshare Precision and NAURA Technology were among the notable technology gainers.

Hong Kong bucked the regional trend. The Hang Seng fell more than 1% as major technology stocks Alibaba, Tencent, NetEase, JD.com and Meituan declined.

Elsewhere, Australia’s S&P/ASX 200 dropped around 0.7% after the Reserve Bank of Australia maintained its cash rate at 4.35%. Indian and Singaporean stocks also traded lower.

Oil prices remained another key market concern as uncertainty over the Strait of Hormuz continued. Brent crude extended its rally to a sixth consecutive session, trading near $89.44 per barrel amid ongoing tensions between Washington and Tehran.

Investors are now focused on the U.S. Consumer Price Index report. July headline CPI is forecast to rise 0.1% month-on-month and 3.4% annually, while core inflation is expected at 2.5% year-on-year. A softer U.S. inflation reading could reduce pressure on the Federal Reserve as markets weigh interest-rate risks against rising energy costs.
