Asian equity markets generally rose on Wednesday as softer-than-anticipated U.S. inflation figures trimmed expectations for an immediate Federal Reserve rate increase. Although Wall Street closed higher overnight and U.S. futures traded up in Asian hours, escalation in Middle East tensions kept investors cautious and limited the scope of gains.
Market moves and drivers
Japan’s Nikkei 225 climbed 1.0%, while the broader TOPIX index added 0.5%. South Korea outperformed peers, with the KOSPI jumping roughly 7% as major semiconductor names rallied sharply. SK Hynix (KS:000660) surged nearly 13% after its American depositary receipts rose strongly overnight, and Samsung Electronics (KS:005930) gained about 8% amid reports the company reviewed plans for an American listing.
The immediate market response followed U.S. inflation data released on Tuesday that showed headline consumer prices fell 0.4% in June - the first monthly decline since the pandemic - while core inflation remained at 2.6%, below expectations. The data prompted traders to dial back bets on a rate increase by the Fed this month, pushing Treasury yields lower and supporting gains on Wall Street, especially in technology stocks.
Despite those positives, investor sentiment was restrained by geopolitical developments after U.S. President Donald Trump warned of additional military action against Iran and kept a U.S. blockade in place on Iranian-linked shipping through the Strait of Hormuz. Oil prices hovered near one-month highs, raising the prospect that higher energy costs could feed back into inflation dynamics.
China growth and regional breadth
China’s equity benchmarks were mixed. The Shanghai Composite and the blue-chip Shanghai Shenzhen CSI 300 each slipped about 0.3%, while Hong Kong’s Hang Seng rose 1.5%.
New data showed China's gross domestic product expanded 4.3% year-on-year in the April-June quarter, down from 5.0% in the first quarter and below the expected 4.5% pace. June activity indicators were mixed: industrial output rose 5.3% and retail sales increased 1.0%, both beating forecasts. However, fixed-asset investment fell 5.7% in the first half of the year, and property investment dropped 18%, underscoring ongoing weakness in the real estate sector.
Other regional markets
Australia’s S&P/ASX 200 edged up 0.3%, and Singapore’s Straits Times Index climbed 1.2%. Futures tied to India’s Nifty 50 were largely flat in Asian trading.
Overall, the market reaction combined relief from softer U.S. inflation data with persistent caution driven by geopolitical concerns and uneven domestic growth in China. Technology and semiconductor names led strength in parts of the region, while real estate-related indicators in China continued to weigh on sentiment there.
