Asian equities largely traded flat on Wednesday as market participants balanced concerns about inflationary impacts stemming from the Iran conflict with anticipation around an upcoming U.S.-China diplomatic meeting. Risk appetite was uneven across the region, with South Korea’s benchmark index posting the strongest gains amid a rally in semiconductor stocks.
KOSPI rebound driven by chipmakers
South Korea’s KOSPI led regional markets, climbing 1.4% to claw back losses experienced the prior session and moving back toward the record highs seen earlier in the week. The bounce was powered by renewed strength in chipmaking names after media reports indicated that NVIDIA Corporation (NASDAQ:NVDA) CEO Jensen Huang would be part of the U.S. presidential delegation to China. The report helped firm sentiment toward semiconductor suppliers and equipment makers.
Earlier profit-taking had weighed on the index, particularly among heavyweight names such as Samsung Electronics Co Ltd (KS:005930), following news that talks to avert a strike at a major chipmaking plant had reportedly collapsed. That caution was countered by a surge in rival SK Hynix Inc (KS:000660), which rose about 4% on the same reports that cited NVIDIA’s CEO joining the delegation.
There had also been some investor unease tied to speculation the government might distribute public dividends based on artificial intelligence profits. Officials later clarified the proposal would not amount to a windfall tax on local companies, removing at least one source of policy-related uncertainty for domestic shares.
Regional tone mixed ahead of summit
Markets in Asia took a soft lead from Wall Street after a hotter-than-expected U.S. consumer inflation reading revived worries over the broader inflationary consequences of the Iran conflict. Despite those concerns, S&P 500 futures rose following the reports about NVIDIA’s CEO joining the U.S. delegation, which in turn supported sentiment in chip-related stocks across the region.
China’s Shanghai Shenzhen CSI 300 and the Shanghai Composite were largely unchanged, as was Hong Kong’s Hang Seng, while investors awaited the start of the U.S. president’s state visit to China later in the day. The summit is expected to cover a wide range of issues, including trade tariffs, Taiwan, and artificial intelligence - topics whose outcomes will be watched closely by global markets.
Japan’s equity markets showed constructive moves, with the Nikkei 225 rising 0.7% and the TOPIX advancing 1.2%, helped by gains in domestic technology stocks. Supportive data showed Japan’s current account surplus surged to a record high in March, a development that market commentary attributed to stronger AI-driven demand and a weaker yen bolstering export-related receipts.
Australia and other markets
Australia’s S&P/ASX 200 fell 0.4%, pressured by a roughly 10% drop in Commonwealth Bank Of Australia (ASX:CBA) after the country’s largest lender set aside significantly higher provisions to cover risks linked to the Middle East. The weakness in CBA spilled over to the other major Australian banks, amplifying the losses for the sector and weighing on the broader market.
Meanwhile, Singapore’s Straits Times index rose about 0.8%, and India’s Nifty 50 was essentially flat following steep losses earlier in the week. The mixed performance across markets reflected investor caution as geopolitical and policy risks remained front of mind ahead of the diplomatic engagement between the U.S. and China.
Market implications
Investor focus remains split between geopolitical developments - notably the Iran conflict and its potential inflationary effects - and the diplomatic agenda to be addressed during the U.S.-China summit. Semiconductor stocks have moved to the fore in South Korea on reports linking potential commercial or diplomatic engagement to greater chip demand, while bank stocks in Australia reacted to heightened provisioning tied to Middle East exposures.
As markets digest incoming data and official statements, volatility may persist, particularly in sectors sensitive to trade, geopolitics, and commodity-driven inflationary pressures.
