Asian equity markets experienced significant turbulence on Tuesday as concerns about China’s advancing semiconductor capabilities sent shockwaves through the technology sector.
The benchmark Kospi index plunged 10.8% to settle at 6,023.66, representing its lowest close in months. Circuit breakers were triggered several times throughout the trading session as the rapid descent prompted automatic trading pauses.
Major Chip Manufacturers Face Severe Declines
Samsung Electronics suffered a 13.4% decline while SK Hynix experienced a devastating 14.7% drop. The latter had recently completed its Wall Street listing, with shares priced at $149 during the initial public offering. By Monday’s close, the U.S.-traded securities had already slipped to $143, trading beneath their debut price.
The catalyst for this dramatic selloff emerged from a detailed report published by technology news outlet The Information. The article revealed that China had commenced large-scale manufacturing of domestically engineered deep ultraviolet (DUV) lithography systems — critical machinery utilized for etching intricate circuit designs onto semiconductor wafers.
This development intensified concerns that Chinese semiconductor producers might narrow the technological divide with international industry leaders more rapidly than market participants had anticipated.
Compounding investor anxiety, CXMT, a Chinese memory chip producer, launched its Shanghai stock exchange listing on Monday with an extraordinary 466% price explosion. The enterprise secured a minimum of $8.6 billion through its public offering. However, the stock retreated 4% during Tuesday’s session.
Research analysts from Morningstar observed that markets were clearly “spooked” by indications of China’s semiconductor manufacturing advancement. Equity analyst Jing Jie Yu characterized the selling wave as “largely a knee-jerk reaction and overdone,” emphasizing that the commanding market position held by established global chip manufacturers remains unlikely to face substantial challenges.
Regional Markets Experience Widespread Declines
The wave of selling extended throughout Asian trading floors. Japan’s Nikkei 225 index tumbled 4% to 62,364.92. Taiwan’s Taiex index registered a 4.7% loss, with TSMC shares sliding 3%.
Hong Kong’s Hang Seng index defied the prevailing sentiment, advancing 0.3%. Shanghai’s Composite index declined 1.2%.
Across the Pacific in the United States, semiconductor equities had encountered headwinds during Monday’s trading. Nvidia retreated 5%, Advanced Micro Devices declined 5.2%, and Micron Technology shed 2.3%.
Energy markets also came under pressure, with oil prices declining more than 2% as diplomatic tensions between the United States and Iran appeared to moderate. Brent crude slipped to $84.07 per barrel, while the U.S. benchmark crude dropped to $80.99.
The S&P 500 finished Monday’s session essentially unchanged while the Dow Jones Industrial Average managed a 0.5% gain. The Nasdaq edged 0.2% into negative territory.
Market participants indicated that portions of the selling activity represent investors locking in gains following an extended rally in artificial intelligence-focused equities. Questions surrounding whether the AI sector’s momentum can validate current price levels have been intensifying for several months.
Tuesday’s severe decline in the Kospi represents one of the most substantial single-session percentage losses recorded by the index in recent memory.
