Fears of a Chinese memory-chip price offensive triggered a synchronized Asian sell-off on July 28. Korea's KOSPI fell over 8%, tripping its eighth circuit breaker of the year; Taiwan's TSMC saw about T$2 trillion in value briefly wiped out; Japan halted trading as the Nikkei plunged over 2,500 points. Chinese investors and firms feel the shock too.
The KOSPI plunged more than 8% from the prior session on July 28, tripping the circuit breaker that pauses trading on sharp moves, Kyunghyang and Chosun reported. It was the eighth trip this year; a sell-side sidecar in the morning gave way to a deeper afternoon slide and a halt.
광고 문의 · 300×250The trigger was fear of a low-price supply offensive by Chinese memory makers. Samsung Electronics and SK Hynix both fell 7-10%, and semiconductor and storage names weakened together, dragging the index down.
Taiwan's market also tumbled. The Liberty Times reported TSMC fell sharply intraday, briefly erasing more than T$2 trillion in market value. Chip heavyweight Yageo hit its daily limit-down, and the weighted index lost nearly 7%.
Selling spreads across Asia
The United Daily News said Korean shares fell over 7% to trip a halt, the Nikkei crashed more than 2,500 points, and Japan's memory maker Kioxia plunged 18%. This was not one company's bad news but a broad loss of confidence in the chip supply chain, hence the depth of the fall.
In the U.S. the prior day, Nvidia fell 5% and ceded the top market-cap spot to Apple, while questions over circular financing around OpenAI sharpened risk aversion.
What pulled the trigger
The immediate catalyst was concern that Chinese memory expansion and low pricing could again push down global DRAM and NAND prices. Foreign selling plus forced liquidation and rebalancing by leveraged ETFs amplified the drop, many analysts said.
Some urge caution, however: excessive nerves ahead of a 'super week' of earnings and central-bank decisions, not a sudden shift in fundamentals.
What it means for Chinese economies
Sharp currency and equity swings are a direct variable for Chinese self-employed and students rooted in Korea and for traders dealing with Taiwan and China. A weaker won compounds import costs and remittance burdens. Sinophone Bridge Times recommends no forecast; the judgment rests with individuals and firms.
A third lens
We do not reduce this rout to 'China's fault.' Expanding memory supply is the product of industrial policy, demand cycles and monetary conditions across many countries at once. We place the Korean, Taiwanese, Japanese and U.S. views side by side so readers can separate panic from fact.
