It seems that fears of an AI and technology bubble are once again unsettling global markets. A massive sell-off in AI and tech stocks on June 26 rattled Asian equities, triggering a domino effect across major indices. South Korea’s KOSPI led the decline, slipping 8%. This was followed by sharp weakness in Taiwan’s weighted index, while Japan’s Nikkei fell around 5%. The selling pressure spread quickly across the region. So, what factors are driving this bloodbath in global stock markets? Let’s take a closer look and conduct a deeper analysis.

What has happened in Asian Markets Today?

The June 16 have proved fatal for the Asian markets. The bloodshed which was triggered by the South Korean index KOSPI rattled the complete Asian indices.

Taiwan’s TAIEX dropped 3.3% under pressure from heavy selling in hardware and chip stocks.

Why is Asian Share Market Falling Today?

Which factors triggered the decline?

The sharp reversal in the tech sector was first triggered by sudden corporate changes in the US. Apple shares fell more than 6% overnight after the company raised prices on its iPad and Mac product lines. The company said it could no longer absorb the fast-rising cost of memory and storage chips, which have surged due to global data center expansion. This move sent a strong signal to markets. It showed that rising input costs are starting to squeeze corporate profits. It also raised concerns that higher prices could eventually reduce consumer demand, adding further pressure on the tech sector.

What’s the reason behind KOSPI’s sharp decline?

As the KOSPI is heavily weighted toward consumer technology and hardware, it became the main center of today’s market crash. The sharp fall forced regulators to trigger circuit breakers and temporarily pause trading as selling pressure intensified. Semiconductor giants Samsung Electronics and SK Hynix came under heavy pressure, as they account for over 50% of the South Korean index’s valuation. While domestic retail investors tried to support the market with strong dip buying and record inflows, their efforts were not enough to offset the scale of institutional outflows from export-focused Asian equities.

Has AI bubble burst?

The main reason behind today’s sharp sell-off is growing concern over stretched valuations and heavy profit booking by institutional investors. After pouring trillions into AI-linked companies and pushing Asian markets to record highs earlier this week, global funds have started stepping back to reassess the rally. Investors are now realizing that even though companies are spending heavily on building AI data centers, short-term revenue and profit growth are not keeping pace. This gap between spending and earnings has made current stock prices hard to justify, leading to a broad technical correction across markets.

Japan’s economic data also adding pressure

The tech sell-off was also deepened by broader economic pressures. In Tokyo, new data showed core inflation rising to 1.6%. This signals that price pressures in the region are still building, which may keep interest rates higher for longer. At the same time, market sentiment turned cautious after reports of a strike on a commercial cargo ship near the Strait of Hormuz. The incident raised fears of disrupted shipping routes, higher fuel costs, and added stress on global supply chains.

Federal Reserve’s rate hike indication made situation worst

At the June 17 FOMC meeting, newly appointed Fed Chair Kevin Warsh kept benchmark interest rates unchanged at 3.5% to 3.75%. However, nearly half of the policymakers, 9 out of 19, signaled they now expect at least one rate hike before the end of the year. Following this, major Wall Street firms like Bank of America revised their outlook and warned that the Fed could even deliver up to three rate hikes if inflation remains sticky. This tighter policy outlook has also increased pressure on global markets. As US bond yields rise, global investors are moving money out of Asian equities and into safer dollar assets that now offer better returns.
