Asian stocks steady as tech slump fuels fresh volatility

Asian stocks were mixed on June 24 as a tech-led global selloff, a weak yen and lower oil prices kept investors wary of renewed volatility.

Trading was uneven across the region after a sharp retreat in technology and semiconductor names the previous day. Analysts said the speed of recent market swings, in both directions, is heightening concerns about market stability.

Asia opens uneven after tech and chip selloff

MSCI’s broad Asia-Pacific index excluding Japan was little changed, down 0.02%. Japan’s Nikkei moved between gains and losses before last trading down 0.8%.

South Korea’s benchmark rebounded 2.2% a day after plunging 10%, its steepest one-day fall since March. The reversal underscored how quickly risk appetite has been rotating after the global pullback in high-growth sectors.

Michael McCarthy, a market analyst at Moomoo Securities Australia, said the past seven sessions showed “alarming” price action. He argued that rapid moves—whether up or down—often signal instability rather than conviction.

Wall Street slides as AI spending and Fed stance debated

Overnight, a broad risk-off tone hit U.S. markets, following weakness seen earlier across Europe and parts of Asia. Investors focused on concerns that debt-funded spending tied to artificial intelligence could be rising, while also weighing the possibility of a more hawkish Federal Reserve.

U.S. equities closed lower, led by technology-heavy benchmarks. The Dow Jones Industrial Average slipped 0.09%, the S&P 500 fell 1.4%, and the Nasdaq Composite dropped 2.2%.

At the same time, demand for safety lifted government bonds, pushing yields down. The benchmark 10-year U.S. Treasury yield fell 1.41 basis points to 4.493%.

Oil falls near four-month lows; yen hovers near 40-year weak

Oil prices extended losses and hovered near four-month lows reached in the prior session. The slide followed signs that more tankers delayed in the Gulf since the start of the Iran war may be able to move out through the Strait of Hormuz.

Even so, markets continued to price in geopolitical uncertainty. The United States and Iran have offered differing descriptions of what was agreed under a peace arrangement, including key issues such as nuclear inspections and how control of the Strait of Hormuz would be handled.

In currency markets, the dollar’s strength kept pressure on the Japanese yen, which traded near a roughly 40-year low at 161.57 per dollar. The level has sustained investor attention on the risk of Japanese authorities stepping in to support the currency.

Adding to focus on Japan, a summary of opinions from the Bank of Japan’s meeting this month was released on Wednesday. The BOJ had lifted interest rates to 1.00%, a 31-year high, and the summary showed some board members supported additional increases to bring policy closer to a neutral setting.

For investors, the cross-currents—tech-sector repricing, shifting expectations for central banks, energy-market headlines, and currency pressure in Japan—are reinforcing a short-term volatility backdrop. The next tests will be whether U.S. yields continue to fall on risk aversion, and whether yen weakness prompts clearer signals from policymakers or intervention watch to intensify.
