Asia-Pacific Stocks Slip as Wall Street Rout and Rising Bond Yields Pressure Tech Sector

Equity markets across the Asia-Pacific region retreated on Wednesday, mirroring losses on Wall Street as investors grew more cautious about lofty valuations in the artificial intelligence space and responded to higher government bond yields.

Japan’s Nikkei 225 edged 0.2% lower in choppy trade, while the broader Topix finished almost unchanged. The pullback followed a sharp early slide led by semiconductor equipment maker Advantest, which was down more than 4% at one point before trimming the decline to 0.88%. Chip designer Renesas Electronics fell 4.4%, extending a regional sell-off in technology names.

Japanese government bond yields reached multi-decade highs, adding to the cautious mood. The yield on the 10-year note rose about two basis points to 1.759%, the highest level since 2007. Twenty-year yields climbed nearly three basis points to 2.811%, the strongest reading since 1999, and 30-year yields advanced almost four basis points to 3.334%, hovering near record territory. Rising yields can dilute the appeal of growth stocks by increasing discount rates used in valuation models, a dynamic that weighed on the Nikkei’s heavyweight tech constituents.

In South Korea, the Kospi lost 0.54%, while the small-cap Kosdaq slipped 0.58%. Index bellwethers Samsung Electronics and memory maker SK Hynix softened 0.51% and 0.79%, respectively, after partially recovering steeper early losses. Investors continued to reassess demand projections for AI-related chips following a string of profit-taking sessions in New York.

Australia’s S&P/ASX 200 eased 0.13% in volatile turnover, pressured by weakness in local technology and materials names. In Hong Kong, the Hang Seng Index shed 0.45%, while mainland China’s CSI 300 rose 0.21% as domestic investors rotated into financials and consumer staples.

Hong Kong-listed shares of Chinese device maker Xiaomi tumbled more than 4%. The company cautioned on Tuesday that smartphone prices could increase in 2026 because of higher memory-chip costs driven by surging AI demand. The warning deepened concerns that supply-chain pressures could erode margins for handset producers.

Indian markets also opened weaker. The benchmark Nifty 50 slipped 0.16%, and the Sensex declined 0.14% as traders digested the global pullback in risk assets.

Overnight in the United States, major indexes extended their recent declines. The Dow Jones Industrial Average fell 498.50 points, or 1.07%, to 46,091.74, registering a fourth straight down day. The broad-based S&P 500 dropped 0.83% to 6,617.32, also marking a four-session losing streak—the index’s longest slide since August. The tech-heavy Nasdaq Composite slid 1.21% to 22,432.85, its fifth negative finish in six sessions.

U.S. equity futures were little changed during Asian trading hours, offering few cues for regional investors. Nonetheless, sentiment remained fragile after higher global bond yields signaled expectations that central banks may keep policy tighter for longer to combat inflation.

Cryptocurrency markets echoed the risk-off tone. Bitcoin briefly dipped below the $90,000 mark before stabilizing, reflecting reduced appetite for speculative assets amid the broader market pullback.

Market participants cited two key drivers behind Wednesday’s synchronized declines. First, a growing debate over whether AI-linked stocks can sustain current valuations has prompted profit-taking in semiconductor and hardware names across geographies. Second, the uptrend in longer-dated bond yields, particularly in Japan, is lifting discount rates applied to future earnings, lowering present-value calculations for high-growth companies.

Despite the day’s weakness, some analysts noted that regional benchmarks remain near multi-year highs, suggesting investors are rotating rather than exiting equity exposure outright. Upcoming U.S. inflation data and corporate earnings are expected to provide further direction.

Trading volumes across Asia were moderate as several markets approach fiscal year-end reporting periods. No major economic releases were scheduled in the region for the day, leaving global macro moves as the primary catalyst for price action.
