Asian markets slide amid global bond rout, tech stocks tumble

August 19, 2026 (MLN): Asian markets came under pressure on Wednesday, with technology and semiconductor stocks leading losses as rising global bond yields weighed on investor sentiment and prompted a pullback in U.S. technology shares.

South Korea’s Kospi fell 5.54%, while the Kosdaq declined 0.27%. Japan’s Nikkei 225 dropped 2.64% and the Topix lost 2.76%.

Australia’s S&P/ASX 200 slipped 0.39%, while Hong Kong’s Hang Seng Index edged 0.2% higher. Mainland China’s CSI 300 declined 2.41%, according to CNBC.

Technology stocks recorded sharper declines. In Japan, SoftBank Group dropped 5.44%, Tokyo Electron fell 3.85%, Advantest declined 3.93%, while memory chipmaker Kioxia plunged 9.13%.

In South Korea, SK Hynix tumbled 8.66%, Samsung Electronics declined 7.08%, and Seoul Semiconductor fell 4.33%. Semiconductor stocks have remained highly volatile in recent sessions, with South Korea’s technology-heavy market swinging between steep losses and record gains.

The sell-off followed another weak session on Wall Street, where the major U.S. indexes declined for a third consecutive day amid a global bond-market sell-off and higher oil prices.

The Dow Jones Industrial Average fell 116 points, or 0.2%, while the S&P 500 declined 0.7%. The Nasdaq Composite dropped 1.3%, recording the largest decline among the three major indexes.

U.S. stock futures were little changed early Wednesday. Dow futures gained 46 points, while S&P 500 futures slipped 0.1% and Nasdaq 100 futures declined 0.2%.

Rising bond yields remained a key concern for investors. The U.S. 30-year Treasury yield reached a new 19-year high on Tuesday, while Japan’s 10-year government bond yield climbed to its highest level in three decades.

Germany’s 30-year bond yield reached its highest level since 2011, while France’s 30-year borrowing costs rose to their highest level since 2008.

Despite the sharp rise in long-term borrowing costs, the broader stock-market reaction remained relatively contained, with investors expecting continued economic growth and strong corporate earnings to provide support for equities.

Markets are also awaiting the minutes of the Federal Open Market Committee’s latest meeting, due later Wednesday. Investors are expected to focus on the divisions within the U.S. Federal Reserve after three policymakers dissented in favor of a rate increase at the July meeting.

The earnings calendar also remains busy, with Target, TJX and Lowe’s scheduled to report before the U.S. market opens, while Analog Devices is also due to release results.
