Yonhap News<\/p>\n<p class=\"mb-4 text-[var(--color-text)] leading-relaxed\">Samsung Electronics (005930.KS) and SK hynix (000660.KS) tumbled in premarket trading as fears over Middle East instability, driven by the U.S.-Iran conflict, and a surge in bond yields rattled market sentiment.<\/p>\n<p class=\"mb-4 text-[var(--color-text)] leading-relaxed\">According to Nextrade on the 19th, Samsung Electronics traded at 256,500 won, down 12,000 won, or 4.47%, from the previous session during premarket hours from 8 a.m. to 8:50 a.m. SK hynix fell 98,000 won, or 5.90%, to 1.564 million won. Other large-cap stocks also weakened across the board, including SK Square (-7.31%), Samsung Electro-Mechanics (-6.39%), Hyundai Motor (-3.56%) and LG Energy Solution (-1.99%).<\/p>\n<p class=\"mb-4 text-[var(--color-text)] leading-relaxed\">The sharp declines were attributed to Middle East tensions and the spike in bond yields. A failure to extend a U.S.-Iran ceasefire heightened geopolitical risks in the region. As oil prices climbed and inflationary pressure came into focus, a selloff in U.S. Treasurys pushed yields higher. The jump in bond yields sharply dampened appetite for risk assets, weighing on the market.<\/p>\n<p class=\"mb-4 text-[var(--color-text)] leading-relaxed\">The U.S. 30-year Treasury yield climbed as high as 5.33% during the session, its highest level in 19 years since 2007. The U.S. 10-year Treasury yield, a benchmark for global market rates, hovered near 4.71%, close to its highest level since January 2005. International oil prices rose for a third straight day. Brent crude for October delivery and U.S. West Texas Intermediate (WTI) futures for September delivery settled at $91.02 and $84.95 a barrel, up 0.17% and 0.52% from the prior session, respectively.<\/p>\n<p class=\"mb-4 text-[var(--color-text)] leading-relaxed\">On Wall Street, chip stocks fell sharply under pressure from profit-taking and high interest rates. Micron Technology (-7.06%), SanDisk (-8.89%) and Western Digital (-7.43%) all posted steep losses. SK hynix&#8217;s American depositary receipts (ADRs) dropped 9.20%, while the Philadelphia Semiconductor Index (SOX) declined 4.98%.<\/p>\n<p class=\"mb-4 text-[var(--color-text)] leading-relaxed\">&#8220;We need to prepare for the possibility that sensitivity to U.S. 10-year and 30-year yields could temporarily increase,&#8221; said Han Ji-young, an analyst at Kiwoom Securities.<\/p>\n","protected":false},"excerpt":{"rendered":"On Aug. 18, the KOSPI and other indices are displayed on a status board at the Hana Bank&hellip;\n","protected":false},"author":2,"featured_media":123973,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[335,14212,28451,276,279,241,275,14369],"class_list":["post-123972","post","type-post","status-publish","format-standard","has-post-thumbnail","category-sk-hynix","tag-kospi","tag-middle-east-tensions","tag-premarket-trading","tag-samsung-electronics","tag-semiconductor-stocks","tag-sk","tag-sk-hynix","tag-u-s-treasury-yields"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/123972","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/comments?post=123972"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/123972\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media\/123973"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media?parent=123972"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/categories?post=123972"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/tags?post=123972"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
