The index opened sharply lower and plummeted as much as <strong>8.8%<\/strong> within minutes, forcing the <strong>Korea Exchange<\/strong> to activate a Level 1 circuit breaker at 9:03 a.m. local time. This marked the 11th time in 2026 that trading was halted due to excessive volatility, driven primarily by a fierce exodus of foreign capital from heavyweight technology and semiconductor stocks.<\/p>\n<p>In an immediate response to the rout, Finance Minister <strong>Lee Hyoung-il<\/strong> pledged a &quot;proactive and bold&quot; response to stabilize investor sentiment. The government announced that starting November 9, it will temporarily ease restrictions on <strong>borrowed investment<\/strong> for a period of three months. Specifically, securities firms will be exempt from the mandatory <strong>140% collateral maintenance ratio<\/strong>, a move designed to curb the &quot;vicious cycle&quot; of forced liquidations that has intensified the downward pressure on stock prices.<\/p>\n<h2>AI Sector Reels from U.S. Election Fallout<\/h2>\n<p>The catalyst for the Asian market collapse was a brutal overnight session on Wall Street, where the <strong>Nasdaq Composite<\/strong> fell <strong>5.52%<\/strong> and the <strong>Philadelphia Semiconductor Index<\/strong> cratered <strong>12.25%<\/strong>. Investors reacted to the results of the U.S. midterm elections, which saw the Democratic Party gain control of both chambers of Congress. Markets are pricing in a &quot;Blue Wave&quot; regulatory environment that could include stricter oversight of <strong>AI infrastructure<\/strong>, data center construction, and potential pauses in federal support for tech expansion.<\/p>\n<p>South Korean chip giants bore the brunt of the regional spillover. Samsung Electronics (<a href=\"\/stock\/005930\">005930<\/a>) fell nearly <strong>10%<\/strong>, while SK Hynix (<a href=\"\/stock\/000660\">000660<\/a>) plunged over <strong>11.7%<\/strong> despite recently reporting record quarterly sales. Finance Minister Lee noted that while the market is &quot;overreacting to external factors,&quot; the government remains on high vigilance, with the <strong>Bank of Korea<\/strong> also moving to manage liquidity by selling 91-day stabilization bonds at a yield of <strong>3.175%<\/strong>.<\/p>\n<h2>China and Netherlands Address Supply Chain Security<\/h2>\n<p>Amid the broader market turmoil, <strong>China<\/strong> and the <strong>Netherlands<\/strong> concluded the ninth meeting of their <strong>Export Control Dialogue Mechanism<\/strong> in Shenzhen on November 5. Officials from the Chinese Ministry of Commerce and the Dutch Ministry of Foreign Affairs discussed sensitive issues regarding the <strong>semiconductor sector<\/strong> and dual-use technologies. Both nations agreed to maintain close communication to ensure the &quot;stability and smooth operation&quot; of global industrial supply chains, signaling a continued effort to manage bilateral trade frictions despite broader geopolitical shifts.<\/p>\n<p>Simultaneously, <strong>Xinhua<\/strong> reported that China\u2019s top legislature has officially adopted a new law focused on <strong>cross-border anti-corruption<\/strong>. The legislation, which contains 47 articles, is aimed at deepening international cooperation and protecting China&#39;s sovereignty and development interests. It requires Chinese companies operating internationally to establish dedicated integrity and compliance departments, reflecting Beijing&#39;s push for a more systematic legal framework for its global economic activities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways South Korea\u2019s KOSPI index plunged 8.5% to 4,924.61, falling below the critical 5,000-point threshold for
