SK Hynix -2%, Samsung -2.7%, Hyundai -5.5%. Sidecar triggered. MSCI DM exclusion cited. Kospi still up 78-83% YTD despite today&#8217;s fall.<\/em><\/p>\n<p>The Kospi crash on June 23, 2026 has pushed South Korea&#8217;s benchmark index down 5.69% to 8,596 points, as three catalysts hit simultaneously: the MSCI Developed Markets index review excluded South Korea, overnight US technology stocks fell sharply, and leveraged AI-related positions continued unwinding. The Kospi crash triggered a sidecar trading curb on the Korea Exchange as KOSPI 200 futures sank, temporarily halting programme trading. SK Hynix fell 2.0%, Samsung Electronics dropped 2.7%, and Hyundai Motor tumbled 5.5%, with Kia Corporation down 4.2% and HD Hyundai Heavy Industries off 2.2%, showing the Kospi crash extended well beyond semiconductors.<\/p>\n<p>Despite today&#8217;s Kospi crash, the index remains up approximately 78-83% year-to-date in 2026, making it one of the world&#8217;s best-performing major equity benchmarks. Kunal Singla, Associate Director at Univest notes that the Kospi crash is a structural deleveraging episode: foreign investors who bought Korean equities aggressively on the AI semiconductor cycle are now unwinding positions, and the MSCI DM exclusion removes a key anticipated catalyst for further buying that had been priced into valuations.<\/p>\n<p style=\"margin-top: 24px;\"><a href=\"https:\/\/univest.in\/user\/log-in?utm_source=blogs&amp;utm_medium=south-korea-kospi-crash-june-23-2026\"><strong>Click Here &#8211; Get Free Investment Predictions<\/strong><\/a><\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_65 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title \" >Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/univest.in\/blogs-2\/south-korea-kospi-crash-june-23-2026\/#Kospi_Crash_June_23_Trigger_Summary\" title=\"Kospi Crash June 23: Trigger Summary\">Kospi Crash June 23: Trigger Summary<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/univest.in\/blogs-2\/south-korea-kospi-crash-june-23-2026\/#What_Todays_South_Korea_Market_Fall_Means_for_India\" title=\"What Today&#8217;s South Korea Market Fall Means for India\">What Today&#8217;s South Korea Market Fall Means for India<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/univest.in\/blogs-2\/south-korea-kospi-crash-june-23-2026\/#1_IT_Stocks_The_Indian_Parallel\" title=\"1.

South Korea&#8217;s inclusion in MSCI DM had been anticipated as a trigger for billions of dollars of passive fund inflows from index-tracking ETFs and pension funds globally. The exclusion in the upcoming review means this catalyst is deferred, forcing investors who had bought Korean equities specifically in anticipation of DM inclusion to reassess their positions, amplifying the selling pressure of the Kospi crash.<\/p>\n<p>Today&#8217;s Kospi crash is the third significant decline this year following the June 5 crash (-6%, triggered by Broadcom&#8217;s AI chip guidance miss) and the June 8 crash (-8.29%, the worst single-day fall this year). This pattern confirms South Korea&#8217;s equity market, while fundamentally strong on AI semiconductor demand, carries elevated volatility risk due to high leverage and concentrated foreign ownership in a handful of semiconductor names.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Todays_South_Korea_Market_Fall_Means_for_India\"><\/span><strong>What Today&#8217;s South Korea Market Fall Means for India<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"margin-top: 24px;\"><a href=\"https:\/\/univest.in\/screeners\"><strong>Track Global Markets and Indian Equities on Univest Screener<\/strong><\/a><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_IT_Stocks_The_Indian_Parallel\"><\/span><strong>1.
