South Korea\u2019s <strong>KOSPI<\/strong> plummeted <strong>9.99%<\/strong> to 8,203.84, driven by aggressive selling in semiconductor giants like Samsung (<a href=\"\/stock\/005930\">005930<\/a>) and SK Hynix (<a href=\"\/stock\/000660\">000660<\/a>). This &quot;hard selling shock&quot; reflects growing fears that the concentration in AI memory demand has left the broader market vulnerable to rate hikes and tech sector exhaustion.<\/p>\n<p>In the private markets, SpaceX shares fell <strong>4.9% to $147<\/strong>, sliding below its first-day opening price. The broader sell-off in Big Tech is being exacerbated by a strengthening US Dollar, with the <strong>US Dollar Index rising 0.1% to 101.13<\/strong>, its highest point in over a year. Consequently, precious metals are bleeding value; <strong>Spot Silver<\/strong> dropped nearly <strong>5% to $61.89\/oz<\/strong>, while <strong>Spot Gold<\/strong> fell <strong>2% to $4,108.37\/oz<\/strong>.<\/p>\n<h2>Eurozone Economic Divergence<\/h2>\n<p>The Eurozone&#39;s economic recovery appears uneven as June PMI data shows a mix of slight improvement and localized contraction. The <strong>Eurozone Composite PMI rose to 49.5<\/strong>, beating estimates of 49.2, but remains below the 50-point threshold that separates growth from contraction. While services showed resilience at <strong>48.9<\/strong>, manufacturing missed expectations at <strong>51.3<\/strong>.<\/p>\n<p>The region&#39;s heavyweights are struggling, with <strong>Germany\u2019s Composite PMI falling to 48.0<\/strong> and French business activity shrinking for a sixth consecutive month. High energy costs continue to dampen consumer spending and business confidence across the continent. Adding to the regional pressure, <strong>Spain&#39;s Trade Balance<\/strong> deficit widened to <strong>-5.172B EUR<\/strong> in April, up from -4.372B EUR previously.<\/p>\n<h2>Breakthrough in US-Iran Negotiations<\/h2>\n<p>Diplomatic efforts in Switzerland have yielded &quot;good progress&quot; according to Iranian officials. Iranian Deputy Foreign Minister <strong>Kazem Gharibabadi<\/strong> confirmed that four-way technical talks have concluded with an agreement on mechanisms for future negotiations. These talks involve high-level representation from the US, Iran, Pakistan, and Qatar.<\/p>\n<p>US Vice President <strong>JD Vance<\/strong> noted that Iran has agreed to invite <strong>IAEA inspectors<\/strong> back into the country, a move described as a critical first step toward a broader nuclear settlement. However, the Iranian Foreign Ministry warned that any final understanding must be based on &quot;mutual respect&quot; rather than &quot;arrogant rhetoric.&quot; The <strong>EUR\/USD<\/strong> pair dropped <strong>0.2% to 1.1410<\/strong> on the news, hitting its lowest level since August.<\/p>\n<h2>Energy and Corporate Developments<\/h2>\n<p>US Energy Secretary <strong>Chris Wright<\/strong> and Qatari officials have issued a joint warning via the <em>Financial Times<\/em>, stating that <strong>EU Methane Rules<\/strong> could trigger a global gas supply crunch. They argue the regulations may restrict supply just as the transition away from dirtier fuels requires stable gas flows.<\/p>\n<p>In corporate news, Toyota (<a href=\"\/stock\/TM\">TM<\/a>) announced plans to cut overseas production by <strong>100,000 units<\/strong>, according to <em>Nikkei<\/em>. Conversely, battery giant <strong>CATL<\/strong> expects its production capacity to surpass <strong>1000GWh<\/strong> this year. In the financial services sector, <strong>KPMG<\/strong> faces leadership upheaval as its chair and senior partners prepare to quit following the fallout from a major audit scandal.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Global equity markets are under intense pressure as a massive sell-off in Big Tech and AI-linked stocks triggered
