Cory Mills in Florida\u2019s 7th Congressional District GOP primary, amid ongoing ethics investigations into the incumbent.<\/li>\n<\/ul>\n<h2>Market Volatility Driven by Yield Spikes and Geopolitics<\/h2>\n<p>Investors turned defensive on Wednesday as a &quot;risk-off&quot; sentiment permeated global markets, fueled by a combination of <strong>persistent inflation<\/strong>, <strong>rising government debt<\/strong>, and <strong>geopolitical instability<\/strong>. The <strong>U.S. 30-year Treasury yield<\/strong> briefly touched <strong>5.34%<\/strong>, a level not seen in nearly two decades, while the <strong>10-year yield hit 4.75%<\/strong>. This surge in long-term yields has raised significant alarms regarding the sustainability of expensive <strong>AI infrastructure spending<\/strong> and broader corporate borrowing costs.<\/p>\n<p>In the Middle East, the <strong>Strait of Hormuz<\/strong> remains a critical flashpoint. <strong>Brent crude<\/strong> traded above <strong>$91<\/strong>, and <strong><a href=\"https:\/\/stockmarketwatch.com\/metal\/gold\" data-internallinksmanager029f6b8e52c=\"4\" title=\"gold price today\">Gold<\/a><\/strong> held near <strong>$4,340<\/strong> as markets awaited the Federal Reserve&#39;s latest meeting minutes for policy clues. Ebrahim Azizi, chairman of Iran\u2019s National Security and Foreign Policy Committee, warned France against a &quot;hostile&quot; approach, further complicating diplomatic efforts to reopen the waterway, which typically handles a fifth of global oil consumption.<\/p>\n<h2>Tech Selloff Hits Asian Markets<\/h2>\n<p>The global semiconductor rout deepened in Asian trading, with the <strong>MSCI Asia Pacific Index<\/strong> dropping more than <strong>1%<\/strong>. South Korean markets bore the brunt of the selloff; Samsung Electronics (<a href=\"\/stock\/SSNLF\">SSNLF<\/a>) and SK Hynix (<a href=\"\/stock\/HYMTF\">HYMTF<\/a>) saw their shares tumble roughly <strong>7%<\/strong> and <strong>8%<\/strong>, respectively. This followed a <strong>5% decline<\/strong> in the Philadelphia Semiconductor Index, as investors reassessed the valuation of chipmakers amid higher interest rates and cooling demand for non-AI electronics.<\/p>\n<h2>Strategic Industrial and Defense Developments<\/h2>\n<p>Despite the broader market gloom, <strong>LG Energy Solution<\/strong> marked a milestone with the start of production at its <strong>Lansing, Michigan<\/strong> facility. The plant will produce <strong>nickel-manganese-cobalt (NMC)<\/strong> cells for Toyota (<a href=\"\/stock\/TM\">TM<\/a>)&#39;s 2027 Highlander EV and <strong>lithium-iron-phosphate (LFP)<\/strong> cells for Tesla (<a href=\"\/stock\/TSLA\">TSLA<\/a>)&#39;s Megapack 3 energy storage systems. The facility is expected to reach an annual capacity of <strong>35GWh<\/strong>, supporting U.S. domestic content requirements under current trade policies.<\/p>\n<p>Concurrently, the <strong>U.S. Army<\/strong> is accelerating its defense posture in the Pacific, preparing to activate a new <strong>Patriot air-defense battalion<\/strong> on <strong>Guam<\/strong> this October. The <strong>3rd Battalion, 43rd Air Defense Artillery Regiment<\/strong> will provide 360-degree protection against ballistic and hypersonic threats. However, defense analysts note that <strong>Patriot interceptor stocks<\/strong> remain strained due to ongoing consumption in Middle Eastern conflicts and transfers to Ukraine, pressuring primary contractors like Raytheon (RTX (<a href=\"\/stock\/RTX\">RTX<\/a>)) and Lockheed Martin (<a href=\"\/stock\/LMT\">LMT<\/a>).<\/p>\n<h2>Political Upset in Florida<\/h2>\n<p>In domestic politics, <strong>CNN\u2019s Decision Desk<\/strong> projects that <strong>Ryan Elijah<\/strong> will win the GOP primary for <strong>Florida&#39;s 7th Congressional District<\/strong>. Elijah, a former news anchor, successfully unseated incumbent <strong>Rep. Cory Mills<\/strong>, who had received the endorsement of Donald Trump. The race was overshadowed by a <strong>House Ethics Committee investigation<\/strong> into Mills regarding alleged violations of campaign finance laws and misconduct, signaling a potential shift in voter sentiment within the district ahead of the general election.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Global equities and futures fell sharply as the U.S. 30-year
