The <strong>Nasdaq<\/strong> fell an additional <strong>2.00%<\/strong> in afternoon trading, reflecting a broader retreat from risk assets as investors grapple with the economic fallout of &quot;Operation Epic Fury.&quot;<\/p>\n<p><em>Energy markets are reacting sharply to the escalating violence<\/em>, with <strong>US oil prices surpassing $100 per barrel<\/strong> before settlement. Analysts warn that sustained triple-digit oil prices could <em>severely hamper global growth and reignite inflationary pressures<\/em> that central banks have struggled to contain.<\/p>\n<h2>Nuclear and Industrial Sites Targeted<\/h2>\n<p>The International Atomic Energy Agency (IAEA) confirmed today that it was informed by Iran of an attack on the <strong>Shahid Rezayee Nejad yellow cake production facility<\/strong> in Yazd province. While the IAEA is currently looking into the report, it noted that <strong>no increase in off-site radiation levels<\/strong> has been detected thus far.<\/p>\n<p>Iran\u2019s Foreign Minister, Abbas Araghchi, claimed that <strong>Israel targeted two of Iran&#39;s largest steel factories<\/strong>, a power plant, and various nuclear sites. Araghchi alleged these strikes were coordinated with the U.S. and violated previous diplomatic deadlines. Meanwhile, <strong>Houthi military forces in Yemen<\/strong> announced that a formal statement is forthcoming, raising fears of a wider regional escalation.<\/p>\n<h2>Corporate Credit Risk and Tech Developments<\/h2>\n<p>In the corporate sector, the cost to insure against a default by <strong>Oracle (<a href=\"\/stock\/ORCL\">ORCL<\/a>)<\/strong> has surged. <strong>Oracle&#39;s credit default swaps<\/strong> are now approaching their <strong>2008 financial crisis highs<\/strong>, as the market grows increasingly wary of the company&#39;s <strong>$100 billion-plus debt load<\/strong> and aggressive spending on AI infrastructure.<\/p>\n<p>Conversely, <strong>Google (<a href=\"\/stock\/GOOGL\">GOOGL<\/a>)<\/strong> is reportedly moving forward with a deal to help finance a <strong>multi-billion dollar data center<\/strong> for Anthropic.

enforcement measures.<\/p>\n<p>Amidst the geopolitical tension, <strong>NASA&#39;s Moon mission team<\/strong> has reached the Kennedy Space Center, marking a rare moment of scientific progress during
