Baghaei emphasized that <strong>diplomacy takes time<\/strong> and that current negotiations are focused on ending the war rather than the specific details of the nuclear file or highly enriched uranium.<\/p>\n<p>Despite the diplomatic deadlock, Iranian state media reported that <strong>35 vessels transited the Strait of Hormuz<\/strong> over the last 24 hours in coordination with Iranian naval forces. Secretary of State <strong>Marco Rubio<\/strong> condemned Iran\u2019s efforts to institutionalize a &quot;tolling system&quot; for the waterway, asserting that the U.S. will not tolerate Tehran&#39;s attempt to monetize access to a vital global energy artery.<\/p>\n<p>In the technology sector, Micron Technology (<a href=\"\/stock\/MU\">MU<\/a>) shares were in focus after CEO Sanjay Mehrotra projected that <strong>DRAM and NAND flash memory shortages<\/strong> will last at least until 2027. Mehrotra noted that the company can currently only meet <strong>half to two-thirds of demand<\/strong> from its key customers as AI-driven requirements continue to outstrip global supply capacity.<\/p>\n<p>Addressing trade concerns, <strong>USTR Jamieson Greer<\/strong> clarified that there are no imminent plans to impose new tariffs on semiconductor imports. However, Greer maintained that trade barriers remain a critical tool for <strong>facilitating the reshoring of chip production<\/strong> and protecting the billions of dollars currently being invested in U.S.-based manufacturing facilities.<\/p>\n<p>In domestic politics, President Trump announced that <strong>Tulsi Gabbard<\/strong> will leave the administration on June 30, citing personal family health reasons. <strong>Aaron Lukas<\/strong>, the current Principal Deputy Director of National Intelligence, has been appointed to serve as the <strong>Acting Intelligence Director<\/strong> following her departure.<\/p>\n<p>Meanwhile, in Europe, the Italian government has officially approved an extension of <strong>fuel tax cuts<\/strong> to help households and businesses manage high energy costs. The measure, which was set to expire, was prolonged as Italy remains particularly vulnerable to energy supply disruptions linked to the ongoing <strong>Middle East conflict<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Iran\u2019s Foreign Ministry has cooled expectations of an &quot;imminent&quot;
