Vance<\/strong> (<a href=\"\/stock\/VANCE\">VANCE<\/a>) and a high-level U.S. delegation, including <strong>Jared Kushner<\/strong> and <strong>Steve Witkoff<\/strong>, landed in Switzerland early Sunday to begin technical talks with Iranian officials. The <strong>Lake Lucerne Summit<\/strong>, mediated by <strong>Qatar<\/strong> and <strong>Pakistan<\/strong>, aims to transform a fragile interim memorandum into a permanent peace treaty. Vance characterized the meeting as &quot;historic,&quot; noting that such high-level face-to-face engagements between Washington and Tehran have not occurred in decades.<\/p>\n<p>The negotiations are set against a backdrop of renewed violence in <strong>Lebanon<\/strong>, where Israeli strikes against <strong>Hezbollah<\/strong> positions have threatened the stability of the broader U.S.-Iran ceasefire. Vance emphasized that achieving a full regional ceasefire and addressing Iran&#39;s nuclear ambitions are the administration&#39;s top priorities during this 60-day window.<\/p>\n<h2>Trump\u2019s &quot;Guardian Angel&quot; Ultimatum<\/h2>\n<p>In a series of early morning posts on <strong>Truth Social<\/strong>, <strong>President Donald Trump<\/strong> (<a href=\"\/stock\/TRUMP\">TRUMP<\/a>) issued a stark warning to Tehran regarding the <strong>Strait of Hormuz<\/strong>. While confirming there will be <strong>no tolls<\/strong> during the 60-day ceasefire period, Trump asserted that the U.S. may impose passage fees thereafter to reimburse security costs if Iran fails to cooperate. He suggested the U.S. could take up to <strong>20% of the oil<\/strong> passing through the strait as a &quot;guardian angel&quot; fee for maintaining regional stability.<\/p>\n<p>Trump also warned that if Iran attempts to close the strait permanently, &quot;their country will be finished.&quot; He specifically targeted Iranian proxies in Lebanon, demanding an immediate halt to their activities. &quot;If they don\u2019t, we\u2019ll hit Iran very hard again, just like we did last week, only harder!!!&quot; the President wrote, referring to recent military engagements.<\/p>\n<h2>Market Implications and Regional Stability<\/h2>\n<p>The <strong>Strait of Hormuz<\/strong> remains the world&#39;s most critical energy chokepoint, with nearly <strong>20 million barrels of oil per day<\/strong> transiting the waterway. The threat of U.S.-imposed tolls or Iranian closures has kept global energy markets on edge. Analysts suggest that any disruption to the free flow of traffic could see <strong>Brent Crude<\/strong> prices surge well beyond recent peaks, impacting major importers across Asia and Europe.<\/p>\n<p>Despite the rhetoric, <strong>U.S. Central Command (CENTCOM)<\/strong> has pushed back against Iranian claims of control over the strait, stating that commercial traffic continues to flow under U.S. protection. The success of the <strong>Lake Lucerne Summit<\/strong> is now seen as the primary factor in preventing a return to full-scale maritime conflict and ensuring the long-term stability of global energy supply chains.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways President Donald Trump has threatened to impose US-led passage fees in the Strait of Hormuz if a final
