This warning, broadcast on Iranian state TV on Saturday, follows a dramatic reversal in Tehran&#39;s maritime policy. Just one day after declaring the <strong>Strait of Hormuz<\/strong> open to commercial traffic, Iranian authorities have reimposed a total blockade, citing the continued presence of a US naval siege on its own ports.<\/p>\n<p>The local IRGC commander in the <strong>Strait of Hormuz<\/strong> emphasized that the waterway is now a <strong>&quot;combat zone&quot;<\/strong> under the &quot;strict management and control&quot; of the Iranian armed forces. Any vessel that ignores radio warnings or attempts to pass without obtaining specific Iranian permits will be <strong>targeted and &quot;hit,&quot;<\/strong> with the commander noting that Iran is &quot;not joking with anyone.&quot; This aggressive stance has effectively neutralized the brief optimism that followed Friday&#39;s ceasefire announcement between Israel and Lebanon.<\/p>\n<p>Market reaction has been swift and severe as the &quot;fog of war&quot; returns to energy trading. While oil prices saw a temporary <strong>11% drop<\/strong> on Friday, the re-closure of the strait is expected to drive prices back toward record highs. Major energy producers like ExxonMobil (<a href=\"\/stock\/XOM\">XOM<\/a>) and Chevron (<a href=\"\/stock\/CVX\">CVX<\/a>) are being closely watched as supply chain disruptions worsen. Shipping giant A.P. M\u00f8ller &#8211; M\u00e6rsk A\/S (<a href=\"\/stock\/AMKBY\">AMKBY<\/a>) and other carriers have reported that tankers are now idling or diverting around the Cape of Good Hope, adding <strong>10-14 days<\/strong> to transit times.<\/p>\n<p>On the ground\u2014and at sea\u2014the situation is increasingly violent. The <strong>UK Maritime Trade Operations (UKMTO)<\/strong> reported that IRGC gunboats fired on a tanker approximately 20 nautical miles northeast of Oman. Simultaneously, maritime tracking services confirmed that an Indian-flagged supertanker carrying Iraqi crude was forced to reverse course after being intercepted. These incidents have caused insurance premiums for Gulf operations to skyrocket, with many underwriters now deeming transit through the strait &quot;suicidal&quot; without government backstops.<\/p>\n<p>The geopolitical stalemate shows no signs of easing as the US maintains its pressure campaign. President <a href=\"https:\/\/thestockmarketwatch.com\/live\/trump-stock-market\" data-internallinksmanager029f6b8e52c=\"8\" title=\"Trump\">Trump<\/a> reiterated that the <strong>US naval blockade<\/strong> of Iranian ports will remain in effect until Tehran agrees to a comprehensive deal involving its nuclear program and regional influence. As the United States Oil Fund (<a href=\"\/stock\/USO\">USO<\/a>) reflects the growing uncertainty, analysts warn that the disconnect between current spot prices and long-term futures suggests a massive market reckoning is imminent if the 20% of global oil flowing through the strait remains blocked.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways IRGC Navy commanders warned the US Navy will receive a &quot;hard blow&quot;
