The announcement follows a series of kinetic attacks on commercial shipping, including reports from the <strong>United Kingdom Maritime Trade Operations (UKMTO)<\/strong> of multiple tankers being struck by naval mines and RPGs. Iranian state media, <em>IRNA<\/em>, claimed that two supertankers caught fire after hitting mines while attempting to navigate &quot;unauthorized routes&quot; with their tracking systems disabled.<\/p>\n<p>In a coordinated escalation, <strong>Saudi Arabia<\/strong> announced the interception and destruction of four drones launched toward its territory. The <strong>Saudi-led coalition<\/strong> confirmed that the drones were neutralized over <strong>Riyadh<\/strong>, the <strong>Eastern Province<\/strong>\u2014home to the kingdom&#39;s primary oil infrastructure\u2014and the <strong>Southern region<\/strong>. While no casualties were reported, the strikes highlight the widening scope of the conflict and the persistent threat to Saudi Aramco (<a href=\"\/stock\/ARMCO\">ARMCO<\/a>) facilities.<\/p>\n<p>The maritime blockade has effectively paralyzed one of the world&#39;s most vital energy arteries. Prior to the conflict, approximately <strong>19 million barrels per day (mb\/d)<\/strong> of crude oil flowed through the region; however, analysts report that traffic has plummeted by over <strong>90%<\/strong> as war risk insurance premiums reach prohibitive levels. Iranian Foreign Minister <strong>Abbas Araghchi<\/strong> has reportedly transmitted a &quot;seven-day plan&quot; to the U.S. government via Qatar, stating that the strait will only reopen if specific conditions, including a U.S. military withdrawal from the region, are met.<\/p>\n<p>Market reaction has been swift and severe, with energy majors such as ExxonMobil (<a href=\"\/stock\/XOM\">XOM<\/a>), Chevron (<a href=\"\/stock\/CVX\">CVX<\/a>), and Shell (<a href=\"\/stock\/SHEL\">SHEL<\/a>) monitoring the situation closely as supply chains fracture. While Saudi Arabia has attempted to mitigate the impact by rerouting some exports through Red Sea pipelines, the closure of Hormuz removes nearly <strong>15 mb\/d<\/strong> of global supply from the market. <em>Financial analysts warn that a prolonged closure could push oil prices well above the $150 mark, further fueling global inflationary pressures.<\/em><\/p>\n<p>Adding to the regional instability, the semi-official <strong>Fars News Agency<\/strong> reported a series of loud explosions in southern Iran near the <strong>Kuhstak<\/strong> area and the city of <strong>Sirik<\/strong>. While the cause of these blasts remains unconfirmed, they occurred shortly after the reported maritime incidents in the <strong>Sea of Oman<\/strong>. The Iranian Navy has warned that any vessel violating its &quot;prohibited zones&quot; will face immediate interdiction, signaling a shift from harassment to direct military engagement with commercial tonnage.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Iran\u2019s Islamic Revolutionary Guard Corps (IRGC) has declared the Strait of Hormuz &quot;closed,&quot;
