The move follows new threats from the Iranian regime directed at the <strong>United Arab Emirates (UAE)<\/strong> and <strong>Abu Dhabi<\/strong>, heightening fears of a total maritime blockade.<\/p>\n<p><strong>Saeed Siah-Sarani<\/strong>, an IRGC Navy commander, warned that Iran will not allow any oil shipments through the critical waterway if it comes under attack. This escalation comes as <strong>Donald Trump<\/strong> reportedly promised Israeli Prime Minister <strong>Benjamin Netanyahu<\/strong> that the U.S. would &quot;finish the mission&quot; regarding Iran\u2019s nuclear program, with no compromise on enriched uranium.<\/p>\n<p>Market analysts at <strong>Goldman Sachs<\/strong> and <strong>Morgan Stanley<\/strong> warn that a prolonged closure of the Strait could push crude prices well above <strong>$150 per barrel<\/strong>. Major energy producers including ExxonMobil (<a href=\"\/stock\/XOM\">XOM<\/a>), BP (<a href=\"\/stock\/BP\">BP<\/a>), and Shell (<a href=\"\/stock\/SHEL\">SHEL<\/a>) are monitoring the situation closely as insurance premiums for tankers in the Persian Gulf continue to skyrocket.<\/p>\n<h2>North Korea\u2019s &quot;Automatic&quot; Nuclear Doctrine<\/h2>\n<p>In a significant shift in global security, <strong>North Korea<\/strong> has codified a new nuclear doctrine into its revised constitution. The updated text stipulates that a <strong>nuclear strike shall be launched &quot;automatically and immediately&quot;<\/strong> if the state&#39;s command-and-control system is threatened by a hostile attack or if an assassination attempt is made on <strong>Kim Jong-un<\/strong>.<\/p>\n<p>The move is seen as a direct response to the &quot;decapitation&quot; strategies utilized in recent regional conflicts. Defense contractors such as Lockheed Martin (<a href=\"\/stock\/LMT\">LMT<\/a>) and Northrop Grumman (<a href=\"\/stock\/NOC\">NOC<\/a>) saw increased interest in Friday&#39;s trading session as the &quot;nuclear trigger&quot; system removes previous ambiguities regarding Pyongyang&#39;s threshold for escalation.<\/p>\n<h2>Political Instability in the United Kingdom<\/h2>\n<p>Domestically, the UK government has been plunged into crisis as <strong>Catherine West<\/strong>, a former minister and MP for Hornsey and Friern Barnet, threatened a leadership challenge against <strong>Sir Keir Starmer<\/strong>. The move follows a &quot;crushing&quot; local election defeat where the Labour Party lost control of key councils like <strong>Lambeth<\/strong> and <strong>Lewisham<\/strong> to the Green Party.<\/p>\n<p>West has given the Cabinet until Monday to arrange an orderly transition, warning she will seek the <strong>81 signatures<\/strong> (20% of the PLP) required to trigger a formal contest if no senior minister steps forward. The political uncertainty has weighed on the British Pound, as investors weigh the potential for a leadership vacuum during a period of intense global volatility.<\/p>\n<h2>Energy and Aviation Impact<\/h2>\n<p>In a rare piece of positive news for the energy sector, Libya\u2019s <strong>Zawiya Refinery<\/strong> (120,000 bpd) resumed operations on Sunday following a two-day halt caused by nearby clashes. The facility is a critical link to the <strong>Sharara oilfield<\/strong>, and its return provides essential supply to a market already strained by the <strong>Hormuz crisis<\/strong>.<\/p>\n<p>Meanwhile, the aviation sector is beginning to implement contingency plans to mitigate rising fuel costs and supply risks. <strong>Swiss Air<\/strong> CEO (part of the Lufthansa Group (<a href=\"\/stock\/LHA\">LHA<\/a>)) stated that while there is no immediate fuel shortage, the airline is eyeing &quot;tankering&quot; operations\u2014where aircraft carry extra fuel to avoid refueling in high-cost zones\u2014to maintain its summer schedule.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Iran\u2019s IRGC Navy has placed light submarines in a
