While a final decision to withdraw has not been made, officials stated the move depends entirely on <strong>Washington&#39;s behavior<\/strong> and ongoing &quot;aggression&quot; from Israel. Iran has reportedly shifted its strategic stance toward the U.S. following the collapse of recent diplomatic memorandums.<\/p>\n<p>In a show of force, Tehran confirmed it recently <strong>tested an anti-ship missile in close proximity to a U.S. aircraft carrier<\/strong>. Iranian officials warned that they are &quot;more prepared than ever&quot; to counter air attacks and will target <strong>U.S. bases and regional interests<\/strong> with &quot;greater force&quot; if provoked. Despite the bellicose rhetoric, Mohsen Rezaei noted that consultations are ongoing via <strong>Qatari and Pakistani mediators<\/strong>, with Iran awaiting a response from President Trump regarding conditions to end the war and release frozen funds.<\/p>\n<h3>SpaceX Triggers Nasdaq 100 Rebalance<\/h3>\n<p><strong>SpaceX (<a href=\"\/stock\/SPACE\">SPACE<\/a>)<\/strong> is set to see its influence on the <strong>Nasdaq 100 (<a href=\"\/stock\/NDX\">NDX<\/a>)<\/strong> surge as its index weighting jumps from 1.28% to <strong>2.82%<\/strong> this Monday. The adjustment follows the expiration of lock-up periods that previously suppressed the aerospace giant&#39;s weighting after its July addition. With a market valuation exceeding <strong>$2 trillion<\/strong>, SpaceX now stands as the seventh-largest constituent in the index.<\/p>\n<p>This rebalance will trigger significant trading activity as benchmark-tracking products, including the <strong>$482 billion Invesco QQQ Trust (<a href=\"\/stock\/QQQ\">QQQ<\/a>)<\/strong>, must buy shares to match the new allocation. Investors are bracing for heightened volatility in the final minutes of trading as passive funds realign their portfolios to reflect the company&#39;s true market scale.<\/p>\n<h3>Energy Markets and Regional Conflict<\/h3>\n<p>Regional stability took a hit as <strong>Houthi forces targeted Riyadh International Airport<\/strong>, successfully striking fuel storage infrastructure. The attack comes even as U.S. Admiral Brad Cooper reported that <strong>Strait of Hormuz oil shipments<\/strong> have reached a six-month high. Naval protection efforts have allowed approximately <strong>10 million barrels per day<\/strong> to transit the strait, easing some global supply concerns despite the persistent threat of maritime disruption.<\/p>\n<p>In the corporate energy sector, <strong>TotalEnergies (<a href=\"\/stock\/TTE\">TTE<\/a>)<\/strong> CEO Patrick Pouyann\u00e9 revealed that over <strong>$6 billion<\/strong>\u2014half of the project&#39;s $12 billion budget\u2014has already been deployed for the <strong>GranMorgu project<\/strong> in Suriname. The offshore site is on track to begin production in <strong>mid-2028<\/strong>, according to Staatsolie, representing a critical future pillar for the company\u2019s output.<\/p>\n<h3>Trade Strains and Global Leadership<\/h3>\n<p>Deepening political rifts between Washington and Ottawa are beginning to fracture the <strong>$6 trillion Great Lakes regional economy<\/strong>. New U.S. tariffs on steel and iron ore have contributed to a <strong>23% decline in cargo traffic<\/strong> at the Port of Duluth-Superior through August. Industry stakeholders warn that these &quot;regulatory disparities&quot; and trade frictions could cause permanent damage to binational supply chains if a resolution is not reached soon.<\/p>\n<p>In European security developments, <strong>German General Carsten Breuer<\/strong> has been selected to lead <strong>NATO\u2019s Military Committee<\/strong>. This leadership transition occurs at a pivotal moment as the alliance navigates heightened tensions in the Middle East and ongoing trade disputes that threaten to spill over into broader transatlantic relations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Iran threatens withdrawal from the Nuclear Non-Proliferation Treaty (NPT), citing U.S. and Israeli actions and a shift in
