According to reports from the <em>Financial Times<\/em>, the chipmaker has implemented a new &quot;white list&quot; of vetted customers in <strong>Singapore, Malaysia, and Japan<\/strong> to ensure compliance with US export controls. This move follows intense pressure from Washington to close &quot;gray market&quot; loopholes that have allowed advanced AI hardware to reach Chinese entities despite federal bans.<\/p>\n<p>The crackdown comes after US prosecutors recently charged individuals with smuggling approximately <strong>$2.5 billion<\/strong> worth of <a href=\"https:\/\/stockmarketwatch.com\/stock\/NVDA\" data-internallinksmanager029f6b8e52c=\"15\" title=\"stock: NVDA\">Nvidia<\/a> (<a href=\"\/stock\/NVDA\">NVDA<\/a>) chips into China via Southeast Asian proxies. While the company\u2019s stock remains a &quot;Strong Buy&quot; among analysts with an average price target of <strong>$301.62<\/strong>, these supply chain disruptions highlight the growing geopolitical risks facing the semiconductor industry. <em>Market analysts suggest that while the move protects <a href=\"https:\/\/stockmarketwatch.com\/stock\/NVDA\" data-internallinksmanager029f6b8e52c=\"15\" title=\"stock: NVDA\">Nvidia<\/a> from regulatory penalties, it may temporarily impact sales volumes in the broader Asian market.<\/em><\/p>\n<h3>US Reestablishes Iran Blockade; Oil Markets React<\/h3>\n<p>The Biden-Trump transition period has seen a sharp escalation in Middle Eastern maritime policy, with the US Central Command (CENTCOM) announcing a total blockade of Iranian ports starting today. The blockade covers all vessels regardless of flag and is intended to halt Iranian oil exports entirely. In response, <strong>Brent crude futures<\/strong> skyrocketed by <strong>$7.29 per barrel<\/strong>, marking the largest single-day dollar gain in months as traders price in a significant supply shock.<\/p>\n<p>President Trump further intensified market volatility by demanding a <strong>20% fee<\/strong> on all cargo transiting the Strait of Hormuz, claiming the US must be &quot;reimbursed&quot; for maintaining security in the waterway. Ship-tracking data from <em>Bloomberg<\/em> indicates that at least <strong>six Iranian supertankers<\/strong>, carrying an estimated <strong>12 million barrels of crude<\/strong>, have already attempted to &quot;sneak out&quot; of the Gulf with transponders disabled to evade the looming blockade.<\/p>\n<h3>IRGC Targets US Fifth Fleet in Bahrain<\/h3>\n<p>In a direct military escalation, the Islamic Revolutionary Guard Corps (IRGC) announced the commencement of the &quot;Nasr 2&quot; operation, targeting US military infrastructure in <strong>Bahrain<\/strong>. Iranian state media reported that drone and missile strikes successfully hit the <strong>US Navy Fifth Fleet\u2019s air control radar<\/strong> and early-warning systems. While the US has not yet confirmed the extent of the damage, air raid sirens were reported across Bahrain, and the IRGC has warned that &quot;retaliatory operations are continuing.&quot;<\/p>\n<p>The strikes are reportedly a response to three consecutive nights of US airstrikes against Iranian coastal positions. This tit-for-tat cycle has effectively ended the 60-day ceasefire previously in place. <em>Defense analysts warn that the targeting of Patriot radar systems represents a significant shift in Iranian tactics, aimed at degrading US defensive umbrellas in the Persian Gulf.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Nvidia (NVDA) has more than halved its authorized Asia
