The vessel, identified as the Guinea-Bissau flagged <strong>M\/T Jalveer<\/strong>, was targeted after violating the blockade by attempting to transport Iranian oil. This marks the third commercial ship disabled by U.S. forces this week, following the disabling of the <strong>M\/T Marivex<\/strong> and <strong>M\/T Settebello<\/strong> on Monday and Tuesday.<\/p>\n<p>CENTCOM emphasized that the blockade is being enforced <strong>impartially<\/strong> against all nations entering or departing Iranian ports. Since the operation&#39;s inception on April 13, U.S. forces have redirected <strong>135 ships<\/strong> and allowed <strong>42 vessels<\/strong> carrying humanitarian aid to pass. <em>The aggressive enforcement has led to a dramatic drop in Iranian crude shipments, with monitoring groups reporting near-zero exports through the blockade zone in recent weeks.<\/em><\/p>\n<h2>Political Turmoil in the United Kingdom<\/h2>\n<p>In a major blow to the Starmer administration, <strong>John Healey<\/strong> resigned as UK Defense Secretary on Thursday. In his resignation letter, Healey accused the Prime Minister and the Treasury of being &quot;unwilling to commit the resources&quot; necessary to defend the nation. He specifically noted that the government&#39;s <strong>Defense Investment Plan<\/strong> falls &quot;well short&quot; of requirements during a period of escalating regional conflict.<\/p>\n<p>The resignation comes as the UK faces increasing pressure to clarify its role in the <strong>U.S.-led operations<\/strong> against Iran. <em>Market analysts suggest the political instability could weigh on defense-related equities and the British Pound as investors assess the future of UK military readiness and procurement.<\/em><\/p>\n<h2>Regional Conflict and Economic Fallout<\/h2>\n<p>Tensions in the Middle East reached a new peak as the <strong>Bahraini Foreign Minister<\/strong> confirmed that more than 36 Iranian drones attacked the country early Thursday morning. The <strong>UAE<\/strong> issued a stern warning, stating that Iran&#39;s &quot;aggressive attacks&quot; represent a blatant violation of sovereignty for Bahrain, Kuwait, and Jordan. <em>The escalation pushed Brent crude prices toward $97 per barrel as traders priced in the risk of broader supply disruptions.<\/em><\/p>\n<p>In response to these geopolitical headwinds, the <strong>Central Bank of the Republic of Turkey<\/strong> left its one-week repo rate unchanged at <strong>37%<\/strong>. The bank noted that while it had previously ended its easing cycle, the &quot;pronounced&quot; inflationary effects of the Iran war require a cautious stance. Turkey, a major energy importer, is particularly vulnerable to the surge in <a href=\"https:\/\/stockmarketwatch.com\/energy\/crude-oil\" data-internallinksmanager029f6b8e52c=\"12\" title=\"Crude oil\">oil prices<\/a> caused by the effective closure of the <strong>Strait of Hormuz<\/strong>.<\/p>\n<h2>Global Market Briefs<\/h2>\n<ul>\n<li><strong>China Summons Carmakers:<\/strong> Chinese regulators have summoned major automotive manufacturers, including BYD (<a href=\"\/stock\/BYDDF\">BYDDF<\/a>) and BAIC Group, to address &quot;irrational competition.&quot; The government is seeking to curb aggressive price wars in the EV sector that have pressured margins for both domestic players and foreign rivals like Tesla (<a href=\"\/stock\/TSLA\">TSLA<\/a>).<\/li>\n<li><strong>South African Manufacturing Slump:<\/strong> South Africa&#39;s industrial sector faced a sharp contraction in April, with manufacturing output falling <strong>2.9%<\/strong>.
