European Equities Rally as US-Iran Diplomacy Offers Geopolitical Relief

European equity indices surged on Tuesday, buoyed by optimism that diplomatic channels between Washington and Tehran remain open despite escalating tensions. The pan-European STOXX 600 rose 0.8% to 618.72, reversing previous losses as investors reacted to reports of a second round of negotiations to resolve the ongoing conflict. The rally occurred even as a U.S. blockade of Iranian ports officially took effect. This duality of escalation and diplomacy triggered a risk-on mood, causing government bond yields to dip and the U.S. dollar to slide to its lowest level in six weeks. Regional indices showed broad strength, with the German DAX leading gains at 1%, followed by France's CAC 40 at 0.7% and the UK's FTSE 100 up 0.2%. In the energy sector, oil prices retreated below $100 per barrel as the market priced in the potential for a diplomatic resolution. Corporate earnings provided a mixed backdrop. LVMH shares fell nearly 2% after reporting a 6% decline in first-quarter revenue, citing disruptions from the Middle East conflict. Conversely, Swiss technology firm Comet Holding soared 9% on strong order intake, and Publicis Groupe gained 1% after confirming full-year guidance and reporting 4.5% organic growth. Other notable shifts included Eurofins Scientific jumping over 5% following an agreement to sell its electronic testing unit to UL Solutions, while Imperial Brands plummeted 7.4% due to increased investment losses in next-generation products. BP Plc saw a slight decline of 0.5% as the company projected flat upstream production for the first quarter.
