European stock markets experienced a downturn on Monday, with the pan-European STOXX 600 index falling 1.1% to 619.67 points. The decline was driven by renewed fears regarding the stability of a ceasefire between the U.S. and Iran, particularly after the U.S. seized an Iranian cargo ship. Iran's refusal to engage in further negotiations has added to market uncertainty. Major European markets, including France's CAC and Germany's DAX, also recorded losses of 1% and 1.6%, respectively. This decline contrasts sharply with last Friday's gains, where the STOXX 600 had risen over 1% due to optimism surrounding the Strait of Hormuz's reopening. The European markets are struggling to recover losses from the ongoing conflict, with elevated oil prices causing additional strain on energy-dependent economies. Daniela Hathorn, a senior market analyst at Capital.com, noted that the U.S. is better positioned to handle the crisis, which is contributing to the lag in European equities compared to their U.S. counterparts. Despite the overall market decline, energy shares saw a 1.7% increase, although major oil companies like BP and Shell faced declines between 2.5% and 3.1%. The travel and leisure sector was hit hardest, dropping 2.5%, with airline stocks such as easyJet and Lufthansa falling between 3.1% and 4%. Among individual stocks, Renishaw's shares surged by 6.7% after raising its revenue forecasts, while Loomis fell 6% due to a downgrade from Goldman Sachs.
