European equities weakened across Monday and Tuesday, with the STOXX 600 falling 0.35% to its weakest level in more than three months and major national indices reaching multi-month lows as geopolitical tensions, rising oil prices, elevated bond yields, weaker UK labor data and uncertainty ahead of the Federal Reserve decision unsettled investors. Brent crude later rose 1.2% above $113 a barrel after attacks on Saudi infrastructure, while an earlier market report cited a 1.67% rise to $107.42 following disruption to the East-West pipeline system. Markets assigned a 90% probability to a 25-basis-point Federal Reserve increase on Wednesday, potentially the first since mid-2023. Technology and AI-infrastructure stocks also faced pressure after OpenAI and Anthropic executives called for a temporary pause or slower development of advanced AI and stronger international safeguards, raising concerns about data-center investment and demand for Bloom Energy’s fuel cells.
