英格兰银行警告潜在的人工智能驱动市场调整
摘要
英格兰银行警告称，人工智能相关股票估值飙升可能导致市场出现急剧调整，类似于2000年互联网泡沫。
英格兰银行发出警告称，如果投资者对人工智能（AI）的情绪转为负面，全球金融市场可能面临急剧调整。在其最新的金融政策委员会（FPC）报告中，央行指出，美国股票估值，特别是聚焦于人工智能公司的估值，正接近2000年互联网泡沫高峰时的水平。
FPC指出，标普500指数的集中度日益加剧，五大科技公司——英伟达、微软、苹果、亚马逊和Meta——占据了其总估值的30%。这是五十年来市场集中度的最高水平。
委员会强调，这种集中度加上高估值，使得股市在对人工智能影响的预期变得不那么乐观时，特别容易受到冲击。
英格兰银行还表达了对如果美国联邦储备委员会独立性受到政治压力影响而受损，可能引发全球不稳定的担忧。对联储可靠性的突然改变认知，可能导致美元资产价值，尤其是美国政府债券市场的急剧重新评估，进而引发波动加剧和全球性后果。
这些警告发布之际，主要股指创下历史新高，标普500指数今年迄今上涨14%，主要受益于对人工智能经济潜力的热情推动。
央行的谨慎立场强调，投资者需保持警惕，关注当前市场趋势的可持续性，尤其是在由技术进步驱动的快速增长行业。
