Stock Market Declines Amid AI Safety Concerns, Rising Yields

U.S. stocks declined on Monday as leading artificial intelligence companies called for an industrywide slowdown in development to address safety concerns. The warnings from Anthropic and OpenAI contributed to a sell-off in chip stocks, which dragged down the Nasdaq Composite despite gains by Big Tech firms. Meanwhile, rising oil prices and elevated Treasury yields added pressure to equities ahead of the Federal Reserve's policy meeting this week. The Dow Jones Industrial Average fell 0.3%, while the S&P 500 dropped 0.5%. The tech-heavy Nasdaq Composite initially lost up to 1.5% but pared losses slightly, ending down 0.5%. Anthropic CEO Dario Amodei and OpenAI's Sam Altman both urged a slower pace of AI development in recent posts, contradicting Wall Street expectations for rapid innovation. Separately, Bank of America shares fell over 5% after the bank issued weaker-than-expected forecasts for dealmaking fees. The broader investment banking sector is expected to see a roughly 10% decline year-over-year.
