According to BlockBeats, on September 15th, concerns about the risks of developing cutting-edge models in the artificial intelligence industry intensified, coupled with the deteriorating situation in the Middle East pushing up energy prices. According to BIT (bit.com) data, US stocks closed lower across the board on Monday. The Philadelphia Semiconductor Index plunged nearly 6%, the Nasdaq 100 Index fell 0.8%, and all eight sectors of the S&P 500 Index declined, with the technology sector falling 1.7%. Optical communication stocks led the declines, with Corning (GLW) falling 13.74% and Nokia (NOK) falling 13.25%. Among star stocks, SK Hynix fell 7.6%, Nvidia fell 3.4%, and CoreWeave fell nearly 7%.

Anthropic CEO Dario Amodei issued a statement exceeding 3,800 words, calling for a slowdown in the development of cutting-edge AI models, and received support from OpenAI CEO Sam Altman and SpaceX CEO Elon Musk. Market concerns about the potential impact on AI commercialization and capital expenditure put pressure on the chip, computing power, and optical communication sectors; however, the cybersecurity sector bucked the trend, with CrowdStrike and Palo Alto Networks rising 14% and 13%, respectively.

An attack on Saudi Arabia's east-west oil pipeline caused oil prices to surge as much as 5% intraday, with WTI crude briefly approaching $105 per barrel, according to Bitget data. However, after Trump stated that Russia and Ukraine had agreed to cease attacks on each other's energy targets, oil prices subsequently gave back most of their gains, with WTI ultimately closing up about 1.7% at $101.75 per barrel. Rising energy prices have exacerbated inflation concerns, and the market now expects a greater than 90% probability of a 25 basis point rate hike by the Federal Reserve this week.

The 10-year US Treasury yield rose above 5% intraday, the first time since October 2023, marking its sixth consecutive day of gains, before closing near 4.99%.
