US stocks moved lower Friday as a rebound in Treasury yields renewed concern about the macroeconomic outlook. The S&P 500 and Dow each declined 0.3%, while the Nasdaq 100 edged below unchanged. The 10-year Treasury yield climbed back above 5% as uncertainty over Middle Eastern oil supplies pushed fuel and natural-gas prices higher. The prolonged risk of energy-driven inflation has already affected underlying consumer prices and prompted the Federal Reserve to raise interest rates this week; most FOMC members also supported another increase. Banks and asset managers fell as credit-sensitive sectors weakened. AI hyperscalers (large firms operating extensive computing infrastructure) mostly declined amid heavy debt issuance to fund capital spending, with Oracle, Microsoft and Palantir losing between 1% and 3%. Chipmakers recovered somewhat after concerns about AI security risks had prompted investors to reassess the pace of spending on data centers and chips.
