U.S. stocks are sinking after another climb for oil prices raised worries about inflation, which may have been primed to worsen even before the war with Iran began. The S&P 500 fell 0.5% Wednesday and was on track for its first loss this week. The Dow Jones Industrial Average dropped 377 points, and the Nasdaq composite fell 0.5%. Stocks slipped as rising Treasury yields cranked up the pressure. A report showed inflation unexpectedly accelerated last month at the U.S. wholesale level. That strengthened the consensus that the Federal Reserve will not announce a cut to interest rates in the afternoon.
