Wall Street Falls as Hot US Inflation Fuels Fed Rate Hike Bets
Wall Street indices fell Wednesday after hotter-than-expected US inflation data raised Fed rate hike bets. S&P 500, Nasdaq, and Dow Jones declined. CPI rose 0.6% month-over-month, with annual inflation at 3.7%. Tech shares dropped, while healthcare stocks gained. Treasury yields initially surged but later retreated. Corporate earnings from Bank of America, Morgan Stanley, and BlackRock influenced sentiment.
