US stock market today: Dow, S&P 500, and Nasdaq dropped as Trump's tariff threats and a looming U.S. government shutdown unsettled investors. The Dow fell 0.31% to 41,223.97, while the Nasdaq and S&P 500 also declined. Meanwhile, inflation data showed a stable Producer Price Index, sparking hopes for Federal Reserve rate cuts. However, uncertainty over a 200% tariff on EU wines and spirits and Senate Democrats blocking a spending bill added to market jitters. With volatility rising, investors are watching the Fed’s next move and political developments closely.
