Wall Street ended sharply lower on Thursday and the S&P 500 confirmed it is in a correction after cool inflation data was overshadowed by fears that the escalating, hydra-headed tariff war being waged by the United States against its biggest trading partner could reignite inflation and tip the economy into recession.

In the bond market, Treasury yields lost an early gain to sink lower. The yield on the 10-year Treasury fell to 4.26% from 4.32%. The yield has been mostly dropping since January, when it was approaching 4.80%, as traders and economists have ratcheted back their expectations for U.S. economic growth.

U.S. stock indexes rose Wednesday after Wall Street got some relief from an encouraging inflation update. But even on a rare up day for the market, President Donald Trump’s trade war still knocked stocks around.
