Wall Street, already on edge over the next tariff announcements from President Donald Trump, turned lower early Thursday ahead of the latest data on inflation and layoffs.

U.S. equity futures edged lower in early Thursday trading, while Treasury yields and the dollar bumped higher, as investors added the threat of a U.S. government shutdown to a growing list of concerns tied to the fate of the world's biggest economy.

A critical inflation report in the coming week could further rattle an increasingly tumultuous U.S. stock market, with investors worried about an economic growth slowdown and President Donald Trump's tariffs.
