The safe-haven yen and Swiss franc climbed in volatile trading on Thursday, while the dollar slumped against most currencies, as jittery investors turned increasingly risk-averse amid an extended sell-off on Wall Street triggered by an escalating trade war initiated by the United States.

Wall Street has wiped out the gains made since President Trump’s election victory, as investors’ hopes of business-friendly policies have given way to fears over tariffs.

The Trump administration had postponed the implementation of the new levies on Mexico and Canada, the United States' largest trade partners for one month. But the reprieve ends on Tuesday.

Wall Street stocks tumbled Tuesday after the United States proceeded with new tariffs on Canada, Mexico and China.

Uncertainty over President Donald Trump’s tariffs rattled Wall Street on Thursday, sending the Dow Jones Industrial Average tumbling by more than 400 points, or 1%.

NEW YORK (AP) — Wall Street is careening again on Friday and swerving from gains to losses. It’s a fitting ending to a brutal week of scary swings dominated by worries about the U.S. economy and uncertainty about what President Donald Trump will do with tariffs.

U.S. stocks rose, but only after careening through another wild day. The S&P 500 climbed 0.6% Friday after erasing an earlier loss that reached 1.3%.

U.S. stocks climbed Wednesday after President Donald Trump pulled back on some of his tariffs temporarily. The move revived hope on Wall Street that Trump may avoid a worst-case trade war that grinds down economies and sends inflation higher.

It has certainly struggled. The stock market's main benchmark, the S & P 500, has been dropping since setting an all-time high last month, largely because of worries about President Donald Trump's tariffs and signals that the U.S. economy is running less powerfully than economists expected.

Liberals and government employees aren’t the only people angry with Elon Musk. Tesla’s plunging share price means many investors are angry, too.
