Oil prices rose, and stock markets dropped in shaky trading worldwide after President Donald Trump raised doubts about the temporary truce in the war with Iran.

The S&P 500 fell 0.3% Wednesday after sinking as much as 1.1% earlier in the day. The Dow Jones Industrial Average dropped 1.1% after Trump said the agreement to pause fighting was over. The Nasdaq composite erased an early slump and rose 0.2% after Trump said in the afternoon that the most recent fighting did not mean a return to full-scale war.

Brent crude oil’s price climbed 5% above $78 per barrel.
