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

The S&P 500 fell as much as 1.1% after Trump said the agreement to pause fighting was “over,” but the index then trimmed its loss to 0.3% after Trump said the most recent exchange of fire with the Islamic Republic did not herald a return to full-scale war. They’re his latest mixed messages on what will happen with the war, which threatens to worsen inflation for the world.
