Oil prices rose and major stock indexes fell after reports emerged that four ships received warning shots while trying to cross the Strait of Hormuz. The incidents occurred as Iran seeks greater oversight of the strategic channel. Global powers have opposed the move.

Oil prices climbed on the news while equity markets slipped.

ABN AMRO economists said prices would likely stay elevated for the coming quarters even if the strait reopens soon. The number of vessels attempting transit has declined further in recent days.
