- Oil plunges, stocks soar -

Oil and natural gas prices dropped sharply Wednesday as investors breathed a sigh of relief after the ceasefire between the United States and Iran, which should see tanker traffic resume through the Strait of Hormuz.

Fears of a prolonged war that would crimp global energy supplies sent oil prices soaring since the US and Israel began airstrikes on Iran on February 28, raising the spectre of widespread inflation that would threaten economies worldwide.

Stock markets in Europe opened broadly higher on the ceasefire, following strong gains seen in Asia, while the dollar -- a haven for investors during market turbulence -- fell back against the euro and pound.
