LONDON: Oil prices plunged yesterday, mirroring the direction of stock markets and gold prices, a day after Federal Reserve chairman Ben Bernanke signalled that US central bank would wind down its stimulus programme this year. Brent North Sea crude for delivery in August slumped $3.25 to stand at $102.81 a barrel in late London deals. New York’s main contract, light sweet crude for July, shed $2.82 to $95.42 a barrel. AFP
