Investing.com - Global shares fell sharply on Thursday after two sessions of gains, with sentiment depressed by the latest plunge in oil prices.
Global benchmark Brent fell below $30, to the lowest level since 2004 overnight and U.S. crude also fell in early trade.
Canada, one of the big global oil producers, saw its dollar fall to the lowest level since April 2003 against the greenback.
Europe's main markets were also sharply lower following heavy overnight selling in Asia.
Investors were looking ahead to the outcome of the Bank of England's policy meeting and European Central Bank meeting minutes later in the day for fresh signals on monetary policy.
