"Volatility has picked up in markets - crude has been at the epi-centre of this, with WTI crude falling 6.6% and having the second big leak in a week," Pepperstone head of research Chris Weston said.
Base metals were mostly lower on the London Metal Exchange, with copper falling 1.51% to below $9,000 per tonne, to $8,979/t.

Fire River Gold (TSXV: FAU.H) was an exception in Toronto yesterday, up 44% to close at a one-year high of C44c on no news.

It said the proceeds were for the company's general working capital.
In London, Premier African Minerals (AIM: PREM) saw a big volume traded but closed down 13.3% to 22p.

Finally among the majors, Newmont closed down 1.26% in New York, Rio Tinto lost 0.76% in London and BHP was flat in morning trade.
